PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Cooling or Heating Water and
other Liquids.
I, MICHAEL HOLROYD SMITH, of Albany Buildings, 47, Victoria Street, West-
minster, Consulting Engineer, do hereby declare the nature of this invention
to be as follows:
When it is desired to cool water or other liquids or to use hot water for dis-
tributing heat it is usual to pass it through a series of pipes provided with "gills
tliese pipes are usually of cast-iron.
When lightness is essential, as for example in motor car use, then drawn pipes
are employed and metal washers are threaded on separately and secured in
position by any convenient means.
When long pipes are required the threading and' securing of these washers is
difficult & costly..
The object of my invention is to overcome this difficulty and to increase the
radiating surface, and for this purpose, I take a long strip of thin sheet metal
preferably copper, though other suitable metal may be employed, and by passing
it through rolls or otherwise, I bend it into the form of the letter Vor UI then
at frequent intervals nick or cut across the ✓ or U part of the channel thus
formed, leaving the flanges continuous. The long strip of metal can then be
wound round the pipe inrough which the hot water circulates. The flanges
making good metalic contact therewith. The strip can be soldered to the pipe
or clamped, rivetted, or bolted at each end.
That the invention may be readily understood, it may conveniently described
as similar to the method employed in winding a paper frill round the shank of
a leg of mutton:
When the strip is wound round the pipe as described the Hanges regulate the
distance apart of the spirals and the Vs or Us form arches through which air
can circulate for cooling purposes.
Lshaped strips can be used in the same nianner but would not be equally
durable.
.
When a cluster or bank of tubes is required then a bridge-couple is employed
to which each tube end can be clamped preferably in a manner to facilitate
removal and re-attachment.
The bridge-couple is also provided with studs or like device so that it can be
held in a frame and still be free for the movement due to expansion and con-
truction.
It is obvious that this apparatus can also be used for collecting heat, for
example it could be inserted in the flue of a chimney, water passing through the
pipes would then be beated.

other Liquids.
I, MICHAEL HOLROYD SMITH, of "Albany Buildings, 47, Victoria Street, West-
minster Consulting 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:-
When it is desired to cool water or other liquids or to use hot water for dis-
tributing heat it is usual to pass it through a series of pipes provided with gills
these pipes are usually of cast iron.
When lightness is essential as for example in motor car use, then drawn pipes
are employed and metal washers are threaded on separately, and secured in
position by any convenient means.
When long pipes are required the threading and securing of these washers is
difficult and costly. The object of my invention is to overcome this difficulty and
to increase the radiating surface. in order that this invention may be more
easily understood, reference is made to the accompanying drawings—
Fig. 1, (Sheet 1) is a side elevation of a nest of pipes.
Fig. 2, (Sheet 2) is an end elevation of same.
For the purpose of this invention I take a long strip of thin sheet metal, prefer-
ably copper, though other suitable metal may be employed, and by passing it
through rolls, or otherwise, I bend it into the form of a letter Vor U. I then at
frequent intervals, nick or cut across the V or U part of the channel thus formed;
leaving the flanges continuous. The long strip of metal A can then be wound
round the pipe c.through which the hot water circulates. The flanges 1, making
good metalic contact therewith. The strips can be soldered to the pipe or
clamped, rivetted or bolted at each end!
That the invention may be readily understood, it may conveniently be described
as similar to the method employed in winding a paper frill round the shank of
a leg of mutton or ham. When the strip A is wound round the pipe as described,
the Hanges 1,, regulate the distance apart of the spirals and the V's or U's form
arches 2 through which air can circulate for cooling purposes.
shaped strips A can be used in the same manner, and are more easy of
manufacture and application, and can be arranged nearer together. In order that
the ends of the frill shall not form a cutting edge, I preferably double them down
at the tips as shown at 3 Fig. 1.
In Fig. 1, will be seen three modifications of the form of the frill At a V form;
A a loop form, A2 an L form, other modifications can be made, for example the
strips of the frill could be twisted.
When a cluster or bank of tubes is required, then a bridge coupling B is
employed to which, each tube end can be clamped, in a manner to facilitate removal
and re-attachment.
B is an example of a bridge coupling, preferably of a box shape, as shown,
and made of light metal such as an aluminium alloy. The coupling box is
provided with two faces 4. Shaped to receive the bell-mouthed end 5, of the
tubes C over which the clamping ring 6 has previously been placed and by
means of bolts, studs or set screws can be secured to the coupling box.
The coupling box is also provided with studs or projections 7, for supporting
them in a nest or frame such as D, leaving them sufficiently free for expansion
and contraction, which is also provided for by coupling the pipes alternately at
either end as indicated in Figs. 1, and 2.

page_text: If it is desired that these cooling tubes should not be exposed to view, they
can be covered in any convenient manner. E Fig. 2 shows a perforated metal
case for that purpose arranged so that air can not only enter at the perforations,
but also as indicated by the arrows.
For coupling up the supply of water or other liquids to be cooled, connection
can be made with the ends of the pipes in the usual way, or the faces shown on
the bridge couplings can be used, or any suitable modification thereof.
It is obvious that this apparatus could be used in the reverse order, viz. if
placed in a heated chamber, water would be warmed by flowing through it, or
by passing steam through the apparatus it could be employed for warming apart-
ments.
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:-
-
1. An apparatus for cooling water or other fluids substantially as illustrated
and described.
2. In an apparatus for cooling water covering the circulating pipes with a
suitable metalic "ham-frill," substantially as and for the purpose described and
illustrated.
3. Coupling pipes for water circulation or other purposes by bridge couplings
constructed substantially as illustrated and described.
Thatod this 7th day of Anvil 1900.
