Improvements in the Manufacture of Scented, Antiseptic, Medicinal
or Multi-coloured, or Variegated Soap, and in Machinery or
Apparatus therefor.
I, PAUL VILLAIN, of 24, Lovely Lane, Warrington, in the County of Lancaster,
Chemist, Soap Maker, and Perfumer, do hereby declare the nature of this invention
to be as follows:-
This invention has for its object a method of forming scented antiseptic and
medicinal soaps, whereby the scent antiseptic or chemical is more completely held
in the soap and allowed to more gradually exude from it than has heretofore been
possible. My invention also gives the advantage of enabling the soap to be more
bulky right down to the very last piece than heretofore. In the manufacture of
scented soaps at the present time they are mixed with the scent in a plodder or
boudoneuse. Now soap made in this machine will after a short time lose its scent
owing to the scent evaporating, and the principal part of my invention consists
essentially in placing this scent antiseptic or medicinal matter in the centre of the
soap and in machinery for accomplishing this object, whereby the chemical or
scent has to pass through a deep layer of soap and consequently is longer in
exuding from it.
At
I use the ordinary plodder, but with a different nozzle or delivery portion.
the end of the helical screw I place a transverse plate perforated with very
numerous small holes. This acts as an impediment to the soap and enables the
pulverulent soap to coalesce and form numerous strings or bars which proceed
towards the nozzle. To the centre of this plate I fix a long spike projecting out
through the centre of the nozzle and at the nozzle reduce the area so that all these
separate bars coming from the perforated plate are again forcibly united into a
tube round the spike. This tube is cut transversely into pieces of the requisite
size and a little boat or box of cedar wood or other suitable material filled with
the scent antiseptic or medicinal matter is placed in the centre of the tube. The
ends are now pinched up and the whole pressed into a cake, thus forming a solid
cake with the wooden nucleus in the centre containing the scent. The scent now
gradually percolates through. Instead of the boat of scent or the like a different
coloured soap can be placed inside the tube and the tube can be formed of any suit-
able contour inside or out by changing the spike or nozzle and placing a spike or
nozzle of equivalent contour. In this way several concentric tubes and a solid
rod of soap of different colours can be formed into one solid bar the smaller thick-
nesses being pressed into the larger ones preferably after being cut up or cut into
pieces afterwards transversely and these stamped into shape. By this means
stars and other forms can be made of one colour in a soap of another colour and the
star or other form will go right through.

I, PAUL VILLAIN, .of 24, Lovely Lane, Warrington, Lancashire, Soap
Maker, 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:
-
.
This invention has for its object a method of forming scented antiseptic and
medical soap, in such a manner that the scent or perfume, or the antiseptic or
chemical reagent is more completely held in the soap and allowed more gradually
to exude from it than has heretofore been possible."
My invention also gives the advantage of causing the piece of soap to be more
bulky down to the very last layer of soap in the piece.

In the manufacture of scented soaps as at present conducted, the said soaps are
mixed with the scent in a plodder or boudineuse" but soap thus prepared
loses its perfume in a short time, owing to the evaporation of the scent or the like
and the principle part of my invention consists in placing this scent or perfume or
antiseptic or medical matter in the midst of the soap; it further consists in the
construction of suitable machinery for accomplishing this object whereby, the
chemical or scent of the like has to pass through a deep layer of soap and con-
sequently is longer in escaping from it.
I desire it to be understood that by the term "scent" used above I include any
kind of odoriferous material suitable for imparting perfume to soap whether
vegetable, organic, inorganic or alone of antiseptic, chemical, or tinctorial
properties of any kind.
In carrying my invention into effect I make use of the ordinary "plodder"
with a certain addition. This mechanism as at present in use, consists essentially
of two or more cones through which the plastic soap is forced by means of a helix
revolving in the first cone and causing the soap to pass through a transverse plate-
provided with numerous small holes into a second cone in which the plastic soap
thus divided and commingled is again squeezed into a solid mass and forced through
an aperture at the apex of the cone in the form of a solid bar having the dimensions
of the tablets of soap into which it is to be divided.
In my improved machine I provide in the second cone a central spike also of
conical form with its apex terminating at the centre of the exit aperture the com-
pressed soap passing through the apertures will consequently emerge at this aper-
ture not in a solid bar but in the form of a hollow tube the size of the internal,
aperture corresponding to that of the point of the spike. The hollow bar or tube
of soap is then cut transversely into pieces of the requisite size and a little bolt or
box of any desired construction and perforated, porous, or otherwise constructed
preferably of cedar wood or other suitable material filled with one or any of the
materials aforesaid, is placed in the centre of the tube. The ends of the section
are then compressed and the whole block moulded into the requisite form, thus
forming a solid cake with a wooden or other nucleus in the centre containing the
desired perfume chemical or the like. From the central container the volatile sub-
stance gradually permeates the cake of soap. Instead of insulating the aforesaid
box at the centre of the soap cake, I may fill the hollow bar with soap of a different
colour or nature, or instead of the said box being a hollow receptacle filled with
perfume or the like I may make the same of a solid block of odoriferous or other
material such for instance as scented wood or a block of chemical in the solid state.

page_text: It is obvious also that the tube can be formed of any suitable contour inside or out
by making use of a spike or of a nozzle of equivalent contour. In this way several
concentric tubes and a solid rod of soap of different colours can be formed into one
solid bar, the small thicknesses being pressed into the larger ones preferably after
being cut up or cut into pieces afterwards transversely, and these pieces being
stamped into shape. By this means stars and other forms of one colour can be
insulated centrally in a cake of soap of another colour and such central parts will
go right through the cake.
Referring to the accompanying drawings.
Figure 1 illustrates a section of the "plodder" filled with soap under treatment.
Figure 2 illustrates a cake of soap partly in section showing one forming of
the central container also partly in section.
Figure 3 is a section of Figure 1 on the line ra, and
Figure 4 is a section of the same on the line y y.
Figure 5 is a section of the hollow bar of soap on the line z z.
The operation of the device will be obvious from these figures. The helix Z
revolved by suitable motive power forces the soap through the cone X against the
perforated friction plate A. The soap passing through the said plate in the form
of threads or strings is again compressed in the second cone Y the spike B placed
centrally in the cone Y terminates in the orifice or nozzle 1 of the cone Y, the
exuding hollow bar of soap C is shown partly in section to show the central
aperture.
Referring to Figure 2 the cake of soap C¹ is shewn partly in section, at its centre
is the container E filled with material as aforesaid, or the place of the said con-
tainer may be taken by a filling of soap of another colour, quality or properties
as already explained.
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:
1. In the manufacture of scented, medicated or the like soaps the insertion at
the centre of the tablet of a container of wood or other material filled with the
substance with which the soap is to be perfumed or imbued or of a solid block of
odoriferous wood or other material, substantially as described.
2. The process of manufacturing fancy soaps containing a core of soap of colour,
perfume or properties other than that of the rest of the cake, consisting in the
production of a hollow bar of soap and the filling thereof with soap of another
kind, substantially as described.
3. In the manufacture of fancy soap, a "plodder" having in the terminal cone
a spike such as B with its apex in or near the orifice of the said cone, substantially
as and for the purpose described.
