Improvements relating to Dough Kneading Machines.
I, RICHARD DEAN, of 1 Dean Terrace, Forest Hill, County of London,
Baker and Confectioner do hereby declare the nature of my invention to be as
follows:-
This invention relates to certain improvements in machines for kneading dough
gradually and effectually, the whole of the meal in the apparatus being acted upon
in a manner following hand labour, instead of the bulk being acted upon at one
time as with existing dough kneaders.
For the purpose of my invention, I construct a cylinder and by a cross bar or
section plate, I suspend a screw or a series of blades therefrom, said screw or
blades being formed from a plate or strip twisted in its length in order to
disperse with a stem or post as part thereof or to which blades could be secured,
the reason for which is; dough has no tendency to clog or adhere, so that the
blades clear themselves as they pass through the dough, the angle being sufficient
for the kneading.
The upper end of the top blade terminates in a pin for carrying a bevil or other
gear which can be put into gear with a wheel operable by hand for rotating the
screw or kneading blades which are arranged about mid-distance between the wall
of the cylinder and its centre or axis.
The cylinder is rotatable by the same outside gear from a platform on which it
can be set, the lower part of the platform being surrounded by a toothed ring
capable of being raised and lowered at will to enable the cylinder to be removed
and another put in its stead if so desired.
By lowering the toothed ring the bottom of the cylinder can readily be drawn
off the platform when it is required to be emptied.
By this invention, only that quantity of meal within range of the screw is being
acted upon but since the cylinder also rotates, the blades always find fresh portions
of the meal to contend with, and a perfect kneading is effected without damage to
the grain, or producing lumps of unkneaded dough, as with existing machines with
screw axially central with the cylinder.

Improvements relating to Dougn Kneading
1, RICHARD DEAN, of 1 Dean Terrace, Forest Hill, County of London,
Baker and Confectioner, 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 relates to certain improvements in machines for kneading dough
gradually and effectually, the whole of the meal in the apparatus being acted upon

page_text: in a manner following hand labour instead of the bulk being acted upon at one time
as with existing dough kneaders.
For the purpose of my invention, I construct a cylinder and by a cross bar or
section plate, I suspend a screw or a series of blades therefrom, said screw or
blades being formed from a plate or strip twisted in its length in order to dispense
with a stem or post as part thereof, on to which blades could be secured, the
reason for which is, dougli has no tendency to clog or adhere, so that the blades
clear themselves as they pass through the dough, the angle being sufficient for the
kneading.
The upper end of the top blade terminates in a pin for carrying a bevel or other
gear which can be put into gear with a wheel operable by hand for rotating the
screw or kneading blades which are arranged about mid-distance between the wall
of the cylinder and its centre or axis.
The cylinder is rotatable by the same outside gear from a platform on which it
can be set, the lower part of the platform being surrounded by a toothed ring
capable of being raised and lowered at will to enable the cylinder to be removed
and another put in in its stead if so desired.
By lowering the toothed ring the bottom of the cylinder can readily be drawn
off the platform when it is required to be emptied.
By this invention, only that quantity of meal within range of the screw is being
acted upon, but since the cylinder also rotates, the blades always find fresh portions
of the meal to contend with and a perfect kneading is effectel without dainage to
the grain, or producing lumps of unkneaded dough as with existing machines with
screw axially, central with the cylinder.
My invention will be more clearly understood by reference to the annexed
drawings, in which
Figure 1 is a
kneader.
transverse vertical section. Figure 2 plan of a cylindrical
Figure 3 longitudinal section of an oval or elongated cylindrical shape of
kneader; Figure 4 being a transverse section of same.
Referring to Figures 1 and 2, A is the cylinder or kneading trough lined with
wood and made up of segments and secured by bolt eyes B, B. This cylinder fits
loosely in a bottom plate C, or rotatable bed on ball bearings D driven by the spur
gear E, F, from a shaft G receiving motion by bevel gear H, H', from the hori
zontal shaft I and pulley J, said shaft being fitted to a bridge K on an up and
down sliding cross stay or carrier guide L which can be moved up and down the
vertical rods or pedestals M, M, the shoulders N, N, of which determine the depth
to which said stay can descend. P is a top girder or stay connecting the upper
ends of the pedestals M, M, and serving to carry pulleys Q, Q, with chains R and
counterweights as a counterpoise to that of the weight of the guide stay L, also
the weight of the bridge K, shaft I, gear H' and pulley J, also the weight of the
bevel gear S, S', and from the latter of which the kneader screw T is suspended by
the spindle U.
V, V, are handles by which the kneading trough A can be lifted from the bed C
after the appliances marked I, J, K, H', S, S¹ and T are raised clear by the chains R
and counterweights.
It will be observed that the kneader T is of such diameter that it just touches
the inside wall of the cylinder A and extends to about the centre of the cylinder
or it may be slightly beyond in order that every particle of flour shall come under
its action while said kneader revolves in one direction and the cylinder A in the
reverse direction, the speed being in such proportion that a perfect kneading is
effected.
According to the modification shown at Figures 3 and 4, the whole of the frame
and the rotating gear is a fixture, and instead of the cylinder revolving as before
it has a reciprocating travel on the rails W by the wheels X, X, under the
direction of the rack Y and spur wheel Z, the reciprocating travel of the cylinder
being governed by the change pulleys a, a, or in any other well known manner.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to he performed I declare that what I
claim is :-
1. The improvements relating to dough kneading machines, as herein before
described and as represented by the annexed drawings.
2. In dough kneading machines, the construction and arrangement of revolving
or rotating cylinder with a revolving or rotating open screw kind of kneader
working within said cylinder as and in the manner described and substantially as
shown at Figures 1 and 2 of the annexed drawings.
3. The modified or reciprocating cylinder or kneading trough with revolving or
rotating open screw shaped kneader, as set forth and shown.
4. A dough kneading apparatus composed of a rotating cylinder removable from
its carrier bed and a removable yet rotatable kneader within and from such cylinder
or kneading trough, the whole arranged and operated in the manner substantially
as described and shown.
