WRENCH.
SPECIFICATION forming' part of Letters Patent No. 717,400, dated December 30, 1902.
j Application filed October 14, 1902. Serial No. 127,263. (No model.)
This invention relates to Wrenches; and thev object thereofisto provide a wrench having a novel construction of jaw, whereby different forms of nuts or tabs can be engaged to be turned upon the bolt.
The peculiar manner of accomplishing thev desired result Vwill be described .hereinafter and illustrated in the accompanying drawings, in which- Y Figure lisa side elevation of a wrench constructed in accordance with my invention. Fig. 2 is a slightly-modified form, and Fig.` 3 is a still further modified form. Fig. l is a fragmentary perspective view of a portionof the wrench, illustrating the slot in the lower jaw for thereception ofthe angular plate.
The reference-numeral l designatesthe shank of a wrench, on one end of which is a handle 2. On the other end of the shank is a laterally-extending rigid jaw 3. to the rigid jaw andthe shank is an inclined rib 4, which in the preferred form is in the nature of a platein the form of a right-angle.
triangle fitting into the right angle formed by the juncture of the rigid jaw with the shank. Slidably s ecured on the shank is a movable jaw 5, which can be operated by means of a screw 6, whereby the moving jaw can be adjusted toward or away from the rigid jaw. It will be noticed that the sliding jaw projects laterally beyond the extremity of the rigid jaw, the purpose of which will be explained-presently. In order that the sliding jaw may .be adjusted to abut against theV rigid jaw, I provide a recess 7 in the sliding jaw, which corresponds to the form of the rib l, above described. It will be noticed thatV the rib or plate et is of less thickness than` the shank l, so that it-can'lit into the recess 7 when thetwo jaws are brought together.V
By providing the arrangement abovedescribed the engaging jaw is provided with a vertical wall, both walls being connected by an inclined wall. The sliding jaw forms a lateral wall or surface for engagement with the end extending beyond the end of the rigid jaw, so that the nut can be readily grasped and a posit-ive purchase had to prevent the sliding of the wrench. Three bearing-surfaces are thus provided, so thata better purchase can be obtained upon the nut than is possible with an ordinary Wrench.
Another object of providing the plate is that the angles of the polygonal-sided nut will -fit snugly in the angle formed by the plate vbearing-surface 8, the shape of the jaw being substantially like the form shown in the tignre, except that it is not adjustable.
In Fig. 3 a still further modification is shown, the jaw beingidentical to that shown in Fig. 2, except that only one jaw is shown on the shank.
It will thus be seen that an efficient and durable wrench is provided, which can be manipulated and will effectively perform the service for which it is intended.
" Having described my invention., what I claim isl. A wrench comprising a shank, a rigid jaw on the end of the shank and at right angles to the inner edge of the shank, a rib or IOO shank, a plate connected to the shank and rigid jaw, one edge of the plate extending diagonally aoross the space formed by the jaw and shank, said plate being of less thickness than the jaw or shank, a sliding jaw on the shank provided with a recess corresponding to the plate so that the two j aws can be closed.
In testimony whereof I aix my signature in presence of two witnesses.
DAVID C. HINDMAN.
