GEORGE B. FRIDAY, 01 PITTSBUBGH,.PENNSYLVANIA.

on wanton,

Application filed June 5, 1922. Serial N0. 568,108

To all whom it may concern it Be it known that I, Gnome B. FRIDAY, a

citizen of the United States, residing at Pittsburgh, in the county of Alleghen and State of Pennsylvania,- have invente certain new and useful Improvements in Gap Wrenches, of which the following s a specification.

This invention is for a wrench, and re lates articularly tothat type of wrench used or applying and removing the caps of Mason jars and other receptacles, though it may be adapted for other uses.

The objects of the invention. are to provide a sim le eflicient wrench adjustable for use with o jects of different sizes, which is hi hi eflicient stron and which may be p g y d f After the rope has been drawn taut, the

cheaply manufacture The invention may be readily understood by reference to the accompanying drawings, in Fwhich :h t

i 1 s ows a 0 abou to be applies turned;-

Fig. 2 shows a similar view, with the wrench in grlpping relation with the cap;

Ian view of the wrench to an object to be Fig. 3 is a section on line III-III of- Fig 1;

i 4 is a transverse sectlon on line IV V of Fig. 1;

Fig. 5 is a detail view of a cam which forms part of the locking means for the flexible adjustable object engaging means of the wrench.

In the drawings, 5 represents an integral solid metal handle having an enlarged end 5. The top flat face of the enlarged end is provided with a U-shaped recess 6. Re tained in the U-shaped recess is a Y-shaped jaw 7 through the shank of which passes a suitable pin or rivet to provide a pivot for the 'aw, this rivet also passing through the ban le. The two arms 8 and 8' of the jaws are oppositely toothed along their inner edges, which are the article engaging surfaces of the jaws. As shown in Fig. 3, the thickness of the jaw is substantially the same as the depth of the recess,'so that the jaw is flush with the handle. The two sides 6" of the recess serve as stops to limit the pivotal movement of the j aw.

The jaw has a central hole passing through it at 9, and passed through the hole, is one end of a flexlble rope, preferablywire rope, or chain, 11. A zinc button 12 on the end of the rope prevents the rope from slipping through the hole. This rope may be of any suitable length. Secured to the handle below the U-shapcd recess 6 by a rivet or other suitable pin 13, is a stud or 0st 14 having a rope-engaging groove therein. Beside this stud, and pivoting about a pin 15, is an eccentric clampinn cam 16 having a rope engaging recess therein and having wings 16 thereon by means of which the cam may be turned.

In the drawings','A may designate a jar ca or other object to be turned. 11 use, the wrench is applied to the cap, as shown, with the jaws contacting with the cap. The rope 11 is then placed around the cap and the free end'lpassed between the 0st 14 and the cam 16, and drawn taut.

cam is turned in a direction to clamp the cord. Any pull on the portion of the cord passing around the 'cap will tighten the clamp, while a pull on the free end of the cord will loosen it.

After the wrench is thus applied, the handle is turned inthe direction the object Av is to be turned. When the handle; is

moved initially, jaw 7 will remain stationary. This will tend to increase the tension on the. rope about the cap, and the cap will begin to turn with the wrench. The shoulders 6. will limit the relative movement between the jaw and the handle, and prevent too great strains from being transmitted entirely through the cord.

As shown in Fig. 2, the device is applied to the cap to unscrew it. When using the wrench for screwing a cap tight, the cord is passed around the cap in the reverse direction. Thus, the relative movement between the jaw and the handle may always be utilized to tension the rope encircling the cap.

All of the movable parts are mounted on one side of the handle, which is the side turned toward the operator, so that the operator is not liable to pinch :his fingers. The wrench is simple in construction and ea to operate.

claim as my invention: 1. A wrench comprising a handle, a jaw pivotally supported at one end of the han dle, a flexib e clamping member secured at one end to the jaw, means on the handle for limitin the, plvotal movement of the jaw relative y to the handle, .a post on the handle, and an eccentric member pivotally mounted on the handle adjacent the post, said post and eccentric member providing an adjustable clamp for said flexible clamping member.

2. A wrench comprising a handle, a recess in the handle, a single jaw having two object-engaging arms pivotally mounted in the recess, the walls of the recess serving to limit. the pivotal i'novement of the jaw, a flexible clamping member connected with the jaw, and an adjustable clamp on the handle for engagement with the flexible clamping member. 3

3. A wrench COIIIPIiSiIlg' a handle, a .U-

shaped recess on one face of the handle terminating at one end of the handle, a Y- shaped jawhaving its shank pivotally supported in said recess, the sides of the recess serving to limit the pivotal -movement of an open recess formed therein at one end, a

jaw member having a portion thereof pivotally supported in the recess, and having its movement limited by the walls of the recess, a rope attached at one end to the jaw, and rope clamping means on said handle, said recess and rope clamping means being provided on the same side of the handle.

In testimony whereof I aiiix my signature.

GEORGE B. FRIDAY.
