To LtZZ whom it may con/067%:

Be itknown that I,'THoMAs OI'IORA, of Avooa, Iowa county,Wisconsin, have invented a IIub-\lut Vrench for Vehicles, of which the following is a specification.

The device forming the subject of my present invention is intended for use in unscrewing the hub-nuts of vehicles, whereby the Wheels thereof may be removed from the axles from time to time to be greased or lubricated. l

The object of my invention is to improve this class of devices by providing means for quickly clamping the axle-nut fast to the hub-guard of the wheel, so that when the lat ter is raised from the ground and rotated in a backward direction the hubnut is carried around with it and unscrewed.

Various further advantages will appear from my construction by the consideration of the following description and the accompanying drawings.

I also propose to provide a device more simply and cheaply constructed than those heretofore invented and more conveniently operated.

My invention consists of the constructions and combinations, which will appear from the following description and are pointed out in the claims.

In the drawings hereto annexed, Figure 1 is in its lower half a side elevation and in its upper half a longitudinal section of my wrench. Fig. 2 is an end elevation thereof from the handle end. Fig. 3 is a longitudinal median section in a plane at right angles to that of Fig. 1. Fig. 4 is a transverse section on the line 4 looking in the direction of the arrow; and Fig. 5 is a view of my invention in connection with a wheel-hub, showing its application for unscrewing the hubnut.

lIy invention comprises in the main a U- shaped outer member A, having a flattened base or central portion a, in which is rotatably mounted a screw-stem l), and an inner U-shaped member B, which telescopes witln in the member A and whose base has an aperture c, through which the screw-stem b passes7 and a nut d, which engages with the threads of the stem b. The screw-stein b has on its front or outer end a handle e, riveted or otherwise fixed thereto, and within the basal portion a is set a washerf, which forms an abutment for Wings g, stamped out of the sides'of the screw-stem l), so as to prevent -blocks made separately from the members A and B endwise motion of the stem b in its socket. rIhe nut d is held against turning with respect to the member B by pressing the sides of the latter around the edges of the nut, as shown by the lines h in Fig. 4, the pressure being preferably such as to hold the nut d in position by causing the opposite angles of the nut to be enveloped by the member B, so that it forms a substantially integral piece with the member B.

The legs of the members A and B are somewhat'spread, as shown, those of the member A carrying on their ends wedge-blocks 'i and those of the member B carrying wedge- The blocks t' and may be either and riveted thereto by means of rivets k Z, as shown in Figs. 1 and 3, or they may be formed integral therewith, as shown in Fig. 5, depending on the greater facility of manufacture. The inner blocks j have oblique outer wedge-faces m, and the outer blocks i or else the inner surfaces of the extremities of the member A have cooperating oblique wedge-faces n, while the inner faces o of the extremities of the member B are made flat and parallel to the axis, so as to grip the faces of the hub-nut, and the outer faces p of the blocks i are also parallel to the axis and preferably convex to conform with the inner face of the hub-guard q, Fig. 5, which they are adapted to grip. These faces might of course be provided with corrugations or other rugosities, but this is found unnecessary, and I therefore have shown them as smooth.

Both the members A and B are preferably arched transversely along each leg, whereby the legs are stiifened and provided with maximum strength with a minimum of weight. Just above the ends of the blocks the legs-of the member B have cut in them longitudinal slots r, into whichY project tongues s, of metal, stamped in the legs of the member A and turned inwardly at right angles, as shown, thus acting as guards for the member B and preventing the member B from rotating with respect to the member A. The blocks L may, if preferred, have snugs t cast thereon, which project into the holes u left by the tongues s and abut against the bases of said tongues to prevent them from being turned back out of the slots r.

In Fig. 5 is illustrated the application of a wrench to the nut o of awheel-hub C, mounted on an axle w and having an axle-sleevex,

IOS

The instrument is inserted into the hub in such manner that the ends of member B embrace the nut o thereof and the blocks i'lie Within the hub-guard g. The handle e is then turned in a right-handed direction, so as to draw the member B within the member A, and the surfaces lm, and n, meeting one another, will by continued rotation of the handle e force the blocks inwardly and the blocks 't outwardly until the blocks i are clamped tight against the hub-guard g. The wheel C is then raised from the ground and rotated in a backward direction, carrying the nut v with it until it is fully unscrewed from the axle, when the wheel may be removed, still carrying the hub-nut o in place therein and also the hub-nut wrench. After lubricating the aXle the wheel C is then replaced and rotated in a forward direction, the nut o engaging the threads of the aXle and being screwed up into place, when the wrench may be removed. The wrench serves the purpose not simply of forming a ready means of unscrewing the nut, but also of preventing it from becoming removed from its place with relation to the wheel, and the nut and washer 'y cannot, therefore, be laid down and lost or pick up grit and dirt, which is subsequently transferred to the bearing. Moreover, the nut being held rigidly in alinement with the aXle while being screwed on cannot cross threads with the latter and become damaged, and the oil and grease is prevented from becoming smeared on the hands and clothing of slhfo operator and also on the outside of the Vhile I have hereinabove set forth the referred form of my invention, I do not imit myself to the precise mechanical details as shown, but reserve the right to all such modifications as will occur to the skilled mechanic while still embodying the spirit of my invention.

Having thus described my invention, what I clailn as new, and desire to secure by Letters Patent, is-
