Improvements in Radiators for Heating Buildings and the like.
I, WILLIAM THOMAS SUGG, of Vincent Works, Regency Street, Westminster,
London, S.W., Engineer, do hereby declare the nature of this invention to be
as follows:
This invention relates to that class of heating apparatus known as radiators,
the object of the present invention being to ensure proper circulation of the
heating medium, and to provide for the contraction and expansion of the parts,
at the same time obtaining perfect joints.
To this end the invention consists in adapting inside, and concentric with the
ordinary pipes, supplemental tubes, which are fixed at the upper ends to a con-
venient part of the apparatus, the lower ends being free, and extending nearly
into the chamber at the bottom.
At the top end these tubes are provided with a series of holes through which
the heating medium can pass out into the ordinary tubes.
Suppose the heating medium to be steam. the steam will be introduced into
the chamber at the bottom, and will pass up both the ordinary pipe and the sup-
plemental tube, but the latter. being, so to speak, jacketted, will keep hot longer
than the outer pipes.
Thus the steam outside will be condensed more or less,
and produce a vacuum, which will be immediately filled with steam from the
supplemental tube. As the steam will always fly to the hottest part, the inner
tubes will, after a time, concentrate to themselves the hot steam, and thus circu-
lation will be ensured.
The tubes may be secured to the top of the pipes in any steam tight manner.
and the pipes may be loose, being merely held in position by guides; thus, the
pipes will be free to expand and contract without loosening the joints, and the
tubes, having one end free, will also expand and contract.
When a chamber is employed at the top as well as the bottom, the tubes are
secured to the top of the chamber and the pipes to the bottom of the same, the
effect being as before described.
By these means, all expansion joints will be done away with, and the construc-
tion of the apparatus is much simplified.
The ordinary pipes may, if desired, be made with ribs, to increase the heating
surface.

I, WILLIAM THOMAS SUGG, of Vincent Works, Regency Street, Westminster.
London. S... Engineer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This invention relates to that class of heating apparatus known as "Radiators."
the object of the present invention being to ensure proper circulation of the
heating medium, and to provide for the contraction and expansion of the parts
at the same time obtaining perfect joints.
To this end, the invention consists in adapting inside, and concentric with,
the ordinary pipes, supplemental tubes, which are sixed at one end to a con-
venient part of the apparatus, the other end being free, and extending nearly into
a chamber at top or bottom of the ordinary tubes.
In the accompanying drawings.
Fig. 1 is a side elevation, partly in section, of the improved radiator;
Fig. 2 is an end elevation, partly in section; and
Fig. 3 is a cross section of a heating pipe.
A is the base, consisting of a suitable casting, having two horizontal super-
posed chambers, B and C, therein, the chamber B serving as a steam chamber.
having an inlet at B', and the chamber C serving as a condensed steam chamber,
with an outlet at C.
1) are the heating tubes, formed with fins D¹ in the usual way, and with a
chamber at top. These tubes D) are screwed into tapped holes in the top of
the chamber C. The chamber De is provided, at top, with internally-threaded
tubular extensions E. which are stopped, and to which an ornamental top F is
secured by the screws E. or in any other convenient manner, which will allow for
contraction and expansion of the parts.
Gare steam tubes, which are screwed into or otherwise secured to the parti-
tion II, which forms the top of chamber B or the bottom of chamber C. These
tubes Gare inserted in the heating tubes D. and the other ends are free, and
extend into the chambers D³.
The action is as follows): --Steam is let into the chamber B by the inlet B',
and passes up the tubes G into the chamber D. The steam then passes down-
wards through the heating tubes D outside the tubes G (which are thus steam
jacketted and kept hot), rendering up its caloric to the tubes D and fins D¹.
The steam becomes thus more or less condensed, and produces a vacuum in the
tubes D. which is immediately filled with fresh sicam, and thus circulation is
ensured.
The water of condensation (if any) and the cooled steam pass into the cham-
ber C, from which they are drawn off by the outlet C in any convenient manner.
By constructing radiators as above described, it will be seen that the necessity
for expansion steam joints is entirely obviated. for the base A. and the heating
tubes D all expand together, and the steam tubes G are free to expand and con-
tract independently, and all without interfering in the least with the circulation
which is perfect.
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 radiator for heating buildings and the like, constructed, arranged, and
operating as herein shown and described.

page_text: 2. In a radiator for heating buildings and the like, ensuring perfect circula-
tion, and obviating the necessity for expansion steam joints, by inserting, in the
heating tubes, supplemental tubes having one end free, as shown and described.
