PROVISIONAL, SPECIFICATION.
An Improved Construction of Refrigerator or Cooling Pan for
Chemical and other Purposes.
We JouN DAWSON, of Kirkheaton Colour Works Kirkheaton, Huddersfield
Yorkshire, Manufacturing Chemist, and JOHN WILLIAM HAMPSON, of Macaulay
Street Huddersfield aforesaid, Drysalter, do hereby declare the nature of this
invention to be as follows:-
Our invention relates to refrigerators or cooling pans employed for cooling
chemical or other liquids or substances. Cooling pans have hitherto been formed
circular in horizontal cross section, but according to our invention we propose
to make such cooling pans corrugated in cross section so as to give increased
cooling surface to the liquor or mixture contained therein. The ordinary revolving
agitator may be circular as hitherto.
By forming the cooling pan corrugated, considerably more cooling surface is
presented to the substance under treatment.

COMPLETE SPECIFICATION.
An Improved Construction of Refrigerator or Cooling Pan for
Chemical and other Purposes.
We, JOHN DAWSON of Kirkheaton Colour Works, Kirkheaton, Huddersfield,
Yorkshire, Manufacturing Chemist, and JOHN WILLIAM HAMPSON of Macaulay
Street, Huddersfield aforesaid Drysalter, 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 :-
Our invention relates to refrigerators or cooling pans employed for cooling
chemical or other liquids or substances. Cooling pans have hitherto been formed
circular in horizontal cross section, but according to our invention we propose to
make such cooling pans corrugated so as to give increased cooling surface to the
liquor or mixture contained therein.
Such being the nature of our invention we will make reference to the accom-
panying sheet of drawings, wherein
Fig. 1 is vertical section and Fig. 2 cross section of our improved construction
of refrigerator or cooling pan.
A represents an ordinary form of wood cistern, in the middle of which we place
the refrigerator 13 formed of corrugated sides or with flutings as clearly shewn in
cross section in Fig. 2. Within the centre of the refrigerator, there is an ordinary
revolving agitator C for stirring or agitating the liquids contained. Cold water may
be entering into the wood vessel A and overflowing at any convenient point, so
that the water in the vessel is being continuously changed for cooling purposes.
By forming refrigerators or cooling pans with corrugated sides a considerably
larger cooling surface is presented to the liquids or substance under treatment, than
is the case when the refrigerator is a true circle.
The corrugated cooling pan may be used without the cold water cistern and
agitator.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that we
claim, is :-
The construction of refrigerators or cooling pans with corrugated sides,
substantially in the manner shewn and for purposes described herein.
Dated this 27th day of February 1892.
