GEORGE HENRY WILDSMITH of Calder Grove, Dewsbury in the County of York
Commercial Traveller do hereby declare the nature of this invention to be as
follows:-
The object of my Invention is to produce names, letters, figures, initials, trade-
marks and other devices in or through soaps, in such a manner that they are more
permanent and durable than those now produced by recessing, embossing, stamping,
or other methods of marking now in use.
The great disadvantage of the present methods of marking soaps is, that such marks
are obliterated after the soap has been in use a short time, owing to the surface soap
containing or forming these marks being washed away.
My improved method of marking soaps consists essentially of two operations ;
namely, producing suitably shaped spaces which pass through the full thickness or
length of the soap, and afterwards filling these spaces with soap of another colour or
shade. The figures, marks, etc. produced by my method, therefore, will last as long
as the bar or tablet of which they form a part.
In order to produce these marks I proceed as follows. The block, bar, tablet or
other piece of soap to be marked, is placed or held in front of a moveable die or type
carrier, which carrier has attached thereto long type, (preferably of metal) of the
letters or marks to be produced in the soap tablet or bar. A forward motion of the
type carrier forces the type through from end to end of the soap bar or tablet. After
the type is withdrawn, the fluid marking soap flows into and fills the interstices
produced by the die or type. The run of the liquid soap into the interstices may be
caused by pressure.
Where the size or thickness of the type is considerable, or the thickness of the bar
or tablet of soap small, the fluid marking soap may be simply poured into the openings
fter the type is withdrawn. I find it however better to have some pressure or suction

page_text: for forcing in the marking soap, and this enables me to insert the letters, marks, etc.,
through a greater thickness of soap than when it is merely poured into the openings.
Such long blocks or bars of soap are then readily cut into tablets, which may if desired
be also stamped or blocked as at present.
As another mode or method of producing these marks, I propose to mould the
names, marks, etc. separately in the first place of the desired colour or shade of
marking soap, and afterwards form the blocks, bars, or tablets, by pouring the for
soap
making the same, whilst in a fluid state round the moulded letters or marks etc.

I GEORGE HENRY WILDSMITH of Calder Grove Dewsbury in the County of York,
Commercial Traveller do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
n and by the following statement :-
The object of my Invention is to produce names, letters, figures, initials, trade
marks, and other devices, in or through soaps; in such a manner that, they are more
permanent and durable than those now produced by recessing, embossing, stamping, or
other methods of marking now in use.
The great disadvantage of the present methods of marking soaps is, that such marks
are obliterated after the soap has been in use a short time, owing to the surface soap
containing or forming these marks being washed away.
My improved method of marking soaps consists essentially of two operations,
namely producing suitably shaped spaces which pass through the full thickness or
length of the soap, and afterwards filling these spaces with soap of another colour or
shade. The figures, marks, etc. produced by my method therefore, will last as long as
the bar or tablet of which they form a part.
In order to produce these marks I proceed as follows. The block, bar, tablet, or
other piece of soap to be marked is placed or held in front of a moveable die or type

