WRENCH.

Specification of Letters Patent.

Patented March 3, 1908.

Application filed June 15, 1907. Serial No. 879,173"

type commonly styled monkey wrenches.

The invention has for its object to provide a quick acting wrench wherein the use of screw threads and nuts is entirely eliminated for adjusting the movable jaw of the wrench.

Another object of this invention is to pro vide a simp e, inexpensive and durable wrench, that can be easily and quickly adjusted, the wrench being articularly designed for rotating nuts and similar objects havin flat surfaces.

Wit the above and other objects in view which will more readily appear as the invention is better understood, the same consists in the novel construction, combination and arrangement of parts to be presently described and then specifically pointed out in the appended claims.

Referring to the drawings formin a part of this specification, Figure 1 is an e evation of a wrench illustrating the movable jaw thereof in section, Fig. 2 is a cross sectional view of a portion of the movable jaw taken on the line xa: of Fig. 1, Fig. 3 is a horizonjzal sectionafl ilir iew of la wrench taken on the ine 'y'y o i 1, ig. 4 is a perspective view of the locking 'member of the wrench.

To put my invention into practice I construct my wrench of a shank 1 having a fixed head or jaw 2. The shank upon its under edge is provided with teeth 3, and while the shank can serve functionally as a handle, I desire the privilege of placing the handle upon the shank if necessary.

Slidably mounted upon the shank 1 is a movable jaw 4, having straps 5 embracing "the shank. The jaw 4 is provided near its upper end with a longitudinal] dis osed o ening 5 having the si e walls t ereo provided with oppositely dis osed grooves to he opening 5 extends from one en of the jaw and is contracted at the other end, as at 7. Communicating with the opening 5 is a vertically disposed opening 8 for a headed pin 9 secured in a locking member 10 slidably mounted the opening 5. The locking member is provided upon its sides with ribs 11 adapted to fit in the guide-ways 6 of the jaw 4. The forward end of the locking member terminates in a tooth 12 adapted to extend from the contracted end 7 of the opening 5, while the rear end of the locking member 10 is bifurcated as at 14 and formed with a shank or pin 15. Surrounding the pin or shank 15 and within the opening 5 is a coil spring 16 confined within the opening under tension by a late 17 suitably secured to the outer end 0 the jaw 4. The tension of the sprin 16 is adapted to maintain the tooth 12 o the locking member in enga ement withthe teeth 3 of the shank 1, an when in such position, the tooth 12 is ada ted' to fit snugly in the contracted end of t e opening 5. To release the locking member from engagement with the shank 1, the headed pin 9 is manipulated, said pin being moved towards the outer end of the jaw 4, withdrawing the locking member from engagement with the shank 1 and permitting of the jaw 4 being adjusted. The aw 4 can be quickly closed, as the beveled teeth 3 of the shank permit of the locking member residing over the shank while the jaw is being closed, but prevents such jaw from being opened, unless the locking memher is manually moved out of engagement with the shank.

The wrench in its entiret is constructed of strong and durable meta and the manner in which the operating parts of the wrench are housed prevents the wrench from being injured by ordinary use.

Such changes in the tion as are permissible by the appended claims may be resorted to without departing from the spirit and scope of the invention.

What I claim, and desire to secure by Letters Patent, is

A wrench comprisin a toothed shank having a fixed jaw, .the aw slidably mounted uponsaid shank, the upper portion of said slotted jaw provided wit an opening having the inner end thereof contracted, the side walls of said opening formed with grooves to constitute guide ways, a locking member arranged in said opening and provided with lon itudinally extending ribs seated in said guiiie ways, said member having its forward end formed with a tooth adapted to extend through the contracted end of the opening details of construcand en age with the teeth of the shank and the shifting locking member and its other end 10.

said 100 g member having its other end biprojecting from the jaw.
