. RIPE-WRENCH,

' To all whom it may concern:

Beit knownthat I, HAROLDKING, a'citi-v zen of the United States, residing at Bascom, in the county of Seneca and State of Ohio, have invented a new and useful Pipe- Wrench, of which the following is a specification.

The device forming the subject matter of this application is a pipe wrench, and the present invention aims to provide novel means for operatively assembling a pipe grip with the movable j aw of the wrench.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

With the above andother objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the detailsof construction hereinafter described Fig. 4 is a section-taken approximately on the line H of Fig. 2; Fig. 5 is an end elevation of the grip which is carried by the movable The wrench forming the subject matter of this application includes a body 1 carrying a handle 2, the body 1 being provided with a fined jaw 3 equipped with teeth 4. Slidable along the body.1 is a movable aw 5 controlled by a nut 6 threaded onto the body 1 and coacting with the movable jaw in a common and well known manner.

The laterally projecting portion of the upper edge of the movable jaw 5 is inclined as shown at 7 and is provided at its sides with dove-tailed ribs 8. Disposed in the movable j aw 5 between the ribs 8 is a groove 9. The side portions of the movable jaw 5 are connected by a cross bar 10 which defines the rear end of the groove 9.

Threaded into or otherwise secured to the movable jaw 5 within the contour of the Specification of Letters Patent.

I Application filed December 9, 1915. Serial No. 65,964.

groove 9 is a stud 11 spaced as shown at 12 from the side walls of the groove and from the cross bar 10.

A wedge-shaped grip 141 slide on the movable jaw 5 and is provided w ith teeth 15 adapted to coiiperate with the teeth 1 on the fixed jaw 3. At its sides, the grip 1 1 issupplied with dovetailed ribs 16 coacting with the dove-tailed ribs8 on the movable jaw 5,

the construction being such that the grip 14.

may slide to and from the body portion 1 of the wrench. Extended from the grip 14 near to the forward end thereof and entering the groove 9 in the movable jaw 5 is an eye 17. A compression spring 18 abuts at its rear end against the stud 11 and abuts at its forward end against the eye 17. A spring support in the form of a screw 19 passes through the eye 1? and is threaded at its rear end into the stud 11, the screw 19 passing through thespring 18. The screw 19 terminates in a head 20 which, engaging the forward face of the eye 16, limits th outward movement of the grip 1 1.

The spring 18 forces the movable grip 14 outwardly and assists the movable grip in obtaining and holding a grip on the pipe or other circular object which is to be rotated.

This spring, further, is housed in an out of the way position in the groove 9, and cannot be injured.

Especial attenti an is directed to the fact that the movable jaw 5 includes the lug or ,stud 11. Owing t) the fact that the stud 11 is provided, it is .innecessary to bore a hole into any part of he movable jaw 'proper, to receive the inner end of the screw 19. The movable jaw 5, consequently, is not weakened, the stud being spaced as shown at 12 from the body portion of the movable jaw. It is to be obser ved that the upper end ofthe stud 11 is be eled to correspond with the slope indicatel at 7, the stud thus constituting an additional means for supporting and guiding the' grip 14.

Having thus described the invention,what is claimed is:'

1. A wrench embodying a material-holding jaw having a groove; a removable stud 'threaded into the jaw within the contour of the groove and spaced peripherally from the wall of the groove; a spring holder projecting from the stud; a grip slidable on the jaw and on the end of the stud and. provided with an eye receiving the spring holder slidablyt and a; compression spring interposed between the eye and the stud.

2. A wrench embodying a material hold}. ing jaw having a groove; a removable stud mounted in the jaw within thecontour of the groove and spaced peripherally from the wall of the groove; a spring holder projecting from the stud; a grip slidahle in the jaw and provided'with an eye meaning the spring holder slidably; and aeompression spring interposed between the eye and the stud. i

In testimony that I claim the foregoing as my own, I have hereto aflixed my slgna- I
