RICHARD DENNIE HILL, OF WICI'IITA FALLS, TEXAS, ASSIGNOR, TO E. B. ZITTEL, F
' BURKBURNETT, TEXAS.
WRENCH FOR PIPE OR TUBING.
Application filed December 16, 1922. Serial No. 607,336.
f0 all whom it may concern:
Be it known that I, RICHARD DnNNin Hint, a citizen of the United States, residing at lVichita Falls, in the county of ll ichita and State of Texas, have invented a new and useful l s rench for Pipe 0r Tubing, of which the following is a specification.
The invention relates to a wrench comprising a support with a series of levers and clevises arranged thereon to grip the entire exterior circumference of pipe or tubing, and which is provided with one handle which operates the entire series of levers and clevises. The device is also provided with one steel tooth to prevent the pipe or tubing from slipping while being turned.
Another object of the invention is to provide a device of this nature which is very simple and practical and can be manufactured at a very nominal cost.
The nature and advantages of the in vention 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 of this application the various parts are referred to by numbers.
The drawing shows a view of the device with one side of the support removed.
1 is a support. 2. is ahandle pivotally attached to said support, as illustrated pt 3. 4 is a cam lever pivotally attached to the support 1, as illustratedat 5, having an offset bracket thereon pivotally attached to the clamping member 6, as illustrated at 7. The lower end of the cam lever t is formed in a forked shape to receive the round member of the handle 2 as illustrated at 8. The clamping member 9 is pivotally attached to the support 1, as illustrated at 10. The clamping member 11 is pivotally attached to the clamping member 9 as illustrated at 12. The clamping member 11 is provided with an offset portion, as illustrated at 13, which engages the aperture in the clamping member 6. member 6 has a longitudinal aperture arranged therein in association with the pin 14, which is disposed transversely through the support 1. 15 is a gripping tooth aris applied to the lever 2 for turning the The clamping ranged in the support 1. The tooth is made of a square piece of steel and held in place. with the wedge 16.
VJhen in position for use this invention provides a very efli'cient wrench for pipe or tubing and the like. One of the desirable features of this wrench is that it will not crush the pipe inasmuch as the clamping members of the wrench grip to the entire circumference of the pipe or tubing.
The dot and dash outline in the accompanying drawing shows the wrench with the jaws open. In operation it will be noted that by moving the handle 2 to the position as outlined with the dots and dashes, the cam lever 4 which is attached to the clamping member 6 moves said clamping member 6 and releases the offset portion 13 on the clamping member 1, thus permitting the jaws to be opened. lVhen the wrench is placed against a pipe or tubing the projecting portions 17 and 18 on the clamping members 9 and 11 come in contact with the pipe or tubing and automatically close the said clamping members 9 and 11 around said pipe or tubing, then by moving the lever 2 to the position as illustrated in the main drawing the hole in the clamping member 6 engages the offset portion 18 of the clamping, member 11. The power which pipe or tubing will bind the clamping members 9 and 11 to the said pipe or tubing. It will be noted that as greater pressure is applied to the handle 2 the clamping members 9 and 11 will grip the pipe or tubing more firmly.
While it is believed from the foregoing description, the nature and advantages of the device will be readily apparent, I desire to have it understood that I do'not limit myself to what is herein shown and described, and that such changes may be re sorted to, when desired, as fall within the scope of what is herein claimed.
What I claim is:
1. A wrench for pipe or tubing of the character described comprising a support, a fork shaped cam lever pivoted thereto, a hand lever pivoted to said support in association with said fork shaped cam lever, a clamping member pivoted to said fork shaped cam lever and means for providing pivotal and slidable motion thereof on said support a clamping member pivoted to said support, a clamping member pivoted to said last mentioned clamping member and means thereon to engage the free end of said first mentioned clamping member.
2. A structure as defined in claim 1 in which the first mentioned means consists of an aperture in said clamping member, and a stationary pin through said support and extending in said aperture.
