DAVID GONNELL, OF WILMINGTON, DELAWARE.

CAR-HEATER.

SPECIFICATION forming part of Letters Patent No. 379,101, dated March 6, 1888.

Application filed March 14,1887. Serial No. 230,750. (No model.)

To all whom it may concern:

Be it known that 1, DAVID CONNELL, a citizen of the United States, residing in Wilmington, Delaware, have invented certain Improvements in Oar-Heaters, of which the following is a specification.

My invention consists of a railroad-ear heater designed to permit the heating of the car either.

by steam derived from a sourceoutside of the car or by direct radiation from a stove Within the car, the latter being protected from injury in case of accident.

In the accompanying drawings, Figure 1 is a front view ofa car'heater constructed in accordance with my invention; Fig. 2, a longitudinal section of the same; Fig. 3, asectional plan view on the line 1 2, Fig. 2; and Figs. 4 and 5, respectively, a perspective view and a section of the device for fastening the doors of the combustion-chamber and ash-pit 0f the stove.

Theuseof coal-stoves as a means of heating railway-cars is deservedly regarded with disfavor on account of the almost inevitable ignition of the wreck when a car containing such a stove meets with an accident whereby the end containing the stove is smashed or the car is overturned.

Radiators using steam orhot water have been proposed as substitutes for the stove; but the use of a radiator alone is attended with certain objections which have deterred railroad managers from adopting it as a heating device. I therefore in my heater combine both the stove and the radiator, the latter being supplied with steam from a source outside of the car-from the locomotive,-for instanceand the stove being surrounded and protected by the radiator.

As shown in the drawings, A represents the casing of the stove, which in the present instance is cylindrical aud is made of strong sheet metal, with flanged heads at opposite ends of the cylinder, so as to possess considerable inherent strength, the cylinder being provided with projecting casings Band D, which serve to afford communication respectively with the combustion-chamber and ash-pit of the stove and are provided with suitable doors at their outer ends.

The ring a,which supports the fire-pot lining b of the stove, has inwardly-projecting lugs d,

which engage with a flange at the upper end of the grate F, the latter being in the form of a basket projecting down into the ash-pit, and slotted so as to provide for the poking or agitation of the fire by a suitable implement.

Surrounding and inclosing the stove is a radiator structure, which consists of circulatingpipesf, secured to a hollow base, G, which is mounted upon a slotted casing, H, the latter resting upon the base-plate I on the floor ofthe car.

The radiator structure and the stove are firmly confined between this base-plate I and a top plate, J, by means of bolts 9, provided with suitable nuts, whereby the top and base plates are confined together, and other bolts,h, pass from the top plate down through the base plate and through the frame-work of the carbottom, so as to securely retain the heating structure in its proper position in the car.

In the event of a collision the strong radiator structure surrounding the stove-casing and extending down to the bottom of the firepot serves as a shield or guard for the stove and prevent-s it from being smashed, so that even if the stove contains a fire there is small likelihood of the hot coals escaping therefrom,

In order to prevent the coals from escaping in the event of the overturning of the car, I provide a valve, 1 for closing the mouth of the pipe k, through which the products of combustion escape when the stove is in operation,this valve being of any material possessing sufli cient strength and having the property of re sisting the action of the heat.

In the present instance the valve is in the form of a ball, and the lower end of the pipe is bell-mouthed to provide aseat for the same, the valve under ordinary circumstances being contained in acage, 1', depending from the top of the stove. To prevent the escape of hot coals or ashes through the feed or ash-pitcasings D, the catches which retain the doors of the latter are perforated for the reception of a retaining-hook, m, as shown in Figs. 4 and 5, so that the accidental opening of either of the doors is practically impossible.

The ash-pit casing D is perforated, as shown in Fig. 2, in order to supply to the ash-pit sufficient air to support combustion, the openings not being large enough, however, to permit the escape of particles of fuel of such size as to be dangerous.

I am aware that water-heaters for cars have been combined with stoves, and that the waterehamber has been constructed to envelop a portion of the stove-casing, but such devices lack the strength of the tube-radiator structure, and do not completely iuelose the stove. Moreover, the stove is the sole source of heat, so that fire must be maintained constantly in the same, thus defeating the main objectof my invention.

I therefore claim as my inventiou 1. The combination, in a railroad-car heater, of a stove having grate, fire-pot, and ash-pit, and a casing having air-inlets to said fire-pot and ash-pit and an outlet for the products of combustion, and a tube-radiator structure independeutof the stoveand having connections 2o with an outside generator, said structure in to this specification in the presence of two sub- 35 scribing witnesses.
