PROVISIONAL SPECIFICATION.
An Exhaustless Steam Engine.
WILLIAM SCORER Engine Man Double Row Harton Colliery Durham. I do
hereby declare the nature of this invention to be as follows:-
I return the whole of the exhaust steam from the cylinder back to the boiler by
the following means. I condense the exhaust steam by means of small vessels
fixed to suitable pipes placed between the cylinder and exhaust valve. I next pass
water taken from the coldest part of the boiler (which water may be passed
through cooling chambers if necessary) and inject the said water into the said
small vessels, the water comes into contact with the spent steam, and so far reduces
the indicated heat, as to make it easy to force the said spent steam back into the
boiler through pipes which are connected to the boiler and engine for the purpose.
I use the cushion caused at the end of the stroke of the piston for the purpose of
driving the spent steam and the water used for condeusing the same, back into the
boiler. Suitable cocks or valves are fixed to the said pipes connecting the boiler
and engine. These cocks or valves are made to open and shut so as to allow the
passage of the exhaust steam and water back into the boiler at suitable intervals.
By the means above described the steam will be made to pass from boiler to
engine and engine to boiler.

COMPLETE SPECIFICATION.
An Exhaustless Steam Engine.
WILLIAM SCORER, Engine Man, Double Row, Harton Colliery, South Shields.
I 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:-
I return the whole of the exhaust steam from the cylinder back to the boiler by
the following means. I condense the exhaust steam by means of small vessels
fixed to suitable pipes placed between the cylinder and exhaust valve. I next pass
water taken from the coldest part of the boiler (which water may be passed through
cooling chambers if necessary) and inject the said water into the said small vessels;
the water comes into contact with the spent steam and so far reduces the indicated
heat as to make it easy to force the said spent steam back into the boiler through
pipes which are connected to the boiler and engine for this purpose.
I use the
cushion caused at the end of the stroke of the pistons for the purpose of driving
the spent steam and the water used for condensing the same back into the boiler.
Suitable cocks or valves are fixed to the said pipes connecting the boiler and
engine; these cocks or valves are made to open and shut so as to allow the passage
of the exhaust steam and water back into the boiler at suitable intervals. By the
means above described the steam will be made to pass from boiler to engine and
engine to boiler.
The accompanying drawing will make my invention quite clear.
B is the boiler.
S.P is the steam pipe to cylinder.

E.V- -are the exhaust valves from cylinder to boiler.
E.P is the exhaust pipe to boiler.
C.P is the water pipe from the coldest part of boiler to injection cocks.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, 1 declare that what I
claim is:
(1) Injecting the condensing water into the space immediately between the
cylinder and the exhaust valve by which means the condensing water and the
exhaust steam is brought into direct contact during the period of exhaustion
whereby the indicated temperature ranges from a low degree to the boiler heat
during the exhaust, at which heat it is ejected through the self-acting exhaust
valve into the boiler again.
(2) That by this means "An exhaustless steam-engine" has been discovered
and invented.
