MODE OF WARMlNG RAILWAY-CARS.

Specification forming part ot' Letters Patent No. 88,852, dated April 13, lSGQ;

are the cylinders at the lower corner oi the cars, through which the water flows from the steam-pipes to an air-tight tank, as set i'orth herein below.

rlhe steam-pipes I I I I I I and the transversepipes H and II arc herlnetically joined to prevent the possibility ot' steam escaping in the cars i; case of collision or other accident. I I I I I I may be laid in equal numbers under each row of seats, and also in the centcr passage between vthe rows of seats. They may be laid under the iloor, and be cased in by sheathing, made air-tight, and securely fastened to the joist on which the iloor is laid; or these steam-pipes may be placed over the main floor and be incased, as stated above. 'lhe end or transverse steam-pipes are connected with the pipes which extend through the pas-v senger-cars in equal number under each row of seats, and also through the center passage of each ear. Over these pipes is an uppcror false floor. On this false iloor, and extending through the whole length of the space be tween the supporters or legs ot' each seat, is a tlue and foot-rest, formed by securely fasteningtwo triangular end pieces ott-hose fines near the legs ot' the seats in a vertical position, and attaching to these end pieces two foot-boards, which shall at their upper edges approach within about two inches, 'and at their lower edges be firmly-attached to the edge of an opening in the false 'oor, thus forming a tlue under each seat, which will permit the heat from the steam-pipes to passfreely into the cars.

Cylinders J at the four corners of the car are firmly connected with pipes Il H, andre- Beit known that I, ARCHIBALD G. CRARY, a resident of thecity of Utica, in the State of New York, have invented a new and useful Improvement on the Mode or Process of Warming Railway-Cars .by Steam. My invention consists in constructing either y .above or below the main iioor in each railwaycar anadditional iooror platform at such distance from the main floor as will of itself, in connection with the sides and main tloor of y the car, form a'rectangular steam-chamber, or permit the occupation of the space between these floors by steam-pipes of sufficient size to contain the necessary quantities ofsteam to warm a'railway-car, and, by means of the appliances herein below set forth, supply the ya -boiler of a locomotive, or,`when the steamgenerator is used without the steam-engine,- 'supply the steam generator, with pure hot water; and I do hereby declare that the foli lowing is a full and exact description oi' the y construction and operation otl the same, referl. 4ence being had to the accompanying drawings, and to the letters of reference marked i thereon, making partof this specification, in .which- Figure 1 is a perspective view of a car, the vseats'and. the lues under the seats, the hood, f andsocket designed to receive the end ofthe j -steam-pipe,.which is connected with the steampipes of the next preceding car. Fig-2 is a view of the steam-pipes and the cylinders at the corners ofthe cars. Fig. 3 represents the small cylinder and the ,valve attached to its lower end, which is inclosed in the large cylinder above named. Fig. 4 is a longitudinal elevation, showing the body of a car with the y topl removed to exhibit the steam-pipes and ceive all the water condensed from the steam.. the cylinders at the lower corners of 'the car. When cylinders I are'partly lled with water, Fig. 5 is a sectional view of the cylinders K cylinder K iloats and raises valve O. This and P and of the valve O in their relative poopensthc aperture of the valve, and permits sitions. the water to escape from the car into the A A A A, Fig. 1, are the seats in a railwayeduction -pipe M, and thence through theA car. B B are the iiues under the seats. G is eduction-comluits into the air-tight tank. the front platform. Under the platforms the G, Fig. 'l in Drawing 2, is a steam-chamber, induction and eduction pipes are situated. which may be substituted for steam-pipes F represents the hoo-d.

This causes them -2 i Sasse air-tight taiiks, to be pumped into the boiler or steamgenerator'to be converted i'ntosteam, thus furnishing heat to the cars, and, by the use of pure water, avoidingthe destruction of the boiler by the sulphur which is generally contained in water, and also avoiding the corrosion of the pipes in the boiler by lime.

his invention constitutes a part of my lap-l through which'the drip or Water condensed 1.110111 the steam viiows Aback on the opposite side of the train of cars to the tank. These large steam-pipes or leaders are,at each of their been granted me 'in 1868 and 1869.

I am aware that some of the special devices which I use to carry out this part ot' my in vention are not new with ine, but the like arrangement for the like purpose has never before been made that I am aware-of.

Having thus described my invention, what I claim therein as new and useful, and desire to secure by Letters. Patent of the United States, is-

l. The application ofthe drip or watercouden'sed from steam for the purpose of supplythe Valves in these conduits being similar to those describedjin Patent No. 87,472. The wal ter is retained in the car to supply heat'when the locomotive is temporarily detached. These pipes -or leaders may be situated inside of the several cars, similarly to pipe L K M, Fig. 2, Drawing 1, or on the outside ot a'car, as seen in M, Fig. 2 of Drawing 2.

Rand R R. are the platforms. -IJ P, Fig. l ot' vvDrawing 2, is a sectional view of cylinder J, (also seen in Drawing 1,/in` Fig. 2,) in which the ball-'socket or valve L or cylinder-K of Fig. 2 in Drawing. l is situated. t

vValve K and the ball-valve L are of less specific gravity than water, and arevof greater comotive is temporarily detached from a train of cars, substantially as herein shown.

v2. The float-valve, in connection with the re turn-pipe E, when used.for the purpose set forth.

3. The foot-rest B, made as shown, when used as a register and foot-rest.'

4. The combination of the double floor, constructed as set forth, the induction and eduction pipes, and valve and foot-rest, substantially as described.

to rise when the water accumulates around them, and permits theavater to escape into the conduit E with the force ot' the action of the steam.

The operations of the steam-chamber, the steam-pipes, and the intermediates or conduits between the'cars, described hereinabove, are to condense the steam `from the steam-generator and the escape-steam from the boiler, and to return the water condensed from the steam to
