T0 ctZZ whom it may concern.-

Be it known that I, GEORGE W. AMos, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in AxleNnt Attachments; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, in which- Figure 1 is an axial section of the front portion of a vehicle-hub to which my improvements are adapted; Fig. 2, a transverse sec tion' of the same at line x :0; Fig. 3, a similar View at line 3/ 1 Fig. 4, a detail elevation of the parts in an engaged position, the hub and band being shown in section; Fig. 5, a similar View of the parts in a disengaged position; Fig. 6, a face view of the axlennt; and Fig. 7 an elevation, partly in section, of a modified arrangement of parts.

Similarletters ofreference indicate like parts in the several views.

My invention relates to that class of axle nut attachments in which a wrcnclrhead is arranged to move in the hub-band and engage the axle-nut, so that a rotation of the wheel will cause the axlenut to screw upon the threaded axle end, or off from the same, as desired; and my present improvement has for its objects, first, to provide an improved construction of axle-nut, whereby the screwing or jamming too tightly of the same upon the axle end is prevented in a very effective manner; second, to supply a simple, cheap, and durable means for automatically disengaging the wrench-head from the axle-nut after the same has been turned or screwed up to its proper position on the axle end; third, to furnish means for securely holding the said wrenchhead in a position out of engagement with the axle-nut after the same has been applied, and, fourth, to afford a simple and effective means for locking the cover'eap of the hub-band from disengagement after it has been screwed into place.

To enable others skilled in. the art to which my invention appertains to make and use the same, Iwill now proceed to more particularly describe the mechanism employed to attain the above-mentioned objects.

Referring to the drawings, Arepresents one end of the axle, threaded in the usual manner; 13, a portion of the hub; O, the outer hubbund. and I) the axle-nut, provided with the usual washer-cavity for the axle-washer a.

In the present improvement this axle-nut is provided with one or more projecting lugs, d, parallel with its axis, and which are engaged preferably by a wrench-head, as hereinafter described, in applying or removing said nut to or from the threaded axle end. The forward or applying faces, (1, of such lugs are made beveled or inclined, as shown, so that with the increased resistance met with as the axle-nut reaches its proper position on the threaded axle end said inclined faces will cause the wrench-head tomove longitudinally out of engagement therewith. The rear or removing faces, 0, of the lugs will be made straight, or withouttheabove-described bevel, as a positive attachment between the nut and its operating wrench-head is desirable in the operation of unscrewing the axle-nut.

This improved form of nut is adapted for use in connection with any suitable form of wrench-head that will engage its longitudinally-projecting lugs; yet preference is given to the construction of parts shown in the drawings, as providing a self-contained antomatieally-opcrating mechanism for applying and removing the nut when required. in this E rep resents thewrcnch head,adapted to move longitudinally in the hub-band and caused to turn therewith by means of guide-splines 0 on the inner periphery of the hub-band, that are embraced by lugs on the wrench-head, as shown. Any other equivalent means for connecting said wrench-head in a longitudinallyadjustable manner to the hubband may be employed, instead of that above described, without departing from the spirit of my invcntion.

The wrenclrhead E is provided with longitudially-projecting lugs c e, counterparts of the 9 axle-nnt lugs d d, and with similarly-formed faces e 6*, as shown.

The longitudinal movement of the wrenchhead E will be sufficient to bring the lugs e ontirely out of the path of the lugs d, and the wrench-head isheld in either an in or out position by the following means:

IOC

F are radially-moving bars,arranged to slide in the fore part of the wrench-head and having an outward tendency imparted to them by springs f, as shown. These bars,which I term spring latch-bars, bear against the inner periphery of the hub-band, and in their path are arranged inwardly-projecting V-shaped lugs 0 upon the said hub-band. The inclined faces of these lugs constitute stops for retaining the wrench-head in the required position until overcome by a superior force. Such force is supplied in moving the wrench-head into engagement with the axle-nut, when it is desired to remove the same, by the pressure of the finger or other suitable means inserted through a central opening in the cap or cover G of the hub-band. Said force is supplied when the wrench-head is to be forced out or disengaged by the inclined faces d c ofthe lugs d and c after the axle-nut has reached its proper position on the'axle end.

It is evident that the relativepo'sition of the parts above described can be modified and transposed without affecting the working of my improvement. Forinstance, the yielding contact or engagement formed by the inclined faces of the nut-lugs and the wrench-head may be transposed to any other suitable point between the nut and the point of frictional resistance caused by the latch-bars F, preferably between the wrench-head and the hubband, as in such case the guide-splines 0 can be employed to form one member of the aforesaid yielding contact provision by arranging them in a spiral or inclined direction to the axis of the parts. Again, the minordetails of construction may be similarly varied.

In Fig. 7 I show one of such modified arrangements, in which springs H take the place of the lugs c, andfixed lugs F the place of the spring latch-bars F, to effect a like result to that before described.

In another modified arrangement (not illus trated) the lugs c c are replaced bya central stem projecting inwardly from a wrench-cap and having inclined projections on its sides similar to the lugs c, that are engaged by a pair of sprin g-bars substantially similar to the spring latch-bars F, other than that their springs are arranged to force them inwardly against the inclined faces or sides ofthe aforesaid central stem.

The hub-cap G screws'into the hub-band in the usual manner, and is held from turning by pin projection or project-ions 9 upon its inner face being engaged by corresponding recesses, e", in the outer face of'the adjustable wrench-head E, when the same is in its outer position, which is its normal position during the use of the vehicle.

I is a rubber or other cushion inserted in the cap G to form an abutment for the wrenchhead E, to prevent rattling of the parts in use.

NVith my improvement the nut is always held within the cavity of the hub in proper position to receive the threaded axle end. The

leakage of the lubricant is entirely prevented, as well as the soiling of the hands of the operator, in removing or applying the wheel; but what is of greater moment is the prevention of any liability to breakage due to the amming or binding of the same, which, with my improvement, is automatically relieved before a point of danger is reached.

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

1. In an axle-nut attachment, substantially as set forth, an axle-nut provided with an applying lug orlugs having the inclined face (1, substantially as set forth.
