JAMES ANTHONY GRAHAM, of Putney, in the County of Surrey, Chemical
Engineer. "IMPROVEMENTS IN MACHINES FOR PRODUCING ORNAMENTED SOAP,
APPLICABLE ALSO TO THE ORNAMENTATION OF OTHER PLASTIC MATERIALS."
My Invention relates especially to a die or mould for producing cakes, tablets,
or bars of soap, of two or more colours, but the same may be applied to other
purposes where it is required to have two or more different coloured plastic
materials combined, such for instance, as articles of clay, fancy biscuits, con-
fectionery, etc.
The soap or other plastic material which is to form the main body of the cake,
tablet, or bar is fed or forced into a tapered tube. Through this tapered tube
passes one or more smaller tubes which may have any suitable cross section, such
as a star or cross, or any other suitable form. One of the tubes may pass centrally
through the tapered tube, and a second one may envelop it, so that when the
three different supplies of soap or other material meet at or near the extremity of
the tapered tube, they will form a body of one colour having the form which is
given to the extremity of the outer or tapered tube, such as an oval or rectangle,
or other suitable form; an inner eye or part in the shape of a star or cross, or
other design or shape, according to the section of its tube, and of a different colour,
and also an intermediate part of a third colour which will have the form or shape
of its conducting tube. It is only necessary to give the required shape to the exit
end of the different tubes, the other part being formed so as to offer the least
possible resistance to the passage of the soap or other material round it.
It will be well understood that more tubes may be employed, one for each colour,
and they may have any suitable cross section and be arranged in any suitable
manner inside the outer tube. The surfaces of the inner tubes or parts thereof
may be in contact with the interior of the outer tube or with each other.
The various coloured soaps or other materials are fed to the die or mould by any
suitable forcing machinery, and upon issuing from the outer or tapered tube may
be cut off into cakes, tablets, or bars. The outer or tapered tube may be prolonged
for any suitable distance beyond the termination of the inner tubes when desired,
by means of additional, removable, or fixed tubes.

page_text: The different tubes may be surrounded by a jacket in which steam or any other
suitable heating or cooling medium may be caused to circulate so as to bring the
temperature of the surfaces of the different streams of material to the required
degree to ensure their proper adhesion at the point or points of contact. These
jackets may also be utilized in certain cases for conveying an adhesive or lubricating
material to the surfaces of the different streams of soap or other material which
are required to adhere, suitable openings being formed communicating with the
interior of the tubes.
In some cases several series of inner tubes may be arranged within the outer or
tapered tube so as to produce several cakes, tablets, or bars of various forms or
designs.
