AN IMPROVEMENT IN CONDENSER COILS
Year: 1884

page_text: PROVISIONAL SPECIFICATION.
I, THOMAS GERRARD Dow, of the town and county of Lanark, Engineer &
Oil Manufacturer, do hereby declare the nature of my said Invention for "AN
IMPROVEMENT IN CONDENSER COILS;" to be as follows:-
-
The object of this Invention is so to form the coils of piping employed for
condensing oils, steam, or other vapours that they may be self-supporting when
erected in tiers of horizontal pipes, and the use of separate supports may be avoided.
For this purpose I cast the individual pipes, which make up the coil, with
flanges of rectangular form or of similar shape, at or near the faucet joints, and also
if need be at or near their mid-length, the position of the Banges being the same
on all the pipes, so that when the pipes are fitted horizontally over each other, the
lower edges of the flanges on one pipe rest on the upper edges of the flanges on the
pipe below. The flanges thus form a solid vertical support at any required number
of points round the coils.
The pipes of condenser coils are very commonly arranged in the form of an open
oblong or rectangular figure, and when so arranged the supporting flanges may be
conveniently placed near each corner on either the longitudinal or transverse pipes,
or the end pipes may be bent round to meet the longitudinal pipes, and have the
flanges formed on them near the joint.

I, THOMAS GERRARD Dow, of the town and County of Lanark, Engineer and
oil Manufacturer, do hereby declare the nature of my said Invention for AN
IMPROVEMENT IN CONDENSER COILS;" and in what manner the same is to be
performed, to be particularly described and ascertained, in and by the following
statement
The object of this Invention is so to form the coils of piping employed for con-
densing oils, steam, or other vapours that they may be self-supporting when erectod
in tiers of horizontal pipes, and the use of separate supports may be avoided.
For this purpose I cast the individual pipes which make up the coil, with flanges
of rectangular form or of similar shape, at or near the faucet joints, and also if need
bo at or near their mid-length, the position of the flanges being the same on all the
pipes, so that when the pipes are fitted horizontally over each other, the lower
edges of the flanges on one pipe rest on the upper edges of the flanges on the pipe
below. The flanges thus form a solid vortical support at any required number of
points round the coils.
The pipes of condenser coils are very commonly arranged in the form of an open
oblong or rectangular figure, and when so arranged the supporting flanges may be
conveniently placed near each corner on either the longitudinal or transverse pipes,
or the end pipes may be bent round to meet the longitudinal pipes, and have the
flanges formed on them 'near the joint.
In the accompanying Drawings, Figures 1, 2, and 3 are respectively a side
elevation, a cross section, and plan of an arrangement of condenser coil embodying
my improvements.
The pipes A of the coil are each cast with rectangular flanges a at the faucet
joints, and the end pipes have also rectangular flanges a cast on them at near their
mid length. The position of these flanges are such that the lower edges of the
flanges on one pipo, or horizontal row of pipes rest on the upper edges of the
flanges on.the horizontal row beneath, and thus serve as a solid vertical support at
various points round the coil.
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
Forming the pipes of condenser coils with rectangular or similar flanges, to serve
as a means of support for the coils, substantially as herein set forth.
