page_text: LETTERS PATENT to Benjamin Goddard, of Stockport, in the County
of Chester, Druggist, and William Finley, also of Stockport, in
the said County, Cotton Spinner, for the Invention of "IMPROVED
MACHINERY FOR PILL MASS MIXING AND PILL MAKING, MIXING PLASTIC
SUBSTANCES, MAKING PLASTER ROLLS, AND FOR OTHER SIMILAR OR ANALOGOUS,
PURPOSES."
Scaled the 24th May 1870, and dated the 25th November 1869.
PROVISIONAL SPECIFICATION left by the said Benjamin Goddard
and William Finley at the Office of the Commissioners of Patents,
with their Petition, on the 25th November 1869.
We, BENJAMIN GODDARD, of Stockport, in the County of Chester,
Druggist, and WILLIAM FINLEY, also of Stockport, in the said County,
Cotton Spinner, do hereby declare the nature of the said Invention for
"IMPROVED MACHINERY FOR PILL MASS MIXING AND PILL MAKING, MIXING
PLASTIC SUBSTANCES, MAKING PLASTER ROLLS, AND FOR OTHER SIMILAR OR ANALO-
GOUS PURPOSES," to be as follows:-
This Invention has for its object the production of improved machinery
or machines for mixing and making pills, mixing plastic substances

page_text: and making the same into rolls and balls. Upon a suitable base we
mount a frame, in or to which we fit a mass mixer, a moveable mass
table or trough, adjusting rollers for rolling the mass into slabs of the
required thickness, cutters and gauge for cutting the slabs into strings,
the sizes of which can be regulated by the gauge as required, and
vertical grooved plates for making the strings into pills or balls. The
rollers, cutters, and grooved plates are so geared and connected that they
can be actuated simultaneously or separately.
The improved mixer consists of a hollow cylinder with either open
or closed. ends, which may be made in sections to open, or in one piece
with a lateral or side opening for charging it with the matter to be
mixed therein. Through the axis of this cylinder we run a shaft having
a piston at one end and a disc, toothed wheel, and knob at the other,
carrying a number of radially fixed knives, spikes, or beaters, along the
centre or space between the piston and disc above mentioned, which
latter are turned so as to fit accurately the interior of the oylinder
which is bored to receive them. In this cylinder we next insert through
perforations along the side a number of blades, spikes, or fingers fixed
to a finger bar for inserting and removing them bodily when required.
The blades on the shaft are so managed that they pass between the
blades on the finger bar, which are made of sufficient length to extend
across the interior of the cylinder on one side to the shaft, and as the
latter is turned the mass is thus thoroughly mixed, when on removing
the finger bar the said shaft can be withdrawn by the knob, and draws
out the mass with it by the piston at the opposite end. For giving
motion to the shaft when turned by hand a pinion is fitted to the frame
so as to gear with the toothed wheel before described, and this pinion is
turned by a handle. The mass table upon which the mixed mass
is placed is a slab or plate with sides, one end of which is placed close
to the rollers so that when the latter are turned backwards and forwards
they draw the mass through and roll it into slabs of the required thick-
ness. Over this table we fit a rotating perforated hollow cylinder con-
taining dust for dusting the mass. These rollers are placed one over
the other and geared at the ends, so that their distances apart can be
adjusted for rolling slabs of different thicknesses. The upper roller is
fitted with a ratchet or notched wheel and lever pawl for working the
rollers when the cutter and pill making plates are in action. In order to
regulate the size of the pills we use changing notch wheels having

page_text: different numbers of teeth. The cutter is a long knife which is placed
in front of the rollers, and works up and down through a slot in the
bottom of a trough containing dust for dusting its sides. At right
angles to the front side of the cutter knife we fit a scraper, which is geared
so as to move simultaneously with the cutter and insure the separation
and dropping of the string cut off from the slab at each cut. Imme-
diately under the cutters also in front of the machine, we fit the grooved
plates into the space between which the string separated from the slab
at each cut fall; one of these plates is a fixture, and the other moveable
by means of a compound lever, which gives thereto a reciprocating
vertical motion, and thus the strings are cut and rolled into pills or balls
and fall out underneath into a suitable receiver, and are coated with dust
ready for being put up for sale and use.
When the machine is required to make plastic rolls instead of pills
or balls the slab making table and rollers are removed, and a trough
with a moveable end and grooved rollers substituted therefor. The
plastic mass is then placed in the trough, the duster before mentioned
being supplied with water instead of dust, and on turning the rollers
the mass is wetted and forced against them by the moveable end of the
trough which is drawn towards them and carries the mass with it.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
. filed by the said Benjamin Goddard and William Finley in the
Great Seal Patent Office on the 25th May 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, BENJAMIN
GODDARD, of Stockport, in the County of Chester, Druggist, and
WILLIAM FINLEY, also of Stockport, in the said County, Cotton Spinner,.
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fifth day of November, in
the year of our Lord One thousand eight hundred and sixty-nine, in
the thirty-third year of Her reign did, for Herself, Her heirs and
successors, give and grant unto us, the said Benjamin Goddard and
William Finley, Her special licence that we, the said Benjamin Goddard
and William Finley, our executors, administrators, and assigns, or such
others as we, the said Benjamin Goddard and William Finley; our

