Improvements in "Radiators" for Heating and Ventilation.
J, CHARLES JAMES APPLEBY of 22 Walbrook, in the City of London Civil
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, communicated to me from abroad, by Jules Defontaine,
Civil Engineer of Brussels, Belgium :-
This invention relates to improvements in the construction of what are termed
"radiators," the object being more particularly to facilitate the putting together of
the various sections which when combined form the complete radiator, and to
enable any of the said sections to be removed and replaced without disturbing the
other sections, and also the improved construction of the outer tubes.
The improvements are clearly shown in the annexed drawings in which :-
Fig. 1, is an end elevation of a radiator partly in section.
Fig. 2, front elevation of radiator with part of casing removed.
Fig. 3, cross section of the internal and external tubes.
Fig. 4, plan with part of casing removed.
The radiator may be briefly described as a number of sections, composed of an
internal and external tube combined, with suitable means for securing the sections
together, the external tubes being for steam or hot water and the internal tubes for
the passage of air.
Each section consists preferably of one internal tube A, which may be made of
wrought iron, steel, copper or other metal, and an external tube of cast iron B, of
peculiar configuration.
These tubes are arranged concentrically as shown, leaving a space C, between
them, and having a tight joint at each end by expanding the ends of the malleable
internal tube A, until they fit tightly against the end openings of the external
tubes, but this method of forming the joint is not part of my invention, and other
means may be employed.
On the front and back vertical faces of the external tubes B, I form a number
of ribs or gills D, extending longitudinally from top to bottom or thereabouts, for
the purpose of increasing the radiating surface, and on the two opposite sides of
each end of the tube is a facing piece E, with a hole F through it, these faces with
the faces of the adjacent tubes will when drawn together form a tight joint, and
admit of the heating medium passing freely from one section to another.
In some cases I cut a recessed ring or annular groove G, round the hole or
passage F, in the faces E, in which I place a ring of lead or copper wire or other
material suitable for making joints, but which can be readily cut in two by the
edge of the grooves when sufficient force is applied to separate the sections.
In the front and back of the top and bottom ends of each external tube B, I
form a recess H, through the side walls I, of which, I pass bolts J, by which the
adjacent sections are drawn together at the faces, and secured.
The external tubes B, heated by water or steam give off their heat by radiation,
and the heated surface of the internal tubes A, which are open to the atmosphere
at both ends, induces a current of air to pass through them in an upward direction
thereby creating a constant and wholesome circulation of warmed air.
Having now particularly described and ascertained the nature of my said
communicated invention, and in what manner the same is to be performed, I
declare that what I claim, is :-
:-
1. In a radiator consisting of a series of concentric or internal and external

page_text: tubes with a continuous passage between them for the circulation of the heating
medium, making the upper and lower ends of the external tubes with side facings
round the connecting passages, so constructed that any section of the series of
concentric tubes may be removed without disturbing the others, substantially as
hereinbefore described and shown.
2. In a radiator consisting of concentric tubes A and B, making the front and
back faces of the external tubes B, with ribs or gills D, and constructing the side
facings E in such a manner that any section or set of tubes may be removed,
without disturbing the others substantially as described and shown.
3. In a radiator, the combination of an internal tube A, with an external tube B,
provided on two faces with ribs or gills D, side facing E, and bolt recesses H,
constructed and arranged substantially as hereinbefore described and as shown in
the drawings.
