VEHICLE-AXLE.

SPECIFICATION forming part of Letters Patent No. 562,357, dated June 16, 1896.

Application filed July 14, 1894. Serial No. 517,526. (No model.)

To all whom it may concern.-

Be it known that I, FRANCIS G. DAVIS, a citizen of the United States, residing at Vatertown, in the county of Jefferson and State of New York, have invented a new and useful Improvement in Vehicle-Axles, of which the following is a specification.

This invention relates to that class of vehicle-axles which are provided with a sand band or collar which projects into an annular groove formed in the rear end of the hub. The invention has the object to provide simple and efficient means for excluding, so far as possible, dirt, sand, &c., from said groove and from the bearing-surfaces of the axle and box and for removing from said groove any dirt, sand, the, which may enter the same.

In the accompanying drawings, Figure 1 is a vertical longitudinal section of the end portion of an axle provided with my improvements and the hub mounted thereon. Fig. 2 is a bottom plan view thereof.

Like letters of reference refer to like parts in both figures.-

A represents the body of the axle, B the axle arm or spindle, and O the annular sand band or collar formed integrally with the axle and axle-arm at the junction of these parts. D represents the hub provided with the usual bearing box d, and E represents the screwnut which is applied to the threaded end a of the axle-arm and holds the hub on the latter.

The sand-band G has an outwardly-overhanging annular flange o, which projects into an annular groove f, formed in the rear end of the hub outside of the inner end of the bearing-box cl. This annular flange c is cylindrical on its outer and inner sides and the groove f in the hub has the same form and is entirely filled by said flange, whereby the latter excludes sand, dirt, water, 850., from the groove and from the bearing-surfaces of the box and axle-arm as far as possible. This flange c is provided on its under side with a clearing notch g, through which any sand or dirt which works into the groove ,7 can be discharged therefrom. This notch is arranged obliquely in the vertical face of the flangec, so as to slant forwardly, and the rear edge h of the notch, toward which the hub turns when the wheel turns forwardly, projects slightly beyondthe front edge h, so as to form a cutter or scraper which detaches any dirt or other solid matter in the groove and causes the same to be discharged through the rear portion of the notch which opens beyond the inner end of the hub. This cutter will also out its own way into the hub and form the annular groove in the same, if desired. The sand-band being formed integrally with the axle and spindle, and the clearingnotch and cutter being formed in this sandband, these devices are securely and permae nently attached to the axle and not liable to change their position or become loose.

The inner or discharge end portion of the clearing-notch is made flaring downwardly, as shown in Figs. 1 and 2, so that the sand or other material is readily moved toward this end of the notch by the oblique side of the notch and can readily drop out when it reaches this portion of the notch.

I claim as my invention- The combination with the axle and the spindle, of a sand-band formed integrally therewith, having an outwardly-overhanging cylindrical flange which has a vertical outer face and in its lower portion a clearing-notch, the latter extending obliquely inwardly from said vertical face and having its inner portion flaring downwardly and its Vertical rear edge projecting outwardly beyond the flat face of the band, substantially as set forth.-

Witness my hand this 3d day of July, 1894.

FRANCIS GP DAVIS.
