VEHICLE-WHEEL.

SPECIFICATION forming part of Letters Patent No. 325,278, dated September 1, 1885.

Application filed October 7, i884. (No model.)

To @ZZ whom it may concern:

Be it known that we, BENJAMIN RUsHMER and GEORGE A. JOYCE, citizens of the United States of America, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Wheels, of which the following is a specification, reference being had therein to the accompanying drawings.

Our invention is an improved wheel, more especially' adapted to barrows or trucks, and embraces the following peculiar features: A disk or web forming a solid part of and perpendicularly projecting from the middle of the metallic hub; also, a counter-pair of corresponding metallic cireular flanges furnished with central or axial holes and suitable nut.- bolts, so as to closely tit over the hub and be tightly clamped against the sides of said disk; also, an equal number of round holes, at equal distances apart, bored jointly into the peripheries of both the disk and flanges, so as to make in each an alternate series of counter half cylinders or sockets of equal depth, in which to step and fasten the butt-s of the metallic spokes; also, said spokes, having their alternate butts thus stepped and clamped on opposite sides of said disk, inclined or staggered inward to an even central line within the circumference of the wheel tire or rim, and having their outer ends or tips furnished each with a screw-thread and jam-nut, by which to screw outward and tighten the spokes against the inside of the tire; and, finally, a metallic tire or rim suitably pierced with holes, in which to ittingly joint the said sliding and radial spoke-tips, all of which and their purposes are hereinafter more fully described,and illustrated by the accompanying drawings, in which the saine letters designate identical parts of our invention in the different figures respectively.

Figure l illustrates a side elevation of our wheel, showing` the butts of alternate spokes in dotted lines, clamped in place by one of apair of said lianges, and the tips of said spokes tightened by the jam-nuts against the inside of said encircling-tire. Fig. 2 illustrates a vertical crosssection of said wheel, showing the clamping of the spoke-butts by said nutbolts between said flanges and the hub-disk on either side, and the inclination or staggerface, and the center hole to fit over its end of the axle-sleeve of the wheel-hub.

The letter A represents said wheel, in which b represents the axle-sleeve of said hub; c, the said hub disk or web d, the said pairs ot' counter-ianges5 e, the sockets of said spokebuts'; f, the said spokes; g, the said wheel-tire; a, the flange-clamping nut-bolts, and .fr the spoke-tightening jam-nuts.

The whole of the wheel A is made of metal, the hub portion, consisting of said disk and axle-sleeve, being of cast-iron and of suitable dimensions and shape, as shown, the flanges, as shown, to be of malleable iron, and the spokes and tire to be of wrought-iron.

The hub disk or web c has both of its vertical faces turned or planed perfectly smooth and true, so as to have the correspondinglymade inner faces of said llanges d ttingly joined and clamped to them by the nut-bolts n, after being ttingly adjusted upon the hubsleeve b, as shown. Said disk, together with said circular Hanges, have suitable holes bored into their joined peripheries at equal distances apart and of equal depth, so as to make in the outer faces of said disk and the inner faces of said llanges an alternate series of corresponding radial half-bellows, which, when clamped together by said nut-bolts n, form the sockets e, which serve to hold the butt-ends of the spokes f, as shown. Said spokes are made of suitable dimensions and shape, and have their butt-ends thus stepped and clamped alternatelyinto the opposite sides of said disk c, as shown, after having their tip ends suitably staggered or inclined, and tted into their respect-ive socket-holes made in the median line of the perimeter of the tireg. Said spokes have their ends below their tips suitably screw-threaded, and are provided with the suitably-made jam-nuts x, which, being ICO previously screwed upon said spokes for a' suitable distance below their tip ends, are

again screwed outward, after said tips and butts of the spokes have been fitted into their respective smooth-bored sockets in the hub and tire, in order to effectively tighten the combined radial projective resistance of said spokes against the centripetal vtendency of said tire.

The useful effects of the above combination are to make a very strong and `light Wheel, withl its parts ready to be easily and quickly tted and adjusted together; also, Whenever any of said parts become loosened or unjointed, to make them readily readj ustable and useful; and, finally, should any of said parts become broken or worn, to make -them readily, conveniently, and economically interchangeable and renewable; therefore,

Vhat We claim as new, and desire to secure by Letters Patent, is-- l. In the Wheel A, herein described, the combination of the axle-sleeve b, having the vertically -intermedial Webdisk c, and the clamping-disk flanges d, provided each with the coradial half-sockets e, and the nut-bolts n, with the rim g, having smooth spoke-sockets, and the spokes f, provided with the jamnuts x, all made and adjusted substantially as and for the purposes herein specified.

2. In the Wheel herein described, the combination of the spokes having jamnuts with the smooth spoke-sockets of the Wheel-rim and the clampsoekets of the Wheel-hub, substantiall y as and for the purposes herein specified.

In testimony whereof we affix our signatures in presence of two Witnesses.

YBENJAMIN RUSHMER.

GEORGE A. JOYCE.
