GEORGE R. SLAGLE, ARTHUR N. GARNER, AND WILLIAM R. RUSHIN, OF BRASHEAR, TEXAS, ASSIGNORS OF ONE-FOURTH T0 J. Ill/[(DAVIS, OF BRASHEAR, TEXAS.

WRENCH.

Specification of Letters Patent.

Patented Oct. 26, 1920.

To all whom it may concern:

Be it known that we, GEORGE E. SLAGLE, ARTHUR N. GARNER, and VILLIAM R. RUSHIN, citizens of the United States, residing at Brashear, in the county of Hopkins and State of Texas, have invented certain new and useful Improvements in Wrenches, of which the following is a specification.

This invention relates to improvements in wrenches and in such connection it relates more particularly to a device of this character by means of which parts of machinery ordinarily difiicult of access may be easily reached.

The primary object of the invention is to provide a device of this description which can be effectually used in removing or replacing the nut or nuts on a fourth connecting rod of a Ford motor in order to remove or replace the rod, such rod being in a position diflicult to reach by an ordinary wrench.

Another particular object and feature of the invention lies in the arrangement of the Worm gear drive for rotating the wrench socket.

The invention will be more fully understood from the following description, taken in connection with the accompanying drawings forming part hereof, in which Figure 1 is a top or plan view of a wrench embodying the invention.

Fig. 2 is a side elevational view.

Fig. 3 is a side elevational view taken from the side opposite to that shown in l ig. 2, the handle and crank partly broken away. v c

Fig. 4 is a detail view partly in section, the section taken on line 4-4 of Fig. 1, and

Fig. 5 is an elevational view of the gear wheel, the View! taken from the bottom thereof.

Referring to the drawings, 1 represents the top plate and 2 the bottom plate of the wrench which are formed integral with a handle 3, the handle extending in an oblique direction from the plates 1 and 2, forming the head. Between the two plates 1 and 2 is arranged a gear wheel 4, the hub 5 of which abuts the top and bottom plates, allowing the gear wheel to travel freely, the plates being connected by the supports 66.

The gear wheel 4 has its teeth disposed at an oblique angle with respect to the periphery of the wheel in order to receive the spiral screw or worm 7 of the gear 8. The shaft 11 of the worm gear has its bearings 9 and 10 connected to the top and bottom plates 1 and 2; consequently the gear and its shaft 11 are angularly disposed with respect to the gear wheel 4 so that they may properly mesh. The shaft 11 is extended slightly beyond the end of the wrench handle 3 and bent to receive a handle 12.

A socket 13 formed integral with a small shaft 14 traverses the wrench head and is secured by a cotter pin as shown. This socket is square at approximately the center of its shaft 14 to fit the square opening 15 in the gear wheel 4, and may be constructed to fit any size or shape of nut, a socket for a hexagonal nut only being shown.

We are aware that wrenches of this type are numerous and do not claim the idea in any broad sense, but what is claimed is- A wrench of the character described, comprising in combination a frame and handle, a shaft provided with a worm, said shaft spaced apart from the handle, said worm disposed diagonally across the side edges of the frame and meshing with a gear, a. socket, the shank of which traverses the gear and the sides of the frame, said worm and shaft adapted to directly rotate the gear and socket.

In testimony whereof they have signed their names to this s ecification.
