Description
UNITED STATES PATENT OFFICE@` ATKINS STOVER, OF NEW YORK, N. Y.
IMPROVEMENT IN SCREW-WRENCHES.
To all whom it may concern:
Beit known that I, ATKINs S'rovEE, of the city, county, and State of New York, have invented a new and useful Improvement in Screw-Wrenches; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, forming part of this specification.
My invention relates to a novel manner of operating the movable jaw of ascrew-wrench.
In the accompanying drawings, Figure l is a side elevation of a wrench with my improvement applied thereto. Fig. 2 is a longitudinal central section of the same.
Similar letters of reference indicate correspondin g parts.
A designates the bar of the wrench. B is the stationary jaw; C, the movable jaw, and D the handle. The movablejaw O is fitted to slide upon the bar A, and it has a projection, a, formed upon its rear end, through which passes a rod, E, having its bearings forits respective ends in the stationary jaw and in the back ot' the handle.
F is a worm fitted to travel upon the rod E. rIhe thread upon this worm engages with a screw-thread cut at the bottom of a shallow groove made in the back of the bar A. This groove enables the worm to sink a short distance therein, so that it will `occupy less room on the back of the bar. A slot, e, is made in the rod E in the direction of its length, and for nearly the whole ot its length, and in this projects a pin, j', which is secured to the worm F.
The movable jaw is so formedA that the worm F is partly in a cavity in its rear endthat is to say, the worm is so contined by the .jaw that it cannot be moved in either a forward or backward direction along the rod E without its moving the jaw C in the same direction, as will be understood by reference to Fig. 1, where the parts of the jaw which project upon either side of the worm are designated by the letters e and z, and the pin fand groove e are clearly shown.
The operation of this wrench is very simple and easily understood. In order to move the jaw C in either direction, it is merely necessary to revolve the rosette b upon the rod E by the thumb and forelinger in the usual manner. This causes the worm to revolve by reason of the pin f working in tho groove e, and thus the jaw is operated.
The worin is not likely to jam in any way, and with it the jaw can be moved as rzypidly, if' not more rapidly, than in wrenches where the jaw is operated by a screw-thread cut upon the rod which works in a socket made in the movable ljaw.
A wrench thus constructed possesses great strength. The rear end ot' the movable jaw is well supported, and the mode ot' operating it by the worm is very easy, and the wrench is not liable to be unduly strained as to any of its parts or impaired by continued use.
I have shown the worin F as itted upon a rod, E, located upon the back of the wrench, and I will here remark that it can be arranged upon a rod running from the forward end of the movable jaw to the handle and working iu a screwlthread cut upon the front of the bar of the wrench.
VWhat I claim as new, and desire to secure by Letters Patent, is-
1. The traveling worm F, fitted upon the rod E and working in a screw-thread made upon the back of the. bar ot' the wrench, in combination with the movable jaw O and bar A, substantially as specified.
2. The combination of the rod E, worm F, slot c, piu j', movable jaw O, bar A, and stationary jaw B, substantially as shown and described.
ATKINS STOVER.
