PROVISIONAL SPECIFICATION.
Improvements in Dough Mixers or Kneaders.
We JOHN VICARS, THOMAS VICARS, and JOHN VICARS the Younger, all of
56 Seel Street, Liverpool, in the County of Lancaster, Engineers, do hereby
declare the nature of this invention to be as follows:-
The invention relates to apparatus for mixing or kneading dough in which arms
on a horizontal shaft rotate within a drum. The main objects are to prevent
accumulation of stale dough within the drum and entablature or upper framework,
and to facilitate cleansing, and to improve the construction generally.
Apparatus under our invention consists essentially of improved forms of liquid
and flour containers carried by an improved crosshead secured to the upright frame
of the machine; the crosshead being so made as to form a hopper, through which
the materials to be mixed are fed to the drum. The said crosshead is fitted with a
door through which it can be easily cleaned.
The arm carrying shaft is cylindrical and the arms screw shaped or otherwise are
made with bosses arranged to cover the whole of the shaft, with keys or like locking
devices, and arc set one in advance of the other.
The said shaft is actuated by spur or belt gear in the usual manner.

Improvements in Dough Mixers or Kneaders.
We JOHN VICARS, THOMAS VICARS, and JOHN VICARS the Younger, all of
56 Seel Street Liverpool, in the County of Lancaster, 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:---

page_text: of the drum slightly excentric therewith, so that when the drum mouth is in an
upward direction a tight joint is made and there is the minimum of space above the
drum for the accumulation of stale dough..
The excentric formation of the lower face of the entablature or crosshead enables
the drum to be readily turned with the mouth downwards for discharging the
contents. The said entablature or crosshead is also made with central ways or
hoppers e, f, through which flour or solid materials, and water or liquid matter are
respectively fed to the drum and with a door through which the flour hopper may
g
be readily cleansed. is the flour or solid material container secured to the
entablature or crosshead immediately above the way e and provided with a movable
floor i secured to a crossbar; passing through bearings in the sides of the container.
k is a catch piece for holding the floor in position. is a handle for operating the
catch piece and m a handle for raising the floor. n represents one of several
novable pieces for varying the depth of the container above the floor so as to enable
the requisite quantities of solid material required to be accurately gauged. o is the
liquid container carried by the entablature or-crosshead d, and connected to the
hopper way by means of a pipe p. 9 is a tap for regulating the liquid supply.
is the shaft carrying the dough mixing arms, passing through the trunnions c and
fitted with pulley or other driving gear s. t mixing arms made with bosses u which
cover the whole of the shaft so as to prevent accumulation of dough and facilitate
cleaning. The said arms are set one in advance of the other and are secured in
position on the shaft by means of keys or other suitable locking devices. The
drum bis shown partly turned round in Fig. 2 so as to allow the shaft and arms to
be seen.
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 :-
First. In dough mixers or kneaders the combination of a mixing drum and
entablature or crosshead, substantially as and for the purpose set forth.
Second. Crossheads for dough mixers or kneaders with solid and liquid material
hoppers, substantially as and for the purpose set forth.
Third. In dough mixers or kneaders containers for solid and liquid materials
constructed and combined with a crosshead having hoppers substantially as set
forth.
Fourth. Dough mixers or kneaders constructed substantially as and for the :
purpose set forth.
