IMPROVEMENTS IN COMPOUND STEAM ENGINES
Year: 1884

page_text: PROVISIONAL SPECIFICATION.
I, THOMAS JAMES TURNER Engineer and Machine Tool Maker of 41 Audley
Street Marsh Lane Bootle in the County of Lancashire do hereby declare the
nature of my invention for "IMPROVEMENTS IN COMPOUND STEAM ENGINES" to
be as follows:-
1st A Heater is placed between High & low pressed Cylinders or in any place so
that the High pressed steam can pass through it to low Pressed Cylinder, at the
same time the water from the feed pump must Pass through it to obtain some heat
from that steam This "Heater" may be made after the surface condensor pattern
that is one or more pipes or tubes inclosed in a casing and are fixed in two tube
plates (one tube plate at each end) and made steam tight, this casing must be
longer in order to leave a cavity at each end when the covers are on.
Now each end has one or more pipes joined thereto, the one end to the High
pressed Exhaust pipe & the other to the Low-pressed Steam pipe.
The casing will have two or more orifices, one or more Jointed to the pipe from
feed pump and one or more to the feed pipe that leads (from the place such
"Heater" is situate) to the boilers.
Another method may be the reverse of the above that is, the steam way (in the
above) may be joined where the feed water pipe is in the above and in that Case
the water way would be through the internal pipe or pipes or tubes.
It may be also done by a jacketed pipe, that is a pipe of any size inclosed in
another pipe so that the outer may contain water & the internal one steam (& vice
versa) being joined to the steam and water pipes respectively as aforementioned
And thus the object would be gained.

page_text: I THOMAS JAMES TURNER Engineer & Machine Tool Maker of 41 Audley
Street Marsh Lane Bootle nr Lpool in the County of Lancashire do hereby declare
the nature of my invention for IMPROVEMENTS IN COMPOUND STEAM ENGINES
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:—
1st A Heater composed of a shell or Cistern containing a pipe or pipes & of such
lengths as may be required for the purpose, the feed water to go through such pipe
or pipes, the Pipe or pipes may be straight or bent in a zig zag or wormlike manner
in order to give the feed water such an amount of travel as to heat it sufficiently
while going through such pipe or pipes & Vice versa that is to say the steam may
go through the said pipe or pipes & the water into the shell or cistern such shell or
Cistern to have a water tight or steam tight cover or man hole for cleaning or other
purpose as the case may be 2nd A Jacketed pipe may be used for the purpose
that is to say the Water go through a pipe having an External one on it having
the steam between the Internal & External pipes or vice versa. 3rd A heater after
the Pattern of a surface condensor having tubes in side and the water may pass
through such tubes & steam in the casing or Steam through the tubes & Water in
the casing.
In each or any one of these three methods of said heater the water is sent through
the heater after such water has passed through the feed Pump & is on its way to
the boiler.
Having now particularly described & ascertained the nature of my said
Invention & in what manner the same is performed I declare what my Claim is
The heating the feed water on its way to the Boiler by means of the Exhaust
Steam of the High pressed Cylinder & before such steam goes into the Low Pressed
steam ways, after leaving the feed pump, in Compound Engines.
Dated this twentieth day of November 1884.
