Itatcnted ring. 1., 1916.

Application filed November 9,1915. Serial No. 80,537.

To aZZ whom it may concern Be it known that I, Lns'rnn Wnsroorr, a citizen of the United States, residing at Theresa, in the county of Jefferson and State of New York, have invented certain new and useful Improvements in Wrenches, and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of this invention is to provide a novel type of wrench, for removing or replacing horseshoe calks, that will be of simple constructi on, cheap to manufacture, will be durable, and of such construction that it will accommodate any size or shape of shoe calk, and can be conveniently associated with the calk.

Other objects will appear and be better understood in that embodiment of my invention of which the following is a specilication, reference being had to the accompanying drawings forming a part thereof in which Figure 1 is a side elevation of the wrench. Fig. 2 is an edge elevation thercof'showing the wrench end in section so as to disclose the operating base of one of the jaws. Fig. 3 is a transverse section taken on the line 3-3 of Fig. 1.

Referring to the drawings in detail, the

numeral 1 designates the shank of the wrench, formed preferably of soft steel or iron, and has its lower end provided with an opening 2, and its upper end provided with a frame 3. The frame 3 includes the upwardly converging side bars ll, and the upper connecting bar 5 which connects the upper ends of the converging bars 44:. as shown in Fig. 1 of the drawing. Associated with one of the sides '1 of the frame 3, is astationary jaw 6. This stationary jaw is substantially U-shaped in cross section, and has its sides lying on opposite sides of the adjacent sides 4 of the frame, and'secured thereto by means of the pin 7 which extends through the sides of the jaw 6 and through the adjacent sides a of the frame. The outer surface of the biting portion of the U-shaped jaw 6 is provided with a series of upwardly extending teeth 8.

The opposite sides elof the frame 3, have slidably associated therewith a movable'jaw 9. This movable jaw 9 is substantially U-shaped in cross section and has its sides lying on opposite sides of the said adjacent sides 4 of the frame 3, and the outer ends of the sides of the jaw extend a distance beyond the sides 4: of the frame, as shown at 10, and a pin 11 extends through alined openings in the extended portions 10 of the sides of the'jaw 9, and holds the jaw attached to the adjacent sides 4i of the frame. The biting portion of the lat-shaped jaw 9 is disposed inwardly of the frame and is providedwith a series of downwardly projecting teeth 12. The sides of the jaw 9 are of greater length than the biting portions of the jaw 9, so as to provide the upper recess 13 and the lower recess 1e.

The jaws 6 and 9 are formed preferably of hard steel so as to admit of the same withstanding considerable strain.

In use, when it is desired to tighten a calk in ahoreshoe, the wrench is so positioned that the movable jaw thereon will be on the right side of the wrench. The movable jaw 9 is then moved in the direction of the shank 1, and the jaws (3 and 9 positioned on opposite sides of the calk and the jaw 9 then moved forward so as to effect the gripping action between the calk and jaws 6 and 9, so that when the wrench is turned in the proper direction the calk will be tightened in the shoe. When removing the oalk from the shoe the *rench is turned so as to cause the movable jaw to be on the left side of the wrench and the calk then gripped between the jaws so that the same can be removed when the wrench is turned in the proper direction.

Having thus described my invention what of the frame, a movable jaw associated with jaw and slidably engaging the outer edge of 10 the other side bar of the frameand being the adjacent side bar of the frame. substantially U-shaped in cross section and In testimony whereof I aflix my signature having gripping surfacefdisposed inwardly in presence of two Witnesses.

5 of the rame, the sides o the movable jaw 7 being arranged, respectively, on the opposite LESTER WESTCOTT' sides of the adjacent side bar of the frame Witnesses: I and extending therebeyond, and a pin eX- CI-IAs G. Lnim, tending through the sides of the U-shaped FRED CHEEsMAN.
