STREET-OAR HEATER.

SPECIFICATION forming part of Letters Patent No. 227,345, dated May 11, 1880.

Application ilcd January 24, 1880.

To all whom it may concern:

Be it known that I, GEORGE C. BOVEY, of Columbus, Franklin county, Ohio, have invented certain new and useful Improvements in 5 Street-Car Heaters, of which` the following is a specification.

This is an improvement on Letters Patent No. 211,963, granted to myself and George B. Kerper, February 4, 187 9, for street-car heater;

Io and the present invention consists in constructing the heater in such a manner as to cause it to occupy less space both underneath and within the car or other vehicle, and at the same time all danger of settin g tire to the car is 15 completely obviated.

In the annexed drawings, Figure l is a vertical section through the lower part of a streetcar provided with my heater, a portion of the latter being broken away and shown in section.

zo Fig. 2 is a vertical section of the heater taken in the plane of the grate-bars, the magazine and suspension-rods being omitted. Fig. 3 is a plan of the apparatus; and Fig. 4 is a horizontal section ot' the same, the section being z5 taken in the plane of the air-inlets of the hotair chamber and the central portion of the apparatus being broken away.

A B C represent, respectively, portions of the iioor, side, and one seat of a street-car or 3o other passenger-vehicle, a suitable opening being made in said floor to admit the heater, which is constructed as follows:

D represents a tire-box having a door, d, grate-bars E, and ash-pit F, which latter can 3 5 be emptied by simply opening a trap, Gr.

Located a suitable distance from box D, and surrounding three sides of the same, is a partition or wall, H, whose opposite ends are secured to the front plate of the heater in the 4o manner shown-in Fig. 4, while the upper and lower margins of this partition are attached to ribs or lugs projecting from the top and bottom plates of the lire-box, as represented in Figs. l and 2. Furthermore, this partition 45 is furnished with air-inlets h, which may be made in both of the sides and also inthe back of the same; or, if preferred, these inlets may take the shape of slots h', as representedin Fig. 4, which slots may be located near the 5o front plate of the apparatus, to compel the air to traverse a very circuitous route in passing through the heater. The annular space thus afforded between said partition and tire-box constitutes the hot-air chamber I.

The extreme outer casing or jacket, J, is 55 composed of one or more sheet-metal plates united to the front of the heater in the manner shown in Fig. 4, and securely riveted or bolted at j to the marginal flanges ot the top and bottom plates of the tire-box D. This 6o jacket incloses a space, K, known as the coldair chamber, which chamber has inlets lc of any sh ape. Said jacket projects some distance above the top plate of the heater, as at L, the margins of this extension being bent down at 6 5 Z, and then nailed or screwed to the car-floor, as shown in Fig. 3. Frvidently this bent portion or liange Z will be sutlicient to hold the heater firmlyl in position, provided the jacket is made oi moderately thick metal; but in or- 7o der to render the attachment ot' the heater more secure a number of stirrups or slings or suspension-rods, M, may be employed, their upper ends being bent down and attached to the tloor atm,whi'le their lower ends,m, grasp 75 the margins of the jacket and thebottom lian ge of the nre-box, as seen in Fig. 1.

It' preferred, the rivets or bolts j', that unite said jacket and iianges, may also pass through these suspension-rods. The re-boX D is snr- 8o mounted with a dome, N, to which is applied a smoke-pipe, O, the latter being, preferably, carried along underneath the seat C, and thence up at the corner of the car or on the outside of the same, as shown in my old patent. Gast 8 5 with or otherwise applied to this' dome is an inclined chute or magazine, I), having near its lower end a gate or cut-ott', R, whose handle r is to be engaged with a rack, S, or other device capable of maintaining said gate in a suit- 9o able position to regulate the flow of coal from said magazine to the fire-box. T is the charging-door of this magazine.

Openings U are made in the top plate of the heater immediately over the chamber I, to 9 5 allow the warm air to escape directly into the car.

The dotted lines V (seen in Fig. 2) indicate the position of a shield or guard that may be attached to the oor and seat of the car to pre- :oo

vent the passengers feet or garments coming in contact with the heated dome.

W W represent the customary internal Wheel-guards of a street-car.

By referring to Fig. 2 it will be seen that cold air enters at inlets 7c, then descends and passes Vthrough openings It into chamber I, where the air becomes heated by contact with fire-box' D before escaping at the outlets U, as indicated by arrowsin said illustration. Consequently this part of the apparatus insures a copious supply of pure warm air to the car or omnibus or other vehicle to which the heater may be applied, and at the same time heat is radiated from the' dome M and pipe O. One advantage of this -form of heater is that it is located Wholly under one of the seats, while in my old patent the apparatus is represented as extending completely across the car, and occupies considerable space under both seats. N ow, this old arrangement, besides being complicated, heavy, and expensive, is valso objectionable on account of it being in the way of the brake attachments on some forms of cars. Furthermore, the old apparatus concentrates too much heat at one place, and is liable to set tire to the straw in the cars; but all of these objections are obviated by the present construction, which affords a cheap, simple, and light apparatus that is situated wholly underfjeither of the car-seats, and does not in the least interfere with any form of brake attachrnents.

Anotherladvantage is its perfect safety from iire, as the prolongation L of the external jacket, J, prevents any appreciable degree of heat being communicated from the apparatus to the car-iioor orjto any straw or other covering spread upon the same.

A still further advantage results from the use of magazine P and its accessories, as the gate R can be so adjusted as to insure a con- Vtinuous supply of a greater or less quantity of fuel to the firebox D, the vibrations of the car causing a regular iiow of coal down said inclined chute.

1f preferred, the door T of this chute may be omitted, and the magazine may be extended up through seat C, as shown at X, a trap -door being` in this case hinged to the seat, so as to afford facility for charging said fuel-chamber T. Finally, the dome may be omitted.-

I am aware it is not new to surround the furnace of a car-heater with apartition inolosed by an outer jacket, as such a construction is seen in Letters Patent No. 67,770, issued August 13, 1867, to W. G. Kendrick. Therefore my claim to this feature of the invention is expressly limited to a street-car heater whose furnace has an external iire-door, an intermediate partition, and an outer jacket, which jacket is carried up a suflicient distance above the furnace or lire-box to prevent heat being communicated to the floor of the car, as herein described and illustrated.

I claim as my inventionl. A street-car heater consisting of afurnace, D, having an external tire-door, d, partition H, hot-air chamber I, cold-air chamber K, inlets h 7c, dome N, inclined magazine P T, and ventages U, the outer jacket, J, of said cold-air chamber being extended above the iire-boX at L and attached to the car-Hoor at l, as herein described, and for the purpose set forth.

2. In combination with a car-heater of the class specified, the outer jacket, J, and suspensionrods M, which rods are attached to the Hoor at m and are secured to the heater by the same bolts or rivets, j, that unite the jacket to the fire-box, as herein described.

In testimony of which invention I hereunto set my hand.

GEORGE C. BOVEY. Witnesses:
