PROVISIONAL SPECIFICATION.
Improvements in the Construction of Steam and Hot Water Coils or
Radiators and in the Utilization of the same for Warming and
Ventilating.
I WILLIAM GEORGE CANNON of 106 and 107 London Road, Southwark, in the
County of Surrey, Gas and Hot Water Engineer, and Manufacturer of Hot Water
Apparatus, do hereby declare the nature of this invention to be as follows:-
My invention relates to the description of coils or radiators for heating purposes
for which I have obtained Letters Patent dated 29th May 1884 No 8395; and the
object of my present invention is to effect improvements in the utilization of the
same for ventilating purposes and in the method of forming the junctions, and to
afford increased facilities for erecting and detaching the tubes making good the
joints, and otherwise manipulating the same.
Whereas in my said former Specification the pipes are described as arranged with
vertical openings at each end and horizontal faces to the junctions, the vertical pipes
being united to the horizontal pipes by means of through bolts and nuts. My present
invention consists in forming such junctions at the sides of the pipes instead of
their ends the two ends being closed and the faces of the openings being vertical.
Suitable sockets are cast upon the faces of the main casting forming the horizontal
pipes and corresponding flanges or rings or other suitable provisions are made upon
the vertical pipes, round which the elastic washers are placed, to secure fluid tight
Joints.
The pipes are united to the main casting, by means of bolts, screws, studs and
nuts clips, lugs, or equivalent means, the joint being made good by means of rubber,
asbestos, woodite, or other suitable rings, washers or packing. The main casting
may be fitted with single, double, treble, or other sets or groups of vertical pipes
either on one side or on both sides of the main casting; special provision being made
in the main casting and in or upon the detachable pipes, to receive the bolts, screws,
studs or nuts and washers, clips, lugs, or equivalent devices as required.
By the aforesaid arrangements I am enabled to remove and refix any one or more
of the vertical pipes, without disturbing any of the others, or the main casting
itself.
The lower part of the main casting is preferably made with chambers to admit the
external air, by means of suitable junctions, such air rising through suitable openings
to the vertical pipes and being thereby warmed before it mixes with that in the
apartment.
My invention may be used with either steam or water, and, when water is
used, plugs or taps are fitted to the main casting to permit the escape of air,
when filling the apparatus with water.
I also sometimes combine with my present invention, the improvements for
which I have obtained Letters Patent No. 7131 dated June 10th 1885
Dated 8th May 1880

Improvements in the Construction of Steam and Hot Water Coils or
Radiators and in the Utilization of the same for Warming and
Ventilating.
I, WILLIAM GEORGE CANNON, of 106 and 107 London Road Southwark in the.
County of Surrey, Gas and Hot Water Engineer, and Manufacturer of Hot Water
Apparatus, 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 heating purposes
for which I have obtained Letters Patent dated 29th May 1884 No 8395, and
the object of my present invention is to effect improvements in the utilization of the
same for ventilating purposes and in the method of forming the junctions, and to
afford increased facilities for erecting and attaching and detaching the tubes, making
good the joints and otherwise manipulating the same.
Whereas in my said former specification the pipes are described as arranged with
vertical openings at each end and horizontal faces to the junctions, the vertical pipes
being united to the horizontal pipes by means of through bolts and nuts. My present
invention consists in forming such junctions at the sides of the pipes instead of their
ends, the two ends being closed and the faces of the openings being vertical Suitable
sockets are cast upon the faces of the lower main casting and upper horizontal pipes, and
corresponding flanges or rings or other suitable provisions, are made upon the vertical
pipes, round which the elastic washers are placed, to secure fluid tight joints. Or I
may form such joints of flat surfaces, with planed faces, metal and metal, or by
equivalent means.
The pipes are united to the main casting by means of bolts, screws, studs and
nuts, clips, lugs, or equivalent means, the joints being made good by rubber,
asbestos, woodite, or other suitable rings, washers or packing, red lead, gasket, or
otherwise as aforesaid. The main casting may be fitted with single, double, treble, or
other sets or groups of vertical pipes, either on one side or on both sides; special
provision being made in the main casting, and in or upon the detachable pipes, to
receive the bolts, screws, studs or nuts, and washers, clips, lugs, or equivalent devices,
as required.
