United States Patent Glice PIPE WRENCH WITH COOPERATING SLIDABLE JAW AND FLEXIBLE PIPE HOLDING MEANS Fredrick D. Stover, Sr., Coalgate, Okla. Application March 6, 1956, Serial No. 569,888 1 Claim. (Cl. 8164) The present invention relates to new and useful improvements in wrenches adapted for gripping pipes or other curved objects.

An important object of the invention is to provide a slidable V-shaped jaw against which a pipe is held by a cable or other suitable llexible member and actuating the jaw by a pivoted handle to move the latter against the holding action of the cable to elfectively clamp the pipe against the jaw.

Another object of the invention is to provide a wrench of this character in which a pipe-embracing cable is employed and equipped with adjusting means to easily and quickly provide an approximate pipe-clamping adjustment and wherein the cable is tightened about the pipe by a pivoted handle operating against a sliding jaw in a manner tending to constrict the cable.

A further object is to provide a device of this character of simple and practical construction, which is etlicient and reliable in operation, relatively inexpensive to manufacture, and otherwise well adapted for the purposes for which the same is intended.

'These, together with other objects and advantages which will become subsequently apparent, reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure l is a side elevational view;

Figure 2 is a side elevational view taken at right angles to Figure l;

Figure 3 is an an enlarged transverse sectional view taken on a line 3 3 of Figure l;

Figure 4 is an enlarged fragmentary longitudinal sectional vew taken on a line 4 4 of Figure 2.

Figure 5 is an enlarged perspective view of the guide at the front end of the stationary handle for the sliding Jaw;

Figure 6 is an enlarged perspective view of the cable anchoring member; and

Figure 7 is an enlarged perspective view of the slidable jaw.

Referring now to the drawings in detail, wherein, for the purpose of illustration, I have disclosed a preferred embodiment of the invention, the numeral 5 designates a stationary handle having a head 6 formed at its front end and composed of a pair of laterally projecting spaced apart parallel plates 7 and 8 forming a guide slot 9 between the plates for the shank portion 10 of a V-shaped slidable jaw 11.

The shank 10 of the jaw is slidably retained in the slot 9 by a filler member 12 which is secured between the plates 7 and 3 at their outer edge portions by rivets or other suitable fastening means 13. The ller member 12 is formed with a downwardly extending apertured ear 14 which is pivoted in the bifurcated upper end portion 15 of a pivoted handle 16' by a transverse pin 17 for swinging the handle 16 toward and away from the stationary handle 5.

A roller 18 is rotatably mounted in the bifurcated upper end portion 15 of handle 16' for engaging the inclined lower end 19 of the shank 10 of sliding jaw 11. A coil l 2,834,238 Patented May 13, 1958 spring 20 connects the shank 10 of sliding jaw 11 to the stationary handle 5 to retract the sliding jaw.

The upper portion of the filler member 12 is formed with a slot 21 leading to a chamber 22 in the liller member to receive a ball or other diametrically enlarged member 23 at one end of a cable 24. The ball 23 is retained in the chamber 22 by a screw 25 which closes the outer end of the chamber. The cable 24 extends upwardly through a vertical slot 26 at one side edge of sliding jaw 11 and over a pipe 27 positioned in a toothed V-shaped notch 28 at the outer end of the jaw and the cable then extends downwardly to a vertical slot 29 at the opposite side edge of jaw 11 to enter a vertical slot 30 at the outer or rear edge of stationary handle 5. The slot 30 is formed with longitudinally spaced apart pockets 31 adapted to selectively receive balls or other suitably diametrically enlarged members 32 which are secured in longitudinally spaced apart relation on the free end portion of the cable 24.

In the operation of the device, the pivoted handle 16 is moved outwardly with respect to stationary handle 5 and spring 2t) retracts the sliding jaw 11. The pipe 27 or other round work is then` placed in the V-shaped notch 28 of the sliding jaw 11 and the free end of the cable 24 is then placed across the top of the pipe and the balls 32 engaged in selected pockets 31 to hold the pipe in position on the jaw. The pivoted handle 16 is then swung inwardly toward the stationary handle 5 whereby the roller 18 will engage the lower or inner end of shank 10 of jaw 11 and force the jaw outwardly against the holding action of the cable 24 to thus tighten the gripping action of the cable and jaw.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modilications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the appended claim.

What is claimed as new is as follows:

A wrench comprising a stationary handle having a head at one end and at one side thereof formed with a slot, a ller member fixed in said slot, a slidable jaw having a shank slidably fitted in the slot between the stationary handle and the filler member for sliding of said slidable jaw outwardly and inwardly of said end of the stationary handle, a second handle pivoted to said ller member for movement toward and from the stationary handle, a flexible member adapted to embrace work positioned against the slidable jaw and having one end fixed in said filler member, pockets in the other side of the stationary handle spaced along the same, said flexible member interlocking with selected pockets to adjust the flexible member into engaging relation to work positioned against the slidable jaw, anda roller on the second handle working in said slot against said shank to move said slidable jaw outwardly in response to movement of said second handle toward the stationary handle whereby to tighten the exible member against the work.
