Beit known that I, FUnNnr y Coalgate, .ii1 the county of Coal and State of 'Oklali'o'inm have invented a vnew and l 1seful i Tire', of-a'vhich the `following is a specifica-4 tion.

' Ilie device lforming the subject `matter of thisf'application is n.resilient tire and one 10 object of the invention is to provide a novel form of casing.

Another object of the invention is to pro. vide-a structure of the type above rmentioned in which the casingcoperates in a novel 15 manner with'the side walls ofthe rim'band.

i A further'lobject of -the inventionjis .to provide novel `means forpreventing creep-v ing ofthe casingupon or withv respect' to.

' It is within the scope of thelinvention to 0f devices 0f that type to which the present invention appertains. .Y

lVith the above and other objects in viewA whichwill appear as the description lproceeds, the invention resides in the combinationl and arrangement of parts and in the I details of construction hereinafter described and claimed, it. being ,understood that changes 'in the precise embodiment of the invention herein disclosed can be made W1th.

in the scope of what is claimed without def` parting from the spirit of the invention.

, In caiiryi-iifg:out the present invention-and referring particularlyto Figs.' 1, 2, 3 and 4,

the invention is shownl :is-comprising a felly j 1-.circum`scribed by va. rim liand2.v T he'rinband 2`preferably vis fashioned from metal .and is provided upon` itsjunder face, as shown in Fig. 1, -with transverse lugs '3 received in transverse recesses in the elly 1.

The functionof the lugs ,3 -is .to `prevent rim band-'2 from 'creeping circumferentially i on the'j'felly l.. .'-Ihe rim-band 2 comprises' y side. walls .4', the outer faces of' which slant, or converge 4from each other-as theyextendv toward tliefelly 1. The rim band 2 maybe "i shown in Fig.` 9, openings 9 may fbe` formed in one segmentl of the rim'band adjacent its end, the openings .9 being adapted to receive tongues 10 struck from-the' other segment of the rim band. The side Walls 4 of the rim band 2 are provided lat intervals with notches 11. v

`Vhen the invention is embodied pneumatic form there is employed'a tube 12 inflated by means of a Valve 14 extended through the'nfelly 1.' Interposed between the tube k12 and the rim band 2 is atroughshaped, resilient, metallic, inner ,stripi 15 which rests immediately upon f the rim The invention includes an outer, metallic trough-shaped sti-ip 16y provided along its longitudinal edgeswith hook-shaped beads 23 defining flange'sl. The strip 16 may be resilient'df desired, to the end that it may flatten slightly 'in its `tread, portion.` The flanges 17' are .equipped with laterallyeX-- tended projections 18 receivedin'the notches 11 of the side vwalls 4 of the rim band `1. As shown in Fig. 4,. the l,projections 18 may be of flared formand When'this construction is employed, the edges of the notches 11 are the strip 16. In practical operation, the cas- ,firmly attached thereto by cementmg or if is provided upon its Iinner'face with transing 2.0 is built up upon the .strip 16 and is otherwise. The strip 16 is not attached `to 'the tube 12. The longitudinal edges of the casing 20 are grooved as shown at 421 to f.

define an inner wing 22 and an outer Wing 24. The flange 17 enters the groove 21 and the' inner wing 22 is firmly bound between the flange 17 and the body-portion of the strip 16. free, and is adapted to reciprocate upon the inclined face 5 of the side Wall 4.when 'tite ca'singl20 and the tube 12 are compressed.

Referring to Figs. 6, 7 and 8, wherein a modified form of the invention is shownthe felly is denoted by the numeral 25 and the rim band is shown at 26. The-rim band 26 "verse lugs 39, corresponding to the lugs 3 of Fig. 1 and received in the transverse vgrooves in the felly 25, to the end that the rim band may not creepcircumferentially on the felly.

The side walls of the rim band 26 are' shown at 27 and the outer faces 28 of the side Walls are inclined, as described in connection with the faces' of the side Walls 4, and for a like purpose. The inner, trough-like metal- Y lic strip is shown at 29 and is equipped with a hook-shaped bead 30 defininga flange 31. The strip 29 is attached firmly to the casing 32 and the latter' is grooved`r as shown at 33 to receive the anges 31, the inner `wings 34 struck laterally from the`flanges"31-and tongues 37 are struck' froinzthefside walls 27" and the outer wings 35 being of the-form hereinbefore described and having the functions hereinbefore set forth so far as the bead 30 and the inclined face'28 are concerned. 1 f

In the place ofthe anti-creeping means 18-11 hereinbefore' forth," tongues are of the rim band 265 lThe' tonguesif 'and 317'- interengage, as clearly shown in F ig. v8, to` prevent the casing 32 and attendant"partsl from creeping on the rimband 26; The"l tongues 36 project in opposite directions andl the tongues 371 are shaped -'a'ccordingly. Therefore, the casing 32 and' attendant parts l canno'tcreep' in either direction, circumfe'f' `entially of the rim band.

In the form under discussion, helical springs 38 are connected one end yto the rimv bandl or `bear loosely thereon', as' may be,` found' expedient.VA The' springs 38 are of con?" ical` form,` the smallest, -terminal convolu` tions of the springs38 terminating" in fin- The outer wing 24, howevenis `at 41 and the rim bandat 42.

y"gers" 4.0,passingy through thefm'etallic strip 29 and entering the tread portion' of the casing 32. Although the casing 32 ordmarlly is secured so firmly to the strip 29 that relative movement between these parts is lmpossible, it will be observed that the fingers 40 aid in preventing relative movement between the casing and the strip Conversely, the strip. 29 forms a firm place of attachment for the fingers 40 and prevents the casing 32 from being worn by the movement of the outer'ends of the ysprings.

The anti-creeping means 18-11 of Fig. 3 is applicable vto that formfof theinvention whichl is disclosed' in. Fig. 7,1' and-.the anticreeping means shown inFig. 8 may. heemshown in Fig. 6.l

In Figs. 11, 10 andV 12, thefelly is shown Relative movement between these parts is prevented andat 39 as hereinbefore described.- The lside walls of the rim band are shown at 43 andthe outer faces of theside walls are inclined asI shown at 44 for the'purpose hereinbe'fore set forth. The outer, metallic band is shown at 45 and'corresponds ,to the bands or strips 29 and 16.I The hol-shaped beads are `.shown at 46, the same defining flanges 47.` Referring to F ig.l 10, the beads '46 are notched to define shoulders 48.v In the' rim band 42 at the sides of the felly 41, lopenings 49 are-formed.A` Into ,the openings 49"project bends or projectionsT 5 (l`v formed up'on'tlieinytermediate. portionsof, anti-'creeping elements, .the -antircreepingelements embodymg arms 51 terminally engaged with the .shoulders 48. The anti-creeping elements are resilient. l

Having thus described the invention, what vis`claimed is f 1. vIn-a vdevice of .the.classI described, a rim flband 'embodying side walls; and a casing :providedalong its edges 'with inner. wings 'and''outer resifl'ient' wings which are A independenti fof? the inner mvngs, the inner yWings lying'i betweenrzthe side walls,- and theiouter `wings ,'engaging'tlie outer. faces ofthe -:side
