page_text: COMPLETE SPECIFICATION.
I ALFRED WATERS of the Paragon Works Vicarage Road Croydon in the
County of Surrey Sanitary Engineer do hereby declare the nature of my invention
for "IMPROVEMENTS IN HOT WATER PIPES FOR HEATING BUILDINGS " 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 improvements in the construction and combination of
hot water pipes used for heating churches mansions, greenhouses and other
buildings and has for its object principally to reduce the volume of water requiring
to be heated for producing a given power and at the same time to obtain a larger
amount of heating or radiating surface than with a corresponding pipe of the
ordinary circular section.
On the accompanying drawing Figuro 1 represents a vertical sectional elevation
of a series of hot water pipes mado according to my invention and combined with
coil boxes and Figure 2 a section of one of the pipes on line 1. 2. in figure 1 like
letters of reference indicating corresponding parts in both figures.
In carrying out my invention I form a hot water pipe a of a cruciform section in
lieu of circular as at present that is to say I make the bore b of the pipe a cross-shaped
as seen in figure 2 the section of the metal around the bore b being of a similar
shape and ornamented (or not) with beadings c, mouldings or other devices as
desired-On each end of a pipe a I cast or form a circular flange d having a short
circular spigot e on its face the flange d and spigot e being respectively faced and
turned so as to accurately fit the corresponding faucets fand the faced surfaces g
of the coil boxes h when so combined-Or in the case of circulating lengths of
pipes the ends of each pipe a may be alternately formed with a spigot and faucet
for fitting into the succeeding pipe-Between the joints & and g (or between the
flanges & in the case of circulating pipes) I may interpose packing rings of India
rubbor or other suitable material.
By my invention I obtain the following advantages (1) As compared with an
ordinary circular pipe of the same diameter or extremo dimension the volume of
water requiring to be heated is reduced to a very large extent and at the same timo
the heating or radiating surface is increased whereby the sizes of circulating mains
for the supply may be reduced and economy in the consumption of fuel obtained.
(2.) The pipes being all cast to dead lengths turned and faced on their flanges
they can be combined and bolted together without the use of skilled labour as is

page_text: at present necessary with ordinary socket or flange pipes thereby greatly reducing
the cost of fixing a heating apparatus in which such pipes are used.
(3.) As these pipes are capable of being highly ornamented coil cases may be
dispensed with.
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:
The construction and use of hot water pipes having a cruciform section in
combination with circular flanges and spigots and with faucets respectively faced
and turned substantially as and for the purposes herein before described and
illustrated by the accompanying drawing.
