- To all whom it may concern:

Be it known that'I', EDWARD SENDELBAGH, 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 1mprovements in Vehicle-Hubs; and I do hereby declare the followingto 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 bad to the accompanying drawings,

and toletters of reference marked thereon, which form apart of this specification.

This invention relates to vehicle-wheels, and

more especially to the construction of the hub.

Its object is to provide a wheel in which the desirable qualities of the common wooden hub shall be combined with those of a metallic hub. In the old-fashioned wooden hub, such as is still in use for farm-wagons and heavy carts, the spokes are driven" into mortises or sockets in a wooden nave, and thus they have a certain amount of elasticity or cushion,which enables them the better to resist the various strains to which the wheel is subjected. A

neater in appearance. ,It. is also more durable, since the wooden hub is liable to check or crack, thus impairing its efiieieney; but if .the'hub is made entirely of metal the wooden weakness or other fault in their design, .so'

that they have not come into general use. For instance, prior-inventors have proposed to make a hub with awooden center inclosed by cup-shaped flanges on a metal box; but I have found by experiment that such a construction is not commercially practicable, be-

cause when the parts of such a hub are clamped together the wedging action of the ends of the wooden center results in bursting the cup.-

shaped flanges. In. my invention I aim to avoid these difliculties and objections and produce a hub whichhas all the elasticity of the old wooden hub and the smaller dimensions and strength of the metal huh. I use a wooden center, which is substantially the old wooden hub with its endscut 01!, and I provide this with a. metal box-and usemetal clampingplates' to hold it in place on th'e'box; but these plates are arranged so as not to touch-the spokes. Moreover, the meeting surfaces between these plates and the ends of the wooden center vare in planes at right angles with the axis of .the box,so that the clamping effect is wholly at right angles with said surfaces, and therefore there isno tendencyto strain and break the plates.

In the drawings, view showing the several parts of the hub Figure 1 is a perspective separated. Fig. 2 is a longitudinal section of I the hubwith the parts assembled. Fig. sis a similar view ofa modified form of hub.

Fig. 4 is an end view of one of the clampingplates. Fig. 5 is a longitudinal section of a further modification. Fig. 6 is an elevation of one of the clamping-plates used in this modification. v

Figs. 1 and 2showa hub suitable for a farmwagon or a large cart. The axle A is provided with the usual tapering skein'B and nut b. On this skein fits the tapering box 0, which has at or near one end a collar or clampingplate-c, whose outer face is vina plane at right angles with the axis of the box. This collar fits against thein'nerend of the wooden center D, which, as shown in Fig. 1, is in reality a short wooden hub provided with the usual tral longitudinal bore for the box C. The.

ends of this wooden center are fiat and par- I allel, being in planes atright angles with the axis of the box. Metallic bands 1) are shrunk around the ends of the center D' 'as in the ordinary wooden hub, to keep it from checking. These bands do not come in contact with the spokes, as clearly shown in Fig.- 2. The opposite clamping-plate consists of a flange f on asleeve F, resting squarely against the outer end of the center D and fitting metal hub,

- elastic andyet not toolarge, whil 'wooden center D fromfturning clamping-plates in the-box v with'm'yflatcollar andflmge s w more lugs f", which can be dressed ofi with a file, so as to insure'a proper centering of the sleeve on the box. The outer end ofithe box 1 is screw-threaded to receive escrow-threaded point-band'G, by-nieans of which the center. between the collar and the flange f. j Bo ts H are throughthe collar, center, and flange between every two' D is tightly clam or more spokes and resist any tending to break oil the collaror-the ont'er'edg'e'of' the flange; bolts also prevent the insidethe dry and stick on the skein,

' The axle Al has the usual cylindrical skein'ordriven inthe usual manner, either byhand or bymachine; Owing to the ,comparatively short distance between the'ends of the ma tises and the ends'of the-wooden portion, the
