PROVISIONAL SPECIFICATION.
Improvements in or relating to Radiating Devices for Heating or
Cooling Purposes.
I, ROBERT CHARLES AYTON, Engineer, of 5, Richmond Terrace, Cox Street,
Coventry, in the County of Warwick, do hereby declare the nature of this inven-
tion to be as follows; -
This invention relates to radiating devices for heating or cooling purposes.
According to this invention I provide the tube, cylinder or other body from
which heat is to be radiated with a partial or total covering constructed of a metal
having a higher conductivity than the metal of which the tube or cylinder itself
is composed. Thus in applying the invention to the cylinder of an internal com-
bustion engine the cylinder may be provided with a conductive covering or with
wings or gills constructed of aluminium, silver or some alloy of these or other
metals, whose heat conductivity is considerably greater than that of the iron or
steel of which the cylinder is composed.
The conductive covering may be plain, corrugated, or provided with wings or
gills or the latter may be applied to the cylinder, tube or other body separately,
or in groups, or the covering may be given any shape suitable for increasing the
radiating surface of the tube or cylinder which is presented to the air or sur-
rounding fluid.
It is of course necessary that the conductive covering should be applied to the
radiating body in such a way as to ensure intimate contact between the metals
of which the body and covering are composed.
In providing the cylinder of an internal combustion engine with a conductive
covering constructed in accordance with this invention the following method may
be conveniently employed;-
The exterior of the cylinder is tapered for the whole or part of its length, the
interior of the covering, which may conveniently be in the form of a jacket or
sleeve with gills cast upon it, being correspondingly tapered internally.
The covering is now applied to the exterior of the cylinder and forced into
place by some convenient means such as hydraulic pressure. The cylinder is
preferably provided with a flange at one end against which the covering is forced,
a lock nut upon the other end of the cylinder retaining the conductive covering
after it has been forced into place.
If desired the covering may be simply shrunk or cast on or other devices
employed for suitably applying it to the part radiating heat.
It will be understood that the above invention is equally applicable in the con-
struction of condenser tubes or radiators such as are employed for heating or
cooling purposes.

I, ROBERT CHARLES AYTON, of 5, Richmond Terrace, Cox Street, 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 radiating devices for heating or cooling purposes.
According to this invention I provide the tube, cylinder, or other body from
which heat is to be radiated, with a partial or total covering constructed of a metal
having a higher conductivity than the metal of which the tube or cylinder itself
is composed. Thus in applying the invention to the cylinder of an internal com-
bustion engine, the cylinder may be provided with a conductive covering or with
wings or gills constructed of aluminium, silver or some alloy of these or other
metals, whose heat conductivity is considerably greater than that of the iron.or
steel of which the cylinder is composed.
The conductive covering may be plain, corrugated, or provided with wings or
gills, or the latter may be applied to the cylinder, tube or other body separately
or in groups, or the covering may be given any shape suitable for increasing the
radiating surface of the tube or cylinder which is presented to the air or sur-
rounding fluid.
It is of course necessary that the conductive covering should be applied to the
radiating body in such a way as to ensure intimate contact between the metals
of which the body and covering are composed.
The accompanying drawing illustrates in longitudinal section a portion of the
cylinder of an internal combustion engine with radiating gills fitted in accordance
with this invention.
The gills A which may be of any convenient form are made of, some metal
having a higher conductivity than the metal of which the cylinder B is composed.
In order to ensure intimate contact between the metals it is preferable to cast
the gills in position upon the cylinder, but other methods of placing the latter
in position may be employed, thus, for example, the exterior of the cylinder may
be tapered and the interior of the radiating covering being correspondingly
shaped, or the radiating covering may be simply shrunk into place, the method
of applying the covering varying in accordance with the body to which it is to be
applied.
It will be understood that the invention is equally applicable in the construc-
tion of condenser tubes or radiators such as are employed for heating or cooling
purposes.
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. The combination with a body radiating heat of a conductive covering formed
of a metal having a higher conductivity than the metal of which the radiating
body is composed.
2. The combination with a body radiating heat of radiating gills formed of a
metal having a higher conductivity than the metal of which the radiating body is
composed.

of a metal having a higher conductivity than the metal of which the body is
composed and cast in position upon the body.
