PROVISIONAL SPECIFICATION.
Improvements in the Construction of Steam and Hot Water Coils
or Radiators, and in the Utilisation of the same for Warming,
Ventilating, and Cooling.
1, WILLIAM GEORGE CANNON, of 110 London Road, Southwark, London
S.E., Gas, Steam, Hot Water, and Electrical Engineer, do hereby declare the
nature of my said invention to be as follows:-
My invention relates to the description of coils or radiators for which I have
obtained Letters Patent dated 29th May 1884, No. 8395; 11th June 1885,
No. 7131; and 8th May 1889, No. 7684; and the object of my present invention
is to effect further iniprovements in the construction of such coils, and in arranging
the same for the purposes aforesaid.
In carrying out my present invention, I form the coils of solid-drawn or other
tubes, of steel, copper, brass, or other suitable metal, or combination of metals. The
coils are bent into spiral forms, each end of the coils being united to horizontal
pipes by any of the methods and means described in my said former Specifications,
or by screw-joints, union joints, expanding joints, or otherwise.
The coils may consist of single or multiple pipes in groups, rows, or otherwise;
and entirely open and exposed for warming or cooling, or enclosed in suitable
casing for promoting ventilation also.
The case in which the coils are enclosed for purposes of ventilation, is fitted in
and passed
such a manner that air may be drawn thereinto from an external source,
out from thence into the room, so as to admit fresh warın air thereinto; or the air
may be admitted to and delivered from the casing directly from and to the room
or other space in which it is fitted.
The coils may be supplied with heated water, steain, or other fluid, and may be
heated by gas, oil lamps, connections with steam or other boilers, or otherwise.
When used for cooling, the coils may be supplied with brine, iced water, or any
suitable fluid for the purpose.
I sometimes fit, inside the coils, a series of metal plates, formed in radiating or
other sections. These plates preferably touch the coils at a number of points, and
become heated thereby, thus materially increasing the heating surface in contact
with the circulating air, and also assisting in dispersing the fresh air, as it passes
from the base to the upper exits, and adding caloric thereto.

I, WILLIAM GEORGE CANNON, late of 110, but now of 107 London Road,
Southwark, London S.E., Gas, Steam, Hot Water, and Electrical Engineer, 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 relates to the description of coils or radiators for which I have
obtained Letters Patent dated 29th May 1884, No. 8395; 11th June 1885.
No. 7131 and 8th May 1889, No. 7684; and the object of my present invention
is to effect further improvements in the construction of such coils, and in arranging
the same for the purposes aforesaid.
;
According to my present invention, I form the coils of solid-drawn or other
tubes, of steel, copper, brass, or other suitable metal, or combination of metals.
The coils are bent into spiral forms, each end of the coils being united to
horizontal pipes by any of the methods and means described in my said former
Specifications; or by strew joints, union joints, expanding joints, or otherwise.
The coils may consist of single or multiple pipes in groups, rows, or otherwise;
and entirely open and exposed for warming or cooling, or enclosed in suitable
casing for promoting ventilation also.
The case in which the coils are enclosed for purposes of ventilation, is fitted in
such a manner that air may be drawn thereinto from an external source, and passed
out from thence into the room, so as to admit fresh warm air thereinto; or the air
may be admitted to and delivered from the casing directly from and to the room or
other space in which it is fitted.
The coils may be supplied with beated water, high or low pressure steam, or
other fluid, and may be heated by gas, oil lamps, connections with steam or other
boilers, or otherwise.
When used for cooling, the coils may be supplied with brine, iced water, or any
suitable fluid for the purpose.
I sometimes fit, inside the coils, a series of metal plates, formed in radiating or
other sections. These plates preferably touch the coils at a number of points, and
become heated thereby, thus materially increasing the heating surface in contact
with the circulating air, and also assisting in dispersing the fresh air, as it passes
from the base to the upper coils, and adding caloric thereto.
And in order that my said invention, may be particularly described and
ascertained, reference is hereby made to the accompanying drawings, in which
similar figures of reference indicate corresponding parts.
Fig. I is an elevation showing one method of carrying out my invention, in which
a row of coils is fitted, without being enclosed in a case, the air having free access
thereto in all directions.
Fig. 2 is an elevation of a suitable case for enclosing the coils and directing the
currents of air for warming and ventilation.
Fig. 3 is a transverse section of Fig. 2, showing the coils in position, and a
method of admitting air from the outside of a building, and shutting off the same,
as required.
Fig. 4 represents a circular radiator case, for a single or double spiral coil,
forming a fresh air chamber.
Fig. 5 is a plan of the cover to Fig. 1, which may be a slab of marble or other
material, to form a shelf or sideboard.

page_text: Fig. 6 is a plan of the cover of Fig. 2, with ventilating openings.
Fig. 7 is a plan view of the cover of Fig. 4.
Fig. 8 is a horizontal view of the pipe connections.
The tubular coils 10 are connected at their top and bottom ends with horizontal
pipes 11, as shown, the pipes 11 being charged with steam or other suitable fluid,
in the usual manner. In some cases I also fit vertical plates 12, the plates being
in contact with the coils at a number of points, as shown in Fig. 8 and by dotted
lines in Fig. 1. These plates increase the heating surface in contact with the air,
and also assist in dispersing the air. The case 13, shown in Figs. 2 and 3, for
enclosing the tubes, is suitable for directing and controlling the currents of air.
When placed against a wall 14, as shown in Fig. 3, fresh air may be admitted
through the passage 15, which may he opened and closed by means of the
handle 16. The passage 17 being closed while the passage 15 is open. The fresh air
entering from the outside passes upwards, receiving heat by contact with the tubes,
and the heated air passes into the apartment through the upper plate 18. By
closing the passage 15 and opening the passage 17, the entering air may be drawn
from the apartment, instead of from the outside.
When a single coil is used for heating an apartment, it is preferably supplied
with high pressure steam and placed in a case 19, as shown in Fig. 4, to prevent
accidental personal contact with the surfaces of the tubes.
Double coils are sometimes fitted one inside the other for increasing and
concentrating the heating surface.
Having now particularly described and ascertained the nature of my said inveu-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The improvements in the construction of steam and hot water coils or
radiators, and in the utilisation of the same for warming, ventilating and cooling,
substantially as herein before described and illustrated by the drawings.
2. In combination with tubular heating coils as aforesaid, the application and
use of vertical contact plates 12, for the purpose of increasing the heating surface
in contact with the air, substantially as herein before described and illustrated by
Fig. 8 of the drawings.
3. In coils for the purposes aforesaid, the application and use of solid drawn
tubes, substantially as described.
4. In apparatus as aforesaid the combination therewith of cases arranged and
operating so as to control the direction of the currents of air, substantially as herein
before described and illustrated by the drawings.
Dated 11th February 1895.
