VEHICLE NUT-WRENCH.

SPECIFICATION forming part of Letters Patent No. 642,391, dated January 30, 1900.

Application filed July 31, 1899- To @ZZ whom it may concern:

Be it known that I, JACOB EDWARD VAN- NOTE, of Lakota, in the county of Nelson and State of North Dakota, have invented a new and Improved Nut-Wrench, of which the following is a full, clear, and exact description.

This invention has for its object to provide a nut-wrench of simple novel construction Y which is specially well adapted for screwing the nuts of Vehicle axle-spindles upon and from the same; furthermore, to so construct the improved wrench that it will receive and clasp spindle-nuts of different sizes, so that they will remain engaged .with the wrench when detached from their normal position,and thus be retained for convenient replacement upon the vehicle-spindles when this is desired.

The invention consists in the novel construction and combination of parts,as is hereinafter described, and defined in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure lis a perspective view of the improved wrench. Fig. 2 is an end View of a main portion thereof seen in direction of the arrowx in Fig. 8. Fig. 3 is aplan view of the same, showing the end of the nut-clamp drawn outward. Fig. 4 is a sectional plan view of the portion of the wrench shown in Fig. 2 substantially on the line 4 4 in said figure, and Fig. 5 is a longitudinal sectional view of the improved wrench-head substantially on the line 5 5 in Fig. 4.

On the elongated handle-bar 6 a hollow head-piece 7 is integrally formed and disposed transversely thereof, as indicated in the drawings. 'lhe head-piece 7 is represented as rectangular in cross-section, but may have a different angular foundation-hexagonal, for example, if the nuts to be operated upon have such a peripheral form. The rectangular aperture in the head-piece 7 has opposite sides thereof parallel with each other, and in said box-like head-piece the nut-gripping socketpiece 8 is loosely located.

As shown, the socket-piece 8 comprises, in part, a four-walled thimble adapted to slide loosely within the head-piece 7 and having on two opposite sides thereof like arms 8,

Serial No. 725,615. (No model.)

projected in parallel planes at the same end of the socket-piece. The arms 8a are joined at their outer ends by a preferably-circular cap-flange 9, having a convex outer farce, and said cap-flange serves to limit the slidable movement of the socket-piece 8 in the hollow head 7 in one direction, as indicated in Figs. 1, 4, and 5. d The arms 8a are longitudinally slotted near their transverse centers and for a portion of their length, these slots b being oppositely positioned in planes parallel with the edges of the arms, and a cross-bar 10 loosely engages with each slot b, passing through perfor-ations in the opposite sides of the hollow head-piece 7, wherein the ends of the cross-bar are respectively fixed, said crossbar preventing a complete removal of the socket-piece 8 from the hollow head 7.

The inner sides of the socket-piece 8 liare outwardly to an equal degree, thus affording an inwardly-contracting socket-hole, which will receive nuts of varying dimensions. Each side wall of the socket-piece 8 is slitted, as at c, from the outer .edge inwardly near the center of width thereof, and the sides of the socket-piece from which the arms 8a project are slitted at points which adapt said slits to merge their inner ends in the adjacent ends of the slots b.

It willbe seen that the slits c in the socketpiece 8 andslots b in the arms 8a coact to render A the walls of the socket-piece measurably resilient, and thus adapt said walls to spring apart slightly upon the forcible insertion of a nut within the socket-piece, which will cause the nut to be gripped thereby and held sufficiently tight to prevent it from falling out of the socket-piece when the nut is within the same.

In use the nut of a carriage or wagon axlespindle that is to be removed from the spindle is introduced within the socket-piece 8, while the handle-bar 6 is grasped with one hand of the operator. Pressure of the other hand is applied to the cap-flange 9 and the nut thus bedded in the socket-piece 8. The handle-bar 6 is now rotated in a proper direction to remove the spindle-nut while pressure is maintained upon the cap-flange 9, this operation resulting in the easy removal ICO piece 8 for return to the threaded end of the axle-spindle when this is desired.

At the opposite end of the handle-bar 6 an enlargement is formed, wherein two lateral notches d and an end notch e are formed, thus providing an ordinary open-end Wrenchhead for use on nuts or bolt-heads that the notches will fLt upon.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination with a handle-bar, and a hollow head thereon angular in cross-section, of a socket-piece loosely fitting against the interior walls and angles of said head, and held to slide therein, said socket-piece having a cap-flange on one end for its manipulation, and an angular tapered sockethole extending therein from the opposite end, the side Walls of which are slitted to render them resilient.

2. The combination with a handle-bar, and

a hollow head thereon angular in cross-sec! tion, of amatingsocket-piece having opposite arms extended at one end, and held to slide in the hollow head by a cross-pin which loosely engages slots in the arms, and is secured at its ends in the hollow head.

The combination with a handle-bar, of a hollow head-piece on an end of said handlebar rectangular in cross-section, a socketpiece loosely fitting in the Ahollow head and having a tapering socket-hole therein, the Walls of which are slitted to render them resilient, two opposite arms having longitudinal slots and extending at one end of the socket-piece, a cap-liange joining outer ends of said arms, and a cross-pin passing through the slots of the arms and fixed by its ends in opposite walls of the hollow head.
