GEORGE LISTER Millwright & Machinist 3 Austin Friars Stamford Lincolnshire do
hereby declare the nature of this invention to be as follows:-
This invention is an improved feeding and mixing machine, for feeding and mixing,
Meal, Flour, Middlings and all like inaterials.
The hopper or body of the machine is made and put together in parts, the right
hand side, left side, front, and hack, these are put together by means of screws, as
is also the mouthpeice, which projects in front, this is screwed to the bottom and also
to the machine front by means of screws, this mouthpeice has a Glass door which
opens in front of the inachine on the top of mouthpeice so that the machine can be
seen when in motion feeding or mixing &c. &c.
The machine has a shaft which runs through it close to the front, It runs in two
bearings ono on each side the machine, It is the driving shaft. On this shaft is keyed
an Excentric close to the bearing, the throw of this Excentric works the lever which
is refered to below, The driving pulley is also keyed on this shaft, The Excentric before
refered to has a strap which is joined together in two halfs by two bolts, round the
Excentric, the Excentric as two flanges which act as a guide for the strap, this strap
is fitted loosely round the Excentric to allow it to work free, to this strap is connected
a link, screwed into the Excentric strap there is a lever fastened to the machine
side by means of a stud which is firmly screwed up to a collar or shoulder to allow
the link free action to work, this lever has two slots one in each end, the link above
refered to is connected to this lever by means of a pin which runs through the
link and the slot of the lever, the link having a slot down the end of it, so that the
lever works in the centre of the link with the jaw of the link on cach side the lever,
the pin above refered to which connects the link to the lever has a hole through the
centre of it, into which is tapped the screw which runs through the lever end and
down the slot, This screw has a collar on it so as to keep it in its place in the lever,
at the other end of the lever there is also a link connected to this end with a pin in
the same manner as the other side link, The bottom end of this link is connected
to a pair of arms by means of a pin these arms have holes in the ends of them,
which are fitted loosely round the bosses of the ratchet wheel so as to work freely
round it, this ratchet is keyed on a shaft which runs at the back of the machine, this
shaft has two bearings screwed to the back of the machine, the arms above refered
to have a catch which when the machine is in motion drops in the ratchet wheel
teeth, by altering the screws above refered to which runs through the slot of the
lever, and connects the links to the lever can be regulated by screwing the link
marked on the drawing I. from the centre of the lever to the other end of the slot,
and the link N, to the centre of the lever the catch will drop in only one of the
teeth of the ratchet wheel, to one revolution of the main or driving shaft and by
screwing the link I. to the centre and the link N. from the centre the catch will drop
into 12 or more of the teeth on the ratchet wheel, There are also on this shaft which
runs at the back of the machine 2 pinions these pinions are fastened on the Shaft,
there are two worms in the machine (or more if required) which runs from the back
of the machine to the front of the mouthpeice these worms are very fine pitch, so
that when the machine is full of feed they will take very little driving, these worms
run in bearings one on (front & back) of the machine each end of the worms and are
screwed to the machine, at the back of the machine there are two pinions on the end
of the worms which projects out of the bearings, these pinions run in and are driven
by the pinions on the shaft which runs at the back of the machine, one of these pinions

page_text: on this shaft can be sliped out of gear by unscrewing the screw in the pinion and
sliped back on the shaft so that if required one of the worms can be run at once, thus
when the machine is working at one catch or tooth per revelution of the main shaft
with one worm and by altering the screws to take 12 teeth with 2 worms the machine
will do 24 times the amount of work as when working at the one tooth, the screws
can be altered when the machine is in motion, and can be altered so that it will take
from the one tooth upwards to the 12 or more if required according to the amount
of materials to he fed or mixed as required, there is a division board down the centre
of the machine which divides the two worins thus this machine can be used to feed
two machines at the same time, thus doing the work of two of the old machines,
the division board can be taken out or put in when required, when the division board
is out it throws the machine into one, there is a mouthpeice for the spout to be fitted
to under the machine bottom.

