'ro ALL wHoM iT 'MY eoNennN;

Be it known that I, Clin CARPENTER, ofthe city of Buffalo, in thc-county oi Erie, and State ot' New York, have invented certain new and useful Improvements in Apparatus for Heating4 Railroad-Cars; and I do hereby, declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making part of this specification, in which- Figure I is a plan and horizontalscction of a locomotive, tender, and one car, provided with my improved apparatus.

Figure II is a vertice.y longitudinal section of the tender and car, the locomotive being shown in elevation.

Lilie letters of reference designate like parts in both figures.

To avoid the use of stoves in the various cars forming a railroad-train, has lcd to the invention of a nuu1 ber of devices for heatngithe, cars-by means of hot-air or steam. The employment of steam is objectionable on account of the danger Lesulting from the escape of the steam in case of an accident breaking or-rupturing the pipes conducting it tothc diferent cars.

*F* VTheemploynzient of h'tb'air t'or warmingtho cars requires a fan or other blower to t'oree the airtli'rough `the conducting-pipes, which apparatus is operated by mechanism connecting` with the axle of the car when in motion. In case of a stoppage or detention of the train, by snow or other cause, some other means become necessary to maintain theproper temperature, as the air-forcing apparatus ceases to operate when the cars arc at rest.

My invention is designed to obviate these diiiicultios; and the invention consists- First, in the combination and arrangement'of an apparatus, by means of which either or both steam and hot air can be employed, the steam being used when the train is at rest, and when no danger need be apprehended from its employment. i

Second, in the arrangement and method of operating the fan-blower, which prevents the springing action of the body of the car from interrupting or deranging the motion of the fan, all ashereinafter fully set forth.

In the drawings, A is the locomotive, B the tender, and C a car coupled thereto. D is a stove or furnace arrangediu the tender for heating the air. E is a fan, of any suitable construction, for forcing the air through the heater and conducting-pipo. F-is the conducting-pipe, leading from the coil in the heater through the dfferent ears. g is n. triple-jointed coupling for said pipe, between the cars, although any suitable coupling that will yield with the relative movement of the cars may be employed. H represents one or more branch-pipes, leading from the main pipedown the side of the car, and terminating in a register or registers I,j being a valve for regulating the escape of the air from saidv pipe. .H, I,and j represent a corresponding pipe, register, and valve, for the steam when itis employed, the register or radiator I differing from I in being made tight, to prevent the escape of the steam into the car. K is a. steam-pipe, leading from the boiler and opening into the nozzle ot the air-pipe before it enters the heater, as shown. This pipe is provided with a suitable jointed or flexible coupling, g', between the locomotive and tender. A

The fan is operated by a belt, m, on a pulley, n, on one of the canaxles, connecting with a pulley, o, mounted in pendant-hearings from the body of the car. From this latter pulley a belt, p, extends upward through the bottom of the car, and around the pulley g onY tho fanshaft. A loosepulley, r, may also be employed on the fan-shaft, to which the belt p can be transferred in regulating the temperature et" the cars. By the use and arrangement of the two belts, m12, the operation of the fan is not affected by they springing or vertical movement-of the body of the car, as the fan-shaft and pulley o maintain an unvarying distance from each other, while the vertical motion oi the body of the car, to which the hearings of pulley o are attached, only nominally variesl the distance between the latter' and the ear-axle with which the belt m connects, so that the operation of the belt is not aiiected thereby. This arrangement, or somo equivalent means, is necessary, inorder to actuate the fan from the car-axle.

The operation of my improvements, thus constructed and arranged, is as follows:

When the train is in motion, the steam-pipe is closed, or nearly so, and the fan set in motion, which forces the air through the heater-conducting pipe and register into the dierent cors. A small amount of steam may be admitted into the air to render it properly moist, which makes it more agreeable to those inhnling it in the cars.'

In case of a detention of the cars from any cause, the air-pipe near the fan may be closed by n. vulve, s, und the air-pipes H by the valves j, while the vulve j being opened, steam is forced through tho coil in the heater and into the radiators I of the different cnrs, thus maintaining the proper temperature of' the Same.

Without some such provisionrextremo sulering would ensue in cases of long detention of the train by snow-tlrifts or other obstructions. It also becomes necessary in heating the cars a5 the dierent stations, before the train is put in motion.

By means'of my arrangement, the same conducting-pipe can be employed for both the steam and hot air; and th'e change from the use of the one to the other eiected in the simplest marmer. In hot weather, the fan and conducting-pipes can be employed in Ventilating the cars.

' I do not claim the employment of steam or hot air in heating rai1roadcors, nor an apparatus for the use of either alone.

What I claim as my invention, and `desire to secure by Letters Patent, is-

The combination und arrangement of the steam-pipe K, fan E, valve S, furnace D, conducting-pipe F,

branehes H H provided with vnlvesjj, and register and radiator I I', adapted for the use of steam und hot4 air alternately or together in heating a. train of cars, substantially in the manner s et forth.
