Improved Whisking and Mixing Machine.
THOMAS ROBERT WAITE 11 Eagle Street South Heigham Norwich do hereby
declare the nature of this invention to be as follows:
I fix a bowl inside a hot water chamber under the bowl are fixed cog wheels
working a socket and spindle through the centre of the bowl inside the bowl are fixed
arms and mixers which revolve round contrary to each other.
My invention relates to the movement underneath the bowl causing double action
through the centre.

Improved whisking and mixing macnine.
I THOMAS ROBERT WAITE late of 11 Eagle Street South Heigham but now of
4 Rose Lane in the City of Norwich Tin Plate Worker 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 relates to whisking and mixing machines and consists of a bowl fixed
inside a cylinder with a hot water or steam chamber underneath. Through the centre
of the bowl projects a spindle to which is attached mixers or beaters revolving round
the inside of the bowl in reverse rotation; the action of the mixers being regulated
by mechanism working underneath the bowl and contained in the lower half of the
cylinder. The object of the invention is to provide a simpler, less expensive and more
effective whisking and mixing machine than now exists.
To enable my invention to be fully understood I describe the same with reference
to the accompanying drawing which is an elevation, partly in section. I construct a
cylindrical body A. B. C. D from tin or other suitable material with a horizontal
division E. F in the middle. I insert a bowl G. G. in the top end of this body which
I solder or fasten to it. The space between the bowl bottom and the upper division
of the body forms a chamber capable of holding hot water or steam which can be
poured or injected through an inlet H on the top side secured by a screw cap I and
drawn out from an ordinary tap J in the inside of the body. A hole is drilled
through the bottom of the bowl and the middle division of the body in which is
soldered or fixed a bush or brass cylinder K. The bottom of the body is affixed to
an iron casting or framework L. Projecting from one side of the body is a handle M
to control the interior mechanism. The handle is connected to a horizontal
spindle N running through bearings O in the frame to a bevel gear wheel P the
wheel being secured to the spindle N by a pin or key Q. This wheel P gears into
an upper and a lower pinion. The lower spindle R is fixed at the bottom of a
vertical spindle or shaft $ rising from the centre of the frame L. The upper pinion T
is made with a long boss U squared at the top in order to drive the lower agitator V
within the bowl G and revolves loosely on the shaft or vertical spindle S. The
vertical spindle S is thus made to protrude through the bush K in the centre of the

page_text: bowl G sufficiently to allow the lower agitator V to be fixed upon the squared boss U
of the upper pinion T and for the upper agitator W to be screwed to a left hand
thread Z cut into the top of the vertical spindle S for the purpose. This causes the
two agitators to rotate in reverse directions when the handle is turned. The agitators
are in two distinct and separate parts and can be made from almost any metal. The
lower agitator V is shaped like a semicircular fork with its tines protruding upwards.
The upper agitator W is shaped like the head of an ordinary rake with the tines
bending downwards. Both agitators have an even number of tines which are made
to pass between each other during their reverse rotation. The tines are pared on the
sides facing the direction of rotation and are bent slightly inward. They are made
considerably thicker at the base than at the point. The lower part of the central
stem of the upper agitator X. W is moulded cut or fashioned after the style of a
coarse pitched screw. The object of this peculiar shape of the agitators is to cause
the materials during the process of mixing to converge to the centre of the bowl
where they can the better be manipulated.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I claim :-
1. An improved whisking and mixing machine constructed or operating sub-
stantially as described with reference to the the accompanying drawings.
2. A mixing and whisking machine having double agitators with reverse action
working from the centre of the bowl with driving power underneath.
