WHEEL FOR ROAD-VEHICLES.

SPECIFICATION forming part of Letters Patent N o. 718,275, dated January 13, 1903. Application filed March 19, 1902. Serial No. 98,879. (No model.)

To all whom, t nur/y concern:

Be it known that I, GLENOAIRN STUART OGILVIE, a citizen of England, residing at The Lodge, Woodbridge, in the county of Suffolk, England, haveinvented certain new and useful Improvements in NVheels for Road'- Vehicles, (for which I have applied for a patent in Great Britain, dated October 3l, 1901, No. 21,957,) of which the following is a speci# ication.

This invention relates tothe construction of wheels for road-vehicles in such a manner as to obtain a certain degree of resilience in both radial and circumferential directions without the danger of punctures, such as happen to pneumatic tires and render them inefficient. For this purpose I construct the wheel as I shall describe, referring to the accompanying drawings.

Figure lis a longitudinal section of part of the circumference of a wheel according to my invention. Fig. 2 is a corresponding section showing a modification. Figs. 3, 4, and 5 are transverse sections, respectively, on the lines 3 3, 44, and 5 5 of Fig. l.

a is the felly, which may be of wood or other suitable material, preferably surrounded by a band b of iron or steel, which preferably has a groove in theform of a circular arc adapted to receive a number of elastic balls distributed all around the circumference.

d is an outer ring of iron or steel, to which are attached, as will hereinafter be described, segments forming rings e of thin sheet metal lined with wood rings f, which can slide radially along the sides of the felly ot. The outer ring d is surrounded by a band g of caoutchouc or other elastic material and preferably has inner linings h of Wood, forming a circular groove to approximately it the balls. The ring might have the interior grooved form without linings. Through the of'd. Each piece m has a rib p projecting inward and provided with an elastic buler q. The bolt-heads k and the projections p constitute stops, against which the balls abut, and form an elastic driving medium between the felly within and .ring d without. The stops la and p may be arranged, as shown in 2, so that only a single ball is-interposed between kfand p. In this case the two stops p project inward from onesegmental piece attached to the iianges of the ring d by two screws n.

In putting the wheel together the segmental pieces fm, having the projection p, are put close to the felly, so that the outer ring d can be putin position outside of them. They are then brought up to the ring and secured by the screws fn. The rings e, of sheet metal, lined with wood, are made in four segments and are screwed to the cheeks of the segmental pieces 'm after these have been fixed to the ring CZ.

Although I have shown balls interposed between the felly and the outer ring, obviously elastic bodies of other forms might be employed.

`I am aware that it has been proposed to construct a wheel with an outer ring or tire separate from the felly and withballs'or other elastic bodies interposed between them, and

I therefore make no general claim to such construction; but

What I claim is- In a wheel having a continuous outer ring or tire separate from the felly and movable cireurnferentially thereon, stops such as lo projecting from the felly and projections such as p from the outer ring in combination with elastic balls or their equivalents interposed between them to constitute an elastic driving medium between the felly and the outer ring, Substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

G. STUART OGILVIE. Witnesses:

GERALD L. SMITH, EDWARD GARDNER.
