page_text: I, William BeaTTIE, of Dennistoun Bakery, in the County of the City of
Glasgow, North Britain, Baker, do hereby declare the nature of this invention
to be as follows:-
This invention relates to a kneading machine for use in bakeries. In
bakeries, where large quantities of dough has to be kneaded, this is done by
men tramping about the trough in which the dough is placed. The object of
this invention is to accomplish the kneading by machinery.
In carrying out my invention I employ a number of kneading stamps which
may be about the weight of a man. These kneading stamps are carried by a
beam or girder which can be moved up and down by any convenient machinery
in guides in the framework of the machine. The kneading trough is placed
underneath the stamps and the girder carrying the stamp is caused to move
down and up in order to bring the stamps down to and away from the dough.
Each stamp is hung from the girder by a flange attached to the top of a spindle,
which passes loosely through the girder so that when the stamps come in contact
with the dough they only press with their own weight and are not pushed down
by the girder, but when the girder rises it lifts the stamps with it. The stamps
may be of oblong shape and can be turned round to any required angle by
means of levers connected to the spindles.

I, WILLIAM BEATTIE, of Dennistoun Bakery, in the County of the City of
Glasgow, North Britain. Baker, 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 a kneading machine for use in bakeries. In
bakeries, where large quantities of dough has to be kneaded, this is done by
men tramping about the trough in which the dough is placed. The object of
this invention is to accomplish the kneading by machinery.
In carrying out my invention I employ a number of kneading stamps which
may be about the weight of a man. These kneading stamps are carried by a
beam or girder which can be moved up and down by any convenient machinery

page_text: in guides in the framework of the machine. The kneading trough is placed
underneath the stamps and the girder carrying the stamp is caused to move
down and up in order to bring the stamps down to and away from the dough
after it has been made by the mixing machine or by hand and immediately
before cutting up into loaves. Each stamp is hung from the girder by a flange
attached to the top of a spindle, which passes loosely through the girder so that
when the stamps come in contact with the dough they only press with their
own weight and are not pushed down by the girder, but when the girder rises it
lifts the stamp with it. The stamps may be of oblong shape and can be turned
round to any required angle by means of levers connected to the spindles.
In order that my invention may, be properly understood and readily carried
into effect I have hereunto 'appended one slicet of drawings, of which,
Figure 1 is a front elevation of the kneading machine.
Figure 2 is a part plan of the girder and mechanism for altering the angle
of the stamp or plunger.
Figure 3 is also a part plan of one end of the girder and guide arrangement,
and'
Figure 4 is a perspective view of the kneading stamp or plunger all hereafter
more fully referred to.
In the drawings, the kneading stamps or plungers A (which are four in number
though a greater or less number may be employed) are disposed along the
girder B to which they are suspended at suitable distances apart by means of
the nuts a screwed on to the top of the spindles or shanks C which are bolted cr
otherwise secured to the said stamps or plungers A. The said nuts a rest upon
the top of the levers D and D¹, which again are supported by plates bolted to
the upper side of the girder aforesaid. The centres of the levers D, D which
form a part of the mechanism by which the stamps or plungers A are controlled,
constitute bushes in which the spindles or shanks of the stamps are free to
move up and down. The stamps or plungers A are preferably faced with wood
as shewn in Figures 1 and 4. The mechanism by which the stamps or plungers
are controlled in relation to the angle or horizontal position they may be in
when entering the dough which is placed in the trough or other receptacle A¹
used in the kneading operation, consists of a pair of single levers D, D, and a
pair of double levers D¹, D'. The two opposite pairs of double levers D¹, D¹,
are connected at their outer ends by a long connecting rod or bar G. The single
levers D, D, are each connected to the double levers D¹, D¹, aforesaid at their
opposite ends respectively by two short links or connecting rods G¹, as seen in
Figure 2.
The spindle or shank C of each stamp or plunger is formed with a longitudinal
groove el, seen in Figure 4. Working in this groove is a set pin, stud or bolt H,
which is screwed transversely into the bush portion of the single and double
levers respectively.
By virtue of the said groove and pin the rise and fall of each or any of the
stamps or plungers is permitted without any alteration to the angular position of
the said stamps or plungers. When the stamps come in contact with the dough
they only press with their own weight, as shown in Figure 1.
Each of the outer stamps or plungers is provided with a handle a' by which
the angular position of the stamps or plungers is changed at will by the attendant
or operator.
The weight of the girder, with the stamps or plungers and controlling
mechanism, is somewhat counterbalanced by the weights I, I, which are con-
nected to the said girder by the wire ropes J, J, which pass over suitable pulleys,
not shewn in the drawings, mounted near the ceiling of the building in which
the machine is used. The ropes N, N, act as guides for the weights I, I.
The girder B is connected to the power or actuating mechanism, preferably
hydraulic (also not shewn in the drawings) though any other suitable power
or motor may be employed, by means of the wire ropes, cords, or chains K, K,

page_text: which pass under the pulleys L, L, connected to said girder. These pulleys
are provided with shanks or stems 1, 1, which pass through the guide blocks A
of the girder. The lower end of the shanks or stems l, l, are provided with
screw nuts n, n, between which and the underside of the girder B are interposed
the spiral springs o, o. These springs retard the vibration and shock consequent
upon any undue, rapid, and violent descent of the girder, and allow the pull of
the wire ropes in raising the girder and withdrawing the stamps or plungers
from the dough to come on gradually and thereby minimise undue strain.
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
1. The machine for kneading dough, substantially as described and illustrated
on the accompanying sheet of drawings.
2. The application of mechanism to stamping or kneading the dough in
trough after it has been made by the mixing machine or by hand and immedi-
ately before cutting up into loaves, substantially as described and illustrated
on the accompanying sheet of drawings.
