CIT

N f Annan @ativan Lyon, in the French VRepublic, have invent-iy ed certain nenT and useful improvements in Elastic lWheels, ci" which the following is a specification.

This invention relates to elastic Wheels and consists oi novel construction et indeu pendent diametric spokes, surrounding a sleeve adapted. to move relatively to the telly into any position. in the plane ot rotation, said telly being connected to the axle in such a manner to move same or be moved thereby mechanically.

An embodiment ot the invention is shown in the annexed drawing as applied to vehicle Wheels in which the elasticity is obtained by springs which react on the spokes.

Figure 1 is a vertical sectional elevation on the line 1-1 ot' Fig. 2, and Fig. 2 is a vertical section on the line 2 2 ot' Fig. 1.

A sleeve A, loosely mounted on the aide B in the event of same being` driven by means of a chain and pinions C, or driven by the axle direct when the latter acts as driving member carries rigidly flied thereto radial bars D, which slide in recesses D1 formed in the walls of extensions il, ,lll of the diametric spokes. The latter are formed perpendicularly to said ,recesses as tubes il, which are caused to successively engage spring pressed tubes G during the ruiming oi' the wheel. The said tubes G arranged at distances apart corresponding to the spoke tubes F, transmit the load on the hub or axle to a series of conical helical springs ll the preferred section of which in practice is rectangular. Said springs are inclosed in the conical outer ends of tubes l, which rigidly connect the central drum or hub J to the telly K. The aforesaid sleeve A carries at each end, a plate L adapted to follow all the positions of the hub in the plane ol rotation of the Wheel., but guided laterally by bearing against a ring M integral wth the central drum-J. -A cover N is provided to protect the interior from dust.

Only one ot' the plates -L is rovidedivith a flexible connection of suitab e material at the frame side ot' the Wheel to permit uni versal movement oi the sleeve Without affecting the tightness necessary 'for lubrication. The spokes are separated trom the tubes for the purpose of securing indcpcnd' ent movement and to prevent the greater pressure ot one spring overcoming the lesser 'he tters Patent.

pressure lof a spring diametrically opppsite thereto. F rom the above construction it results, that each shock to which the tellyl is subjected either due to the road or by di'tlerent conditions of ruiming, is transmitted to thesleeve A by means ot the spokes, after having been absorbed to a very large extent by the springs reactingon the ends of the spokes. In order to produce this result, each spoke must be capable of independent movement without being in any Way counter-- acted. by the movements of any or all of the remaining spokes. Thus, assuming a diametrical spoke to bein a position parallel to the road lt will be seen that owing to the central enlargement E the guidance of'wliich is perpendicular to the axis of the spoke, the ring J is permitted to move in any direction in the plane otrotation of the wheel even with an inclined displacement, and this movenient will in no case be counteracted by the horizontal spoke, which at this moment becomes independent.

Since the Wheel consists et an assemblage of rigid mechanical parts, no transverse deiicction can take place, andthe hub is guided over a large diameter by the plates L in rigid connection with the sleeve, and bearing Yon the rings M.

Vtvhat l claim as my invention and desire to secure by Letters Patent ot the United States is 1. nn elastic Wheel comprising in combination a rigid telly, a hub independent thereoli, and capable ot movement relatively thereto in the plane ol rotation, a series of dia metric spokes having central portions in sliding engagement with said hub, cushioning means interposed between the enter ends of each spoke and the inner surface oi' the lclly, a central drum and rigid connections between the latter and the telly substantially as described.

2. An elastic Wheel comprising a rigid telly, a hub independent thereof, and capable of movement relatively thereto in the plane ot rotation of the Wheel, a series oi radial vbars rigidly mounted on said hub, a series ot diametric spokes having enlarged central portions, provided with apertures adapted to have sliding engagement with said bars, a spring interposed between thc outer ends of each spoke yand the inner surface oi the "telly, a central drum and rigid connections inclosing portions of the spokes, between said drum and the telly substantially as described.
