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.
