CAR HEATING AND VENTILATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 419,456, dated. January 14, 1890.

Application filed March 2, 1889. Serial No. 801.748. (No model.)

To aZZ whom it may concern.-

Be it known that 1, CHARLES A. KIMPTON, of Malden, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Car Heating and Ventilating Apparatus, of which the following is aspecification.

It is the object of my invention to provide improved means whereby fresh air, either heated or at its natural temperature, may be supplied to the interior of a car or train of pipe or pipes containing heated air, and

valves for controlling the amount of air passing or that may be passed through said pipes.

Of the accompanying drawings, forminga part of this specification, Figure 1 represents a side elevation (parts being represented as broken away and parts shown in section) of a car equipped with my invention. Fig. 2 represents'a partial longitudinal section of a passenger-car fitted with pipes to receive air from the car shown in Fig. 1. Fig. 3 represents a section on line so 00, Fig. 2. Fig. 4 representsa partial longitudinal section of a passenger-car, showing a modification of the arrangement of the air-circulating pipes. Fig. 5 represents a section 011 line so 0;, Fig. 4.

a designates a car, through which, near the roof, pass two pipes b c, the former communicating with the heater and steam-generator (1 through the medium of a connecting-pipe c, and with the pipe 0 through the medium of pipes f f and g, which are connected with the blower h.

1 and 2 designate valves in pipe I).

4 and 5 designate valves in pipe 0.

3 and 6 designate valves in pipe f, and 7 designates a valve in a pipe g which connects pipes f and f with pipe 0.

When the car is moved in the direction of the arrow marked on the drawings, and it is desired to convey warm or heated air into a car or cars in the rear, valve 1 will be opened and valve 2 closed, so that the air entering pipe b will pass through connecting-pipe e to the heater (1, and through the coils '6 in the heater, where it will be heated. Valves 3 and 5 will be opened and valves 7, 4, and 6 closed, so that the air from the heatermay be'drawn by the blower h through pipes f f and forcedthrough pipe 9 out through the rear end of pipe 0. Should it be desired to shut off the warm or heated air and convey cold or cool air only to the carsin the rear, valve 3 will be closed and valve 7 opened, when the air will be drawn by the blower through pipes c and f and forced out as before.

When the car is moved in a direction opposite to that indicated by the arrow, and it is desired to convey air through and discharge it from the pipes in a direction opposite to that before described, if warm or heated air only is to be used, valves 1, 5, 6, and 7 will be closed and valves 2, 3, and 4 will be opened, when the blower It will draw air in through pipe I), connecting-pipe e, the coil v. in the heater, and through pipes f f, and force it out through pipes g and 0. Should it be desired to shut off the warm or heated air under the last-mentioned conditions and employ cold or cool air alone, valve 3 will be closed and valve 6 opened, when the air will be drawn in through pipes c, f, and f, passing valve 6 and be forced out through pipes g and c, as before.

If it is desired to regulate the temperature of the air supplied to the cars by mingling cool air with the air which passes through the heater when the train is moving in the direction indicated by the arrow, the Valve 7 is opened to any desired extent, the valves 4 and 6 remaining closed, as before. A supply of cool air from the pipe 0 is thus admitted to the pipe f and passes with the warm air from the heat-er through the blower to the cars. \Vhen the train is moving in the opposite direction, the same result may be produced by closing the valve '7 and opcnin the valve 6. It will be SGQll,i)l101CfOl0, thatfresh air may be supplied to the ears either at its natural temperature or raised to any desired higher" temperature within the capacity of the heater, so that the cars are thoroughly ventilated and may be easily kept at the desired temperature. The air thus supplied maybe distributed through the passengercars by main pipes 1), extending lengthwise of the cars and communicating through suitable couplings c with the pipe r, said pipes having suitable outlets or branchespflthrough which the air is discharged at numerous points into the car. (See Figs. 2 and Each of the branches 1) is preferably pro vided with a valve 1', whereby the air may be shut off, if desired, so that each passenger may control the admission of air to his or her immediate vicinity.

If preferred, the longitudinal pipe 2) may be arranged on the floor of the car with its branches 1) under the seats, as shown in Figs. 4 and 5, in which case two pipes 17 should be en1ployedone at each side of the aisle.

Provision is made in the heater (Z for generating steam, which is conveyed through the medium of pipe j to the engine 7,:, from which, through the medium of belts and pulley the blower his operated, as may also be a d ynamoelcctric machine Z, by which electricity may be generated for the purpose of lighting the cars.

It is to be observed that the valves of the several pipes may be so adjusted as that the heated and cool air may be forced through the pipes at the same time, and in any desired proportion with respect to each other.

The contrivanee is simple in organization and may be constructed and operated at comparatively low cost.

It is obvious thatchanges may be made in the form and arrangement of parts without departing from the nature or spirit of the invention.

I claim- 1. In a car heating and ventilating apparatus, the combination of a car, a heater, and a blower therein, a system of pipes or conduits whereby external air is conducted through the heater to the blower and from the latter to a succeeding car, said system including a.

pipe to receive external air and conduct it to the heater, and a pipe 0, which extends through the car and is adapted to be opened to the external air at either end of the car, so as to introduce cold air or air at its natural temperature from either end of the car into the heated air in said pipes, and means for controlling or regulating the quantity of cold air thus admitted, as set forth.

2. In a car heating and 'entilating appara tus, the combination of a car, a heating apparatus, and a blower or air-forcing apparatus in said car, means for admit-ting fresh external air to the heater, a conduit for the heated air from the heater to the blower, an air-pipe extending into the car from opposite ends thereof, a connection between said pipe and the blower, valves in said pipe at opposite sides of said connection, whereby either end of said pipe may be made the receiving end and the other the discharging end, and independen t valved connections between said pipe and the hot-air conduit, at opposite sides of the said blower-connection, whereby either end of the air-pipe may be connected with said conduit to supply fresh air thereto, as set forth.
