GLAUID E. QUIER, OF PRINCETON, OREGON.

res

WRENCH.

Application filed July 12, 1922. Serial No. 574,424.

To all whom it may concern Be it known that I, GLAon E. QUIER, a citizen of the United States residing at Princeton, in the county of -arney and State of Oregon, have invented new and useful Improvements in Trenches, of which the following is a specification.

This invention relates to improvements in wrenches and has for its principal object to provide a wrench having a handle with an enlarged toothed head and a stationary jaw consisting of a pair of plates which are pivotally connected to said head and a movable jaw comprising a toothed rack bar which is adapted to slide between the plates forming the stationary jaw and co-engage with the serrated or toothed head of the handle.

Another object of the invention is to provide a wrench having a slotted movable jaw with curved shoulders provided beneath the slot portions to engage the curved portion of the plates which form the stationary jaw, and said movable jaw may be moved to either side of the enlarged head of the handle.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts. to be hereinafter fully described illustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing my invention in detail ref erence will be had to the accompanying drawin s wherein like characters of reference denote like or corresponding parts in the several views, and in which Figure l is a side elevation of the inven tion.

Figure 2 is a front view thereof.

Figure 3 is a top plan view.

Figure 4: is a sectional view showing the relation of the toothed head with the slidable jaw.

Referring now to the drawings wherein like characters of reference denote like or corresponding parts 1 indicates a handle having an enlarged arcuate shaped head 2 which has spaced transverse teeth 3 formed on the periphery thereof and an opening a formed centrally of said head. A stationary jaw 5 consisting of a pair of spaced substantially T-shaped plates 6 which are pivotally connected together as at 7 by means of a pivot pin 8 which passes through openings 9 formed in the plates and through i the opening formed in the head. A movable jaw 10 has an extension 11 formed integrally therewith which has spaced transverse teeth 12 provided on the under face thereof, said movable jaw has slots 13 formed on each side thereof to receive the plates forming the stationary jaw. A curved shoulder 14 is formed on each side of the movable jaw directly beneath the slotted portion thereof and is adapted to engage the curved portion 14 of the plates forming the stationary jaw. The movable jaw may be moved transversely of the enlarged head to either side thereof for gripping and tightening an object.

From the above it will be seen that when the user of the device wishesto grip and tighten an object he adjusts the movable jaw with respect to the stationary jaw to fit such object and oscillates the handle of the wrench in either direction desired, that is, in the direction necessary for tightening an object.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of they several parts, provided that such changes fall within the scope of the appended claim.

What I claim is A wrench of the character described comprising an enlarged arcuate shaped head formed on the handle thereof, a pair of spaced cooperating substantially T-shaped plates providing a jaw and being pivotally secured at one end upon the opposite sides of the head, a curved portion formed on one side wall OI each T-shaped plate at the juncture of their respective portions, a slidable jaw member having a groove formed on each side wall thereof for slidably receiving a portion of the plates, a curved shoulder formed in the lower wall of each groove for operative engagement with the curved portion of the plates whereby close association ofthe slidable jaw with the first mentioned jaws is provided and a toothed extension formed on the slidable jaw for operative engagement with the teeth of the head.

In testimony whereof I afiix my signature.

CLAUD E. QUIER.
