IMPQVEMENT IN WHEEL-HUBS.

1 Thechedulereferred to :in these Letters YPateutam making part. of the same.

To all 'whom 'tmay concern:

Be it known .that `I, CHARLES?. WHITMAN, of Ohax-lement, in the conntyot' Franklin and Stateof Massachusetts,` have invented certain f Improvements in .VVheel-Hubs, of which the following is a specifical tion, reference being 4 had to the accompanying drawings..v s

My invention relates to hubs for spoke-wheels,'and arrangement, and

`Figure 1 is a longitudinalcross-section'on the line" xxot'figZ; i

Figure 2 is .an end view with cap removed; Figures 3 and `4A are end views of the caps; and Fignre'5 is an edge or side view of thespoke-re- In constructing 1n y hub `make a wooden hub, A, of any suitable size and form, but preferably o f the shape shown in fg.\1, andscrew it upon an axle-box,

. B, provided'o'n its exterior with a thrcadfor that purpose, j v The relative length of 'the wood hub and the axlebox is such 'as to allow the ends of the box to project a short distance beyond the ends Vof the hub, as shown in the saine figure.v

Upon this wood hub A Isin-ink acast Inet-allie spoke-receiver, F, consisting. of a ring, (t, with a series of radial projections b arranged so as to be equidistant from each other, and form soeketc for spokes H, and also with openings at the bottom ofthe sockets, to allow the tenonsot'- `the spokes to enter a mortise `in` the wood hub, as shown in gs. 1, 2, and

The ring a of the spoke-receiver is made so as to extend la short distance 'on each side of' theradial projections b, and is provided on its outer surface with `a `screw-thread, as shown in the same figure. 0n each end of the axle-box Ivscrew a cap, G, provided `on the inner surfaceof its outer end with a screw-thread corlgcsponding `withzthat on the axle-box Byand on the inner surface of its` inner end with `a thread corrosponding'with that on the ring a. of. the spoke-receiver, as clearly shown in igfl, the caps beingso constructed that, when in position, their inner face will bear against the projections b and completely hide them, and theironter ends be finsh with the ends'.

of the axle-box or not, as desired.

` The form, outwardly, of the caps` may be shaped to suit the fancy, the one on the outer end of the hub being shaped as shown in iig. 3, and one on the inner end las shown in'fig. 4.

The spokes H are then driven into the sockets c, their ends being suitably shaped yfor that purpose,fand provided with a tenen to entera mortise in the wood hub, as sho'wnin igsfl and 2, and to shoulder upon it. l

In ahub constructed in this way it will be seen that the parts of which it is composed t compactly together, andsiionld any of these parts become injured or broken, t can be replaced by another, and the whole her as strong asit was in the iirst instance.

It isobvious thatv iny spoke-receiver may be used onwcoden hubs without Vthe caps, if desired, and that by means' of it a strong anddurable' connection between the hubs and spokes can b'e made.'

Whenthe caps are on it will be seen that their inner faces form flanges that bear against the sides of the spokes, and aid materially in holding thenisecnrely in position.

Having thus described my invention,

l. A hub 'for carriages or wagons, consistingof the wooden body A, having the box or tube B inserted therein, and protruding at each end, with the caps G screwed thereon, substantially as described.

- 2. The combination of the body A, box lB, spokereceiver Rand caps G, when constructed and arranged substantially as herein described..

CHARLES I. WHITMAN.
