EDWARD SENDELBACH, OF TERRE HAUTE, INDIANA, ASSIGNOR OF ONE- HALF TO CHARLES MINSHALL, OF SAME PLACE.

SPECIFICATION formngpart of Letters Patent No. 673,850, dated May '7, 1901. Application filed September 10, 1900. Serial No. 29,617. No model.)

To cZZ whom 7123 may concern:

Beit known that I, EDWARD SENDELBACH, a citizen of the United States, residing at Terre Haute, in the county of Vigo and State of Indiana, have invented certain new and useful Improvements in Vehicle-Hubs; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form apart of this specifica tion.

LNIy invention relates to huhs; and it consists in a wooden hub provided with metallic shells covering its ends and secured to the hub by an improved fasteniug.

In certain kinds of Vehicles the trade in sists on having a hub which retains the shape of the old woodeu hub, but has its ends covered with metallic shells to prevent checkin g of the Wood, leaving the central portion of the wooden hub exposed where the spokes are driven in, so as to afford a wood cushion at the joint. Heretofore this style of hub has given poor satisfaction, especially in hot climates, for 'the reason that there was no way of permanently holding the shells on the hub. Screws and nails would work loose and come out. Moreover, their heads could not be concealed satisfactorily with paint, but made ob- =vious and objectionable breaks in the smooth surface. Compressing the shell into the hub ;also proved a failure. My invention overcomes these difficulties by aifordiug a secure fastening for the shell which will not work' loose, requires only a single small Opening in the shell, and when completed is entirely concealed. Briefiy stated, I fasten on each of the shells in the following manner; An -annular groove is turned in the external surface of the tapering end of the hub. The .tapering shell has an internal annular rib, smaller than the groove and arranged at such a point on the shell that when the latter is slipped upon the hub the rib passes over the outer edge of the groove and comes to rest concentricwith the groove, when the shell is pressed on tightly` The groove is then filled with molten metal poured through a small hole in the shell. When the metal cools, the rib lies embedded in it, and the shell is firmly locked to the hub. Furthernore, the metal adheres to the inside of the slell and practically forms a large rib engaging with the groove, so that the shell cannot come off even under the Severe-st clinatic conditions.

In the drawings, Figure 1 is a side elevation, partly in longitudinal section, of ahub embodying my invention. Fig. 2 is a View of one end of the hub with the shell removed. Fig. 3 is a cross-section of Fig. 1 ou the line wa).

The hub may have the usual box A, surrounded by the wooden body or hub proper, B, containing nortises b for the spokes C. The wooden portion B has tapering ends, which are covered by the frusto-conical metallic shells D. In the tapering sui-face of each end of the hub is an exte'nal annular groove b', the outer edge of which is naturally of smaller diameter than the inner edge, owing to the fact that it is nade in a tapering or conical Object. Each shell D has an internal ann ular rib (Z,the inside dia meter of which is greater than the diameter of the outer edge of the groove. When the shell is pressed tightly on the hub, the rib passes freely over the groove and stands concentric with it, as clearly shown in Fig. 1. A small hole is bored through the shell into the groove, and,molten metal E is then poured-in through this hole until the groove is full pletely surrounded. This locks the shell firnly to the hub by a concealed fastening, the only visible indication of which is the small sprue e, filling the hole d'. This is easily covered with paint when the hub is finished.

I an aware that it has been proposed to secure'bands to hubs by pouring molten metal into a groove adj acent to one edge of the band or through a hole in the band into a cavity in the hub; but in both cases there is uo internal projection or rib on the band with which the metal in the groove or cavity interlocks, as set forth in the foregoing description of myinvention and expressly mentioned in the following claims.

Having thus describedmy invention, what I claim, and desire to secure by Letters Pat ent, is-- 1. The combinatin with a grooved hub, of

and the rib is coma shell thereon provided with a rb conoentric with said groove, and metal filling said groove and surronnding the rib.

2. The combinaton With ahub having one or more tapering ends provided with an eX- ternal annular groove, of a tapering shell having an internal annular rb adapted to' pass freely over said groove, and metal filiing said groove and surrounding said rib.

3. The conbination With a, hub having ,an

ex-ter'nal groove, of a shell having an internai A EDWARD SENDELBAOH.
