CUSHION-TIRE FOB VEHICLE-WHEELS.
Specification of Letters Patent.
Patented March 2, 1909.
Application filed April 4, 1908. Serial No. 425,200.
To all whom it may concern:
Be it known that I, BENJAMIN F. FRY,- a citizen of the United States, residin at La Crosse, in the county of La Crosse an State of Wisconsin, have invented certain new and useful Im rovements in Cushion-Tires for Vehicleheels; 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, reference being had to the accompanying drawings, and to the letters of reference marked thereon,
which form a part of this specification.
This invention relates to new and useful improvements in cushion tires for vehicle wheels and the object in view is to produce a simple and eflicient device of this character from which may be obtained the same cushioning effect as produced by a pneumatic tire and, atthe same time, a much more durable substitute.
The present invention comprises various details of construction, combinations and ar-- rangements of parts which will be hereinafter fully described and then specifically defined in the appended claims.
I illustrate my invention in the accompanying drawings in which 1 Figure 1 is a side elevation of a portion of a tire, parts being broken away to better illustrate the cushion arrangement therein.
' Fig. 2 is a cross sectional view through one of the spring sections of the tire. Figs. 3 an'd4 are eta1l views of the tension and core s rings, and Fig. 5 is a detail view of one of t e core springs, Fig. 6 is a detail perspective view of one of the concaved plates.
1 having ends Reference now being had to the details of the drawings by letter, A designates the rim of a wheel, it being my purpose to apply my invention to any ordinary rim of a vehicle wheel. Said riin'is provided with a circumferential groove A and has a dished or cencaved circumference as 1s customary w1th B-B desi nate a series of resilient bands bent at angles and adapted to be seated in said circumferential groove.
held frictionall Mounted within each band is a tension spring 0, the ends 0 of which are adapted to be between the ends B of the band B in sai groove, as shown clearly in the cross sectional view of the drawings. A
core spring D is interposed within the tension spring 0 and has its ends fastened together and positioned within the space E in the loop portion. of the spring C. The loop portion C of the tension spring is adapted to bear against the inner circumference of the band B at a position diametrically opposite the ends of the latter, as shown-clearly in the drawings, and adapted to receive the pressure coming thereon and take up vibration. Said springs are fastened in lace by means of the concaved plates H he (1 by means of screws N to the rim and tension regulating bands, designated by letter O, are provided, each of which is convexed upon its outer circumference and flat u on its inner surface, said concaved portions eing adapted to bear against. the concaved loop portions of the s rings, as shown clearly in Fig. 2 of the awings A suitable cover K of tar felt is placed about the series of resilient bands B and afterward a second covering or case L,
In assembling, the ban s arearranged about the circumference of the wheel with their marginal edges adjacent to each other and afterward the coverings placed thereover, thus making a tire which is practically noiseless and so arranged that any one or more of the bands may be replaced without interference with the others. By the provision of a cushion tire for vehicles as shown and described, a much more durable mechanism is afforded than the ordinary neumatic tire and. practically the same cus onin effect.
at I claim to .be new is 1. A cushion tire for vehicles comprising, in combination with a rim havin a circumferential groove, a series of resi ient bands having angled ends engaging said groove, a tension spring havin a I led ends held between the angled en s 0 said band in the groove of the rim, a core spring mounted within said band, a plate engaging said core spring, fastening means extending through said plate and the rim whereby the band and springs may be held in place, and a covering for said bands, as set forth.
2. A cushion tire for vehiclescom rising, in combination with the rim of a w eel, a series of resilient bands, means for holding the same upon the rimofa wheel,'a tension springhaving a convolution thereof adapted tobear friotionally against the inner circumference of said band, a core sprin having a portion thereof bent upon itsef and frictionally engaging a loop portion of the tension spring, means for fastenin the springs and band to the rim of a whee tens1on regulating bands convexed upon their outer circumferences andadapted to engagxe the oonvolutions of said s rings, as set fort 10 In testimony whereof fhereunto affix my signature in the presence of two witnesses.
