iairenr WILLIAM E. DEPP, OF BROOKVILLE, PENNSYLVANIA.

SPECIFICATION forming part of Letters Patent No. 365,975, dated July 5, 1887.

Application filed February 15, 1887. Serial No.

To. all whom it 71mg] concern.-

Be it known that I, WILLIAM E. DEPP, a citizen ofthe United States, residing at Brookville, in the county of Jefferson and State of Pennsylvania, have invented new and useful Improvements in Apparatus for Heating and Ventilating Railway-Cars,of which the following is a specification.

My invention relates to an in'iprovement in apparatus for heating and ventilating railway-cars; and it consists in the peculiar 0on struction and combination of devices that will be more fully set forth hereinafter, and particularly pointed out in the claims.

In the drawings, Figure 1 is a vertical longitudinal sectional view through portions of a steam-locomotive and a railway-car provided with a heating apparatus embodying my improvements. Fig. 2 is a transverse sectional view taken on the line 00 a: of Fig. 1. Fig. 3 is an enlarged vertical longitudinal sectional view of a portion of the apparatus illustrated in Fig. 1. Fig. 4t. is an end elevation of the heater.

The object of my invention is to provide an apparatus for heating cars without the danger of setting fire to them in the event that the train is wrecked; and this object I accomplish by means of the hereimatter-described mechanism.

A represents the boiler of a locomotive of the ordinary construction. Under the said boiler,and arranged transversely with relation thereto, is a cylindrical heater, B, which comprises an outer shell, longitudinal tubes O, which extend through the said shell and have their outer ends open and communicating with the outer air, the inner ends of the said tubes communicating with the discharge-opening D in one end of the casing and common to all of the tubes. A series of pipes, E, extend longi-- tudinally through the boiler and communicate at one end with a dome or case, F, which is located in the smoke-box, and at the opposite end the said tubes communicate with a similar dome or case, G, which is arranged on the rear end of the boiler. A tube, H, of suitable di-' ameter, connects the discharge-opening D of the heater with the case or dome F, and a suitable flexible tube, I, is attached to and eX- tendsfrom the dome or case G. The exhaust- ..|,702. (No model.)

ports of the steam-cylinders are connected to the heater B by means of tubes K, and from the heater extends a pipe, L, the upper end of which is arranged under the lower end of the smoke stack of the locomotive.

Each car of the train is provided with a pipe, M, that is arranged under the bottom of the car and extends throughout the entire length thereof, and from the said pipe,at suitable distances apart, extends a series of branch pipes, N, that pass through the floor of the car,and are open at their upper ends and provided with valves or registers 0, whereby the openings in the said branch pipes may be either entirely or partly closed.

P represents a fan or blower, which is arranged on the rear end ofthe locomotive-boiler and communicates with the dischargepipe I. This fan or blower is operated by means of any suitable steanrengine, with which the locomotive'may be provided for this purpose. Such an engine is represented diagrammatically in Fig. 1 at R.

The pipes I and M are provided with suitable couplings, S, whereby they may be connected together when the locomotive is coupled to the car. Any suitable number of cars pro vided with my improved apparatus may be coupled together to form a train, as will be readily understood.

The operation of my invention is as follows: When the fan or blower is operated, it causes air to be forced into the heater through the tubes 0, and it is heated therein by means of the exhaust-steam from the engines of the loco motive,the said exhaust-steam passing through the pipes K into the heater and from the same into the smoke-box of the locomotive through the pipe L, as before described. 7 The air,after being heated in the heater, is forced through the pipe E into the tubes E, which are arranged within the boiler and above the waterthrough the said tubes it becomes superheated to a very high degree. The blower forces the heated air through the pipeI into the pipe M. under the cars in rear of the locomotive, and from thesaid pipe M the air passes through the valves or registers 0 into the car, thereby warming the same to the desired temperature. Vhen a number of cars are coupled together,

line thereof, and as the air passes rearwardly the hot air passes through the pipes M from one car to another throughout the entire train, thus serving to warm all of the, cars.

A heating apparatus thus constructed will be found of great practical utility, is designed to warm the cars thoroughly, and cannot set them afire in case the train becomes wrecked.

In warm weather the pipe I is connected to a pipe, T, which is represented in dotted lines in Fig. 1, on the boiler, the said pipe T communieating at its front end with the outerair. Cold air will be forced through the pipe T by the fan or blower when the latter is in motion, and forced through the pipe I into the pipes under the cars and supplied to the same, thus assisting in ventilating the cars and making them entirely comfortable.

Having thus described my invention, I claim 1. In a system for heating and ventilating railway-cars, the combination of the locomotive having the heater'B, the pipes K,connecting the same with the exhaust-ports of the engines, the escape pipe L, leading from the heaters to the lower ends of the smoke-stacks, the pipes G, open at one end and extending through the heater, to conduct air through the same, the pipes lVLcommunieati ng with the interiors of the cars, and the pipes connecting the-pipes O and M to supply the latter with heated air from the former, substantially as described.

3. A steam-locomotive having the heating appliancesfo'r railway-cars, consisting in the heater B, connected with the exhaust-ports 0f the steam-cylinders, the pipes 0, extending through the heater B and communicating at theirouter ends with the outer air, the superheatingpipes E,extending through the boiler,

the pipe H, connecting the superhcat-ingpipes E and the pipes 0 together, and the pipe eX- tending from the superheating-pipes to supply hot air to the cars, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

WILLIAM E. DEPP.
