PLIERS.

SPECIFICATION forming part of Letters Patent; No. 393,494, dated November 27, 1888.

Applica-tion filed Jannary, 188B.

To a/ZZ whom, it may concern:

Be it known that I, LEANDER E. WHIPPLE, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Pliers, of which the following is a full, clear, and exact description.

This invention relates to an improvement in wire-working tools, and more particularly to that class of tools represented in Letters Patent of the United States, No. 347,675, granted to me on the 17th day of August, 1886, consisting of a pair of pliers having each of its jaws formed to grasp the end of a wire, and

provided with the opposing grooves, through which the body of the wire passes loosely, in order that its end may be wound thereon.

This invention consists in providing such a tool or its equivalent with a clamp pivoted to one jaw and adapted to approach and engage the opposite jaw in a lateral direction.

In the accompanying drawings, Figure 1 is aperspective view of a pair of pliers with my invention applied thereto in its preferred form. Fig. 2 is a perspective view of the forward portion of the same. Fig. 3 is a modification.

Referring to the drawings, A represents a wire-fastening tool similar in construction to that represented in my Letters Patent before referred to, provided with the opposing recesses for the body of the wire, and having the inner surfaces of its jaws provided with the roughened portions between which the end of the wire is held.

B represents a threaded bolt pi voted to the lower jaw, a', of the pliers in any suitable manner, preferably by a pin, a2, iiXed in open slot in the jaw and passing through a perforation in the bolt. In the opposite jaw, a, a corresponding open slot, d, is formed large enough to admit the bolt B. e c represent lugs or projections on the upper jaw, on each side ofthe slot d. A portion of the surface of these lugs is beveled or inclined in opposite directions, and they are provided with the pins or stops e" and c, the purpose of which will hereinafter appear.

C represents a nut or handle, tapped to receive the bolt B. By threading the bolt the device is adapted for adjustment to Wires of different thicknesses. Though this is the pre- Serial No, 261,806. (No model.)

ferred form, it is not essential-as, for instance,the bolt may be smooth on itsperipheral surface, as shown in Fig. 3, with a. head, g, formed thereon. By providing the jaws with the open slots the clamp can be placed in an operative position in engagement with the jaws after the tool has been slipped over the body of the wire and its end grasped between them.

The operation of the device is as follows: The tool' being in the position shown in Fig. 2, it is slipped over the body of the wire, which is embraced within the transverse groove, and the end of the wire grasped between the roughened surfaces. The nut or handle C is then turned on the bolt until it is far enough advanced thereon to touch the upper surface of theupperjaw. Then the nut is in its proper position on the bolt, it is turned bodily on its pivot up into the slot (I, the nut passing between the lugs e and c. The nut is then turned, by which movement it is caused to ride up the inclined surfaces of the lugs, thereby powerfully compressing the jaws together upon the end of the wire in the manner of a vise. The nut is limited in its motion on the lugs c c by the stops or pins c2 c3 thereon.

While I have shown and described a construction best adapted for carrying out my invention, it is to be understood that it is susceptible of various modifications within the range of mechanical skill.

Having thus described my invention,what I claim is- 1. The wire-fastening tool provided with the clamp pivoted to one jaw and adapted to appreach and enga-ge the opposite jaw in alateral direction, whereby the clamp may be placed in an operative position subsequent to closing thejaws on the wire.

2. In a wire-fastening tool, the opposing jaws a a', the open slots therein, the bolt B, pivoted in the slot in one of said jaws and adapted to enter the slot in the opposite jaw, its operating nut or handle, and the lugs e c.

3. In a wire-fastening tool, the opposing jaws a a, the open slots therein, the threaded bolt B, pivoted in the slot in one of the jaws, and its operating nut or handle.

4. In a wire-fastening tool, the opposing jaws a a', the open slots therein, the bolt B,
