Attorneys WILLIAM H. EVERETT, OF MOUNT PLEASANT, PENNSYLVANIA.

WRENCH.

Specification of Letters Patent.

Patented J an. 11, 1916.

Application filed January 22, 1914. Serial No. 813,727.

1 b all whom it may concern Be it known that I, VILLIAM H. EVERETT, a citizen of the United States, residing at Mount Pleasant, in the county of Viestmoreland and State of Pennsylvania, have invented a new and useful Wrench, of which the following is a specification.

he present invention appertains to wrenches, and aims to provide a novel and improved device of that character.

lt is the object of the present invention to provide a wrench embodying a novel assemblage of parts wherein the stationary and movable jaws are articulate with one another, whereby the movement of the handle is employed for opening and closing the jaws automatically.

Another object of the present invention is to provid a wrench of the nature indi cated, having improved structural features, to render the construction compact, durable and efiioient, as well as simple and inexpensive. l

'lVith 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 the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention has been illustrated in its preferred embodiment in the accompanying drawing, wherein Figure 1 is a side elevation of the improved wrench, portions being broken away. Fig. 2 is a longitudinal section taken on the line 22 of Fig. 1. Fig. 3 is an end view of the wrench, looking toward the jaws. Fig. 4 is a perspective view, on a reduced scale, of the slide and movable jaw carried thereby.

The body of the wrench comprises a pair of spaced cheek or side plates 1 having an outstanding integral fixed or stationary jaw 2 at one end of their outer edges adjoining certain side edges, as clearly seen in Fig. 1.

A fiat slide 3 is disposed snugly between the cheek or side plates 1 adjoining and flush with their outer edges and movable adjacent the fixed jaw 2, the outer edge of the slide 3 being equipped with an outstanding integral movable jaw l slidable upon the outer edges of the cheek or side plates 1 and arranged at that end of the slide 3, opposite the fixed or stationary jaw 2. slide 3 is curved, and is spaced from the inner edges of the check or side plates 1.

The cheek or side plates 1 are provided with inner transverse grooves or channels 5 adjoining their outer edges which receive the tongues or ribs 6 formed upon the faces or sides of the slide 3 and extending longitudinally of the slide, or transversely of the wrench as a whole. The interfitting tongues 6 and grooves 5 guide the slide for sliding or reciprocatory movements, to thereby permit the movable jaw 4 to move to and from the fixed or stationary jaw 2.

A U-shaped reinforcing clip 7 straddles those side edges of the cheek or side plates 1 r at those ends of the outer edges of the cheek plates opposite those adjoining the stationary jaw 2, and is disposed adjoining the outer edges of the cheek plates, the terminal portions or arms of the clip 7 being secured upon the cheek plates 1 by means of removable screws or other securing members 8 engaged through the arms of the clip and taking into the cheek plates, whereby the clip 7 will serve to strengthen and brace those side edges of the cheek plates 1 opposite the fixed jaw 2, which connects the side plates at the corresponding side edges. The clip 7 also assists in limiting the opening movement of the jaw 4 away from the fixed jaw 2, the end of the slide 3 being arranged to be received by the clip 7 to arrest the movement of the slide at a predetermined position. When the clip 7 is removed, it will permit of the withdrawal of the slide 3 from between the cheek plates, when desired.

A handle or lever 9, which may be of any suitable length, is pivoted adjoining its outer end between the inner edge portions of the cheek plates 1 at those side edges adjoining the stationary jaw 2, by means of a pivot 10. Thus, the-handle or lever is fulcrumed or pivoted between the cheek plates at that inner corner adjoining the stationary jaw, whereby the handle when in longitudinal position, as seen in Fig. 1, will practically aline with the stationary or fixed jaw 2. The pivot 10 preferably embodies two sections or members detachablv connected by means of screw threads, or the like, as clearly illustrated in Fig. 2, a spacing collar or ring 11 being mounted upon the pivot 10 to prop The inner edge or the erly hold the handle or lever 9 adjoining one check plate 1. The handle or lever is thus fulcrumed to the stationary jaw, and is articulate with the slide 3 carrying the movable jaw, in the manner which will be presently described. The outer end of the handle 9 is provided with a tongue or lobe 12 adjoining one check plate 1, and the slide 3 is provided in the corresponding side with a recess or depression 13 receiving the tongue or lobe 12, the recess 13 being disposed between the respective tongue or rib 6 and the inner edge of the slide, and having a curved wall, as seen in Fig. 1. The slide 3 is provided, midway between its ends, with an integral lug or pin 14 within the'recess or depression 13, while the free or outer end of the lobe 12 is provided with an open slot 15 engaging the lug or pin 14:, whereby when the handle or lever is oscillated relative to the cheek plates 1, the slide 3 will be given a rectilinear or sliding movement.

For facilitating the gripping of small nuts and other objects by the jaws, the same are preferably provided in their faces with transverse V-shaped grooves 16, which are intended to receive the opposite corners of the nuts, when the jaws are closed.

In use, when the handle or lever 9 is swung in one direction, to the right, as seen in Fig. 1, the slide 3 will be slid toward the clip 7 carrying with it the movable jaw 4, to thus open the jaws for permitting them to be engaged over a nut, pipe or other object. Then,

when the handle or lever is swung in the other or opposite direction, the slide 3 will be moved so as to force the aw at toward the stationary jaw 2, to thereby grip the nut, pipe or other object, and at the same time, a torsional or twisting strain may be imparted to the nut, or other object, for the purposes desired. It will thus be evident, that the jaws are automatically opened and closed by the movement of the handle, thereby avoiding the necessity of adjusting the jaws prior to their application to an object.

Particular attention is directed to the fact that the operative connection between the component parts renders the structure of the wrench thoroughly practical and eflicient, it also being noted that the pivot of the handle or lever is in line with the face of the fixed jaw, whereby when the movable jaw t is midway between the ends of its movements, the handle or lever will approximately aline with the stationary jaw, or will lie in the plane of the face of the said jaw, which is desirable. The pivot is not offset from the fixed jaw, as in certain other wrenches of this character, and as a result of the arrangement above described, the handle or lever can be more conveniently and eiliciently employed for the purposes intended. hen the slide is moved to its extreme position in one direction, or toward the clip 7 one end portion of the wall of the recess or depression 13 moves toward or en gages one side edge of the tongue or lobe 12 to assist in limiting the movement of the slide and movable aw, and when the slide is moved in the other direction to close the jaws, the same action will take place between the other side edge of the tongue or lobe 12 and the other end portion of the wall of the recess or depression 13.

The present device may be employed as a nut or pipe wrench or as a. pipe cutter, by properly forming the aws 2 and i, as will be obvious to those versed in the art.

Having thus described the invention, what is claimed as new is A wrench embodying a pair of cheek plates, having an outstanding jaw, a'slide mounted between the cheek plates and having an outstanding jaw, the cheek plates and slide having interfitting tongues and grooves, one side of the slide having a recess adjacent one cheek plate and a lug or pin within said recess, a pivot element engaged through the cheek plates, a handle pivotally mounted upon said pivot element and having a lobe projecting into said recess and provided with an open slot receiving said lug or pin, and a spacing collar upon said pivot element between the handle and other cheek plate, the pivot element being composed of two sections thread ed together between the handle and spacing collar.

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

WILLIAM H. EVERETT.