page_text: executors, administrators, and assigns, should at any time agree with,
and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exer-
cise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "In-
PROVED MACHINERY FOR PILL MASS MIXING AND PILL MAKING, MIXING PLASTIC
SUBSTANCES, MAKING PLASTER ROLLS, AND FOR OTHER SIMILAR OR ANALOGOUS
PURPOSES," upon the condition (amongst others) that we, the said
Benjamin Goddard and William Finley, our executors or adminis
'trators, by an instrument in writing under our, or their, or one of
their hands and seals, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to
be perfornied, and cause the same to be filed in the Great Seal Patent
'Office within six calendar months next and immediately after the date
of the said Letters Patent.
NOW KNOW YE, that we, the said Benjamin Goddard and William
Finley, do hereby declare the nature of our said 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 the production of improved machinery
or machines for mixing and making pills, mixing plastic substances, and
making the same into rolls and balls. Upon a suitable base we mount
a frame, in or to which we fit a mass mixer, a moveable mass table, slab,
or trough, adjusting rollers for rolling and flattening the mass to the
required thickness, cutters and gauge for cutting the flattened mass into
strings, the sizes of which can be regulated by the gauge as required,
and vertical grooved plates for making the strings into pills or balls.
The rollers, cutters, and grooved plates are so geared and connected that
they can be actuated simultaneously or separately.
The improved mixer consists of a hollow cylinder or cone, with
either open or closed ends, and made in sections to open, or in one
piece with a lateral or side opening for charging it with the matter
to be mixed therein. Through the axis of this cylinder or conc
we run a shaft having a piston at one end and a disc, toothed wheel,
and knob at the other, and between the piston and disc above.
mentioned a number of radially fixed knives, spikes, or beaters. The
end piston and disc are turned so as to fit accurately the interior of the

page_text: cylinder, which is bored to receive them. In this cylinder we next
insert through perforations along the side a number of blades, spikes,
or fingers fixed to a finger bar for inserting and removing them bodily
when required. The blades on the shaft are so arranged that they pass
between the blades on the finger bar, which are made of sufficient length
to extend across the interior of the cylinder on one side of the shaft,
and as the latter is turned the mass is thus thoroughly mixed, when on
removing the finger bar the said shaft can be withdrawn by the knob,
and draws out the mass with it by the piston at the opposite end. For
giving motion to the shaft when turned by hand a pinion is fitted to
the frame so as to gear with the toothed wheel before described, and this
pinion is turned by a handle. The mass table upon which the mixed
mass is placed is a slab or plate with sides, one end of which is placed
close to the rollers, so that when the latter are turned backwards
and forwards they draw the mass through and roll it to the required
thickness. Over this table we fit a rotating perforated hollow cylinder.
containing dust for dusting the mass. The rollers are placed one over
the other and geared at the ends, so that their distances apart can bo
adjusted for rolling the mixed mass into cakes or slabs of different
thicknesses. The upper roller is fitted with a ratchet or notched wheel
and lever pawl for working the rollers when the cutter and pill making
plates are in action.
In order to regulate the size of the pills we use changing notch whicels
having different numbers of teeth. The cutter is a long knife, which is
placed in front of the rollers and works up and down through a slot in
the bottom of a trough containing dust for dusting its sides. At right
angles to the front side of the cutter knife we fit a scraper, which is
geared so as to move simultaneously with the cutter and insure the
separation and dropping of the string cut off from the cake or slab at
each cut. Immediately under the cutters and also in front of the machine
we fit the grooved plates into the space between which the strings
separated from the slab at each cut fall; one of these plates is a fixture
and the other moveable by means of a compound lever, which gives
thereto a reciprocating vertical motion, and thus the strings are cut and
rolled into pills or balls and fall out underneath into a suitable
receiver and are coated with dust ready for being put up for sale
and use.

page_text: When the machine is required to make plastic rolls instead of pills
or balls the cake or slab making table and rollers are removed, and a
trough with a moveable end and grooved rollers substituted therefor.
The plastic mass is then placed in the trough, the duster before mentioned
being supplied with water instead of dust, and on turning the.
rollers the mass is wetted and forced against them by the moveable
end of the trough, which is drawn towards them and carries the mass
with it.

page_text: in the same way by making the blades on one side screw to the right
and those on the opposite side screw to the left. For varying the thick-
ness of the cakes the journals of the shaft of the roller c are provided
with changing brasses, and the teeth of the gearing wheels are made of
an extra depth. After the mass has been prepared in the mixer and
rolled to the required thickness the pill making operation is performed
by working the levers j and 1, the latter having been adjusted by the
screw m to regulate the size of the string and consequently the size of
the globes or balls, the plates & and being provided with changing faces
in which the grooves are of different sizes. By removing the screw in
the leverj it can be raised clear of the front and a second slab supported
by the connecting rod be attached in front so that the mass cake
can then be worked backwards and forwards between the rollers from
the front to the back slab or table, and vice versa, till thoroughly
kneaded.
In witness whereof, I, the said Benjamin Goddard, on behalf of
myself and the said William Finley, have hereunto set my hand
and seal, this Twenty-fourth day of May, in the year of our Lord
One thousand cight hundred and seventy.
