WHEEL.

To all whom/t may concern." .u

lle it known that I, `W1LLIAM Siemen, a citizen ci the United States, residing at Chicago, county oiCook, and State of Illinois, have invented certain new and useful Improvements in l/Vheels, oitwhich the following is a specification.

This invention relates to an improved vehicle wheel, the principal objects being simplicity, cheapness, lightness, strength, and resiliency. Numerous other objects are in contemplation as well, as will more fully hereinafter appear from the specification p and claims, and from the accompanying Figure 1 is a side view of a wheel embodying my invention, `one casing section and one cushioning element being removed to exhibit certain of the interior parts;

Fig. 6 is a cross section, taken on line 6 6` of Fig. 2;

The suggested embodiment of my present wheel shown in Fig. 1 employs two complement-ary casing sections` 11 arranged to pro` vide between them a chambered space within which certain resilient elements are contained. Each casing section is shaped to provide a peripheral flange 12 adapted to receive reinforcing angle rings 13 upon which are mounted divided rim sections 14, such, for example, as are shown in Figs. 2 and 3. Flanges 15 are formed on the rim sections to grip a tire casing 16. The rim, tire flange, and tire construction may obviously be varied to suit requirements, an

i alternate arrangement being reserved for consideration in connection with Figs. 9 and 1.0, presently to he described.

Specification of Letters Patent.

is a similar view, taken on line 1n Fig. 2, consists ofV two `complement-ary sections conveniently secured together as by bolts 20 '(see Fig. 1). The casingsections are also held in unitary relationby some such device as tie bolts 21\ locatedat convement intervals. Extending radially from the hub are spokes 22 whose inner "ends may be appropriately conligured,as by means of grooves 23, to enter` into locking engagement with `the hub which is formed with` co# operating elements 24 for this purpose. The outer end of each spoke may be in the `form of an eye 25, through which extends a circular core piece 26 occupying a central position within the peripheral channel 17,"each i spoke eye 25 being preferably welded to the core piece..`

The parts thus far described include a hub which is loose with respect to the wheel casing, and a series of spokeslixed to the hub and to the core piece which lies within the peripheral channel or' the casing. The` remaining wheel parts are formed from some material having resilientproperties, such, for example, as rubber, or a rubber composition, and include a plurality of elements 27 1 equal in `number to the number of spokes, each element -being in the general form of the letter l-l with a straight connecting portion 28, the remaining portions 29 and I30 being each shaped in the form of an arc struck from a common center. The straight portions 28 of `these resilient elements 27 are arranged to lie within the spoke channels 18, the arcportions 29 within the peripheral channel 17 and the other arc portion 30 within the annular channel adjacent the hub. As will appear from the several ligures of the drawing, the resilient elements 27 are formed around the spokes 22 and the core piece 26this being accent plished either by the process oifmolding, or by forming each element of two sections held in complementary relation when posi` and at the same time be tree to operate with `rmentari sept. a, 1919. Application lpfiled Mayll, 1918.r Serial No. 233,826.

greater freedom, annular channels 31 are provided exteriorly thereof (see Figs. l and 2), and pockets 32 interiorly thereof, the pockets and channels being preferably arranged in alternate order.

Referring now to the construction shown in Figs. 8, 9, and l0, it will be noted that the Wheel is in all substantial respects the same as the device shown in Fig. l. Accordingly I have designated the casing sections, the interior channels, resilient elements, etc., by the same numerals as those applied to the corresponding parts of the wheel already described. The principal point of departure is in the tire rim which dispenses with the reinforcing angle rings. Asbest shown in Fig. 9the casing Hanges 13 form the elly on which the tire is mounted, demonntable rims 33 being secured tozthe sides of the casing section by means of the tie-'bolts 2l. Each of these demountable rims is Jformed with a tire retaining flange 34C and a casing engaging fiange 35 around which fits a ring 86. It is apparent that the tire flanges may be removed by simply unscrewing the nuts from the bolts 21, whereupon the rings 36 may be taken ott, permitting the tire rims 33 to be demounted. f

The present wheel is characterized by certain interior channels formed adjacent its periphery, adjacent its hub, and in the spokes, and by the presence of resilient elements Within these channels tending to keep the hub centered with respect to the wheel periphery. This construction is such that shocks and -bumps are easily and effectively absorbed without the necessity of an air cushion in the tire or elsewhere.

I claim:

1. A vehicle wheel comprising, in combination, a hollow casing, a hub movable radi- Copies of this patent may be obtained for ally of the easing, means for ceutralizing the hub relative to the wheel consisting olt a plurality of spokes lixedly secured to the hub and radially extending therefrom, a ring-shaped member loosely arranged within the wheel casing in proximity to its rim and connected with each of the spokes, and a plurality of resilient elements surrounding the ring-shaped member and spokes and extending into the hub for norinally maintaining the hub in a position centrally oil the wheel, substantially as described.

2. A vehicle wheel comprising, in combination, complementary sections arranged to provide between them a peripheral rim channel, spoke channels connecting therewith, and a circular channel opening toward the center of the wheel, a hub disposed hetween the wheel sections and slightly overlapped thereby, spokes secured to the hub and extended through the spoke channels, a core extending within the peripheral channel and connected with each spoke, and re silient elements interposed between the huh and the Walls composing the various channels within the whcel, substantially as described.

3. A vehicle wheel coniprising, in combination, a rim, a hub, and spokes extended between the rim and hu'b, the spokes heilig fixedly secured to the hub and loosely secured to the rim, there being intercomnnmieating channels formed in the rim, spokes, and hub, and resilient elements positioned within the communicating channels, and extending rom the rim through the spokes into the hub and tending to centralize the hub with respect to the wheel, substantially as described.
