ANTI-LFRICTION WHEEL.

SPECIFICATION forming part of Letters Patent No. 427,301, dated May 6, 1890.

Application filed October 3, 1889.

To all whom, it may concern:

Be it known that 1, CHARLES G. DEMING, a citizen of the United States, residing at Voodstock, in the county of Ulster and State of New York, have invented certain new and useful Improvements in Frictionless lVheels; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to wheels which are constructed to avoid friction as far as practicable; and it consists in certain improvements in the-construction of such wheels, as herein after described and claimed.

In the accompanying drawings, Figure 1 represents a side view of a wheel provided with my improvements. Fig. 2 is a section of the same, taken on line a: a: of Fig. 1. Figs. 3 and 4 show modifications in the construction of the wheel.

A designates a rim which forms the periphery of the wheel, and is provided with an inner flange or rib a.

B indicates a cylindrical axle, which is provided with an exterior flange or rib a',which when the parts are in position is on the same vertical plane with the rib a.

\Vithin the rim A and surrounding the axle B is placed a series of wheels O, which bear against the rim and the axle. Each of the wheels 0 is divided or open from the periphery toward the center, as shown, to admit the endless bands hereinafter mentioned, and also the flanges a a of the rim and axle. The said wheels C may be made in two corresponding parts, as seen in Fig. 2, said parts being secured together by a central bolt 0.

D indicates a series of rollers which are arranged on a-circle and severally placed between two of the Wheels 0. The said rollers are grooved at their peripheries, as seen in Fig. 2, the central parts 6 forming bearings for the rings or hands I) and d, by which the rollers are held in place. These bands extend around through the openings in the wheels 0, the central parts f of said wheels forming bearings for one of them. The inner band b is outside of and against the central bearing f of each wheel 0, and is within Serial No. 325,831. (No model.)

and against the central bearing 6 of each of the grooved rollers D. (See Fig. 1.) The outer band d, being parallel with band b, is outside of the central bearing parts of rollers D and bears against the same. In case great strength is not required a single outer band may be made to answer the purpose. As the main wheel revolves, the wheels O, being in contact with the axle and the outer rim A, are rotated. The inner band b, being outside of and against the central bearings or journals f of the wheels O, is moved in one direction; and the said band I), acting against the central bearings or journals e of the rollers D, imparts to said rollers the same rotary movement which they receive from engagement with the wheels O. The outer band (1, being in contact with the rollers-at 6, serves to keep them in place and moves in a direction opposite to that of the inner band I). The construction is such that the number of revolutions of the rollers D caused by the bands moving on the journals of the rollers Will correspond with the number of revolutions produced by the wheels 0 by contact with the peripheries of said rollers-that is, the two forces acting on rollers D, the one on the journals and the other on the peripheries, will impart to the rollers the same degree of motion. This can be regulated by making the rollers and their journals of proportionate diameters with each other and with the journals of wheels 0.

Every part of the wheel as constructed is independent of the other parts, and if properly constructed lubrication will probably be .may each be secured by a ring I, which fits against the flange g, and bolts r, passed through the rim A, the flange, and the ring.

unnecessary and it will be impossible to over- Packing of rubber or other suitable material may be placed between the rim A and the flanges g to form tight joints.

In Fig. 3 is shown a modification in the construction of the wheel, the grooved wheels 0 being each made in one piece and provided with outside journals 6. The rollers D are also provided with outside journals, and instead of a peripheral groove each roller may be formed with a flange or rib to extend into the openings in wheels 0. Two sets of bands 17 and d are employed with this form of Wheel, one set being applied to each side. The bands have the same bearings on the journals of the wheels Cand the rollers as before described, and may be retained in position by nuts or pivoted washers n on the journals, or by grooves made in the journals to receive the bands. In this form of wheel the axle may be made in two parts, the said two .parts being screwed together. The wheels 0 may be either convex or concave at the periphery,

the other parts which have bearing on said.

wheels being made to correspond.

A further modification of the wheel is shown in Fig. 4, the wheels 0 being constructed in the form of rings and having no central bearing. The rollers D are provided with journals and are held in place by two circular bearing f, the rolls D, with divisional bearings e, and the bands I) d, all combined constructed, and arranged as and for the purpose set forth.

2. The combination, with a wheel, substantially as described, of the centrally-apertured side plates G G, rings I, and bolts 4, said plates being provided with the outward flanges g, as and for the purpose described.

In testimony whereof I have affixed my signature in presence of two witnesses.

CHARLES G. DEMING.
