Improvements in Freezing Machines.
I, JOSEPH WILLIAM FROUD of Hawthornden, Dagnall's Park, South Norwood in
the County of Surrey, Gentleman, do hereby declare the nature of said invention to
be as follows:-
The invention has for its object improvements in freezing machines.
For this purpose I employ a tub or container for the freezing mixture and a vessel
within which the matter to be frozen is placed as heretofore but instead of mounting
the freezing vessel vertically I place it at an angle or in an inclined position and
I form the same of a gradually increasing diameter from the bottom to about mid way
of its length in order that in revolving its lower side may assume a position parallel or
nearly so with the bottom of the tub.
The tub is provided with a guide leading to a footstep or bearing for a stud or axis
carried by the lower part of the freezing vessel or such footstep or bearing may be
used without the guide and the freezing vessel at its upper part or lid is fitted with a
stud carrying a cross-pin which is capable of engaging with a hook carried by a shaft
which receives motion from a clockwork apparatus.
Or any other suitable form of coupling may be employed to connect the freezing
vessel with such shaft and to enable the same to be readily disconnected and removed
from the tub.
The clockwork apparatus which may be of any ordinary construction is carried by
a bracket which may be permanently or removeably connected with the tub or
container.
By these means the freezing vessel is gradually revolved and a fresh part of the
contents thereof continuously and evenly presented to the action of the freezing
mixture without the necessity for revolving the freezing vessel or stirring its contents
by hand as heretofore.

I, JOSEPH WILLIAM FROUD of Hawthornden Dagnall's Park, South Norwood, in
the County of Surrey, Gentleman, do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
The invention has for its object improvements in freezing machines.
For this purpose I employ a tub or container for the freezing mixture and a vessel
within which the matter to be frozen is placed as heretofore but instead of mounting
the freezing vessel vertically I place it at an angle or in an inclined position and
I form the same of a gradually increasing diameter from the bottom to about midway
of its length in order that in revolving its lower side may assume a position somewhat
approaching to parallel with the bottom of the tub.
The tub is provided with a guide leading to a footstep or bearing for a stud or axis
carried by the lower part of the freezing vessel or such footstep or bearing may be
used without the guide and the freezing vessel at its upper part or lid is fitted with a
stud carrying a cross pin which is capable of engaging with a hook carried by a shaft
which receives motion from a clockwork apparatus.
Or any other suitable form of coupling may be employed to connect the freezing
vessel with such shaft and to enable the same to be readily disconnected and removed
from the tub.
The clockwork apparatus which may be of any ordinary construction is carried
by a bracket which may be permanently or removeably connected with the tub or
container.
And in order that my said invention may be more clearly understood and readily
carried into effect I will proceed aided by the accompanying drawings more fully to
describe the same.
DESCRIPTION OF THE DRAWINGS
Figure 1 is an elevation partly in section representing my improvements in freezing
machines. Figure 2 is an interior view of part of the tub showing the guide herein-
after described. Figure 3 is partially a section and partially an elevation of the upper
part of the freezing vessel. Figure 4 is an elevation of part of the tub with the
clockwork apparatus in position. Figure 5 is an underside view of the clockwork
apparatus with the cover partly broken away. Figure 6 is a cross section and
Figure 7 is an end view of the same.
In all the figures like parts are marked with similar letters of reference.
Figures 5, 6 and 7 are drawn full size, Figures 1 to 4 are drawn half size.
I employ a tub or container a for the freezing mixture and a vessel b within which
the matter to be frozen is placed, as heretofore, but instead of mounting the freezing
vessel vertically I place it at an angle or in an inclined position and I form the same

page_text: of a gradually increasing diameter from the bottom to about midway of its length in
order that in revolving its lower side may assume a position somewhat approaching to
parallel with the bottom of the tub a.
The tub a is provided with a guide c leading to a footstep or bearing c² for a stud
or axis b¹ carried by the lower end of the freezing vessel or such footstep or bearing cl
may be used without the guide c and the freezing vessel 6 at its upper part or lid is
fitted with a stud or projection 6 carrying a cross pin 6 which is capable of engaging
with a hook d' carried by a shaft d which receives motion from a clockwork apparatus
contained in the case e.
Or any other suitable form of coupling may be employed to connect the freezing
vessel with such shaft d and to enable the same to be readily disconnected and
removed from the tub a.
The clockwork apparatus in the case e may be of any ordinary construction, that
represented in the drawings being found to answer well, it is wound up by the
handle and is stopped by means of the screw g acting against the fly h or started by
withdrawing the screw from such fly.
The clock-work case e is carried by a bracket i which may be permanently con-
nected with the tub or container a as shown or may be removeably connected
therewith.
The clock-work case e fits within the bracket i and it has two lugs or projections e¹
which pass into slots in the upper part of the bracket to hold the clockwork securely
in position on the bracket.
The lid 6 of the freezing vessel fits tightly on to the mouth of the latter but in
order to prevent the possibility of its slipping when revolved by the clockwork I form
the rim of the lid with a notch ' to receive a stud or block 6 on the mouth of the
vessel b.
By these means the freezing vessel is gradually revolved and a fresh part of the
contents thereof continuously and evenly presented to the action of the freezing
mixture without the necessity for revolving the freezing vessel by hand as heretofore.
I would here remark that I have not thought it necessary to give a description of
the details of construction of the clockwork apparatus as such will be readily under-
stood from an examination of the drawings and separately considered it forms no part
of my present invention.
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 :-
1. The arrangement and combination of parts whereby the freezing vessel may by
the aid of clockwork be revolved within the tub or container and may be readily
connected and disconnected with the clockwork and placed in position and removed
from the tub or container substantially as herein shown and described and for the
purpose stated.
2. The arrangement and combination of parts whereby the freezing vessel is
supported at an angle in suitable bearings and rotated either by clockwork or other-
wise substantially as herein shown and described and for the purpose stated.
