. ,.1 POISING-CALIPERS.
Application filed October 23, 1907.
To. all whom it may concern:
Be it known that l, FRANK R. CUNNING- HAM, of Medt’ord, in the county oi’ Middlesex and State o’t Massachusetts, have invented certain new and useful Improvements in Poising-Calipers, o’tl which the following is a specification.
The present invention consists in a tool for holding balance wheels oi’ watch or clock movements while being poised.
The objects are to provide a tool of this character permitting more rapid insertion and removal of work than in the poising tools heretol’ore used, lto permit an accurate adjustment ot’ the bearings tor the stattl ot’ ay balance wheel, to hold the same without looseness and also without end pressure, to provide a novel form of jewel bearing t’or the ends et’ a statt constructed with two jewels made separable so that they may be cleaned, and to provide other improved details oit’ construction which will be hereinafter more particularly described.
Of the accompanying cliavings,-Figiii’e 1 represents an elevation ot a tool embodying the principles of my invention. Fig. Q represents a sectional view of the same on an enlarged scale. Fig. 3 represents a crosssection on .line 3—3 ot Fig. 2. lF it represents an enlarged section through the bearings, illustrating in detail the construction thereof.
The same reference characters indicate the same parts in all the figures.
The instrument consists ot’ a frame 1 carried by a handle 2, and having arms 3 and 4l. These arms are separated somewhat and are absolutely rigid. having no relative movement of approach or recession whatever. In one of the arms, as. 4, is set a pin 5 passing entirely through the arm and having a threaded shank G on the inner side of the arm, to which shank is attached a stationary bearing 7. On the other arm is a tubular guide 8 in which is slidably contained a bar 9 carrying a movable bearing l0. The pin 5, bar 9 and bearings are all in line, and the movable bearing reciprocates on this line toward and from the fixed bearing. For so moving the bearing 10, l. provide an actuating lever 11 contained in a slot 12 in the arm 3, and pivoted upon a pin 18 in the caliper loody at the base of this arm.

tion is made between the lever and slide 9 by means ota pin t-‘lon the latter, and resilient lingers l5 ,ttt on the end ot’ the lever. These fingers are separated by a slot 1G which, when the lever is free of the pin. is ot less width than the diameter et’ the latter. Consequently the insertion of the pin into this slot spreads the lingers apart somewhat, causing` them to embrace the pin and thus absolutely preventing any lost motion between they level.’ and slide.
ln the base ol” the caliper Yframe is formed a passage containing a plunger 17, a spring 1S pressing said plunger outward, and an abutment screw itt). The plunger bears against the lever 1l on the opposite side of its pivot ‘from the slide 9. and so tends to press the slide and the bearing carried thereby toward the fixed bearing 7. Threaded into the aliper -trame is a screw Q() which projects toward the lever 11 on the, opposite side o’t` the pivotV ,13 trom the sjn’ing-pressed plunger. This screw is in the path of the lever and serves as a stop to limit the approach ot the niovable bearing toward the fixed one. By turning the outer end of the screw, its position can be altered, and the distance between the bearings when brought to restv` adjusted. ly means o’tE this adjustment, the bearings can be separated so as to remove all t’rietion-producing pressure from the ends ot the sta tll held between them, and at the same time retain the stati without looseness. AV spring Q1 bears against the stop screw and holds one side ot its threads in engagement with the eomplemental thread oi the socket, wherein it is contained, thereby taking up any looseness which there may be. This stop is designed to limit the approach ot the mo vable bearing 10 toward the tixed one, and to adjust the space between the bearings so exactly that the statil ot’ a wheel may be held between them without friction-causing pressure on its end, and also without too great looseness. The actuating lever causes the movable bearing to be advanced toward and withdrawn from the fixed bearing rapidly so that wheels may be inserted and removed with the greatest convenience, while the adjustable stop serves to tit’y the bearings tor staffs ot all sizes. The connection between the lever and slide consisting ot the pin 14 in the slot 16, allows the slide to move. rectilinearly, while the resilience of the spring fingers causes them to bear with the same pressure on each side of the pin and so eliminate lost motion. This result, elimination of looseness, is further forwarded by the spring-pressed plluiger 1T’, which normally presses the b arings together’ and tends to hold the lever in contact with the stop 20.
One of the important innirovements of my invention is the constuction of the bearings. These are provided with jewels against one of which the end of the statt bears, while the other surrounds the staff and holds it against sidewise movement, and are separable so that they may be easily cleaned and polished. The bearing ‘T consists of a main holder which has a base in the form of a nut, and is screwed upon the threaded end of the pin 5. n its tip this holder provided with a. socket in which is set an end-thrust bearing jewel 22 which has preferably a plane, or at least unrecessed, surface against. which the end of the balance wheel statt is adapted to bear. The holder’ 7 is threaded externallj7 and receives a screw cap Q4 constituting the holder for the second jewel 25 of the bearing. This jewel is annular, having a central hole through which projects the reduced pivot of the staff. The movable bearing l0 is essentially similar, consisting of the main holder to which the numeral l0 is applied, carrying the end bearing ewel 2Q, and being threaded to receive the cap 24k which holds the annular bearing jewel It differs from the other bearing, however. in this, that the main holder l0 is symmetrical withA respect to its ends, being threaded into a socket in the slide 9, and capable of being turned end for end. In its opposite end it carries a jewel 221 similar to the jewel 22, which can be put into use by simply reversing the holder l0 in the socket and applying the cap 2st to the other end. rlhis capability doubles the life of the bearing, permitting replacement of a defaced or unsuitable jewel without necessitating’ delay for repairs.
In using the instrument for poising a balance wheel, the staff of the latter is first set in the bearings and adjusted so that there will be no end shakeor friction. The weights of the screws which are set into the rim of the balance are then varied in the usual way until the center of gravity is eX- aetly in the axis of the staff. In order to determine if the wheel is perfectly poised, it is set. into rotation b v vibrating the ltool through rubbing upon a portion of it, thetool being held against the edge of a bench. T he rubbing is done by an instrument which has suflicieut friction to set the tool vibrating, thus causing the balance to be rotated. lf it is perfectly poised. it will continue rotating as long as the rubbing is kept up, but if not so poised, it will of course come to rest with its heaviest portion downward. It is for the purpose of it’urnishing a convenient member to take the rubbing without injury to the apparatus as a whole that l lprovide the detachable projecting pin After considerable use, the part of the apparatus which is rubbed upon will become worn a ‘ay, and if no provision were made for replacing the worn part, it would become unfit for use. lVhen, however, the pin 5 is worn away, no harm is done, because a new pin can readily be substituted.

DESCRIPTION  (OCR text may contain errors)

Specification.

This invention relates to screwdrivers and has for its object to enable fractions of a rotation of a screw-driver to be indicated and measured.

The principal application for which this tool is designed, is in connection with watch making, especially during the adjustment of the balance wheel. Most watch balances are provided with mean time screws, sometimes called simply timing screws, which are used to bring’ the watch approximately to the time when the regulator is at the center of its arc. These screws, being in some cases two, and in others four in number, are threaded into the rim of the balance approximately in line with the arms which connect the rim to the hub, and, when there are four, midway between such arms, and are given sufficient friction so that they will remain in any position with their heads clear of the rim. 

To make the watch run faster, the screws are turned inward, thereby reducing the moment of inertia of the balance, while to make it run slower, they are turned outward. The effect is analogous to the raising and lowering of a pendulum bob. To insure a uniform rate of oscillation of the balance in all positions of the watch, the balance must be perfectly poised. Unequal changing of the timing screws, subsequent to the poising of the balance wheel, is liable to destroy such poise unless diametrically opposite screws are turned precisely the same angle. It is primarily to enable the timing screws thus to be so turned that l have devised the present invention which have illustrated as applied to a watchmakers screwdriver, and having an index capable of measuring minute fractions of a rotation, and thereby still  distances through which the timing screws are advanced or retracted. By the use of the index, the diametrically opposite screws can be turned by exactly the same amount.

In the drawings, Figure l represents a sectional elevation of a watchmakers screwdriver embodying the principles of my invention. Fig. 2 represents an elevation of the lower part of the same, showing the micrometer. Fig. 3 is a longitudinal section showing the screw-driver blade reversed. Fig. 1 is a perspective of one of the elements of the screw-driver. Fig. 5 is a sectional plan on the line 5 5 of Fig. l. Fig. 6 is a sectional view showing a modification. Fig. 7 is a plan view of another’ modification. Fig. 8 is a longitudinal section of the parts shown in Fig. 7, the section being taken on the line 8-8 of said figure. Fig. 9 is a view showing the manner of use of the micrometer screw-driver.

