MITSUJ'IRO MOTOKI AND CHUSUKE YAGI, OF TOKYO-EU, JAPAN.
PNEUIVIATIC TIRE.
Application filed November 29, 1919. Serial No. 341,509.
To (ZZZ 10 71 0222, it may concern Be it known that we, MrrsUJmo Moroni and CI-IUSUKE Yaci, citizens of Japan, residing at Ebara tiun, TokyoFu, Japan, have made a certain new and useful Invention in Pneumatic Tires, of which the following is a specification.
Our invention relates to certain improvements in the construction of pneumatic tires for vehicles, as bicycles, automobiles and the like. More specifically the invention consists in providing the tires, or the inner tubes ofpneumati'c tires, with a number of consecutive chambers, or sections, the partition walls of which are provided. with valves for the automatic distribution of air, and the entire construction is designed to form a construction suitable for the inner pneumatic tubes or for pneumatic tires. Among the objects of our invention are:
First. The production of a safety tire in which leakage is confined to any one particular section without affecting the other sections, should a puncture occur in that particular section.
Second. The provision of means whereby, in case of a puncture or in deflating, air may be released quietly and automatically Without bursting the tire.
Other objects will appear hereinafter from the description and claims.
We attain the objects of our invention by the mechanism illustrated in the accompanying drawings, of which-- Fig. 1 represents a side elevation of a tire, or tube, embodying our invention, showing the tube as being divided into compartments, chambers, or sections, all infiated.
Fig. ltl represents an enlarged sectional view showing the joints of separate sections as being provided with the adjusting valves. Incidentally a corrugated form of tubing is herein shown.
Fig. 111 represents a similar view.to Fig. II, but with the automatic deflating valves in operation.
Referring now to the drawings, wherein similar numbers designate similar parts,it will be apparent that the tube, or tire, is separated into compartments, chambers or sections which are represented by the numeral 1. These chambers are placed end to end as shown in Figs. Ill and III. Each section is formed with end plates 2 at both extremities slightly thicker than the tube,
and consisting of the same material as the tube. The end plates are each provided with inwardly projecting nozzles 3 and 4, of conical shape, and the several sections are joinedtogetherby means of joints 5, located within the nozzles 3. In the nozzles 4 are'inserted tubular plugs or valve heads 7, each having a small hole 6 through its side, and the two opposing valve heads are tied together at opposite ends by a loose string 8, of such length that when the tube 1 expands beyond a certain limit, the string connecting the valve heads will gradually dislocate said heads sufficiently to permit air to escape gradually throughthe opening 6, and thereby prevent excessive expansion and bursting'of the adjoining section. Obviously this type of valve may be modified without departing from the scope and spirit of our invention. Moreover, the description herein given is illustrative of a form of practical application merely. Likewise the joints illustrated at 5 are illustrative also and may be, obviously, constructed in various forms. In the present illustration, however, we have for convenience shown a ball valve for the purpose of equalizing the air pressure in the manner hereinafter described. As shown in Fig. II, a pipe or tubular stem 9 is tightly fitted into nozzles 3. Within the stem 9 is fitted a ball 10, and the construction of said stem is such that the diameter at or near the endsis somewhat smaller than the ball, while at the middle zone it is a trifle larger. This permits the balls in the several stems to adjust themselves, and, under suitable conditions, admit air from adjoining sections during the inflation of a tire or tube. Ordinarily this would happen for all sections as the balls in the several sections would usually adjust themselves in the lower portion of the stems 9. In case, however, that some balls inthe upper part of the tire should fail to properly adjust themselves, two inflating valves 11, have been provided, and in such cases, where necessary, the wheel may be rotated halt way, so that the renewing sections may be properly inflated through the second inflating valve.
In case a tire is punctured while the wheel is in operation, the sectional inner tube or tubes in which the puncture occurred will leak, and the pressure will suddenly decrease thereby causing diiierence in pres sure between the punctured section or sec-- ill) tions and the adjoining uninjured ones. Therefore, the :ball valves (10) of the adoining sections at the joints connecting with the punctured section or sections will be tightly closed against the outer corners of the ball valve pipes (9), and instantly at the same time all the other corrugated tubes will expand toward the direction of. the punctured section or sections, to such an extent as to keep equilibrium of pressure among themselves, compressing the punctured sectional tube or tubes to the minimum space 1nside. the tire, and will, therefore,
maintain the hardness still sufficient for use,
although, of course, the pressure will somewhat decrease according to the amount of leakage of the air. a
If it is, required to deflate the inner tubes in case of need, same can be done by opening theair valves and causing the air to escape.
through the ball valve pipes, but in case where a sectional tube happens, for instance, to be between two or more punctured sections, the section which is not punctured will push its balls in the pipes of the joints at both ends against the outer corners of the ball valve pipes, and close the exits of air therefrom, therefore the tube may burst by excessive expansion. The present inventio has been effected in order to eliminate this trouble, by equipping each of the sectional inner tubes with automatic deflating ar-' ra-ngement, by means of which the tubular plugs (7) are partly drawn out automatically from the nozzles, and the air inside the tube is allowed to escape, thus completing the safety inner tubing.
Having now particularly described and sections, of tubing, end plates on said tubing,
a pair of inwardly projecting cooperating nozzles in each end plate, and adjusting valves, one for each .pair of nozzles.
3.'A pneumatic tire comprising separate sections of tubing, end plates on said tubing, a pair of inwardly projecting cooperating nozzles in each end plate, a tubular stem for one of said pairs of cooperating nozzles, whereby said sections are held in alignment, and valve heads for the other nozzles.
i. A pneumatic tire comprising separate sections of tubing, end plates on said tubing, :1 pair of inwardly projecting cooperating nozzles in each end plate, a tubular stem for one of said pairs of cooperating nozzles, whereby said sections are held in alignment, a valve in said stem, and separate valve heads for the other of said nozzles.
