Specification of Letters Patent.
Patented Nov. 21, 1905.
Application filed July 1'7, 1905. Serial No, 270,029.
To aZZ whom it may concern;
Be it known that I, CHARLES E. CUNNIUs, a citizen of the United States, residing at Freeland, in the county of Luzerne and State of Pennsylvania, have invented a new and useful WVrench, of which the following is a specification.
My invention relates to wrenches, and while especially useful and desirable as a pipe-wrench may be used with satisfactory results for any other purpose for which a wrench is ordinarily used.
It is well known that in the use of pipewrenches the wrench will be used sometimes for many successive days upon the same sized pipe, and when the desired adjustment has been secured it is desirable to maintain such adjustment so long as the wrench is being used upon the same size of pipe.
It is the object of my invention to provide a wrench which may be adjusted to any desired size of work-receiving opening and when so adjusted will remain set until the adjustment is intentionally changed.
WVith thisand other objects in View the present invention consists in the combination and arrangement of parts, as will be hereinafter fully described, shown in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes inform, proportion, size, and minor details may be resorted to without departing from the spirit or sacrificing any of its advantages.
In the accompanying drawings, Figure 1 is a perspective view of my improved wrench. Fig. 2 is a longitudinal sectional view of my improved wrench. Fig. 3 is a transverse sectional view of my improved wrench, taken on line 3 3 of Fig. 2. Fig. 4 is a perspective view of the latch of my improved wrench.
Like characters of reference designate corresponding parts throughout the several vlews.
My improved wrench comprises an elongated rigid handle member 1, having one end formed into a transverselydisposed workengagin face 2. Upon the handle 1 and adj acent the face 2 is pivoted the block 3 by means of the pivot-pin 4. The block 3 is provided with a longitudinal screw-threaded opening 5. A jaw member 6 is provided with a work-engaging face 7, arranged for cooper-v ation with the face 2, and is formed integral with the screw-threaded shank 8. The shank and proportioned to clamp the parallel sides 9 of the shank and prevent rotary displacement.
The operation of my improved wrench is as follows: The latch 10 is disengaged from the shank and the jaw 6 rotated in either direction until the desired work-receiving aperture is obtained, after which the latch is clamped about the shank, which will prevent rotary displacement and chan e of adjustment of the jaw until intentionaTly released.
Having thus described the invention, What is claimed is 1. A wrench comprising a handle provided with a work-engaging face, a block pivoted upon the handle, a jaw member having a shank passing through the block and a latch carried by the block and arranged to embrace the shank.
2. A wrench comprising a handle provided with a transversely-disposed work-engaging face, a block pivoted upon the handle, a jaw member having a shank passing throlwh the block and a latch carried by the block and arran ed to embrace the shank.
3. wrench comprising a handle provided with a work-engaging face, a block pivoted. upon the handle, a jaw member having a shank passing through the block and a latch pivoted to the block and arranged to embrace the shank.
4. A wrench comprising ahandle, provided with a Work-engaging face, a block pivoted. upon the handle and provided with an opening, a member having a shank passing through the block and provided with parallel sides, a latch pivoted upon the block and provided with a bifurcated clamp member arranged to clamp upon opposite parallel sides of the shank.
5. A wrench comprising a handle provided with a transversely-disposed work-en aging face, a block pivoted upon the handle and provided with an o ening, a jaw member provided with a wor -engaging face and a shank having angular sides and disposed within the opening of the block and a latch member pivoted to the block and having a bifurcated angular portion arranged to clamp upon the parallel sides of the jaw shank.
6. A wrench comprising a handle provided with a transverse work engaging face, a
block pivoted to the handle and provided and provided with a screw-threaded shank with parallel flattened sides interrupting the screw-threads and engaged Within the screwthreaded opening of the block, a latch member pivoted to the block and provided with an angularly-disposed bifurcated portion arranged to clasp the parallel sides of the jawshank to prevent rotary displacement of the aw.
In testimony that I claim the foregoing as my own I have hereto afiixed my signature in the presence of two witnesses.