The same numerals of reference indicate the same parts in all the figures.

The tool shown in the drawings has externally substantially the same form as the ordinary watchmakers or jewelers screwdriver, having the shank 1 and the button 2, which by endwise pressure may be applied, and the blade 3 detachable secured in the opposite end of the shank by means of chuck jaws 4l, and a tapered sleeve 5. The chuck jaws are connected with the shank 1 through the medium of the sleeve 6 which tits tightly over the end of the shank, and the end of a hub 7 on which the chuck jaws are formed. The sleeve 6 tits so tightly over the parts which it surrounds that they are securely held together and caused to rotate in unison. Surrounding the hub 7 between a disk or image 8 formed in the latter and a flange 9 on the sleeve 6, is a ring 10 which is loosely confined between the flanges 8 and 9 and is held stationary when the screwdriver is turned. This ring 10 has engraved upon it an index mark 11 which cooperates with a series of graduations 12 marked on the periphery of the disk 8, these marks constituting the cooperating or complemental indices by which fractions of a rotation of the screwdriver blade are indicated and measured. The ring or band 1() is held stationary by a ringer ring 13 which is adapted to surround the middle finger of the user’s hand, while the screw-driver is turned by his thumb and forefinger. The ends of the inner ring are snapped into a socket 14 which is swiveled upon a stud 15 secured in a stem 16 which projects from one side of the band 10. Thus the finger ring can be turned about three axes at right angles to each other, having universal motion with respect to the screwdriver.

The manner of use will be readily understood. The tool being held as shown in Fig. 9, the end of the blade is then inserted into the slot of the screw which is to be turned, and the index marks noted. The tool is then turned by the thumb and forefinger, while the band is held absolutely stationary, and at the end of the turning movement the number of graduations 12 which have passed the stationary mark 11 is noted. When the tool is used for setting the timing screws of a watch balance, both of the diametrically opposite screws are turned through precisely the same angle which is measured by the graduations 12. As shown in the drawings, the screwdriver blade is detachable from the body of the tool. It is formed upon a stem 17 of which the end opposite of the blade is slaved 0H to make a flat face. Rehearsals end passes through the bore of the hub 7, abuts against the shoulder 18 of the latter, as shown in Figs. 3 and e. This shoulder is formed owing to the fact that the bore at the upper end of the hub is of less diameter than at the lower end. Above the shoulder, the hub 7 is partly cut away leaving shoulders 19. When the stain 17 is rotated until it slabbed off side comes into the same plane with the shoulders 19, it can be slipped by into engagement with these shoulders, the end of the stem then lying in the open space indicated at 20. The shoulder 19 then prevent relative rotation between the body of the tool and the blade. Then not in use, the blade can be turned end for end being caused to enter a recess 21 in the shank of the tool as shown in Fig. 3, being thereby preserved from injury.

In the modification shown in Fig. 6, the band 10 is omitted and the button replaced by a fork 22 of which the shank 22 is freely rotatable in a sleeve 24, being headed over at the end to prevent it-withdrawal. The sleeve 24 is fitted tightly into the shank 1 of the tool and has a disk 25 lying beside a disk 26 secured to the fork. Release disks have complemental graduations which serve, instead of the disk 8 and band 10, to measure the rotation of the screw-driver.

In Figs. And S is shown a substitute for the finger ring 13. Instead of a divided ring, there here shows a partial fork 27, the arms of which are curved toward each other forming nearly a complete ring. A stem 2S on the ring has a ball 29 which is contained and has a universal movement within a socket 80. This Socket has an internally tapered and externally threaded sleeve 31 fitting on the tapered stud 161 which extends from the band 101. This threaded sleeve is split and is clamped upon the stud by a nut 52. v

It is to be understood that although I have  illustrated one embodiment of my invention and described one of the modes of its use, the invention is not limited to strict embodiment or such use, but may have many other forms and may be used in any relation where it would be necessary or desirable to measure the angles through which a screw-driver is rotated.

