UNITED sirA'rEs PATENT oEErcE. ROBERT M. DI-XQN, 0F EASTORANGE, NEW JERSEY,- ASSIG-NORl TO SAFETY CAR HEATING LIGHTING COMPANY, A CORPORATION 0E NEW JERSEY.

vHEATING SYSTEM.

Be it known that I, ROBERT M. DIXON, a citizen "-of the United States, residing at East Orange, in the county. of Essex, and State of vNew Jersey,.have invented certain new and useful Improvements in` Heating Systems, of which the following is a full, clear, and exact description, such' is will enable-others skilled` inthe art. to which it appertains to'make and use the same.

This invention "relates'jv to heating'appa-l ratus, and moreparticularly to heating apparatus of the low pressure type adapted for use in railway cars or similar structures.

One of the objects of the invention is to rovide new and improved means for'heatmg and Ventilating a railway car.

Another. objectl of the invention is to provide apparatus of the abovel character` such that it may be employed for heating and ventilating the car, or for ventilating the car without heatin the same.

Other objects wil be in -part obvious and in part pointed out hereinafter.

The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction'hereinafter set forth and the scope of the application of which will be indicated 'in the following claims.

In the accompanying drawings wherein is illustrated one of thevarious possible embodiments of my invention, Figure 1 is a view in perspective showing-the floor plan of a railway car and heating and Ventilating apparatus i constructed in accordance with the invention. Fig. 2 is a vertical sectional view taken substantially on the line 2-2 Fig. 1; and Fig. 3 is a similar view of a portion of the apparatus shown in Fig. 2, but showing a valve employed in the apparatus in a different position.

Similar reference characters refer to similar parts throughout the several. views of the drawings.

Referring' now to the drawings 1 indicates the floor of a railway car, and 2 the train pipe which extends longitudinally of the floor beneath thesame.

3 denotes a feed conduit which is located beneath the floor of the car, into which leads a conduit 4 which extends downwardly through vthe floor of the car, an apertured Specification of Letters Patent.

plate as at 5 covering the upper end of conduit 4. In the present instance conduit 4 and'theforward end of conduit3 are formed integral' with each other.` v

An injector formed by a plurality of serially arranged members (3 is located in feed conduit 3 adjacent its point of communication with conduit 4, said injector being connected wlth the train pipe 2 as by means ofa .branch pipe 7 having a valve 8, the stem 10 of which extends upwardly through the ioor of the car-and is provided withan operating handle 11. In the present instance, a reducing valve is interposed in pipe 7 between the train pipe and the injector, said reducing valve being illustrated conventionally at 12. Connected with the opposite end of feed conduit 3 is a conduit 13 which extends upwardly through the Hoor4 of the car,'thence through the roof thereof and is open to the atmosphere. In the drawings the upper end of conduit 13 and the roof of the car have been omitted. Conduit 13, intermediate its ends, is provided with a valve chamber 14 land leading from the lower portion of this valve chamber is the feed end of a radiating system 15 which in the present instance extends longitudinally of the car, the discharge end of the radiating system leading into the uppe-rportion of valve chamber 14. A valve 16 is located in valve chamberlflf, said valve when occupying theposition shown in Fig. 2-of the drawings operating to close communication between the feed and discharge ends of the' radiatingsystem, whereby the heating medium passing upward through the lower end of conduit 13 will be compelled to'pass through the radiating system,

. thencethrough the upper end of conduit 13 to the atmosphere. Valve 16 is capable o f being rotated within chamber 14 to the position'show-n in Fig. 3 of the drawings to-close communication between the lower end of collecting in the system will be discharged- .beneath the floor of the car.

Having thus described the construction of this embodiment of my invention, the operation thereof may now be understood. With valve h6 in the posit-ion shown in Fig. 2 of the drawings, the steam passing through the injector 6 will draw air through conduit 4 from the interiorof the car and this air mingledwith the steam will pass through feed conduit 3, the lower end of conduit 13, thence throu h the radiating system 15, the u per'end 0% conduit 13 operatinr to discllfarge vapor -to the atmosphere. When it is desired to utilize the apparatus for ventilating purposes without supplying heatl to the interior. of the car it is only necessary to rotate valve 16 to the position shown in 1 Fig. 3, whereu on the min led steam and air or vapor wi pass direct y through conduit 13 to the atmosphere exteriorly of the car.

It will accordingly be seen that I have l provided apparatus well ada ted to attain among others, all the ends an objects. above enumerated in a simple yet efficient manner.l

One important advantage Yinherent in the apparatus constructed in accordance with the' invention is that a car may be heated and ventilated from the train pipe without the employment 'of any auxiliary devices, and that the steam supplied from the train pipe maybe utilized solely for Ventilating pur- As many changes could oses. p While I have shown the floor of the car equipped at either side with the heating and Ventilating apparatus, it is thought that a description of that employed upon one side thereof will sufhce to impart a clear understanding of the invention.

be made in the above construction and many apparently widely different embodiments of thls invention could be made without departing from the scope thereof, it is intended that .all matter contained in the above description or shown in the accompanying drawings shall beinterpreted as illustrative and ,not in a limiting sense. It is also to be .understood thaty the language used in the following claims is intended to cover all of the generic and s eciiic features of the invention herein described and all statements of thel scope of the invention which, as a matter of language, might be said to fall therebetween.
