An Improved Apparatus for Mixing Flour, Colours, Seeds, and the like.

An Improved Apparatus for Mixing Flour, Colours, Seeds,
and the like.
I, HENRY HAMMOND HILLMAN, of 75, Nottingham Road, in the County Borough
of Derby, Merchant, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to minimise the difficulty experienced in
thoroughly incorporating one substance with another in mixing flours of various
kinds, colours and the like, it is also applicable to mixing granular substances
seeds and the like, although it will be more particularly referred to hereinafter
as applied to flour mixing.
In carrying out my invention I employ two or more hoppers converging
downwards on to a revolving cone having flutes or corrugations therein or
thereon either spirally arranged or in straight lines, and a flange running round
the base; this cone is mounted loosely on a feather key or keys upon a central
shaft and the whole is provided with any suitable outer casing.
The cone shaft is mounted in suitable bearings in the top and bottom of the
outer casing or to prevent the shaft revolving in the flour or the like it may
be surrounded with and revolve inside a hollow cylinder suspended from the
top of the casing the cone is capable of vertical adjustment on the said shaft
according as the lower mouths of the hoppers are desired closed when the
apparatus is at rest, or to regulate the feed of flour or the like over the flange
of the base of the cone; to effect this vertical adjustment I employ a fork
pivotted to the outer casing or in other suitable position the forked extremity
or extremities engaging underneath or being connected in any suitable manner
with a collar loosely mounted on the cone the outer extremity of the fork being
balanced if necessary and arranged to be stopped in any desired position vertically:
this device may be placed below the apparatus if desired and worked with a
treadle.
In the case of flours and other substances they would pass from the mixer
by a suitable shute or conduit into a chamber or receptacle whence they could
be drawn into the spout of a sifter for cleaning purposes.
The cone shaft may be driven from any suitable source of power preferably
from above by means of fast and loose pulleys, bevil gear or the like, or, in the
case of small apparatuses it may be driven by hand.
It will be seen that the flour and the like is scattered in a continuous shower
upon the inside of the outer casing which is afterwards preferably tapered to
the shute or conduit above mentioned.
There may be also regulating or closing slides in the hoppers if desired.

1, HENRY HAMMOND HILLMAN, of 6, Darwin Terrace, in the County Borough
of Derby, and formerly of 75, Nottingham Road, in the County Borough of
Derby aforesaid, Merchant, 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 to minimise the difficulty experienced in
thoroughly incorporating one substance with another in mixing flours of various
kinds, colours and the like, it is also applicable for mixing granular substances,
seeds and the like, although it will be more particularly referred to hereinafter
as applied to flour mixing.
In describing my invention reference will be had to the accompanying sheet
of drawings upon which Figure 1 is a plan of my improved apparatus; and
Figure 2 is a vertical section of same on line a, of Figure 1.
In carrying out my invention I employ two or more hoppers A converging
or leading downwards on to a revolving cone or disc B having flutes or corru-
gations therein or thereon if desired either spirally arranged or in straight lines;
this cone or disc is mounted on a feather key or keys or by other suitable means
upon a central shaft C and the whole is provided with any suitable outer
casing and framing E.
The cone or disc shaft is mounted in suitable bearings F carried pon suit-
able bearers or framing E' or to prevent the shaft revolving in the flour or the
like it may be surrounded with and revolve inside a hollow cylinder suspended
from the top of the casing, upon the drawings the inner faces A of the
hoppers would constitute such a protecting casing: the cone or disc shaft C is
capable of vertical adjustment according as the lower mouths of the hoppers are
desired closed when the apparatus is at rest, or to regulate the feed of Hour or
the like over the cone or dise; to effect this vertical adjustment I may employ
a fork G pivotted to the framing or in other suitable position the forked extremity
or extremities engaging underneath or being connected in any suitable manner
with a collar H loosely mounted on the cone or disc shaft the outer extremity
of the fork being balanced if necessary and arranged to be stopped in any
desired position vertically such as by means of a spring catch J and rack K;
this device is shewn by dotted lines upon Figure 2, and, I may without departing
from the spirit of my invention substitute for this arrangement the device shewn
in firm lines on Figure 2 consisting of a handwheel L with threaded spindle M
passing loosely into the sleeve N the lower end of which is fixed to the disc
spindle and the upper end of which has a pin passing through it engaging an
annular recess in the threaded spindle, so that as the disc revolves the handwheel
may remain stationary.
In the case of flours and other substances they would pass from the mixer by
a suitable shute or conduit O into a chamber or receptacle whence they could
be drawn into the spout of a sifter for cleaning purposes.
The cone or disc shaft may be driven from any suitable source of power by
means of fast and loose pulleys, bevil gear l' or the like, and in the case of a
small apparatus it may be driven by hand (as shewn upon the drawings).
It will be seen that the flour and the like is scattered in a continuous shower
upon the inside of the outer casing which is afterwards preferably tapered to
the shute or conduit as shewn.

page_text: There may be also regulating or closing slides in the hoppers if desired j
and without departing from the spirit of my invention I may make the hoppers
taper or parallel and if found desirable dispense with the flutes corrugations
or the like on the disc or cone; the upper part of the cone may be made to cut
into the hoppers as shewn at B' and act as an agitator to prevent the flour or
the like clogging or packing.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
The improved apparatus or device for mixing flour, colour, seeds and the
like, having a vertically adjustable revolving disc or cone mounted or suspended
in suitable bearings inside a casing and framing in combination with vertical
or inclined hoppers and means for driving said disc or cone substantially as
described and illustrated.
