IMPROVEMENT IN VEHICLE-WHEEL HUBS.

Specilication forming part of Letters Pat-ent No. 2049903, dated June 1S, 1878; application tiled January 11, 1878.

To all whom it may concer-u:

Be it known that I, JOHN LANE, of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Vehicle-Wheel Hubs, and axle-boxes connected therewith, which improvement is fully set forth in the following specification and accompanying drawings, in which- Figure l gives a view of my improved axlebox B, having extensions K K and grooves g g. Fig. 2 gives a sectional view of the hub A, on aline through the center of the hub, from end to end, showing the inside construction of the same. Fig. 3 gives a view of the hub A, with my improved axle-box B attached, showing how the axle-box is secured in its position with the end extensions K K projecting beyond the ends of the hub.

My invention relates to that class of vcheap vehicle-wheels having a cast-iron hub and a removable axle-box, known as agricultural Wheels, and used on sulky-plows, and other implements in which sand and grit are liable to get into the box on the axle, and between the axle-box and hub, cutting the axle-box out quickly, and requiring anew axle-box to replace the worn-out one.

My invention consists in a new and improved axle-box of peculiar construction, and a wheel-hub of such construction as to have the axle-box united and combined therewith,

ing a shoulder, against which the heads of bolts h h rest. It is provided with grooves g g, extending from the shoulder at W some distance toward the other end of the axle-box, as shown in the drawing. The axle-box B is considerably larger at the shoulder W than at Y, corresponding in diameter to the difterent diameters of the bore of the hub at the two ends, as shown. rIhe grooves g g receive the body of the bolts h h, by which the axlebox B is secured to the hub A.

The inside of the axle-box B may be of any ordinary construction for itting and revolving on either tapering or plain bar axles, and may be enlarged in the center or cut away between the bearing-seats at W and Y, either on the outside or inside.r`

A is the hub, made of cast-iron, of any ordinary construction in its outside dimensions, and may be provided with either wooden or iron spokes, as desired. Fig. 3 shows how wooden spokes a are set and placed in the mortises a', between the supports f f', and also how iron spokes b b are set and placed zigzag by setting each alternate spoke at opposite-ends of the hub, bracing each other from the supports ff.

The hub A has its bore larger at one end than at the other, tapering from end to end, and of such construction as to provide seats e e therein, fitting the axle -box B. I prefer to enlarge the bore in the center of the hub between the seats c e', forming a recess, s, making the hub lighter, and to insure the seating of the axle-box at both ends of the hub. a: w are holes in the rim of the hub, through which the bolts h h extend when securing the axle-box to the hub.

The axle-box B being placed in position on the hub A, the bolts h h are inserted in the grooves g g, and extend through the holes m. rIhe heads of the bolts rest against the shoulder W, and mits a a are seated outside against the end of the hub, rmly securing the axlebox B on the hub A. Should the parts wear loose, they can be again tightened up by screwing down the nuts n n on the bolts h h, drawing the axle-box farther into the hub. Should the axle-box wear out on the axle, by simply removing the bolts h h the axle-box can be removed and replaced by a new one.

The extensions K K may be covered with broad sand-caps on the collars, and washers may be placed on the axle to keep the sand and grit from getting between the axle and axle-box Without interfering with the free revolution of the box on the axle. y

I am aware that it is not new to use a conical or tapering axle-box in a hub; also, that bolts have been used to secure a box to a hub. Such I do not claim.

What I do claim as my invention is- 1. The hub A, having a central conical perforation and seats, e e', and having combined thenewith an axle-box, B, having grooves g g and shoulder W between the extensions K K', and united to the hub with bolts h h, as shown and described.

2. The hub A, having a central conical perforation and seats, e e', as shown, and having the recess s formed between the seats e e', and having the holes m w' in the rim of the hub, as shown, all arranged as and for the purpose set forth.

3. The axle-box B, with eXtensionsK K', Qpen grooves g g on the outside, and shoulder W, the extension K projecting outward beyond the shoulder W, as shown, all arranged as and for the purpose set forth. i

JOHN LANE.
