Improved Process and Apparatus for Obtaining Ice.
[A communication from HENRICH BECHMANN, of Bamberg, in the Kingdom of
Bavaria, Merchant.]
I, ALFRED JULIUS BOULT of 111 Hatton Garden in the County of Middlesex,
Chartered Patent Agent, 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:-
This invention relates to a process and apparatus for obtaining ice in which
finely atomised water is caused to be sprayed on to a framing or surface such for
instance as bars or laths arranged in parallel rows simply or cross-wise over one
another and covered, if desired, with mats or canvas, and is frozen to ice at a
suitable temperature. This ice can be produced on the above supports in any
desired thickness and the supports can be broken off in pieces of desired size, so
that this process has the advantage over the processes used hitherto first, that it
dispenses with complicated refrigerating machines producing more
poisonous ice, and also there is no possibility of breaking of vessels as in other
processes for freezing water.
or less
For the practical application of this process a frame a may be employed
consisting of one or more storeys, in which are loosely supported rods or the
like serving for catching the sprayed water. Between these rods b there is
generally left a free space in order to enable the excess of water spray to fall on to
the supports or bars below, in case there be several storeys one over the other. It
must be pointed out that according to the shape of the supports b-whether of
round or angular cross section, the ice forms only on the bars, so that after they
have been removed from the frame a the ice can be broken off only in small pieces.
If it is desired to produce flat and comparatively large pieces of ice, it is necessary.
to cover the bars 6 with a mat or the like; the falling water settles on the latter
uniformly over its whole surface and ice is formed which, when it has reached the
desired thickness can be readily removed from the mat.
In the accompanying drawings the apparatus is shown by way of example as
a two storey-frame, Fig. 1 being a front elevation in longitudinal section and
Fig. 2 a cross section.
At the top of the frame a there may be arranged one or more water supply
pipes c according to the output to be attained, said pipes being supplied from a
main water-supply pipe d provided with necessary cocks or valves as e and f.
Jn these pipes c there are preferably arranged at suitable intervals fixed or
movable roses or spraying devices g, water entering under suitable pressure and
then escapes as a fine spray, whereupon the ice is formed in the manner described.
In the accompanying drawing the roses 9 are shown arranged with their perfor-
ations upwards as by this means water falls naturally which is a considerable
advantage for the formation of ice.
Having regard to the fact that the process can be carried out only when the
surrounding air is at a suitable temperature, and that the frame a is accordingly
placed in winter in the open air and in other seasons in correspondingly cool
places, it is obvious that the water must be prevented from freezing in the pipes c
and d by suitably covering them.

page_text: Having now particularly described and ascertained the nature of the said in-
vention as communicated to me by my foreign correspondent, and in what manner
the same is to performed, I declare that what I claim is :-
1. A method of obtaining ice characterised by water being ejected in a finely
atomised or sprayed condition from perforated pipes, fixed or movable roses or the
like and falling on to bar, matting or the like arranged below, the operation
takin place at a suitable temperature substantially as described.
The combination and arrangement of parts constituting the complete
araratus for use in the production of ice, substantially as described and illustrated
in the accompanying drawings.
