CHARLES E. STRUCK, OF NEWARK, NElV JERSEY.

CAR-H EATER.

SPECIFICATION forming part of Letters Patent No. 437,839, dated October '7, 1890. Application filed May 21, 1889. Serial No. 311,513. (No model.)

.To all whom it may concern:

Be it known that 1, CHARLES E. STRUGK, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and use ful Improvements in Car-Heaters; and I do hereby declare the following to be afull, clear, and exact description of theinvention, such as will enable others skilled in the art to which it appertains to make and use the same, ref erence being had to the accompanying drawon, which form apart of this specification.

The object of this invention is to secure a more perfect diffusion of the heat in horsecars, to obtain a better ventilation in connection with the process of heating, to economize the consumption of fuel, to reduce the cost of production, and, generally, to secure a more perfect and efficient stove or heater for horsecars.

The invention consists in the inipro ved carheater and in the arrangements and combinations of parts, substantially as will be hereinafter set forth, and finally be embodied in the clauses of the claim.

Referring to the accompanying drawings, in which like letters indicate corresponding parts in each of the several figures, Figure 1 is an elevation of the improved heater partly in section. Fig. 2 is a plan of the same. Fig. 3 is a central vertical section showing the relation of the heater to the car seat. Fig. 4 is a detail elevation, partly in section, of a valve or damper arranged in connection with the ash-pit, and Fig. 5 illustrates a construction of the grate which is preferably employed.

In said drawings, 0. indicates the body of the car, 12 the seat thereof, and c a portion of the flooring. Beneath said seat is arranged the stove or heater (1 of the improved construction.

6 indicates a base-plate upon which the body of the stove is constructed, said plate being of cast-iron in the form of a shallow pan fitted in an aperture cut out of the flooring. Said base-plate is preferably provided with upwardly-projecting ears or eyes a 6, through which keys f f may be passed to lock the base-plate in position. The base plate is let into the flooring, as described,'to secure lugs, and to letters of reference marked there" more ample space and to bring the ash-pan below the car without giving to said pan unnecessary depth.

Above the base plate e is arranged a firebrick cylinder or fire-pot g, disposed around a central perforation g in said base-plate, and held in place by lugs or keepers h, cast on or secured to the base-plate. Around the cylinder is arranged a casing i, of sheet metal, a hot-air chamber j being formed between, which is closed at the top by a flaring ring in, resting on the top of the fire-pot and engaging the inside of the casing, as shown in Figs. 1 and 3. At the top of the casing is arranged a cap or cover Z, having a resemblance to a truncated cone. This rests on the top of the casing and closes in the fire-chamber m, as will be understood upon reference to Fig. 3. The said cap or cover I is preferably held in place by tie-bolts n, which pass up through the base-plate and are secured in lugs or'ears 0, formed at the lower edge of the cap. \Vithin the cap is an opening 19, provided witha door or slide, through which opening coal may be supplied to the fire-pot. The chimney-pipe (1 also passes through the walls of the cap, the same extending longitudinally beneath the seat in the usual manner.

The ash pan or pit r is formed beneath the base-plate, being, either secured therein by screws or rivets or cast in one integral piece therewith.

On the outside of the car, at the back of the stove, or opposite the side having the coalsupply inlet, is arranged the outlet-aperture s for ashes, and at the opposite end back of the said pit or pan is a valve or damper t, which is provided with a handle it, which latter extends upward through the base-plate, so as to be manipulated from the inside of the car either to close or open the damper.

The base-plate is perforated at n to allow fresh air to enter the hot-air chamber j from the outside of the car, and the casing 71 is likewise perforated, as at n to allow the air after having been heated to pass into the car.

At the sides of the heater are pipes or ducts o, which extend through the base-plate and convey fresh cold air to the vicinity of the top of the heater, the pipe being perforated, as at w, to circulate and spread the air, and

ICG

thus the under side of the seat 6 is not unduly heated to the discomfort of the passengers, as heretofore, but the temperature at this point is brought to a proper equality with the other parts of the car.

At the front of the stove or heater is placed a screen 10, to protect the heater from the feet of the passengers, or vice versa.

The fire-pot g is provided with an ordinary grate 20 v Having thus described my invention, what I claim as new is= In a car-heater, the combination of the perforated base-plate, the fire-pot having the flanged top and resting on the base-plate, the I 5 the other end engaging lugs on the conical 2o cap.

In testimony that I claim the foregoing I have hereunto set my hand this 20th day of April, 1889.
