BULL WHEEL.

Application filed April 11, 1924. 3 Serial No. @5322.

To all whom it may concern:

Be 1t known that we, CLYDE S. VVRIGI-rr and FREDRICK J. SOHWIMMER, citizens of the United States, residing, respectively, at T0- ledo, in the county of Lucas and State of ()hio, have invented new and useful Im- 'iroven'ients in Bull Wheels, of which the following is a specification. 7

Our invention relates to-bull-wheels, and more particularly to the brake=wheel portion thereof. It is the main object of our invention to provide a bull-wheel or the like having its spokes and rim composed of angles while the rim carries a medial fin or plate to which a selected rim-covering may be secured.

Referring to the accompanying drawing, Fig. 1. is an end View of a wheel, constructed according to our invention, the tie-r0d 4 be ing omitted, and Fig. 2, a central vertical section on an enlarged scale, taken on the line IIII of Fig. 1, the shaft, the tie-rod and the lower part of the wheel being broken away. 7

On the drawing, 1 designates the hollow steel shaft of the wheel, the metal gudgeon 2 being driven upon the end of the shaft and secured thereto by the screws 3 which are headed down on the periphery of the gudgeon. In the complete bull-wheel there is a tug-wheel at the end of the shaft which is broken off, where another gudgeon is applied in the same manner as the one described. The screw rod 4 passes axially through the shaft and the gudgeons for tying them into a fixed unit.

The hub 5 of the gudgeon 1s provided with four evenlyspaced peripheral lugs 63.

, Four steel angle-bars, 7, 8, 9, and 10, shown as channels in the present case, are provlded for use as spokes. The pair of channel-bars 7 and 8 are parallel and are attached by. bolts 11to the adjacent faces of the lugs 6, and the pair of channel- bars 9 and 10 are parallel, lie at right angles to the bars 7 and 8, and are attached to the adjacent faces of the lugs 6 by the bolts 12 passed through the adjacent channel-flanges. The bars have their channels facing outwardly. V

In the construction of the rim we provide two annular steel rim rings 13, each preferably L-shaped in cross section and having one flange 15 at right angles to the shaft and having the other flange 16 concentric therewith. The two rings 13 are of equal diam eter and are arranged with their flanges 15 opposing each other and having between them the annular steel plate ringor web 17 which extends beyond the periphery of. the rim flanges 16.

The outer ends of the spokes 7, 8, 9, and 10 have their backs lying against'the outer faces of the flanges 15, the spokes 7 and 8 engaging one flange 15 and the spokes 9 and 10 engaging the other flange l5. Bolts 14 are passed through the flanges 15 and the web 17 to clamp the spokes securely to the rim-rings 13. Rivets18 may be used to secure the plate and rim-rings into a unit. The rim-rings may be divided into segments as shown at the joints 19.

Spacing blocks 20 are placed between the backs of the channel bars at the places where they cross, the blocks being of the same thickness as the plate 17 and the two flanges 15. .Bolts 21 are passed through the said bars and spacing blocks to bind them toi gether.

Circular wooden cant-facings or rim-cow erings 22 are arranged on the rim-flanges 16 in an evident manner, there being an annular group'of cants on each side of the plate or web 17 whose periphery is somewhat within the periphery of the cant-facings. The groups of cants are preferably built up on the rim from individual cant segments in the usual manner of making cant-facings. The two annular groups of cants are secured to the rim and the web by the bolts 28 which pass through them. This web may obviously be made of segments arranged end to end.

We claim 1. In a bull-wheel, a wheel-rim comprising a pair of metal rings in axial alinement and of angular cross-section, one side of each ring forming a rim member concentric with the axis of the wheel, and the other side of each ring projecting toward the said axis. a metal web clamped between the side members last named and projecting outwardly beyond the rim members, cants seated on the rim members, means securing the cants to the web, a shaft, and means securing the shaft to the wheel rim.'

2. In a bull-wheel, a wheel rim comprising a pair of metal rings in axial alinement and of angular cross-section, one side of each ring forming a rim member concentric with the axis of the wheel, and the other side of each ring projecting toward the said axis,

ametal Web clamped between the side'meinbers last named and projecting outwardly beyond the rim members, cants seated on the rim member s, means securing the can ts t0 the Web, a shaft, a gudgeon secured to the end of the shaft and bearing radial lugs spaced ninety degrees apart, two pairs of tangential spokes, themembers of one pair crossing the members of the other pair, and means colmecting the ends of the spokes to the rim and the intermediate portions to said lugs, 31 i 3. In abull-wheel, a Wheel-rim comprisi i g a pair of metal rings in axial alinement and each ring projecting towardt'he said axis. a

metal Web projecting outwardly beyond the rim members and rigidly connected to the said rim and between the edges of the latter, cants seated on the rim members, means securing thecan-ts to the Web, a shaft, and means securing the shaft to the wheel rim. In testimony whereof, We hereunto aflix our signature this 22nd day of March, 1924. CLYDE S. WRIGHT.
