UNITED STATES PATENT OEI-ICEo WILLIAM FLANAGAN, OF CHICAGO, ILLINOIS.

APPARATUS FOR HEATING RAILWAY-CARS.

SPECIFICATION lforming part of Letters Patent No. 375,738, dated January 3, 18L`8,

Application filed August S, 1884. Seria! Nod-10,042. (No model.)

To aZZ whom, it may concern:

Be it known that I, WILLIAM FLANAGAN, a citizen of the United States of America, residing in Chicago, county of Cook, and State of Illinois, have invented new and useful Improvements in aHeating Apparatus for Street- Railway Cars, of which the following is a specification.

This invention relates to certain improvements in heating street-cars; and it has for its objects to provide heating devices for the same which will not interfere with the interior of the car, which will supply heated air uniformly throughout the same, and which can be readily controlled and managed, as more fully hereinafter specified.

The above-mentioned objects I attain by the means illustrated in the accompanying drawings, in which- Figure l represents alongitudinal sectional View of a street-car, showing my invention applied thereto. Fig. 2 represents partly a top view and partly a horizontal section of a portion of the car and heating devices; Fig. 3, a transverse vertical section of the car,showing the heating devices; Figs. tand 5, sec tions on an enlarged scale of the heating devices; Fig. 6, a top view of one of the side compartments in which the heating devices are located. Fig. 7 represents a side elevation of the heating-chamber detached. Fig. 8 represents a longitudinal section of a car with a portion broken away, showing a modification of my invention, with' solid fuel as ernployed for heating; Fig. 9 is partlyatop view and partly a longitudinal horizontal section Aof a portion of a car, showing a modification of the heating medium; Fig. 10, a cross-section of the car and heating devices, with the modified form of heater, and Fig. 11 an enlarged cross-section of the modified form of heating devices.

Referring to the drawings, the letter A indicates the seat-supports, which are constructed of metal, each having a fiat bottom and an in clined side provided with apertures a and a, for the emission of hot air to the interior of the car. The said supports extend longitudinally from end to end of the car, and are seated in longitudinal Hoor-openings at each side of the bottom of the car. Upon the upper edges Achamber Cfor combustion.

of the said supports rest the seats F, which may be of the ordinary or any approved construction.

' Below the car-licor, at each side, are secured the metallic easings G, which extend longitudinally between the wheels, being :flanged at their upper edges and bolted or otherwise secured to the bottom plate of the seat-supports.

The casings G are provided with bottom openings, e, Figs. land 8, at each end, for the admission of the air to beheated into the heating-spaces q, and for this purpose these inletopenings are provided with deiiectors f, depending from the bottom at each end of said easing, so as to catch the air as the car is moving and direct it upward through said opening into the heating-spaces q. These openings and detlectors are provided at each end of the heatproducing chamber, soas to act with the car running either end foremost. The heatingspaces q are formed within the casing and eX- tend all around the heating-drum B, and open into the seat-space I by the perforations c in the bottom of said seat-support, as shown in Fig. 4. The easing is provided with longitudinal ribs lr, Figs. 4aud1l, to strengthen it, and with a suitable door, so that access may be had to the interior and to supply air to Vithin the upper part of the casing is secured a longitudinal chamber, B, which is oval in cross-section, and connects with the re chamber C by means of a series of tubes, b, which extend to a horizontal partition-plate, d.

The chamber B at itsupper part, near each end, has connected to it the air-pipesp p', Fig. 7, which extend to neareach end of the car, and are bent backward and carried out through the door of the car over the wheels, as shown x in Fig. l of the drawings.

The tire-chamber is preferably heated by a lamp, D, having numerous burners; but in stead of such lamp the chamber may be provided with a grate and ash-pit, as shown in Figs. 810, and 11, so that solid fuel may be employed, the casing in this instance being provided with an inclined door for the insertion of the fuel.

The operation of my inventionis as follows: Heat being applied in the chamber C, either by the lamp D or furnace D', a current of hot IOO air is established through openings e e', Figs. l and 8, into and through the air-spaces q, and into the car through the seat-openings a c. rlhe heated products of combustion pass into the chamber B and out through the pipes p p', thus effectual] y heating the car.

The heating devices are removable, so that they may be taken out in Warm weather, the apertures in the door and seat-supports in this instance serving for the admission of fresh air to ventilate the car.

Referring to Fig. 7, the pipes for the'escape ofthe products of combustion are seen as connected Withand extending from each end of the heating-drum B under the-seat and returning upon itself within the seat-space, and passes down through the floor of the car for the escape of the products of combustion and for the necessary draft for the chamber of the heating device, so that the escaping heat is utilized to heat the incoming air beneath the seats. The heating-drum B is supported within the heating-chamber by the tine-pipes so that the air to be heated is brought in contact with the outer Wall of the heatingdrum as it passes through the air -heating spaces to the outlet-openings. The escapepipes are arranged, as described, to adapt them to cars ruiming either end foremost and to correspond with the air-inlet openings.

I claim- 1. In a car-warming apparatus, the combination of the seat-support having bottom and side perforations, at a, with the casing G, forming an airheating chamber open to the outer air, communicating with said bottom opening, the heating-drum B, located Within said chamber, having suitable escape-pipes, the chamber C, containing a heat-producing device, the partition d, dividing thesaid chambers, and the Hue-pipes b, connecting the interior ofthe heating-drum with the chamber containing the heat-produring device, substantially as described.

2. In a car-Warming apparatus, the combination, with seat supports having bottom and side perforations, a' a, of a casing, G, divided by a horizontal partition, d, to form a lower chamber for containing a heating device andan upper chamber forheating air, and

a heating-drum arranged within the upper chamber, supported by the partition fine-pipes b, and having suitable escape-pipes arranged within the seat-supports and opening beneath the car-floor, the said air-heating chamberhaving suitable air -inlets, substantially as described.

3. In a warming apparatus for street-cars, the heatingdrum B, having an escape-pipe at each end, a heating device therefor, and a divided metal inciosing-case for these parts, forming alower chamber for the heating device and forming an upper chamber surrounding theheating-drum, open at each end at e, in combination with iron seat-supports having the perforations cz a', the said iron seat-supports being fitted in Hoor-openings of the car and forming the tops of the air-heating chambers, and the said escape-pipes coiled Within the seat-supports, substantially as described.

et. The heating apparatusconsisting of the iianged casing G, having interior horizontal ledges or ribsk, the heating-drum forming the ehambenB, mounted upon a plate, d, seated upon said ledges, and a bottom heating-lamp,

said casing G constituting a removable closure for said heating devices, in combination with metallic car seat supports having a perforated bottom forming a cover for the top of said casing G, and the pipes p p', for the escape of the products of combustion, arranged Within the said seat-supports and terminating beneath the car-Hoor, substantially as described.

5. rllhe imp roved car-heater herein described, consisting of the oblong casing G, having a top air-heating chamber or spaces, g, opening at each end at e e in the bottom of said casing, each opening e having a detlector, f, the heating drum B, its flue-tubes b and plate cl, and the heatinglamp D, in combination With the perforated metallic seatsupports forming the top of said casing, and the pipespp, connecting each end of said heating-drum B Within the seat-supports and terminating at the bottoni of said ear, all as shown and described.

VILLAM FLANAGAN.
