HENRY P. TRYON, OF SEDALIA, MISSOURI.

SOCKET-WRENCH.

SPECIFICATION forming part of Letters Patent No. 494,994, dated April 4, 1893;

Application filed January '7, 1893. Serial No. 457,611. (No model.)

To all whom it may concern:

Be it known that I, HENRY P. TRYON, a citizen of the United States, residing at Sedalia,

My invention relates to that class of socketwrenches employed for removing the taps or nuts from the axles of vehicles during an oiling of the bearings. A

The objects of my invention are to provide a cheap and simple wrench, so constructed as to be readily applied to various sizes of taps or nuts and adjusted to such sizes, and to retain or hold such tap or nut during a revolution of the wrench and a consequent loosening of said tap or not and its removal; and furthermore to be capable of being laid upon the ground or other convenient place and to obviate contact of the nut with said ground, and thus avoid dust and grit adhering thereto.

With these various objects in view the invention consists in certain features of construction hereinafter specified and particularly pointed out in the claims.

Referring to the drawings: Figure l is a perspective view of a wrench constructed in accordance with my invention. Fig. 2 is a transverse sectional view of the same. Fig. 3 is a sectional view of the wrench applied to the tap or nut of an axle, the hub and a portion of the wheel being shown.

Like numerals of reference indicate like parts in all the figures of the drawings.

In carrying out my invention I employ a disk-shaped head 1, which is preferably cast and formed integral therewith upon its back is a curved handle 2 designed to form a ready grasp for the hand of the operator. The face of the head 1 or that side thereof opposite to which the handle is located is provided with a rectangular recess or socket 3 around which there is integrally formed with the head a rectangular external or superficial flange 4. It will be observed that the head, flange, and handle may be, and preferably are, formed in a single piece or casting, though if desired, they may be independently constructed or formed and assembled. The working-face of the head it will be observed,is preferably flat or plain and hence is adapted when the flange is introduced into the end of the hub to take over thehub-band regardless of the construction of the latter andlie flat against the same. The head 1 near its upper face is provided transversely with a radial perforation or bore 5, and communicating with the same is an opening 6, formed in the said face. The perforation or bore 5 communicates with the interior of the socket and in said bore and extending into the socket, is in this instance, a rotatable crank -shaft 7 terminating at its outer end in a handle 8 by which it may be operated. The crankshaft is threaded between its ends and passes through a nut or bearing 9 located in the opening 6 in line with the perforation 5. The inner end of the crankshaft is provided with a head 10, and the same fits between a pair of clamping-plates 11, whose opposite edges have lugs 11 for enga ing recesses 3 formed in the sides of the socket, which after being assembled are socured rigidly together as shown. It will be seen that by revolving the crank-shaft the clamping-plate or follower will be operated within the socket, and hence the width of the socket reduced or increased to accommodate it to the various sizes of taps or nuts employed for the ends of axles.

This completes the construction of the device, and its operation is as follows:In order to remove a wheel the wrench is grasped in one hand of the operator and introduced face foremost to the end of the hub the plain face of the hub resting against the outer end or edge of the hub-band and the flange takin g into the hub-band so that the tap or nut is received by the socket. It is now simply necessary to rotate the crank-shaft so as to feed the follower or clamping-plate toward the nut and thus embrace the same. Now by operating a wrench in the ordinary manner it will be seen that the nut maybe withdrawn and the same will be clamped securely in the wrench. The wrench having simply a socket, that is a nut-receiving opening having closed sides, ends and bottom, it will be obvious that the wrench may rest upon the ground, or any other point, and all possibility of the nut coming in contact with the dirt or dust will be avoided, so that grit, &c., will not adhere thereto and serve subsequently when the nut is re-applied to cut or destroy the bearing or threads. By curving the handle of the wrench it will be observed that the same may be'readily grasped or picked up when lying upon the ground.

From the foregoing description in connection with the accompanying drawings it will be seen that I have provided a simple and convenient wrench designed to remove or apply nuts of varioussizes from and to the ends of axles, and that said Wrench forms a convenient holder for retaining the nuts after such removal and prevents them from coming in contact with grit and other foreign substances, which is undesirable or'which is liable to impair the threads or hearing of the axle; furthermore that the/said wrench may be convenientlyhandled and retrieved from the ground when occasion may require.

Having described my invention, what I claim is 1. In a wrench of the class described, the combination with the disk or headprovided upon its back with a handle, and upon its face withasocket having a closed lower'end and a flange encircling the socket'and extend ing from the head, of a transverse crank-shaft threaded in a bearing inthe head and proat its-inner end in a head,-and a clampingplate secured loosely' to the head and located within the socket, substantially as specified.

2. In a wrench of the class described, the combination with the head or disk having a plain upper face, a socket formed therein and provided with a bottom, a radial threaded bearing in the head a flange encircling the socket and extending from the face said socket'having recesses in its opposite sides, a follower or clamping-plate mounted in the socket, and lugs formed on the sides of the plate and engaging the recesses, of a crankshaft j ournaled' inth'e' bearing and loosely engaging the clamping-plate and terminating at its outer end in a er'ank-, said shaft having serewthreads engagingeor respendtn threads in the hearingand thecurvedhandle extendihgfrOliI the hackof tlieliead, substantially as specified; y

In testimony that I claim the foregoin'g as my own I have hereto affixed my signature in the presence of two witnesses.

HENRY P; TRYON.
