This invention for improvements in or connected with mixing of substances
has for its object to provide means for thoroughly mixing flour and water or
liquor to form dough without any hand labour or "mechanical treatment, but
the apparatus is also suitable for mixing other substances.
In carrying out this invention as applied to the making of dough, a con-
tinuously delivering rotating sieve is mounted above a receiving receptacle and
is supplied with the flour to be mixed. At the top of the receptacle and just
below the rotating sieve is a water spray or distributing apparatus that dis-
tributes the water or liquor evenly exactly as the flour is distributed. In falling
down the receptacle the flour and water become intimately mixed and form an
even and homogeneous dough at the bottom.

I, DAVID WILLIAM WALL, Baker, of 56, Brixton Road,, S.W., in the County
of London, 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 for improvements in or connected with the mixing of substances
has for its object to provide means for thoroughly mixing flour and water or
liquor to form dough without any hand labour or mechanical treatment, but
the apparatus is also suitable for mixing other substances.
In carrying out this invention as applied to the making of dough, a continuously
delivering sieve is mounted above a receiving receptacle and is supplied with
the flour to be mixed. At the top of the receptacle and just below the rotating
sieve is a water spray or distributing apparatus that distributes the water or
liquor evenly exactly as the flour is distributed. In falling down into the
receptacle the flour and water become intimately mixed and form an even and
homogenous dough at the bottom.
The accompanying drawing shows in sectional elevation an apparatus suit-
able for mixing or making dough according to this invention.

page_text: A cylindrical vessel a provided with a perforated or meshed bottom 6 to form
a sieve is mounted on a cylindrical casing and support c and supplied, through a
hopper d, with flour to be mixed. The meshes of the sieve are kept open and
the flour uniformly distributed thereon by means of rotary brushes e mounted on
a vertical shaft f working in bearings 9 and being driven from the pulley h
through the shaft i and suitable bevel wheels 1.m as shown.
Beneath the sieve is a series of radiating pipes n connected to a water reser-
voir o and finely perforated on their under surfaces so that when the reservoir o
is charged a cloud of spray is emitted so long as the liquid supply is main-
tained and falls into the cylindrical receptacle.
The receptacle p rests upon a table plate q mounted on a shaft r working in
bearings s and is rotated from the pulley h through the bevel wheels tv shaft w
and spur wheels y as shown.
The hopper & and reservoir o having been charged with flour and the proper
liquid respectively in suitable proportions and the brushes e and receptacle 2 set
rotating through the driving pulley h the flour passes through the sieve in a
cloudy mass and is met by a stream of finely divided spray issuing from the
perforated pipes the whole being thus thoroughly mixed together and falling
into the receptacle 2 in the form of dough.
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. A method of mixing substances such as flour and liquid to form dough
consisting in passing the flour through a sieve so as to deliver it in a state of
fine division or cloud and then acting on it with finely divided spray of suitable
liquid substantially as described.
2. In an apparatus for mixing substances' such as flour and liquid in the
manfacture of dough the combination of a sieve for containing the flour, brushes
rotating within the sieve, perforated pipes placed beneath the sieve and con-
nected to a reservoir, a rotating dough receptacle placed beneath the said sieve
and perforated pipes, and means for rotating the said brushes and dough receptacle.
3. An apparatus for mixing substances arranged and constructed substantially
as described and shown.
