SPECIFICATION forming part of Letters Patent No. 762,056, dated June 7, 1904.
Application filed February 26, 1904. Serial No. 195,387. (No model.)
To all whmn it may concern.-
Be it known that I, JOSEPH D. HILL, a citizen of the United States of America, residing at VVilmerding, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Wrenches, of which the following is a specification, reference being had therein to the accompanying drawings.
- This invention has relation to monkeywrenches, and has for its object the provision of a wrench of novel character which will be composed of as few parts as is compatible with the accomplishment of the end in view and which will be strong and durable and easy of adjustment, simple in its operation, and comparatively inexpensive in cost.
In carrying my invention into effect I have provided a toothed shank having a fixed jaw at its upper end, and on this shank I have arranged a sliding jaw carrying a swiveled arm having a short rack on its lower end that engages with the rack on the shank and two arms that extend back of the shank and serve for the pivotal attachment of a spring-pressed cam-lever, by means of which the teeth on the swiveled arms are thrust into firm contact and engagement with the rack on the shank.
In the accompanying. drawings, Figure 1 is aside elevation of the shank, the fixed jaw, and the handle of the wrench, with the sliding jaw and its appurtenant parts in section. Fig. 2 is a similar view, the handle being omitted and the movable parts of the sliding jaw being shown in that position which they occupy when the rack on the swiveled arm is out of engagement withthe rack on the shank. Fig. 3 is arear elevation. FigsA and 5 are perspective views of detached parts.
The shank 1 of the wrench and the stationary jaw 2 are formed as integral parts, and the shank has a rack 3 on its front edge, the teeth of said rack beinginclined upwardly, as shown. The handle 4 is of the usual'character and is secured to the shank 1 in the ordinary or any desired manner. 1 The sliding jaw 5 is formed with an opening therethrough for the reception of the shank 1, and upon the lower side of the sliding jaw is a circular recess 6, which receives the circular head 7 of a depending arm 8, which has teeth 9 formed on its inner side, near the lower end thereof, which teeth when the sliding jaw is to be fixed in position engage with the teeth of the rack on shank 1. In order to allow of the circular head 7' of the arm 8 being introduced into the circular recess 6, the head is cut away, as indicated at 10, so that when the arm is swung into position, as shown in dotted lines in Fig. 1, the circular head may be introduced into the circular recess. When, however, the arm 8 is swung back to its vertical position, the circular head will be socketed in the circular recess and cannot be withdrawn therefrom. The arm 8 is formed with two projecting cars 11 11, which have holes 12 12 near their ends, that receive a fixed pin 13. A lever 14:, which has two cams 15 15 formed on its bifurcated inner end,is rotatably mounted on the pin 13, and the pin is flattened on one side, as shown at 16, to afford a bearing for a spring 17, thatis arranged between the cams 15 15 and riveted to the lever 14 at 18.
The operation of my device is as follows: The wrench being held in the handin the ordinary manner, the lever 14: is swung around to the position shown in Fig. 2, which releases the teeth 9 of the depending arm 8 from engagement with the rack 3 of the shank. In this position the sliding jaw can be moved up and down to any desired position on the shank. When the sliding jaw has reached the desired position, the lever 14 is depressed to the position shown in Fig. 1, the spring 17 in this position resting on the flat surface 16 of the pin 13 and serving to maintain the lever in the position shown in Fig. 1. .To release the teeth 9 from their engagement with the rack 3, it is only necessary to push upwardly on the lever sufficiently to overcome the resistance. offered by the spring to the upward movement of the same, and when the lever has reached the position shown in Fig. 2 the sliding jaw can be moved up or down on the shank, as desired.
Having described my invention, I claim 1. In a wrench,the combination with a shank having a fixed jaw and a rack on one of its edges, of a sliding jaw embracing the shank,
with a flattened surface, a lever swiveled on said pin and having cam-shaped bifurcated ends and a spring attached to the jaw, pro- 5 jecting between the ends thereof and bearing against said pin.
In testimony whereof I affix my signature in the presence of two witnesses.
JOSEPH D. HILL.
