RESILIENT WHEEL on TRACK ROLLER.

'Appiicaaon'med May 21, 1924. serial no. 714,920.

(FILED umana THT: ACT'OF Manent', 1883, z2 STAT. L., G25.)

lTo all whom t may concern.'

Be itA known that I, LUOIAN B. MOoDY,a citizen 'of the United States, and a legal resident of county of Beadle and State of South `Resilient Wheel or Track Rollers, of which the following is a specification.

The invention described herein maybe Vused by thel Government, or any of its oliicersor employees in prosecution of work for `the Government, or by any other person in the United States, without payment tome of vany `royalty thereon, in accordance with the' act of March Vv3, 1883.

The subject of this invention is a resilient wheel or track roller for vehicles of the track-laying type. Y

ln Vvehicles-of vthe track-laying type, the ",weig'l'it oi' the vvehicle is supported` on trucks, which carry wheels or rollers riding on a 'continuous Vrail formedjon the inner side of an endless flexibleflink track. As the rollers are of metal the-'shock caused by irregularities in the tracks is considerable.

jMy invention resides fin providing a resilientroller which will include the usual wearing qualities of a metal roller and at the same time considerably .reducethe shocks "encountered during travel. I, also, provide A"means for venftilating the roller to prevent undue heating oftheQresilientelements and I position the resilient' elements so'that they mayv be readily replaced or removed by removing only the hub cap and rim without disturbing the primary assembly of the wheel.

To :these and other ends, my invention consists in the construction, arrangement, and combination of elements described hereinafter and pointed out in the claims form'- ing a part of this specication.

A practical embodiment of my invention is illustrated in the accompanying drawing, in Which,

' Fig. 1 is a view of my improved wheel in elevation; and

Fig. 2 is a longitudinal sectional view taken on the axis of the wheel.

Referring to the drawing by numerals of reference 10-10 indicate separable metal rims, conveniently flanged, each of which is formed with an inwardly projecting annular web 11, provided with a plurality'oi:l ports 12, as

clearly shown in Fig. 2. The innersides of f bands being arrested by a shouldered annular portion 18 `centrally disposed on the hub 17 and the bands being supported by the f pont-ion 18 and annular flanges 19 formed on the hub. The rims are movably conned between the outer flanges 13 of the base bands 14 and a hub cap- 20, secured to the hubby means of screws 21 to maintain a rigid assembly. The rims are spaced from the hub aboutV their entire peripheries asshown at 22 thereby permitting the hub and its attendant structure to yieldingly rest Aupon yand compress the resilient members 15.

The v'hub 17 carried suitable friction reducing elementscomprising rollers 23, while between the Vroller cages, I, provideY a spacer 24. r*1F-he rollers run on bushings 25 and embrace a 'gudgeon 26 passing transversely through the Vhub and secured to the truck 27 of the vehicle.` Positioned at either end offthe hub and embracing the gudgeon are sleeves 28 carrying dust washers 29 and maintaining encircling pegged washers 30 and 31 in Contact with the hub 17 and roller bushings 25.

The gudgeon 26 is provided with an Oil valve 32 at one. of its ends and it will be understood that the gudgeon is hollow and formed with oil ports (not shown) for lubricating the rollers 23.

To replace a resilient member, it is only necessary to remove the hub cap and rim when the resilient member may be pried Oli and a new member mounted on the base band, or if desired, the base band may also be removed.

While in the foregoing there has been illustrated and described such combination and arrangement of elements as constitute the preferred embodiment of my invention,

it is nevertheless desired to emphasize the fact that interpretation of the invention should only be conclusive when made in the light of the subjoined claims.

I claim:

l. A resilient wheel embodying separable rims each Jformed with an inwardly projecting annular web, base bands spaced from the rims and abutting the webs, resilient elements carried by the base bands and engaging the rims, a hub within the base bands, annular lianges formed on the hub for supporting the bands and spaced from the webs of' the rims about their entire peripheries, a centrally disposed annular portion formed on the hub for supporting and spacing the bands, caps secured to the hub and abutting the web of the rims for maintaining the rims and bands in assembly, a gudgeon, and anti-friction elements interposed between the hub and the gudgeon.

, 2. A resilient wheel, embodying separable rims each formed with an inwardly projecting annular web, base bands spaced from `the rims and abutting the webs, resilient elements carried by the base bands and engaging the rims, a hub within the base bands, annular flanges formed on the hub for supporting the bands, an annular portion formed on the hub. intermediate the flanges `for supporting and spacing the bands, means secured to the hub and abutting the webs of the rims for maintaining the rims and bands in assembly, a gudgeon, and anti-friction elements interposed between the hub and the gudgeon.

3. A resilient wheel'embodyingy separable rims, base bands spaced from the rims,

, resilient elements carriedby the base bands and contacting the rims, a hub within the base bands and spaced from therims, a centrally disposed annular portion formed on the hub for spacing the bands, a gudgeon, land anti-friction elements interposed between the hub and the gudgeon.

4. A resilient wheel embodying separable rims, base bands spaced from the rims, resilient elements carried by the base bands and contacting the rims, a hub within the base bands, a centrally disposed annular romkthe rims, resilient elements'carried byy the base bands and contacting the rims, Vthe sides oi? said resilient members beingezsr-v posed to ventilation, a hub within the base band, a gudgeon, and, anti-friction elements interposed between the hub and the gudgeon. 6. A resilient wheel embodying separable rims, base bands within the rims, resilient elements carried by the base bands and contacting the rims, a hub within the base .bands, means for spacing the base bands, a

gudgeon and anti-friction elementsrinterposed between the hub and the gudgeon.

7. A resilient wheel embodying a rim,V

base bands spaced from the rim, resilient elements carried by the kbase .bands and contacting the rim, a hub within the base bands and spaced. from therim, caps carried bythe hub and abutting the rims for maintaining the base bands in position, a 'gudgeom and anti-friction elementsVv interposed between thehub and the gudgeon.

8. A resilient wheel,` embodying afrim base bands spaced from the rimto permit circulation 'between Vthe bands and rim, resilient elements carried by the base bands and contacting the rim, a hub within the base bands andr adapted torspace them, a e

gudgeon, and anti-friction elements interposedbetween Vthe hub and the gudgeon."
