AXLE-NUT WRENCH.

SPECIFICATION forming part of Letters Patent No. 613,613, dated November 1, 1898.

Application filed December 24, 1897. Renewed October 4,1898. Serial No. 692,651. (No model.)

To aZZ whom it may concern:

Be it known that I, DANIEL WARNER, a citizen of the United States, residing at Bronson, in the county of Branch and State of Michigan, have invented a new and useful Axle-Nut Wrench, of which the following is a specification.

The invention relates to improvements in axle-nut wrenches.

The object of the present invention is to improve the construction of axle-nut wrenches and to provide a simple, inexpensive, and efficient device adapted to engage an axle-nut and the hub of a wheel and to adjust itself automatically to the size of the nut and the opening of the hub and capable of firmly gripping the parts, so that the nut may be screwed on or off the axle by rotating the wheel.

Another object of the invention is to provide a device which will prevent an axle-nut, after it has been unscrewed from the axle,

from dropping upon the ground.

The invention consists in the construction and novel combination and arrangement of parts, as hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure l is a perspective view of an axle-nut wrench constructed in accordance with this invention and shown engaging a hub and an axle-nut. Fig. 2 is a perspective view of the wrench detached.

Like numerals of reference designate corresponding parts in both figures of the drawlngs.

1 designates an axle-n u't wrench comprising a pair of similar jaws 2 and a substantially U-shaped spring 3, having diverging sides which are adapted to be compressed when the device is applied to a wheel, as illustrated in Fig. 1 of the accompanying drawings, whereby the jaws will be caused to engage and grip the interior of the hub firmly. The spring is constructed of resilient material sufficiently stout to produce the necessary pressure or frictional engagement between the jaws and the hub 4.

Each jaw, which is constructed of suitable metal, is substantially segmental, being pro vided at its straight edge with a central V-shaped notch 5, adapted to engage the corner of a nut, as shown in Fig. 1, and the curved edge or periphery of the segmental jaw is provided at opposite sides of the spring 3 with teeth 6 and 7, shouldered in opposite directions and adapted to bite the inner face of the hub. One set of teeth positively engages the hub and prevents the device from slipping when the wheel is rotated in one di rection, and the other set of teeth secures the necessary engagement of the parts when the wheel is rotated in the opposite direction.

The wrench is capable of adjustment to suit the diameter of the hub and the size of the nut, and after the latter has been unscrewed from the axle the wrench prevents it from dropping into the dust.

The invention has the following advantages: The axle-nut wrench is exceedingly simple and inexpensive in construction and is adapted to adjust itself automatically to the hub of a wheel and an axle-nut, and it is capable of engaging both the nut and the interior of the hub, so that the former may be screwed on or 0E its axle by simply rotating the wheel. The device also retains the nut in the hub and prevents the same from falling upon the ground when removed from the axle. The

arrangement of the sets of teeth secures the necessary engagement between therperipheries of the jaws and the interior of a hub.

Changes in the form, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

What I claim is 1. A device of the class described comprispair of segmental jaws connected to the arms In testimony that I claim the foregoing as of the spring and provided at their periphmy own I have hereto aifixed my signature in eries with teeth, the teeth at one side of each the presence of two Witnesses.
