Year: 1876

page_text: LETTERS PATENT to Alfred Mason, of Bradford, in the County of York,
Secretary of the Saint George's Hall Company Limited, Bradford, and
Advertizing, General, and Insurance Agent, for the Invention of "IMPROVE-
MENTS IN THE METHOD OF AND APPARATUS FOR WARMING RAILWAY CARRIAGES
WITH EXHAUST OR WASTE STEAM FROM THE ENGINE."
PROVISIONAL SPECIFICATION left by the said Alfred Mason at the Office
of the Commissioners of Patents on the 22nd September 1876.
ALFRED MASON, of Bradford, in the County of York, Secretary of the Saint
George's Hall Company Limited, Bradford, and Advertising, General, and Insurance
Agent. "IMPROVEMENTS IN THE METHOD OF AND APPARATUS FOR WARMING
RAILWAY CARRIAGES WITH EXHAUST OR WASTE STEAM FROM THE ENGINE."
"
The object of my Invention is to regulate the temperature of railway carriages
in winter to a more uniform degree of heat, and consequently giving more comfort to
the passengers by utilising the exhaust or waste steam from the locomotive engine.
To dispense with the foot warmers now in ordinary use, and save the expense now
incurred by railway companies in heating the water and labour in filling the foot
warmer with hot water.
I accomplish my object in the following manner :— -With suitable connections to
the blast pipe of the locomotive engine I convey the exhaust or waste steam
through the carriages in pipes arranged under the seats or otherwise as may be
found most advantageous, the outlet of the pipes to be at the rear of the train, the
amount of steam passing through the pipes to give the requisite temperature is
under the control of the guard of the train, and the pipes in the various carriages
are attached together by means of flexible tubes, in order to allow for the varying
distances between the same when starting or stopping the engine.

of an Order of the Lord Chancellor, by the said Alfred Mason in the Great
Seal Patent Office on the 29th March 1877.
ALFRED MASON, of Bradford, in the County of York, Seeretary of the Saint
George's Hall Company Limited, Bradford, and Advertising, General, and Insurance
Agent. "IMPROVEMENTS IN THE METHOD OF AND APPARATUS FOR WARMING
RAILWAY CARRIAGES WITH EXHAUST OR WASTE STEAM FROM THE ENGINE."
The object of my Invention is to regulate the temperature of railway carriages
in winter to a more uniform degree of heat, and consequently giving more comfort
to the passengers by utilising the exhaust or waste steam from the locomotive
engine. To dispense with the foot warmers now in ordinary use, and save the
expense now incurred by railway companies in heating the water and labour in
filling the foot warmers with hot water.
I accomplish my object in the following manner :- -With suitable connections to
the blast pipe of the locomotive engine I convey the exhaust or waste steam
through the carriages in pipes arranged under the seats or otherwise as may be
found most advantageous, the outlet of the pipes to be at the rear of the train, the
amount of steam passing through the pipes to give the requisite temperature is
under the control of the guard of the train, and the pipes in the various carriages
are attached together by means of flexible tubes in order to allow for the varying
distances between the same when starting or stopping the engine.
In order that this Invention may be more fully understood, I herein give
reference to the accompanying Sheet of Drawings illustrating the method I adopt
to collect the steam in the blast or exhaust pipe of the locomotive engine, which is
conveyed in a pipe to the rear of the tender and connected to the carriages by
ordinary unions and flexible tubes not shown in the Drawing, nor are any other
parts of the engine or carriages shown that are not required to elucidate this
Invention.
The same letters refer to the same parts in each Figure.
Fig. 1 is a section of a smoke box of a locomotive engine, the framework of
which is indicated by the letter A; the blast or exhaust pipe B is secured to the
bottom of the smoke box in the usual manner; in the centre or near the centre of
the blast pipe B I form a longitudinal metal partition C which is open at the
bottom end D to the full area of the blast pipe, the top end of the said partition
at E is blank, and is in connection with the sides of the blast pipe B. I connect
the pipe F which is formed with a bell mouth at or near the top of the aforesaid
partition, by which means part of the exhaust steam is conveyed through the said
pipe F which extends to the rear of the tender. In a suitable position in the said
pipe I fix a valve or tap under the control of the engine driver in order that the
passage through the pipe F can be closed and all the exhaust steam will pass away
up the funnel.
In the portion of the blast pipe G that is open to the funnel, I fix a
baffle plate H of such an area that when the same is placed at right angles to the
centre line of the blast pipe there will be a space all round between the edge of the
baffle plate H and the blast pipe for the portion of the exhaust steam to pass away
up the funnel. This baffle plate is centered on a shaft J that passes to the outside of
the smoke box; on the end of this shaft I secure a lever K to which is attached rod L
extending to the foot plate, by which means the baffle plate is under the control of
the driver. M is the ordinary auxiliary blast pipe for assisting the draught when the
engine is standing. The main pipes are fixed under the carriages and are connected
together and to the rear of the tender by means of flexible tubes and unions similar
to those used for connecting fire-hose. The pipes in the carriages are connected to
the main pipe by suitable branches, and are arranged under the seat in the best
practical manner to suit the construction of the carriage. The condensed steam
falls back from the pipes under the seats into the main pipe under the carriages
and is discharged at the rear of the train.
Fig. 2 is a front view of the interior of the smoke box,

page_text: Having thus particularly described my said Invention and the manner in which
the same is or may be performed, I have to state that I do not restrict myself to the
precise details herein described and deliniated, but that what I beleive to be novel
and original, and claim as the Invention secured to me by the herein-before in part
recited Letters Patent is, the arranging and combining of the parts of the blast
pipe and connections to the carriages, substantially as herein-before described.
In witness whereof, I, the said Alfred Mason, have hereunto set my hand
and seal, this Nineteenth day of March, in the year of our Lord One
thousand eight hundred and seventy-seven.
Signed, sealed, and delivered by
the before-named Alfred Mason,
