`VEHICLE-WHEEL HUB.

SPECIFICATION forming part of Letters Patent No. 225,498, dated March I6, 1880.

I Application led March 31, 1879.

To all whom it may concern Be itknown that I, GiLBEET ToZEE, of A 1 Vence being had to the accompanying drawings, in which- Figure l is a central longitudinal section of the improved wheel-hub; Fig. 2, a central cross-section thereof, showing also a part of the spokes in place; Fig. 3, an inner end view of the hub; Fig. 4, a central section, in the plane of the wheel, of the spoke-andfelly socket; Fig. 5, a central section of the same in a plane at right angles to the section in FigA.; Fig. 6, alongitudinal section, as in Fig. 1, but showing an ordinary Wooden hub-box inserted in the hub 3 Fig. 7, a crosssection of the same in a plane indicated by the line a: x, Fig. 6.

Like letters designate corresponding parts in all of the figures.

My invention consists in an improved malleable castiron hub, very light and ot' good form and appearance, particularlyT adapted to light buggies and other vehicles, being formed to receive the ordinary boxing used with Wooden carriage hubs, The spoke mortises thereof are formed with Wedge-shaped partitions between, coming to an edge, or nearly so, toward the center of the hub, and from thence the space being all occupied by the mortisecavities except a thin partition around the central axle-bore. By this construction the spoke-tenons are ofthe full width of the spokes, are less tapering, so that they iit more securely in the mortises, and they touch each other and mutually sustain themselves within the Wedgeshaped partitions Withoutproducin g any strain on the hub; but this construction ofthe spokemortises in the hub I do not claim of itself.

In Figs. l and 3 it is seen that the mallea ble-iron hub A is cast inV one piece, thin and light, and the axle-bore is formed to receive the ordinary wooden hub boxing D, Figs. 6 and 7, Without requiring any iitting or special con struction to admitand secure them in place, therebeing simply notches c c cast in the bore toreceive the feathers of the boxes and prevent their turning in the hub.

The box D, if desired, may be kept from slipping endwise by a stop, h, Fig. 6, or any convenient means.

In Fig. 2 is most clearly shown the spokemortises b b, occupying all the circumference of the hub except the Wedge-shaped partitions c c between them, which partitions come to an edge, or nearly so, at theirinner eXtremities. TheyT thus allow the spokes B B to fit between, with their full width at their outer parts, and to touch each other within the partitions, and thereby to bear andl brace against one another. tapering, there is little or no tendency in the spokes to draw or Work out of 'the mortises, nor to push in beyond the limit desired.

I make a spoke-aiid-fellysocket, C, as shown in Figs. 4 and 5. The socket f, that receives the tenon of the spoke, is made uniform in size or diameter, and not tapering, and at the outer edge, g, it is beveled inward, as shown, to receive the spoke-tenon, obliquely shouldered to lit the same, as indicated in Fig. 5;

The advantages of this form of the socket are that the tenons t more securely Without any fastening device and Without any tendency to draW out, and the inner bevel to the edge makes a good joint without special care to fit the same, and yet the joint does not show, even when imperfectly fitted, and there is no liability of the paint or varnish cracking at and showing the joint. ,This socket also may be made of malleable castiron.

What I claim as my invention, and desire to secure by Letters Patent, is-

A carriage-wheel hub cast in a single piece of malleable iron, formed to surround a spokeniortise cavity, with Wedge-shaped spoke-separating partitions c c in the outer circumference thereof, and formed with notches a c, and shaped and adapted to receive the ordinary Wooden hub -boxes, substantially as herein specified. y

The above specification of said invention signed and witnessed at Hurd, Pennsylvania, this 24th day of March, A. D. 1879.