Claim 1. In combination with a screw driver, cooperating index devices, one of which is arranged to be rotated and the other held stationary by the hand of the user, graduated to indicate fractions of a rotation.

MULTIPLE TOOL.

Specication of Letters Patent.
Patented Jan. 2 6, 1909′.
Application filed September 11, 1908. Serial No. 452,621.
To all whom it may concern:
Be it lrnown that I, FRANK R. OUNNING- i HAM, of Medford, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Multiple Tools, of which the following is a specilication.
This invention relates especially to watchmakers tools such as are known as sleeve wrenches and are used to screw in or out the sleeve which is contained in the pendant of a stem-Winding watch.
The tool which constitutes the subject of the present invention contains a number of bits adapted to perform work of the same general character but on watches of different sizes.

The invention, however, is not limited in its application to tools of the particular character above indicated, but is of broader application and may embrace all kinds of multiple tools in which several tools of different sizes or characters are mounted upon a holder and adapted to be brought individually into position for operation.

The object of the invention is to so mount a plurality of tools and the holder by which they are carried that all or nearly all of the tools which are not in use are covered by a smooth shield which prevents the hand of the user from coming into contact with sharp edges, corners or points on the tools, and enables a firm grip to be obtained so that the particular tool which is being used when such a tool is a wrench, may be easily turned without danger of injury to the fingers of the user.

The character and construction ofthe invention are described in the following specification and shown in detail in the accompanying drawings, in which,-
Figure 1 represents an elevation of the tool. Fig. 2 represents a central vertical section thereof. Fig` 3 represents an elevation of the holder and the individual tool elements carried thereby, shown separate from the casing in which they are ordinarily contained. Fig. 4 represents a cross-sectional view of the complete tool. Fig. 5 represents an elevation of one member of the dividing casing in which the tool holder is mounted. Fig. 6 represents an elevation of a detent by which the tool holder is prevented from rotating when in the casing.
The same reference characters indicate the same parts in all the iigures.

o represents tool elements which may be of any character, and are shown in the drawings as being sleeve Wrenches for watchmakers use. These elements are all mounted upon an annular holder l) which in turn is supported in a casing or shell o so that it may rotate. The tool elements project radially from the outer periphery of the holder b and rotation of the latter will bring any one of the elements into position for use.

The shell c is of sufficient extent to cover and inclose nearly all of the tool elements, being of circular outline, but not continuing through a complete circle. Its lower part is out away so as to expose one or more of the tools in condition for use. This shell or casing is made in two parts, the front side of which is represented by c and the rear portion by d. The edges ofi, these parts are brought toward each other so as to meet and inclose a space of sufficient depth to accommodate the tool holder b. The part c of the casing has a tubular internal boss e upon which the tool holder is rotarily mounted, and there is also connected either integrally or detaohably with this part a handle The other member d of the casing’ has a per-v foration of suilicient size to receive the end of the tubular boss e, and when placed over the same is secured by a screw g which is threaded into the interior of the boss and has a head h which overlaps the surrounding edges of the casing member d. The boss is located at the center of curvature of the casing.

On opposite sides of the boss e are formed slots i through which project the teeth of a detent k. This detent is in the form of a plunger which slides in the tubularv boss and the end of which projects slightly from the outer face of the casin T member c, as shown in Figs. 2 and 4. A spring Z is contained within recesses in the plunger and screw g, and serves to hold the plunger outward so that its teeth are against or near the eX- tended plane portion of the casing member c.

The inner circumference of the annular tool holder l) which bears upon the boss e has notches m into which the teeth of the detent extend to loclr the holder against rotation. These notches are equal in number to the tool elements, and arranged so that two of them are occupied at the same time by the teeth of the detent. One side of the tool holder is recessed to provide an enlarged chamber n of which the circumference lies beyond the ends of the teeth This chamber is of a depth at least as great as that of the teeth, and ordinarily is somewhat greater, so that the detent when moved in opposition to the pressure of the spring Z, may be disengaged from the notches, its teeth 7′ then lying in the recess n free from any engagement whatever with the tool holder. This leaves the latter free to turn so that any one of the tool elements mounted upon it may be caused to project beyond the cut-away edges of the casing in position to be used. When the’ pressure which displaces the detent is removed, the spring returns it into the position shown in Figs. 2 and 4, so that its teeth will automatically enter two of the notches when the tool holder is turned to bring them into registry therewith.

