WHEEL FOR VEHICLES.

SfPECIFICATION formingpart of Letters Patent No. 674,720, dated May 21, 1901. Application filed March 15, 1901. Serial No- 51, 293. (No model.)

To all whom it may concern:

Beit known that LHARVEY JAMES WRIGHT, a subject of the King of England, and a resident of Cape Town, Cape Colony, have invented certain new and useful Improvements in l/Vheels for Vehicles, of which the following is a specification.

As the title of my invention indicates, it has reference to improvements in wheels for vehicles.

My invention will be more easily understood by reference to the accompanying drawings.

Figure 1 is an elevation of the wheel. Fig. 2 is a sectional View of the wheel in its vertical position and shows also a sectional elevation of the hub and its attachments. Fig. 3 is a plan of the cylinder with a fixed disk or plate and forms one part of the hub. Fig. 4 is a plan of the disk or plate which forms the other part of the hub. Fig. 5 is a section of triangular iron hereinafter referred to.

Referring to Figs. 1 and 2, A is the rim of the wheel and is made of T-iron. Aa is the flange of the T. B is the tire. 0 represents the spokes, placed in two rows, one on either side of the hub and converging toward the rim, where they are received in sockets D. Ea is the cylinder. H is a disk or plate and is bored to become a sliding fit on the cylinder. GH represents projections to give side support to the spokes. K is the hole for the bearing. J represents the bolts hereinafter described.

Referring to Fig. 2, (see reference to Fig. 1 from A to D,) E is the disk or plate fixed to the cylinder. Ea is the cylinder. F represents the sockets in which the ends of the spokes are placed. 6} represents projections from E to give side support to the spokes. E and Ea form a sectional elevation of Fig. 3. H (as described under Fig. 1) has sockets FH and projections GH exactly similar to E. H is a sectional elevation of Fig. 4. J represents the bolts (three in number) of the variety known as hook-bolts and pass through the hub from plate to plate parallel to the cylinder. They are partly embedded in the cylinder, and the portions passing between plate H and the cylinder are also-partly embedded in plate H. J a represents the nuts and are of the variety generally known as nipples. K is the hole for the bearing.

Referring to Fig. 3, E is the plate, showing the sockets F to receive the spokes and the projections G for side support. Ea is the cylinder. K is the hole for the bearing. Jc rep-- resents the beds for the bolts. Jae represents the holes for the nipples.

Referring to Fig. i, H is the plate, showing the sockets FH and the projections Gl-I exactlysimilar to E, Fig. 3. L is the hole through which the cylinder passes. JH represents the beds for the bolts.

Referring to Fig. 5, this is a section of triangle iron and is used to form a rim for the wheel should it be preferred to T-iron. D represents the sockets to receive the spokes.

To further illustrate the principle of my invention and the way it is put into operation, reference is made to the hub. This consists of a cylinder of metal through which the longitudinal hole K, Figs. 1, 2, and 3, passes to form the bearing. At one end of the cylinder is a plate affixed and at the other end a plate detached. (See E and H, Figs. 1, 2, 3, and 4.) In the plates are sockets to receive the ends of the spokes. Bolts pass through from one plate to the other, by means of which the plate H can be moved backward or forward on the cylinder. The object of this is to tighten the wheel (which through wear and tear has become loose) without having to resort to the old method of shortening the tire. This is effected by reducing the distance between the two rows of spokes at the hub by means of the bolts drawing the sliding plate H, which carries one row of spokes, closer to the fixed plate E, which carries the other 'row. As the spokes then require more diametrical room, they are forced firmly into the sockets both at the rim and the hub. The spokes of the wheel are made of wood and cannot be limited as to number or shape. The rim of the Wheel is made of iron in the form of what is known as T-iron. On the flange of the T Aa, Figs. 1 and 2, which is placed on the inside of the rim, and from alternate sides sockets are punched to receive the ends of the spokes, as shown at D, Figs. 1 and 2. I do not limit myself to the particular form of T-iron; but I claim also the use of iron in a triangular shape, as shown in Fig. 5, in which sockets D are wrought, cut, or cast to receive the ends of the spokes.

I do notclaim for the Wheel any special bearing or method of attachment to the vehicle. It can be adapted to any hearing or method of attachment in common use. I claim that my invention is novel and has great advantages over wheels at present in use, because that by reason of the two rows of spokes it has immeasurably greater strength, that being stronger it can be made relatively lighter and is consequently easier of draft, and that when the wheel has become loose from shrinkage of the spokes and general Wear and tear it can be tightened in a few minutes by screwing up the bolts, as hereinbefore explained, thus obviating the necessity of cutting or shortening the tire. This can be done with the aid of a spanner at any and all times. Should the Wood swell through soakage of Water and the pressure become too great it can be immediately relieved by unscrewing the bolts. Should a spoke break it can be replaced at once by the most inexperienced hand. The outward pressure of the spokes into the rim from either side prevents warping of the rim. The load is distributed through a larger number of spokes at any given point in a revolution than is the case with Wheels at present in use. Skidding or side strain on uneven ground takes little As the spokes are not held or no efiect on it.

other than by pressure from either end, it is impossible for them to receive any cross strain. The Wheel can be taken apart and packed for transport or for storage and requires neither a practical hand nor special appliances for resetting the same. The iron rim with flanges does away with the Wooden rim or fellies of ordinary Wheels and takes upon itself the duty of holding the wheel together, which is performed by the tire of wheels at present in use. As the tire is used only to present a Wearing-surface, it can be made much lighter and can be used until it is completely worn through.

I claim A vehicle-wheel comprising a metallic rim having a plurality of spoke-sockets, a cylindricalhul) or sleeve, a collar movably mounted on one end of the sleeve and having a plurality of spoke-sockets, a second collar on the other end of said sleeveand abutting against a shoulder thereon, spokes having their outer ends seated in the sockets in the rim' and their inner ends in the sockets in said collar, and bolts for drawing said collars toward each other to tighten the spokes, substantially as described.

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

HARVEY JAMES WRIGHT.
