EIIIRAIM HAMBUJER, OF DETROIT, MICHIGAN.

CAR-HEATER.

SPECIFICATION forming part of Letters Patent No. 353.558, dated November 30, 1886.

A pplieation tiled April 12, 1886.

To aZZ whom it may concern:

Be it known that l, Eri-IRAM HAMBUJER, of Detroit, in the county of Vayne and State of Michigan, haveinvented newand useful lm- 5 provements in Car-Heaters; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to certain new and useful improvements in heating furnaces, especially designed for heating street or tramway cars where the room is limited, and which may be used-without interfering with the seating capacity of the ears.

zo while the grate, ash-pit section, and ash-drawer project downward through the door, so that the dust arising from clearing the grate and ash pit is kept from theinterior of the ear. Means are also provided whereby, if the heater is situated midway between the two ends of the car,

the smoke or exit pipe may be carried in both directions under the seat,and through the end walls of the car, and then up through the roof which covers the platforms, so that the driver 3o at one end and the conductor at the other may receive some benefit from the fire.

The invention consists in the pecular construction of the parts, their location with relation to each other, and their combination, as

more fully hereinafter described.

Figurel is a front elevation of my improved heater. Fig. 2 is a vertical longitudinal section, looking toward the rear of the heater. Fig. 3 is a vertical central cross-section from Fig. 4 is a horizontal section through thesmoke-jacket. Fig. 5 is a plan of the smoke-jacket, outer case, and feed-doors.

In the accompanying drawings,whieh form a part of this specitication,A represents the baseplate of the heater, which is formed with a well, as shown, and from which is pendent the ash-pit and draft-section B,designed to project through the floor C ofa car,while the baseplate is provided with suitable feet, a, which 5o rest upon the floor.

Serial No. 108,620.

(No modrlJ,

D represents the tire pot,whicl1 is supported by the base A, and below which is located a grate, E. This grate is pivotally set in a bracket, F, which latter is pivoted to a stud projecting from the wall of thcash-pit section, its opposite end being supported by a dog, G. \Vhen it is desired to dump the grate, the free end ofthe dog is pushed inwardly, freeing the end of the bracket from the head ofthe dog, allowing bracket and grate to swing downwardly and deposit the contents of the fire-pot into the ash-pit, from whence they vmay be readily removed through the door H.

The fire-pot is east or formed domeshaped,

and is provided with a feed-door, I, surrounding the ends and back ofthe ire-pot,and supported thereby is a jacket, J, into which the products of combustion pass'from the tire-pot through au opening formed in the sides thereof, as at b. These openings have secured over them fingers K, which may be east,if found preferable, as an integral part of the lire-pot, and they are for the purpose merely of preventing the fuel or contents of the lire-pot from falling into the chamberL,wl1ich is formed by the jacket .I aroundthe tire-pot, and either one of these openings, as may be desired, or as ina'y be necessary from the position that the stove -inay occupy within the car, should be closed by a plate, N, theproduets of combustion passwhence they find an exit at either end of the jacket at M, or through a verti cal pipe connected at M, as may be desired. This plate N is retained in position by means ofa bolt,d,whieh projects outwardly between the fingers K of the tire-pot, and receives upon its outer end a nut, e, that will not slip between said fingers, the said plate being ot' sufiicientsize and shape to fully close the draft-opening at that point. For instance, if it is desired to have 'the products of combustion pass out upon the righthand exit, as in Fig. 4, there is a cap placed over the other exits, M M,and the right-hand exit of the iire-pot is likewise closed, thereby forcing the products of combustion to pass to the left (referring to Fig. 4) into thejacket J, thence around the fire-pot and out at the righthand end of thejacket, as is clearly shown by the arrows in the figure referred to, thereby IOO ' radiating their heat through such jacket into the car.

O is an external casing, that is preferably perforated at its sides and front, While its top is imperl'orate. It forms an air-space, O', surrounding the smoke-jacket .I.`

It will be seen upon referring to Figs. 2 and 3 that the heated air thrown off from the iirepot and the jacket surrounding it will heat the air and caus a circulation of air through the outer space, O', as is clearly shown in Figs. 2 and 3, already mentioned. Of course, if desired,'both ofthe openings at the ends ofthe ire-pot'nnay be left open` particularly when a draft in a directline, as through M, is necessitated by the position that the 4stove or heater may occupy in the cur. j

The case O is provided with a door, as P, which it is necessary in the construction shown to open before fuel can be introduced into the iire-pot. It is evident, however, that a door of the construction shown or any other door or .slide may be employed, as the mere function of the door is to provide acommunication through the perforated case Which surrounds thestove to the feed-door, and to serve as a shield or guard to prevent the clothes of any person occupying a seat'immediately above coming in contact with such portions of the stove as may be suiiieiently heated to burn or Scorch them, While at the same time it gives a more ornamental finish to the structure. The space .0 between the re-pot and the feeddoor P is preferably separated by suitable partitions from the space O'.

In practice, the device being placed in a car and arranged substantially as shown and described, a fire is made in the {ire-pot, either as such cars are usually constructed there will be leakage enough to insure a rapid change of inconveniently so, owing to the air-space.

Il` desired, and it Would be preferable, the side of the car and'under side of the seat may be covered with sheet-iron, so as to prevent the radiation of too much heat to the seat immediately above.

. What I claim as my invention is.n

l. The combination, with the fire-pot provided with openings b, of the fingers K, secured over said openings, and the plate N, pivotally secured to one of said iingers, lsubstantially as and for the purpose specitled.

2f. ,In acar-heater, the combinationvith the fire-pot, of the jacket J, surrounding the same and forming the chamber L, the fire-pot being formed with openings affording communication with said chamber, plates for controlling said openings, and one or more exitsV from said chamber through the said jacket, substantially as described. f

3. In a car-heatelg'the combination of the fire-pot, the jacket J, surrounding the same and formed with exits M M. and exit M at Vvice may be somewhat Warm, it will not be right angles thereto, removable caps for said Y exits, and the external casing, O, forming an air-space around thejacket J, substantially as described.

4. In a car-heater, the combination `of the repot, the jacket J, surrounding the saine and provided with exits M M M', as described, and removable caps'therefor, the perforated external casing, O, provided with feed-door P, and suitable partitions forming the feed-throat bet-Ween the tire-pot and the feed-door,and the pivoted plates N, substantially as described.
