.IMPRQVEMENT IN PLiERs..

Specification forming part of Letters Patent No. 181,175-, dated Augustl, 1876; application led 'June 3, 1876. v

T0 all whom it may concern: l

Be it known that I, WILLIAM P. HUNTooN, of Stuart, in the county of Guthrie and State of Iowa, have invented an Improved Pliers for Watchmakers and Jewelers Use, ot' which the following is a specification:

` The object ot' my invention is to provide a" tool that can be advantageously used as a pliers, and also as a vise in removing, tting, and handling-watch-hands and other small parts of delicate machinery. It consistsin forming vertical, and longitudinal intersectintersectingand crossing the vertical grooves.

c b c. The grooves a. b are smallest at the bottom, and iiare and enlarge toward the top, as required, for the free passage of broachingtools. These vertical grooves vary in size, and a graduated series, varying in number, may be uniform in each jaw. y

'Ihe groove c is straight and uniform in size from top to bottom, as required, to gripe and hold pins, screws, and similarl small and straight parts. A graduated series of these straight vertical grooves are designed to be formed in each jaw between the Haring grooves. c

These grooves and cavities a b c d may be formed by milling, or by vmeans of dies, or in any suitable way that well-tempered grooved jaws can be produced. v

Ihe size of the pliers and their jaws and grooves mayvary, as desired.

In the practical operation and test of Athe utility of my invention, take the pliers in the hand and open the jaws to admit the disk or flange of the hour or minute hand of a watch into the longitudinal groove d intersecting the vertical groove a, and then close the jaws.

By thus using my combination-tool as a pliers, you can readily seize and remove or pick up a watch-hand, and then retain it, as in a vise, to broach and tit it to its post, by simplyturning your hand and inverting the jaws and the watch-hand. While thus inverted you can pass a tapering tile, or any suitable broaching-tool, through the watch-hand to enit in iiling and fitting it in its place on the` post.

The second-hand of a watch can be readily manipulated in the same manner by means of the smallerv groove b and its intersecting groove d.

J ewel-plates, ratohets, collets, and similarsmall perforated parts ot' delicate machinery can be advantageously manipulated in a similar manner by means ot my improved tool.

I ,fam aware that pinchers and jaw-tools have been bent, and their jawsserrated and grooved; but I claim that my manner ofl intcrsecting at right angles a series of Haring or conical vertical grooves with couoidal longi-Y tudinal cavities or grooves in the jaws of bent pliers, to adapt them for the alternate and simultaneous uses of a pliers and vise, is novel and greatly advantageous.

I am also aware that straight vertical g grooves are common in jaw-toolsl for holding pins, screws, Snc.; but I claim that mytool, having a series of intersecting grooves, a d, for handling and holding perforated and diskform articles, and also a series of straight vertical intervening grooves -for hand ling and UNITED Sir-Aras PATENT .substantially as and for 'the and described. 2. As a new combination-too1, the bent pli- Awholdingf straight pins and similar small objects, is a new and convenient combinationtool.

I claim as my invention- 1. In bent pliers, the vertical andhr-zlonicalf grooves or cavities a b, intersected by the longitudinal and colloidal grooves or cavitiesd d; purposes shown ers, havingA a graduated "series of intersecting* grooves, a, d and b d, and also a l graduated' series of vertical straight grooves, 0, substantially as and for the purposes shown and described.
