An Improved Apparatus for Rapidly Sifting, Mixing, and Blending
Flour, Meal, Powders, Grain, Seeds and the like.
We, GEORGE GARNISH and JOHN ROCK LEMON, both Millwrights and Engineers,
of Pilton, Barnstaple, Devon, and JOSEPH ABELL ELLACOTT, Commercial Traveller,
of the Hermitage, Exwick, in the County of Devon, do hereby declare the nature
of this invention to be as follows:-
-
This invention has for its object an apparatus with an improved and novel
method, for rapidly seiving, or sifting, and in one operation thoroughly mixing
or blending, two or more kinds of flour, powders, seeds, or any like or similar
articles or material, by means of two or more seives of different mesh of increased
fineness, placed over each other, and attached to two or more vibrateing frames,
hung or held in position by two or more specially designed vibrateing spindles
hinged to the said frames, the vibrateing action being conveyed to the said
spindles by means of a hinged connecting or driveing rod, worked by a crank
shaft, or eccentric action, which can be driven at variable speeds, by a pully
at either end of the crank shaft as may be desired, the resulting action of the
crank bearing, or eccentric with the hinged connecting rod attached to the upper
part of one of the said vibrateing spindles to which the frames are fastened, is
the production of a vibrateing, shakeing, or jogging motion, of the two or more
seives, each seive vibrateing or shakeing in an opposite direction, thus rapidly
sifting the flour, powder, or other material conveyed to the seives by a feed
hopper.
upper, and
We now proceed to explain the principle by which the mixing, or blending, of
the flour, powder or other material, is produced.
Between the before mentioned
lower seives, is placed
a vibrateing, slopeing platform, made of wood, 01' other suitable
material, on which the flour or other material, in the act of being
sifted falls, this said platform, vibrates with the upper seive and being fixed,
slopeing towards the head of the under seive, the material passing over it, is
carried back to the head of the under seive next below, where it is again thus
mixed, and sifted and is passed from one seive to the other, to any desired
number or fineness of mesh, and is thus continually being mixed, and blended,
as often as desired.
a
As a further aid to the efficient, or effective, mixing or blending of the
material being treated, we attach to the bottom of the vibrateing platform,
series of wood, or metal bars, which vibrate in opposite direction to the seive
directly under, and thus stir, and keep in a state of agitation, the material in
process of being mixed, or blended, and at the same time keeping the mesh of
the under seive from clogging, to prevent any crushing of foreign matter that
may have passed through the mesh of the upper seive, through being mixed
with the flour, powder or other material being treated by this machine, the
aforsaid bars are placed a height above the mesh of the under seive, slightly

page_text: over the size of the opening of the mesh of the upper seive and thus it can
and will, pass under the bars, and so escape by gently passing over the tail
of the under seive, into a shoot or spout, placed to receive it.
Similar tailing over action is provided from the upper seive, for larger or
coarser foreign matter falling on it, the same being carried into the before
mentioned spout or shoot, the upper seive is also provided with wood or metal
bars, placed across its upper surface, which vibrate with the seive, and are so
placed for the purpose of assisting the inflow, of and gently distributing, the
Hour, powder or other material over the surface of the seive, and disintegrating
or seperateing the material in its first stage of sifting, and blending, the said
bars however are fixed at suffecient height above the surface of the upper sieve,
as not to unduly crush, or break any foreign matter falling on it.
The seives, and frames, as described are all enclosed, within a cover or caseing,
of wood or other material and fitted to its upper side, is a slide of metal or
wood, to regulate the inflow, or feed, from the hopper from which the flour,
powder, or other material, is passed into the machine.

An Improved Apparatus for Rapidly Sifting, Mixing, and Blending
Flour Meal, Powders, Grain, Seeds, and the like.
We, GEORGE GARNISH and JOHN ROCK LEMON, both Millwrights and Engineers,
of Pilton, Barnstaple, in the County of Devon, and JOSEPH ABELL ELLACOTT,
Flour Salesman, of the Hermitage, Exwick, in the County of Devon, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
:-
The apparatus which constitutes this invention consists of a machine for
rapidly mixing, seiving or sifting and in one operation thoroughly mixing or blend-
ing two or more kinds of flour powder seeds silicitous sands or any like or similar
material, by the means of two or more seives of different mesh of increased
fineness, placed over each other and attached to two or more vibrateing frames,
hung or held in position by two or more specially designed vibrateing or rocking
spindles, hinged to the said frames, the vibrateing action being conveyed to the
said spindles by means of a hinged connecting or driveing rod worked by a
crank shaft or eccentric action, which can be driven at variable speeds by a
pulley at either end of the crank shaft as may be desired, the resulting action
of the crank or eccentric bearing with the hinged connecting rod attached to
one of the said vibrateing or rocking spindles to which the frames are hinged,
is the production of a vibrating, shakeing, jogging or rocking motion, on the
two or more seives, each seive vibrating rocking or shakeing in an opposite
direction, thus rapidly, sifting, mixing and blending, the flour, powder, sand
or other material, conveyed to the seives, by a feed hopper, which is fitted with
a slide for regulateing the feed.
We now proceed to explain the principle by which the mixing or blending of
the flour, powder, sand or other material is produced.
mentioned upper and lower seives is placed a vibrating slopeing platform made
Between the before
of wood or other suitable material, on which the flour or similar material falls

