SPECIFIGATION forming part of Letters Patent No. 628,'749, lated. July 1 1, 1899;

- Application filed April 20, 1899. Serial No. '713,697. (No model.)

. To all whom it may cancel *nz Be it known that LWILLIAM A. BRADFORD, of Quincy, county of Norfolk, State of Massachusetts, have invented an Improvement in Pipe-VVrenches, of which the following description, in connection with the acconpanying drawings, is a specification, like letters on the drawings representng like parts.

This invention relatcs to a novel pipewrench adapted more especially for grasping and handlingbrass pipe or pipe which is easily scratched and narred.

My wrench contains a strong woven strap, preferablyof double thickness, the loop made at the doubled end being entered by a strong screw or pin carried by a plate having a hook to engage an eyepiece attached to the handle of the wrench. The end of the handle is shaped to support the belt at one side of the pipe embraced by the belt, the belt being sustained at its outer side near the end of the handle by a supporting stud or roller the free end of the belt being under the control of a clamp.

Figure l shows my wrench as it is being applied to a pipe. 4 Fig. 2 shows the wrench engaging a pipe. Fig. 3 is a top view of Fig. 1, and Fig. l is a detail of the connection between the strap and the handle.

The handle or handpiece A of the wrench nay be made of any usual or suitable material, preferably Wood, and its end a will be preferably cnrved to form a seat for one side of the belt f. The inner end of the handle has applied to it at opposite sides like bracket-s b, each having a depending ear, as b', in

which is mounted a roller or other stud 17 said stud occupying a position distant from the lower side of the handle substantially equal to the thickness of the belt c to be described, the brackets being firmly confined to the handle by suitable screws ?9 each bracket having preferably a projection ?9 to extend above the handle to act as edge guides for the belt embracing the pipe d. The upper side of the handle has attached to it by screws c' an eyeplate 0 said eyeplate (see Fig. 4) having an opening 0 said eyeplate covering a hole or recess 0 made in the top of the handle. The hole in the eyeplate 0 is entered by a hook or projection e, connected with a belt-holder e', having suitable ears 6 which receive a detachable screw or rod 6 which is passed through the eye forned by doubling the belt f, preferablyof woven Inaterial, on itself. The belt is stitched or otherwise united one layer with the other and is passed between the end of the handle A and the stud or roll b and thence under a clamp g, composed of a rod having a cam or eccentricand a handle g', said rod having its ends mounted in ears 9 united to said handle by suitable screws 9 p In applyin g the wrench to a pipe in position the hook may be disengaged from the eyeplate and the strap be passed about the pipe and the hook be again engaged with the eyeplate, the handle at such time being somewhat elevated, and the loop in the belt at the end of the handle and enbracing the pipe will be of a length suflicient to enable the pipe when acted upon by turning the handle to come into a position substantially parallel with and below the bearing-roll ?9 as shown in Fig. 2, where it will be seen that the pipe is wholly embraced by the belt, the latter grasping the pipe with suficient firrnness to turn said pipe.

This invention is not limited to the exac shape shown for the eyeplate and the hook, and instead I may employ any equivalent device which may be readily engaged and disengaged when desired, nor is this invention limited to the exact form of clamp illustrated.

By making the screw or bolt 6 detachable it is possible to easily remove the strap and completely detach it from the handle.

Having described my invention, what l claim as new, and desire to secure by Letters Patent, is r 1. A pi pe-Wrench consistin g of a handle, an eyepiece on the handle, a belt having a connected hook to detachably engage said eyepiece, a heavy stud to support said belt near the end of the handle, and a movable clamp for engaging said belt beyond said stud.

2. A pipe wrench consisting of a handle, a woven sti-ap folded on itself, a belt-holder ad apted to be hooked or detachably connected with the said handle, a rod carried by said holder and entering a folded bight of the strap, ears applied to the end of the handle and supporting a rod to sustain the sti-ap, and a lever pivoted on the handle and having a cam to engage the strap at desired times to clamp the same to said handle.

3. A. pipe-Wrench consisting of a handle having a pair of brackets at one end provided with depending ears and also With projections, said projections constituting edge guides,a hearing-stud supported between said ears, a belt connected at one end with said handle and supported by said bearing-stud and guided by said projections, and a clamping device for the belt.