The utility of the casing c is to serve both as a grip and as a protector. As it extends over the major part of the tool elements beyond the ends thereof, it ali’ords as great a leverage as the tool element itself can stand, which may be exerted in turning the operative element. lts smoothness and the fact that it completely shields the hand of the user from contact with the inoperative tool elements enables @it to be iirmly grasped and allows the user to apply his Jfull strength, if necessary, without harm to his hand.

The handle f may be grasped between the thumb and iingers to enable the tool to be more rapidly turned, after the work with which it is engaged has been started, than it can be when the turning force is applied to the shield alone.

WATCH-ROLLER REMOVER.

Specification of Letters Patent.
Patented Aug. 22, 1905.
Application filed March 1’7, 1905. Serial No. 250,609.
To whom it may concern:

Be it known that I, LESTER J. WILLIAMs, of Lebanon, in the county of Grafton and State of New Hampshire, have invented certain new and useful improvements in Watch-Roller Removers, of which the following is a specification.

This invention relates to tools used by watchmakers for removing from the staff of a watch-balance the disk known as the roller, said disk having a frictional fit upon the balance-staff.

The invention has for its object to provide a simple, inexpensive, and effective tool of this character which may be conveniently adapted for use with watch-balance staffs and rollers of different sizes.

The invention consists in the improvements which I will now proceed to describe and claim.
Of the accompanying drawings, forming a part of this specification, Figure 1 represents a sectional view of a roller-remover embodying my invention. Fig. 2 represents a perspective view of the part of the tool which includes the roller-seat. Fig. 3 represents a side elevation of the plunger-holder shown in section in Fig. 1. Figs. 4: and 5 represent sectional views of the barrel and screw-cap, respectively. Fig. 6 represents a side view showing a lever for projecting the plunger.
The same reference characters indicate the same parts in all the figures.

In the drawings, 12 represents a body or barrel, which is preferably cylindrical and is provided with a longitudinal bore having a larger portion 13 and a smaller portion 14, the latter serving as a guide for the plunger 15, which is pressed against the end of the balance-staff to force the same from the roller is preferably tubular and is provided with means such as an internal screw-thread 20, adapted to engage the external thread 17, for detaching and connecting the extension with the barrel. The seat 19 is preferably a head formed at the outer end of the extension 18 and is provided with a slot 21 to receive the balance-staff, the extension being cut away at one side to form an opening 22, which permits the application of the roller to the upper side of the seat 19. In practice each tool will be provided with a plurality of extensions 18, each formed for use with a different size of staff or roller, the several sections being adapted to be used interchangeably. The up per portion of the extension is preferably provided with a knurled or milled enlargement 23, constituting a handle, whereby the extension may be conveniently rotated to apply and remove it.

As shown in Fig. 1, the plunger 15 is double ended, that is to say, it has in each end a cavity 24:, adapted to engage the conical end of a balance-staff, one of said cavities being smaller than the other, so that the two are adapted for use with balance-staffs of different sizes. The plunger is reversible, so that either of its ends may be the acting end. 26 represents a holder which is adapted to be detachably engaged with the upper or inner end of the plunger, said holder being movable with the plunger in the enlarged portion 13 of the barrel-bore. The holder 26 is preferably a collar having a socket formed to receive one of the end portions of the plunger, the Walls of said socket being subdivided by longitudinal slots 27, Fig. 3, into spring-arms which normally spring inwardly to contract the socket. When the plunger is forced into the socket, it springs the arms outwardly and causes them to frictionally engage the plunger, so that the holder and the plunger are adapted to be moved together as one part. The holder 26 has a sliding it in the enlarged portion of the bore of the barrel. The spring 16 bears upon the inner end of the holder 26 and tends to force the latter and the plunger upwardly, thus normally retracting the plunger.
The plunger may be projected by any suitable projecting device. In Figs. 1 and 5 I have shown as the projecting device a cap 29, having an internal screw-thread 30 adapted to engage an external thread 31, formed on the upper portion of the barrel 12. The head of the cap 29 bears on the holder 26, the latter being pressed against the cap-head by the spring 16. When the cap is rotated in the direction required to feed it downwardly upon the barrel, it forces the holder and plunger’in the same direction, thus projecting the plunger and causing it to force the balance-staff from the roller. When the cap is rotated in the opposite direction, the spring causes the holder and plunger to move outwardly with the cap.

