SPEGIFIGATION'fOrming part of Letters Patent No. 738,565, dated September 8, 1908. Application filed February 24, 1903. Serial No. 144:;689- (N 11106181) To all whom it may concern:
. of Fig. ,1.
Our invention relates to the class of wrenches havinga movable screw-actuated jaw, and is designed toiprovide a simple and effective wrench of this character which may be cheaply made and may be readily adjusted.
In the drawings, 2 represents the fixed jaw secured at the end of the stem 3, this stem being rectangular in cross-section in its upper portions, with the lower part slotted or recessed to form the depending legs 4 4.
The movable jaw 5 is provided with straps 6 and 7, which encircle and fit neatly about the stem 3, and from the lower strap 7 extend the side straps 8 S, which extend downwardly on the flat sides of the stem 3 and are connected at their lower ends by the integral cross-bar 9, which extends through the slot between the legs 4 and is provided with a screw-threadedhole extending through it. A longitudinalscrew 10 extends through the hole in the cross-bar 9 and engages its screwthreads, the upper end of the screw being rounded and seated in a curved recess at the 3 upper end of the slot in the stem 3. The lower end of the screw has a shoulder which bears upon a cross'bar 1 1, riveted or otherwise socured to the lower ends of the legs 4. The reduced cylindrical portion 12 of the screw extends through a plain hole in the cross-bar 11 and is pinned or otherwise secured to the turning block or handle 13. We have shown screwed into place, and the lower cross-bar 11 is then riveted or secured to the lower ends of the legs 4. The handle 13 is then secured to the lower end of the screw.
In operating the wrench the turning of the part 13 will move the jaw 5 toward or from the fixed jaw, the straps 8 sliding along the sides of the shank or stem 3.
The advantages of our invention result from the simplicity and cheapness of the device, which is strong and efficient and not, liable to get out of order.
Any suitable handle may be secured around the legs 4 which will allow proper movement of the parts, and other variations may 'be made in the form and arrangement of the parts without departing from our invention.
We claitn- 1. A wrench having a jaw secured to a shank, said shank having depending logs, the other jaw being secured to a loop encircling the shank, and having depending side straps whose plane is at right angles to the plane of the shank-legs, said straps having a connect ing cross-bar with a screw-threaded hole and extending through the slot between the shanklegs, and an actuating screw extending through the threaded hole in the cross-bar and having its upper end abutting against the shank at the upper end of the legs; substantially as described.
2. A wrench having one jaw secured to a shank provided with depending legs, the other jaw having depending side straps connected at their lower ends by a crossbar extending through the space between the legs of the shank, an actuating-screw extending through a screw-threaded hole in the cross-bar and engaging the shank at its upper end, a lower cross-bar connecting the shank-legsand form ing a rear abutment for the screw, and mechanism for turning the screw; substantially as described.
3. Awrench having a fixed jaw secured to a shank, having depending legs, a movable jaw connected to an encircling strap provided with depending side straps extending downwardly along the sides of the shank and having a connecting cross-bar at their lower ends extending between the shank-legs, a longitudinal screw engaging a screw-threaded hole vIIOC) in the cross-bar and having its upper end en- In testimony whereof We have hereunto set gaging the shank at the upper end of the slot our hands. 7 between the le s a lower cross-bar secured to the lower en s of the shank-legs and forxning an abutment for the screw, and a turning-handle secured to a screw-stem projeet- Witnesses:
