IMPROVEMENTS IN FREEZING MACHINES to be as follows:
Year: 1884

page_text: PROVISIONAL SPECIFICATION.
I ALFRED WILLIAM MARSHALL of Mortimer Street, Cavendish -Square in the:
County of Middlesex, Tutor, do hereby declare the nature of said invention.for
"IMPROVEMENTS IN FREEZING MACHINES to be as follows:-
"
11.
Machines constructed according. to this invention are primarily intended for
domestic use, the object being to save time, labour and freezing material and to
simplify the construction and use of such machines. I construct, the machine.
in such manner, that the freezing pan or vessel containing the material to be.
frozen turns upon a central, upright pivot which is fixed to the bottom of the tub.
containing the freezing mixture and so that the freezing action, by preference
wholly or principally takes place from below, the freezing, pan being of large
diameter and shallow; also in such manner that the said pan can be easily removed
and replaced and also the state of the contents examined at a glance. A hollow
spindle fixed centrally in the bottom of the freezing pan and rising therein can
turn on the aforesaid pivot and the said pan can rise and fall on the central fixed
pivot as required according to the amount of freezing mixture contained in the tub
and under the bottom of the pan. The said hollow spindle with the pan is free to
turn in the mixer sleeve or boss which is held in place by being formed with a
square or flats at the top, on which square is fitted a corresponding. square hole
formed in a cross bar which fits easily in or on the upper part of the tub and is
prevented from turning therein by a peg or other stop in or on the tub. The pan'
is provided with a loosely fitting lid having a smaller lid which on being raised
or removed admits of ready inspection of the contents during the operation of
freezing. The. pan is turned by means of, a handle, fitting on the top of the
aforesaid hollow spindle. The position of the mixer sleeve and arms can be
adjusted vertically by means of a nut. Although I find it most convenient to
employ freezing mixture under the bottom of the pan only I may of course.if
desired pack it around the pan also.

I ALFRED WILLIAM MARSHALL of Mortimer Street Cavendish Square in the
County of Middlesex Tutor do hereby declare the nature of said invention for
IMPROVEMENTS IN FREEZING MACHINES
and in what manner the same is to
"
be performed, to be particularly described and ascertained in and by the following
statement:-
Machines constructed according to this invention are primarily intended for
domestic use, the object being to save. time labour and freezing material and to
simplify the construction and use of such machines, I construct the machine in such
manner that the freezing pan or vessel containing the material to be frozen turns
upon a central upright pivot which is fixed to the bottom of the tub containing
the freezing mixture and so that the freezing action by preference wholly or
principally takes place. from below, the, freezing pan being of large diameter and
shallow; also in such manner that the said pan can be easily removed and replaced
and also the state of the contents examined, at a glance.
And in order that my invention may be more fully understood; and readily.
carried into effect I will describe the same, with reference to the accompanying
drawings of which Figure 1 is a perspective view of an apparatus constructed
according to my invention, Figure 2 a vertical cross section, Figure 3. a horizontal
section on line X Y of Figure 2; Figure 4 being a. part. plan of a portion of
apparatus. A hollow spindle A fixed centrally in the bottom of the freezing pan B.
and rising therein can turn on the aforesaid pivot or spindle C and the said. pan B
can rise and fall on the central fixed pivot or spindle C as required according to
the amount of freezing mixture contained in the tub D under the bottom of the
pan B. As here shown the latter is in its lowest position but when in operation
and the freezing, mixture. is placed under it there will be a considerable space
between the bottom of the pan B and the tub D which space will contain the said
freezing mixture.

The said hollow spindle A with the pan B is free to turn in the mixer sleeve or
boss E which is held in place by being formed with a square or flats at the top, see
Figures 2 and 4 on which square is fitted a corresponding square hole formed in a
cross bar F which fits easily in or on the upper part of the tub and is prevented
from turning therein. by a peg G or other stop in or on the tub D. The pan B. is
provided, with a loosely fitting lid H having a smaller lid I which on being raised
or removed admits. of ready inspection of the contents during the operation of
freezing. The pan Cis turned by means of a handle K fitting on the top of the
aforesaid hollow spindle A. The position of the mixer sleeve E. and arms E! can
if desired' be made so as to be adjusted vertically by means of a nut. L is. a. plug
for draining the tub. Although I find it most convenient to employ freezing
mixture under the bottom of the pan only requiring no. packing or use of spatula.
I'may of course if desired pack it around the pan also.
The mode of using it is very simple. Some ice and salt is thrown in the bottom
of the tub D and some cream into the pan B., Then, turn the handle, for a few
minutes and the cream, is frozen. The state of the contents of the pan B can bo
ascertained from time to time by opening the lid I.
The whole operation is convenient quick and clean.
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
First A freezing machine consisting of a tub with fixed central pivot on which
the central hollow spindle of the pan can turn freely, the boss or sleeve of the 5

page_text: mixer being mounted freely on the said hollow spindle and provided with a bar
which comes against a stop in or on the tub substantially as described.
Second: A freezing machine consisting of a shallow tub D with fixed central
pivot C on which the central hollow spindle A of the pan B can be turned freely
by handle K, the sleeve or boss E of the mixer being mounted freely on the
spindle A and provided with cross bar F which comes against a stop G in or on
the tub substantially as shown on the drawing.
Dated this Seventh day of November 1884.
