woning Liquids.
I, THOMAS GRAYSON, of 16, Queen Street, Derby, in the County of Derby,
Sheet Metal Worker, do hereby declare the nature of this invention to be as
follows:-
My invention relates to an improved means for cooling liquids, and has for
its object to more effectually reduce the temperature of the liquid while under-
going the process of cooling with the use of less water for this purpose (relatively
to the size of refrigerator being employed) than has hitherto been the case.
My invention consists of arranging in the trough or receiver of the refrigerator,
one two or more coils of tubing through which the cold water is continually
passing instead of finishing off the coil below the said trough or receiver as at
present in vogue, the water outlet being elevated above the ordinary horizontal
position in order to permit the last coil of tubing to be always full of water,
thereby ensuring the cooling of the liquid commencing immediately the same
has been placed in the trough or receiver instead of requiring to wait until the
liquid has percolated through the said trough or receiver onto the cooling coil.
Dated this 25th day of July 1899.
I, THOMAS GRAYSON, of 16, Queen Street, Derby, in the County of Derby-
shire, Furnishing Ironmonger, 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:-
My invention relates to an improved means for cooling liquids, and has for
its object to reduce the temperature of a maximum quantity of milk, beer, or
other hot liquid with the use of a minimum quantity of cold water, relatively
to the size of the refrigerator employed, and as compared with such refrigerators
as hitherto made and used.
In order that my invention may be more readily understood I have hereunto
appended a sheet of drawings, in which,
Fig. 1 represents in side elevation a refrigerator to which my said invention
has been adapted.
Fig. 2 is a sectional elevation taken upon the line A B and viewed from left
to right of Fig. 1.
Fig. 3 is an end elevation viewed from left to right of Fig. 1 while
Fig. 4 is a plan view of the said refrigerator, as illustrated in the preceding
figures.

page_text: In carrying my invention into effect I construct of any suitable material a
pair of side plates or supporting standards A B, between which, and extending
almost from the top to the bottom of same, is suitably connected the usual corru-
gated water passage and cooling surface C, above which is arranged the refrigera-
tor trough or receiver D, and below the said corrugations C is situated the bottom
trough for delivery of the liquid after cooling.
My invention consists in so continuing or extending the water passage and
cooling surface C, that a coil or length of tubing F (preferably the latter as
shewn) is situated in, and 'extends the whole length of the said trough or
receiver D), Figs. 2, 3 and 4, in lieu of finishing off the corrugations C below D
as heretofore, the water-outlet G being elevated above the tube F in order to
permit the said tube to be always full of water,, as hereinafter explained.
In operation, a continuous current of cold water is passing from the water
inlet H to the water outlet G, through the corrugations C and tube F, while
simultaneously therewith the liquid to be cooled is fed into the receiver or
trough and percolates therefrom through the apertures J in the lower, sur-
face of 1), over and down the outer surfaces of the corrugations C, in the.. usual
way, at the bottom of which it is collected in the trough E, and conveyed by
means of an outlet K to where required.
Immediately the liquid is placed in the trough or receiver D, it must
necessarily cover the outer surface of the tube F, which is always completely
filled with cold water by reason of the water outlet G being elevated above the
said tube F, and consequently instead of the liquid having to percolate through
the perforations or apertures J in the trough or receiver D) on to the cooling coil
or surfaces C, before the cooling effect commences, the same is attained directly
the liquid is fed into the trough or receiver D).
Or in lieu of the tube F in the trough or receiver D, I may provide that the
corrugations C be extended through the said trough or receiver D and therein
situated in the form of a spiral coil, the operation of the apparatus being pre-
cisely the same as before, the only noticeable difference being that a somewhat
larger cooling surface is obtained by reason of such spiral ending to the corru-
gations C.
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:-
1st. In a refrigerator for cooling liquids, the employment of a water tube
or coil in the receiving trough, substantially as and for the purposes stated.
2nd: The improved means for cooling liquids, consisting of the combination
with a refrigerator such as A B C having a receiving trough such as D), of a
tube or coil such as F', placed within the said trough D and forming part of the
cold water passage, substantially as and for the purposes herein set forth and
shewn.
3rd. In an improved refrigerator for cooling liquids, the combination of a
pair of standards A B, supporting an upper trough 1), and lower trough E, with
outlet K, and a cold water course formed by a zigzag passage C, the said passage
commencing at an inlet H, and terminating in a tube or coil F standing up
within the trough 1), and exhausting through a pipe G at a point above F', sub-
stantially as and for the purposes herein set forth and shewn.
Dated this 31st day of October 1899.
