Application filed April 4, 1924. Serial No. 704,200.

To all 'whom z't may concern:

Be it known that I, FRANCE AemoHnK, a citizen of the United States, residing at Chicago, in thecounty of Cook and State .5 of Illinois, have invented certain new and useful Improvements in Car Wheels, of which the following is a specification.

This invention relates to new and useful improvements in car wheels, principally of the type used onvehicles adapted to travel 7 over ralls.

One of the importantobjects of the present invention is to provide a car wheel of the character described which is of such a construction as to eliminate a great deal of the unnecessary noises now made by the vehicles when-the same are traveling over the rails.

- A still further'object of the invention is to provide an improved car wheel of the above mentioned character, wherein the parts are so arranged as to enable the same to be readily disassembled whenever necessary in order .to replace the worn parts.

A further object of the invention is to provide a car wheel of the above mentioned character, which is simple in construction, inexpensive, strong and durableand furthermore adapted for the purposes for which it is designated.

Other objects and advantages of this invention will become apparent during a course of the following description.

In the accompanying drawing formin a part of the specification, and in which llke numerals designate like parts throughout the same, V

Figure 1' is a side elevation of my improved car wheel,

Figure 2 is a vertical section taken therethrough, and

Figure 3 is a sectional view taken approximately on line 3-3 of Figure 2.

V In the drawing wherein for the purpose of illustration is shown the referred embodiment of my "invention, t e numeral 1 designates the body portion of m car wheel and the same is cast of any suita 1e metallic material in the manner well known in the art. Extending circumferentially around the peripheral face of the body portion is the rib or flange2. The portion of the peripheral face of the body rtion 1 between the rib 2 and the rear of the wheel the front face 5 of the body portion of the provides a brake drum 3 for the purposes also well known in the art. 7

The body portion 1 is further provided on the opposite side of the rib 2 with the annular groove 4 which is also formed in the peripheral face of the body portion and wheel is cut away to provide a flange 6 for the purpose hereinafter to be more fully described. The diameter of the front face 5- is less than the diameter of the. body portionl of the wheel as is clearly illustrated in Figure 2 of the drawing. Adapted to be securely supported in the annular groove 4 is the packing ring 7 which is formed of any suitable flexible material, preferably rubber, although it is to be understood that any other suitable material may be substituted therefor, and I do not wish to limit myself to the particular kind of material which is to be used. When the rubber ring 7 is in position in the groove 4, the tread portion 8 of the wheel is adapted to extend therearound and the tread portion is also in theform of a ring and is provided with the annular flange 9 which extends inwardly therefrom a cooperates with the flange 6 formed on the front face 5 for retaining the rubber ring 7 in position within the groove 4:. As is further shown in Figure 2 of the drawing, the annular flange 9 is slightly s5 spaced from the flange 6 and this space 10 provides a means for permitting the inward movement of 'the tread portion 8 in such a. manner as to prevent the possibility of the flange9 on the tread portion from coming '9 in contact with the flange 6 on the front face 5 so as to cause any unnecessary noises. The rear face of the tread portion 8 is provided with the usual bead 11 which is adapted to travel in the groove provided in. the rail over which ,the wheel rides or' is adapted to abut the edge of a flat rail in.

'themanner well known in the art.

For the purpose of retaining the tread portion 8 in position on the flexible packing ring, I provide the retainin rin 12 which fits flush against the front face 0% the body portion and the tread portion res ectively, and the retaining ring 12 is provided with suitable a ertures adapted to register withthe threa ed apertures 13 provided in the front face 5 of the wheel body andsuitable fastening bolts such as shown at 14:-

are adapted to extend through the openings in the retaining ring and are threaded into the threaded openings 13 in the body portion whereby the ring 12 will be securely.

clamped in engagement with the front faces of the wheel body and tread portion respec-' tively, in thejmanner clearly shown in the drawing. Any number of these fastening bolts maybe provided as is deemed necessary. The body portion -1 is further provided with the usual central opening 15 through which is adapted to extend the axle ,.0f the vehicle in the usual manner.

By providing a car wheel of the above mentioned character, the usual noises made by the cast wheels now in use upon convey- I rib,.a packing ring of ances which travel over rails are eliminated and furthermore the parts are so arranged as to enable the same to be readily disassembled in order to replace the worn parts with new ones. Further a car wheel of the above mentioned character, will be strong and durable and may be manufactured at a ve low cost.

ile I have shown the preferred embodiment of my invention, it is to be understood that various changes in the size, shape and arrangement of parts may be resorted'to without departing from the spirit of. the invention and the scope of the appended claims.

Having thus described the invention,

what I claim is 1. A car wheel comprising abody portion, an annular rib extending upwardly from the peripheral face of the body portion adjacent the rear face thereof, said .body portion having an annular groove formed in the periphery thereof adjacent the front face of the bodyportion and ad'acent the annular exible material in said oove, a tread portion extending aroun said packing ring and abutting'the annular rib, and means for securing the' tread portion on the body portion.

2; A car wheel comprising a portion, an annular rib formed on theperlpheral face thereof adjacent the rear face of the body portion, said body portion having an annular groove formed in the periphery thereof adjacent the front face of the body portion and adjacent the annular rib, the out face of the body portion bein cut away around its outer edge to provi e an annular flange, a packing ring of flexible material supported in said oove, a tread portion extending around sa1d packing rin and having the front face thereof provide with an annular flange adapted to'coo erate with the annular flange on the front ace of the body portion, the rear face .of the tread portion abutting the annular rib, and means and having the front face thereof provide with an annular flange {adapted to cooperate with the annular flan e on the front face of the body portion, the rear face of the tread portion abutting the annular rib, and

means for securing the tread portion on said body portion, comprising a retaining ring fitting against the front faces of the tread portion and the body portion respectively, and fastening bolts extending through sa1d retaining ring and threaded into the body portion.

In testimony whereof I afiix my signature.

, FEANOK AGNIOHEK.
