IMPROVEMENTS IN AND CONNECTED WITH RADIATORS EMPLOYED FOR HEATING PURPOSES
Year: 1885

page_text: I LEWIS WALKER LEEDS of 38 Old Jewry in the City of London Heating and
Ventilating Engineer do hereby declare the nature of my said invention for
IMPROVEMENTS IN AND CONNECTED WITH RADIATORS EMPLOYED FOR HEATING
PURPOSES, to be as follows :-
In specification No 511 of 1883 I have described certain improvements in the
manufacture of radiators, part of such improvements consisting in casting or
forming the radiators in separate pieces or sections which are subsequently bolted
together by means of tie rods.
My present invention consists of certain improvements in the construction of
radiators made in sections and relates mainly to the means by which such sections
are secured together. The tubes which connect the upper and lower chambers,
I prefer to form with one or more internal divisions so as to form two or more
pipes with common inlet and outlet necks.
The tubes may be conveniently provided with a screw thread at their lower end
adapted to be received by the lower chamber while the upper chamber or cap may
be secured to the top of said tubes by means of a comparatively short bolt, one
end of which is adapted to pass in and be held within the upper neck of the tube
by means of a head or nut, while the other end of said bolt, screws into or passes
through the top chamber or cap and holds it securely down upon the tubes. This
method of bolting the sections together may obviously be employed for connecting
the bottom chamber to the lower necks of the tubes if desired, while the tubes
themselves may be of a single section throughout if preferred.

I, LEWIS WALKER LEEDS of 38 Old Jewry in the City of London, Heating and
Ventilating 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 :-
In specification No. 511 of. 1883 I have described certain improvements in the
manufacture of radiators, part of such improvements consisting in casting or
forming the radiators in separate pieces or sections, which are subsequently. bolted
together by means of tie rods, longitudinal or vertical bolts which are used to hold
the sections and the top and bottom chambers together. My present invention
consists of certain improvements in the construction of radiators made in sections 1
and relates mainly to the means by which such sections are secured together. In
order that my invention may be clearly understood reference is made to the
accompanying drawings in which-
Fig. 1 represents in sectional elevation a portion of a radiator.
Fig. 2 represents in section the tube when screwed to the base.
Fig. 3 represents in section the tube and base when held by a separate.bolt.
Fig. 4 represents a plan view of the top of a tube with loose connecting bolt
and nut.
Fig. 5 represents the top chamber as being bolted to the tube by a loose bolt
without a nut and—
Fig. 6 represents a plan view on line a, a, thereof.
-
The tubes A which connect the upper and lower chambers B, C, I prefer to form
with one or more internal divisions D, so as to form two or more pipes with common
inlet and outlet necks E.
The tubes A may be conveniently provided with a screw thread at their lower
end adapted to be received by the lower chamber C, as shown in Fig. 2, while the
upper chamber or cap B, may be secured to the top of said tubes A by means of a
comparatively short bolt G, one end of which is adapted to pass in and be held
within the upper neck E, of the tube by means of a head or nut H, while the other
end of said bolt screws into or passes through the top chamber or cap and holds it
securely down upon the tubes as shown. This method of bolting the sections
together may obviously be employed for connecting the bottom chamber C, to the
lower necks E, of the tubes A, as shown in Fig. 3, while the tubes themselves may
be of a single section throughout if preferred, but when divided as shown in Figs.
and 3, I find that the end of the divisions forms a convenient rest for bolt G, when
being screwed through head or nut H.
•
Where the tubes are not screwed directly into the top or bottom chambers a
convenient and serviceable joint between the parts may be obtained by means of
asbestos or other suitable packing rings I, as clearly indicated in the drawings.

page_text: The ordinary inlet and outlet ports for conducting the heating medium to and
from the radiator are supplied in the usual manner.
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
In radiators the improved means of securing the tubes to the upper or lower
chambers, substantially as herein before described.
