Specification of Letters Patent.
Patented Apr. 20, 1915.
To all whom it may concern Be it known that I, CHARLES W. EPPER- soN, a citizen of the United States of merica, and a resident of the city of Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Wrenches, of which the following is a specification.
My invention pertains to wrenches and has for its primary aim to provide a quick adjustable wrench which embodies simplified structural features thereby insuring-of durability and ease of management.
The above and other objects I attain by the construction described in the following specification, succinctly defined in the appended claims and illustrated in the accompanying drawings wherein:
igure 1 is a side elevation of my improved wrench. Fig. 2 is a top plan thereof, and Fig. 3 is a cross section taken on line 33 of Fig. 1 showing more clearly the mounting of the elements.
Referring by like characters of reference to corresponding parts throughout, 1 designates the fixed jaw having a hollow shank 2 on which slides the movable jaw 3, said shank being formed with a thickened, fiat face 2 constituting a feather or key to receive the similarly shaped key way of the sleeve support 3 of said movable jaw. The bore 4 of shank 2 extends partially the length thereof from the free end.
Shank 2 is formed with a spiral or in: clined slot 5 extending over the curved face 2" of the shank nearly the length of the key portion 2, while sleeve 3" of the movable jaw is provided with an inclined slot 6 arranged at a different pitch than slot 5 and crossing the latter to have a portion thereof registering with a portion of the slot 5.
A manipulative handle 7 is provided with a rod 8 which is operable in bore 4 of shank 2 and carries a pin 9 fixed thereto for operation in the inclined slots 5 and 6. Pin 9 is preferably threaded into rod 8 and is provided with a shoe 10 for sliding in slot 6. This serves as a means for maintaining the rod 8 and shank 2 together during the operation of the jaws.
In operation, the jaws l and 3 are placed about the object being gripped, and then the handle 7 is rotated in the proper direction to advance the pin 9 in the slots 5 and 6. This movement will close the jaws while the reverse will open the latter. It will be observed that just a slight turn of the handle is necessary to set quickly the jaws and that the full spacing or closing of the jaws will be accomplished in substantially a half turn of the handle.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States of America, 1s
1. A wrench comprising a fixed jaw having a hollow shank formed with an inclined slot, a movable jaw mounted on the shank of the fixed jaw and formed with a slot, a manipulative handle operable in the hollow shank, and a pin carried by the handle and operating in the slots of the jaws.
2. A wrench comprising a fixed jaw having a hollow shank formed with an inclined slot, a movable jaw mounted on the shank of the fixed jaw and formed with a slot, a manipulative handle operable in the hollow shank, a pin carried by the handle and operating in the slots of the jaws, and a shoe mounted on the pin and operable in the slot of the movable jaw.
3. A wrench comprising separable jaws, one slidable on the other and each pro vided with a cut-out arranged to cross the cut-out of the companion jaw, manipulative means rotatably mounted, and a pin carried by the manipulative means and operable in the cut-outs of the jaws for moving the latter toward and from one another.
Signed at Seattle, Washington, this 28th day of May, 1914.
