Alfred William ADAMS, of Upper Ground Street, Blackfriars, in the County of
Surrey, Ice Manufacturer. "AN IMPROVED BOX OR MOULD TO BE USED IN CON-
NECTION WITH MACHINERY FOR MANUFACTURING ICE."
The object of my said Invention is the construction of a box or mould to be
attached to or employed in connection with machinery or apparatus for manu-
facturing ice. The said box or mould is designed to receive and hold the water
that is to be frozen or converted into ice so that the ice produced will be in blocks
of uniform shape and size, and easily and economically removable from the said box
or mould.
The novel and peculiar features of this Invention are the freezing of the water in
the said box or mould simultaneously at or from the bottom as well as at the sides
of the box or mould, and the formation of the said sides with a slope or inclination
downward and inward from the top to the bottom of the same, and in the applica-
tion of wood for the protection of the heads of the bolts used in the construction of
the said box so that no ice can form on the same.
The said box or mould is constructed preferably with an exterior portion of wood
and with an interior portion of metal forming a series of compartments or divisions
in which the ice is formed. This metal portion is constructed of thin cast iron or
other suitable metal, and in compartments with inclined or sloping sides and open
at the ends. The said inclined or sloping compartments are placed side by side in
the box or mould with a vertical partition plate in the centre of the space between
them. The said compartments have flanges all around their ends, that is to say, on
the sloping and upper and lower portions of their ends; the upper and lower portions
of these flanges are connected by vertical portions, which vertical portions are fitted
together with the said partition plates between them to form tight joints, and they
are secured by bolts or nuts passed through the said flanges and plate. The said
flanges form a recess around the bolt or rivet heads, and this recess is filled up with
wood or other suitable material upon which ice will not form. The spaco below the
said compartments and between the same and the said vertical partition plates
forms the passage for brine or other freezing fluid. The said passage by reason of
the flanged construction above described slighty.shorter than the spaces or com-

page_text: partments in which the blocks of ice are formed. Each of the said vertical plates
has a narrow aperture or slot through its upper portion to form a communication
between the spaces on each side of the said vertical plate, so that there will be a
continuous passage throughout the entire length of the box for the freezing fluid to
pass below and between the said compartments.
The said box or mould is preferably constructed with two series of the said par-
titions extending from end to end of the box, with a central space between them
and two side spaces. These central or side spaces, or both, are occupied by rockers
or agitators of any suitable form, and by whose action the ice formed in the said
compartments is rendered transparent.
The brine or other freezing liquid is caused to flow through the spaces below and
between the compartments as above described, and returns through a pipe or
passage below the box.
Or it may flow through the said spaces in one direction on
one side of the box and return through the said spaces on the other side.
My said Invention may be used in connection with any machine or apparatus for
making ice, and I can produce any given or determined quantity of transparent ice
of any desired thickness with the most advantageous utilization of the power of the
said machine or apparatus, and with the greatest economy with regard to the
materials used in the same.
