PROVISIONAL SPECIFICATION.
We, SMITH FEATHER of 17 Wade Street, Bradford Wool Stapler, and ROBERT
SHACKLETON of North Wing Mills, Bradford, Paper Manufacturer, in the County
of York do hereby declare the nature of our invention for IMPROVED MEANS
FOR DISPOSING OF AND UTILIZING THE EXHAUST STEAM IN TRAMWAY ENGINES.
to be as follows:-
This invention relates to certain improvements in Engines used for Tramway
purposes especially of the type in which no condensers are used. Hitherto the
steam from the Exhaust has been passed into a superheater or really a destructor
in order to comply with a regulation of the Board of Trade as to the non emission
of steam from the Engine.
In our improvement the exhaust steam is carried from the exhaust and passed
into a tank having a series of pipes or one continuous coil of pipes through which
the feed water is passed to the boiler: we can pass the steam through the pipes
and have the feed water surround the same or can take part of the exhaust and
bring the same into contact with the feed water in the ordinary tank. In any
case we utilize the exhaust in this class of Engine for the purpose of raising the
temperature of the feed water and thereby effect a more economical working of
such Engines and pass less steam into the Destructor and thereby further insure
the efficient carrying out of the aforesaid regulation of the Board of Trade.
Dated this 6th day of September 1884.

We, SMITH FEATHER, of 17, Wade Street, Bradford, Wool Stapler; and ROBERT
SHACKLETON, of North Wing Mills, Bradford, Paper Manufacturer in the County
of York, do hereby declare the nature of our invention, for "IMPROVED MEANS
FOR DISPOSING OF AND UTILIZING THE EXHAUST STEAM IN TRAMWAY ENGINES,"
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
Hitherto steam
This invention relates to certain improvements in engines used for tramway
purposes, especially of the type in which no condensers are used.
from the exhaust has been passed into a superheater or destructor, in order to
coinply with a regulation of the Board of Trade, as to the non-emission of steam
from the engine.
In our improvement, the exhaust steam is conveyed by pipes from the cylinders,
into a tank having a series of pipes or one continuous coil of pipes, through which
the feed water is passed to the boiler; or the steam may be passed through the
pipes and the feed water surround the same, or a portion of the exhaust steam may
be brought into direct contact with the feed water in the ordinary store tank. By
any of these arrangements, we utilize the exhaust steam in this class of engine for
the purpose of raising the temperature of the feed water, and thereby effect a more
economical working of such engines, and pass less steam into the superheater or
destructor, thus further ensuring the efficient carrying out of the aforesaid
regulation of the Board of Trade.
In the accompanying drawings, Fig 1. represents the outline of a tramway
engine without condenser, and fitted with our improved feed water heating
apparatus. Fig 2 is an enlarged detail plan with the cover removed for shewing
the heating pipes, and Fig 3 is a cross section through the same.
The engine is constructed in the usual manner, but instead of connecting the
exhaust side of each cylinder A, and its respective receiver B, with a direct exhaust
pipe C, we form a branch in some portion of the saine, and secure thereto branch
exhaust pipes D, which are also connected to the tank E, placed upon the ordinary
store tank F. The interior of tank E; is fitted with a series of pipes G, connected
to the feed pump or injector by pipes G₁, and to the boiler by outlet pipes G2, both
inlet and outlet pipes being arranged with the ordinary check and other valves or
taps.
By the pipes D, charging the tank E with exhaust steam, and the water passing
through the same in pipes G, it is heated before entering the boiler; thereby
utilizing the heat in the exhaust steam for raising the temperature of the feed
water, by which a corresponding saving in fuel is effected. By opening the tap H,
any accumulation of water in the bottom of tank E, formed by the condensation of
the exhaust steam, is allowed to run into the store tank F below.
The exhaust steam may be utilized by passing it through the pipes G, and filling
the tank E with water; or steam may be taken into the store tank F and thereby
accomplish our object of heating the feed water; by which the engines are more

page_text: economical in the consumption of fuel, and a reduction in the quantity of steam
to be dealt with by the superheater or destructor is effected; thereby further
ensuring the efficient carrying out of the regulations of the Board of Trade.
The foregoing part of the specification describes our invention as applied to
tramway engines without condensers; but we wish it to be understood that our
apparatus may also be applied to engines having condensers, in which case we
conduct the exhaust steam to the tank E, or through the pipe G, in the same
manner as before described; the remainder of the exhaust steam going to the
condenser which may be of the ordinary construction.
Having now particularly described and ascertained the nature of our said
invention, and in what mauner the same is to be performed, we declare that what
we claim is,
Heating the feed water on tramway engines by the exhaust steam, substantially
in the manner as hereinbefore described.
