Refrigerator-Cars and the like,of which the follmving is a specification.

My invention relates to the heating of railway cars. particularly by steam, and the 1 primary object of the invention 1s to provlde a suitable equipment for supplying'heat, as occasion may require, to railway cars such, for example, as refrigerator cars Which ordinarily do not require heating but which it is desirable to heat during certain periods.

and in certain seasons When ce'rtainkinds of fre ght, such, for example, as fruit or vegetables are transported.

It is customaryto use refrigerator cars for the transportation of fruit, vegetables,

and like perishable commodities in certain seasons or in travel through certain" parts of the country WlilllOLIlT having suchcars iced. W hen such commodities are subjected I in transit to comparatively 'loW temperatures not only is icing unnecessary but it is desirable to heat the cars in order to avoid the danger of freezing-although possibly only for a part of the journey as, for eX- ample, When fruitis transported from a tropical or semi-tropical climate to more northerly regions. However, this heating of refrigerator cars, desirable as 1t 1s under some circumstances, has not ordinarily been done, in the first place, because of the cost involved in equipping such cars With the heating systems of the type customarily used on railroad cars, which is very high considering the comparative infrequency of the, occasions demanding the heating of cars of this sort, and, in the second place, because of the space which the heating coils of such systems occupy in the car, the permanent.

installation of heatingcoils in the car decreasing the carrying capacity of the car Without serving any useful function during the larger part of the time during Which the car is in service. The employment of stoves in this connection'is objectionable as stoves require frequent fueling and constant attention and, moreover, are likely tosetfire to the train in case of accident.

My invention providesjavery satisfactory heating equipmentffor cars of th s type cone sisting, first, of steam heating or radiatlng derneath the same, and is adapted to convey steam from the locomotive boiler, or other common source of supply of steam common to the several cars of the tram, and deliver the same preferably inautomatically regulated quantities to the heating element or elements When the same are 1n operative position, and, third, an air circulatory sys-' tem Within the car, preferably also a permanent installation, with which the heating elements cooperate to produce auniform or relatively uniform distribution of" heat through the entire, car. The air circulatory feature of my invention is not perhaps absolutely essential but is, nevertheless, a highly desirable feature of the invention. lVith an equipment of this sort the cost of heating refrigerator cars, and the like, is sufficiently reduced and the space in the car sacrificed to this purpose is minimized to such an extent that it is entirely feasible, practical and economical to heat such cars Whenever temperature conditions, and the character of the cargo may require it. For example, if a railWay'oWns a thousand refrigerator cars the chances are that only a small proportion of these cars at any time Will be used under conditions making heating desirable. If it Were necessary to equip all of these cars with the ordinary heating systems the cost of installation might be ceived, to say nothing of the diminution in carrying capacity resulting from having steam coils permanently installed in each of said cars. By utilizing my invention a railroad company can equip each of its refrigerator cars with a train pipe, regulating devices and such piping as may be necessary to supply the heaters With steam from. the train'pipe and. carry off the Waterof condensation, and in addition to this equipment it may have on hand just enough of the removable radiating elements of my inventionordinarily a comparatively small 1111111 Wlll do-to meet the requirements for heat ing such cars at such times and forsuch periods as they may need to be heatech These heating elements, moreover, may be distributed at different points'on' the road as the traflic demands.
