PROVISIONAL SPECIFICATION.
Improvements in or relating to Machinery or Apparatus for Mixing
and Kneading Dough and other Substances.
We CHARLES HENRY HARDING of 23 Humberstone Gate and Clarence
Street, Leicester, Baker and Confectioner, and ALFRED HUNT. of 25 Humberstone
Road, Leicester, Bakers' Engineer do hereby declare the nature of this invention
to be as follows:-
This invention has reference to machinery or apparatus for mixing and kneading
dough and other substances.
According to our invention we employ a cylinder, barrel, or similar receptacle,
stationary or otherwise, to receive the ingredients to be mixed and kneaded,
Passing through this receptacle may be a shaft having a bearing in each end
thereof or otherwise, the said shaft being driven by any suitable gearing.
The said shaft may have attached thereto at intervals in its length suitably
shaped blades or equivalent adapted to move among the materials to be mixed
or kneaded and also arranged in such a manner as to conduct or traverse the
ingredients or dough from one part of the receptacle to another so that the
material being mixed or kneaded is brought under the action of first one blade
and then another.
We may if desired revolve the cylinder while the shaft and its attached blades
remain stationary.
A suitable door is formed in the cylinder for the insertion and removal of the
materials being treated.

Improvements in or relating to Machinery or Apparatus for Mixing
and Kneading Dough and other Substances.
We CHARLES HENRY HARDING of 23 Humberstone Gate and Clarence Strett
Leicester, Baker and Confectioner, and ALFRED HUNT of 25 Humberstone Road,
Leicester, Bakers' Engineer, 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 has reference to machinery or apparatus for mixing and kneading
dough and other substances.
According to our invention, we employ a cylinder, barrel or similar receptacle,
stationary or otherwise, to receive the ingredients to be mixed and kneaded.
Passing through this receptacle is a shaft having a bearing in each end thereof
or otherwise, the said shaft being driven by any suitable gearing.
The said shaft has attached thereto at intervals in its length suitably shape:1
blades or equivalent adapted to move among the materials to be mixed or kneaded
and also arranged in such a manner as to conduct or traverse the ingredients or

page_text: dough from one part of the receptacle to another, so that the material being mixed
or kneaded is brought under the action of first one blade and then the other.
We may if desired revolve the cylinder while the shaft and its attached blades
remain stationary.
A suitable door may if desired be formed in the cylinder for the insertion and
removal of the materials being treated..
The invention will be fully understood from the following further description in
reference to the accompanying drawings in which
Figure 1 is a side elevation and Figure 2 an end elevation of a mixing or
kneading machine constructed in accordance with.our invention.
Figure 3 is a longitudinal section through the mixing trough, and Figure 4 is an
end elevation thereof.
Figure 5 is a central transverse section of Fig..3.
Figures 6 to 10 are details hereinafter referred.to.
A represents a trough or receptacle in which is placed the materials to be mixed
or kneaded.
This trough may be of the shape shown or any other suitable shape and is
formed at each end with a trunnion A which rests in bearings B' in the side
standards B.
Passing through the centre of the trough is a shaft C resting in the trunnions A¹
and upon which is screwed a sleeve C¹ Figs. 5 and 8, having a spiral blade or
blades C formed integrally therewith as shown.
The said sleeve and blades are revolved with the shaft C and the blades constantly
move the ingredients from one part of the trough to the other in such a manner as
to mix or kneȧd them.
The said shaft receives its motion from a tooth wheel D Figs. 1 and 2 on the
end thereof gearing with a pinion (not shown) on the arbor E' Fig. 1. and immediately
behind the hand wheel F so as to gear with and impart motion to the said toothed
wheel D and shaft C.
The arbor E' is supported in a bracket projecting from the standard but not
shown in the drawing.
The hand wheel F is turned by a handle F1, or as is obvious, pulleys may be
placed upon the arbor El so as to drive the machine by power.
In order to admit of the shaft C and the blades thereon being placed within or
removed from the trough A each end of the latter is formed with a slot or
opening A as shown most clearly in Fig. 5, and when the said shaft and blades are
placed in their working positions, such openings are filled by movable portions A³
made to fit the same, the lower parts A of which are formed semi-circular in
section to fit over the shaft. C and thus form..a complete trunnion or bearing for
the said shaft.

To keep the said movable.end pieces A³ in their proper positions in the end of
the trough, we employ a latch G Fig. 4. which is pivotted at G¹ to the end of the
cylinder and presses tightly against a rib A5 on the said end pieces.
The free end of the latch rests in a catch plate G' Fig. 4. on the end of the
trough.
Passing over the lower part A' of the said end block there is a clamp plate H
shown most clearly in Fig. 6. which is perforated at each end to pass over two
screwed studs H¹ Fig. 4. rigidly connected to the bearings B' and the said clamp
plate is tightened in position by thumb nuts H2 Figs. 4, 6 and 7.
The materials to be mixed or kneaded are placed in the trough through the open
top and to remove the said mixed or kneaded ingredients, the trough may be
inverted so that the said ingredients may fail into any suitable receptacle placed
underneath to receive them.
To keep the trough steady and in its proper vertical position during the time
the machine is in operation a notched plate J, Figs. 2 & 4, is attached to the end
of the trough and into which is received the end of a latch J Fig. 1. pivotted at J2
to the standard B.

page_text: The invention is not limited to the use of a trough such as A as any convenient
shaped receptacle or mixing chamber may be used either open or closed, in the
latter case a suitable door may be provided through which the materials may be
placed within or removed from the mixing chamber.
The blades C2 are constructed of such a radius as to have only the slightest
practicable clearance of the side of the trough A thereby insuring that the whole
of the materials to be mixed or kneaded are brought within the action thereof.
The said blades may if desired be cast integrally with the shaft instead of with
the sleeve C¹.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
:-
1. In a mixing or kneading machine the combination of a trough or equivalent
chamber and a mixing blade or blades therein operating substantially as
described.
2. In a mixing or kneading machine the combination with a mixing chamber of
a shaft revolving therein and provided with one or more mixing blades constructed
and operating substantially in the manner described.
3. The improved mixing or kneading machine consisting of the parts constructed
arranged and operating substantially in the manner described and illustrated in the
accompanying drawings.
