PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Cooling Liquids.
HENRY CLARKE 82 Stanley Street Burslem Staffordshire Mechanic do hereby
declare the nature of this invention to be as follows:-
66
This invention has reference to improvements in, and which are applicable to
that class of apparatus or machinery, known in the trade as refrigerators," and
used for cooling all kinds of liquids, and the object of my said invention is to
construct such refrigerators that when in use they will be more efficient than the
refrigerators at present in use.
In order to carry my said invention into practice, in the front end of such
machine and beneath the inlet end of the pipe or pipes, conveying the hot liquids
to the machine, I attach or place on side rests or by any suitable means, any
number of earthenware, electroplated metal, or iron plates or shelves, at suitable
distances apart, the front edge of each plate or shelf being curved or bevelled, and
perforated with round or any shaped holes, each plate or shelf being slanted towards
the front end of the machine.
An air screen or conductor in the same frame or in a separate framing is placed
or fitted with hinges or by any suitable means immediately in front of the said plates
or shelves, the inner ends of each pair of pivotted doors or shutters of the said air or
draught conductor being pressed together by means of a weight or spring fixed
on or between each pair of doors or shutters, which said doors or shutters can be
forced apart any suitable distance, by means of fingers formed on or attached to a
metallic plate or rod, which is secured to the framing in any suitable manner, with
a hand wheel and screw at the top, so as to raise or lower the said fingers, and thas
open or close the door or shutter.
It will be understood that when the liquids to be cooled, flow or fall from the
pipe or pipes on to the top slanting shelf or plate, it will be caused to fall from one
shelf on to the succeeding or following shelves, by means of the slanting or incline
position of each shelf, and during its descent from one shelf to another, a current
of air is drawn through by means of a revolving fan fixed at the back end of the
machine, and regulated by the air shutters or doors.
Dated this 26th day of June 1894.

I HENRY CLARKE 82 Stanley Street Burslem Staffordshire Mechanic 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 has reference to improvements in and which are applicable to that
class of apparatus, known in the trade as refrigerators, and used for cooling liquids.
And the object of my said invention is to construct such refrigerators, that when
in use, they will be more efficient than the refrigerators at present used.

Fig. 1 represents a side elevation of an apparatus made with both ends alike,
and especially applicable for use in breweries, factories, and other like works, for
cooling wort, engine condense water, and the like.
Fig. 2 represents a longitudinal sectional elevation of Fig. 1.
Fig. 3 represents a longitudinal sectional elevation of a single ended apparatus,
applicable for use in dairies for cooling milk and the like.
Fig. 4 represents a front end elevation of Figs. 1, and 3.
Fig. 5 represents a front elevation of a shelf or plate.
On the drawings, A represents the iron framing of such apparatus, B the fan
box or compartment, C the fan shaft, D the pulley on fan shaft.
As the liquid to be cooled is conveyed to the apparatus by means of the feed or
supply pipe or tube E, it is regulated by means of the taps or valves F, through
which it flows into the top receiving trough G, and from holes in the bottom of
which it drips on to a series of any required number of incline iron or any suitable
metal shelves or plates H. fixed at suitable distances apart, in a framing of iron or
any suitable metal, each shelf or plate being curved or bevelled at the front end or
edge, and perforated with round or any shaped holes as shown in Fig. 5, and turned
up at the sides and inner ends to prevent the liquid from overflowing.
And resting
on side rests or brackets (not shown) such brackets being fixed or fastened by
bolts or by any suitable means to each side of the framing A, and each shelf or
plate slanting in the same direction, at any suitable angle towards the front end or
ends of such apparatus. A round hole is pierced or drilled in each bracket or rest
near the front end, and each shelf or plate has a round stud fixed or fastened
underneath at each side near the front end so that when the plates or shelves are
in working position the studs in the aforesaid shelves or plates fit in the holes in
the said brackets so as to keep them in position.
And during the.descent of the liquid from one shelf or plate on to the succeeding
or following shelves or plates it is met by an inrushing current of cold air drawn
through an air screen or conductor, by means of a revolving fan I, fixed or fitted
ou the shaft C, supported in suitable bearings at each side of the fan box B, and
.rotary motion being transmitted from a main driving pulley by means of a suitable
⚫ endless belt or strap, passing around such main pulley and pulley D, fitted on fan
shaft C.
Such air screen or conductor consisting of a number of fixed, or fixed and pivotted
incline iron or any suitable metal shutters or doors J, K, fitted or fixed in the
framing A or in a separate framing and attached or fastened to the framing A by
hinges or by any suitable means immediately in front of and contiguous to the said
slanting shelves or plates H.
The hand wheel L at the front end of the said air screen when screwed upwards
lifts the several pivotted shutters or doors K, by means of the fingers M formed
on or attached to a metallic plate or rod N, which is secured by any suitable
means to the front end of the framing O of the said air screen. When the said
hand wheel L is unscrewed the inner ends of the said pivotted shutters or doors K,
fall towards the inner ends of the fixed incline shutters or doors J thus decreasing
the quantity or current of inflowing air.
Each apparatus having a main regulating slide valve or door R which can be
externally regulated by the fiuger.and quadrant S.
When the liquid is cooled it falls or flows from the bottom shelf or plate H, into
a bottom receiving trough P, and by means of a connecting trough Qis conveyed
to the centre of the apparatus, and from thence to the vats or any suitable storage.
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 combination;-in refrigerating apparatus of the nature aforesaid ;-
Series of slanting shelves or plates H, each made with curved or bevelled front

page_text: end and perforated with round or any shaped holes, with the sides and inner end
turned up.
The air screen or conductor at the front end or ends of the apparatus fitted with
any required number of fixed, or fixed and pivotted incline shutters or doors J K
the inner ends of the pivotted shutter or doors are moved apart from the inner ends
of the fixed shutters or doors by means of a hand wheel L or its equivalent, and
the fingers M, on metallic plate or rod N, and the whole arrangement operating
substantially as hereinbefore described and set forth.
Dated this 20th day of March 1895.
