page_text: LETTERS PATENT to James Lamb Hancock, of Cottrill Road, Dalston Lane, in
the County of Middlesex, Engineer and Domestic Appliances Manufacturer, for
the Invention of "IMPROVEMENTS IN APPARATUS FOR MIXING, TRITURATING,
AMALGAMATING, OR OTHERWISE OPERATING UPON MEAL AND FLOUR INGRE-
DIENTS, PHARMACEUTICAL AND LIKE SUBSTANCES, IN A DRY, A PASTEY, OR A
WET STATE."
Sealed the 11th May 1880, and dated the 14th November 1879.
PROVISIONAL SPECIFICATION left by the said James Lamb Hancock at the
Office of the Commissioners of Patents on the 14th November 1879.
JAMES LAMB HANCOCK, of Cottrill Road, Dalston Lane, in the County of
"IMPROVEMENTS IN
Middlesex, Engineer and Domestic Appliances Manufacturer.
APPARATUS FOR MIXING, TRITURATING, AMALGAMATING, OR OTHERWISE OPERATING
UPON MEAL AND FLOUR INGREDIENTS, PHARMACEUTICAL AND LIKE SUBSTANCES, IN
A DRY, A PASTEY, OR A WET STATE."
The object of this Invention is the construction of apparatus in or by which a
thorough and complete mixing, triturating, amalgamating, kneading, levigating, or
other like operation can be effected upon powdery substances alone, or in combination
with moist, semi-moist bodies, or liquids.
For the purposes of my Invention I furnish a semi-cylindrical casing with a spindle
or shaft, on which I slip a series of arms, whose outer ends are flattened on the
working faces, to push the material or substance from the central part and to spread
it to the side of the casing, to effect a mixing or a kneading action upon the material,
the arms passing through and mixing the other portions of the substance in their
travel. The arms are arranged spirally or otherwise upon the spindle, that all
portions of the substance are acted upon.
The flattened ends of the arms are preferably elliptical in shape, to collect and to
mix or knead the substances under operation.

page_text: The semi cylindrical casing has in some cases a segmental outer jacket for con-
taining hot or cold water to temperate the substance within the casing, in order
that it may be effectually operated upon, it being necessary in some instances to
maintain the temperature, especially for sponge and dough fermentations and for
some pharmaceutical purposes.
The casing has a cover to prevent escape of the powdery particles or liquid
during agitation.
For egg beating, muffin paste, batter, and sponge cake making, for aërating con-
fectionery mixtures and other bodies of different gravities, I furnish a cylindrica!
casing with a grating or a meshed screen, which can be worked up and down by
hand or by an outside lever, the casing for some substances, as before mentioned,
not requiring the water jacket.

the said James Lamb Hancock in the Great Seal Patent Office on the 14th May
1880.
JAMES LAMB HANCOCK, of Cottrill Road, Dalston Lane, in the County of
Middlesex, Engineer and Domestic Appliances Manufacturer. "IMPROVEMENTS IN
APPARATUS FOR MIXING, TRITURATING, AMALGAMATING, OR OTHERWISE OPERATING
UPON MEAL AND FLOUR INGREDIENTS, PHARMACEUTICAL AND LIKE SUBSTANCES, IN
A DRY, A PASTEY, OR A WET STATE."
The object of this Invention is the construction of apparatus in or by which a
thorough and complete mixing, triturating, amalagamating, kneading, levigating, or
other like operation can be effected upon powdery substances alone or in combination
with moist, semi moist bodies or liquids.
For the purposes of my Invention I furnish a semi cylindrical casing A, as at
Figures 1 and 2 of the annexed Drawings, with a spindle or shaft B, on which are
a series of arms C, C, whose outer ends D, D, are flattened on the working faces, to
push the material or substance from the central part and to spread it to the side of
the casing A to effect a mixing or a kneading action upon the material, the arms C, C,
passing through and mixing the other portions of the substance in their travel.
The arms C, C, are arranged spirally or otherwise upon the spindle B, that all
portions of the substance are acted upon.
The flattened ends D, D, of the arms C, C, are preferably elliptical in shape, to
collect and to mix or knead the substances under operation.
The semi-cylindrical casing A has in Figure 1 a segmental outer jacket E for
containing hot or cold water to temperate the substance within the casing, in order
that it may be effectually operated upon, it being necessary in some instances to
maintain the temperature, especially for sponge and dough fermentations and for
some pharmaceutical purposes.
The casing may have a cover to prevent escape of the powdery particles or liquid
agitation.
For egg beating, muffin paste, bakers' sponge, batter, and sponge cake making, for
aerating confectionery mixtures, and other bodies of different gravities, I furnish a
cylindrical casing with a grating or a meshed screen which can be worked up and
down by hand or by an outside lever, the casing for some substances, as before
mentioned, not requiring the water jacket.
This is represented in the hand apparatus, Figure 3, within the casing A of
which a grating or meshed plunger B can be operated up and down by the
handle C.
Figures 4 and 5 shows an apparatus in which the plunger B is operated through
a lever E from the handle C, the lever being jointed at F to a link G, that the lever
E be drawn to and fro and to the right or left, that the plunger B may operate
may
upon all parts of the material within the vessel, as desired. D is the chamber for
hot or cold water heating or temperating the contents of the vessel A. Figure 6
represents an annular trough A with gear wheel H affixed, that a rotatory motion
upon rollers a, a, can be given to it by the pinions I through the action of the shaft
when turned by the handle J.
The shaft is crank at K that the rod L may actuate the lever E at the same
time as the trough is rotating. The annular trough rotates around the central stem
M, which is of a fixture, a stay N being fitted to steady its motion. If the pinion is
provided with teeth on part of its periphery only an intermettent rotatory motion
can be given to the annular trough, although the plunger continues its up and down
action, for the complete kneading or mixing of the material within it. The annular
trough may be a fixture if desired, and in this case the rock lever can be arranged

page_text: that a person can walk round the apparatus while operating the lever by the hand.
The trough may be only a segment of a circle to suit one plunger, or the trough
may be circular, within which two plungers B, B, may work from a rock beam E,
as in Figure 7.
Having now described the nature of my said Invention, and in what manner the
same is to be performed, I declare that I claim,―
The apparatus shown in Figures 1 and 2 of the Drawings, for the purposes
described.
Secondly. The plunger and vessel shown in Figure 3, also those shown in
Figures 4 and 5 of the Drawings, for the purposes described.
Thirdly. The annular trough and double plunger arrangement of mechanism, as
shown at Figure 6 of the annexed Drawings for the purposes described, also the
modification shown in Figure 7.
In witness whereof, I, the said James Lamb Hancock, have hereunto set my
hand and seal, this Fourteenth day of May, in the year of our Lord One
thousand eight hundred and eighty.
