WHEEL.

Specification of Letters P n Patented Dec.31,1912.

Application filed December 6, 1911; Serial No. 664,151.

Be it known that I, ANDREW McKiLmr, a citizen of the United States, and a resident of Downieville, in the county of Sierra, State of California, have invented a new and useful Improvement in iVheels, of which the following is a specification.

' My invention is an improvement in' wheels ,-and has for its object the provision of a simple, strong, light weight wheel wherein is provided a' pneumatic cushion between tlie'spindle and the tread pifitected on all sides. from external injury, and imparting to the wheel a. great amount of resiliency, while of small size and inexpensive.

In the drawings: Figure 1 is a side view of the wheel; Fig. 2 is a similar view, with the side plate removed; Fig. 3 is a vertical section inthe plane of the wheel;- Fig. 4; is a vertical section transverse to the plane of the wheel; Fig. 5 is a front view of one flange of the hub; and Fig. 6 is a section on the line 6-6 of Fig. 1. In the present embodiment of the dnven- 'tion the spindle 1 oft-the wheel is provided with an annular rigid collar 2 atv the inner side of the wheel, and a nut 3 en ages the opposite-end of the spindle outside of the wheel. The wheelgconsists of a casing composed of a disk 4 having a lateral marginal flange 5 and a cover plate 6. The flange 5 is convex from side to vside of the wheel to Lform a suitably shaped tread, and the edge of the flange remote from the disk is flanged inwardly, as shown at 7, and tli'e'edge of the cover plate tits against the said flange 7. The plate- 6 is provided wit-h a series of air outlets and with a central opening 9 for the spindle.

A hub 10 is arranged on the spindle, the

said hub having a flange 11 at the end adjacent to disk 4, and a flange IZat the opposite f end of smaller radius than flange 11. The

at the spindle, and the-opening 1 disk 4 is provided with acentral opening 13 3 is crwered by a cover plate-14 secured to the disk by] bolts 15. The disk l is il QIJHOVlded witlt a series. of air iiilet o1' c 'u'gs it rat-hot out or nozzle,

direct ion to the movement of the wheel. shield. lll'lllt shape of a seiuiruaailar plate 17 is arranged in front of each opening. the

curved edge of the plate being secured to t lie'face ot the disk by lH'ClS 13. Each shield is cupped outwardly, and e -screen 19 i of gauze extends between the free edge of each shield and the disk 4. second hub 21 encircles the spindle adjacent toi the collar, and the opposite end of the hub from the collar is received in a recess 2-2 in the end of hub 10. A packing 23 is' arranged in hub 21, and the said hub is provided with 1 three-radial arms 20, the arms being-arranged adjacent to the plate 6 and being at angles of 120 with respect to/euch other.

' Each arm 20 extends to a point adjacent, to flange 5 and is then bent laterally toward disk 4, and thence inward toform an arm 7 24 substantially parallel with arm 20 and; .spaced apart therefrom. The free inner ends of arms 24' are connected by'a ring 25, each arm being secured to the ring by rivets or bolts 26, and the ring'is concentric with the spindle. i

A stub shaft or bolt 26 is journaled parallel with the spindle in each pair 2024 of arms, and a nut 27 engages each bolt outside of arm 2+1. A wheel is journaled on each g0 bolt, and each wheel is composed of a disk 28 having a hub 29 encircling the bolt and p'xtend ing on each side of the disk. A rim 30 is arranged on each disk, each rim having on its inner face and at its transversecenter 35 a pair of spaced ribs 31 between wltrch the. edge of the disk is received. The rim ex- 7 tends beyond'both faces of the .disk and is slightlyfconvex froin'side to'side,' and a v packing is arranged in the hub between 00 t-he same and the bolt. -Each'of the wheels,

composed of disk 28, hub 29 andrim 30,.engages at its inner side the outers urface of :1 pneumaticcushion 33 of annular form seat-' ed on a rim 34 between ribs 35 and 35, one at each side'ot' the rim.

The ribs 35 and 35 are as before stated on the rim 3- and flanges 41 and 4-2 are integral with the said riin, the said flanges be- ,ing at opposite edges of the rim. and extending radially with respect to the rim in opposite direction. The flange 41 extends nwardly toward the spindle 1, while-the flange 42 extends outwardlv toward the tread. and thOJZree edge of the said flange. is ottset laterally initLsecured to the inner "are of the disk 4. as iihlicatcd zit-43. The flange 4-1 and the disk tare connected by 3 lie-Its -38. and tilt flanges 11 and 12 (it the dial slots 44 at each of the bolts, for permitting the movement of the bolts'radially with respect to the hub. 7 he spindle 1, the hub 10 and the arms 20, may thus move radially toward the pneumatic tire within limits prescribedby the diameter of the opening or slots 44. Valves 36 are-provided for inflating the cushion, and one of the ribs 35 is provided with a radial flange 37 fitting outside of flange 12, and bolts 38 are passed through.

flange 37, flange 12 and flan e11 parallel with the spindle. The flange I1 is provided with open1ngs 39 and with a central opening 40 for hub 10 (Fig. 5).

In operation, the flange 5 is the tread of the wheel, and when any portion of the said tread is inengagement *with the ground the -'spi'ndl'e is supported by the wheels 28-2930 with the'pneumatic cushion-be-1 tween the said wheels and the hubof the 1 spindlar The three wheels.;prevent dislocation of the pneumatic tire or cushion, and .-the spindle .is plwaiys perfectly cushioned b the tire.- The-wheel has thusall the -a vanta es of the pneumatic cushion without any-o the disadvantages. .The tire is per- .fectlyprotect'ed" from any kind of injury.

The wheel is'easily and quickly assembled and'ma'y be of any desired weight and size. -The interior of the wheel is provided with through the openings 16 and passing out .through openings 8. The arrangement of the shield 17 insures a circulation, since they 7 are arranged wit-h the open side of the shield forward, and.the air .is scooped up by the shields and passed through the openingslfi. In use, when the tread 5 of the wheel engages. the ground, the spindle and the wheels supportedon' the arms 20 may move with respect to the pneumaticltire supported by the disle t, this movement being permittedbythe slots 44. The tire is fixed with respect to the disk 4, by means of the ring 42 before mentioned, the said ring holding the tire rigidly in place with respect to'the disk. Three'points of suspension areprothe said wheels. The resilienc matic tire is thus obtained wit out any dancasing having one S e op n, P }1; for the side, said leasing having a central vided, namely, the wheels'om the arms 20 and whatever, the position of the wheel the pneumatic tire will always be supported by of the pneutirely protected by the. casing.
