WRENCH.
Patented Oct. 26,1886.
TJVESSES a W p .zlttorneys UNITED STATES PATENT @rrrcn.
I FRANK G. SAWHILL, OF MIDWAY, PENNSYLVANIA.
WRENCH.
SPECIFICATION forming part of Letters Patent No. 351,656, dated October 26, 18 6.
Application filed August13,1886. Serial No. 210,803. (Modeh) citizen of the United States, and a resident of Midway, in the county of Washington and State of Pennsylvania, have invented certain new and useful Improvements in Wrenches; 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 whichit appertains to make and use the same, reference being had to the accompanying drawings,which form a part of this specification, and in which Figure l is a side view of. my improved wrench. Fig. 2 isa similar view of the wrench, showing it adapted to be used for clamping round articles. Fig. 3 is a longitudinal sectional View of the wrenchas shown in Fig. 1, and Fig. 4 is a similar view of the wrench as shown in Fig. 2.
Similar letters of reference indicate corresponding parts in all the figures.
My invention has relation to wrenches havinga jaw sliding uponthe shank of arigid jaw, and having an auxiliary serratedjaw for clamping round articles adapted to be placed at one of the other jaws of the wrench; and it consists in the improved construction and combination of parts of such a wrench, as hereinafter more fully described and claimed.
with a longitudinal recess, E, and a pivoted.
auxiliary jaw, F, is pivoted in the outer end of the recess at the rigid j aw,l aving itssmooth face flush with the edges of the recess, and having a serrated and rounded concave inner face. G. The inner end of the shank of the rigid jaw is formed with two perforated lips, H, between which the perforated reduced end I ofthe handle J is pivoted upon a pin, K, the
said handle having concave shoulders L L at handle, and at the inner end of this recess are formed two perforated ears, N,between which the slightly-bent lever O, which operates the sliding j aw, is pivoted at its bend, a removable pin, 1?, passingthrough the ears and the lever. The handle end of this lever may be tilted to rest in the groove or recess of the handle, and the other end of the lever is reduced and perforated and pivoted upon a pin,Q, in a slot or recess, R, in the movable jaw. The distance between the pins P and Q being greater than that between the pins P and K causes the pins Q and K to lie in different transverse planes, and provides for the easy and ready manipulation of the jaws. It will now be seen that the shank of the rigid jaw being pivoted at its inner end, the sliding jaw may be slid outward upon the shank by tilting the handle end of the operating-lever toward the handle, while by tilting the said end from the handle the jaw wiilbe slid toward the pivotal point of the shaiilgopeningthe jaws, the shank tilting in the direction of the jaws when closed, and from the direction of thej aws when opened. It will thus be seen that nuts or other articles may be clamped by the jaws, and that by drawing upon the-lever of the slidingjaw the said jaw will be forced against the'article.
The wrench may be adapted to fit a nut or other article of any size, as the sliding jaw may be moved in both directions upon the shank of the rigidjaw.
WVhen the wrench is to be used with a pipe or similar round object, the pivotal pin for the operatinglever is removed audtheslidingjaw is slid inward until the free end of the pivoted serrated jaw is uncovered, when the said jaw may be tilted upward and will rest against the inner face of the rigid jaw, forming a serrated and concave jaw, which will bite against any round article.
The sliding jaw has preferably a serrated face for the purpose of allowing it to bite into round objects as well as the pivoted jaw.
, Having thus described my invention,l claim and desire to secure by Letters Patent of the United States- 1. In a wrench, the combination of ahandle, a rigid jaw having a shank pivoted to the end of the handle, a movable jaw sliding upon the die, the pivotal point of the sliding jaw and bent lever and that of the rigid jaw and handle being in different transverse planes, as and for the purpose shown and set forth.
2. In a wrench, the combination of a handle havinga longitudinal groove orrecess and two perforated ears at the inner end of the groovea rigid jaw having the inner end pivoted to the end of the handle, a movable jaw having'a stirrup at its inner end sliding upon the shank of the rigid jaw, and having a slot or recess in its outer face, and a slightly-bentlever pivoted at the bend between the perforated ears, and having its handle end fitting in the groove of the handle, and having its outer end reduced and perforated, and pivoted in the slot or recess in the sliding jaw, as and for the purpose shown and set forth.
3. In a wrench, the combination of a rigid jaw having a longitudinal groove or recess in its shank, a movable jaw sliding upon the shank of the rigidjaw, and ajaw pivoted with its in ner end in the groove at the rigid jaw and having its smooth face flush with the edges of the recess 01' groove,and having its inner face concave and serrated, as and for the purpose shown and set forth.
4. In a wrench, the combination of a handle, a rigid jaw having the end of its shank pivoted to the end of the handle and provided in its inner face with a longitudi ual recess 01' groove, an auxiliary jaw pivoted with one end in the outer end of the groove and having its smooth side flush with the sideof the shank and its inner face concave and serrated, a jaw sliding with its inner stirrnped end upon the shank of the rigid jaw, and a slightly-bent lever pivoted at its bend upon the side of the handle and having one end pivoted to the sliding jaw, as and for the purpose shown and set forth.
In testimony that I claim the foregoing my own I have hereunto affixed my signature in presence of two witnesses.
FRANK G. SAVVHILL.
