Improvements in or connected with Soap Tablets for Toilet or other
purposes.
I, CHARLES LARUE, of 52, Rue Lebeau, Brussels, in the Kingdom of Belgium,
Merchant, 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 thereof, that is to say :-
The device which forms the subject of this invention is a core constructed
in any desired form to be introduced, in the process of manufacture, in the centre
of cakes of soap. This is accomplished by providing the machine generally
known by the name of soap squeezer" with a spindle preferably. of elliptical
section projecting from the grating and so situated that it will occupy the centre
of the draw plate.
This spindle, which may take any desired shape, would leave a hollow corre-
sponding to its shape in the centre of the mass of soap, this hollow would itself
correspond to the shape of the core so as to receive said core which is placed
therein by hand or otherwise before the moulding of the tablets of soap, the core,
embedded in the centre of the latter, constituting there a solid body having for
its object:-
1stly to effect an economy as much to the manufacturer as to the consumer.
2ndly to keep the cake quite whole until it is completely used.
3rdly to render the use of tablets of soap more practical.
And in order that the said invention may be clearly understood I will proceed
aided by the accompanying drawings fully to describe the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a plan of a round convex core constructed according to the present
invention.
Figure 2 is a plan of an oval convex core.
Figure 3 represents a section of the cores shown in Figures 1 and 2 and
Figure 4 is a sectional view of part of a soap squeezing machine showing the
mechanism for carrying the invention into effect.
Referring to Figures 1 to 3 of the drawings which are made to approximately
full size, AA are holes which may be varied in shape, size, number and position.
The shapes in Figures 1 and 2 correspond to those which the cakes or tablets
usually take and preserve until the time when they become almost beyond use
and frequently break and become difficult to manage.
Figures 1 and 2 are evidently susceptible to variation of shape and dimensions
so as to correspond with those given to tablets of soap by manufacturers, for
example it is evident that a spherical cake of soap should enclose a similarly
spherical core.
The object of the holes A is to allow the plastic material to pass through the
core when the cake or tablet is being moulded and so as to cement together the
mass of soap existing on either side of the core.
Referring to Figure 4 which illustrates the mechanism employed in carrying

page_text: the invention into effect C represents a spindle of elliptical section or it might
be of other suitable form fixed with the usual grating B axially of the die D..
The mass of soap as it is pressed through the grating B and die I) is by the
spindle C formed into a rod of tube like section and is cut off into the required
lengths by hand or otherwise after which the lengths are moulded into tablets
in the usual way.
By means of the present invention the form of the soap tablet is preserved
until the last and every particle thereof is utilized instead of the last part being
wasted as heretofore.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is:
1. A core to be introduced during the process of manufacture into the centre
of tablets of soap, said core being of any suitable shape and dimensions and
provided or not with holes of any shape, size, position and number substantially as
herein shown and described.
2. A soap cake or tablet formed with a central core substantially as herein
shown and described.
