HENRY M. KULP, OF PHILADELPHIA, PENNSYLVANIA, AND oHARLEs H. LAIRD, OF CAMDEN, NEW JERSEY.

WATC'HMAKERS PLIERS.

$PEGIFIGATION forming part of Letters Patent No. 505,835, dated October 3, 1893.

Application filed May 25, 1893.

To all whom it may concern:

Be it known thatwe, HENRY M. KULP, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, and CHARLES H. LAIRD, of Camden, in the county of Camden and State of New Jersey, citizens of the United States, have invented a new and useful Watchmakers Tool, of which the following is a specification.

This invention relates to watchmakers tools which are in the shape of pliers and used in working on watch-cases for the purpose of removing or replacing the ring, pressing the ring in shape, and holding the casespring in shape or place While being adjusted, and has for its object to facilitate and make the several operations conveniently attainable by a device wherein the parts are simple and eifective in their construction and operation, strong and durable, easily handled and operated, and comparatively inexpensive in manufacture.

With this and other objects in View, the invention consists of the construction and arrangement of the parts thereof as will be hereinafter more fully described and claimed.

In the drawings: Figure l is a perspective view of the improved tool. Fig. 2 is an elevation of the tool shown applied to a ring and as spreadingthe latter open in the operation of removing or replacing the same. Fig. 3 is a similar view showing the operation of bending the ring by the improved tool to give it the proper shape. Fig. 4 is a similar view of the improved tool shown applied to the casespring to adjust the same. Fig. 5 is a front elevation of the tool showing the arrangement of the jaws.

Similar numerals of reference indicate corresponding parts in the several figures of the drawings.

Referring to the drawings, the numeral 1 designates a stationary handle, from the inner side of which project lugs 2, that extend toward each other to form a dove-tail slot 3, in which is held a pad or cushion 4 of leather or other material. The outer end of the said handle 1 is arranged as a jaw and formed with a recess 5 by removing the metal at this point, and at the outer end of the same projects laterally from one side a post 6, with an $erial No. 475,493. (No model.)

outer flange 7 that partially surrounds the same on its upper edge anda groove 8 of circular form also only partially surrounding the said post. The said post is located on the side that the recess 5 is formed, and at the base of the upper part of the said post the jaw is extended upwardly to form a bearing surface 9. In rear of the jaw the said handle 1 is formed with a recess 10 on each side of the same to receive the lower bifurcated end 11 of an elbow 12,having a slot 13 extending therethrough, and the inner edge thereof adjacent to the terminating end of the same is formed witha dove-tailed slot 14, toimmovably receive a pad 15, of leather or other analogous material. In the slot 13 of the elbow 12 is pivotally mounted a movable handle 16, which has a, dove-tailed recess 18 on the inner edge thereof to receive a pad 19, of leather or other suitable material, and which is adapted to co-act with the aforesaid pad 4, the said handle 16 being normally pressed apart at the rear by the interposition of a coiled spring 20, which movably engages the said handle 16 and is secured to the opposite handle 1. The outer end of the handle 16, beyond its pivotal point, serves as a jaw and is constructed with with the cushion or pad carried by the outer end of the elbow 12.

When it is desired to-remove a ring or adjust the same to be applied, the improved tool is arranged as shown in Fig. 2, when said operation will be greatly facilitated.

Fig. 4 shows the manner of operating on a case-spring to hold the same in place while being adjusted, and in this instance the pad carried by the elbow 12 is located on the out side of the case, and the construction of the slot or recess 21 is such as to permit the spring to be screwed in the case by passing the fas= tening through the said recesss.

As shown in Fig. 3, the pads t and 19 are adapted to be successfully used for shaping the ring, and in all instances the employment of the several pads will prevent marring of the parts with which they contact.

The advantages of the device herein set forth are manifold, and it is obviously apparent that changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the ad vantages of this invention.

It will be seen that the elbow and the two jaws are arranged in the same vertical plane, and to one side of one of the jaws so as to co-operate therewith.

Having described the invention, What is claimed as new is 1. In a watchmakers' tool, the combination of handles having jaws on their outer ends, and pads secured to the inner opposing surfaces of the same, substantially as described.

2. In a=watchmakers tool, the combination of handles having jaws on the outer ends thereof, and a stationary elbow secured to one of' said handles and carrying a pad with which one of said jaws co-acts, substantially I as described.

3. In a watohmakers tool, the combination of handles with jaws on their outer ends having recesses therein on one side thereof, and posts projecting laterally from the said jaws and provided with flanges and grooves which partially extend around the same, substantially as described.

4. In a Watchmakers tool, the combination of handles having jaws on their outer ends provided with recesses and posts, one of said jaws having a nose, a stationary elbow secured to one of said handles and supporting a pad, and oppositely-situated pads carried by the handles in rear of the jaws thereof, substantially as described.

5. A watchmakers tool, provided with pivoted handles having jaws at their outer ends, 5 the lower jaw having a laterally-extending post 6 formed with a groove 8 and a flange 7, and the upper jaw having the lateral post 22 grooved and flanged similarly to the post 6, and also provided with a shoulder 23, as set forth. I

6. The pivoted handles having co-acting jaws at their outer ends, combined with the stationary elbow secured to one of the jaws and arranged in a vertical line c'o-incident with both jaws and to one side of one of the jaws so as to co-operate therewith, as set forth.

In testimony that we claim the foregoing as our own we have hereto affixed our signa- 6o tures in the presence of two witnesses.
