Apparatus for Kneading Dough and the like.
I WILLIAM WILLOTT POPPLEWELL of the firm of Popplewell Colton & Co. of
17 and 18 Southampton Buildings W.C. in the county of Middlesex, Patent Agent,
do hereby declare the nature of this invention to be as follows:―
The apparatus hereinafter described is intended for making dough for bread-.
making on a large scale by means of machinery but may be applied to the kneading
and shaping of any dough-like material by suitably altering the various details
without affecting the general principle or action of the machine.
I provide a casing of uniform height but tapering in width.
At the widest part is a feed hopper and at the opposite or mouth end of the
casing is an intermediary piece or plate dividing the almost eliptically shaped
casing from the circular or other shaped mouthpiece the section of which is
intended to correspond with the desired dimensions and shape of the stream or
column of dough as it issues from the machine.
In order to adapt the apparatus to various kinds of dough or like material the
mouthpiece may be suitably formed of smooth metal or be provided with a lining
of any desirable material such as felt covered by thin stretched leather and a
funnel may be fitted in the mouthpiece through which water, lubricant or other
liquid may pass to the felt and be evenly distributed to the leather so as to prevent
adhesion of the dough. In front of the mouthpiece is an endless band passing over
rollers in a frame.
Within the casing before described are right and left handed screws mounted on
spindles and converging towards the smaller end thereof; the spindles are mounted
in bearings and on the plate forming one end of the casing and being in one piece
with the foundation plate.
The spindles are connected by toothed wheels gearing into one another one of them
carrying a toothed wheel engaging with a pinion on the driving gear which may be
operated by power or hand.
The rotation of the screws subjects the dough or material introduced into the
feed opening to a vigorous kneading action and gradually forces the dough or
material towards the mouthpiece through it issues assuming the shape thereof.
If desired the dough may be passed a second time through the machine.
On finally issuing from the machine the dough or substance is cut into lengths or
portions as desired.

Apparatus for Kneading Dough and the like.
I WILLIAM WILLOTT POPPLEWELL of the firm of Popplewell & Co. of 17 & 18
Southampton Buildings in the County of Middlesex Patent Agent do hereby declare
the nature of this invention (communicated to me from abroad by Johan Frederik
Schroeder of Angade 32 Copenhagen in the Kingdom of Denmark Manufacturer)
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :—
The object of my invention is to provide a machine for kneading dough or the like
for bread making on a large scale.

page_text: Referring to the accompanying drawings and to the figures and letters of reference
marked thereon
Figure 1 is a sectional elevation of my improved machine.
Figure 2 is a plan of the same.
Figure 3 shews the position of the worms f¹, f.
Figure 4 is an enlarged section of the mouthpiece through which the kneaded
dough is ejected.
The height of the casing a is uniform throughout, in width however it is tapering
and at the widest part is fitted with a feed hopper 7. At the narrow end there
is an intermediary piece which forms the connection from the almost elliptical
shape of the casing into the circular shape of the mouthpiece d. The cross section
of the latter corresponds with the dimensions which the dough is to receive on
issning from the machine.
For coarse dough that is not very "esive the mouthpiece may consist of smooth
metal bored out.
If the dough is finer and more adhesive the mouthpiece is provided with a lining
of say felt (see Figure 4) over which a thin leather is stretched. Into an aperture
on the upper part of the mouthpiece a funnel is then inserted through which water
or other liquid (say oil) passes to the lining of felt so that the latter evenly dis-
tributes the liquid absorbed by it to the leather thereby preventing adhesion of the
dough. In front of the mouthpiece an endless band is provided passing over the
rollers n in the frame O.
Within the casing a are two screws ff one right handed and the other left
handed. These screws are mounted on the spindles 91 92 converging towards the
smaller end of the casing. The spindles are mounted in hearings ¹¹ and b³, k³ on
the plate which forms one end of the casing and is in one piece with the
foundation plate. The spindles are connected by toothed wheels which gear with
one another; the spindle 9² carrying another toothed wheel also engaging with a
pinion on the driving gear
h.
The spindle of the driving gear is fitted with a pulley i.
When the screws f f¹ rotate the dough introduced by the feed opening bis
subjected to a vigorous kneading action and is also gradually forced towards the
mouthpiece whence it is forced out and assumes the shape of the section of such
mouthpiece. The dough being pushed upon the endless band m is cut off in pieces
of suitable size and if necessary again kneaded in the machine.
The machine may if desired be arranged for kneading and suitably shaping any
dough-like material by suitablying nodifying the size of the machine the shape
and pitch of the spirals the aperture or apertures of the mouthpiece. In small
machines for domestic purposes the belt gear may be removed and a hand crank
substituted.
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 :-
:-
First In machines for shaping dough or the like the arrangement of two or
more screws alternately engaging with one another and having their axes converging
towards a mouthpiece such as d and rotating in opposite directions for the purpose of
thoroughly kneading dough or like materials and forcing the said dough or the like
towards a mouthpiece so that it may be shaped by the latter substantially as described.
Second-In kneading or shaping machines with the arrangement indicated in
claim 1 a mouthpiece such as d lined with felt and leather or similar materials and
fitted with a moistening funnel substantially as herein described and illustrated in the
accompanying drawings.
