This invention relates to a new and improved
vapor heating system, more especially to‘ a heat
ing system oi'the steam ‘or vapor type particu
larly adapted for heating passenger railway cars‘.
It is customary in such railway car heating sys
tems to provide radiating pipe loops which ex
tend longitudinally of the car near the floor line
either adjacent to or ‘within the side wall of the
car. The i‘iow'of heating ?uid into and through

on the line 5-5‘ of Fig. 4.

Referring ?rst to Fig. l, at A is diagrammati
callyv illustrated the outlines of a railway car,
preferablyoi' the Pullman type. . In the example 5
here'shown this car is provided with a central
aisle B and is divided into. a plurality of separate
spaces to be heated, indicated at C, C20". etc.

The principal object of this invention is to
provide an improved heating system of the type
brie?y described hereinabove and disclosed more
30 in detail in the speci?cations which follow. I
Another object is to provide a vapor heating

car or space to be heated can bermanually se

Another object is to provide an improved type
of ‘concealed radiation for railway cars.
Another object is to provide an improved di
recting valve for heating systems.
40 Other objects and advantages of this inven
tion will be more apparent from the following
detailed description of one approved form ofap

principles of this invention. '