In Fig. 6 the projecting device is shown as a lever 32, pivoted at 33 to the barrel and having a projection which may bear upon a holder 26, like that shown in Fig. l, or directly upon the upper end of the plunger in case the latter is not made reversible. 34 represents an adjustable stop-screw to limit the downward movement of the lever which causes the projection of the plunger. 35 represents a shank suitably engaged with the barrel and provided with a handle 36. The stop-screw 34 is engaged with a tapped orifice formed in the said shank.

– I do not limit myself to the details of construction above described and may variously modify the same without departing from the rel, a holder adapted to detachably engage either end of the barrel, said holder being movable with the plunger in the barrel, and means for moving the holder to project and retract the plunger.

2. A tool of the character stated,comprising a barrel or body, a roller-seat secured thereto, a double-ended plunger movable in the barrel, a plunger-holder movable in the barrel and having a split socket adapted to automatically engage either end of the plunger, and means for moving the holder to project and retract the plunger.

3. A tool of the character stated,comprising a barrel or body, a roller-seat secured thereto, a double-ended plunger movable in the barrel, a holder adapted to detachably engage either end of the barrel, said holder being movable with the plunger in the barrel, an internally-threaded cap engaged with an external thread on the barrel and bearing on the holder, and a spring which presses the holder against the cap.

In testimony whereof I have affixed my signature in presence of two witnesses.

STAKING-TOOL. l
Specification of Letters Patent.
Patented May 16, 1911.
T o all whom ‘it may concern:

Be it known that I, FRANK B. KENDRICK, of Lebanon, in the county of Grafton and State of New ‘Hampshire have invented certain new and useful Improvements in Staking-Tools, of which ‘the following is a specification.

This invention relates to staking tools and has for its object to provide a novel means for binding the die in position so that any desired one of the apertures which receive the stumps may be retained in proper’position under the punch guide. It has hitherto been the general custom to bind the die in place by means ot’ a cam on a shaft extending through the base of the die from front to rear, the cam being contained 1n a slot in a vertical pin which passes through the base of the tool and is attached to or engaged with the die. The shaft carrying such cam or its equivalent and eccentric is provided with an external hand-wheel by which it may be turned to bindV the die by drawing it down upon the top of the base, and to release the same.

By the present invention I eliminate the cam, the shaft and the hand-wheel, securing the result of frictionally locking the `die by providing a nut located Within the base, which nut draws directly down upon the bolt or pin and so presses the die against its seat. By this arrangement the die-locking means is contained Within the base and protected from being accidentally displaced. This arrangement also enables the tool to be made without unnecessary external projections, and renders it more compact, besides diminishing the liability of the tool being caught or struck by external moving objects.

Of the accompanying drawings,-Figure 1 represents a side elevation, partially in section, of a staking tool constructed 1n accordance with this invention. Fig. 2 represents a section on line 2-2 of Fig. l. Fig. 3 represents a section on line 3 3 of Fig. 1. Fig. 4 represents a section, on a smaller scale, on line 4-4 of Fig. 2.

The same reference characters indicate the same parts in all the figures.

The tool comprises the usual base a having a neck b and a head c forming a guide for a punch or centering tool. The base has a flat top on which rests the circular die (l having a series of apertures of graded sizes.

A pin or bolt c passes through the base and has a head for engaging the die and acting when depressed to bind the latter against its seat on the base. There is a passage through which the bolt extends, this passage being enlarged at the bottom of the tool to form a recess or chamber it which is bounded by a flat annular shoulder z’ extending from the walls of the passage outward to the walls of the recess.

The end portion of the bolt which extends into the recess is threaded and has screwed upon it a nut y’, the latter, when turned up on the thread, serving to press indirectly upon the shoulder z’, and by its reaction, draw the bolt and die downward, pressing and binding the latter upon the top of the base so that it cannot be turned. In order to eliminate friction of the nut upon the shoulder z’, there is interposed a series of anti-friction balls 7c, these balls being con-l tained in a groove Z in the nut, and bearing against a steel washer m on the under side of the shoulder. The balls are retained in the groove by an annular retainer in which allows the nut to be entirely removed and’ inverted if occasion requires, without danger of the balls spilling out.