By means of the aforesaid arrangements I am enabled to remove and refix any
one or more of the vertical pipes, without disturbing any of the others, or the main
casting itself.
The main casting is preferably fitted with chambers to admit the external air, by
means of suitable junctions, such air rising through suitable openings to the vertical
pipes, and being thereby warmed before it mixes with that in the apartment.
My invention may be used with either steam or water, and, when water is used
plugs, syphons, automatic vents or taps are fitted to the main casting to permit the
escape of air, when filling the apparatus with water.
And in order that my said invention may be particularly described and ascertained
reference is hereby made to the accompanying drawings, in which similar letters of
reference indicate corresponding parts.
Fig. 1 is a front elevation of a radiator. Fig. 2 is a sectional elevation, showing
the method of fitting a row of pipes on one side only of the main casting. Fig. 3 1s
a sectional elevation showing the method of fitting sets of vertical pipes on both
sides of the main casting; and Fig. 4 is a horizontal section on the line of
Fig. 3.
Referring to Figs. 1 and 2, a is the main casting. a¹ is a longitudinal channel
forming part of the main casting, and operating as a horizontal pipe in connection
with the vertical pipes d d. The vertical face of the wall of the horizontal pipe a¹
is shown formed with openings and sockets to receive the collars cast on the lower
ends of the pipes d d. These junctions are secured by screws e e, as shown in Fig. 2,

page_text: Packing rings may be used to render the junctions water and steam tight. b is the
casting to which the upper ends of the pipes d d are secured by means of screws ff
(Fig. 1) passing through ears formed upon the pipes dd for that purpose. This
casting forms a longitudinal channel, in communication with the upper ends of the
pipes, the joints being also shown constructed for packing rings.
ccaro the circulating pipes, in communication with any suitable boiler or other
heating apparatus. 9 is an ornamental cover laid upon the apparatus, under which
plugs, syphons, automatic vents or taps may be fitted to let off steam or air, or to
ascertain when the radiator is filled with water.
I sometimes fit the radiator so as to admit fresh air from the outside of the house
by a pipe
passing through the wall k. The air is thus led into an enclosed
chamber m, extending the whole length of the radiator, and closed at the ends. From
the chamber m the air passes into the chamber n, also closed at the ends. The incoming
air passes from the chamber n between the pipes d d, as indicated by the arrows;
whereby fresh warm air may be admitted to the apartment.
Referring to Figs 3 and 4 (of which Fig. 1 is a front elevation) the channels a'
and b are formed to receive sets of pipes dd on both sides, each set of pipes being
secured in a similar manner to that shown in Fig. 2 This form and arrangement of
my invention may also be fitted with air chambers m n as shown in Fig. 2.
Although I have shown the pipes cast in sets of three, communicating at each
end, I do not confine myself to that or any number, as it is obvious that the number
may be varied, and other sectional forms may be used
I sometimes combine with my present invention, the improvements for which I
have obtained Letters Patent No. 7131, dated June 10th 1885, by the addition of the
boiler, as therein described.
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 steam and hot water coils or radiators of the description aforesaid, the
improved construction of pipes whereby the junctions are made vertical for the
purpose of facilitating the setting up, removal or renewal of one or more vertical pipe
or pipes, without disturbing the remainder substantially as described and illustrated
by the drawings.
2. In combination with steam and hot water coils or radiators of the description
aforesaid, the improved construction of air chambers, whereby fresh air is introduced
to the apartment and warmed by contact with the heated pipes substantially as
described, and illustrated by the drawings
3. The general construction, combination and arrangement of the several and
respective parts, together constituting my improvements in the construction of steam
and hot water coils or radiators, and in the utilization of the same for warming
and ventilating, substantially as hereinbefore described and illustrated by the
drawings.
