IMPROVEMENTS IN GAS MOTOR ENGINES
Year: 1884

page_text: PROVISIONAL SPECIFICATION.
I. CHARLES HENRY ANDREW of the firm of Messieurs J. E. H. Andrew and
Company, Engineers of Waterloo Road, Stockport, Cheshire do hereby declare
the nature of said Invention for IMPROVEMENTS IN GAS MOTOR ENGINES to be
as follows:-
My invention relates to Gas Motor Engines operated by the combustion of
mixed charges of combustible gas and atmospheric air. It frequently occurs that
the waste heat emitted from the cylinder of an engine of large power proves an
element of danger in buildings by overheating the exhaust chamber or chambers
and pipes attached; the object of my invention is to avoid this danger.
To effect this I purpose constructing the exhaust chamber or chambers, and the
exhaust pipes with water jackets surrounding them.
The water within these jackets will be made to circulate, and the heat therefrom
may be utilized for warming rooms or for other purposes.
The water circulation may be effected from the same source as that which causes
the circulation through the jacket of the engine cylinder or from an independent
Bource,
CHARLES HENRY ANDREW.

DE POLICATION.
'
I CHARLES HENRY ANDREW, of the firm of Messieurs J. E. H. Andrew and
Company, Engineers, of Waterloo Road Stockport, Cheshire, do hereby declare the
naturo of said Invention for IMPROVEMENTS IN GAS MOTOR ENGINES, and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :—
My invention relates to gas engines operated by the combustion of mixed
charges of combustible gas and atmospheric air.
It frequently occurs that the waste heat emitted from the cylinder of an engine
of large power proves an element of danger in buildings by over heating the
exhaust chamber or chambers and pipes attached; the object of my Invention is
to avoid this danger.
To effect this I purpose constructing the exhaust chamber or chambers, and the
exhaust pipes with water jackets surrounding them. The water within these
jackets will be made to circulate and the heat therefrom may be utilized for
warming rooms or for other purposes.
The water circulation may be effected from the same source as that which causes
the circulation through the jacket of the engine cylinder or from an independent
source.
And in order that my Invention may be fully understood and readily carried
into effect I will describe the accompanying Drawing which illustrates the manner
of applying my Invention to the exhaust passages and exhaust chamber of a gas
motor engine.
In this Drawing, a is the cylinder of the gas motor engine; b the exhaust
passage leading into the exhaust chamber c and 6¹ the exhaust passage lending out
of the chamber c; d is the water jacket which surrounds the cylinder a, as usual,
and is also (as shown) extended according to my Invention so as to enclose the
exhaust passages b 6¹ and the exhaust chamber c.
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
The use and application of a water jacket or water jackets to the exhaust
passages and exhaust chamber or chambers of a gas motor engine, substantially as
and for the purposes herein described and as illustrated by the Drawing annexed.
Dated this 23rd day of June 1885.
