Be it known that I, GAn'rnN AJnLLo, a citizen of the United States, residing at New York, in the county of New York and State of New. York, have invented an Improvement on Railroad Car and Track Constructions, of which the following is a specification.

The object of the invention is to provide for railroad cars, irrespective of the elasticity of wood railroad ties, a comfortable, resilient, uniformly plane travel; therefore a combination of an improv-ed rigid track and cars carrying theirown means of elasticity, thereby eliminating the costly and irregular wood tie construction; in other words, there has always been the tendency to do away with the wood tie construction in order to considerably reduce the expenses `of maintenance and troubles inherent thereto, but such an elimination would be impossibl-e were .it not for the adaptation of elastic means embodied into the cars. (To take place of the elasticity of the wood ties.) The importance of such combination is further obvious by citing that with the present wood tie cushioning, a wheel near the joint between two rails, while causing one rail to sag, drags the other down by the joint connection, thereby creating such mechanical disturbances at track joints Vto necessitate frequent inspection and tightening of bolts, not to say that the ties themselves, unless removed when defective, after usage, they cause a train to wabble in all directions and not travel in uniform, perfect plane position.

Tit-h such object in view, I provide an improved rigid track construction in view of cushioningmeans applied into the wheels of cars between an inner and an outer or circumferential portion of the wheels proper.

On the accompanying sheet of drawings forming a part of this specification,

Fig. 1 represents a. cross section through the improved track construction,

Fig. 2 is a cross section through a railroad car wheel embodying its cushioning means,

Fig. is a circumferential section, in plane development, through the cushioning means embodied int-o the car wheels.

Referring by numerals to the drawings, 1 represents the rail, 2 its' rigid bed construction to which it is anchored by anchors B and provided with expansion joints occurand noiseless ring simultaneously with the rail joints. The surface between the Arails is finished Smooth sloping towards a gutter 4 provided with drains '5 at intervals. Thehead of the rail is provided with a drip 6 that serves also to interlock plastic waterproof material 7 to prevent rusting and infiltratil) tion of waterV at oint between rail and track bed, this improvement being very valuable especially for elevated railroad track and at bridge track construction.

8 represents the outer circumferential part of the wheel coming in contact with the rail and t) the inner portion of the wheel. Both portions of the wheel in the direction of facing each other, coneentritally, termi.- nate with flanges 10, which, while designed for the necessary stresses imposed, serve to receive filling material 11, preferably a heat insulator the type of asbestos or one of its late combinations called asbestos wood; the space between the outer and inner portions is occupied by the cushioning means 12 consisting of elastic material the like of rubber, provided preferably with deformations 13 for more eflicient resiliency.

The outer' and inner portions of the wheel are `connected together by means of peripheral, circular, concentric bands 141 of resilient i material preferably rubber or the like, held fast against the two portions of the wheel by means ofsimilar, concentric metallic kbands 15 through bolts 16. The contact between the elastic bands 14 and the metallic parts yof the wheel is through concentric bands 1T of heat insulating material.

ln order to further insure against an aecidental possibility of the outer portion of the wheel displacing itself too far, laterally,

in relation to the inner portion of the wheel, metallic guards 18 may be placed at intervals radially; but in case of electric railway, these guards, through a sj'iringy universal. joint 19 would keep arm 2O in contact with the outer portion of the wheel without touching its outer cushioning means, thus forming a continuous resilient electric contactbetween the two metallic parts of the wheel for the necessary. negative electrical discharge to the-rails. j Y

The brake drum for the .ear wheels may be incorporated onto the inner portion of the wheel or separately as at V21, acting o the same wheel axle mit.

l claim: Y

1.111 a railroad car and track construclil() llO tion, a wheel consisting of an outer and an inner portion concentrleally spaced in relation to each other, embodying in the concentric space between them lianges projecting from each portion'toward the other portion, heat insulating means between each set of flanges and cushioning` means between the insulating means. y

2. A wheel as specified in claim l in combination with an electrical conductor secured at the inner portion ofthe wheel and extending toward the outer portion, said conductor to serve simultaneously as a guard against ultimate lateral` displacement of one portion of the wheel in relation to the other.

3. In railroad car and track construction a wheel as specified in claim l comprising lateral, peripheral elastic means outside the cushioning means. y

4. In railroad car and track construction a wheel as specifiedin claim l comprising lateral or peripheral elastic rings` between thetwo portions of the wheel and insulating rings between each of the portions of the wheel and the outer elastic peripheral means. v
