WRENCH.

Specification of Letters Patent.

Patented July 4, 1916.

Application filed-December 15, 1915. Serial No. 68,941.

T all whom it may concern:

Be it known that I, MERRILL C. RAIKES, a citizen of the United States, residing at Philippi, in the county of Barbour, State of Vest Virginia, have invented a new and useful rench; and I do hereby declare the followin to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved wrench, and an object of the invention is to provide a device of this nature, in which eificient, practical and improved features of construction are involved.

Another object of the invention is to provide a quick adjustable wrench jaw, which is slid-able upon the shank of the cooperating jaw, and is provided with a pivoted handle having teeth to coiiperate with teeth of the other handle, to hold the sliding jaw in adjusted position.

Another object of the invention is to provide spring means to hold the pivoted handle in close engagement with the other handle, as the wrench is in use, thereby preventing the pivoted handle from separating.

In practical fields the details of construction may necessitate alterations, falling within the scope of what is claimed.

The invention comprises further features and combination of parts, as hereinafter set forth, shown in the drawings and claimed.

In the drawings: Figure 1 is a view in perspective of the improved wrench constructed in accordance with the invention, showing the jaws separated, and the two handles in contact. Fig. 2 is a view in perspective of the wrench showing the pivoted handle swung open. Fig. 3 is a view partly in section and partly in elevation, showing the jaws separated and illustrating the handles closed. Fig. 4. is a sectional view on line 4.- 1 of Fig. 3. Fig. 5 is a detail view of portions of the two handles showing the cooperating teeth 3 and 25.

Referring more especially to the drawings, 1 designates the stationary jaw having a shank 2, which constitutes a handle, and upon one face of this shank a series of teeth 3 is-provided. The opposite side faces of the shank 2 are provided with longitudinally arranged elongated ribs 4. A movable jaw 5 is provided having a rectangular opening 6, through which the shank 2 of the jaw 1 extends. Opposite walls of this opening 6 are provided with grooves 7, which receive the ribs 4. The jaw 5 is provided with a socket 8, in which the lug 9 is pivoted upon the pin 10. This socket 8, as shown in Fig. 3 is angular, so that the walls 11 and 12 will limit the lug 9 of the handle 12 in either direction. Where the socket 8 is formed, the jaw is curved as shown at 13 upon an arc, using the pin or bolt as a center. The lug 9 projects from the curved surface 14. of the pivoted end of the handle 12*, which curved surface 14: is concentric with the curvature 13, so that the two surfaces will slidably engage, as the handle 12 is swung open as shown in Fig. 2. The pivotal end of the handle 12 has a lip 15 overlying the curved part 13 of the jaw 5. The outer surface of this lip is curved as shown at 16, and is provided with a notch 17 Pivoted between the lugs 18 of the jaw 5 upon the pivot 19 is a dog 20, the nose '21 of which engages the notch 17 so that by the action of the spring 22 (which is interposed between the tail end 23 of the dog and the rear portion of the jaw 5) the handle 12- is held against the shank or handle 2, thereby preventing the handle 12 from swinging open while the wrench is being used. The handle 12 is provided with teeth 25, adapted to cooperate with the teeth 3 of the shank or handle 2, so as to hold the movable jaw in different adjusted positions. When the handle 12' is opened. it is necessary to depress the tail end 22 of the dog, so as to permit the nose of the dog to engage the curved surface 16 of said lip, and between the two flanges 26.

The invention having been set forth, what is claimed as new and useful is:

1. In combination, a stationary jaw having a handle or shank, a movable jaw slidable upon the shank, said shank having a series of teeth upon its inner face, the rear portion of the movable jaw having a socket and provided with a semicircular curved part where the socket is formed, a second handle having a curved end surface and a lip coiiperating with the circular curved portion of the movable jaw, and provided with a lug pivoted in said socket, said sec ond handle having teeth to cooperate with the teeth of the shank or first handle.

2. In combination, a stationary jaw having a handle or shank, a movable jaw slidable upon the shank, said shank having a series of teeth upon its inner face, the rear portion of the movable j aw having a socket and provided with a semi-circidm curved part where the socket is formed, a second handle having a curved end surface and a lip cooperating with the circular curved portion of the movable jaw, and provided with a lug pivoted in said socket, said second handle having teeth to cooperate with the teeth of the shank or first handle, said lip upon its outer surface having a notch, and a spring tensioned dog having its nose engaging said notch, to hold the piYoted handle against the shank of the stationary aw, said pivoted handle ad aQent the lip being provided with side flanges, between 15 which the nose end of the dog engages, when disengaged from the notch.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
