AN IMPROVEMENT IN THE MANUFACTURE OF ICE
Year: 1885

page_text: I CHARLES DENTON ABEL of No 28 Southampton Buildings, Chancery Lane in
the County of Middlesex, Consulting Engineer and Patent Agent do hereby declare
the nature of my invention for "AN IMPROVEMENT IN THE MANUFACTURE OF
ICE" to be as follows:-
In the manufacture of ice in slabs, which are formed in removeable moulds
placed vertically in cold brine or other congealing liquid, it is difficult to obtain
the clearness and transparency that are desirable. Attempts have been made to
secure these qualities by agitation of the water while it is freezing, but it has been
found difficult to maintain the required agitation up to the solidifying point. This
invention relates to means of securing clearness and transparency of slab ice in
the following manner. The mould has at each end of it a part protected by an
external or internal lining of wood or other imperfectly conducting material, this
protected part having in it a vertical pipe which has numerous lateral perforations,
or forming a chamber parted off from the body of the mould by a vertical partition
having numerous perforations through it. From the perforated pipe or chamber
at the one end of the mould water is withdrawn by means of a rotary or
reciprocating pump or injector or other motor, and transferred through an external
channel to the pipe or chamber at the other end of the mould, so that there is a
flow, which may be continuous or intermittent, in a horizontal direction, from the
one end of the mould to the other. The inlet and outlet pipes or chambers of a
number of moulds may be connected to one motor which maintains the flow
through all of them simultaneously. Or the water drawn from the outlet of one
mould may be sent to the inlet of the next and so on-the water withdrawn from
the last being sent back to the first in order. As the water in cooling tends to
deposit matters held in solution, it is preferred to provide, in some convenient part

water passes slowly, so that the deposited matters may subside therein. As the
ice is imperfectly formed in the protected parts at the ends of the moulds, these
parts are cut or broken from each slab when it is taken out of the mould.

I, CHARLES DENTON ABEL, of No 28 Southampton Buildings, Chancery Lane, in 1
the County of Middlesex, Consulting Engineer and 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 ascertained in and by the following
statement :-

difficult to maintain the required agitation up to the solidifying point. This
invention relates to means of securing clearness and transparency of slab ice in the
following manner.
The mould M as shown in longitudinal section at Fig. 1 and in plan at Fig. 2
has at each end of it a part m protected by an external or internal lining of wood
or other imperfectly conducting material, these protected parts having in them
vortical pipes P1 P' which have numerous lateral perforations; or as shewn in

perforated pipe P³ or chamber C at the one end of the mould, water is withdrawn
by means of a rotary or reciprocating pump or injector or other motor, and
transferred through an external channel to the pipe P² or chamber C² at the other
end of the mould, so that throughout the entire depth of the mould there is a flow,
which may be continuous or intermittent, in a horizontal direction, from the one
end of the mould to the other, as indicated by the arrows. The inlet and outlet
pipes or chambers of a number of moulds may, as illustrated by Fig. 5, be
connected to one motor F which maintains the flow through all of them
simultaneously. Or the water drawn from the outlet of one mould may be sent to
the inlet of the next and so on, the water withdrawn from the last being sent back
to the first in order. As the water in cooling tends to deposit matters held in
solution, it is preferred to provide in some convenient part of the circuit that is

the water passes slowly so that the deposited matters may subside therein. As the
ice is imperfectly formed in the protected parts at the ends of the moulds, these
parts are cut or broken from each slab when it is taken out of the mould.
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
The herein described method of obtaining clearness and transparency of slab ice
by determining during congelation a horizontal flow of the water throughout its
whole depth from one end of the mould to the other.
