PROVISIONAL SPECIFICATION.
An Improvement on the Round Pipes in and in connexion with
the Warming of Churches, Chapels, Conservatories, or other
Buildings where required to be Heated on the Low Pressure or
Circulating System.
HENRY BROOK, 19 Spring Grove Street HENRY WATSON Birkby Old Road
Birkby JOSEPH HARDCASTLE 10 Bay Hall Terrace Birkby all Whitesmiths of
Huddersfield of the County of York, do hereby declare the nature of this invention
to be as follows:-
The improvements consist in having a number of indented flutes, cast in the
pipes, whereby the outside surface area or heating surface, is greatly increased,
and at the same time, the space for water is greatly decreased. The pipes at each
end will, for the convenience of fixing, be on the old principle, that is for fixing,
length after length together, having a round socket or female end, at one end, and
spigot, or male end at the other, the indented flutes running lengthwise with the
pipe.
In case of coils, the pipes will be round spigot or male at each end, as at present
in use.
The flutes in the pipe, may be of irregular shape or true section of a circle as
desired, for the convenience of casting, the inner surface of the pipe, to follow the
same form as the outer, as near as possible so that there may be, a uniform thickness
throughout the fluted portion of the pipe.
For the sake of ornamentation or otherwise, the flutes need not run from end to
end, but be stopped near the middle, the middle for a short length being round as
at the ends.
There are other types or sections of pipes used for coils, besides the round, and
in many cases the flutes if added would improve them.

COMPLETE SPECIFICATION.
An Improvement on the Round Pipes in and in connection with
the Warming of Churches, Chapels, Conservatories, or other
Buildings where required to be Heated on the Low Pressure or
Circulating System.
We, HENRY BROOK, HENRY WATSON, and JOSEPH HARDCASTLE, of 10, Bay
Hall Terrace, Birkby, Huddersfield, in the County of York, Whitesmiths, 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:-
This invention refers to heating apparatuses or systems for warming or
distributing heat in dwelling houses, warehouses, manufactories, greenhouses,

page_text: conservatories, churches and other buildings or structures, and our improvements
consist in constructing the circulating or heat radiating pipes with longitudinal
indentations or deep flutes which give a largely increased area of heating surface
and a proportionately diminished internal or sectional area for the circulation of
water, steam or air, whereby while reducing the volume of water or steam hereto-
tore required in heating the pipes, a greater amount of heat is distributed or
radiated therefrom into the room or building.
The indentations or flutes extend longitudinally nearly the full length of the
pipes whose extremities are made or cast round in cross section in order that they
may be fitted or coupled to each other or to the coil boxes or water or steam
supply or circulating chambers in the manner common to the round or tubular
pipes now in use. In casting or forming the indented or fluted pipe we make the
interior surface to correspond in formation to the outer surface so that a practically
uniform thickness of metal is ensured throughout the pipe or fluted portion.
For the purpose of fully explaining our invention, reference is herein had to the
accompanying drawings forming a part of this Specification, wherein :-
Figs. 1, 2, 3, 4, 6 and 7 are longitudinal elevations of pipes constructed according
to our invention, and Figs. 5 and 8 are transverse sections of Figs. 4 and 7
respectively.
Referring to the drawings, A represents a heating or radiating pipe which is
cast with a number of longitudinal indentations or flutes B either of irregular
shape, or true, sections of a circle as in Fig. 5, the said indentations or flutes
greatly increasing the exterior area of heating or radiating surface of the pipe as
compared with the heating surface of an ordinary round or tubular pipe of the
same diameter, and likewise diminishing considerably the water steam or air
passage through the pipe, which therefore requires less water or steam to fill it
and admits of the boiler capacity for a given length of piping being reduced and a
saving in the consumption of fuel effected.
The inner surface of the pipe is made to correspond with the outer formation in
order that the fluted portion may be of uniform thickness throughout.
The extremities C, D, of the pipes A from the termination of the indentations B,
are made or cast round or tubular, in cross section, for convenience of fixing or
coupling, and to enable said pipes to be used in existing apparatuses or systems in
lieu of the ordinary tubular pipes. When the said pipes are to be coupled together
in lengths or end to end, we provide one end thereof with a socket E to receive
the male end D of the next pipe as shewn in Figs. and 4; but those pipes which
are to be fixed or coupled to coil boxes, or water or steam chests or chambers are
made without a socket as shewn in Figs. 2, 3, 6 and 7, in both cases the ends
of the pipes corresponding to those now in use so that the pipes may be
interchangeable.
Instead of the indentations or flutes B being cast from end to end of the pipe,
they may be cast in two or more sections (as illustrated in Fig. 3) with short spaces
or lengths F of round pipe between them which can be used for ornamentation or
other purposes, and also to afford a break or change to the flow of water through
the pipe.
In Figs. 7 and 8 we shew the indentations or flutes B made or cast in an oval
form or section of pipe, the extremities thereof either being oval as shewn in full
line at G or round as indicated in dotted line at H, in Fig. 8. Other types or
sections of pipes used for heating or warming purposes may be similarly cast or
formed with indentations or flutes B for increasing their radiating surface and
diminishing the internal sectional area or thoroughfare.
For the conveyance only, of water or steam to the heating apparatus or
radiators, the ordinary plain round or oval pipes may be used.
In addition to the advantages previously mentioned as being obtained by our
improved construction of pipe, there is a more rapid circulation of warm or hot
water through the pipes, and the space cccupied by the heating apparatus or
radiator may be reduced.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
Firstly. Pipes for radiating or distributing heat constructed or cast with longi-
tudinal indentations or flutes such as B and having the interior walls or surface of
corresponding formation to the outer surface to give a practically uniform thickness
of metal throughout substantially as herein shewn and described and for purposes
set forth.
Secondly. For radiating or distributing heat, the employment of longitudinally
fluted or indented pipes of corresponding exterior and interior formation or
configuration having their extremities cast or made round in cross section, or plain
section of the pipe, and adapted for coupling together end to end or to coils,
substantially as herein shewn and described.
