We, THOMAS VICARS the Elder, JOHN VICARS the Elder, THOMAS VICARS the
Younger and JOHN VICARS the younger all of 29 Seel Street, Liverpool, in the
county of Lancaster Engineers do hereby declare the nature of the said invention
" to be as
for "IMPROVEMENTS IN DOUGH MIXING OR KNEADING MACHINES
follows:-
The object is to provide a simple durable and efficient machine for mixing or
kneading in the manufacture of bread biscuits, and confectionery.
A machine under our invention consists essentially in the combination of a
movable container or vessel with stirrers mixers or kneaders capable of being
rotated on vertical axes and of being lowered into and raised out of the vessel or
container.
"
A machine under our invention is with advantage constructed as follows;-The
receptacle or container is elliptical in horizontal section, has vertical sides and flat
bottom, and is mounted on wheels. A frame consisting of uprights and cross ties
is provided to carry the stirrers, mixers or kneaders. The stirrers mixers, or
kneaders are mounted on vertical spindles carried in bearings in the said frame,
and toothed, frictional, belt or other gear is provided whereby rotary and end
motion may be given to the said spindles.
The action of the machine is as follows:-The container or vessel is filled with
the materials or ingredients to be mixed or kneaded, the said container or vessel is
run beneath the stirrers, mixers, or kneaders which are then caused to rotate and
are lowered into the materials or ingredients to be mixed, or kneaded. When the
mixing or kneading is completed the stirrers mixers, or kneaders are raised and the
container or vessel is removed and replaced by a fresh one.
We prefer that the stirrers, mixers, or kneaders should be two in number and
that they should consist of radial screw arms, each arm having reversed helical
faces.

We THOMAS VICARS the Elder JOHN VICARS the Elder, THOMAS VICARS the
Younger and JOHN VICARS the Younger, all of 29 Seel Street Liverpool in the
County of Lancaster Engineers, do hereby declare the nature of this invention
and in what manner the saine is to be performed, to be particularly described
and ascertained in and by the following statement :—
The object is to provide a simple, durable and efficient machine for mixing or
kneading in the manufacture of bread biscuits and confectionery.
A Machine under our invention consists essentially in the combination of a
movable container or vessel with stirrers mixers or kneaders capable of being
rotated on vertical axes and of being lowered into and raised out of the vessel or
container.
A Machine under our invention is with advantage constructed as follows:-The
receptacle or container is elliptical in horizontal section, has vertical sides and flat
bottom, and is mounted on wheels. A frame consisting of uprights and cross ties
is provided to carry the stirrers mixers or kneaders. Tho stirrers mixers or
kneaders are mounted on vertical spindles carried in bearings in the said frame,
and toothed, frictional, belt or other gear is provided whereby rotary and end
motion may be given to the said spindles.
DESCRIPTION OF THE DRAWINGS.
Figs. 1 and 2 are elevations at right angles, and fig. 3 a plan of an improved
dough mixer or kneader under our invention. a is the receptacle or container
mounted on wheels b which run on lines c, d frame, e f bearings which carry the
spindles g on which are mounted the stirrers h, i skew bevel gear for giving
rotary motion to the spindles g. The said spindles have key ways in which
keys on the gear are free to slide so that end motion may be given to the spindles.
The bearings e are carried on a cross bar which is free to be moved up and down
the guides on the frame d by means of the worm gear and toothed wheels m
which take into racks on the guides k.

The action is as follows:-The container or vessel a is filled with the materials
or ingredients to be mixed or kneaded. The said container is run beneath the
stirrers h which are raised to their full height. The stirrers h are then caused to
rotate by the skew gear i and are lowered into the dough or materials or
ingredients to be mixed or kneaded by means of the screw gear 1. When the
stirring mixing or kneading is completed the stirrers h are raised by the gear l and
the container or vessel a is removed and another one put in its place.
Figs. 4. 5. and 6 show three ways in addition to the skew bevel gear shown in
figs. 1. 2 and 3 by which rotary motion may be conveniently given to the
spindles g. In fig. 4 a central pinion actuated by bevel gear gives motion to two
spur wheels one on each spindle. In fig. 5 a pinion and spur wheel give motion
to bevel gear. In fig. 6 worm gear is used,

page_text: Fig. 7 is a view showing pinion gear instead of worm gear for giving end motion
to the spindles.
Figs. 8 and 9 show nut and screw instead of rack gear for raising and lowering
the bar j and spindles g. In fig. 8 the nuts are fixed on the barj and the screws
are caused to rotate. In fig. 9 the screws remain stationary and the nuts are
caused to rotate.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, we declare that what
we claim is
First. Dough mixing or kneading machines constructed substantially as setforth.
Second. The combination of movable vessels or containers with mixing or
kneading appliances substantially as setforth.
Third. In combination with movable vessels or containers mixers kneaders or
stirrers mounted and actuated substantially as setforth.
