PIPE-WRENCH.

SPECIFICATION forming part of Letters Patent No. 282,126, dated July 31, 1883.

Application filed J one 14, 1883. (No model.)

To all whom it may concern:

Be it known that I, FRANK'A. SIMONDS, a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Pipe Tongs or Wrenches; and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to pipe-tongs having a pivoted jaw and one handle.

The object and nature of my invention will appear from the subj oined description and claims, reference being had to the accompanying drawings, in which Figure 1 represents a side elevation of the device; Fig. 2, a top plan View, and Figs. 3 and 4 details.

A represents the handle, and B the pivoted The handle A is provided with a fixed jaw, a, having elevated teeth, and a concavity, a. Part of the handle and the jaw a is recessed at o to provide aspace for thepivoted jaw to move in. About midway of this space is a pivot or pin, a for the pivoted jaw. This pin may be cast with the handle, or ahole may be drilled or cast in the handle and the pin inserted afterward; but I prefer to cast the pin upon the handle, as in such a case it can be made much cheaper, especially if the pin is made with a smooth surface, which would obviate the necessity of turning it after the handle came from the mold.

The pivoted jaw B may be'made of cast or cut metal. If cast, a core is placed in the sand to leave an opening or pivot-hole, b, of about the same diameter as the pin a so that when the hole b is cleaned of the sand or drilled, it will be sufficiently large to permit of the jaw B moving freely upon its pivot.

' This hole I) is formed eccentrically upon the inserted after the jaw has been made.

object of this pin is to prevent the jaw B from passing below the handle either at the jaw a or when swung back from said jaw. If de- The sired, the pin may be made removable, for a purpose hereinafter described. The jaw B is provided with elevated teeth I) of any desired form, but preferably one of the forms shown in Fig. 3. If the pivoted jaw be made circular, teeth of diiferent forms may be placed thereon, so that it may be used for different purposes Another feature of the circular form is, that if the teeth of one part become worn, the unused teeth may be brought opposite the jaw by merely changing the side of the jawnow in contact with thehandle to the In such a case the pin b should be outside. shifted to the opposite side. If desired, a number of holes, I), may be formed in the jaw, so that the same result will be accomplished. In such a case a corresponding number of holes for pin b should also be formed in the pivoted aw.

The means for holding the pivoted jaw upon the pivot a is immaterial; but I propose in most cases to hold said jaw in place by means of a spring, 0, which also'holds the pivoted jaw close to the stationary jaw a. This spring may be of any desired form; but I prefer the form shownthat is, free at one end and passing through a loop, cso that the spring may meet the variant conditions or positions of the jaw B. The loop 0 may be cast with the jaw or made removable, and if two or more holes, I), be formed in the pivoted jaw, a corresponding number of loops may be provided; or the loop may have a corresponding number of openings in the jaw, as shown in Fig. 4. In

some cases it may be desirable to slot instead I.

of recessing the handle. I therefore do not limit myself to that particular construction.

What I claim as new is 1. In pipe -tongs, the combination of a handle having a fixed jaw, a movable jaw having stop 1), loop 0, and a spring, 0, rigidly attached by one end, and loose in loop 0 atthe other end, substantially as described.

2. In pipe-tongs, a disk having a number of holes, 0, for pins 2;, and the loops, and a spring, 0, substantially as described.-

' In testimony whereof I affix my signature in presence of two witnesses. I

FRAN K ARTHUR SIMONDS.
