G. A. BARNARD. GAR HEATER.

UNITED STATES PATENT OFFICE.
GEORGE A. BARNARD, OF EAST ORANGE, NEWV JERSEY.
SPECIFICATION forming part of Letters Patent No. 429,183, dated June 3, 1890.
I Application filed November 14, 1887. Serial No. 255,054. (No model.)
To all whom it may concern:
Be it known that I, GEORGE A. BARNARD, of East Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Oar-Heaters, of which the following is afull, clear, and exact description, whereby any one skilled in the art can make and use the same.
The object of my invention is to provide an improvement in car-heating apparatus of the class that may be operated by steam furnished from the engine or other suitable source of supply outside the car, and that may also be operated in connection with the common coil-heater, in which a fire is built in a stove in the car.
To this end my improvement consists in the construction and combination of parts, as hereinafter described, and pointed out in the claims.
Referring to the drawings, Figure 1 is a diagrammatic View of the interior of a car illustrating the relative location and arrangement of the circulatory system of pipes and the heating device. Fig. 2 is a longitudinal sectional detail view, on an enlarged scale, of the steam-heater. Fig. 3 is a detail view, in cross-section, of the latter on the plane denoted by line a: w of Fig. 2.
In the accompanying drawings, the letter A denotes a railroad-car,apart of one end of which is shown in outline in Fig. 1 5 B, a heater of common and well-known form in car-heaters, with the coil 0 of pipes located within the heater in position to subject the water therein to the heat of a fire built in the fire-pit of the heater. The apparatus also includes the expansion-tank D, the hot-water-supply pipe fromthe coil 0 to the tank and from the tank D to the several radiator coils arranged throughout the car, and the return-pipe E from the said radiators to the coil.
All of the above features in a car-heating apparatus are old, and to such a system I connect what I term a steam-heater F, that is interposed between the heating-coil O and the expansion-tank D. This steam-heater consists of an apparatus in which a large steamheating surface is brought into contact with athin annular stratum of water, the steam heat being applied to both the interior and the exterior sides of the annular stratum of water in circulation. In its preferred form the steam-heater consists of the central steampipe g, leading from any suitable source of steam-supply, as the boiler of thelocomotive, this pipe being surrounded by another and larger pipe h, thus forming the annular chamber 71, that is closed against access of steam, but is connected at the lower end with the return-pipe E or an extension of the coil 0, and at the upper end with the pipe 11, leading to the expansion-tank. Inclosin g these two pipes is an outer wall or shell f, forming the outer steam-chamber, and communicating with a return-steam pipe f from this chamber f This shell is closed at its upper end above the top of pipes g and 72, and at its lower end has a flange f extending inwardly to the pipe g.
My improved steam-heater may be used in place of the coil-heater that requires a fire to be used in the car; or it may be used in connection with the ordinary coil-heater, that may be fired up for use on branch roads, the cars of which are not fitted with a steam-supply pipe, or for heating the cars in the shed or depot. The fire can there be dumped and the steam-heater utilized when the car is attached to a train piped for steam-heating. I11 order to provide for such an alternate use, the gate or valve 9 is provided in the sup ply-pipe g and the gate or valve f in the steam-return pipe f It is evident that the circular form in cross-section of the several pipes or cylinders making up the steam-heater, as shown in the drawings, is not material to my invention, and it is not limited thereto.
The steam-heater may be placed upright within the car in a corner in convenient position for connecting to it the pipes of the carheating system.
I am aware that I am not the first to invent, broadly, the combination, with a car, of a system of circulating-pipes within said car, and two heaters, both in operative contact with said circulating system, or with branches thereof, and adapted to be operated simultaneously or separately for imparting heat thereto.
I claim as my improvement- 1. In a car-heater, the combination,with the steam-pipe g, of the pipe 72, slightly larger than and surrounding the pipe g, and the outer shell f, surrounding pipe 71, said shell being closed at its upper end, and atits lower end having a flange extending inwardly to the pipe g, and suitable valved pipes for the circulation of steam and Water, substantially,
2. In a ear-heater, the combination of the steam-pipe g, with the pipe 71 surrounding it and forming chamber 71 and shell f, surrounding pipe 71 and forming chamber f", the said shell being closed at the top, and the two chambers being closed at the bottom at f,