page_text: after passing through the top seive or riddle, this platform vibrates with and at
the same speed as the upper seive and is fixed slopeing towards the head of the
under seive, and thus the matérial being sifted, is most thoroughly mixed together
be it of two or more kinds, as it passes from seive to seive to any number or
desired finess of mesh. As a further aid and effective finish to thoroughly blend-
ing, the material in the process of mixing, we attach to the bottom of the
vibrating platform a series of wood or metal bars, which vibrate in opposite
direction to the seive directly under, and thus stir and keep in a dancing motion
the material in process of being mixed or blended, and at the same time and
by the same action keeping the mesh of the under seive from clogging.
it.
To prevent any crushing of foreign matter that may have passed through
the mesh of the upper seive through being mixed with the flour, powder, or
other material being treated by this machine, the aforsaid bars are placed at
a height above the surface of the under seive slightly higher than the width
of the opening of the mesh of the seive or riddle above it and thus the foreign
matter referred to above can and will pass under the bars, and so escape by
passing over the tail of the under seive into a spout or shoot placed to receive
A similar tailing over action is provided from the upper seive or riddle for
larger or coarser foreign matter falling on it, the same being carried into the
before mentioned spout or shoot. The upper seive or riddle is also provided
with wood or metal bars placed across its upper surface which vibrate with the
seive and is so placed to assist the inflow of and evenly distributing the material
being treated by the machine, by disentegrating or seperateing the same in
its first stage of sifting & blending. The said bars are however fixed at sufficient
height above the upper seive, as not to unduly crush or break any foreign
matter falling on it. The seives and frames as above described are all enclosed
within a cover or caseing of wood or other material, and fitted to its upper side
is a slide of wood or metal to regulate the inflow of the flour powder sand or
other material being fed into the machine, from the hopper or other receptacle
placed above it.
Referring to the accompanying sheet of illustrations or drawings, Fig. 1 repre-
sents in plan an example of our apparatus for sifting and blending flour meal
powders sands or other and similar material. Fig. 2 is a longitudinal section
on the line - Fig. 1.
The apparatus consists of two sifting boxes a al fitted with seives b and c
the upper seive b can be drawn out endways by means of the handle 61 for
the convenience of cleaning, the seive c is of finer mesh than seive 5 which
for the purpose of avoiding complication in the drawings is not shown at Fig. 1
but is diagrammatically at Fig. 2.
The iron rocker spindles e are attached to a frame d of wood iron or steel
by means of the iron brackets or journals f, these brackets or journals are bolted
to the top of the sides of the frame d and the sifting boxes a a1 are hinged
to the rocker spindles e by means of metal pins g fastened with set screws h.
The crank shaft i is supported in brackets or journals j bolted to the frame d,
crank block k in the centre of crank shaft i is fastened to a connecting rod
by means of a screw and lock nut and the connecting rod is hinged to the arm
of the rocker spindle c by means of a hook n rotated by turning the crank
shaft which gives a rotary, rocking or reciprocateing motion to the sifting
boxes a al the balance wheel o is to balance or counteract the throw of the
crank.
C
p is a slide or platform fixed in a slopeing position to carry the material
passing through the upper seive or riddle b back to the head of bottom seive c
and made to draw out endways by means of the handle o 1.
The pulley q
is the tight pulley and g 1 the loose pulley. Material to be dealt with is charged
into the upper sifting box a and seive 6 where by operation of the apparatus
it is sifted. Such material as passes through the upper seive b is received

page_text: on the slide or platform p and thence to the head of bottom seive c and is
there finally treated, by the flour or other finer material passing through the
finer mesh or the foreign matter tailing over into the shoot or spout placed to
receive it.
To assist in agitating the material and to mix and blend it, transverse bars
of wood or metal are fixed over the upper surface of the bottom seive c, but
are attached to the top seive b, by boards or sides of platform s, bolted to the
bottom of sifting box a, and so vibrates with the top sieve b, and in opposite
direction to the bottom seive c. Transverse bars of wood 'or metal are also
fixed over the face of the upper seive b, which therefore vibrate with upper
seive box ab.
Cover u of which a longitudinal section is shewn in Fig. 3, is provided to
fit over boxes a al and rest on the side beams of the frame d, the cover u
being held in its place by means of the ledge or stops u1, the cover has a
hopper for chargeing into the box a the flour or other material to be acted
upon by the machine and under the hopper is placed a slide w with a horn
nut w and brackets w2, for regulating the feed to the sifting box a and
upper seive b.
The action of the apparatus is a rapid and no crushing effect is exerted on the
material so that all foreign matter not of the nature of flour powder or sand
of size fine enough to pass through the under seive, is delivered as it falls
into the machine, by gently passing over the tails or lower ends of each of the
two seives.
In adapting the apparatus for manual operation a standard and pulley is
fixed over the crank shaft to which is attached a handle and belt or chain
for driveing this is not shewn on the drawing.
Having now particularly described and ascertained the nature of this our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :.
An apparatus for sifting flour meal, grain, seed and the like or sand and
other selicitious substances, consisting of boxes such "a a 1" open at top and
bottom fitted with, a seive such as band a seive such as e of finer mesh fixed
below seive b, the said boxes being connected to a frame or other support by
rocking spindles such as c so hung as to vibrate by means of a crank shaft
such as i, a crank block such as k, which gives a rapid rocking, vibrateing and
reciprocateing motion on seives b and c, and for mixing flour meal, grain seed
and the like, sand or other selicitious substances by stirring and agitating same
while being sifted by means of bars, such as t extending transversly over the
face of the lower and upper seives, and reciprocating in opposite directions
through the medium of connecting rod such as 1, crank such as i and rocker
spindles such as e substantially as hereinabove discribed with reference to the
accompanying sheet of illustrative, drawings.