The nut is wholly contained within the recess L, and in order to make it accessible so that it can be rotated, the sides of the tool are recessed so as to expose the sides of the nut. This enables the user of the tool to grasp the nut between his thumb and foreiinger and turn the same. As the nut is thus wholly contained within the periphery of the base, it affords no projecting points liable to be caught or struck accidentally, so that danger of loosening the die from this cause is avoided. It also permits the elimination of the usual external hand-wheel, which in the old type of staking tool projects considerably and affords an opportunity for the tool to be accidentally displaced and knocked about.

It is necessary to prevent displacement of the die while it is being clamped by the nut, and for that purpose I provide an element in the nature or’ a key which holds the bolt from rotation, and limits its motion to an endwise displacement. Such key element is conveniently a screw g set into the side of the base in a tapped hole which intersects the passage e’, and having a reduced end g projecting into a longitudinal groove or keyway g2 in the side of the bolt. Thus the bolt, while being permitted to move freely endwise, is prevented from turning and displacing the die when the nut j is turned. IThe engagement between the bolt and die is such that the latter may turn freely when released by loosening of the nut.

Another feature of improvement of the .staking tool is the adjustable friction by which the punch or centering tool may be retained in the head at the same distance above the die. When the head is made with an aperture sufficiently large for the tool to slide loosely through it, the latter must either be held by the workman while the die is being adjusted, or where it is necessary to use two hands in adjusting and clamping the die, the centering tool must be entirely removed and laid down to permit of this action. I have devised a scheme by which the tool may be allowed to remain in the head, and yet be held automatically high enough above the die to enable the latter to be turned, and the workman to use one hand for holding the die stationary, while the other is used to clamp it. This result is accomplished by providing the head c with an extension o which is divided by longitudinal slots p into semi-detached spring fingers. The extension constitutes a split externally tapered sleeve which is threaded on the outside and receives a clamping nut i”. This nut may be adjusted to give any amount of compression desired to the parts of the sleeve, and ordinarily is fixed so that the centering tool s or other tool which may be held in the head, can be moved up’and down easily by a slight pressure, but will be held when the workman leaves it alone.
I claim l.

A staking tool comprising a base having a passage extending from its bottom upwardly and a second passage of smaller diameter extending downwardly from its top and opening into the first passage, and having also a shoulder at the top of the first passage, a head rising from and overhanging the base, a die plate mounted on the top of the base, a threaded bolt engaged with the die, fitting the second passage and extending into the first passage, and a nut of substantially the same diameter as the first passage contained therein, threaded upon the bolt and bearing against the shoulder, the base having recesses in its opposite sides intersecting the first passage and exposing the sides of the nut.

2. A staking tool comprising a base, a head overhanging the base, a die resting on the top of the base, a locking bolt with which the die has a rotative engagement, passing from the die into the interior of the base, the latter having a recess opening from its bottom, at the top of which recess is a shoulder, a nut threaded upon the bolt and arranged to bear against such shoulder to clamp the die on the base, and a key member extending into a longitudinal groove in the bolt and engaged with the base to prevent rotation of the bolt.

3. A staking tool comprising a frame having a base with a passage through it, a recess in its lower portion and al flat shoulder between the walls of the passage and recess, a die supported on said base, a threaded bolt engaged with said die and extending through said passage into said recess, a nut having a groove screwed upon said bolt, a series of balls in such groove adapted to bear upon said shoulder to transmit binding pressure to the die, and a ball retainer attached to the nut holding the balls in the groove when the nut is removed.

4. A staking tool comprising a frame having a base with a passage through it, a recess in its lower portion and a flat shoulder between the walls of the passage and recess, a die supported on said base, a threaded bolt engaged with said die and extending through said passage into said recess, a nut screwed upon said bolt, having a groove in its face next to said shoulder and an annular shoulder rising near one of the edges of such groove, a series of balls contained in the groove, and a ring frictionally held by said shoulderl so as to project at one edge partially over the groove and the balls therein, to retain the balls when the nut is loosened.

In testimony whereof I have affixed my signature, in presence of two witnesses.
