APPARATUS FOR HEATING CARS AND SIMILAR STRUCTURES.

SPECIFICATION forming part of Letters Patent No. 373,575, dated November 22, 1887.

Application led Octolr r 4, 1&7. Serial No. 251,435.

To @ZZ whom it may concern.-

Be it known that I, HENRY MASON YOUNG, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Apparat-us for Heating Cars and Similar Structures, of which the following is a specification.

This invention relates to apparatus for heating cars and similar structures; and it consists in the construction and arrangement or combination of parts hereinafter disclosed in the description, drawings, and claims.

The object of my invention is to provide an apparatus for heating cars and other similar structures, which is simple in construction, easily applied, readily operated, not liable to get out of order, and cheaply manufactured.

The invention may be employed in heating railroad cars or coaches, and under some circumstances in heating buildings; but it is more particularly applicable to the heating` of street-cars, and for the purpose of illustration I have shown it in the drawings as applied to the latter.

Figure 1 represents a cross-sectional view of the lower part of the body of a street car with my improved apparatus con nected thereto, Fig. 2, a sectional view of a portion of the car on the line x x of Fig. l; and Fig. 3, a detail plan view of the non-heat-conducting casing, showing the arrangement of the piping which may be used therein.

A A represent the sides, A the floor, and A* A5 the seats, of the car, constructed in the ordinary manner.

Beneath the floor A3, and extending across the full Width of the car, is secured a hot-air chamber or casing, B, the walls thereof being made double, so as to form a dead-air space, a, whereby the walls of said casing are rendered non-heat-conducting, so as to protect its contents from the cold air. i

Connected to and opening into the bottom of the hot-air casing B is a casing or shell, C, having its lower end open. Inside of this (No model.)

them from finding their way into the interior ofthe car. These casiugs or shells are so arranged with respect to each other as to leave an annular air-passage between them; also, the inner shell, D, is open interiorly from bottom to top, so as to atiord free circulation of air within the same, and thus supply the necessary amount of air to the burner. This construction of the inner shell I regard of special importance, inasmuch as a more copious supply of fresh air is required for gas or hydrocarbon burners than for stoves or grates burning wood, coal. and similar fuel; also, said inner shell contains a large interior surface, outside of which the intiowing air passes in entering the space between the same and the outer shell and becomes thoroughly or highly heated. \Vithin the inner shell, D, is Suspended a generator or heater, D, connected to piping E, which is arranged in coils within the casing B, as shown more plainly in Fig. 3.

The form of heater or generator which I prefer to employ in connection with the open shell D is shown in Fig. 1 ofthe drawings, and consists of two drums, D' D2, connected by a double conical drum, D3, and a series of tubes, F. The outlet and inlet ends of the piping E are respectively connected to the drums D D, so that a complete circulation of hot air is maintained between the piping and the generator.

The form of burner which I prefer to employ to impart the necessary heat to the gen-' erator is also shown in Fig. 1 of the drawings, and consists of a hydrocarbon or other nonsmoke-produeing burner, N, arranged beneath the generator D' and within the inner casing or shell, D. This generator and hydrocarbonburner I have made the subjects 0f applications for separate patents, led simultaneously herewith and respectively serially numbered 251,436 and 251,433, and therefore I do not claim them specifically in the present application.

Beneath the seats A4 A5 the floor A3 has openings, as shown at G G, to connect the spaces beneath the seats with the interior of the hot-air casing B, so that the heated air may freely pass from said casing into the interior of the car through the perforations c, formed in the fronts of the seats.

When the .air in the chamber B becomes heated by the radiation from the pipes E (if IOO they be used) and rises into'the spaces beneath the seats A4 A5, the cold air will at thev same time rush in between the shells C D and take its place, and, being in turn likewise I vent it from entering the car.

The upper portion of the inner shell, D, and other parts ofthe apparatus, if found necessary, will be protected by suitable nonheatconductors, so as to prevent them from igniting the wood-work ofthe car.

It is obvious that it is within lthe scope of my invention to employ the hot-air casing wlthout the piping therein. By dispensing` with said piping the weightof the car will be considerably lessened, which, of course, is desirable. Other obvious or minor mechanical changesin the construction and arrangement ofthe parts of my invention can be made without departing from the principle thereof.

Having thus fully described my invention, what I claim as new isl. In heating apparatus for cars and'similar structures, the combination of the hot air chamber having non-heat-conducting walls,and the lower partof a car provided with openings or connections between said hot-air chamber and its interior, with an outershell connecting the interiorof said chamber with the outer air, an inner shell which is open from bottom to top and placed within said outer shell, a heater orgenerator,and a burner arranged within said inner shell'and adapted to heat the air in its passage to said hot-air chamber, substantially as described.

2. In heating apparatus for cars and other structures, the combination of the hot air chamberhavingnon-heat-conductingwalls,and the lower part ofa car provided with openings or connections between said hot-air chamber and its interior, an outer shell connecting the interior of said chamber with the outer air, an inner shell, which is open from bottom to top and placed within said outer shell, a generator or heater and a burner arranged within said inner shell adapted to heat the air in its passage to said chamber, anda ilue connecting said inner shell with the outer air, substantially as and for the purpose described.

3. A street-car or similar structure having perforated seats AA5 and spaces or chambers beneath the same, in combination with the hotair chamber B, having non-heatconducting walls and attached to the .lower part of said car and communicating with the chambers beneath said seats, the outer shell, C, the inner open shell, D, smaller than and placed within said outer shell, and a generatoror heatenand a burner arranged within saidinne'rl shell and adapted to heat the air in its passage to said chamber, substantially as described.

4. In a heating apparatus for cars, the combination of the hot-air chamber B and the lower part of a car provided with openings between said hot-air chamber and its interior, with the heat-generator D, the burner N, and the piping E, coiled within said hot-air chamber and connected to said heat-generator, sub- Stantiallyv as and for the purpose described.

' 5. Inheating apparatus for cars and similar structures,the combination ofthe hot-air chamber B, having non-heatconducting walls, and

' the lower part cfa car provided with openings or connections between said hot-air chamber and its interior, with an outer shell,C.connect ing the interior ofsad chamber with the outer air, an inner shell, D, smaller than and placed within said outer shell, a heater, a generator,

and piping E, coiled within said hot-air charn- HENRY MASON YOUNG. Witnesses:
