An Improved Spiral Mixing Machine for Liquidising or
Incorporating Mixable Ingredients.
THOMAS LOWE of 40 Bramerton Street Chelsea in the County of Middlesex
Practical Engineer. I, Thomas Lowe, do hereby declare the nature of this invention
to be as follows:-
My invention consists in fitting and bolting together two vertical side frames to a sole-
plate with socket forming a bottom, on which I mount a cylindrical flanged pipe or
barrel which is bolted through the flange to the sole-plate. The top of the barrel is
fixed to the side frames by suited brackets. The side frames at the top are rigidly
bolted together with a cross-bracket bored and bushed to receive two shafts one
vertical and one horizontal. On the outside of one of the side frames a shaft is fixed
horizontally, carrying the loose pulley, and the driving pulley with pinion attached.
The pinion is geared into and imparts motion to a spur wheel keyed on the horizontal
shaft above, and gives motion to a bevel pinion which is geared into two other bevel
wheels, which impart motion to the vertical shaft on the one part, and a revolving
bracket on the other part, causing them to move in opposite directions forming a
reverse lateral action. The vertical shaft is fitted into the socket of the sole plate
and has a solid collar near the bottom which rests on the socket boss, and also a
movable collar that takes into the revolving bracket, from the bottom collar upward
to the movable collar the vertical shaft is left square, on this square portion of this
said shaft I fit a series of star knives, the axis of these knives are formed with square
holes to slide on the square part of the said shaft, each knife has four blades are
dagger shaped with inclined planes, the axis of each knife is divided into four parts
each part forming a seperate knife blade at right angles and rise one above each
other. The square hole of the axis of each knife is changed one degree, thus forming
five seperate spiral actions four rapid and one slow, while gravitation operating forms
a reverse vertical action. The revolving bracket has two rows of knives similar to
the star knives, which are arranged to pass through closely between each star knife
fitted on the vertical shaft. The frame of the said revolving bracket works close to

page_text: the interior of the barrel and is keen edged with inclined planes. At the top of the
revolving bracket a long boss (cored to allow the vertical shaft to work free is.
extended upward terminating with a half coupling, the bevel wheel with similar half
coupling attached is bored a working fit to the vertical shaft and bolted rigidly to
the revolving bracket. The vertical shaft is held in the desired position by a bearing
in the cross-bracket and the bottom end fitted into the socket of the sole-plate, and is
sustained by the movable collar which is a working fit in the bottom of the long boss
of the revolving bracket. The movable collar is pinned to the vertical shaft and fixes
the star knives on the vertical shaft, and also fixes the vertical shaft carrying the star
knives and the revolving bracket substantially together, leaving them free to work.
The revolving bracket is held in the desired position and revolves oppositely round
the vertical shaft at the top and the solid collar on the said shaft at the bottom, and is
sustained by and revolves round the movable collar pinned to the vertical shaft. The
vertical shaft and the revolving bracket (driven by one pinion) are mounted with
similar bevel wheels. The horizontal shaft at the top works in brass bearing and
bush and is held in the desired position by collars fitted with set-screws. The outlet
to be a slide or flap door in the bottom or other suitable part.

THOMAS LOWE of 40 Bramerton Street Chelsea in the County of Middlesex
Practical Engineer. I, Thomas Lowe, 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 :-
My Invention consists in fitting and bolting together two vertical side frames to a
sole-plate with socket forming a bottom, on which I mount a cylindrical flanged pipe
or barrel which is bolted through the flange to the sole-plate. The top of the barrel
is fixed to the side frames by suited brackets. The side frames at the top are
rigidly bolted together with a cross-bracket, bored and bushed to receive two shafts,"
one vertical, and one horizontal. On the outside of one of the side frames, a shaft is
fixed horizontally, carrying the loose pulley, and the driving pulley with pinion
attached. The pinion is geared into and imparts motion to a spur wheel keyed on the
horizontal shaft above, and gives motion to a bevel pinion which is geared into two
other bevel wheels, which impart motion to the vertical shaft (on the one part), and a
revolving bracket (on the other part), causing them to move in opposite directions
forming a reverse lateral action. The vertical shaft is fitted into the socket of the
sole-plate, and has a solid collar near the bottom which rests on the socket boss, and
also a movable collar that takes into the revolving bracket, from the bottom collar
upward to the movable collar the vertical shaft is left square, on this square portion
of this said shaft, I fit a series of star knives, the axis of these knives are formed with
square holes to slide on the square part of the said shaft, each knife has four blades,
are dagger shaped with inclined planes, the axis of each knife is divided into four
parts, each part forming a seperate knife blade at right angles, and rise one above
each other. The square hole of the axis of each knife is changed 1 degree, thus
forming five seperate spiral actions, four rapid, and one slow, while gravitation
operating, forms a reverse vertical action. The revolving bracket has two rows of
knives similar to the star knives, which are arranged to pass through closely between
each star knife fitted on the vertical shaft, the frame of the said revolving bracket
works close to the interior of the barrel, and is keen edged, with inclined planes, at
the top of the revolving bracket a long boss (cored to allow the vertical shaft to work
free), is extended upward terminating with a half coupling. The bevel wheel
with similar half coupling attached is bored a working fit to the vertical shaft,
and bolted rigidly to the revolving bracket. The vertical shaft is held in the
desired position by a bearing in the cross-bracket, and the bottom end fitted into
the socket of the sole-plate, and is sustained by the movable collar, which is a working
fit in the bottom of the long boss of the revolving bracket. The movable collar is
pinned to the vertical shaft, and fixes the star knives on the vertical shaft, and also

