THOMAS R. WHITE, OF BOSTON, MASSACHUSETTS.

APPARATUS FOR HEATING CARS.

SPECIFICATION forming part of Letters Patent No. 375,521, dated December 2'7, 1887.

Applicatiou filed February .14, 1887. Serial 110.228.1369. (No model.) i

1 To aZZ whom it may concern:

Be it known that I, THOMAS E. WHITE, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and Improved Apparatus for Heating Cars, of which the following is a full, clear, and exact description.

My invention will first be described, and then specifically pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a partof this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a side elevation of the engine and the last car of a train partly broken away and in section, and Fig. 2 is a partial transverse vertical section through a car heated by my improvements. Fig. 3 is a longitudinal section'through'a coupling employed in carrying out the invention.

In carrying the invention into effect a vertical lever, a, is pivoted in the smoke-boXA of i an engine,having pivotal connection at the upper end with a damper, a, adapted to close the passageinto the smoke-stack, and similar attachment at its lower end with a damper, a", adapted to close over. a collared aperture in the bottom of the smoke-box, which dampers are operated, the one to close and the other to open, through the medium of a hand-lever, b, in the cab connected with the lever a in the smoke-box above or below its fulcrum by a rod, b, as shown in Fig. 1.

A blower, B, is mountedin the cab of the engine, operated by a small engine, B, or similar means, whereby air is supplied and equally distributed to the fire through pipe connected with the said blower and arranged within the fire-box beneath the grate. Within the apertures in the bottom of the smoke-box Aapipe or flue, D, is introduced, which pipe. sur-' rounded by an outer and much larger pipe,I), is made to extend beneath the'engine, the projecting ends being provided with a section of coupling, 0, hereinafter described. Upon the same shaft operating the blower B a second blower, E, is mounted, connectedwith the space (1, intervening the inner pipe, D, and outer pipe, D, the purpose of which is to supply fresh air to the chamber thus formed, which air is kept constantly heated by the hot pro ducts of combustion passing through the interior pipe, D.

Similar pipes, D D, are held suspended centrally and longitudinally beneath each car of a train,which pipes are adapted to be coupled toeach other and to the pipesof the engine in any suitable or approvedmanner. At regular intervals smaller semicircular pipes F are made to radiate from each side of the outer longitudinal pipes, D, and pass up through the floor of the car,preferably in front of each seat therein, a suitable register, 0, being made to cover the aperture formed by the entrance of the said pipes through the car-floor, as shown in Fig. 2. v

Upon the end of the pipes D and D, at the rear of the rear car of a train, a baffle-tube,H, is coupled,which baffle-tube is providedat its outer end with an inclosing-screen, h, and the under side of said tube, near the end, is pro vided with an aperture, h. The pipes may be coupled in any secure and well-known manner. In the drawings, however, apreferred form of coupling is illustrated in Fig. 3, in which it will be seen that one inner pipe, D, is provided with an integral flaring, mouth, M, and the opposing pipe D with a slightly flaring attached flexible packing, M. Thus when the two pipes are-brought together the one is firmly wedged in the other. The inner pipes are held in contact by the coupling 0 upon the outer pipes. This coupling is usually effected by causing an interiorly-threaded ring, m, .provided with a series of exterior knobs, m, to re- .volve freely upon a collar, m integral with the outer 'end of one pipe, D, an equivalent collar, or, having a threaded outer surface, being formed in similar manner integral with the opposing pipes D. When the two. pipes come together, the loose ring m is made to engage and screw upon the threaded collar m ,whereby a tight joint is effected.

The operation of the invention is as follows: Upon a fire being built the lower damper, a is closed and the upper damper, a, opened. This operation restores the usual draft to the fire. When sufficient steam has been generated to run the small engine B, and thereby the blowers B and E, the position of the dampers is reversed by means of the lever b from the cap,and all the products of combustion thereupon pass into the pipe D, draft being supplied the fire-box by means of the blower B, while the blower E constantly supplies fresh air to the chamber d,intervening the inner and outer pipe, D D. The hot products of combustion pass the length of the train, and upon reaching the bailie-tube H the smoke and gases pass off through the screen, the ashes and sparks falling between the track through the aperture h in said baflle-tube. The inner pipe, I), being heated to ahigh temperature by the products of combustion passing through it, heats in turn the air in chamber d, which air, passing upward ,is delivered in the car through registers in front of each seat.

It will be observed that by the apparatus above described a train is not only plentifully and economically heated without danger from fire, but that fresh air is constantly supplied to each car, and the smoke, gases, and cinders from the engine so disposed of as not to annoy the passengers.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a device for heating cars from the engine, the combination, with the smoke-box of a locomotive, a Ilue leading from thence bcneath said locomotive and cars, and a lever pivoted in said smoke-box carrying dampers, whereby communication may be opened or closed between said flue and the smoke-box or said box and the stack, of a concentric tube,

also extending beneath the locomotive and cars, and a blower for introducing air between said flue and tube and forcing the heated air to the ears, substantially as herein set forth.

2. In a device for heating cars from the locomotive, the combination, with the smoke-box of a locomotive, and a flue leading from thence beneath the locomotive and cars, said flue being provided at its extreme end with a baffletube, of a concentric tube, also extending beneath the locomotive and cars, a blower adapted to introduce air between the flue and concentric tube, and a series of transverse smaller tubes connected with said concentric tube, adapted to convey heated air at intervals into the cars, substantially as shown and described, and for the purpose herein set forth.

3. In a device for heating cars from the 10- comotive, the combination,with the smoke-box A, provided with dampers a a and a flue, D, leading from said smoke-box longitudinally a train,ol' the concentric tube D, an air-space, d, intervening said flue and tube, and a blower connected with said air-space, and a series of curved transverse tubes, F, uniting said airspace with the car, and registers 0, arranged above said tubes F in front of the seat of a car, substantially as shown and described, and for the purpose herein set forth.
