Referring'irst to Figs. 1 to 3 inclusive,

1 designates a tread, having its inner pe riphery circumferential'ly fand transversely disposed, and with a radially projecting tread wearing partextending therefrom to the tread surface, .which-latter may have any desired contour, although in practice the same is vpreferably made substantially concentric with tlie'resilient and tension elementsof the annular body of the construction, inwardly thereof and supporting` this tread. The .tread is shown with curvature toward the sides thereof, and carried by4 and secured to an outer annular and transversely disposed tension belt 2, consisting oflongitudinal and transverse tensile material, such as fabric or the equivalent in combination with vulcanized rubber, A breaker strip 3 of resilient rubber andtensile material is shown in vulcanized combination on the inner face vof the tensile belt 2. i

ioo

The tread and the y,tensile belt 2 are inf A Vwardly supported upon the outer periphery of the breakerA 3, and a layer of rubber 4, which extends about the sides and incloses an annular and transversely disposed resilient trussing and cushioning portion 5 consisting of rubber or layers of fabrican rubber vulcanized together, and supported on an inner annular and transversely :disposed tension belt 6, of flattenedarch for` mation in transverse cross section, with sides of such belt curved andrextending inwardly and laterall y,in close curvature formation about an annular and transversely disposed inner trussing, and thrust transmitting portion 10.- The tension belt 6,` is shownwith the flattenedV archy formation in spaced relationship to the major transverse axis 7, of the construction, ywith inner annular and transversely disposed cushioning and inflat able support'S. The sides 9, of belt'6 extend in tension about the sides of 8, and an annular and transversely disposed inwardly channeled trussing and thrust transmitting member 10, to terminal parts 11, which are securely anchored tomaintain the belt-6, in tension about such supports. v A transversely dividedv annulus 12, with an outer face', cc'i-'Vfittablel underexpansion against the inner faces of the terminal parts 11, and interlockableby'means of engaging parts 13 thereof, with the parts v14s, on the inner face ofy 10, prevents relative circumferential movement ofthe parts.`

The transversely divided member 12, is also shown with locking parts v15, on the inner face to rco-lock with suitable parts on the fixed rim of the wheel when the inem ber 12, shall be- Suflicientlyjexpa'nded against the terminals 11and` outer seating parts -to provide for placingjor forcing theequip'm menton the rim 21 ofthe wheel, shown in Figs. 1 and 4. The outer periphery of the member 10, is incavated or inwardly curved as at 16, in order to form with ay resilient support 8, a clearance space 1,7,which latf-- ter maybe provided, if desired, with elastic, mobile fluid or filling contenu-although ythe same may be ldispensed within many cases arising inpractice. The resilient support nate ayers of fabric and rubber in vulcanized combinatiomvand iS provided with the inwardly extending porti0n'16, in order to formth'e fluid tight tube 19 which contains the Iclearance space 17. The sides of the inner tensile belt 6 are in close curvature formation around the sides of 8, andthe sides V'of 10, and form stable abutments therewith. The. member 12, provided with transversely disposed locking parts 15,

adapted to interlock with parts 20 on the felly band 21, preventsrelative circumferen# tial movement ofthe parts. The lateral movement is* prevented by meansV of clips y 20,'seciired to the flly'22by means of fastoning devices 23. The outer tensile belt 2 rber10.'-v v my construction f as .in

preferably formed of rubber or alter-V Ais lsubstantially concentricwith the inner tensile'belt' 6 and with the resilient truss- -ing support l8,l inwardly thereof, and re silient trussing support 5, 'and breaker 3 to the tread 1, outwardlyrthereof. The sides of such annular body ofthe resilient trussL ing constructionextend laterallybeyond-the axis of wheel. andl thecpartsof the body outwardly thereof tothe road.'

Referring now to the embodiment seen in Figs. fi to 6 inclusive,.the results attainable are substantially the samel as in the con-H struction justlescribed with reference to Figs; 1 to '8 inclusive, .but in the embodimentsseen in Figsji to 6 inclusive, there silient trussing and cushioning support 23, u Y

between the tension belt 2,l and the tensile belt 6, is provided witlipores or'cells 2l.

The .pores orvr cel-ls are shown disposed in annular and transversely; disposed layers yof.

FigA-shows coiistiuction'nas in Figs. 5k

and 6 with the wheel omitted from the rim. By reference -to Figs. 1 and 4 and the transverse sectional views 2 3 5 and v6, it

will beseen that the longitudinal and trans verse tension in the bel-ts in theconstruction proiffidc continuous annular and transverse tension support in combination with theresilienty support in vulcanized combination,

throughout the depth and width of the annular'body. v`

The inner inflatable and trussingrportion in the spacingfbetween the inner tension belt and the innerannular and transverse trussing member about or with which the tension belt is secured canV be formed with or asV unit .part-of the body'or'be removable there'- from. 'T

In all the embodiments, tension belt of Y and the strains towhich itfmay'be subjected.

The constructionv provides a universally resilient and non-collapsibleannular body which will be absolutely stable in wheel equipment, and provides-for resiliently supporting and balancingload and thrusts so as to secure flexing yand flatteningA action along the plane of road contact of 200 vto 25 slightly more or less, anda corresponding range of altitude of one-quarter to threeeighths `ofan inch as clearly shown by the drawings.

lVhile the embodiments clearly show such standards of capacity and resiliency, in tensile and resilient trussing, as inherent in the construction, it will be obvious that by means of suitable mobile content under suitable pressure in the clearance space of fluid tight tube between the belt 6 and the member 10, .the entire annular body of resilient construction can'be placed under any desired degree of tension so that such body will functionv as a universally resilient truss in tension about theperiphery of the wheel.

The tensionbelt in flattened arch formation is resiliently and positively trussed annularlyand transversely so that the sides of such arch formation are flexible on side abutment supports, Vand firmly secured therewith. This tension belt consists of annular and transverse tensile material in combination with vulcanized rubber, with such standard of strength as required for any special size and character vof construction and thestrains to which it may be subjected. The clearance spaceV or fluid tight tube between such arch formation and the inner support permits of the desired flexing of the arch formation transversely and annularly. The annular and transverse `trussing and cushioning portion, cellular or otherwise as shown, and the outer belt and tread all cooperate as an annular resilient tension trussing portion for the flattened arch formation of the inner tension belt and therethrough to the side abutmentsupports.

Then the construction is submitted'to load from the axis of the wheel, the lstresses are distributed by the rims-to the annular inner trussingsupport and to. the side abutments of the flattened arch vand are taken up and distributed by the transverse tension about the side abutments and by thelongitudinal tension of such arch k formation to and through the annular and transverse trussing and cushioning portion and belt and the tread Voutwardly thereof. Thectread and body flex annularly and transversely-.lin propOrtiontoSuChstrainS, and the capacities of the construction. Y

By means of air or othervsuitable mobile content under lpressure within the annular clearance space, it is not only practical to provide any desired load capacity or standard of ybalance'in the construction but to compensate or even neutralize the compressive strains, by placing the body in a suitable degree of resilient tension.
