CAR-HEATER.

SPECIFICATION forming part of Letters Patent No. 399,633, dated March 12, 1889.

Application filed May 3l, 1888.

To @ZZ whom, it T11/(ty concern:

Be it known that we, FRANK RUPREOHT, a subject otl the Emperor of Germany, and FRANCIS G. BATES, a citizen of the United States, residing7 respectively, at Syracuse, in the county ot Onondaga, State ol New York, and Philadelphia, county ot' Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Car-Heaters, of which the following is a specification.

This invention is designed to he used in connection with pipes conducting steam through railway-cars t'or heating the same; and the ohj ect ot' the invention is to close the pipe at opposite ends of the car automatically with the disconnecting of the said car from the train; and to that end our invention consists in the novel construction and combination, with two sections ot' the car-heater pipe, of a valve-case interposed and connected to said sections and valves arranged conversely in relation to each other in the case and held mechanic-ally in closed position under diiterent degrees of resistance, all hereinatteil more fully described, and specifically set forth in the claims.

In the annexed drawin Figure l is a side elevation ot the end portions olf two adjacent cars equipped with our invention. Fig. 2 is a detached enlarged top plan view of the valve-case without its cover and a portion of the interior broken awayto illustrate the form and arrangement ot' the valves and their seats; and Fig. El is a transverse section on line .1' .1', Fig. 2.

Similar letters of reference indicate corresponding parts.

C represents a valve-ease secured to the car in any suitahle position, though preferably under the plattform l) on the end oi' the car, as shown in Fig. il ot' the drawings. Said valve-case is pr i vided at the eenteisol its opposite ends with pipe attachments u a', and is interposed and connected tothe steam-pipe sections A A', one of which leads to the radiators in the car, and the other receives steam either direct from the engine connected to the car or from an intervening car or cars. The

other pipe-section, A, connects, as hereinafter described, with a similar valve-case, O, se

cured to the adjacent car. The interior of the case O is provided at opposite ends with two compartments, C O,1'ormed by a frame, I), extended across the ease and secured in position in any suitable and well-known manner. i

Longitudinally through the frame D, at op posite side of the longitudinal central line, are extended channels c c, which thus connect the two compartments C O, said channels being each formed with a valve-seat, t, at one end and converse to that of the other channel. In the channels c c are placed longitudinallymovable valves n y1" disposed reverse in relation to each other, and provided with hearings by which they rest on the seats when the valves are in their closed position. The Shanks u. of the valves are formed with spiral iianges c and intervening spiral grooves c', so that the steam can enter the channels c c, and it" under sufcient pressure to lift the valves from their seats the valves receive a rotary motion, and thus change their positions on their seats, and thereby cause the same to wear evenly. These valves are held 1neehan ically normally in their closed positions under different degrees of resistance, preferably hy means ot spiral springs d d, held against the closing ends of the valves hy adjustingscrews l Z, working in screw-threaded apertures in the end plates of the valve-case O, and provided at the inside of said case with a collar, l', against which one end ot' the spring d bears. By means of said screws the tension of the springs is to he so adjusted that the valve y1f', which has to resist the hacle pressure of steam from the pipe A leading into t-he car, receives greater pressure from its spring d than the valve which has to resist the pressure. of the steam received from the engine. The eiil'ect of this arrangement of the valves if r is a-s follows Then the caris connected at opposite ends to a train and the steam is allowed to pass trom the locomotive through the pipe A into the chamber C, the va-lvc t will he forced open by said current-of steam while the spring d holds the valve 1" closed, and thus the steam is compelled to pass from the chamber O through the pipe A to the radiators in the ear, and from thence the (No model.)

IOO

steam passes in the same manner through the cha nber C on the opposite end of the car and into the radiators in the adjacent car. It will be observed that this arrangement is adapted to operate with either end of the car toward the engine. n n denote drip-faucets for letting the water of condensation out of the Valve-chamber. The pipe-section A', which projects from the end of the valvechaniber C facing from the car, is provided with a stop-cock, e, by which to cut off the steam completely when desired, and to that end of said pipe-section is connected a telescopic pipe-coupling, 71 by which to connect said pipe-section with a pipe projecting' from a valve-case, C, connected to the end of the adjacent car.

Having described our invention, what We claim as new, and desire to secure by Letters Patent, isv l. In combination with two sections of a car steam-heater pipe, a valve-case interposed and connected at opposite ends to said sections and valves arranged conversely in relation to each other in the case and held mechanically in closed positions under differ- 3. In combination with the pipe-sections A A', the case C, provided with the pipe attach* ments a d at the centers of its ends, and having thereat the compartments C C', intervening longitudinal channels c c, connecting said compartments at opposite sides of the longitudinal central line of the case, and each provided with a valve-seat reverse from that of the other, valves n fu', .movable in said channels and closing against the aforesaid seats, and springs (l d, adjustable in tension and pressing the valves onto their seats, substantially as described and shown.

4. In combination with the pipe-sections A A, the case C, interposed and connected to said pipesections, compartments C C in opposite ends of the case, longitudinal channels c c, connecting the compartments, reverselydisposed valves t' o in said channels, springs d d, holding the valves in their closed position, the stop-cock e, connected to the pipe-section A', and the telescopic coupling h on said pipesection, substantially as described and shown,

In testimony whereof We have hereunto signed our naines, in the presence of two witnesses, at Syracuse, in the county of Onondaga, in the State of New York, this 26th day of May, 1888.
