Improvements in Gas or Petroleum Engines, especially applicable
to such Engines when Used for the Propulsion of Vehicles, or
in Situations where the Use of Water for Cooling Purposes is
Inconvenient and Cumbersome.
I, HOWARD LANE, of 188, Corporation Street, Birmingham, in the County of
Warwick, Engineer, do hereby declare the nature of this invention to be as
follows:-
Most gas, petroleum, or oil engines, of the internal combustion type, require a
space cr jacket round the working cylinders through which space a certain quantity
of cooling fluid must pass in a given time. This is necessary in order to prevent
the over-heating, jamming, or excessive wear of the cylinders.
My present improvements consist in methods of construction by which air can be
effectually used instead of water or other fluid for cooling the cylinders of such gas
or cil engines. For this purpose instead of the present water space ordinarily used
round the cylinder, I arrange, round the cylinder, a light metallic or other case
perforated in such a way that air entering from the external atmosphere efficiently
strikes and cools the hot cylinder. I increase the surface of the cylinder on which
the air acts by constructing ribs, webs, or vanes of comparative thinness on its
surface. Or I fill the space between the cylinder and the outer case with shavings,
or scraps, of thin metal in such a way that they conduct heat from the cylinder to
the air passing over their surfaces. In order to ensure a sufficient weight of air
passing between the cylinder and its case I employ the induced draught derived
from the exhaust of the engine. By suitably forming the case and adjusting the
nozzle of the exhaust pipe large volumes of air are in this way drawn by inductive
action through the case and considerable cooling effect obtained. The ejected hot
air may be delivered into a suitable chamber or space to deaden the noise of the
exhaust instead of being delivered directly into the atmosphere. Or, instead of
utilizing the exhaust of the engine 1 sometimes obtain a similar effect by the use
of a fan or other apparatus of the ordinary well-known kind for moving large
volumes of air.

I, HOWARD LANE, of 188, Corporation Street, Birmingham, in the County of
Warwick, Engineer, 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, and accompanying drawing, that is to say :-
Most gas, petroleum, or oil engines, of the internal combustion type, require a
space or jacket round the working cylinders through which space a certain quantity
of cooling fluid must pass in a given time. This is necessary in order to prevent
the over-heating, jamming, or excessive wear of the cylinders.

effectually used instead of water or other fluid for cooling the cylinders of such gas
or oil engines. For this purpose instead of the present water space ordinarily used
round the cylinder, I arrange, round the cylinder, a light metallic or other case
perforated in such a way that air entering from the external atmosphere efficiently
strikes and cools the hot cylinder. I increase the surface of the cylinder on which
the air acts by constructing ribs, webs, or vanes, of comparative thinness on its
surface. Or I fill the space between the cylinder and the outer case with shavings,
or scraps, of thin metal in such a way that they conduct heat from the cylinder to
the air passing over their surfaces. In order to ensure a sufficient weight of air
passing between the cylinder and its case 1 employ the induced draught derived
from the exhaust of the engine. By suitably forming the case and adjusting the
nozzle of the exhaust pipe large volumes of air are in this way drawn by inductive
action through the case and considerable cooling effect obtained. The ejected hot
air may be delivered into a suitable chamber or space to deaden the noise of the
exhaust instead of being delivered directly into the atmosphere. Or, instead of
utilizing the exhaust of the engine I sometimes obtain a similar effect by the use of
a fan or other apparatus of the ordinary well-known kind for moving large volumes
of air.
Or, the exhaust may be used in combination with a fan.
The accompanying drawing is in illustration of my invention.
Figure 1 is a side view, partly in section, showing a gas engine, constructed
according to my invention, and fitted with a device for passing air through by
means of the exhaust.
a is the cylinder of the engine, provided with a large number of thin ribs or
gills b, round its surface. c is an outer case perforated at d for the admission of
air, and e is the nozzle of the exhaust from the engine, which by induction causes
air to pass round the cylinder and eject it through the opening f.
Figure 2 shows in plan, and Figure 3 in side view, a modified arrangement in
which a fan is used, instead of a jet. a is the cylinder, b the ribs or gills, c the
outer case perforated at d, g a lan upon the main shaft of the engine (which may
also serve as a flywheel), h the fan case, i a passage for the air from the case c to
the fan which discharges the air at k.
Figure 4 shows in plan an arrangement in which both the exhaust nozzle and a
fan are used, a being the cylinder, the ribs or gills, c the outer case perforated
at d, and e the nozzle for the exhaust, which eject the air along the passage i into
the fan case 1, from which it is discharged by the fan g.

page_text: I do not confine myself to the precise details of construction and arrangement,
which may be varied more or less to suit varying circumstances, but,
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 :-
1. In gas, petroleum, or oil, engines, the method of keeping the cylinder cool by
passing air through a chamber surrounding it, the air being made to pass through
the chamber by the induced draught caused by the exhaust of the engine, or by a
fan or by both methods in combination, substantially as described.
2. In combination with the method of keeping cool the cylinders of gas,
petroleum, or oil, engines described and claimed in Claim 1, the method of
increasing the conducting surface of, or connected with, the cylinder which is to be
cooled, by means of ribs, wehs, or vaues, or metallic shavings or scraps in the
chamber surrounding the cylinder, through which the air is passed, substantially
as described and illustrated.
