WRENCH. Y

Application led May 20, 1926. Serial No. 110,456,

Figure 1 is a side elevation of my im-` proved wrench.

Figure 2 is a fragmentary vertical section taken substantially upon the line 2-2 of Figure 1. I

Figure 3 is a perspective view of. one of the locking members for maintaining the sliding jaw in adjusted position, and

Figure 4 is a perspective view of the releasing means for said member.

Now having particular reference to the drawing, my novel wrench constitutes the provision of a conventionally designed stationary jaw 5 formed upon or attached to one end of a fiat like handle 6 of predetermined length, one side of which is formed with transversely extendingspaced beveled teeth 7.

Slidably arranged upon the handle 6 is a sleeve 8 the inner end of which is formed with a jaw 9 complementary to the stationary jaw 5. Adjacent opposite ends of the sleeve 8 one side of the same is formed with sockets 10-10 that communicate at their inner ends with the bore of the sleeve, the outer ends thereof being provided with annular flanges as at `11--11. .Slidably arranged within the sockets are pinsv 12-12 the inner ends of which are formed with beveled heads 13, the edges of which are adapted for engagement between the teeth Tof the handle 6, for locking the sleeve against sliding movement upon said handle.

Surrounding these pins between the 'head 13 and the iianges11 ofthe sockets are eXpansible coil springs 14 that serve to normally maintain the heads in engagement beneath said teeth.

The outerends of the pins project through the flangesV 11V of the sockets and have attached thereto metallic lstrips 15 that eX- tendtoward each other as clearly disclosed in Figures 1 and 2. The free ends of these strips are curved slightly outwardly and are formed with thumb or finger engaging La enlargements 16. By reason of the free ends of these plates being bent outwardly, the same may be rocked upon the surface of the sleeve 8 for causing the pins to slide outwardly against the action of the yspring 14 which will release the same from the teeth 7 of the handle 6 so as to permit the sliding of the sleeve upon said handle.

It will thus be seen that I have provided a highly novel, simple and eflicient form of wrench that is well adapted for all the purposes heretofore designated and even l though I have herein shown and described the same as consisting of certain detail lstructural elements it is nevertheless to be understood that departures may be had therefrom without effecting the spirit and scope of the appended claim.

Having thus described the invention, what I claim as new and desire tosecure by Letters Patents is j Ina wrench of the class described, a handle, a stationary jaw formed on one end thereof, there being transversely extending spaced teeth formed on one side of the handle, a jaw carrying' sleeve slidably mounted on the handle, said sleeve having transversely arranged sockets formed in one side thereof adjacentvits upper and lower ends, said sockets' communicating at their inner ends with the bore of the sleeve, an annular flange in the outer end portion of 'each socket, a pin arranged in each socket,

tid

the pins out of engagement with the teeth, said means comprising a pair of metallic strips secured at their outer ends to ythe respective pins, the outer end portions of the strips engaging the respective annular' FRANK VDOMINELLI.
