DlSTRlOT OF COlJUMBliA VEHlCLEflNHEELt Specification of Reissued Letters Intent.

Original No. 792.89 dated June-20, 190i. Appiimtiuu fa To all whom it may concern.-

Be it known that I, LOUIS A. HILL, it citizen of the United States, residing at VVeshington, in the District of Columbia, have invented certain new and useful lmorovements in Vehicle- Wheels, of which the followin is a specification.

iEly invention relates to an improved ve hiole-wheel; and it consists in the parts eonstructions, and combinations herein described and claims The objects of .ny invention. are to prov tie & cushioning-rim for vehicle-wheels Wh will combine great strength and diiire-hm' with quickness oiirecovery and which. is pro-- vided with a resilient tire constructed to minimize wear on firm weilkept roads, and to present an increased width of tread on soft and sandy roads to provide for the in-- creased traction required thereon.

In the accompanying drawings forming a, part of this application, Figure 1 is a detail perspective view illustrating a preferred embodiment of my invention. Fig. 12 is a iietail persr-ective view, on an enlarged scale clearly showing the attachmentof a threaded head to one of the side springs. Fig. 3 is :i. sectional View on the line 3--3 of Fig 2. Fig. 4 is a detail longitudinal SQCiLlOIiitl View through the wheel-rims, il ustrating the construction =1: arrangement of the medial series of s Fig. 5 is in end view of the per Fig. 6 is e'detail inner tion of the outer wheel-rim, em, detail view illustrating the constructimi t.- the flexible shields or closures Referring to the drawings, '1. indicates the inner rim of a vehicle-wheel, which is so i the I cured upon any desired type of huh h; usual form of spokes. A periplmml plat 2, of rigid material, is secured to the rim 1. and

provided with oil'set flanges 3, to which sire secured the inner ends of the two side nuilfifl of springs t and 5.

An outer wheel-rim 6 is shown c4.unprising a steel ring provided with ev central lo tudinal ollsct or corrugation 7 ext-en; from its outer periphery, for stillening said rim and engaging a correspiinnling recess in the inner periphery of a resilient tire is.

The tire 8 has an inner peri'pl'icry coni'orxm ing to the ou r eriphery o!" the ripl 6 and i provided with an angular tread, (shown orined by two inters mg arcs or ot' suitable curved surtaces 9.)

I I uts 21 threaded on the several screws 19,

are provided with oppositely-disposed eyes 22, which constitute securing means for the inner ends of a medial series of springs 23. A similar series of screws 24 are shown extending through countersunk unthreaded apertures arranged in the outer rim 6*lnapproximately radial lines with the sp] mgs 4 of the remaining side series of springs each screw carrying. a nut 25, provided w ith oppositely-disposed eyes 26, which constitute securing means for the outer ends of the medial series of-springs 22. The springs 23 of the medial series are provided with hooks or eyes 27 at each end for engaging the eyes 22 and 26 of the respective nuts 21 and 25, the adjacent springs of the medial series being oppositely inclined longitudinally along the wheel-rim, thus comprising two oppositely-inclined sets of alternate springs, as clearly shown in Fig. 4. In this construction the screws 19 are locked against turning, and

each screw 24 provides a convenient meansfor adjusting the tension of the two oppositely-inclined springs 22, secured thereto,-

thus furnishinga common means for ad'usting the tension of the two oppositely inclined series of medial springs and insuring the maintenance of an equal tension in the said two series.

Two flexible shields or closures 18, of suitable material such as canvas or rubber, are shown extending between the rim-plates 3 and 6 for protecting the several series of s rings from dirt and injury. As shown in Iigs. 5 and 7 the shields 18 are clamped between the rim 6 and tire 8' and extend over the flanges 3, each shield being provided with elongated eyelets 28 adjacent one edge for receiving the links 12 and'with eyelets 29 adj acent its other edge to receive the screws 16.

Wheels consisting of a hub, an inner plate supported by the hub and an outer plate connected by resilient means to the inner plate, are acted on by several forces when in use tending to shift one of these plates relative to the other. One of these forces as the weight on the hub tending to force the center of the inner plate below that of the outer plate. A second force acting tan entially on the outer )late tends to move the outer plate around t e inner plate and as said force acts at one point, i. 0., where the outer plate is in contact with the road, the outer plate will be shifted out of center with the Inner late. A third force operates when the veliicle is moving in the arc of circle, to change the relative position of the plates, laterally.

It is haracteristic of my nnprovement that the resilient means connecting the inner and outer plates are so constructed and combined as to operate to resist laterally and peripherally displacement at and adjacent to the points where the displacing forces act. Re-

sistanee to displacement due to the weight on the hub, is presented by practically all of the springs.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is v 1. In a vehicle-wheel, the combination of a cushioning-rim comprising an inner plate, an outer plate, two series of springs oppositely inc ined transversely between said plates, and ainedial series of springs consisting of two sets of alternate springs oppositely inclined longitudinally between said plates, substantially as descnbedl 2.
