I, REGINALD HADDAN of the firm of Herbert & Co. Patent Agents of 18
Buckingham Street Strand W.C. London in the County of Middlesex Civil Engineer
do hereby declare the nature of this invention, a communication to me from abroad by
Juan Segui y Barenys of Lérida in the Kingdom of Spain, Manufacturer, 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 kneading machines and consists in certain improvements
therein as hereinafter described with reference to the accompanying drawings in
which,
Fig. 1 is a plan view of the improved kneading machine.
Fig. 2 an elevation thereof, partly in section.
Figs. 3 and 4 opposite end elevations.
Fig. 5 a section on line X Y Fig. 1.
Fig. 6 and 7 illustrate modifications.
The improved machine consists of two troughs of usual construction placed side by
side so as to form a receptacle of about 2 metres length by 1 metre breadth. The
size of the troughs may however vary according to requirement.
They are separated by a partition ab which does not extend to the ends of the
trough, spaces a c, b d being left for communication between the ends of the troughs,
and for the passage of the spade wheels A A¹. The two troughs are not equal in size,
the one in which the dough is kneaded or mixed cdef is slightly smaller than the
other cd hg in which the dough is more at rest, they are also not of uniform breadth
throughout their length, each being gradually narrowed from one end to the other
inversely to the other trough, the difference in width of the ends varying according to
requirement. The bottoms of the troughs are cylindrical and inclined in opposite
directions in the direction of their length.
In the smaller trough is journalled lengthwise thereof a spiral screw H of the shape
substantially as shown. This screw may be actuated by suitable gear and is adapted,
when it is turned, to move the dough from the higher to the lower end of the trough.
At each end of the larger trough are journalled in the axis of the trough spade wheels
or rotary propellers AA' provided with curved spiral blades as shown. The said

page_text: wheels revolve in contrary directions and are actuated by suitable gear. The outer
edge of each spade and also the edge of the screw H are serrated or indented so that
the teeth on the one may pass between those on the other.
The machine works as follows;-The screw H actuated by suitable gear, works the
dough in the trough cdef carrying it also from the end de to the end cf, the
inclination of the trough facilitating this movement. As the dough arrives at cf it is
taken by the spade wheel A and carried into the larger trough chgd, being there
partially worked by the said wheel. The inclination of the trough and the pressure
of the dough arriving in the trough causes the same to pass along the trough chgd
to the spade wheel A, the latter works the dough and transfers it again into the
first trough. It is obvious that only part of the dough is worked by the screw, at any
time, the greater part being substantially at rest in the larger trough. The wheels A A¹
having a greater range of radial parts draw out and refine the dough exposing it to
the atmosphere.
To adapt the improvements to machines for working soft or hard dough respectively,
modifications are made as shown in Figs. 6 and 7.
For soft dough the screw H is replaced by two spade wheels A" A¹¹ journalled
respectively one across each trough and operated by suitable gear. The edges of the
spados conform to the cross section of the floor of the trough, they being preferably
serrated or indented.
For hard dough the wheels AA¹ are replaced by another screw H¹ Fig. 7, journalled
longitudinally in the larger trough.
The parts of the trough, screws and spade wheels should be made of or covered
with material which is a bad conductor of heat.
The improved kneading machine may be adapted to starch and gluten making,
by arranging above one of the troughs a suitable pipe perforated to permit the
liquid therein to fall in thin streams into the trough. The water with suspended
flour therein is fed through this pipe and falls therefrom into the trough. The bottom
of the latter is provided with a perforated portion so that the liquid containing the
starch in solution may be drawn or pass off into suitable receptacles placed to
receive it. The solid matter mostly gluten remaining on the sieve and being passed
from trough to trough in the same manner as the dough aforesaid. There may be
suitable devices for closing the sieve and retaining the liquid in the trough if desired
for a preliminary working of the flour in the water. After the water is drawn off
the gluten passes through the troughs as aforesaid.
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.;=-
In kneading machines
1. The combination of two troughs placed beside each other said troughs being
shaped substantially as set forth.
2. The combination with two troughs substantially as set forth, of a screw H and
spade wheels A A¹.
3. The combination with two troughs substantially as set forth of two screws HH¹.
4. The combination with two troughs substantially as set forth, of spade
wheels A A¹ A¹¹ A¹¹¹.
5. The combination with two troughs substantially as set forth, of two spade
wheels A A¹.
6. The combination with two troughs and kneading devices therein, of a pipe and
sieve substantially as and for the purpose set forth.
