An Improved Apparatus for the Rapid Formation of Ice for
Medicinal and other Purposes.
I BENNO MANFRONI, of 20 Amalienstrasse, Dresden, Saxony, in the Empire of
Germany, Confectioner, do hereby declare the nature of my said invention and in what
manner the same is to be performed, to be particularly described and ascertained in and
by the following statement :-
The object of my invention is to manufacture a new and improved apparatus for
preparing any kind of ice for medicinal and other purposes.
And in order that my said invention may be particularly described and ascertained,
reference is hereby made to the accompanying drawings, in which similar letters of
reference indicate corresponding parts.
Fig. 1 is a vertical section: Fig. 2 a horizontal section, on the line x x of Fig. 1,
and Fig. 3 is a top view.
The apparatus consists of an outer cylinder a¹ and an inner cylinder a² the space a
between these two cylinders is filled with any suitable non-conducting material. In
the centre of the apparatus the cylinder b is fitted, in which cylinder the substance to
be frozen is placed. The cylinder b is provided with a cover c, fitting the cylinder
closely. A bar d is attached to the cover c, the bar having a square hole at g for the
insertion of the square end of the pin
axle n are supported by the bracket i to
geared to the pinion h, and both pinions
The lower end of b is fitted with a pin
or case 8.
carrying the pinion h. The handle m and
which the pinion o, is fitted, the pinion o being
being encased in k, supported by the cover i.
working in a hole in the perforated cylinder
The spacer, between the cylinder a² and the perforated cases, is filled with pieces
of ordinary ice and salt, the openings e, e, being provided for that purpose.
On turning the handle m the cylinder b is caused to rotate, and the greater the speed of
rotation the shorter will be the time consumed in freezing the substance under treatment.
The apparatus is nickel plated outside, and tinned inside in order to protect it from
oxidation. The cylinder 6 may be made of porcelain (if preferred) and the materials
and details of construction may also be varied.

page_text: My invention is chiefly designed for medicinal purposes, and, by its use, patients
may be speedily provided with clean ice. Also various additions may be made to the
substance to be frozen, according to the Physician's directions.
Tea heated to a temperature of 40° Cent., and poured into the apparatus, can be
frozen in three minutes. Also all kinds of fruit ice may be obtained in from two to
three minutes; and the frozen mass remains in that state in the Cylinder for nine hours
or thereabouts.
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 method of producing various kinds of ice, by means of the rotating
cylinder b, enclosed in the perforated cylinder s, the latter being surrounded by a mass
of ordinary ice and salt, and further enclosed in a non-conducting jacket a,
substantially as hereinbefore described and shewn on the drawings.
2. The general construction combination and arrangement of the several, and
respective parts, together constituting my invention of an improved apparatus for the
rapid formation of ice for medicinal and other purposes substantially as hereinbefore
described and shewn on the drawings.
