COMPOUND TOOL FOR VJ'ATCHMAKERS.

Specification of Letters Patent. Patented A g- 1921 Application filed May 6, 1921. Serial No. 467,334.

To all whom it. mag concern:

Be it known that I, ABRAHAM BRILLIANT, a citizen of Russia, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Compound Tools for Natchmakers, of which the following is a specifi- This invention has for its object to provide a compound tool of the pliers type, whereby a watch-maker or repairer may remove var'- ous component parts of a watch movement, said parts including the balance roller, the hands, the hair spring stud, and anyof the jewels, without liability of injury to any part, all the elements employed in performing said operations being contained in. a single tool, so that the inconvenience of employing a plurality'of independent tools is avoided.

The invention is embodied in the improvements which I will now proceed to describe and claim. 1

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

I connectby a pin or pivot 14, two crossed levers to form-atool of the pliers type, having relatively short operating arms 12 and 18, and longer arms 12 and 13*, forming handles. The arm 12 is shorter than the arm 13, and is provided with laterally proecting ears 15. Two jaws 16 are connected wlth said cars by pivots 17, at right angles with the lever-connecting pivot 14, the jaws being adapted to swing toward and from each other in a plane at right angles tothe path in which the arms 12 and 18 swing The'jaws 16 are normally closed against each other, as shown by Fig.3, by a spring "19, which is .preferably a bent wire passed through a hole drilled through the pivot 14, and having hooked ends engaged with holes 20 in the jaws. Arms 21 formed on the jaws provide means whereby the aws may be opened, as shown by Fig. 4. Each jaw 16 has a reduced inner edge 22, abutting against a similar edge on the other jaw when the jaws are closed, and a flat upper face 23, the upper faces of the two jaws collectively forming a seat for the roller. 24 on a balance staff 25, as shown by Fig. 10, a seat for the hub portion 26 of a watch hand 27, as shown by Fig. 12, a seat for the portion 28 of a balance cock which receives the hair spring stud 29, as shown by Fig. 14, and a seat for abridge 30 containing a jewel 31, as shown by Fig. 16, the bridge here shown being the bottom bridge containing a jewel which constitutes abearing for the balance staff. The jaw edges 22 are provided with notches 22, forming an orifice, adapted to receive the arbor of the seconds hand of a watch when the jaws are closed, as shown by Fig. 3. The

jaws are, therefore, adapted for use in re moving the seconds handby a prying action.

The longer operating arm 13 is provided with two post-receiving sockets 32 and 33 (Fig. 2), and with set screws 34, adapted to secure posts in said sockets. The socket 32 is nearer the pivot 14 than the socket 33, and the arrangement is such that the inner socket 32 is adapted to hold a post 35 cooperating with the jaws in. removing a roller 24, and a hand 27. The socket'32 is also adapted to hold a post 36 cooperating with the jaws in removing a jewel 31. Each post is adapted to be secured in either socket, the outer socket 33 being employed to hold the post 35 when the latter is used for removing a hair spring stud in a Swiss watch. The outer socket is also employed to hold either post which is not in use. This will be understood by reference to Figs. 1 and 1.

The post 35 is reversible and provided with reduced end portions 35 and 35". The portion 35 is socketed to engage the balance stall 25 (Fig. 10), and the portion 35 forms a pin, adapted to bear on a center wheel post 38 (Fig. 12), and on a hair spring stud 29 (Fig. 14). When the socketed portion 35 is in use, the post 35 is secured in the inner socket 32, and when. the pin portion 35 is in use, the post 35 is secured in the outer socket 33, as shown by Fig. 1

The post 36 is used only in removing a jewel 31. This post is partially divided to form normally diverging spring fingers 36 which are reduced to form an acting end of variable diameter, adapted to bear on a jewel, the diameter of the acting end depending on the size of the jewel. The post is provided with a movable collar 40, frictionally engaged with the fingers 36 and adapted to maintain the said acting end at the desired diameter. When a relatively large jewel is to be removed, the collar 40 is raised, as shown by full lines in Fig.8. Downward movement of the collar contracts the acting end, as indicated by dotted lines.

The operating arms 12 and 13 are normally forced apart by a spring 41, engaged with the handle arms. The tool may be operated by placing the jaws in either of the positions shown by Figs. 10, 12, 14 and 16, while the arms 12 and 13 are spread apart,

and then suitably decreasing the distance between said arms to cause the acting post to coiiperate with the jaws in removing either a roller,'the hour and minute hands, a hair spring stud, or a jewel. The removal of the seconds hand may be accomplished by the jaws alone, without the cooperation of a post therewith.

Fig. 17 shows the arm 13 bent so that its outer portion is more nearly parallel with the arm 12, when the arms are fully separated, than in the arrangement shown by Fig. 1, the bent form shown by Fig. 17 being preferable.

Fig. also shows amodified construction operating armlandra longer handle arm, one

of said operating arms being shorter than the other, a pair of spring-closed jaws connected with the shorter operating arm by pivots at right angles with the lever-connecting pivot, and provided with means whereby they may be manually opened, the jaws having thin notched meeting portions collectively forming a seat, adapted to bear on either a watch balance roller, a watch hand, a jewel h0ld'er, or a hair spring stud holder, the longer arm being provided with a post-receiving socket, and with means for detachably securing a post therein, and two interchangeable posts, each adapted to be secured in said socket, and to cooperate as described, with said jaws, one post being formed to act in removing a roller, hands, and a hair spring stud, and the other post being formed to act in removing a jewel, the tool being provided with means for holding either post in an inoperative position. i

'2. A. watch-makers tool comprising a pair of crossed levers; a transverse pivot connecting said levers, each lever having an operating arm and a longer handle arm, one of said operating arms being shorter than the other, a pair of spring-closed jaws connected with the shorter operating arm by pivots at right angles with the lever-connecting pivot, and provided with means whereby they may be manually opened, the jaws having thin notched meeting portions collectively forming a seat, adapted to bear on eithera watch 110 balance roller, a watch hand, a jewel holder, or a hair spring stud holder, the longerarm being provided with two sockets'at different distances from the lever-connecting pivot, and with set screws adapted to confine posts 115 in said sockets, and two posts, each insertible in either socket, one of said posts being adapted to cooperate with said jaws in removing a roller, a watch hand, and a hair spring stud, and the other post being adapt- 120 ed to cooperate with the jaws in removing a jewel. I

3. A watch-makers tool substantially. as specified by claim 1, one of said posts being reversible, and provided with reduced end 125 portions, one of which is socketed to engage a balance staff, the other constitutinga. pin, adapted to bear on; a center staff and on a hair spring stud holder.

4. A watch-makers tool substantially as 180 specified by claim 1, the jewel-removing post being partially divided to form normally diverging spring fingers forming an acting end of variable diameter, and provided With a movable collar frictionally engaged with said fingers, and adapted to maintain the said acting end at the desired diameter.

5. A Watch-makers tool substantially as specified by claim 1, the jewel-removing post being slotted to form spring fingers form- 10 In testimony whereof I have aflixed my 15 signature.
