PROVISIONAL SPECIFICATION.
Improvements in Freezing Machines for Manufacturing Ice Creams
and the like.
I, FREDERICK John Burrell, of Saint Nicholas Works, Thetford, in the
County of Norfolk, Engineer, do hereby declare the nature of this invention to be
as follows:-
•
I utilize a revolving cylinder of metal or other suitable material situated so as to
revolve on a horizontal axis. This cylinder is hollow and contains the freezing
mixture which may consist of ice, salt, or other materials. This cylinder is
situated in a box the bottom of which forms a receptacle for the cream or liquid
which is to be frozen. In order that the said liquid may be applied to the surface.
of the cylinder in a thin and uniform manner I utilize a band or belt of canvas or
other suitable material running over rollers or otherwise. This band comes in
contact with the surface of the revolving cylinder and being caused to travel in the
same direction or otherwise as that portion of the cylinder next which it is in
contact, the lower portion of the said band is caused to pass (or a fixed metal hoop
or band) along the bottom of the receptacle containing the cream or liquid to be
frozen. The rollers on which the band travels may be either caused to rotate by
belt, gearing, or other suitable means, or the belt may be caused to travel by the.
weight of the cylinder resting upon it. In order to collect the ice which gathers
upon the cylinder as the liquid becomes frozen I utilize a scraper and that the
outside surfaces of the cylinder shall not be acted upon by any acids in the liquid
I cover the cylinder with a coating of nickel preferable electro deposited, or the
walls of the cylinder may be made of aluminium. The scraper which is caused to
press against the surface of the cylinder is also made of aluminium or some such
metal that it is not acted upon by acids. The cylinder may be caused to rotate by
hand or other suitable means.
-
It will be understood that the foregoing is given by way of illustration, and that
the shapes materials and proportions of the parts, inay be varied in many ways
within the scope of my invention.

COMPLETE SPECIFICATION.
Improvements in Freezing Machines for Manufacturing Ice Creams
and the like.
I, FREDERICK JOHN BURRELL, of Saint Nicholas Works, Thetford, in the
County of Norfolk, Engineer, 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 freezing machines for manufacturing
ice creams and the like.
And in order that my invention may be thoroughly understood, I now proceed
to describe the accompanying drawing thereof, reference being had to letters and
figures marked thereon.
Fig. 1. is a vertical section of the apparatus.

page_text: DESCRIPTION OF DRAWINGS.
A. cylinder containing the freezing mixture.
B. receptacle or tank into which the cream or liquid to be frozen is poured.
C. revolving band resting upon the top of cylinder A and kept in position by the
rollers G which are supported by the spring H.
D¹, D are rollers over which the band M is caused to pass.
The band M comes in contact with the under side of the cylinder A and picks
up the liquid to be frozen from the tank or receptacle B. The band M may be
driven by the friction of the cylinder A resting upon it or through a belt Ñ or
other suitable gearing.
E. is the scraper which takes off the frozen mixture from the surface of the
cylinder A and deposits it in the box F.
In Fig. 2, the band C takes up the liquid from the tank B,and transfers it in a
film to the outside of the cylinder A. To prevent the outside of the band C
becoming coated with ice the outside may be covered with a layer of wood or some
such material as may be a bad conductor of heat, or the band C may be made of
wood or non-conducting material strengthened or held together by bands or hoops.
The liquid to be frozen enters the interior of the band C at each end and is carried
upwards in the direction of the arrows when the handle L is turned.
The tray F is pushed into its place end wise through an opening in the side of the
box P. The cream or mixture, to be frozen is poured into the tank B at the
opening K.
All metal in contact with the cream or liquid to be frozen to be nickel plated or
of aluminium or such metal as is not acted upon by acids.
Radial dividing ribs are placed on the inside of cylinder A to insure ice
rotating and transmitting cold to walls of cylinder.
It will be understood that the foregoing is given by way of illustration and that
the shapes, materials and proportions of the parts, may be varied in many ways
within the scope of my invention.
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. In freezing machines for manufacturing ice creams and the like, the
combination of the handle L freezing cylinder A belt N band M and rollers D'
and D in tank B, with the scraper E tray F fitted in a box P with opening K,
substantially as herein described and according to Fig. 1, of the accompanying
drawing.
2. In freezing machines for manufacturing ice creams and the like, the
combination of the handle L freezing cylinder A scraper E revolving band C
tray F rollers G spring H tank B with the box P and opening K, substantially as
herein described and according to Fig. 2, of the accompanying drawing.
3. The radial dividing ribs on inside of cylinder A to insure ice rotating and
transmitting cold to walls of cylinder, substantially as herein described and for the
purpose specified.
