WRENCH.
SPECIFICATION forming part of Letters Patent N0.-62,2,428, dated April 4, 1899.
Application filed August 19,1898. Serial N0- 689,063- (No model.)
To all whom it may concern.-
Be it known that I, CHARLES CARROLL HAR- POLD, a citizen of the United States, residing at Italy, in the county of Ellis and State of Texas, have invented a new and useful WVrench, of which'the following is a specification.
My invention relates to wrenches, and has for its object to so construct the same that they can be operated upon a nut at any angle in which it may be found.
Figure 1 is a plan view of my complete wrench. Fig. 2 is a side view of the handle, showing the several sockets. Fig. 3 is a plan view of a steel plate used in connection with the sliding jaw K. Figs. 4 and 5 are perspective views, respectively, of a socket-wrench and screw-driver which may be substituted for the wrench shown in Fig. 1.
A represents a wrench-handle having at one end a projecting or semicircular head A, provided with a recess B and a series of tapering sockets B, extending at different angles from such recess to the curved face of the head.
D represents a Wrench, one of whose jaws K terminates in a tapering shank 0, adapted to fit and be held in any one of the sockets B of the head B and secured in place by a thumb-screw H. The wrench D may be readily reversed in position and adjusted to operate on taps or nuts at diiferent angles by inserting its shank in different sockets. jaw K of the wrench D has a pin F, having a threaded end, and a flat bar E firmly secured thereto. The jaw K of the wrench slides upon this bar and pin,and a swelled head upon the plate E prevents the separation of these parts. The thumb-nut I has a rim or flange The at its inner end, which rests in a countersunk recess in the jaw K. The U-shaped plate V is also sunk in the face of the jaw K and serves to retain the adjusting thumb-nut upon the threaded pin F. By turning the thumbnut upon the pin the jaw K will be moved toward or from the stationary jaw K. The plate V may be secured in place by a screw or any other suitable means. Upon the outer face of the jaw K is a projection or ridge which protects the thumb-nut and strengthens the jaw.
N and L (shown in Figs. 4 and 5 of the drawings) are respectively a simple form of socketed wrench and screw-driver which may be substituted for the wrench D where the size of the latter renders it unsuitable for use.
Having fully described my invention, what I claim is 1. The combination. of a handle having a projecting or semicircular head provided with .a series of sockets arranged at different angles, with awrench having a shank to engage any of the sockets, and means acting within a recess in the head common to all the sockets,for holding the shank secured,as set forth.
2.'-A wrench having fixed jaw K provided with guide-plate E and adjusting-pin F,a jaw K sliding on the plate and pin, a thumb-nut threaded on the pin and having a flange conntersunk in the jaw K and a U shaped plate to retain the thumb-nut in place, all combined as set forth.
CHARLES CARROLL HARPOLD.
