RAILWAYeCAR H EATER.

SPECIFICATION forming part of Letters Patent 1\l'o.373,626I dated November 22, 1887.

Application filed March 30, 1857. Serial No. 233,002. (No model.)

To all whom il? may concern.-

Beit known that I, Winsen W. WHITCOMB, a citizen of the United States, residing at Batavia, in the county of Genesee and State of New York, have invented a new and useful Improvement in Railway-Car Heaters, ofwhieh the following is a specification.

My invention relates to an improvement in railway-car heaters; and it consists inthe peculiar construction and combination Y of devices, that will be more fully set forth hereinafter, and particularly pointed ont in the claims.

In the drawings, Figure l is a vertical sectional view of a ear-heater embodying myimprovements. Fig. 2 is a horizontal sectional view of the same, taken on the line moc of Fig. l.

A represents a case, which is made of sheet or plate metal and is of suitable size and shape. The side walls of this case are vertical. At a suitable distance from the upper end of the ease is a horizontal diaphragm or plate, B, which forms the hotair chamber O in the upper side ofthe case, and at a suitable distance below the diaphragm B is a similar diaphragm, D, which forms a hot-water chainber below the hot-air chamber. The lower portion of the case forms a chamber, F, for cold water. At asuitable distance from the bottom of the case its side walls are provided on opposite sides with horizontal series of aligned openings G.

H represents a tray, in which is located a series of lamps, I. rlhis tray is provided on opposite sides with projecting danges or ledges K, which bear against the inner sides ot' the case. The tray has a series ot' pcrforations, L, in its lower sides.

The ease is located in one corner ofthe car and is rigidly secured in position. To the end of the car adjoining` the case is rigidly attached a pair of bars, M, which are arranged on opposite sides of the case. To these bars are pivoted a series of dogs, M', which project inward through the openings G and bear under the flanges K of the lamp-tray, thus serving to support t-he latter in an elevated position in the ease, with the bottom of the lamp-tray at a slight distance above the level of the water in the chamber F. These dogs are diamond or lozenge shaped and havetheir inner ends truncated. The combustion-chamber in the rase in which the lamp-tray is located is provided with a series of escape-openings, G', which communicate with vertical fines or pipes R, that lead to a central flue or pipe, S, which extends upward through the root` of the ear and serves to permit the escape of gases, soot, smoke, land other products of combustion.

T represents a series of pipes which are arranged in the bottom of the car and extend nnder the seats. These pipes communicate with the hot-water chamber E in the heater.

The operation of my invention is as follows: The water in the chamber E is heated by the lamps when the latter arelighted, and is caused to circulate through the pipes T, and thereby heat the interior of the ear. Air which enters the chamber O through suitable openings, C', in the sides of the said chamber becomes heated and is expanded and radiated through the car, thus assisting` in warming the latter. In the event of a collision or other railway accident, when the end ot' the car in which the heater is located is smashed in, the bars M, which are rigidly attached to the end Of th-e car. are moved longitudinally, thereby causing the dogs M to be drawn out through the openings G in the case and release their hold on the under side of the fianges K, thus causing the lamp-tray to be dropped into the cold water in the chamberFin the base of the case, and the lamps are immediately extinguished thereby, thus preventing the car from catching tire.

Having thus described my invention, I claim- 1. In a car-heater, the combination of the case A, having the cold-water chamber in its lower side, the lamp-tray or tire-pot, the dogs M', extending through the sides of the case and supporting the lamp-tray or tire-pot above the water-chamber, and the bars M, secured directly to the side of the car and connected to the dogs to draw out the latter when the car is smashed in, and thereby drop the iirepot or lamp-tray into the water'ohamber, for the purpose set forth, substantially as described.
