JOHN H. JENNER, OF LEAVENWORTH, INDIANA.

W R E N C H A SPECIFICATION forming part of Letters Patent No. 576,454, dated February 2, 1897.

Application filed November 6, 1896. Serial No. 611,256. (No model.)

To all whom, it may cancel-m.

Be it known that I, JOHN H. JENNER, of Leavenworth, in the county of Crawford and State of Indiana, have invented a new and Improved Wrench, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved wrench of the alligator type, and which is simple and durable in construction and readily adjustable for engaging and properly gripping pipes, rods, &c., of diiferent diameters.

The invention consists principally of a re movable jaw and a slidable jaw having its gripping-face at angles to the stock member on which the jaw is fitted to slide.

The invention also consists of certain parts and details and combinations of the same; as will be fully described hereinafter and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification,

pin D, driven transversely in the member A and through an opening in the lug B Now by removing the pin D the jaw B can be swung inward, with the offset B as the fulcrum, until the lug B is out of engagement with the memberA and then by moving the jaw B transversely the latter can be readily disengaged from the stock A. Thus whenever the jaw 13 is worn out it can be readily removed and replaced by a new one.

The jaw G is preferably made in. the shape of a casing fitted to slide on the member A and is prevented from dropping off the said member by a pin E, attached to the said member and projecting from the sides thereof to engage the sides of the jaw O. Byremoving the pin E the jaw C is slipped off the member A and replaced by a new one whenever necessary.

Now it will be seen that by the arrangement described the movable jaw O can be readily slipped or shifted along the member in which similar characters of reference indi- A according to the size of the article to be cate corresponding parts in all the figures. gripped, to make the wrench useful for grip- 2 5 Figure 1 is a side elevation of the improveping pipes, rods, and the like of different diment.
