JOSEPH ASH BROOK SHINN, 0F NEIV YORK, N. Y., ASSIGNOR, BY MESNE ASSIGNMENTS, TO THE SAFETY OAR HEATING AND LIGHTING COM- PANY, OF NEW JERSEY.

SYSTEM OF AND APPARATUS FOR HEATING RAILWAY-CARS OR SIMILAR VEHICLES.

SPECIFICATION forming part of Letters Patent NO. 484,343, dated October 11, 1892. Application filed September 2, 1887. Serial No. 248,564. (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH ASHBROOK SHINN, a citizen of the United States, and a resident of the city, county, and State of New York, have invented a new and Improved System of and Apparatus for Heating Railway-Cars or Similar Vehicles, of which the following is a specification.

My invention relates to a system of car heating in which a main pipe connected with a source of heat-as, for example, a steamboilerconveys a heating medium to each car of a train through the instrumentality of a branch pipe, thus connecting the main pipe with fluid circulating and heating apparatus within each car. 7

' My invention consists in the organizations of apparatus hereinafter described, and then succinctly expressed inmy appended claims.

In the accompanying drawings, whichillustrate the apparatus employed in my improved system, similar letters and figures of reference indicate like parts.

Figure 1 is a longitudinal section of a portion of a car on the lineX X and X Y of Fig. 3, [the line X Y referring to the water-box and chimney-cowl at the upper left-hand corner of Fig. 1. The View shows the location of the systems of piping employed, as, also, a stove for heating the circulating water, when so required. Fig. 2 is a transverse section of Fig. l and shows the location of the piping systems and stove. Fig. 3 isa detail View in section of the expansion-joint employed. Fig. 4 is a plan view of a car, showing one method of piping a car, &c.

In the drawings, A is a railway car or carriage of any desired construction, in the end of which is located a stove B. This stove may be such as is commonly employed in connection with a hot-water-circulating system, or it may be of any design or construction to accomplish its purpose, which is, as previously stated, to generate heat and transmit same a coil of pipe 0 within the fire-pot.

said heat-generator is to heat the liquid system and to give direction to the circulating medium within each car, which is of prime importance.

In the drawings the stove shown is of the Well-known Baker type, and is provided with Located above the stove is a reservoir D, provided with a safety-valve E and perforated cup F, adapted to contain salt or other material for charging the circulating water and by the addition of which the water is rendered more capable of absorbing and radiating heat. Depending from the reservoir is the pipe G, which is carried to the floor and along both sides of the car, passing under and crossing the car opposite the stove and entering the coil 0 of the stove at H.

The coil 0 of the stove is carried out at I and upward into the reservoir D. It will be readilyunderstood that when the pipe system specified is partially filled with water or suitable liquid and heat is generated in the vi-- ciuity of the coil 0 that the liquid in the coil expands, is carried up to the reservoir, descends by pipe G, and so circulates around the car, at the same time radiating the heat of the liquid in the pipes. This circulation will be maintained as long as the heat generated in the stove exceeds that of the circulating liquid.

The system as far as described, a coal-burning stove being employed, is that now well known and commonly employed. Such systemI use as a part of my system and have herein designated it as the secondary system.

Referring now to the steam system, 10 indicates asteam-pipe carried under the car. It may be placed within the car. On the ends of the pipe are flexible coupling-tubes 11, with couplings 12. When a number of cars are coupled together, the pipe 10 forms an unbroken passage for steam from the source of primary supply, as from locomotive-boiler, (live or exhaust steam,) auxiliary boiler, or tender, or car, or stationary boiler.

13 indicates a branch pipe taken 0E the pipe 10, carried upward. The pipe 13 is tapped by the pipe 14, which is carried to the opposite side of the car, the object of this arrangement being for the purpose of controlhug the entrance of steam from the primary source bya single valve, as at 15. The valve is connected in any suitable manner with a thermostatic electric device, which when energlzed by a rise or fall of temperature above or below'a predetermined point serves to open or close the valve 15. Such a device 1s shown at 16 and 17.

18 is an ordinary cut-oft valve in the pipe 14,by which the steam can be cut ofi from the side of the car, to which the pipe 14 leads.

Referr1ng to Figs. 3 and 4, 19 indicates a pipe or drum surrounding the fluid-pipe G, and which gives off heat by direct radiation, and whichItheretore call a radiator. This radiator also imparts its heat to the pipe which it surrounds. The pipe G, however, is carried out at the end of the druin19 in order to connect the pipe with stove and reservolr and provide for the circulation of the contained fluid, in order to provide for the difference in expansion between the pipe G and drum 1.9. The expansion packing-joint (shown at 21, Fig. 3) is made. use of and consists of the gasket 22, screw-threaded to the pipe 19. The inner end of the gasket 23 s provided with a cone-shaped seat, and ly ing on the-seat and surrounding the pipe G are the conical divided or split rings 24 25, two rings being used, so as to break joints. The operation of the packing will be readily understood. The valve 15 being opened, the steam traverses the pipe 13 to the drum 19 or radiator, and by its pressure drives the conical rlngs along the conical seat and around the pipe, thereby contracting the diameter of the rings. The result is a steam-tight joint allowing perfect mobility of the parts. I make no claim to the invention of this joint,

but simply as to its application to mysystem of heating.

Referring to Fig. 4, the drums or radiators 19 are shown connected by the pipe 26, and located on this pipe is the safety-valve 27 and steam-trap 28. The pipe. 26 is not connected to the pipe 10. All the steam passing through the drums or radiators 19 enters by the pipes 13 and 14 and leaves the drum by the pipe 26 and, as condensed water, escapes by the trap 28 or, when the pressure of steam exceeds the determined pressure for the system, by the safety-valve 27.

The safety-valve 27 may be of any convenient design, but preferably such as will not have its action aifected by accumulation of salt from the brine in circulation.

Many changes can be made therein without departing from the intent of my invention.

I claim as my invention- 1. In a hot-water heating apparatus, the combination, with a successive series of water-vessels, each having a water cell or chamber and a heating cell or chamber, of pipes or ducts connecting the Water-chambers to form a circulating system, with a steam or heat supply pipe connected to the said heatingcells of said water-vessels, substantially as described.

2. In a car-heating system, the combination, with a system of water-circulating pipes within the car, of a main steam-pipe attaghed to the car and means for connecting it with a suitable generator, a steam-radiator within the car and surrounding said water-circulating system, and a branch pipe connecting said In witness whereof I have hereunto set my hand this 25th day of February, 1887.