page_text: carrier, which carrier has attached thereto long type, (preferably of inetal,) of the
letter or marks to be produced in the soap tablet or bar. A forward motion of the
type carrier forces the type through from end to end of the soap tablet, or bar. After
the type is withdrawn, the fluid marking soap flows into and fills the interstices
produced by the die or type. The run of the liquid soap into the interstices may be
caused by pressure.
Where the size or thickness of the type is considerable, or the thickness of the bar
or tablet of soap small; the fluid marking soap may be simply poured into the openings
after the type is withdrawn. I find it however better to have some pressure or suction
for forcing in the marking soap, and this enables me to insert the letters, marks, etc.,
through a greater thickness of soap than when it is merely poured into the openings.
Such long blocks or bars of soap are then readily cut into tablets, which may if
desired be also stamped or blocked as at present..
As another mode or method of producing these marks 1 propose to mould the
names marks etc. separately in the first place, of the desired colour or shade of marking
soap and afterwards form the blocks, bars or tablets, by pouring the soap for making
the same, whilst in a fluid state round the moulded letters or marks, etc.
And in order that my Invention may be more completely understood, reference is
given to the accompanying drawing and to the letters and marks thereon. The drawing
represents a cross section of a machine for producing the aforesaid perforations or
spaces through blocks or bars of soap, and for filling in such perforations with soap of
another colour or shade.
The apparatus as shewn consists of a central vessel a, containing a supply of the
marking soap in a suitably fluid state. The vessel a is contained within a second
vessel b, the space between the two forming a hot or warm water bath, for the purpose
of keeping the colouring or marking soap in a suitable state of fluidity. As shewn,
the water bath is heated by means of a gas stove and hot water coil d, which is joined
to the warm water bath ate and f. The vessel a is shewn provided with a piston at g,
which being weighted or otherwise forced down, serves to place the more or less fluid
marking soap under pressure. Where the apparatus is of a large size, the piston is
provided with a rack and wheel arrangement, or other mechanism for lifting the same;
and the piston may be made hollow as shewn at h, for the introduction of the marking
soap.
In front of the cylinder a is provided the outlet i, which is opened and closed at
suitable times by means of a reciprocating slide j, driven by a cain and lever arrange-
ment from the main shaft k. Directly beneath the opening, which is opened and
closed at suitable times, is provided a moveable die or type; which moves vertically
up and down, being carried by the cross-head m, sliding over the guides n, and
actuated through a connecting rod from the crank o. The die or type passes through
a guide or suitable holes in the table p, on which rests the block of soap.
The table p
is carried on springs, which are automatically depressed by means of the cams,
acting at suitable times on the steel block or cross piece carried by the rods t from the
table p. By means of the pusher u shewn in section, the block of soap to be perforated
is pushed on the table p, whilst the latter is depressed. Immediately the table p is
released, the springs force up the same, pressing the top of the soap tightly against
the underside of the reciprocating slide j, or rather against the perforated plate; and
the moveable type or die then rises and penetrates the soap, the type or die
continuing to rise till it enters the corresponding perforations in the plate e.
same time the reciprocating slide has opened the outlet i, so that on the descent of
the type or die , the coloring or marking soap is drawn or forced into the mould or
openings formed in the block or bar of soap.
At the
Immediately the descending type or die leaves the bar of soap, or just before, the
reciprocating slide closes the outlet : and the pusher u, which during this time has
been gradually withdrawn, now advances with a fresh block of soap, placed in front of
it by the attendant, which displaces the last block of soap just marked, by pushing the
same forward.
Adjustable side guides we are provided, between which the blocks of soap are placed.

page_text: Instead of opening and closing the outlet i by means of the reciprocating slide j, I
propose in some cases to employ a conical or other form of lifi valve, which is either
weighted or pressed down against its seat by means of springs. The underside of the
valve is formed flush with the underside of the seat or casting against which the top
of the block or bar of soap is pressed. The valve is lifted by the last fraction of the
stroke of the type or die 1, and is held open by means of a catch during the whole of
the return or descent of the type or die ; such catch being released immediately
before the down stroke of the type or die is completed. The pressure with which the
valve is held down, is that necessary to leave a clean cut or opening at the top of the
block or bar for the entrance of the coloring or marking soap.
The type or die is preferably, though not necessarily formed of small rods or
needles, circular or square in section, the perforations in the table p or plate e being
correspondingly formed of round or square holes, (i.e. the mark itself is composed of
round or square dots suitably arranged to form letters or other devices. The upper
ends of such rods are formed conical or pointed.
Instead of having a weighted piston, hydraulic or other pressure may be readily
arranged to act on the surface of the coloring or marking soap.
It will be readily understood that I do not limit myself to the precise arrangements
and all the details shown in the drawings and described above, as these may be varied
or altered without altering the nature of my said Invention.
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° The marking of soap by forming suitably shaped spaces through the full thickness
of the soap, and afterwards filling up these spaces with soap of another colour or
shade, substantially as herein set forth.
2° Apparatus for marking soap in the manner described in Claim 1°, consisting of,
a moveable die or type for perforating blocks, bars, or tablets of soap, a vessel for
holding the coloring or marking soap in a suitably fluid state, and mechanism for
actuating the die, and for opening and shutting off communication with the vessel
containing the marking soap, substantially as herein set forth.
3 The arrangement, construction, and application of apparatus for marking soap,
substantially as and for purposes herein set forth, and as illustrated in the accom-
panying drawing.
