A TTURNE Y8 UNITED STATES PATENT OFFICE.

WHEEL-TIRE.

Specification of Letters Patent.

Patented Mar. 8, 1921.

Application filed June 20, 1919. Serial No. 305,564.

To all whom it may concern:

Be it known that I, ORSON HOPKINS, a citizen of the United States, and a resident of Argusville, in the county of Schoharie and State of New York have invented a new and Improved Wheel-Tire, of which the follow; ing is a clear, full, and exact description.

My invention relates to wheel tires, my more particular purpose being to provide a device of this character possessing certain mechanical advantages, among them being resilience, reduction in liability to puncture, and prevention of one part of the tire from shifting laterally in relation to another part.

Reference is made to the accompanying drawing forming a part of this specification in which like characters of reference indicate like parts throughout the figures.

Figure 1 is a side view partly in elevation and partly broken away, showing the mechanism of my device.

Fig. 2 is a substantially central vertical iection through the mechanism shown in An annular member 3 of sheet metal engages another annular member 4 also of sheet metal, this last-mentioned member beingbent over at its edges so that the latter overlap the adjacent edges of the member 3 thus forming substantially a hollow ring. Located within this ring which is of sheet metal is a metallic ring 6 of more massive form. This ring carries a number of supporting blocks, one of which is shown at 7. The supporting block is secured to the ring 6 by bolts 8 and is provided with slanting surfaces 10 as indicated more particularly as in Fig. 1. The supporting block 7 is further provided with slanting surfaces 8 shorter than the surfaces 9 and joining the same or rather forming a continuation thereof. Engaging the

slanting sides

9 and 10 of the supporting blocks 7 are rollers 11 carried by swinging brackets 12 and disposed upon opposite sides of the block. The swinging brackets 12 are mounted upon pivot pins 13, the latter being supported upon a bracket 14. This bracket is fitted in position upon a ring 14*, the latter engaging and being concentric to another ring 14 which serves the purpose of a tire frame and may be of any desired thickness. Secured rigidly upon the bracket 14 and disposed from opposite sides of the supporting block 7 are two guidin posts 16 between which the supporting b ock is adapted to brackets 12 by compressing the springs 19 may be'moved away from each other by the play of the supporting block 7. Normally the rollers 11 engage this supporting block at its narrowest part as indicated in Fig. 1. When, however, the supporting block is forced downwardly according to this figure,

the rollers 11 are merely forced farther apart so as to compress the springs 19. Thus, the

ring 6 and all parts connected rigidly therewith are, as a unit, movable relatively to the outer or peripheral portions of the wheel. The guide posts 16 are provided with compartments 21 and housed therein are antifriction balls 22 which engage the adjacent sides of the supporting block 7 and also the corresponding portions of the guide posts 16 that is, at the boundings of the compartments 21. The balls are free to roll up and down and by so doing they relieve the friction otherwise present between the supporting block 7 and the guiding posts 16.

Connected to the ring 14 are

side walls

25, 26, made of sheet metal and provided with inwardly bent flanges 27, 28, which extend toward and into close proximity to the sides of the supporting block 7. Two

guard strips

29, 30 made of rubber are secured in position upon the ring member 4 by

strips

31, 32 of steel. These strips are each of annular form and are held in position by aid of bolts 33. The bottom edges of the

guard strips

29, 30 are held in position by steel strips 35 through which bolts 34 extend.

The strips 31 are concealed, as the guard strips 29 are bent outwardly over them as may be understood from Fig. 2.

The operation of my tire is as follows: The parts being assembled and arranged as above set forth and as shown in the drawing, the rolling of the wheel upon the ground with the weight at the mlddle portion of the wheel gives the latter tendency to go downwardly. Because of this tendency, the spacing block 7 rides downwardly a little between the rollers 11. These rollers because of their side pressure, under tension of the springs 19, tend to resiliently resist the downward thrust or pressure of the supporting blocks 7 Thus, the wheel has considerable resilienc I As indicated in l ig. 4 any springing sidewise upon one art of the rim relatively to the other part as no tendency to dislocate the various parts as the supporting block 7 cannot move laterally on account of the guiding post 16. a

The

rubber guard strips

29, 30 have suflicient resiliency to allow the motions above described to take place, the distortion of the wheel as seen by the eye being negligible or at least no greater than the distortion of ordinary pneumatic tires.

I do not limit myself to the precise construction shown as variations may be made therefrom without departing from the spirit of my invention. v

Having thus described my invention what I claim as new and desire to secure by Letters Patent is as follows:

1. A device of the character described comprising an annular member, a pair of guide posts mounted thereupon and extending radially inward therefrom, each of said guide posts being provided with a recess, an anti-friction ball located in said recess, a supporting block located between said guiding post and engaging the anti-friction ball, said supporting block having inclined sides, anti-friction rollers engaging said inclined sides, brackets carrying said rollers, springs engaging said brackets for forcing same against said inclined sides, and an inner annular member mounted upon said supporting block and movable relative to said first mentioned annular member.

2. A device of the character described comprising an annular tire member, a bracket secured'thereto and provided with an upwardly extending portion, an arm pivotally mounted upon sald bracket, a spring engaging said arm and also engaging said upwardly extending portion of said bracket, a roller carried by said arm,'a supporting block provided with an inclined surface engaging said roller, and an annular member carrying said supporting block and movable relative to said first-mentioned annular member.

3. A device of the character described momprising an inner annular member, an outer annular member, a pair of swinging arms mounted upon said outer annular memher and movable relatively toward each other, rollers carried by said arms, a supporting block carried by said inner annular member and engaging said rollers, and mechanism carried by said outer annular member for pressing resiliently against said swinging arm.

4. A device of the character described comprising a hollow annular member, a rin carried thereby, a supporting block secure to said ring and extending outwardly there- A from, said supporting block being provided with inclined sides, an atmular tire member encircling said hollow annular member, a pair of swinging arms carried by said annular tire member and disposed upon opposite sides of said supporting block, rollers carried by said swinging arms and engaging the inclined sldes of the swinglng block, and means for forcing sald swinging arms toward said supportin block.
