JAMES GARNER, 31, Union Street, Tyldesley, near Manchester, Cotton Mill
Manager, do hereby declare the nature of this invention to be as follows:-
-
I make use of the exhaust from a gas or oil engine or similar engine to draw a
current of air through a jacket surrounding the cylinder and thus keep the
cylinder cool without carrying a supply of water. I get the above current of air
very similar to the current of air drawn through the furnace of a locomotive
engine by the exhaust steam going up the funnel.

Cylinder Coner for
I, JAMES GARNER, of 31, Union Street, Tyldesley, near Manchester, in the County
of Lancaster, Cotton Mill Manager, 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:—
This invention relates to the construction of a cylinder cooler for gas, oil, or other
similar engines or motors, such as are used for propelling motor cars and for
other like purposes, the principal objects of the invention being to dispense with
the necessity for carrying a large supply of cold water for the purpose of keeping
the cylinder cool as usually practised.
The nature of my said invention and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference
to the annexed sheet of drawings and the following explanation thereof.
Fig. 1 on the drawings is a vertical section, and Fig. 2 a horizontal section of
the working cylinder of a gas or oil engine or motor showing the application of
my invention thereto.
a is the cylinder which I prefer to make with external radiating flanges or
gills" a for the purpose of increasing the radiating surface thereof; and ba
jacket or casing surrounding the same which is made of thin sheet metal, and is
provided with a conical or trumpet-shaped mouth 6* in front, or facing the
direction in which the vehicle is travelling, for the admission of atmospheric
air, and a smaller conical passage 6** at the rear for the emission or exit of the
same.
c is the exhaust pipe or passage from the working cylinder of the gas, oil or

page_text: other similar engine or motor, the nozzle of which I carry into the interior of the
conical emission or exit pipe 6** above mentioned, the mouth of the exhaust pipe c
being in a backward direction by which means I make use of the exhaust from the
engine or motor to create and draw a current of cold air constantly through the
jacket surrounding the working cylinder a of the engine, in a manner similar
to that whereby a current of air is drawn through the furnace of a locomotive
steam engine by the exhaust discharging through the funnel thereof, and thus the
working cylinder of the gas, oil, or other engine or motor will be kept constantly
cool by the forced draught of air without any necessity for carrying a supply of
water for that purpose.
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:
A cylinder cooler for gas, oil, or similar engines consisting of a jacket or casing
of thin sheet metal or other suitable material surrounding the cylinder, provided
with an open bell, or trumpet-shaped mouth at the front, and with a conical
escape pipe at the rear, into which latter the nozzle of the exhaust pipe or passage
from the working cylinder is carried, and directed rear-wards, so as to create a
forced draught of air through such jacket substantially in the manner and for the
purpose herein before specified and illustrated by the drawings annexed.
Dated this 10th day of December 1898.
