Application file-i July 9,

To all @071.0211 t may concern:

Be it known that l, JOHN MTLLAR. a citi Zen of the United `States, and a resident ot rirlington, in the county ot Hudson and State ot New Jersey, have invented certain new and useful lmprovements in Road lVheels, et which the following is a specification.

rThis invention relates to tires for automobiles, or the like; and has tor its main object and feature the production of a simple, efficient and inexpensive punctureless tire.

ln the accompanying drawings the invention is embodied in a concrete and preferred form in which- Fig. 1 is a transverse vertical sectional view of a tire embodying the invention:

Fig. 2 is a side elevation partly broken away and in section:

Fig. 3 is a detail sectional view on the plane of line 3 3 of Fig. 1:

Fig. 4 is a detail sectional view of one ot the intermediate thrust members.

1 indicates a cushion, preferably a pneumatic cushion, located remote from tread 2 and which may be adjacent to the hub of the wheel; or, as shown in the present instance, between cheeks 3 of a disc wheel. IThese cheeks are bolted together in any suitable manner as by bolts 4 and are provided with a tilling member 5 of wood or other material that also acts as an abutment member for the cushion. rlhe conformation ot cheeks 3 is of such character as to afford an enlarged space 6 in which the pneumatic cushion is located. This pneumatic cushion may be, and in the present instance is, a tube with both ends closed as at 7 and in butting engagement and may be introduced into the space 6 through opening 8 conveniently provided with a removable cover 9. Valve 10 in the pneumatic cushion extends between the aforesaid cheeks 3 and up through an opening in member 5 and may be rendered accessible by means ot an opening 11 in one of said cheeks provided with an adjustable cover 12.

13 indicates a plurality of radially movable inner segmental members, the number of which may vary but here consisting of tour such members. 14 indicates a plurality of radially movable outer segmental members, there being in the present instance twelve such members. The inner and outer segmental members are connected by means 1921. Serial No. 423,405.

around to bring the elongated parts of theheads under the 'lianges ot the sockets* Outer segments 14 are also provided with soclrets 21 formed by ianges in adjacent ends of two adjoining sections 14; each section 14 extending from substantially the center of one head 19 to the center of the neat adjacent head 19. Suitable means are provided for guiding the thrust members. ln the present instance these means take the following form: 22 indicate guides through which members 17 of the extensible thrust members pass, said guide members being provided with projections 23, that pass through cheeks 3, the outer ends of which are threaded to receive nuts 24 to thereby hold the guide members stationary with respect to said cheeks, and to bolt said cheeks together at their outer edges. To properly guide tread 2, annular guide members 25 are provided which are conveniently clamped between cheeks 3 and nuts 24. The inner ends of guides 22 are provided with cups 2G containing a washer 27 bearing against sockets 2O of inner segmental member 13. To prevent ingress of dust, cheeks 3 are bent inwardly at their outermost edges 28 to form a shield. Tread 2 is continuous and the outer segmental members 14 may be secured to it in any suitable manner as by being imbedded in said tread, as shown.

It will now be understood that during the revolution of the wheel that portion of the tread which is against the ground will cause that segment 14 which is adjacent thereto to cause a thrust member 16--17 to move inwardly through guide 22 and will transmit the thrust to inner segmental member 13. Because the intermediate thrust members are extensible, the thrust produced by one of these members will cause segmental member 13 to pull only inner part 16 of the next adjacent thrust member with it, and said segmental member 13 will slide against the inner walls of cheeks 3 and thus transmit the thrust to cushion l. The tread in producing this action will slide in guides 25. I claim- 4 A road wheel comprising: cheeks composing the body of the wheel, a cushion located between said cheeks and remote from the periphery of the Wheel, an abutment member against which the cushion acts, a plurality of guides located between the Cheeks, extensions on said guides passing through the cheeks and b olted thereto, annular guide members carried by the cheeks, a plurality of outer segmental members having sockets memos on their inner faces, a tread carried by the 15 outer segmental members between the annular guides, a plurality of inner segmental members, bearing against the cushionbetween the cheeks, having sockets, and a plurality of extensible thrust members passing 20 Hudson and State of New Jersey, this lst 25 day of July 1921.

JOHN MILLAR.
