PROVISIONAL SPECIFICATION.
Improvements in or relating to Chocolate Coolers or the like.
I, DANIEL MOREY HOLMES, of 17, Craven Park, Willesden, in the County of
Middlesex, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to chocolate coolers and the like apparatus intended for
the cooling of heated liquid or semi-liquid material.
According to this invention a tank preferably water jacketted, has the greater
part of its interior occupied by a cooling roller and a beater, arranged to revolve
on parallel axes in its contents.
The cooling roller is conveniently hollow and rotatable on a shaft into which
latter circulating water can be led to cool the interior of the roller; for instance
the shaft may at the middle of the axial length of the roller be plugged, there
being perforations in the shaft at opposite sides of the plug, the cooling water
being delivered by way of one end of the shaft and one series of perforations and
withdrawn by way of the other series of perforations and the opposite end of the
shaft, so that the circulation of the fluid contents of the roller is ensured.
Fans or blades may be provided in the interior of the cooling roller to improve
the circulation of the cooling-liquid therein.
The beater may be of any desired type but preferably is one which is provided
with helical blades and it may be geared to the cooling roller by gearing so that
they rotate in company. Stuffing boxes are provided at the places at which the
shaft extends through the ends of the cooling roller and also where the journals
of the roller and beater extend through the wall of the tank.
There may be a scraper arranged to bear upon the surface of the cooling roller
to remove any film of material which may gather upon it and tend to impair the
efficiency of its cooling surface.
Means may be provided for delivering a heating fluid in place of a cooling fluid
into the interior of the tank jacket and of the roller so as to loosen any coating
of chocolate which might collect upon the surface of the tank or of the roller.

Improvements in or relating to Chocolate Coolers or the like.

County of Middlesex, but now of Metropolitan Machine Works, 34, 36 and 38,

page_text: Watts Street, New York, United States of America, 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: --
This invention relates to chocolate coolers and the like apparatus intended for
the cooling of warm chocolate or other semi-liquid material.
According to this invention a tank preferably water-jacketted, has in its interior
a cooling roller and a beater arranged to revolve preferably on parallel axes or
otherwise to operate side by side in its contents.
The cooling roller is conveniently hollow and rotatable round or upon a shaft
into which latter circulating water can be led to cool the interior of the roller;
for instance the shaft may at the middle of the axial length of the roller be
plugged, there being perforations in the shaft at opposite sides of the plug, the
cooling water being delivered by way of one end of the shaft and one series of
perforations and withdrawn by way of the other series of perforations and the
opposite end of the shaft, so that the circulation of the fluid contents of the roller
is ensured.
Fans or blades may be provided in the interior of the cooling roller to improve
the circulation of the cooling liquid therein, for instance by having motion in rela-
tion to the roller.
The beater may be of any desired type but preferably is one which is provided
with helical blades and it may be geared to the cooling roller by gearing so that
they rotate in company. Stuffing boxes may be provided at the places at which
the shaft extends through the ends of the cooling roller and also where the
journals of the roller and beater extend through the wall of the tank.
There is a scraper arranged to bear upon the surface. of the cooling roller to
remove any film of material which may gather upon it and to allow the roller to act
on fresh material.
If desired the beater may be dispensed with and the cooling roller and its scraper
used alone.
Means may be provided for delivering a heating liquid in places of a cooling
fluid into the interior of the tank jacket and of the roller, so as to loosen any coat-
ing of chocolate which might collect upon the surface of the tank or of the roller.
In the accompanying drawings,
Fig. 1 is a plan of one construction of cooler according to this invention.
Fig. 2 is a longitudinal section on the line 22 of Fig. 1 and Fig. 3 is a trans-
verse vertical section on the line 3 3 of Fig. 1.
Like letters indicate like parts throughout the drawings.
A is a tank provided with a jacket A¹ so that the contents of the tank may be
cooled by water or other cooling medium circulated in the jacket A¹ through
pipes A B is a hollow cooling-roller carried on hollow trunnions B₁ which are
free to turn in the walls of the tank A. The roller B is kept cool by means of
water or other cooling medium which enters its interior through holes B3 at one
end of a hollow shaft B2 which passes through the hollow trunnions B¹ of the
roller B and leaves through similar holes at the other end. The hollow shaft Ba
is plugged as at B4 in order that the water may not pass through it without enter-
ing the roller B. *
Vanes or blades B³ are carried by the hollow shaft B3 which is driven either
independently as by the pulley B6, or by gearing so that it rotates in the opposite
direction to or faster than the roller B. The water in the interior of the roller B
is thus caused to swirl or eddy and to cool the roller efficiently.
A beater comprising a shaft C having blades C¹ mounted helically upon it is
placed in the tank A. side by side with the cooling roller B. The shaft C is driven
by means of a pulley C and carries a gear wheel D which drives another gear
wheel. D mounted upon one of the hollow trunnions B¹ carrying the roller B.
The beater C stirs up and beats the material in the tank keeping it uniform
and aiding the cooling operation. A scraper E is provided fixed in any con-
venient manner so that it serves to prevent a coat of chocolate forming upon the

page_text: cooling roller B, keeping the latter clean and allowing the whole of the contents
of the tank A an opportunity of being acted upon by it.
Stuffing boxes or other means of preventing leakage are provided as at F where
the trunnions B' and shaft C pass through the walls of the tank A and where the
hollow shaft B3 passes through the trunnions B'.
If desired a heating medium may be delivered to the jacket A¹ and roller B
instead of the cooling medium.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what I
claim is:.
--
1. A cooler for chocolate or the like comprising a jacketted or other tank in
which a beater and a cooling roller operate in contiguity.
2. A cooler for chocolate or the like comprising a jacketted or other tank in
which a cooling roller provided with a scraper is employed for the purpose
5 described.
3. The complete cooler for chocolate or the like substantially as described or
illustrated in the accompanying drawings.
