JOSEPH A. LONG, OF BROOKLYN, NEW YORK, ASSIGNOR TO AARON I-I. EASTMOND, OF SAME PLACE.

HEATING AND VENTlLATlNG APPARATUS FOR STREET-RAILWAY CARS.

'D SPECIFICATION forming part of Letters Patent No. 511,961, dated January 2, 1894.

Application filed September 29, 1893. Serial No. 486,775. (No model.) t

To all whom it may concern:

Be it known that I, JOSEPH A. LONG, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented an Improvement in Heating and Ventilating Apparatus for Street- Railway Cars, of which the following is a speciiication.

Difficulty has heretofore been experienced in applying a heater to a street railway car in such a manner as not to interfere with the seating capacity of the car, and usually difficulty is experienced in warming the ends of the car and in producing a sufficient circulation of atmosphere through the car for the purposes of ventilation.

My improved heater is made with reference to occupying but a small space Within the car and to the introduction of fresh air in a warm condition for the purposes of ventilation. I suspend below the door of the car a fire-pot and ash-pit and surround the tire-pot with a guard through which air is admitted to pass up into a chamber around the iire donne, and a double asbestus-lined casing is provided to form an air chamber within which air is heated and passed by conduits toward the respective ends of the car, and the entire heater is beneath the seat and in such a position that it does not interfere with the seat being occupied by passengers.

In the drawings, Figure lis a sectional plan at the line ne, of Fig. 2. Fig. 2 is a vertical section at the line y, y, of Fig. 1. Fig. 3 is a vertical section at the line z, z, of Fig. 1.

In the door A of the car and below the seat B an opening is provided adapted to receive the casting C that is in the form of a frame, and this is supported by hangers D that rest upon the surface of the iioor and pass in below the frame C and are bolted thereto so as to support this frame C reliably from the floor of the car.

The ash-pit E is preferably made of a castwardly projecting fianges to fit upon the top of the ash-pit E, and upon this ring F there is a fire-pot L, and the grate G rests upon a bearer or cross bar H that has an opening for the reception of the central pivot '7 of the grate, and the grate is adapted to receive a lever handle by which the grate can be shaken when the door 5 is opened.

There are bolts lpassing down through the frame O, the ash-pit ring F and to the ashpit E, so as to connect the parts firmly together and suspend them from the frame C; and it is advantageous also to have theheads of the bolts l above the lugs at the base of the fire dome K so as to bind together the ash-ring, the lire-pot, the frame and the iire dome, and to allow for these parts being easily separated for repairs whenever necessary.

At one side of the lire dome K is a fuel hop per M, the outer end of which is closed by a door N supported by a frame O, andthe door N is preferably provided with an inner lining 10 with asbestus between the lining and the door so as to prevent thedoor or the frame O being heated, and this door is sufficiently above the floor A of the car to be accessible from inside the car for supplying the fuel to the ire that rests upon the grate G and is Within the fire-pot L. p

From the top of the fire dome K a pipe P passes oft to convey the products of combustion; it may be inclined backwardly and pass up through a suitable non-conducting inclosure on the inner side of the car between one window -and thenext, or such pipe may pass off, as indicated by the dotted lines P', to one or both ends of the car and enter a vertical pipe for the discharge of the products of cornbustion, such pipe in either instance passing through the roof of the car for said gases to escape to the external atmosphere.

Around the fire-potL and between the same and the frarne C is a guard Q, preferably in the form of a conical ring having openings at the opposite sides thereof toward the front and back ends of the car for air to pass into this guard and rise up through the openings l1 in the frame C, and above the frame C is an exterior casingR and an interior casing S. These casings are preferably of sheet metal and the exterior casing R is lined with asbes-4 IOO tus-paper or similar material at 12 so as to eectually prevent the warmth passing out directly from the ire dome into the car, and the interior casing S does not extend up to the top of the casing R but terminates near the level of the top of the fire dome K, there being openings 16 through the interior casing for the free passage of air from the space between the exterior and interior casings into the chamber which receives the heat from the tire dome; and I remark that the lower edges of the casings R and S are received into grooves or against anges upon the upper surface of the frame C, and there are openings at 13 that allow the external atmosphere to pass up between the casings R and S and through the openings at the top of the casing S into the air chamber where the air is heated from the fire dome K.

It will b e observed that the exterior casing R is adapted to set beneath the seat Bin the car with a free air space between the top of the casing and the under sideot' the seat, and in consequence of the lining of asbestus at l2, the heat is not communicated to the seat, and this casing R is held between the frame O and the ilue hopper M and the parts are properly connected by suitable bolts and but little heat is conducted to the frame O or to the door N in consequence of the non-conducting material or lining 12 of the casing, and the lining of non-conducting material 10 for the door N.

In street cars it is usual to provide panels or other inclosures below the front edge of the seat and between the same and the floor. I avail of this space beneath the seat for the introduction of air pipes T which extend out laterally from the casingR in both directions and either open into the air space under the seat near the ends of the car or else open through registers or other suitable openings in the panels or inclosures under the seat, so that the hot air is conveyed to the ends of the car as these portions are always the most difficult to heat, and the constant inflow of fresh air ventilates the car. thoroughly by constantly changing the air inclosed within the car. It will now be observed that when the car is in motion the atmosphere will pass through the openings in the conical guard Q and up through the openings l1 into .the air chamber around the ire dome K and that air will also pass upv through the openings 13 into the chamber between the exterior casing R and the interior casing S, so that the air will receive the radiated and conducted heat from the iire within the fire-pot and dome, and that the hot air will pass from the casing through the air pipes T and discharge into the car; and a suitable damper may be provided in the smoke-pipe for regulating the'draft and varying the consumption of fuel so as to regulate the temperature of the air passing into the car and thereby maintain the proper heat of the car and ventilate the same by the introduction of the fresh air.

I do not claim a heater within a street car placed below the seat or in an opening provided in the seat at one side of the car.

I claim as my invention- 1. The frame C supported from the licor of the car and having openings therein, the iirepot and guard below the frame, the ash-pit and its ring below the fire-pot and bolts passing th rough the respective parts and by which they are suspended from the frame, a ire dome above the frame having a fuel hopper at one side, a casing surrounding the ire dome, and a door having an opening throughV the casing to the fuel hopper, and lateral air discharge pipes passing beneath the seat, substantially as set forth.

2. The combination in aheater for street cars, of an ash-pit, its ring and grate, a firepot above the ring, a guard surrounding the lire-pot and having openings toward the front and rear of the car, a frame with openings, means for supporting the same from the car and bolts for suspending the parts that are below the frame,a ire dome and fuel hopper and a door for the same, an exterior casing having a lining of asbestus and an interior casing extending part way up and having openings at or near the top, whereby the air passing upwardly through the openings in the frame is heated within the casing, air pipes extending laterally and beneath the seat for the discharge of the heated air, and a iiue for the escape of the products of combustion, substantially as set forth.

3. The Vcombination in a heater for street cars, of a casing adapted to set beneath the seat of the car and having a lining of asbestus or similar' material, and air pipes extending laterally from the same beneath thel car seat, a frame having openings and forming the base for the casing, a heater supported by the frame and having an ash-pit below the heater accessible from outside the car, and a fuel hopper and door accessible from within the car, substantially as set forth.

Signed by me this 26th day of September,

JOSEPH A. LONG.A Witnesses:
