WATCH-MAKERS AND JEWELERS PLIIERS.

SPECIFICATION forming part of Letters Patent No. 399,655, dated March 19, 1889. Application filed October 31, 1887- Serial No. 253,839. (No model.)

To all whom it may concern.-

Be it known that I, J osnrn DANIELS, a citizen of the United States, residing at Oleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Pliers; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to pliers; and the object of theinvention is to provide a tool having certain novel features, as shown in the drawings, and hereinafter described, especially adapted to do certain kinds of watchmakers and jewelers work, as well as to be of general value in making and handling watches and jewelry.

In the accompanying drawings, Figure 1 is a perspective of the pliers, showing them closed; and Fig. 2 a similar view showing the pliers open. Figs. 3 and 4 are side views taken from opposite sides. Fig. 5 is an elevation (the handles being broken elf) showing how the pliers are used in forming a notch or shoulder in a jewel-setting. Fig. 6 shows the use of the pliers in springing the flange on a watch-case. Fig. 7 shows use in setting a stone by corrugating the setting with one of the jaws.

Several distinguishing and characteristic features enter into the improvements constituting my invention, as will be readily seen in the drawings.

In the first place, the jaws a Z) are bent laterally from the joint or pivot portion, as seen in Figs. 3 and el. Then, again, theyare curved downward in the same direction when viewed from a side elevation, as seen in Fig. 5, the curvature, however, being most marked in the upper jaw, a, so that an open space is left between them until the point of the upper jaw is reached, which bears on the lower one only at its point when the pliers are closed[ In the next, place the lower jaw is made somewhat longer than the upper on 0, so that when closed the two parts will sustain about the same re lation in respect to length and position. (Most clearly seen in Fig. 1.) Both jaws terminate in sharp ends, and both ends are slightly tapered, so as to be about as much narrower than at the base of the jaws, as is shown in Figs. 3 and 4. Then, again, the lower jaw is beveled, as seen at 0, giving the said jaw a sharp edge diagonal to the line of its projection, and has two or more longitudinal grooves, (1, formed on its inner surface, Figs. 1 and 2, and terminating at its outer extremity. The upper jaw is curved round to a sharp biting end or edge, which lies across the grooves 61 when the parts are closed. By this construction pliers are provided having a variety of uses in the watch-makers and j ewelers arts not hitherto found in tools of this kind, and an article of decided utility and value is produced. A number of practical applications thereof might be cited, but a few will suffice for illustration. For example, in Fig. 5 I show how the pliers may be employed to form a shoulder on the fingers of a setting for a diamond or other precious stone, it only being necessary to extend the pliers over the finger the necessary distance, and then by giving a gentle pressure to the handle the shoulder is formed on the inside of the finger by the shorter or upper jaw, the lower extended jaw providing an extended bearing on the opposite side. In Fig. 6 I show their use in bending watch-cases which have become so worn as to need tightening in order to make them hold their seats. In this case the upper jaw serves to draw or bend the material from the top, while the longer jaw furnishes a support at exactly the right place on the under side of the case. The respective faces or sides of the jaws are finely polished, and as the material necessarily is very hard and stony the exposed polished surfaces are very convenientin burnishing the gold settings for cameos and the like. Indeed, I have found such a variety of uses for this instrument that it would be difficult to enumerate all, and others are con stantly occurring to .me as I subject it to further tests.

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

In pliers, a lower jaw having a sharp-edged end diagonal to the sides of the body part and longitudinally corrugated, an upper jaw constructed to touch the lower one only at its extremity, and both jaws curved laterally and downwardly, substantially as set forth.

JOSEPH DANIELS.
