PIPE-WRENCH.
SPECIFICATION forming part of Letters Patent N 0. 516,661, dated March 20, 1894. Application filed November 23. 1892. Serial No. 452,963. (No model.)
To all whom it may concern.-
Be it known that I, ORAMEL O. STANLEY, a citizen of the United States, and a resident of the city, county, and State of New York, have invented certain new and useful Improvements in Pipe-Wrenches, of which the following is a specification.
My invention relates to pipe wrenches having a fixed and a movable jaw, and consists of 1o combinations of devices hereinafter described and is more particularly pointed out in the claims concluding this specification.
The objects of my present invention are to avoid crushing pipes, to obtain a firm hold 1:; thereon and yet one that can be instantly and easily released, and to remove all strain from the pin or rivet of the pivoted parts, and other objects as will hereinafter appear.
The preferred form of myinvent-ion is shown in the accompanying drawing, forming part of this specification, in which The letter A indicates the main bar of a wrench,said bar having the head jaw2 integral therewith, and having a polygonal (squared 2' 5 in this case) part 3, a screw-threaded end 4,
and ratchet teeth 5 on one side intermediate the part 3 and jaw 2. It also has two shoulders 6 near the jaw 2, all for purposes hereinafter stated. A hollow handle 7, of metal, has 30 a square opening 8 to fit squared part 3 to prevent it from turning independently of the main barA. Ascrewnut 9 engagesthe screw thread 4 and holds the handle 7 in place.
A sleeve D of metal fits and slides upon the 3 5 main bar A. The said sleeve D has a central partition 10 lying on the main bar A. The sides of the sleeve D extend some distance above the partition 10 and are connected by the walls 11 and 12. The wall 11 runs at right angles to the bar A, and with wall 12 and partition 10 and the sides of the sleeve D, form a socket 13. The socket 13 hasa rounded (or cylindrical), bottom 14. Pivoted loosely on pin 15 (it is usually a rivet) passing through 5 socket 13 at the centerof the rounded bottom is the back jaw B, having a rounded end 16 to fit rounded bottom 14. The jaw B has a socket 17 in the bottom which comes opposite a perforation 18 in the central partition 10.
56 A spiral spring 19 in the socket and perfora-' tion 18 and pressing against the main bar A, holds the jaw B away from the bar A. The central partition 10 forms a stop against which the jaw B comes, so that there is no danger of crushing the pipe, for the teeth of jaw B can only bite so deep into the pipe without crushing it. That is, the movement of jawB is such that the pressure on the pipe is sufficient to embed the teeth of jawB in the pipe more or less, but is not sufficient to crush the pipe. At the other end of the sleeve D, I pivot. the holding trigger 0 having ratchet teeth 20 to engage the ratchet teeth 5 of the main bar A. For some purposes of my invention, other means of holding the sleeve D against motion away from the head jaw 2 may be used, but I prefer that shown. The trigger G is formed with a bearing 21 which abuts against the end of partition 10. A spiral or other spring 22 under the thumb-piece 23 of 7c trigger O depresses the ratchet end thereof against the bar A. The trigger O and jawB have play on their pins so that there shall be no strain thereon when the wrench is in use.
In assembling the parts, the jaw B is put in place, also the spring 19 is slipped into place through perforation l8 and the sleeve D is then slipped over the bar A, the handle 7 put on, &c.
In use, the operation of the parts is as fol-, 8o lowsz-The pipe is taken between the jaws, the sleeve D slid along toward jaw 2 until the pipe is gripped, the trigger O sliding over and engaging the teeth 5. On moving the end of the handle as indicated by arrow f, the jaws 2, B, grip the pipe, jaw Br-moving toward bar A, until stopped by partition 10. There is no pressure on pin 15, since jaw B has play there- .on, and the end 16 thereof bears against the bottom 14 of the socket 13. The pressure thus o taken by the sleeve D is transmitted through the trigger O to the teeth 5 of bar A, the trigger hearing at 21 against the end of the sleeve D or its partition 10. The friction caused by spring 19 on bar A, and by spring 22 through trigger O on the teeth 5 serves to hold the sleeve D against accidental displacement.
So far as the functions of the partition 10 as a stop for the jaw B go, it may be replaced by a pinor other equivalent. Ioo
Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-
1. In a pipe-wrench, the combination of a main bar, a slidable sleeve thereon having a central perforated partition lying on said bar, aback jaw pivoted to said sleeve and having a socket, and a spring in said socket and perforation and bearing against said bar, substantially as and for the purposes set forth.
2. In a pipe-wrench, the combination of a toothed main bar, a slidable sleeve thereon having a perforated central partition lying on said bar, a back jaw pivoted to said sleeve and having a socket, a spring in said socket and perforation and bearing on said bar, a toothed trigger pivoted to said sleeve, and a spring pressing said trigger against said bar, substantially as and for the purposes described.
3. The combination of bar A having the fixed jaw; a sleeve comprising a socket 13 having the rounded bottom 14:, partition 10 having a perforation 18; the pin 15; the pivoted jaw B provided with round end 16, and a perforation or hole loosely receiving pin 15; and a spring in perforation 18 bearin g against bar A and jaw 13, substantially as described.
4. The combination of bar A having .the
fixedjaw; a sleeve thereon comprising a socket
