PROVISIONAL SPECIFICATION.
Improvements in Rotary Freezers.
I, ADELAIDE BRUNETTI, of No. 242, Vauxhall Bridge Road, in the Administrative
County of London, married woman, do hereby declare the nature of this invention
to be as follows:-
My invention relates to Improvements in Rotary Freezers, and has more particular
reference to the position of the driving gear.
In rotary freezers of the usual construction, the gearing is at the top of the freezer,
and is removable with the cover. It must also be properly adjusted after each
removal of the cover before the freezer can be worked.
Now according to my invention, I discard the usual gearing and provide a vertical
spindle adapted to rotate in a bearing in the bottom of the ice pail. The top of the
spindle is conical, and the foot of the freezing vessel adapted to fit thereupon.
The spindle passes downwards through the bottom, and suitable gearing is provided
by which it can be rotated by a crank handle on the outside of the pail. This gearing
is preferably concealed by a suitable casing. If the freezer is to be driven by power
other than hand, the gearing is modified accordingly. A ring guide is provided to
embrace the top of the rotating freezer and prevent it from being thrown off its seat
by centrifugal energy.
Suitable tallow or other packings or stuffing box devices are used to keep the
spindle bearing water tight.

COMPLETE SPECIFICATION.
Improvements in Rotary Freezers.
I, ADELAIDE BRUNETTI, of No. 242, Vauxhall Bridge Road, in the Administrative
County of London, married woman, 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 Improvements in Rotary Freezers, and has more particular
reference to the position of the driving gear.
In rotary freezers of the usual construction, the gearing is at the top of the freezer
and is removable with the cover, It must also be properly adjusted after each removal
of the cover before the freezer can be worked.
Now according to my invention, I discard the usual gearing, and provide a vertical
spindle adapted to rotate in a bearing in the bottom of the ice-pail, and to carry the
freezer proper. The spindle passes downwards through the bottom of the pail, and
suitable gearing is provided by which it can be rotated. This gearing is enclosed
within a suitable casing, a part of which forms the base of the freezer.
In order that my invention, and the means by which the same is to be carried into
practical effect, may be thoroughly understood, I will now describe them in detail,
referring in so doing to the accompanying figures which are to be taken as part of
this specification and read therewith.
Fig. 1 is a sectional longitudinal elevation.
Fig. 2 is a plan, omitting the cover of the freezer proper.
A is the ice pail fast upon the base B of the freezer. The base is hollow and, with
the box C, forms the casing for the gearing.
D is is a crank handle; and E, the first motion shaft upon the end of which it is

page_text: fixed. F, Fare grooved pulleys, the former on the shaft E, and the latter upon the
lower end of the vertical spindle G. H is the driving cord. I is a guiding pulley.
J is a tightening pulley carried by a frame j which is movable in either direction in
guidesk, k by the adjusting screw L.
M is the freezer proper. The bottom of it is extended downwards externally, and
has a cavity formed in it, whereby it is adapted to fit tightly upon the spindle G.
Both are, preferably, tapered, and, in plan, either square or triangular, so that the
freezer must revolve with the spindle. N is a stuffing box provided for the purpose
of packing the spindle G water-tight. O is the waste for drawing off the water.
is a circular guide within which the freezer M rotates. This guide is kept in
position by arms p which engage in sockets q. A locking pin or pins, 7, are provided.
These are passed through holes in the respective arms and sockets as indicated in
Fig. 2.
s is a ring fast upon the freezer. It function is to prevent the freezer being
forced upwards.
The gearing represented may be modified, or replaced by gearing of any other
suitable type.
Any number of freezers may be driven from one shaft. They would then be
preferably arranged round the pulley F, and all be driven by one cord.
The tightening device is required only when the driving band or cord is used is
liable to be stretched.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
1. The combination of rotary freezer, spindle, and fixed ice pail, as and for the
purpose set forth.
2. The combination of rotary freezer, gearing-casing, and concealed gearing, as set
forth with reference to the accompanying figures.
