CAR-HEATER. i

SPECIFICATION forming part of Letters Patent No. 381,490, dated April 17, 1888.

Application lcd November 12, 1887. Serial No. 254.979. (No model.)

To aU whom; it may concern:

Be it known that I, CnmsTmN W. Winon- NG, Jr., of Valhalla, in the county of Oconee and State of South Carolina, have invented certain new and useful Improvements in Car- Heaters; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

This invention relates to that class known as railroad-car stoves, and has for its object to automatically extinguish the tire in the stove in case of an accident, no matter whether the car upsets or becomes detached or uncoupled, thereby preventing accidents from ire, which frequently is disastrous in its results.

With these ends in view my invention consists in certain novel features of construction and combinations of parts, more fully described hereinafter, and particularly pointed out in the claims.

In the accompanying drawings, Figure l is a central vertical section of my complete device in a car. Fig. 2 is a top plan view with the operating-weight removed. Fig. 3 is a detail view of a plug and operating-lever, the outer casing or shell of the stove being partially broken away; and Fig. 4 is a detail perspective view of the operating plate or weight and the manner of holding it in its normal po- Sition.

In the drawings, the reference-letter A represents the body portion of a car, in the end of which is placed the stove, as usual.

B is the repot of the stove, provided with the usual grate, beneath which is located an ash-pit, b. The top plate, b', of the re-pot is provided with a central opening to admit the lower end of the smoke-flue d, which extends upwardly through the top of the car. Surrounding the smoke-flue and located a suitable distance directly above the top plate, b', of the fire-pot is a water-reservoir, O, which is provided with a central tube, c, extending through the bottom of the reservoir and being rigidly secured to the top plate, b, around the opening through which the smoke-flue extends, the

upper end of said tube being open and not quite reaching to the top or cover c2 o f the reservoir, so that when the stove is tipped over the contents of the reservoir will have free access to the'interior of the tube, as the smoke-due passes upward through the tube c. Said tube is constructed of such adiameter as to leave an annular air-spacebetween the tube and smoke-due, so that the water in the reservoir will not become unduly heated, and also to allow a free passage for the water, as will hereinafter appear. the smoke-flue through the water-reservoir and tube c are the partitions C, which divide the reservoir and tube into compartments, and the bottom of each compartment in the waterreservoir is provided with an opening, d, having a beveled embossment, d, around its upper edge.

Secured to the bottom ofthe water-reservoir and communicating with the same at each opening d are the outlet-pipes D, which pass through the top plate, b', of the fire-pot, and are bent inwardly toward each other and the center of the fire-pot, so as to open directly over the cent-er of the fire. Covers on, arehinged at their upper ends to the lower open ends of the outlet-pipes D in such a manner that the covers will tightly close the ends of the pipes by their own weights, but being free to swing open if the slightest pressure is exerted upon them from the inside of the pipes. Thus the water passing from the reservoir through the pipes in case of an accident will have free passage to the iire, but the products of combustion will be prevented from having access to the interior of the outlet-tubes.

Beveled plugs d3, preferably formed of rubber or other suitable material, are normally located in the` openings d', and are provided with a firm seat therein by means of the beveled embossment d2.

Levers E are pivoted in a slot, n, in the outer sides of each outlet-tube D, and the inner ends of said levers are provided with up- Wardly-projecting arms @,adapted to normally rest in contact with the bottom of plugs d, Rods F are pivoted at their lower ends to the outer free ends of said levers, and from thence extend a suitable distance above the removable cover c2 of the water-reservoir, said rods Extending laterally from IOO being held iu position and loosely passingl through guide-ringsj, located upon the outer surface of the water-reservoir.

Forked ears h project from opposite sides of the smoke-Hue at a suitable distance above the top of the reservoir. A circular weight or plate, II, loosely surrounds the smoke-flue above the waterreservoir', and is provided on its upper surface with ears h to engage the forks of ears hrupon the smoke-flue, and said forked ears h .are provided with apertures adapted to register when ears h' engage the forks of ears 71..

A vertical lever, G, 4is pivoted to the car A at g', the lower end of which extends through a slot, g, in the bottom of the car, and the opposite free end of said lever extends up to the top of the carto a point about opposite the ears h upon the smoke-flue, and pivoted to the upper end of said lever is a laterallyfextending supportingrod, P', which is provided with a forked end, p, to embrace the smoke-fine and enter the registering apertures in the ears h and h, and thus removably hold the weight or plate H in position above the ends of rods F.

An operating-rod, P, is pivoted to the lower free end of the lever G and extends beneath the bottom of the car, and the opposite end of said operating-rod P is in engagement with.

the coupling mechanism or the bumpers of the car in such a manner as to be pushed violently in case the cars are thrown heavily together. Valves o are hinged over openings R in the smoke-flue at the bottom of everyr compartment,',so as to swing inwardly when water enters the tube c and allow it to ow'into the nre-pot. l

A water-reservoir, N, is placed beneath the ash -pit of the stove and is provided with tubes n', communicating with its interior and extending upwardlythrough apertures n in the bottom of the ash-pit, and the tops of said tubes are provided with hinged coversn, so that if the stove were overturned the water would pass from reservoir N through tubes n into the fire through the grate.

The reservoir G is provided with a removable cover, cz, whereby the water in the reservoir can be renewed; but the height of the water in the reservoir should be kept some distance below the top of tube c to prevent water from accidentally getting into the same. Said cover c2 is provided with steam and hotair outlet ports or apertures t.

The operation of my device is as follows:`

The various parts being arranged as shown in Fig. 1, if the cars were to be thrown heavily together, as in a collision, the rod P will be thrown violently rearward by the coupling or bumpers of the cars, which will withdraw the forked ends of the rod P from the holes in the ears h and h', and thus allow the Weight or plate H to fall upon the ends of the lever-operating rods F, and thearms upon the levers will force the plugs from their seats, and the water will rush through the outlet-pipes into the fire and extinguish the same. In case the car was tipped over without operating the lef ver* and plug mechanism, the `water in the upper reservoir will enter the top of the tube o, pass down said tube, and flow through the apertures and the smokefiue into the fire,and water will also flow into the fire from the reservoir beneath the stove, as before described. It is evident that numerousslight changes might be made in the form and construction of my device without departiugfrom the spirit and scope of my invention; hence I do not wish to limit myself to the form herein described. l I

Having thus fully described my invention, what I claim, and desire to secure by Letters .Patent of the United States, is

1. The combination,witha stove and a reservoir located above the same, of tubes cou-A necting said reservoir with the interiorof the stove, means for normally closing said tubes, A
