WATCHMAKERS STAKlNG-PLIERS.

SPECIFICATION forming part of Letters Patent No. 537,382, dated April 9, 1895. Application filed February 2, 1895. Serial No. 537,038. (No model.)

To ctZZ whom it may concern: 7

Be it known that I, CHARLES C. BRANSON, residing at Granite Canon, in the county of Laramie and State of Wyoming, have in vented a new and Improved Staking-Tool, of which the following is a specification.

My invention relates to improvements in watch makers tools and it has primarily for its object to provide a simple and inexpensive tool of this kind, which can be conveniently and quickly manipulated for the purpose of staking or securing staffs or pinions to watches, and for other similar purposes.

My invention also has for its object to provide a staking tool in which the punch portion is made a permanent part of the tool.

With other minor objects in view which hereinafter will be referred to the invention consists in a staking tool constructed in the pe culiar and novel manner first described in detailand then specifically pointed outin the appended claims, reference being had to the accompanying drawings, in Which- Figure 1 is a perspective View of my improved staking tool, and Fig. 2 is a side view thereof showing the jaws and the ejecting lever disposed in a position for pushing out the staff of the wheel.

My invention in its practical form is in the nature of a pair of pliers, provided with a third or supplemental lever arm, which is adapted to serve as an ejecting lever to push the shaft after the plier jaws have been properly set in position.

Referring to the accompanying drawings, A indicates the upper jaw, B the lower jaw, and A and B the respective handle members of such jaws, which jaws and handle portions are arranged substantially like those of the ordinary jewelers pliers. Each jaw has its clamp face provided with a boss or hub like portion ab which have their contact faces so arranged, that when the jaws are closed they will close true and in a parallel plane. The upper jaw A has an aperture a which also extends through the boss at, and in such aperture is adapted to be fitted a stake 0r punch pin 0, the lower end of which is provided with the usual pin hole or concavity c to receive the new staff to be driven into the balance or other wheel. The lower boss b and jaw B are apertured as at D through which the old staff falls when pushed out of the wheel in the manner presently described.

The jaws A and B are slotted as at E and F, in which plays the upper end g of a supplemental or ejecting lever, which is pivotally connected with the upper jaw as at g and which terminates in a head portion g bent at right angles to the body and projected ove r the stake or punch member, while its handle portion 9 extends under the lower handle as clearly shown.

The manner in which my improved staking tool is used is best explained as follows: To remove the old staff, the wheel is set on the lower boss with the lower end of the staff-in the opening therein. The proper stake or punch is then fitted in the upper jaw and boss and held to engage the upper end of the staff as shown in Fig. 2. When in this position the operator closes in the handle of the supplemental lever which causes the upper end to press against the pin or stake C and in consequence punch the old shaft out of the wheel, which then drops out through the discharge opening. It will thus be seen that I provide a staking tool having all the ejecting parts connected, and such parts so arranged that the use of a hammer is entirely dispensed with.

By arranging the bosses on the jaws in the manner shown the same will hold the wheel true and prevent it from being bent.

My improved tool can also be used to straighten bent wheels or as wheel truing pliers for all wheels of a watch, to press on hair springs androller tables, and for putting in arbors and pinions in the wheels.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. A staking tool comprising a pair of plier arms, having their jaw members apertured, the upper one of which is adapted to receive the stake, and a third or supplemental plier lever having a push portion adapted to engage the stake or punch when operated, all arranged substantially as shown and for the purposes described.

2. As an improvement in watchmakers said supplemental lever is pressed inward all tools, the combination with the plier jaws A, arranged substantially as shown and de- 10 B, having apertured clamp ends, and the stake scribed. 0r punch detaehably held in the upper jaw, 5 ofthesupplementaljawGpivotallyconnected CHARLES BRANSON' to the jaw A and having an angle member WVitnesses: projected over and adapted to press down on W.
