PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Kneading Dough and Shaping it
into Loaves.
A communication from JULIUS MULLER, of Ehrenberg, near Hohnstein, Saxony,
in the Empire of Germany, Miller.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
M.I.M.E., do hereby declare the nature of this invention to be as follows :-
--
It is a well-known fact that in making bread considerable time is lost in forming
or shaping the dough into loaves, the services of a special workman being in most
cases requisite for the purpose.
The object of this invention is to provide means for performing this part of the
baker's work by machinery and in a very short time.
The invention consists of a cylindrical trough or receptacle, open and surmounted
on one side by a hopper and provided with a door or equivalent at one end and
internally with a rotating fork the arms of which have surfaces representing parts
of convolutions of a steep-pitched screw. This fork is adapted to engage the
dough fed through the hopper and to knead it thoroughly and spin it out as it were
into a long roll which comes out of the cylinder through its open end. At or
near this opening of the cylinder a knife connected with the door is arranged to
be reciprocated periodically either by hand or by machinery, so that as soon as a
piece of dough sufficient to form a loaf has issued from the trough it is cut off by
the said knife. The cylinder or trough is then closed by the sliding lid, and while
it remains closed the machine may knead a fresh supply of dough. Each section
thus severed from the roll of dough has practically the shape of a loaf and only
requires being rounded off at the corners or pressed into a suitable mould. One
of the chief advantages of the machine is that while forming the dough into a
continuous roll as stated, it also increases and equalizes its compactness through
the additional kneading operation it performs. By means of this machine one
operative may readily carry out the whole process of preparing the loaves for the
oven from the initial stage in which the dough is first prepared and kneaded, up
to the last or baking stage.
To facilitate the cleaning of the apparatus it is made divisible along a central
longitudinal line, both sections being hinged together at one side and fixed with
screws on the other side.
Provision may be made for the operative to be able to ascertain by sight or
hearing when the machine has performed a certain number of revolutions
corresponding to a given length of the dough-roll so that he may see that the
sliding door is shut in time.

A communication from JULIUS MÜLLER, of Ehrenberg, near Hohnstein, Saxony,
in the Empire of Germany, Miller.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
Member of the Institution of Mechanical Engineers, 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 :-
It is a well-known fact that in making bread considerable time is lost in forming
or shaping the dough into loaves, the services of a special workman being in most
cases requisite for the purpose.
The object of this invention is to provide means for performing this part of the
baker's work by machinery and in a very short time.
The invention consists of a cylindrical trough or receptacle, open and surmounted
on one side by a hopper and provided with a door or equivalent at one end and
internally with a rotating fork the arms of which have surfaces representing parts
of convolutions of a steep-pitched screw. This fork is adapted to engage the
dough fed through the hopper and to knead it thoroughly and spin it out, as it
were, into a long roll which comes out of the cylinder through its open end. At or
near this opening of the cylinder a knife connected with or forming part of the door
is arranged to be reciprocated periodically either by hand or by machinery so that
as soon as a piece of dough sufficient to form a loaf has issued from the trough, it is
cut off by the said knife. The cylinder or trough is then closed by the sliding lid,
and while it remains closed the machine may knead a fresh supply of dough. Each
section thus severed from the roll of dough has practically the shape of a loaf and
only requires being rounded off at the corners or pressed into a suitable mould. One
of the chief advantages of the machine is that, while forming the dough into a
continuous roll, as stated, it also increases and equalizes its compactness through the
additional kneading operation it performs. By means of this machine one operative
may readily carry out the whole process of preparing the loaves for the oven from
the initial stage, in which the dough is first prepared and kneaded, up to the last or
baking stage.

In the accompanying drawings:-
Figure 1 is an end elevation and
Figure 2 a longitudinal section of the machine.
a is the cylindrical receptacle or trough, closed at b, but open at c. A. hopper dis
preferably cast in one piece with the said trough, and surmounted by a plate or tray e
upon which a provision batch or charge of dough may be placed. To facilitate the
cleaning of the apparatus it is made divisible along a central longitudinal line, both
sections being hinged together at one side and fixed with screws on the other side.
The fork or mixer consists of a stock or cross-head mounted on the driving
shaft g,
and two arms secured to the said cross-head whose surfaces represent parts
of convolutions of a steep-pitched screw, and which extend nearly throughout the
length of the cylinder a." The driving shaft 7 may be operated by hand, or by
power if available, as for example, where kneading machines are usually employed.
is the sliding lid or door, pivotted at i and adapted to be operated by means of
the handle, though, if preferred, it may be connected to and disconnected from
the source of motive power by suitable mechanism, so as to open and shut the slide
or door at predetermined intervals of time. The lower edge of the door may
be sharpened as at h¹ so as to serve as the knife by which the dough is cut into
pieces for forming loaves. Provision may be made for the operative to be able
to ascertain by sight or hearing when the machine has performed a certain number

page_text: of revolutions corresponding to a given length of the dough-roll so that he may
see that the door h is shut in time.
Having now particularly described and ascertained the nature of the said inven-
tion and in what mauner the same is to be performed as communicated to me by
my foreign correspondent I declare that what I claim is :-
A. machine for shaping loaves in which the dough is fed to a hopper such as d
and thence passes into a cylindrical receptacle such as a open at one end and in
which it is kneaded or worked by a slowly rotating fork-shaped agitator such as f
the prongs or arms of which take the form of a screw-thread of long pitch whereby
the dough is formed into a roll issuing from the open end of the receptacle and as
it does so is cut up into sections or loaves by a sliding cutter substantially as
described and illustrated in the accompanying drawings.