GEORGE LISTER Millwright & Machinist No. 3 Austin Friars Stamford Lincolnshire
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:
This invention is an improved feeding and mixing machine for meal flour
middlings &c. &c. It is so constructed as to be able to feed & mix either fast or
slow when running at the same speed, without wasteing any of the materials which
is passing through it &c. &c.
This invention is an improved feeding and mixing machine for feeding & mixing,
Meal, Flour, Middlings, and all like materials for use in Corn Mills, Steam Bakerios
and Spice Mills.
DESCRIPTION OF INVENTION.
The hopper or body of this machine is made and put together in parts, the right
hand side, left side front, and back, these are put together by screws as is also the
mouthpoice which projects in front, this is screwed to the bottom and also to the
machine, on the top of this mouthpeice there is a Glass door which opens in front so
that the machine can be seen feeding or mixing.
This machine unlike the old machines as a fast bottom which is screwed to the
hopper, so that there cannot be any waste of the materials which are passing through
the machine as is the case in the Old machine, this machine has a shaft or spindle
which runs through it close to the front, it runs in 2 bearings one on each side of
the machine this is the driving shaft there is an excentric keyed on it close to the
bearing the throw of this Excentric works the lever which is referred to below,
the driving pulley is keyed on this shaft, this is the pulley which drives the machine,
the excentric above referred to has a strap which is joined together in 2. halfs by
2 bolts, round the Excentric, the excentric bas 2 flanges which act as a guide for the
strap, this strap is fitted loosely round the excentric to allow it to work freely to this
strap is connected a link, screwed into the excentric strap, there is a lever held to
the machine side by means of a stud which is firmly screwed up to a collar or
shoulder to allow the lever free action to work, this lever has 2 slots one in each
ond, the link above referred to is connected to this lever by means of a pin which
runs through the link and the slot of the lever, the link having a slot down the end
of it, so that the lever works in the centre of the link with a jaw of the link on
each side the lever, this pin before referred to which connects the link and the lever
has a hole through the centre of it, into which is tapped a screw which runs through
the lever end and down the slot, this screw has a collar on it so as to keep the

page_text: screw in its place in the lever, at the other end of the lever there is also a link
connected with a pin in the same manner as the other side link, the bottom end
of this link is connected to a pair of arms by means of a pin through the arms and
link these arms have holes in the ends of them which are fitted loosely round the
bosses of the ratchet so as to work freely round it, the ratchet is keyed on the end of
a shaft which runs at the back of the machine this shaft has 2 bearings screwed to
the back of the machine the arms before referred to have a catch which when the
machine is in motion drops in the teeth of the ratchet wheel, by altering the screws
before referred to which runs through the slot in the lever and connects the links to
the lever can be regulated by screwing the link marked on the drawings 1. from the
centre of the lever to the other end of the slot, and the link N. to the centre of the
lever the catch will drop in only one of the teeth of the ratchet wheel, to one revolu-
tion of the driving shaft or spindle, and by screwing the link I. to the centre and
the link N. from the centre, the catch will drop into 12 or more if required, of the
teeth of the ratchet to one revolution of the driving shaft, there are also on this
shaft which runs at the back of the machine 2 pinions, there are 2 worm conveyors in
the machine which run from the back of the machine to the front of the mouthpeice
these worms bring the materials from the back to the front they are very fine pitch
so as to take litte power driving these worms run in bearings one at each end of the
worms, the bearings are screwed to the machine, at the back of the machine there are
2 pinions one on the end of each of the worms which project out of the bearings,
these pinions run in and are driven by the pinions on the shaft or spindle at the back
of the machine, one of these pinions can be slipped out of gear by unscrewing the
screw in the pinion and slipping it back on the shaft, so that if required one of the
worms can be run at once, thus when the machine is working at one catch or tooth
per revolution of the driving shaft or spindle, with one worm, and by altering the
screws to take 12 teeth with 2 worms the machine will do 24 times the amount of
work as when working at the one tooth, the screws can be altered so that it will take
from the one tooth upwards to the 12 (when the machine is in motion) or more if
required according to the amount of materials to be fed or mixed, there is a division
board down the centre of the machine which divides the two worms thus this machine
can be used to feed 2 machines at the same time, thus doing the work and answering
the same purpose of 2 of the Old machines the division board can be taken out when
required or put in, when the division board is out it throws the machine into one, there
is a mouthpeice for the spout to be fitted into at the bottom of the machine so that
there cannot be any waste.
Having now particularly described and ascertained the nature of my said Inven-
tion, and in what manner the same is to be performed 1 declare that what I
claim is :-
--
First. Is the construction of the lever and screws for regulating the feed, and the
connecting arangments of the Excentric, links and ratchet.
Second. Is the fast bottom arrangment, in lieu of a loose bottom.
Third. Is the arrangement of the worm conveyors which are placed so as to bring
the materials from the back of the machine to the mouthpeice.
Fourth. Is the division board down the centre of the machine which make this
machine answer the same purpose as two machines.
Fifth. Is the fine pitch of the worm conveyors to take less driving.
Sixth. A feeding and mixing machine, constructed and arranged substantially as
described.
