Inventor Attorneys WILLIAM E. URQUI-IART, OF MOSCOW, IDAHO.

PIPE-WRENCH.

Specification of Letters Patent.

Patented Apr. 29, 1913.

Application filed July 1, 1912. Serial No. 707,022.

To all whom it may concern:

Be it known that I, WILLIAM E. UR U- HART, a citizen of the United States, residing at Moscow, in the county of Latah and State of Idaho, have invented a new and useful Pipe-Wrench, of which the following is a specification.

One object of the present invent-ion is to provide a wrench so constituted that it may be used in restricted spaces.

A further object of the invention is to provide novel means for operatively connecting the fixed jaw with the handle portion of the wrench, and to provide novel means for supporting the movable jaw for sliding movement.

The invention aims further to provide novel resilient means for actuating the jawholder and the movable jaw, and to provide novel means for adjusting the tension of the resilient means.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings,Figure 1 shows the invention in side elevation; Fig. 2 is a longitudinal section; Fig. 3 is a section on the line 33 of Fig. 1; Fig. 4 is an elevation of the wrench, taken at right angles to the view point of Fig. 1; and Fig. 5 is a detail perspective of the aw-holder.

In carrying out the invention there is provided a handle 1, which preferably is straight. Extended transversely through the handle 1 are apertures, denoted by the numerals 2 and 3. Beyond the apertures 3, one side face 4 of the handle 1 is concaved, and is provided with teeth 5, constituting the fixed jaw of the wrench. In the opposite side face 6 of the handle 1 there is a recess 7 which communicates with the apertures 3.

The movable jaw is denoted by the numeral 8 and is provided adjacent its extremity with teeth 9. Projecting from the jaw 8 at right angles thereto, and preferably formed integrally therewith, is a shank 10 which may be graduated as indicated at 11, in any desired manner, and to any extent, to indicate different diameters of pipe. The

shank 10 of the movable jaw is threaded as indicated at 12.

There is provided a jaw-holder, denoted generally by the numeral 14, and shown in clearest outline in Fig. 5. The jaw-holder 14 is preferably in the form of a block, and is equipped with oppositely disposed openings 15, there being other openings 16 through the jaw-holder, at right angles to the openings 15. Extended laterally from the base of one of the openings 15 is a projection 17 having a transverse opening 18. Projecting from one end of the jaw-holder 14 is a hook 19.

The shank 10 of the movable jaw S is inserted through the recess 3 of the handle 1 and through the openings 15 in the jawholder 14, the jaw S lying opposite to the fixed jaw 5, and the jaw-holder 14 bearing against the side face 6 of the handle 1, the project-ion 17 extending into the recess 7, and a pivot element 19 being inserted through the handle 1 and through the opening 18 in the projection 17, to afford a pivotal mounting for the j aw-holder 14. A nut 20 is threaded upon the portion 12 of the shank 10, the nut 20 being mounted for rotation in the openings 16, and projecting laterally beyond the j aw-holder 14.

The shank 21 of the hook 19 ordinarily extends through one wall of the j aw-holder 14, and is provided terminally with a button 22. When the nut 20 is in place, the nut engages the button 22 to hold the hook 19 in place. A retract-ile spring 23 is mounted in the recess 2 of the handle 1, the spring 23 terminating at one end in an eye 24 which is engaged with the hook 19. Secured in the other end of the spring 23 is a threaded stud 25, carrying a nut 26 which bears against the side face 4 of the handle 1.

The jaws 5 and 8 may be separated by rotating the nut 20. When the jaws 5 and 8 have been set to the approximate diameter of the pipe, the pipe may be inserted between the jaws, the jaw-holder 14 swinging upon its pivotal mounting 19, tht spring 23,

being thereby put under tension, the function of the spring 23 being to hold the jaws 5 and 8 engaged with the pipe. The tension of the spring 23 may be adjusted by rotating the nut 26 which is engaged with the stud 25 and with the side face 4 of the handle 1 of the wrench. It is to be noted that the projection 17 exercises a double function, and that, at once, it constitutes a means for pivotally connecting. the j aw-holder 14 with the handle 1, and constitutes also, a support upon which the shank 10 of the movable jaw 8 is mounted to slide.

Generally considered, the wrench herein disclosed is of compact form, and the relation between the jaws 5 and 8 is such that the wrench may be employed with advantage for pipe fitting between joists, and in other localities, where a pipe wrench having rectangularly disposed jaws could not be used.

Having thus described the invention, what is claimed is 1. In a wrench, a handle having a jaw along one of its side faces; a jaw-holder lying along the opposite side face of the handle and pivoted adjacent one end to the handle; a movable jaw opposite to the fixed jaw and having a shank extended through the handle and through the jaw holder; a nut threaded upon the shank and mounted for rotation in the jaw holder; a retractile spring having an exposed end detachably connected with the other end of the jaw-holder the spring being extended through the handle beyond the jaw holder; and tension adjusting means connected with the other end of the spring and engaged with the first specified side face of the handle.

2. In a wrench, a handle having a jaw along one of its side faces; a jaw-holder lying along the opposite side face of the handle and pivoted adjacent one end to the handle; a movable jaw opposite to the fixed jaw and having a shank extended through the handle and through the jaw-holder; a nut threaded upon the shank and mounted for rotation in the jaw-holder; a retract-ile spring connected with the other end of the jaw holder and extended through the handle; a threaded stud carried by'the free end of the spring; and a nut upon the stud, bearing against the j aw-carrying face of the handle.

3. In a wrench, a handle having a along one of its side faces and provided with a recess in its opposite side face; a jawholder lying along the recessed side face of the handle and having a projection entering the recess; a pivot element connected with the projection and with the handle; a movable jaw disposed opposite to the fixed jaw and having a shank extended through the handle and through the jawholder, and slidably supported upon the projection; a nut threaded upon the shank and mounted for rotation in the jawholder; a hook upon one end of the jawholder, remote from the projection; a retractile spring removably engagtd at one end with the hook and extended through the handle; a threaded stud connected with the other end of the spring; and a nut upon the stud, bearing against the jaw-carrying face of the handle.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.
