UNITED STATES PATENT OFFICE.
EDWARD E. HARGREAVES, OF SARNIA, CANADA.
I IMPROVEMENT IN CAR HEATERS AND VENTILATORS.
Specification forming part of Letters Patent No. 174,523, dated March 7, 1876; application filed e. January 28, 1876. I
To all whom it may concern:
Be it known that I, EDWARD E. HAR- GREAVES, of Sarnia, in the county of Lambton and Province of Ontario, Canada, have invented an Improvement in Warming and Ventilating Passenger-Oars, of which the folger-car without the seats, portions of the walls being broken away to show the internal arrangement. Fig. 2 is a sectional bottom plan of the fan and pipes under the car. Fig. 3 is a cross-section of the heater, jacket, and freshair duct at one end of the car.
In the drawing, A represents the body of a passenger-car, beneath which is located an exhaust-fan, B, adapted to operate equally well when rotated in either direction, which fan is driven by a belt, 0, from a pulley on an adjacent axle. J) is the main suction-pipe of-the fan, from which two branch pipes,.D D, are led up through the floor of the car, the mouth of each terminating in a register, a, in the aisle of the car. These registers' are, respectively, located about one third the length of the car from the ends thereof. bis an in wardly-swinging valve, hung in an opening in the side of the suction-pipe D, and. may be actuated by a spindle extending up through the floor of the car, as shown. By opening this valve more or less the volume of air to be withdrawn from the car can be regulated as desired. The more the valve is opened the less rapidly will the fan exhaust the air from the car. At each end of the ear, in one corner thereof, there is placed a stove or other heater, E, surrounded by a jacket, F, to the lower part of which fresh air is supplied by a duct, 0, extending through the side of the car. Its outer end should be provided with a screen, to exclude dust and cinders. The fresh air as it enters the car will thus be warmed, and naturally will rise into the upper part of the car, whi e the colder air being heavier, and to a certain extent loaded with exhalations carrying carbonic acid, will naturally'settle near the fioor,'from which it will be drawn away by the exhaust-fan, which serves then not only ,to ventilate the car, but will" also equalize the temperature.
I do not wish to be confined to the use of a jacketed stove, as shown, as it is evident that any tubular or flue heater may be employed in lieu thereof for warming the influent aircurrents.
What I claim as my invention is The combination, with a railway passenger-car, of the following elements: openings EDWARD E. HARGREAVES.
