PROVISIONAL SPECIFICATION.
Improvements in Gas and other such like Engine Cylinders, and in
the Mode and Means for Keeping such Cylinders from Becoming
Unduly Hot.
1, JOHN LEWIS, of Oswald Road, Milverton, Leamington Spa in the County
of Warwick, Timber Merchant, do hereby declare the nature of my said invention to
be as follows:-
My invention has for its object improvements in gas and other such like
cylinders and in the mode and means for keeping such cylinders from becoming
unduly hot which is very necessary in cylinders where high temperature is caused
by the explosion of gas or other products but the invention is of course applicable
to analagous purposes.
I construct my cylinders with an outside jacket which forms a complete chamber
around the cylinder proper or around the vessel or part likely to become unduly
heated. Connected with this chamber at preferably the lower portion I form an
inlet or inlets with a pipe or pipes or passages communicating with cool air which
is either drawn or forced into the chamber so as to envelope the inner cylinder and
from whence it is continuous drawn or driven through another pipe either into the
open air or it may be used for heating or warming purposes so as to produce a
useful effect from the heat. Valves and cocks may be fitted in the passages so as
to regulate the supply and discharge of the air.
Dated this 29th day of January 1896.

Improvements in Gas and other such like Engine Cylinders, and in
the Mode and Means for Keeping such Cylinders from Becoming
Unduly Hot.
I, JOHN LEWIS, of Oswald Road, Milverton, Leamington Spa, in the County
of Warwick, Timber Merchant, do hereby declare the nature of my said invention
and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement :-
My invention has for its object improvements in gas and other such like
cylinders and in the mode and nieans for keeping such cylinders from becoming
unduly hot, which is very necessary in cylinders where high temperature is caused
by the explosion of gas and other products but the invention is of course applicable
to analagous purposes.
I construct my cylinders with an outside jacket which forms a complete chamber
around the cylinder proper or around the vessel or part likely to become unduly
heated. Connected with this chamber at preferably the lower portion I form an
inlet or inlets with a pipe or pipes or passage communicating with cool air which

and from whence it is continuously drawn or driven through another pipe either
into the open air or it may be used for heating or warming purposes, so as to
produce a useful effect from the heat. Valves and cocks may be fitted in the
passages so as to regulate the supply and discharge of the air.
In order that my invention may be clearly understood and more easily carried
into practical effect I have appended hereunto a sheet of drawings upon which
I have given an illustration showing one mode of applying the same and from
which others will without difficulty be able to apply the same to any other con litions
met with in practice.
Figure 1 is a cross section and part sectional inlet pipe E and the outlet B.
The cylinder shown upon the drawings is represented internally by the letter A
and the metal immediately surrounding the bore by a¹ and the metal of the outer
jacket by the letter a. The air space is darkly shaded and is indicated by the
letter a The pipe E which by preference is situated near the bottom of the
cylinder but it may be at the top or other part conveys the current of air from a
blower or other machine in as cool a condition as possible while the pipe B is the
outlet for conveying the air when it has travelled around and about the outside
of the inner chamber away to be used for heating and ventilating or other
purposes as may be desired. The direction of the entrance of the air is also
indicated by the arrow K and the outlet by the arrows 2 and 3. It will however
be obvious that the inlets and outlets may he exchanged the one for the other
with similar effect. As before stated valves or cocks may be fixed in any
convenient positions to regulate the inlet and egress of the air, and the invention
may be applied generally though the principal object is for the purpose of keeping
cool gas and oil engines.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
The improvements in gas or other such like cylinders and in the mode and
means for keeping such cylinders from becoming unduly hot and for utilizing the
exhaust or warmed air as it leaves the said cylinders and which consists essentially
of an outer jacket a enclosing an annular chamber a³ with its inlet and exit
pipes substantially as and for the purpose herein set forth and shown upon the
drawings.
