CAR HEATING AND VENTILATING SYSTEM.

SPECIFICATION forming part of Letters Patent No. 485,036, dated October 25, 1892.

Application filed February 24, 1892. Serial No, 422,629. (No model.)

To all whom it may concern:

Be it known that 1, JAMES A. HEALY, of Nashville, in the county of Davidson and State of Tennessee, have invented a new and Improved Car Heating and Ventilating System, of which the following is a full, clear, and exact description.

My invention relates to improvements in a system of heating and ventilating railwaycars; and its object is to provide a simple and efficient means of heating cars by steam taken from the boiler of the locomotive, to the end that no fire may be used around the car; to provide an efficient means of ventilating the car, and to attach the heating mechanism in such a way that each car will have a complete system of its own and that each' may be coupled in any part of the train and be thoroughly heated and ventilated.

To this end my invention consists in certain features of construction and combinations and arrangements of parts, which will be hereinafter described and claimed.

Reference is to be had to the accompanying drawing, forming a part of this specification, in which the figure represents a broken vertical longitudinal section of a car provided with my improved system.

The car 10 is of the usual kind and may be of any ordinary construction, and in one end of the car is a small room 11, having a window 12 therein, and this window opens into a small casing 13, in which is a coil of steam-pipe 14 and a rotary fan or blower 15 of the usual kind, the steam-coil being arranged between the window and the fan, so that the air entering the fan from the window will be first heated by passing over the steam-coil. The fan is driven by a belt 15"*, running over the fan-pulley and connecting with a grooved pulley 15 on the caraxle, the belt extending through suitable slots in the car-floor. A hot-air pipe 16 is connected with the fan or blower 15, and this pipe extends longitudinally of the car and between the car-floors, the pipe connecting near opposite ends of the car with registers 17, which open into the car, and through which the heat from the hot-air pipe passes. The main steam-pipe 18 extends longitudi nally through the car and in the upper part thereof, and if the car is provided with this system when it is built the steam-pipe may be hidden in the roof of the car, or otherwise it may be bronzed or ornamented, so that it will look well. The ends of the steam-pipe project through the ends of the car and terminate in flexible hose 19, each hose having at its free end a stop-cock 20, by means of which the hose and pipe may be closed, and the hose is adapted to couple with the hose of an adjacent car. The hose 19 should be arranged centrally in the car, so that it will be sure to come opposite to the hose of an opposing car, even though the cars might vary in width. A pipe 21, having a valve 21 therein, opens from the main steam-pipe 1S and con nects with the steam-coil 14, and the lower end of the coil terminates in a pipe 22, controlled by a valve 23, and the pipe 22 enters a common form of steam-trap 24, which has a suitable vent-pipe 25 opening from the pipe 22. Above the steam-trap is a valve-controlled pipe 26, and when live steam is used for heating the car the pipe 26 is closed and the steam allowed to enter'the trap 24; but when the car is heated by exhaust-steam the valve 23 is closed and the steam is blown off through the pipe 26.

Near the center of the car and opening through the roof is a common form of rotary ventilator 27.

The operation of the heating mechanism is as follows: The steam passes from the engine to the pipe 18 through any suitable coupling connection, and from the pipe 18 it passes through the steam coil 14:, and the air which enters the window 12 will be drawn through the coil by the fan or blower 15 and driven by the blower through the pipe 16 into the car. A continuous stream of pure warm air will be forced into the car and the foul air will pass out through the ventilator 27. It will be noticed that the air must constantly be supplied to the car while the car is in motion, as the blower will be continuously operated because of its connection with the caraxle. A hand attachment may be provided to work the fan when the car is not running.

I do not claim the detail construction of any of the mechanism shown in the drawing, and I do not claim, broadly, the mechanism for heating a car by steam taken from a locomotive-boiler.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- A car heating and ventilating apparatus 5 comprising a train-pipe for the steam, extending through the upper part of the car and having suitable couplings at its ends, a'chamher in one end of the car, into which abranch pipe leads from said train-pipe, a coil con- I0 nected to said branch pipe in front of the airinlet or Window of said chamber, two valved pipes leading from the coil through the bottom of the car and one of them provided with a steam-trap, and a blower in .said chamber operated from the car-axle and receiving the air after itpasses the coil and provided with a hot-air pipe discharging into the lower portion of the car, substantially as set forth.
