Improvements in Apparatus for Cooling Liquids,
I, JAMES THOMAS BENTLEY, of Circleville, Ohio, U.S.A., Inventor, do hereby
declare the nature of this invention to be as follows:-
The object of this invention is to provide an apparatus for cooling liquids, but
more especially milk, more rapidly than has heretofore been possible. Moreover,
by the use of my improved cooler, the liquid is cooled in an air-tight manner
and permits of the much desired process of cooling milk or cream without exposing
it to the air between any two extremes of temperature.
The invention comprises a suitable framework supporting a receptacle capable
of being closed by a lid if desired.
A coil of pipe is arranged within the receptacle, and is divided from the centre
part of the receptacle by a wall of wire or other suitable netting.
A rock-shaft is journalled in suitable standards on the sides of the receptacle
and has a blade or arm depending from it and extending into the receptacle.
The upper end of the blade is connected, by a pitman, to a crank, which recipro-
cates the blade or agitator.
The crank-shaft is driven by a band and pulley connecting it with the drive-
shaft, by which suitable pumps are driven to force the liquids through the coil
of pipe.

Improvements in Apparatus for Cooling Liquids.
I, JAMES THOMAS BENTLEY, of Circleville, Ohio, U.S.A., Inventor, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to certain new and useful improvements in cooling
apparatus designed for rapidly cooling milk, cream, and other liquids from any
degree of heat down to any temperature desired, without exposure, and especially
following any process of pasteurization or sterilization, and also for cooling cream
as it comes from factory separators or as it is delivered from cream haulers etc.
Reference being had to the drawings hereunto annexed,

page_text: Fig. 1 is a perspective view, partly in section, of my improved cooling apparatus,
and Fig. 2 is a 'plan thereof.
The apparatus comprises a preferably rectangular or. other shaped receptacle 1
supported by standards 2.
Within the receptacle is a coiled pipe 3, the upper end of which extends
upwardly, as shewn at 4, and is connected by pipes 5 and 6 to a suitable pump 7
connected to the suction pipe S. The lower end of the coiled pipe terminates
in outlets 9, 10, from which the cooled liquids can be conveyed to vats or the like.
Within the coil of pipe 3 is a perforated screen 11 to prevent the cooling mixture
from collecting between the coils.
An agitator 12, for stirring the cooling mixture, is mounted upon a shaft 13
supported in standards 14 and adapted to be rocked by a pitman 15 connecting
it with a crank 16 journalled in supports 17 and rotated by the belt pulley 18
deriving its motion from the pulley 19 on the pump and drive shaft 20, upon
which are also the fast and loose pulleys 21; the shaft being supported by the
pump and a suitable bracket 22.
A water pipe 23 and a steam pipe 24 to the vertical part 4 of the coiled pipe 3
and are fitted with suitable cocks 25, 26.
In operation, ice, or ice and salt, or other freezing mixture is placed within
the screen 11 and stirred more or less-according to the degree of cold required
by the agitator 12. The liquid to be cooled is drawn into and caused to circulate
through the coiled pipe 3 to the outlets 9, 10. After use, the pipes can be
cleaned and sterilized by water and steam admitted through the pipes 23, 24.
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:
The herein described apparatus for cooling liquids, consisting of a suitable
receptacle containing a coiled pipe having its lower end connected to suitable
outlet pipes and its upper end to a pump and suction tube, a perforated screen
surrounding the inner surface of the coil, and an agitator arranged to operate
within the perforated screen, and means for admitting steam and water to the
pipes for cleansing and sterilizing the same, all substantially as and for the
purposes herein before set forth and illustrated in the drawings hereunto annexed.
