COMPLETE SPECIFICATION.
Improved Hot Water or Steam Heating Apparatus or Radiators.
I, GEORGE LLOYD BERRY, of No. 16 Regency Street, Westminster, in the
County of Middlesex, 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:-
My invention relates to the construction of hot water or steam heating apparatus
or radiators, in which tubular sections having gills or ribs projecting from their
outer surfaces, are so arranged on a box that communicates with the outer air that
such air entering the box ascends thence through vertical spaces formed between
the several tubular structures so as to become heated before entering the room.
According to my present invention I am enabled to dispense with one half the
joints between the tubular section of such ventilating radiators as at present
constructed while at the same time preventing such joints from becoming leaky, by
so arranging them that the metal of the tubular sections can expand and contract
freely without straining the joints.
I will describe my improved construction for this purpose with reference to the
accompanying drawing, in which Fig. 1 shews a sectional plan of part of such a
radiator, and Fig. 2 shews a part side elevation of one of the tubular sections.
The radiator is composed of any desired number of tubular sections A A²,
heated internally and placed side by side; they have such a transverse sectional
configuration, as to form between them enclosed spaces B into which project the
gills or ribs C; these spaces communicate at bottom with a box (not shewn) on
which the apparatus stands, and which communicates with the outer air, so that
such air rises through the spaces B, taking up heat from the surfaces of the
sections A and the gills C thereof, and issuing into the room through the open tops
of such spaces.
The separate sections communicate with each other through a single central
bossed opening D into which is screwed a short itube or nipple having right and
left handed screw threads, so that by screwing these up, the faced meeting surfaces
of the bosses are brought close together, so as to form a steam and water tight
joint, in a manner well understood. A similar joint is also formed at the tops of
the sections.
By thus securing the sections together by a single central joint at top and at
bottom, it will be seen that the two ends of each section are free to expand and
contract independently of each other, without putting any strain on the joints,
which consequently cannot become leaky.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed I declare that what I
claim is :-
Constructing hot water or steam heating apparatus, or radiators, with tubular
sections such as A' A² so formed as, when fitted together, to form air spaces B.
between them, into which project gills or ribs C formed on the sections, such
sections being made to communicate with each other through a single tubular
joint D at the upper and lower ends, substantially as described.
