JEWELERS TOOL.

Specification of Letters Patent.

Patented Aug. 15, 1905.

Application iiled May 10, 1905. Serial Nie. 259.712-

To all whom it may concern,.-

Beit known thatI, ELZIE O. OHAMBERLIN, a citizen of the United States, residing at Denison,in the county of Crawford and State of Iowa,have invented a new and useful Jewelers Tool, of which the following is aspeciiication.

This invention relates to jewelers tools, and has for its object to provide a novel form of pliers wherein the jaws are constructed and arranged for convenience in bending the prongs of a set-ring snugly about the set in a simple and effective manner with little or no liability of the set becoming broken. It is furthermore designed to arrange one of the jaws of the pliers for use as an anvil to support the ring and to shape its jaws so as to enable the convenient turning of the ring thereon to permit of the other jaw having access to the several prongs of the ring and at the same time to prevent slipping of the ring upon the pliers.

ith these and other objects in view the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the invention. t

In the accompanying drawings, Figure l is a perspective View illustrating one of the pli ers of the present invention in the act of bending the top end of a prong down upon theset. Fig. 2 is detail perspective view of the lower or anvil jaw of the pliers. Fig. 3 is a detail plan view of said jaw. Fig. 4 is a perspective view ofthe upper jaw, which constitutes a die. Fig. 5 is an inverted plan view of the upper jaw. Fig. 6 is a detail cross-sectional View of the lower or anvil jaw of the tool.

Like characters of reference designate corresponding parts in each and every iigure of the drawings.

The present tool is made up of a pair of handle members 1 and 2, which are crossed and provided at their points of crossing with the respective bearing-eyes 3 and 4, that are pierced by a pivotal connection 5, whereby the plier members are pivotally connected in the usual manner. The lower jaw 6 of the upper handle member 1 projects beyond the upper jaw 7 and its upper face is provided With a lining 8 of suitable soft material, preferably brass. Each side of this lower jaw 6 1s provided with a concaved seat 9, which extends into the inner or upper face of the jaw,

.tudinal groove there are transverse grooves 11, all of the grooves intersecting the respective outer edges of the jaw.

In using the tool or implement as shown in Fig. 1 the lower jaw or anvil 6 is placed within a ring 12 at the under sideof the seat for the .reception of the set 13, which is formed by the usual prongs 14, after which the handles are drawn together so as to press the jaw 7 against the side-of one of the prongs, so as to force the latter against the edge of the set, this operation being repeated until all of the prongs have been pressed against the set. It

will now be understood that the opposite sides of the lower anvil-jaw 6 are provided with concaved seats leading to the inner or upper face of the jaw to permit turning of the ring upon the lower jaw to give the upper jaw access to all of the prongs, the face of the lower jaw being lined with some soft metal to prevent scratching of the ring. After the prongs have been .forced laterally against the edge of the set the ring is brought into a position at substantially right angles to the lower jaw and the tip ends of the prongs are bent down over the top of the set by means of the outer extremity of the upper jaw 7. In pressing down the extremities ofthe prongs each prong is received within the longitudinal groove or channel 10 of the upper jaw and the entire tool removed or slid slightly toward the set, which ei'ectually upsets or bends the extremity of the prong without liability of the tool slip ping therefrom. The side grooves or channels 11 are intended for the same purpose where it is impossible to engage a prong with the groove 10.

From the foregoing description it will be understood that the tool of the present invention is exceedingly simple and effective for the purpose designed and may be conveniently handled Without requiring any particular deof the jaw, and the other jaw terminating short of the first-mentioned jaw and formed t0 bear against the prongs of set-rings.

2. A tool of the character described comprising crossed pivotally-connected handles terminating in cooperating jaws, one of the jaws having its inner face concaved longitudinally and convexed transversely, the opposite sides of the jaw being provided with concaved seats merging into the inner face of the jaw, and the other jaw being terminated short of the first-mentioned jaw and formed for engagement with the prongs of set-rings.

3. A tool of the character described comprising a pair of crossed pivotally-connected handle members terminating in jaws, one jaw being longer than the other and provided upon its inner face with a lining of soft metal, said inner face of the jaw being concaved longitudinally and convexed transversely, opposite sides ofthe jaw being provided with concavedseats merging into the inner face of the jaw,

and the other jaw being provided in its inner face with a longitudinal groove intersecting its outer end, and transverse grooves located at opposite sides of the longitudinal groove and intersecting opposite sides of the jaw.

ln testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
