HUVIDIONAL SI MULTIUATION.
An Apparatus for Automatically Stamping, Embossing, or
Impressing and Cutting Soap.
I, WILLIAM HESKETH LEVER of Thornton Manor Neston in the County of
Chester, Soap Manufacturer, do hereby declare the nature of this invention to be
as follows:-
The object of this invention is the construction of a continuous action automatic
machine for stamping embossing or impressing soap tablets, which enables soap
makers to turn out soap tablets more quickly and economically than can be done
by the presses at present in use.
According to this invention, I provide two concentric horizontal drums of gun
metal or other suitable material, fastened together and rotating on a sleeve of cast
iron or other suitable material held fast between the main frames of the machine.
These drums I provide with a suitable number of recesses to receive the bars of
soap to be stamped. Each of the said recesses contains one or more of the dies
for giving the required impression.
I provide further a hopper into which the soap is fed by hand or a suitable
conveyor, the lowest bar. of soap being held by a spring actuated gripping roller.
Vibrating under the said bar is a feeding plunger, actuated by means of eccentrics
keyed to the main shaft, which shaft passes through the aforesaid sleeve.
Connected to the said eccentrics or feeding plunger is an ejecting device, herein-
after called the " ejector," moving synchronously therewith. The main shaft also
bas keyed or otherwise attached thereto cranks or eccentrics for operating the
stamping portion of the apparatus.
I attach also to the crosshead carrying the dies ratchet gear for rotating the drums.
The dies attached to the moving crosshead are secured thereto by means of
bolts passing through slots in the dies, to allow the dies to drop on to the soap in
the usual way before pressure is applied.
The dies are automatically cleaned after each impression by means of revolving
brushes the one for cleaning the die in the drum being stationary, and operated by
a pitch chain from the main shaft, the dies, attached to the stamping crosshead
being cleaned by a brush, which is brought under the die, and removed therefrom
by means of gear actuated from the stamping crosshead. The soap is fed in bars
into the hopper, the lower bar being held in position just clear of the feeding
plunger, until the same has reached the full extent of its outward travel, when the
spring pressure on the gripping roller is released, and the bar of soap falls in
front of the plunger.
On the return stroke, the feeding plunger puts the bar in the recess in drums
opposite thereto,--the drums are then revolved, bringing another recess in front
of the plunger, and so on, as the drums revolve, each recess comes under the
stamping dies, which are placed directly above the vertical axis of the drums,
(the feeding and ejecting devices being horizontal) and receives the impression,
and as the drum revolves, the stamped bars are forced out of the recesses by the
ejector," and past fixed knives, which cut the stamped bars up into tablets, the
whole operation being automatic and continuous. I prefer to feed the bars into
the hopper by a suitable elevator or conveyor so as to avoid handling the soap
after forming into bars. During stamping, the drums are prevented from rotating by
means of the ejector.

An Apparatus for Automatically Stamping, Embossing, or
Impressing and Cutting Soap.
I WILLIAM HESKETH LEVER of Thornton Manor Neston in the County of
Chester, Soap Manufacturer, 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 :-
The object of this invention is the construction of a continuous action
automatic machine for stamping, embossing or impressing soap tablets, which
enables soap makers to turn out soap more quickly and economically than can be
done by the presses at present in use.
According to this invention, I provide two concentric horizontal drums of gun
metal or other suitable material, fastened together and rotating on a sleeve of cast
iron or other suitable material held fast between the main frames of the machine.
These drums provide with a suitable number of recesses to receive the bars of
soap to be stamped.
Each of the said recesses contains one or more of the dies for giving the
required impression. I provide further a hopper into which the soap is fed by
hand or a suitable conveyor. The lowest bar of soap may be held by a spring
actuated gripping roller. Vibrating under the said bar is a feeding plunger
actuated by means of eccentrics keyed to the main shaft, which shaft passes
through the aforesaid sleeve. Connected to the said eccentrics or feeding plunger
is an ejecting device hereinafter called the "ejector," moving synchronously
therewith. The main shaft also has keyed or otherwise attached thereto cranks or
eccentrics for operating the stamping portion of the apparatus. I attach also to
the crosshead carrying the dies ratchet gear for rotating the drums. The dies
attached to the moving crosshead are secured thereto by means of bolts passing
through slots in the dies, to allow the dies to drop on to the soap in the usual way
before pressure is applied. The dies are automatically cleaned after each
impression by means of revolving brushes, the one for cleaning the dies in the
drum being stationary and operated by a pitch chain from the main shaft, the dies
attached to the stamping crosshead being cleaned by a brush which is brought
under the dies and removed therefrom by means of gear actuated from the
stamping crosshead. The soap is fed in bars into the hopper, the lower bar being
held in position just clear of the feeding plunger until the same has reached the
full extent of its outward travel, when the spring pressure on the gripping roller
is released and the bar of soap falls in front of the plunger. On the return stroke
the feeding plunger pushes the bar into the recess in the drums, opposite thereto, the
drums are then revolved, bringing another recess in front of the plunger, and so on.
As the drums revolve, each recess comes under the stamping dies, which are
placed vertically above the axis of the drums (the feeding and ejecting devices
being horizontal) and receives the impression, and as the drum revolves, the
stamped bars are forced out of the recesses by the ejector, and past fixed. or
movable knives which cut the stamped bars up into tablets, the whole operation
being automatic and continuous.
I prefer to feed the bars into the hopper by means of a suitable elevator or
conveyor, so as to avoid handling the soap after forming it into bars. During
stamping the drums are prevented from rotating by means of the ejector. And in
order that my invention may be the better understood, I will proceed to explain
the same with reference to the accompanying sheets of drawings, in which
Fig. 1 represents a cross section of a soap stamping and cutting machine
constructed according to my invention.

