Improvements in or relating to the Cooling of Cylinders of Explosion
Engines.
I, EDWARD JOEL PENNINGTON, of The Motor Mills, Coventry, in the County of
Warwick, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to the cooling of the cylinders of explosion engines,
and may be carried out in the following manner:-
I provide the cylinder externally with radiating plates or gills so arranged in a
conical or tapering manner that the first plates to receive the impact of the air
are of less size than the later ones, so that the air may impinge upon all the plates
successively, and not merely rebound from the first and miss the rest.
The plates
thus arranged may be used simply as above described or they may be in con-
junction with an external casing or shield or a series thereof for the purpose of
directing the current of air so as to increase its effect; such a casing would by
preference lie at a suitable distance beyond the gills so as to allow of a sufficiently
free passage of air. The gills may either be formed in a piece with the cylinder
or they may be separate and attached to it. The gills may be formed with their
outer edges turned over in the direction to meet the air current so as to facilitate
the access of the air amongst the gills as much as possible. The largest gills may
be at either end of the cylinder according to the use direction of the air current
which is always intended to be faced by the smallest gills.
In some cases it is desirable to make the gills separate from the cylinder and
attach them thereto by suitable means; this is particularly convenient when the
cylinders are made of simple steel tubes turned up so that the gills cannot con-
veniently be formed out of the same piece of metal as the cylinder.
Where separate gills are employed they may be formed, each gill separate from
its neighbours, and provided with a suitable flange which can be bolted or otherwise
secured to the cylinder-for example each gill could be made out of a piece of angle
or T section metal, curved to fit the cylinder either as a complete ring or in more
than one piece. Or again, the gills may be cast complete with a suitable flange or
fastening device, say in two halves or even as a complete tube to fit outside the
cylinder, but as this would tend to retain the heat I prefer to make the gills or
their fastenings in skeleton form and attach them to the cylinder in the simplest
manner. The gills may be made of ductile metal such for example as aluminium
so that they can be easily bent to fit the cylinder, and they or their flanges may be
run into dovetail grooves formed in or upon the cylinder.

I, EDWARD JOEL PENNINGTON, of The Motor Mills, Coventry, 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:
This invention relates to the cooling of the cylinders of explosion engines and
may be carried out in the following manner:-
I provide the cylinder externally with detachable radiating plates or gills of
which the accompanying drawing is a perspective view partly broken away show.
ing four of the detachable gills in place upon the cylinder of an engine.
Each gill A is shown separate from its neighbours and is either a complete ring
or divided into two parts as shown in the drawings. Or the gills may be all cast
or otherwise formed together and held to the cylinder together. A flange B is
provided and lugs C are formed on each half of the gill so that the two parts may
be clamped around the cylinder by screws D, the position of the cylinder being
indicated in the drawing by dotted lines.
The gills may be made of ductile metal such for example as aluminium or gun
metal so that they can be easily bent to fit the cylinder and they or their flanges
may be run into dove-tail grooves formed in or upon the cylinder.
If desired the flanges B may be bolted direct to the cylinder, or other means than
those shown may be employed for detachably fixing the gills upon the cylinder.
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:-
..
1. A detachable plate or gill substantially as and for the purpose described.
2. The combination with an explosion engine cylinder of detachable plates or
gills substantially as and for the purpose described.
