WRENCH.

SPECIFICATION forming part of Letters Patent No. 439,388, dated October 28, 1890.

Application filed April 14, 1890. Serial No. 347,861. (No model.)

To all whom it may concern:

Be it known that I, ELMER S. CUSI-IMAN, a citizen of the United States, residingatDelhi Mills, in the county of VVashtenaw and State of Michigan, have invented certain new. and useful Improvements in renches, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to new and useful improvements in wrenches; and the invention consists in the peculiar construction of a rotary head having a socket or sockets and ahandle to rotate said head, and, further, in the peculiar construction, arrangement, and combination of the various parts, all as more fully hereinafter described.

In the drawings, Figure 1 is a detached perspective view of my improved wrench. Fig. 2 is a vertical central section through the wrench. Fig. 3 is an elevation showing my wrench applied to a carriage-hub.

A is a head or socket rotarily secured in the holder B. I have shown the head with two sockets a b, of different sizes, connected together by the reduced portion c,which forms a bearing for the eye (Z, formed in the holder B.

O is a handle having crank e at one end, forming the hold for the operator, and the pin f at the other end engaging in an aperture 9,

formed in the head, and preferably extending centrally entirely through the reduced portion 0.

h are notches formed in the side of the head.

The parts being thus constructed, they are intended to operate as follows: The operator taking hold of the handle B can readily secure the head upon the nut to be turned. The pin of the handle is now engaged in the aperture g, and the arm t' of the handle engages in the notch h, giving a firm hold to the head, so that by taking hold of the crank eof the handle the head A may be turned rapidly in either direction to screw on oroff the nut with which the head is engaged. It is evident that in place of forming the notch h in the head the pin f maybe squared and the aperture 9 made of corresponding shape; or, simply,-an aperture may be made in the side of the socket, as shown in dotted lines at j, in which the end of the arm "6 may be engaged.

The holder Bis preferably of greaterlength than the crank-handle C, so that the latter may not strike the hand of theoperator in its rotation. After the nut is off the stem it is held in the socket, and the tool with the nut in it may be laid down by turning the handle 0 and holder B at an angle to each other, as shown inFig. 1. This gives bearing at three points, upon which the tool rests and prevents any danger of tipping over and spilling out the nut upon the floor.

\Vhere but a single-size socket is desired, I prefer to make the handle integral with the rotary head; but where, as is usually the case, I make the head with sockets of diiterent sizes I make the handle detachable and provide the means, as described, for using it in connection with either socket.

What I claim as my invention is- 1. In a wrench, the combination, with a holder, of a rotary socketed head journaled in theholder, anda detached handle independent of the holder immediately engaging directly with the head for rotating the same, substantially as described.

2. A wrench consisting of an apertured head having sockets in its opposite ends and notches in the edges of the sockets, and a crank-handle fitted to the aperture in the head and to a notch in a socket, substantially as described.

3. A wrench consisting of a rotary head having sockets of different sizes in its opposite ends and notches in the edges of the sockets, aholder, and aremovable handle fitted in the notches in the sockets, substantially as described.

4. A wrench consisting of a rotary head having sockets CL 1) in its opposite ends of varying sizes, a reduced central portion 0, aperture g between the sockets, and notch h h in the sockets, the holder B, and crank-handle 0, having the pin f, substantially as described.

In testimony whereof I afiix my signature, in presence of two witnesses, this 8th day of April, 1890.

ELMER S. CUSHMAN.
