PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Cutting Soap.
We, CHARLES WHEEN, of Creek Road, Deptford, in the County of Kent,
Soap Maker, and THOMAS BROWN, of 62 Wotton Road, Deptford aforesaid,
Foreman, do hereby declare the nature of this invention to be as follows:-
1
According to this invention a slab of soap is cut into small pieces by being first
passed through one set of parallel wires and afterwards through a second set in a
direction at right angles to the first.
The planes in which the two sets of parallel wires are situated are at right
angles to each other and the wires rise vertically from a table upon which are two
pushers. The slab of soap is placed on the table and is thrust by the first pusher
through the first set of wires and is so cut into bars. The second pusher then
advances and thrusts the bars sideways through the second set of wires cutting
them into cubes or other rectangular pieces of the desired size.
Meanwhile the first pusher has retired leaving a space on the table between it
and the wires upon which a second slab is placed ready for the operation to be
repeated.
-
The pushers work in guides and are operated from cams on the main shaft of
the machine the first pusher is connected by a rod to the long arm of a T shaped
lever the shorter arms of which are pivotted to the ends of two rods whose other
ends bear against a pair of cam surfaces on the main shaft. The other pusher has
fixed to it a rod carrying two blocks or surfaces also bearing against a pair of
cans on the main shaft.

Improvements in Apparatus for Cutting Soap.
We, CHARLES WHEEN, of Creek Road, Deptford, in the County of Kent,
Soap Maker, and THOMAS BROWN, of 62 Wotton Road, Deptford, aforesaid,
Foreman, 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:―
According to this invention a slab of soap is cut into small pieces by being first
passed through one set of parallel wires and afterwards through a second set in a
direction at right angles to the first.
The plaucs in which the two sets of parallel wires are situated are at right
angles to each other and the wires rise vertically from a table upon which are two
pushers. The slab of soap is placed upon the table and is thrust by the first
pusher through the first set of wires and is so cut into bars. The second pusher then
advances and thrusts the bars sideways through the second set of wires cutting
them into cubes or other rectangular pieces of the desired size.
Meanwhile the first pusher has retired leaving a space on the table between it
and the wires upon which a second slab is placed ready for the operation to be
repeated.
:
The pushers work in guides and are operated from cams on the main shaft of
the machine the first pusher is connected by a rod to the long arm of a T shaped
lever the shorter arms of which are pivotted to the ends of two rods whose other
ends bear against a pair of cam surfaces on the main shaft. The other pusher has

DESCRIPTION OF THE DRAWINGS.
Figure 1 is a front elevation of the machine, Figure 2 is a section on the
line looking to the right, Figure 3 a plan, Figure 4 a left hand side elevation
and Figure 5 a section on the line - looking to the left Figures 1 and 3.
a is a table on which the slab of soap is placed, at one side of it is a vertical
wall which serves as a guide. are two frames each supporting a number of
parallel vertical wires. c and d are two pushers supported on rollers c and d'.'
e is the main shaft of the machine to which motion is given by a belt working on
the pulley ee is a toothed pinion on the shaft e gearing with the toothed
wheel on the second motion shaft f. gg and hh are four cams or wipers on
the shaft f
The cams galternately come against the upper ends of the slides j
which are connected by the rods j' to the ends of the arms of the lever / fixed on
the shaft. This shaft has a vertical arm fixed to it to whose end is pivotted
the connecting rod the other end of which is pivotted at to the stem of the
pusher c. Thus as the shaft revolves the shaft ¹is rocked and the pusher c is
caused to reciprocate on the table a.
The cams alternately come against inclined projections mm' fixed to the
frame of the pusher d so that as the shaft revolves the pusher d is caused to
reciprocate on the table a.
Assuming the cycle to commence when the pusher c is fully back in the position
indicated by dotted lines in Figure 3 and a slab of soap has been placed on the
table a between the pusher c and the wires in the frame the action of the machine
is as follows: The pusher c advances towards the wires forcing the soap through
them thus cutting it into bars the motion continuing until the wires enter the
notches in the face of the pusher. The pusher then at once retires and remains
stationary for some time in the position shown in dotted lines in Figure 3 so that
the workman can place another slab of soap on the table a and against the wall a'.
Meanwhile the pusher dis advancing carrying the bars of soap before it through
the wires in the frame cutting them into cubes. When the wires benter the
notches in the face of the pusher d the latter stops and retires and the cycle is
completed.
In some cases it is desirable to cut the slabs to the proper size upon the machine
itself instead of previously. Figure 6 is a rear elevation and Figure 7 a right
hand end view of the above described machine to which an arrangement for doing
this has been added. n is an arm to which two guide rods n' n' are fixed. These
rods are connected by a cross bar o and work in guides pp-y is a single wire
having its ends fixed to the arm n and cross bar o respectively. r is an arm fixed
to the shaft k¹ which is prolonged for this purpose. s is a connecting rod pivotted
to the upper end of the arm and to the arm n. The wire therefore works to
and fro with the pusher c. As shown in Figure 7 the table a is made somewhat
broader than before. When the pusher c is fully drawn back and is pausing in
that position as above described the workman pushes a large slab of soap along
the table a in the direction of the arrow Figure 7 until it is arrested by the
wall a. The front portion of this slab has been cut off by the previous passage of
the wire and when the pusher again advances this severed portion only is
carried with it whilst the wire y which moves simultaneously with the pusher cuts
off another piece and so on.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. In machines in which slabs of soap are pushed in succession through two sets
of wires at right angles to each other moving the pushers positively in each
direction hy cums on a sincrlo aum If

page_text: 2. Operating one of the pushers directly and the other through a rocking shaft
substantially as described.
3. Apparatus for cutting soap substantially as described and shown in the
drawings.
