PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Heating Railway Trains.
I, JOHN ELIOT HOWARD, of Coomb's Wood Tube Works, Halesowen, near
Birmingham, Manufacturer do hereby declare the nature of this invention to be as
follows:-
In many cases it is desirable that the couplings between the steam pipes of two
adjacent carriages should be above the pipes themselves.
According to this invention each steam pipe leads at the two ends of the carriage
into the lower end of the vertical branch of a swan neck pipe, the other end of the
swan neck receiving the flexible coupling and at the junction of the steam pipe and
swan neck I place a cock. In the surface of the plug of this cock there are four
openings, three of them being 90 degrees apart and connected by a T shapel
passage of the full size of the steam pipe whilst the other is about 45° degrees
from one of the two diametrically opposite openings (that is those at the ends of
the head of the T) and is connected to the main passage by a comparatively small
passage.
The shell of the cock has three openings one at the side connected to the end of
the steam pipe, one at the top connected to the lower end of the upright branch of
the swan neck and the third at the bottom leading to the air.
When the steam pipes are in use the plugs of all the cocks between the carriages
are turned so that the one end of the head of the T opens into the steam pipe and
the end of the stem into the swan neck the other two openings being closed but the
plug of the cock at the rear end of the last carriage is turned so that the small
passage opens into the steam pipe allowing a small jet of steam to escape and
ensure a flow of steam through the train. When the apparatus is not in use the
stem of the T is directed to the steam pipe and the ends of the head to the swan
neck and air respectively so that the whole system is free to drain.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Heating Railway Trains.,
I, JOHN ELIOT HOWARD, of Coomb's Wood Tube Works, Halesowen, near
Birmingham, Manufacturer, do hereby declare the nature of this invention and
in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
-
In many cases it is desirable that the couplings between the steam pipes of two
adjacent carriages should be above the pipes themselves.
and 3 of the drawings
According to this invention each steam pipe a Figures 1,
leads at the two ends of the carriage into the lower end of the vertical branch of
a swan neck pipe b, the other end of the swan neck receiving the flexible coupling c
and at the junction of the steam pipe and swan neck I place a cock. In the
surface of the plug d of this cock there are four openings d', d' d' d' three of them
viz.: d' d d being 90 degrees apart and connected by a T shaped passage of the
full size of the steam pipe whilst the other d' is about 45 degrees from d¹ one of
the two diametrically opposite openings (that is those at the ends of the head of
the T) and is connected to the main passage by a comparatively small passage.
The shell e of the cock has three openings eles e³, el being at the side and
connected to the end of the steam pipe a, e³ being at the top and connected to the

page_text: lower end of the upright branch of the swan neck 6 and e* being at the bottom anʼl
leading to the air.
When the steam pipes are in use the plugs of all the cocks between the carriages
are turned as shown in Figure 1 so that the end of the head of the T opens into the
steam pipe a and the end d² of the stem into the swan neck b, the other two
openings being closed but the plug of the cock at the rear end of the last
carriage is turned as shown in Figure 2 so that the small passage opens into the
steam pipe a allowing a small jet of steam to escape and ensure a flow of steam
through the train. When the apparatus is not in use the stem 2 of the T is as
shown in Figure 3 directed to the steam pipe a and the ends d' d' of the head to
the swan neck and air respectively so that the whole system is free to drain.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is :-
1. In apparatus for heating railway trains the combination of a steam pipe, a
coupling pipe and a cock such that the two pipes can be connected together and
communication between them and the air closed, or the connecting pipe can be fully
opened to the air and the steam pipe partially opened to the air or the two pipes
can be both fully opened to the air substantially as described.
2. Apparatus for heating railway trains substantially as described and shown in
the drawings.
