METALLIC VEHICLE-WHEEL.

Specification of Letters Eatent. P t t d Ju 1 19 2,

Application filed December 12, 1910. Serial No. 596,841.

the following description of my said inven-. tlon, taken in connection wlth the accompanying sheets of drawings, forms a full, clear,

' and exact specification, which will enable others skilled in the art to which it appertains to make and use the same.

This invention has general reference to metallic vehicle wheels; and it consists, es-

sentially, in the novel and peculiar combination of parts and details of construction, as hereinafter first fully set forth and described, and then pointed out in the claims.

The object of this invention is the production of a strong, durable, serviceable, cheap, and effective vehicle wheel formed entirely of metal in the process of casting,

said vehicle wheel being adapted for use in all kinds of vehicles, such as carriages, wagons, automobiles, gun carriages, &c., and constructed for operation with, or without resilient tires. To accomplish these desired results, I construct a metallicvehiole wheel,

as shown in the preferred embodiment of my invention, in the accompanying drawings already referred to, in which- Figure l is a front elevation of the said vehicle wheel. Fig. 2 is a sectional view of the same on line w :c of Fig. 1, part of the figure being shown in elevation. Fig. 3 is a similar view of the -central portion of the same, the figure being drawn on an increased, scale. Fig. is a sectional view of one of the spokes, on line 2 2 of Fig. 1.

Like parts are designated by corresponding symbols of reference in all the figures.

This wheel, in its preferred form, is produced entirely in. a single piece of casting, preferably of a uniform, lowcarbon steel. It comprises a central hub 12, which has a tapering bore 13, and which is externally screw-threaded atboth ends at 1.4, 15, the former screw-thread being adapted to re .ceive the usual oil cap 16, and the latter screw-thread being designed to receive the closing cap 17. In the bore of the hub 12 there is located a tapering sleeve 18, made from a high-carbon steel suitably hardened and ground, there being in the bore of this sleeve two oppositely-taperingrace-ways 1t), 19 constructed to receive roller bearings 20, 20, of approved construction.

21 designates the axle, and 22, the spindle thereof, which latter part is located in the bore of the sleeve 18, as illustrated in Fig. 3.

23 designates the fixed rim or tread of the wheel. It is of substantially semicircular transverse section, and it has upon its outer periphery a central, outwardly-projecting rib 24, and leading therefrom, and transversely to the periphery of said rim, a series of equally-spaced mud-lugs 25, the mudlugs on one'side of said central annular rib 24 being staggered with reference ,to those on the opposite side thereof. This rim 23 is connected. to the hub 12 by twoseries of.

curved spokes 26, 27, the curvature being somewhat less than a semi-circle, the series of spokes26 starting from one side of the median line of the hub, and the series 27 starting from the other side thereof, both series of spokes being convergingly arranged so as to gradually merge one into the other and finally terminating in the inner surface .of the rim, in the same plane, These spokes are curved in opposite directions, the series 26 all curving in the same direction and the series 27 all curving'in the opposite direction. These spokes being angular in relation to the plane of the wheel, it follows that while the two series of spokes are just in contact with each' other at the hub or slightly overlapping each other, as indi:

cated in Fig. 2, they gradually merge one into the other at the intersecting points thus forming an integral bond to the spokes at each intersecting point, so that a vehicle wheel constructed'in the manner described is extremely strong, yet comparatively light, while at the same time the wheel can beproduced at a very reasonable'cost. At the angles formed by the intersecting spokes where they cross er'ch other nearest to the hub,

there are formed punctured lugs 28, to which may be secured the brakerim 29, Figs. 1 and 2, and at the second intersection of said spokes there are formed similar lugs 30,

adapted to receive the usual driving sprocket wheel 31.

In cases where the wheelie fastened to the axle and the driving power applied to the axle, I dispense with the roller bearing in the hub and substitute for the sleeve 18 a sleeve having a 'boresufiicient'ly small in diameter to lit the spindle 22, by a close fit,

the wheel being secured to the spindle in,

any approved and eiiicient manner. To retain the sleeve in the hub, I provide a number of fastening screws 32, Fig. 3, or other suitable means to accomplish the desired object.

I now desire to call attention to the fact that the entire wheel is readily removed from its axle by releasing the screws 32 in the wheel-hub, leaving the sleeve 18, with its roller bearings intact upon the axlespindle. This result is of considerable importance in cases where repairs to the tire become necessary, for the reason that repairs to pneumatic or resilient solid. tires,

ing one into the other at their intersecting points, the spokes being curved and the curvatures being in opposite directions as heretofore state the whole being an integral body, possesses the quality of being extremely strong, light, yet flexible, is not liable to rupture caused by jars and jolts over rough roads and pavements, nor by the ever-varying expansion and contraction due to the influence of heat, thereby especially fitting this wheel for extensive travel in any country, over every class of roads and at all -"plane, said spokes intersecting-one another,

seasons of the year, with the positive assurance that accidents and delays will not be caused by a failure of the wheels. It will be further observed that this all-metal wheel. is also well adapted to receive the extremely wide fixed rims that are necessary where a' vehicle is used upon sandy or wet soil, a fact that will be readily understood by persons skilled in the art to which this invention appertains.

set of said curved spokesbeing likewise approximately tangent to said hub but projecting in the opposite direction therefrom, said spokes intersecting one another at a multiplicity of points between the hub and the tread and gradually merging into one another, the wheel being formed in one in tegral piece of casting.

2. A vehicle wheel formed integrally in I one piece ofcast metal, comprising, a figted rim or tread, a double series of curved spokes, and a central hub,-one series of-said spokes being curved in one direction, and the other series of spokes being curved in the opposite direction, one set of said spokes radiating from said hub on one side of the center thereof, the other set of said spokes radiating from the, said hub on the other side of the center thereof, said spokes gradually merging into one another and finally all terminating at the tread in the same at a plurality of points between the hub and the ,tread.

In testimony that I claim the foregoing as my invention, I have hereunto set my hand 1n the presence of two subscribing wltnesses.
