Application filed September 29, 1902. Serial No. 125 ,303. (No model.)
In the accompanying drawings, Figure 1 is a face elevation, partly in sect-ion, showing the movable jaw clamped in position. Fig. 2 is a face elevation, partly in section, showing the movable jaw free to'be moved. Fig. 3 is an under face view. Fig. at is an isometrical representation of the pivoted lever. Fig. 5
.is an isometrical representation of the slidlng aw. Fig. 6 is an isometrical representation of the movable jaw.
The main portion of the wrench comprises the handle 1, head 2, and stationary jaw 3. The head has a slot 4. and a guideway 5. The movable jaw shown at Fig. 6 has a shank portion 6 and offset portion 7. The shank portion has a lengthwise groove 8,.fitted to slide in connection with the projection 9 of the head. One of the faces of the movable jaw is formed with a toothed rack 10. The sliding jaw has a toothed rack 11 and a projection 12. A pin 13 is supported by the projection 12, and a plate-spring let is held in connection with the projection by the pin. The lever 15 (shown at Fig. 4.) has a hole 16, receiving its pivot-pin 17. The sliding jaw is located in'the slot 4 in the head of'the wrench,
and the lever 15 is also located in the slot and held in a pivoted manner by the pin 17. The movable jaw is placed in the guideway 5 of the head.
When the parts are in the position shown at Fig. 1, the movable jaw is held in connection with the head of the wrench by the teeth of the sliding jaw engaging the teeth of the movable jaw and the lever holding the sliding jaw in position. The spring bears against the short end of the lever.
By raising the lever the short end will engage the pin 13 and move the sliding jaw from its engagement with the movable jaw, when the parts will appear as shownat Fig. 2 and the movable jaw is free to be adjusted to fit the nut which the wrench is to turn, when the lever is depressed, which will engage the slidsion, a pin supported byth'e extension, and
a pivotal lever one end of which engages the movable jaw, also the pin.
