PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Heating or Cooling Water and other
Liquids.
THOMAS EUSTACE BARRALET, of 51a, Queen Victoria Street, London, Secretary,
do hereby declare the nature of this invention to be as follows:-
This invention relates to means for distributing, spreading or dividing water
or other liquids for the purpose of heating or cooling them, as may be desired.
The liquid is directed by a pipe or pipes on to a plate or surface, flat, curved or
sloped. Holes of convenient size and shape are provided at suitable intervals,
preferably so arranged that the liquid can pass in a straight line from the source
of supply to any of the holes without having to pass over any other hole. Con-
tiguous to that side or end of each hole which is furthest from the source of supply
is a projecting tongue or fin.
The liquid runs over the plate or surface in a thin film or sheet. In this form
it passes over the holes without entering them, but striking the tongues or fins
a back pressure is caused which forces it through the holes. The liquid being
thus divided can be directed over any surface or other arrangements for heating
or cooling it. The quantity of water which passes through each hole is in direct
proportion to the rate at which it passes over the surface, as a greater speed or
force produces a greater pressure against the tongues or fins and consequently
forces more water (or other liquid) through the holes. While chiefly intended
for use in water heaters of the Geyser type this invention is applicable to all
apparatus for heating or cooling water and other liquids in which it is desirable
to divide or distribute the liquid and which are not required to work under
pressure.
COMPLETE SPECIFICATION.
Improvements in Apparatus for Heating or Cooling Water and other
Liquids.
THOMAS EUSTACE BARRALET, of 51A, Queen Victoria Street, London, Secretary,
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 relates to means for spreading, dividing or distributing water
or other liquids for the purpose of heating or cooling them as may be desired.

page_text: The accompanying drawings shew the system, Fig. 1, plan; Fig. 2, partly plan
and partly elevation: Fig. 3, sectional elevation. The liquid is directed by a
pipe or pipes (e) on to a plate or surface (a) flat, curved, sloped, convex or of
other suitable shape. Holes of convenient size and shape (6) are provided at
suitable intervals, preferably so arranged that the liquid can pass in a straight
line from the source of supply to any of the holes without having to pass over
any other hole.
Contiguous or near to that side or end of each hole which is
farthest from the source of supply is a projecting tongue or fin (c). The liquid
In this form it passes
runs over the plate or surface (a) in a thin film or sheet.
over the holes (b) without entering them, but striking the tongues or fins (c) a
back pressure is caused which forces it through the holes. The liquid being
thus divided or distributed can be directed over any surface (d) or other arrange-
ments for heating or cooling it. The quantity of water which passes through each
hole is in direct proportion to the rate at which it passes over the surface (a), as
a greater speed or force produces a greater pressure against the tongues or fins (c)
and consequently forces more liquid through the holes. While chiefly intended
for use in water heaters of the Geyser type this invention is applicable to all
apparatus for heating or cooling water or other liquids in which it is desirable to
divide or distribute the liquid and which are not required to work under pressure.
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 an apparatus for heating or cooling water or other liquids the use of a flat,
sloped, curved or convex surface over which the liquid flows and which is provided
with holes or apertures and projecting tongues or fins for the purpose of directing
the liquid through such holes or apertures, substantially as shewn and described.
