JOHN T. SULLIVAN, OF ST. LOUIS, MISSOURI.

VEHICLE-WRENCH.

Specification of Letters Patent. Patented July 23, 1912. Application filed October 2, 1911.

Serial No. 652,244.

To all whom it may concern:

Be it known that I, JOHN T. SULLIVAN, a citizen of the United States, and resident of St. Louis, Missouri, have invented certain new and useful Improvements in VehiclelVrenches, of which the following is a specification containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to vehicle wrenches, especially adapted for use in removing and replacing the nuts of vehicle-axles, in applying lubricant to the axles.

The object of my invention is to provide an improved vehicle wrench by means of which the nuts of axles may be removed and replaced without the necessity of the operator touching the nut with his fingers, to prevent soiling of the fingers by the grease and grime usually present upon axle-nuts.

A further object is to provide an improved wrench of this class which shall be simple and durable in construction and operation, and yet highly efilcient for the purpose mentioned and for all the purposes to which an ordinary monkey wrench is adapted.

My invention consists in the novel construction and combination of parts hereinafter described and specifically pointed outin the appended claims.

Referring again to the drawings: the figure is a perspective View of a wrench embodying my invention, applied to a common vehicle-wheel; portions of the latter unnecessary to be shown being broken away.

My improved wrench is constructed with the usual fixed jaw 1, sliding jaw 2, threadedshank 3 and shank nut 4, for an obvious purpose. Projecting at right-angles from the shank 5 in a direction parallel with the said fixed jaw 1, is an arm 6 through which is threaded a thumb-screw 7. Pivotally attached to the outer end of said shank 5, by means of the pivot-pin 8, is a handle 9 which is limited in its movements by the form of the common hinge or pivot connecting it to said shank.

The numeral 10 indicates the wheelspokes; 11 the hub-flange; and 12 the axlenut.

The operation is as follows: The operator places the wrench-jaws 1 and 2 upon the axle-nut 12, as shown, so that the arm 6 will project upon the exterior of the hub flange 11; then the thumb screw 7 should be turned to force the inner end of said thumb screw into contact with the said hub flange, in order to secure the wrench firmly in position upon the said flange; after which the handle 9 should be thrown inwardly until it occu pies a position substantially at right angles to the said shank 5, and until it is projected between two adjacent spokes 10, after which the entire wheel, wrench, and axle-nut may be rotated to remove or replace the axle-nut, as may be desired, and all this may be done without the operators fingers becoming soiled by grease or grime from the axle-nut.

It will, of course, be understood that in order to rotate the parts as above described it will be necessary to raise the wheel from the ground, which may be done by means of a common lifting-jack in the ordinary manner.

I claim:

1. The improved vehicle wrench comprising the usual opposed screw-adjusted jaws, a shank, an arm projecting laterally from said shank and permanently fixed thereto in a position parallel with said jaws, a thumb screw threaded through said arm to engage the hub flange, and a handle pivotally connected to said shank and adapted to be swung in between the wheel spokes.

2. The improved vehicle wrench, comprising a fixed jaw, a sliding jaw, a threaded shank connecting said jaws, a shank-nut, a fixed shank, an arm projecting at right angles from the latter in a direction parallel to that of the said jaws, a thumb screw threaded through said arm so that its inner end will engage the outer periphery of the hub flange, and a handle pivotally attached to the outer end of said main shank and adapted to be swung in between the wheel spokes.

In testimony whereof, I have signed my name to this specification, in presence of two subscribing witnesses.

JOHN T. SULLIVAN. Witnesses:

E. L. WALLACE, N. G. BUTLER.
