MAURICE J. \VALSH, OF NEW YORK, N. Y., ASSIGNOR, BY MESNE ASSIGN- MENTS, IO LOUIS FITZGERALD, OF SAME PLAGE.

APPARATUS FOR HEATING CARS.

SPECIFICATION forming part of Letters Patent No. 264,050, dated September 5, 1882,

Application filed May 23, issa.

To all whom it may concern:

Y Be it known that I, MAURICE J. WALSH, ot' New York, in the county and State ot' New York, have invented a certain new and useful Improvement in Apparatus for Heating (Jars,

of which the following is a specitication.

My improvement relates to apparatus for heating ears, comprising pipes which eXtend from the boiler of the locomotive through the ro train, and which return the water of condensation to the said boiler or to the tender-tank.

The improvement consists in certain novel combinations ot' parts comprised in such an apparatus, and hereinafter fully described.

In the accompanying drawings, Figure 1 is a plan ot' an apparatus embodying my improvement, a portion of a locomotive-tender and a portion of a car being represented in dotted outline. Fig. 2 is an elevation of the same, 2o and Fig. 3 is a sectional view ot' a cock employed in the apparatus,

Lil

Similar letters ot' reference designate corresponding parts in all the tigures.

A designates apipein a locomotive of which I give an arbitrary representation, marked B, the rear en-d ot which is lettered j'. Similar pipes extend along a tender of which there is an arbitrary representation, B', and along a car ot'which there is an arbitrary representation, B2. Theends otl the tender are lettered j", and the front end of the car is lettered f2. O designates pipes extending outside the pipes A. Flexiblepipes A C', arranged one -within the other, extend beyond the ends of the locomotive tender and car from the sections ot the'pipes A G, which are respectively located in the locomotive, the tender, andthe car. At the ends of the pipes A C, which extend through the car, cocks D are arranged. 4o The plug ot' each ot' these cocks has two ports, a c, which, when the plug is properly turned, will establish communication between the pipes A A and G C. The plug also has a port, b,

latter the contents of the former.

(No model.)

end of the pipe A arranged in the locomotive is intended to communicate`with the boiler thereof, and this pipe is provided with a cock, E, whereby the amount ot' steam passing through itmay be regulated. The steam passes along' this'pipe A through the iiexible pipes A which extend between the locomotive and its tender, thence along the pipe A of the tender, thence along the flexible pipes A which extend between the tender and the car. The cock D at the frontend ofthe ear is turned so that the steam passes through the flexible pipeA between the tender and car into the outer pipe, C, ofthe car, through which itpasses to the cock D at the rear end thereof. This cock is turned so that the steam passes intothe pipe A of the car, whence it passes to the cock D at the front end ofthe car. From said cock the steam passes through the pipes C', that extend between the ear and the tender. Entering the pipe G of the tender, it passes to the iiexible pipes C that extend between the tender and the locomotive, and thence it passes to the pipe O of the locomotive. The pipe G ot' the locomotive communicates under control of a cock, F, with a pipe, G, which leads to a tank, H, on the tender B'. The cock F is an 75 ordinary three-way cock, and ordinarily it is turned to allow ot' the contents ofthe pipe G ot' the locomotive passing into the pipe G. By the time the steam reaches the pipe C ot' the locomotive it is condensed into water, and this water iiows into the tank H, where it may be utilized i'or supplying the boiler of the 1ocoinotive.

I designates a pipe leading from the cock F to an injector, J, arranged on the locomotive. A pipe,l K, leads from the boiler ot' the locomotive to the injector and supplies it with steam under control ot'a cock, L. A pipe,

M, leads from the injector, and from it leads a branch pipe, N, to the tank H ofthe tender, 9o and a branch pipe, O, leads to the boiler of the locomotive, a three-way cock, P, being employed to control communication between the pipe M and the branch pipe N, cr between said pipe M and the branch pipe O.

When it is desired to draw oft any water 2 ecaoo formed bycondensation of steam in the pipes A A' G G the three-way cock F is turned so as to cut oft' communication between the pipe O of the locomotive and the pipe G, which leads to the tank H, and establish commuuication between the said pipe U and the pipe l, leading to theinjector J. The cock Lis also turned to permit steam to pass through the pipe K to theinjector, and the three-way cock P is manipulated to establish communication .between the pipe M and the pipe N, which leads to the tank Hot' the tender, or with the pipe O, which leads to the boiler of the locomotive. The injector is then rendered operative, whereupon all the water willbe drawn out of the pipes A A (l C', either into thetank H or into the boiler of the locomotive, according to the way the cock P is turned. rlhe water, being` drawn off the pipes A A (l C', can do no damage therein, as it might do if allowed to remain and freeze. This is important, as owing to the train sometimes stopping on a grade it may often be impossible to drain the pipes by gravity. The tlexible pipes A C are employed to allow ot' the motion which necessarily occurs between the different parts of a train. Sections ot' these pipes are furnished thelocomotive, the tender, and the car, and are united by couplings Q, which may be of any suitable construction. The pipes A G of the car preferably extend around within the car close to the side walls, as indicated in Fig. 1, where but little more than one longitudinal halt' of a oaris represented. The pipes are for a portion of their length surrounded by a jacket, R, containing a mixture of two parts, by weight, of caustic soda, eleven parts of acetic acid, and thirteen parts of water. This compound retains a large amount of heat latent, and gives it off slowly, wherefore it is very desirable in acar-heating apparatus. It is much more desirable when comprising water as an element than it' it lacked this element, for it is then much more effective.

V What I claim as my inventiomand desire to secure by Letters Patent, is-

l. The combination, with the pipes A A C C', extending along a train and provided with the cocks D, of the pipes G l, the tank H, cock F, injector or pump J, the pipe K, and a pipe or pipes leading from the injector or pump to the said tank H, all arranged and adapted to operate substantially as specified.

2. The combination, with thepipes A A C C', extending along a train and provided with cocks D, of the pipes G I, the tank H, cock F, injector or pump J, the pipe K, the pipes M, N, and O, and the valve or cock l), all arranged and adapted to operate substantially as specified.
