Within and attached to the sheet metal. wall E is a sheathing J, preferably also of sheet metal. n from the wall E by means of the blocks or bodies of material K;-this materialbein preferably of 'wood,- fiber, or other materia which has. relatively small ca acityfor the conduction of heat. Preferahly, as shown in" Fig. 2, these insulating bodies K, as I have termed them, are arranged in staggered relation with the elements C forming the framework of the wall structure proper of the car, Preferablfy, the attachment of the l E and the sheathin J is such that there'flis no metal contact tween the wall andv the sheathing For example, the insulatin .blocks' K may be riveted-to thewall- -by the rivets k, the

For example, the floor of the car may roof structure bein provided with the perforation or series 0 perforations u by means of'which the air enters the interior of the car. by the dotted lines in Fig. 1, the air circu; lated between the wall E and the sheathing J will immediately escape from the car. J will also have If the ventilators are open, as shown the openings or series 0 o enings V which may be closed or partial y closed by the shutters W. By this means a part of the heat from the radiating e car.

By these several features of construction the conduction and radiation of heat through 0 may be the outer wall will be materially checked and diminished. It has been found that in winter time the inner surfaces of the walls of the railway cars of steel construction are frequently so'cold, due to the ready conductivity of the metal composing the wall structure, as to be very unpleasant. and detrimental to health. 'Thisis particularly so in By the revision of the sheathing J and thecircu ation of heated air along the outer surface of the sheathing the inner surface of the wall of thecar, even though the wall be made entirely of metal, is kept at a comfortable temperature. This result is furthered by the use of the insulating blocks K for connecting the sheathing with the-wall structure proper of the car and by arranging these connecting bodies, whether they be of what has been termed insulating material or not, in stagred 'relation with the metal parts, the alias O, which-connect the outer sheet metal since the several paths for the conduction of the heat are thereby-lengthened.

- By a suitable. re lation of the various devices for control ingthe inflow and discharge of air to and from the airs ace N,

the air, which is circulatedthroug such space, may be. taken either from outside the .car and discharged outside the car or from within the carand dischar d outside of the same, which will provi e' 'a means of v ventilation, or maybe taken from within the 'car and discharged backinto the car, which will be desirable in very cold weather and wall D with-the inner sheet metal wall E;

when the car is first heated up, as it will involve a saving of heat.

In summer time the inner surfaces of the walls of cars of ordinary steel construction have been often rendered unendurably hot, particularl when the train travels over wide stretc es of unsheltered country in the sunshine and with the temperature very high. In such case, with the construction of wall above described, the temperature of the inner surfaces of the wall and of the atmos here within the car may be very considera ly modified, since in such wall structure the metalcon'stituting the inner surface of the wall is insulated from the metal with which the suns rays come 1n direct contact, and furthermore by the circulation of air established through the airspace N as a result of the heating of the upper part of the car structure to a greater extent than the lower art.

I have s own the car constructed so that the air from outside of the car will enter the Y I claim:

be employed for introducing the air from outside the car into such air space.

1. In a railway car, the combination with anexternal wall structure comprising two sheet metal walls and supports for the-same arranged between said walls, -of an inner sheathing spaced from said external struc-. ture so as to constitute a passageway for the circulation'of air which is open atthe top, and means for opening communication I between the lower end ofsaid passage way andthe interior ofthe car, or the outside into said passage way either from the intecar, the combination with rior of the car or from outs ,de the car, the