page_text: horizontal drums fastened to each other so as to rotate together on the sleeve c,
which is secured to the frames d. These drums a and are provided with
recesses 1, 2, 3, 4, 5, 6, 7, 8, to receive the bars of soap to be stamped and cut,
each recess also contains, so fitted as to slide easily therein, one or more of the
dies e, for giving the required form and impression to the soap tablets, is the
hopper into which the bars of soap & are fed by hand or by means of a suitable
conveyor, the lowest bar of soap g, being held by the spring actuated gripping
roller h. is n feeding plunger, vibrating in a horizontal plane, and actuated by the
eccentrics k. k. and rods k¹¹, the said eccentrics being secured to the main shaft
which passes through the sleeve c. m is the ejector, connected by means of the
slotted links or rods n to the feeding plunger, and moving synchronously therewith..
The main shaft / has keyed or otherwise attached thereto, the eccentrics o. o. for
operating the stamping crosshead to which the dies 7. 7. are attached for
stamping the soap. These dies are secured to the cross head by means of bolts r,
P
passing through slots in the dies, to allow the latter to drop onto the soap, in the
usual way before pressure is applied thereto.
To the cross head p, I attach the slotted links s. s. engaging with pins t. t. in the
levers u. u., which levers are connected by a rod e, carrying pawls w. w. for
actuating the ratchets . a., which rotate the drums a and 7. The rod » is also
carried by guide blocks y moving in curved slots in the frames d. The dies are
cleaned after each impression by means of revolving brushes A. B. driven by pitch
chains or other suitable gearing from the main shaft I, the brush A for cleaning
the dies in the drun rotating in fixed bearings in the frames d, the other brush B,
for cleaning the dies attached to the cross head p being mounted on a shaft C
carried by the frame D, secured to a ring E, capable of rotation round the sleeve c
and brought into position for cleaning the dies and removed out of contact
therewith by the link F attached to the crosshead. The slotted links or rods n,
connecting the ejector m to the plunger i, are guided by rollers K, working in
guides L L, secured to the sleeve c.
The ejector m, when in the position shown at Fig. 1, holding the drums a. b. from
rotating.
The action of the apparatus is as follows:-
The bars of soapy are fed by hand or by means of a suitable conveyor into the
hopper the lower bar g¹ being held by the gripping roller till the feeding
plunger i has reached the limit of its movement away from the drums a. b., when
the pressure on the said roller is released and the bar y' drops in front of the
feeding plunger. On the return stroke of the plunger i, the bar of soap g' is
pushed into the recess 1 opposite the plunger i and when the dies attached to the
cross hend p are lifted clear of the drums, the brush B is brought under the same
by the link F, and cleans them, the lower end of the slotted links & engaging with
the pins t the drums a. bare rotated, one eighth of a revolution by the pawls w.
The next revolution of the shaft causes another bar of soap to be placed in
the recess 2, and again rotates the drums one eighth of a revolution.
The next revolution of the shaft carries the bar of soap gl in the recess 1
under the stamping dies attached to the cross head p, and receives the impression.
The impressed soap is then carried forward by the revolution of the drums a. b
till it comes opposite the ejector m, which at the same time as the plunger i is
feeding the soap into the recess 5, pushes the bar g' out of the recess 1, past the
knives H, cutting the stamped bar into tablets, the ejector meanwhile holding the
drums a. b. from rotating, while the dies attached to the cross head p. impress
the bar in recess 3, which is now below the said dies. After each impression, the
dies are cleaned by the brushes A and B as before described.
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
(1). In an apparatus for automatically stamping, embossing, or impressing soap,

page_text: the combination of a rotating drum or drums having recesses therein, containing
dies with a means of automatically placing soaped to be stamped in the recesses
and ejecting the soap therefrom after stamping substantially as hereinbefore
described.
(2). In an apparatus for automatically stamping, embossing, or impressing soap
the combination of an ejecting device with a means of cutting the stamped soap
into tablets substantially as hereinbefore described.
(3). In an apparatus for automatically stamping embossing or impressing soap,
holding the cylinder in position for stamping by the ejector, substantially as
hereinbefore described.
(4). The improved apparatus for automatically stamping, embossing or im-
pressing soap, substantially as herein before described and shown and operating in
the manner specified.