page_text: fixes the vertical shaft carrying the star knives and the revolving bracket substantially
together, leaving them free to work. The revolving bracket is held in the desired
position, and revolves oppositely round the vertical shaft at the top, and the solid
collar on the said shaft at the bottom, and is sustained by and revolves round the
movable collar pinned to the vertical shaft. The vertical shaft and the revolving
bracket driven by one pinion are mounted with similar bevel wheels. The horizontal
shaft at the top works in brass bearing and bush, and is held in the desired position
by collars fitted with set-screws. The outlet to be a slide or flap door, in the bottom
or other suitable part.
All acting substantially as herein described.
Reference being had to the accompanying Drawings hereunto annexed, that is
to say..
On a sole-plate S, I mount two vertical side frames T, T, a cylinder R, and cross-
bracket I, forming a base and frame of the mechanism. On the outside of one of the
side frames T, I fix a horizontal pin shaft A, with a solid collar on the outside, and a
nut and washer on the inside, and a movable collar with set-screw at the end, to keep
the pulleys B, and C, in the desired position, the said pin shaft A, carries the loose
pulley B, and the driving pulley C with pinion C¹ attached, whereby motion is
imparted to the spur wheel D, which is keyed to the above horizontal shaft E, which
carries the driving bevel pinion F, and also a collar G to keep it in the desired
position, and rests or revolves in a brass bearing H, and a bushed bearing H' in the
cross-bracket 1, the bevel pinion F is geared into two other bevel wheels K, and the
half coupled wheel L, thus motion (on the one part), is imparted to the bevel wheel K,
which is keyed to the vertical shaft M carrying the star knives N which form the
spiral action, and move in one direction, (and on the other part) at the same time
imparting motion to the half coupled bevel wheel L, which is rigidly coupled at O¹
to a revolving bracket O, (furnished with knives O₁ similar to the star knives N),
causing the bracket O to move in an opposite direction, forming a reverse lateral
action. The bottom of the long boss O2 of the bracket O, is recessed at 0³, to receive
the movable collar P pinned on the vertical shaft M, to prevent vibration, the movable
collar P pinned in this desired position, fixes rigidly the star knives N on the square
portion of the vertical shaft M, and also couples the vertical shaft M carrying the
star knives N and the revolving bracket O substantially together, leaving them free
to work, and capable of being lifted out in one piece for cleaning or clearing. The
vertical shaft M is held and works in the socket S¹ and the cross-bracket I which are
bored to receive it, the lower end bottoms in the hole of the socket S¹, and the solid
collar M¹ rests upon the boss of the socket S¹, partly bearing the weight, and dividing
the friction. The revolving bracket O, revolves oppositely round the vertical shaft M
at the coupled bevel wheel L, and the solid collar M', and the movable collar P. The
collar P is arranged to partly bear the weight while the bottom boss of the revolving
bracket O rests upon the socket boss S¹ also partly bearing the weight, and dividing
the friction. The working parts of the revolving bracket O, are chamfered to a keen
edge, and revolve close to the interior of the cylinder R, and the bottom or sole-
plate S. The cylinder R, is flanged R', on the outer side at the bottom, and rigidly
bolted through the flange to the sole-plate S, and bolted at the top to the side
frames T, T, by suited brackets T T', to prevent vibration. The sole-plate S, a square
plate has a planed seating for the flange R¹ of the cylinder R, and has four upstanding
lugs S³, near the corners, to which the side frames T, T, are bolted to bring them to
the desired position, and prevent vibration. On the outside of the lugs S³, are chipping-
piece seatings S, on which the side frames T, T, sit and are bolted. The sole-plate S
is fitted with a slide or flap outlet S2, worked by a screw and hand wheel, and placed
at the bottom or other suitable part of the cylinder R. The side frames T, T, are
furnished with chipping piece bottoms S, side lug seatings S³, seatings for the
cylinder brackets T, T, and the cross-bracket I at the top, which are planed surfaces.
One of the frames T has a boss bored to receive the horizontal pin shaft A, and a brass
bearing at the top. The side frames T, T, are slightly inclined upward front view,
and take the form of the letter A side view, for strength.

page_text: Figure 1, of the accompanying Drawings illustrates the method of carrying my
Invention into effect, and the bottom star knife N in its position. N, N, N, N, N, are
spaces to be occupied by similar star knives, each knife to be changed 1 degree,
(see Fig. 3).
Figure 2, illustrates the side view of one of the star knives, out of position.
Figure 3, illustrates the top view of one of the star knives out of position. The
point of square hole or core moved to the dots or degrees in the direction of arrow,
illustrates the method of obtaining the spiral action, for the lift, and dispersion, of
weighty sediments.
The action is as follows. On the driving belt being shifted from the loose pulley B,
to the driving pulley C with pinion (2 attached, motion is imparted to the spur
wheel D, which is keyed to the horizontal shaft E, giving motion to the bevel pinion F,
which imparts motion to the bevel wheel K keyed on the vertical shaft M, and the
bevel wheel L coupled to the revolving bracket O, causing them to revolve in opposite.
directions, producing a reverse lateral action. The star knives N fitted on the vertical'
shaft M (arranged as before described), form five spirals, four rapid, and one slow,
which lift the ingredients, while gravitation operating produces a reverse vertical
action. The outlet S to be a slide or flap door, in the sole-plate S, or other suitable
part, and worked by a screw and hand wheel. The action to be made reversible, by
crossing the belt.
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 ;
