Improvements in or appertaining to the Manufacture or Shaping
of Soap.
I, RICHARD CLARKSON SCOTT of Burlington House, Litherland Park, in the
County of Lancaster, Manufacturer, do hereby declare the nature of this invention
to be as follows :-
Soap being a very slippery article, especially when being used, is apt to slip out
of the fingers. This invention is designed to prevent this and thus avoid a great
deal of annoyance.
I form my bars of soap with two or more sides corrugated with deep corruga-
tions, or it may be with deep indentations of a semi-spherical or other shape so that
the fingers can firmly grasp the indentations. The bars can be formed by rolling,
by passing them between two rolls set a little distance apart and having peripheries
somewhat like cogwheels but shaped with the corrugations or other projections
requisite to form the indentations. The sides through which the soap passes can
be smooth and flat or hollowed out so as to give the bar of soap a flat or a rounded
form, or in place of these two forms the sides can be convex and thus a cavity is
formed on the top and bottom of the soap making the latter appear with a larger
edge surface for a given weight of soap than it would otherwise have.
the corrugations on the wheels any name or trade mark can be moulded and if
desired distances apart at say three or four inches deeper cogs on the wheels can be
formed opposite each other so as to nearly cut the bar of soap in two. By this
means the bar can be broken by hand into pieces of half pound, three quarters of
a pound, one pound, or other quantity as required, the distances between the rolls
being so regulated that the weight of soap will remain between each two set of
opposite deep indentations.

COMPLETE SPECIFICATION.
Improvements in or appertaining to the Manufacture or Shaping
of Soap.
I, RICHARD CLARKSON SCOTT, of Burlington House, Litherland Park, in the
County of Lancaster, Manufacturer, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
Soap, being a very slippery article, especially when being used in water, is
apt to slip out of the fingers; this invention is designed to prevent this and
thus avoid much annoyance, and also to arrange the soap so that it shall drain dry
quickly when out of the water by being laid on the corrugated sides, and also
shall have little tendency to form the disagreeable jelly which soap does form
when left standing on a flat surface, owing to the collection of water around it,
and which, forming a jelly, causes a great waste in the soap.
I form my bars of soap with two or more sides corrugated with deep corruga-
tions (or it may be with deep indentations of a semi-spherical or other shape)

page_text: so that the fingers can firmly grasp the indentations. The indentations, where
used, can meet in the centre and thus form a hole right through the block. The
advantage of this is that the water can drain away from the hole or indentation
instead of standing in it when the soap is not in use. If the soap be left
standing on the apices of the corrugations, the water quickly drains away, and
has little or
no tendency to form the disagreeable jelly which soap does form
when left standing on a flat surface, owing to the collection of water round it,
to the great waste of the soap.
I prefer corrugations or deep grooves to simple semi-spherical or other
The corrugations or grooves can be horizontal, vertical, oblique or
indentations.
curved.
In carrying out my invention, I prefer to use a modification of the ordinary
stamping machine, the only difference being that it is larger and stronger so as
to take in a bar instead of a tablet, and, of course, the mould is formed with the
requisite corrugations.
Besides this method of making the corrugations, however, the soap can be cut
with corrugated knives from the lump, from the slab, or from the bar, or, with
some very tough soaps, bars or slabs can be corrugated by rolling between
corrugated rollers, but neither of these plans is as good as the stamping machine.
If the bottoms of the corrugations are somewhat rounded longitudinally, or are
rather higher in the centre of the side than at the corners, and the piece of soap
be laid down corrugations downward-the water will run off it much more
quickly and completely than it will do off a flat bar.
Referring to the drawings:
Figure 1 is a bar of soap having vertical corrugations on its sides and stamp
on the top and bottom at intervals, separated by a deep wedge like nick corre-
sponding to a similar one in the bottom, and to nicks in the sides.
These are
arranged at definite distances in the mould, so that if, for instance, a three pound
bar and a two and a quarter pound bar were both stamped in a mould having
six divisions, one would give eight ounce cakes when cut at these points,
the other, six ounce cakes.
Figure 2 is a bar with horizontal indentations on each side and vertical
corrugations at the top and bottom at intervals as before.
Figure 3 is a bar with holes right through from side to side, preferably doubly
ccnical, somewhat the shape of an hour glass with thick waist, the holes being
about inch to 1 inch diameter to allow the fingers entering.
Figure 4 is a simple uniformly corrugated bar formed by the slab of soap being
cut into bars by means of corrugated knives.
Figure 5 is a piece cut from an ordinary bar of soap by means of a corrugated
knife reciprocating vertically downward, and thus forming corrugated ends.
For this purpose, I have designed a machine that will cut off pieces from bars of a
given weight and sectional area, so as to form pieces of exactly pound, pound,
pound, efestera. This machine will also cut off pieces of given weight from the
simple corrugated bars shown in Figure 4, but, as a rule, it is needless to have
more than two opposite surfaces corrugated. I give these four forms of bar as
instances, but the varieties of bar made in accordance with my invention are
endless.
In conclusion, I am well aware that bars of soap, made in the form of two
tablets separated by a deep nick all round so that they can be easily cut in two,
are well known, and I make no claim for this.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
A bar or tablet of soap formed with corrugations, grooves, indentations, pro-
jections or the like, within or between which the fingers may lie or into which
they may partly enter and thus grasp the soap firmly and securely, and by means

page_text: of which the water may quickly drain off when the soap is placed with the
corrugations downwards on a flat surface, substantially as described.
