PROVISIONAL SPECIFICATION.
An Improved Apparatus for Heating and for Cooling Liquids.
I, JAMES GEORGE DAVIES, of 19, Tuilerie Street, Hackney Road, Shoreditch,
in the County of London, Bar Fitter and Refrigerator Maker, do hereby declare
the nature of this invention to be as follows:-
-
The apparatus is specially applicable for heating and for cooling malt and
other liquors for public bars, hotels, restaurants &c. As a circulating refri-
gerator or heater by which any temperature can be obtained instantly within a
few degrees of freezing or boiling also supplying either extreme temperature.
The apparatus consists of a tank for generating heat or cold and fitted with
improved cylinders (described below) for equally distributing the liquids to be
heated or cooled.
For heating the cylinders are centred in a tank containing boiling water.
For cooling the cylinders are centred in an insulated tank charged with ice-
water, ice and other refrigerants.
The supply passing through cylinders to apparatus at bar forming junction
for supplying hot or cold water at extreme temperatures and also a jacket pan
for heating and for cooling malt and other liquors instantly at any required
temperature.
When the apparatus is not used for any length of time the highest or lowest
possible temperatures is maintained as a bye pass is provided that circulates
through generators for that purpose.
The improved cylinders consist of a single tube or a series of tubes with an
inlet and outlet chest at the ends thereof.
An Improved Apparatus for Heating and for Cooling Liquids
JAMES GEORGE DAVIES, 19, Tuilerie Street, Hackney Road, Shoreditch, London,
N.E., Bar Fitter, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
On the accompanying drawings Figure 1, represents a sectional elevation of
the improved apparatus as a heater for water, malt and other liquors.
Figure 2, represents a bar heating or cooling apparatus which also supplies
hot or cold water at extreme temperatures for bar purposes and for under
counter basins.

page_text: Figure 3, represents a pillar bar valve also basin valve provided with bye pass
for supplying hot or cold water only at either extreme temperatures.

Figure'l consists of tank A filled with water to overflow M. Heat is generated
by gas N. O heating shafts that pass through tank A that form draught for
gas and condensed steam under loose cover P. P¹ vapour outlet. O' gas supply
inlet. Heating cylinder B is centered in generating tank A. It is a single tube
with inlet C and outlet C' with chambers at each end thereof. The inner
-divisions. C are. provided with a number of holes collectively the same size as
inlet D which causes equal distribution to all parts of cylinder. For cooling
the cylinder is made with any number of tubes that may be required with inlet
and outlet chamber as before described--not shewn.D main supply inlet,
D' ball valve for supplying generating tank A. E outlet supplying the apparatus
shown in Figure 2 and Figure 3 with hot water..

J heating chamber for heating liquids to any temperature. L jacket overflow
circulating to generator and acting as a bye, pass which is controled by valve F1
for retaining extreme temperature when apparatus shewn in Figure 2. is not
in use. LL, water line when at bye pass. K draw off cock for malt and other
liquors to be cooled or heated. G draw off bar cock for water only.
Figure 3. H and H¹ basin valves, L₁ bye pass outlet. R pillar bar valve
for hot or cold water only, at extreme temperatures.

For cooling, tank A shewn in Figure 1 is insulated and charged with ice and
other refrigerants. B cooling cylinder supplying apparatuses. shown in
Figures 2 and 3.
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. A spécially constructed bar fitting by which liquids can be cooled or heated
instantly.
2. In combination an improved method for equally distributing liquids to be
cooled or heated by chambers as herein before described to any required tempera-
ture at any elevation.
