IMPROVEMENT IN WRENCHES.
Specification forming part of Letters Patent N 0. 208,05 7, dated September 17', 1878 application filed August 6, 1878.
To all whom it may concern:
Be it known that I, AUGUST BECK, of the city, county, and State of New York, have invented a new and Improved Wrench, of which the following is a specification:
Figure 1 is a side elevation of my improved wrench as applied to a ratchet-drill, a part being broken away to show how the wrenchbush is held in position. Fig. 2 is a plan view, partly in" section. Fig. 3 is a detail view of a bushing for adapting the wrench to bolts and nuts. Y
Similar letters of reference indicate correspondin g parts.
My invention consists in a split ring or friction-strap having at one side of the split an arm that is pivoted in a lever-handle, and having at the other side of the split an inclined plane, which is acted on by a pin in a short double arm that projects from the lever-handle. The wrench is provided with a split ring, whose elasticity expands and causes the handle to be retracted, so as to loosen the gripe upon the object held.
In the drawing, A is a split ring formed on the end of an arm, B, which is pivoted in the leverhandle 0, the said leverhandle being grooved longitudinally to receive it.
The arm B is at one side of the split in the ring, and an inclined plane or wedge, D, projects from the-ring at the opposite side of the split, and is engaged by a pin, a, that passes through a double arm, I), which projects from I the pivot end of the lever-arm O at right angles and straddles the inclined plane or wedge A spring, 0, is secured to the longer or free end of the arm B, and. presses against the lever-handle (3, throwing the wedge D away from the pin a.
The split ring A is fitted to any object which it is desired to turn, such as a drill-stock, as shown in Fig. 1, or the bushing shown in Fig. 3, which is adapted to the heads and nuts of bolts. A forward movement of the hand-lever brings the pin a into engagement with the inclined plane D, and thus contracts the ring, when a further forward movement results in turning the object to which the split ring is fitted.
This wrench may be used for turning in a right or left handed direction, and it I may be applied to drill-stocks and jack-screws.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combination, with the recessed handle 0, having double arm I) and cross-pin a, of the pivoted spring-pressed arm B, provided with spring-ring A, and with a wedge on one of the open ends of ring opposite to the arm B, as shown and described.
AUGUST BECK.
