Description

Aug. 31, 1954 s. w. PUGH ADJUSTING-SCREW LOOK FOR SLIDABLE JAW WRENCHE S Riled Dec. 20, 1951 Patented Aug. 31, 1954 ADJUSTING-SCREW LOOK FOR SLIDABLE JAW WRENCHES Stanford W. Pugh, Independence, Kans. Application December 20, 1951, Serial No. 262,545 3 Claims. 81- 165) This invention relates to adjustable wrenches and has for its principal object providing a Figure 2 is a fragmentary top plan view of.
the wrench head shown in Figure 1.
Figure 3 is a fragmentary side elevation of the head of the wrench with portions broken away Figure 4 is a side elevation of the locking, pin.
Figure 5 is a cross-sectional view of a modified worm gear showing the locking device inoperative position.
cut into the body of the locking pin midway between its ends. The shoulder 2| is not cut at a of the locking pin l8. Instead, the shoulder is cut at an angle differing from the right angle 2 position by about 10, although the angle may vary substantially.
The head of the wrench is provided with a cylindrical bore 22 in which the body of the looking pin I8 rotates. The head H is also provided with an inwardly threaded bore 23 in which the inner end of the locking pin l8 may be threaded.
In operation, the locking pin, disposed in bores 22, 23, and 24, is withdrawn along its threads 20 so that the shoulder 2| does not contact the end of worm ll. shaft of the locking pin between shoulder 2| and threads 20, moving the rack I4 and its integral jaw l3 to the desired position.
The locking pin is then rotated so that shoulder 2| is pressed tightly against worm H, as
in Figure 3. Suflicrent pressure is, applied to the and worm l7. In order to release the worm, it is merely necessary to reverse the rotation of the locking pin, removing the shoulder 2| from its bearing against the worm. In Figure 5 is shown another form of my locking device in which the locking pin 25 is provided with a taper 26. The worm 21 is provided with and worm axis and forced against each other when the pin is rotated in one direction to frictionally lock the worm against rotation.
2. An adjustable wrench according to claim 1 wherein one of said engageable surfaces forms a shoulder bearing carried by and inclined to the longitudinal axis of the pin and the other of said surfaces forms a shoulder bearing on an end of the worm.
3. Andjustable wrench according to claim 1 wherein one of said engageable surfaces comprises a tapered shoulder on said locking pin surrounding its axis and arranged-to-bear against the other surface.
