ELIEEB HARVEY FRIDLEY, OF BELLEFONTAINE, OHIO.

' WRENCH.

Application filed April 18,

To all whom may concern:

Be it known that 1, Emma H. FRIDLEY, a citizen of the United States, residing at Bellefontaine, in the county of Logan 5 State of Ohio, have invented new user'ul Improvements in "Wrenches, oi: which the following is a specification.

This invention relates to wrenches, and has for its primary objects, the provision ot 1 a wrench of the quick adjusting type, wherein the movable jaw can be quickly and eas ly adjusted upon the shank of the wrench with relation to the fixed jaw and held fined relatively to the shank in its given position.

More specifically stated, the invention provides a wrench wherein the movable aw is of novel construction and equipped with means which cooperates with the shank ot the wrench to permit of a quick adjustment of said jaw, and to subsequently hold the jaw in its given position.

The nature and advantages of the invention will be better understood when the following detailed description is read in connection with the accompanying drawing, the invention residing in the construction, combination, and arrangement of parts as claimed.

In the drawing forming a part or this application, like numerals of reference indicate similar parts in the several views, and wherein Figure 1 is a constructed in invention.

Figure 2 is a rear edge elevation.

Figure 3 is a sectional view taken 3 3 of Figure 1. c

Figure 41 is a detail View, partly in oi. the movable jaw.

Figure 5 is a. bottom plan view of justing nut.

Referring to the drawing in detail, mdicates the shank of the wrench at one end of? which is arranged the fixed jaw 11. The shank has a straight edge 12, while the opposite edge from the point 13 is inclined in the direction of the fixed jaw 11 and serrated or roughened as at 1 11. At each side of the shank, I provide a narrow strip 15 which constitutes guides for the movable jaw to be presently described. These strips 5 may be secured to the shank in any suitable manner, but ii? desired they ma 'l Ol'lll 5.? an integral part of the shank.

The movable jaw is indicated at 16, and

formed with side plates or members 17 which slidably embrace the shank 10, the inner surface of each plate being recessed as at 18 to receive the adjacent strip 15, the latter as above stated, constituting guides for the movable jaw. Projecting from each plate is one part 1901'" a threaded stem 20, the latter being slotted to slidably receive the shank 10. The member 19 is Provided with a cap-like member 19 which is held associated with the member 19 by means oi a pin 20 passed through said parts as shown. in Figure ,3. Threadedly associated with the stem is a knurled nut 21. on one side of which is formed a head or rib 22 adapted to engage the serrations 14': of the shank to hold the fixed jaw immovably positioned upon the shank. In practice, it is only necessary to loosen the nut and subsequently slide the movable jaw upon the shank to its desired position, and then by tightening the nut so that the rib 21 engages the serrations 14 the jaw is held fixed relatively to the shank 10. The invent-ion is very simple in construction, and can be manufactured and sold at a very nominal cost.

l vhile it is believed that from the fore going description, the nature and advantages of the invention will be readily apparent, I desire to have it understood that I do not limit myself to what is hereinshown and described, and that such changes may be resorted to when desired as fall within the scope of what isclaimed.

What I claim is 1. A wrench including a shank, a fixed jaw at one end thereof, a movable jaw slidable upon the shank, one edge of the shank being serrated, a threaded sten'i embracing said shank and connected with said movable jaw, a nut threaded on said shank, and a rib formed on one side oi the nut and adapted to engage said serrations for the purpose specified.

2. A wrench comprising a shank, a fixed jaw at one end thereof, one edge of sair shank being serrated, a movable jaw slidable on the shank, cooperating means on said shank and movable jaw to guide the latter in its movements, a threaded stem bifurcated to embrace said shank and connected with said movable aw, a nut threaded on said stem, and an annular bead formed on one side 0-; the nut and adapted to engage said serrations for the purpose specified.

:5. A wrench comprising a shank, a. fixed said shank and including opposed members,-

said members being recessed to receive said strips, a threaded stem embracing said shank! and connnected With said opposed members of the movable jaw, and a nut threaded on said stem and cooperating with the shank to hold the shank.
