PROVISIONAL SPECIFICATION.
An Improved Cake Mixer or Butter Batter Beater.
I, STEPHEN HUBBARD of 3, Kings Road St. Leonards on Sea Sussex, Gentleman, do
hereby declare the nature of this invention to be as follows:-
My Invention consists of a machine or apparatus especially suitable for mixing
butter batter or such like, containing the necessary ingredients which have to be
thoroughly incorporated and properly admixed together for cake making, such as
Maderias, buns, and other esculent or edible fancy goods or articles.
I provide a circular vessel of metal (of iron by preference and galvanised) or other
material, having a cast iron tripod frame which may be clamped to the iron rim of
the circular vessel or container, and within the centre of which a vertical spindle is
securely held or supported in position at the upper portion of the circular vessel
and rim or cover, and the lower part of the said vertical spindle is connected an
inverted circular form or frame (in which it bears or is stepped). Upon the upper
portion of the spindle just within the top of the circular vessel or container-a
horizontal radial plate is fixed and a series of vertical bars are fitted and connected
to the lower inverted circular frame which is just clear of the diameter of the circular
vessel or container and a further series of vertical bars are fixed to the lower inverted
frame and project to a suitable distance upwards, and suitably spaced as between the
vertical bars which are held in position from the horizontal radial plate and secured
to the inverted circular frame within the circular vessel or container.
The vertical downward blades or cutters as well as the upper blades or cutters I
peculiarly form and arrange according to my Invention so that in section they may be
tapered from the inner and outer edges or sides to an angle of about 60 degrees or
thereabouts, as found most suitable in certain cases but they may in both cases
be of a different oblique form, or of an acute angle or of an oval form or other
section.
If wished a difference or variation may be made in the angle given to the vertical
blades or cutters fitted from the upper portion to those fixed within the lower inverted
curved frame.
The upper portion of the vertical spindle is provided with a couple of bevil or
spur wheels having a larger wheel gearing into both, fixed upon a horizontal shaft
having its bearing in the upper cast iron frame and a driving wheel keyed on the
end of same which may be driven by hand or otherwise by which rotary motion is
given to the vertical spindle and the horizontal radial plate as well as the lower
inverted circular frame to which the blades or cutters are secured and by the peculiar
shape and form of the blades or cutters as proposed by me I am enabled when centri-
fugal action is given to beat up and thoroughly incorporate the mixture in manner
desired for the purpose.
The entire apparatus would be provided with a stout frame or casting forming part
of it so as to be firmly secured in position and provision given in the lower casing
of the circular vessel or container for any extra amount of water or moisture being
drained off by means of a tap.
As my improvements are capable of some modifications without departing from the
principle thereof I do not restrict myself to materials dimensions or the precise form
or placement of the parts thereof.

An Improved Cake Mixer or Butter Batter Beater.
I STEPHEN HUBBARD of 3 Kings Road. St. Leonards on Sea. Sussex Gentleman
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 an improved machine or apparatus for mixing butter batter
or similar compound containing the necessary ingrediants for making Maderia or other
cakes, buns, or such like edible fancy goods, or articles, and consists in the employ-
ment of circular vessel preferably constructed of galvanized iron, into which the
necessary ingrediants are placed, and stirred together to form the compound. This
vessel is constructed with a curved bottom provided with a recess or bearing which
supports the lower end of a vertical shaft or spindle passing centrally through the
vessel. To the top of the said vessel is clamped or fixed a cast iron tripod frame
forming a support or bearing for the upper end of the said shaft or spindle and carrying
bevil gear for rotating the same. A horizontal plate or bar is suspended from the
tripod frame just below the top edge of the circular vessel. This plate or bar is
provided with a series of vertical bars or knives descending nearly to the bottom of
the vessel and is furnished moreover, with a bevil wheel gearing into a larger bevil
wheel carried by the tripod frame and operated by a crank handle for hand labor.
When power is employed this crank handle is replaced by a pulley; motion is
thereby imparted to the said plate or bar with its knives all of which rotate within
the said vessel. To the lower end of the shaft or spindle is fixed an inverted circular
frame which is just clear of the bottom of the vessel and which is likewise provided
with vertical bars or knives arranged in such a manner that when the machine is
rotated the latter bars pass between the intervals seperating the bars or knives of the
upper radial bar. This inverted frame with its knives is likewise rotated by means of
a bevil wheel fixed to the upper part of the shaft or spindle gearing into the aforesaid
larger bevil wheel, so that the two sets of knives are rotated in different directions
and at the same speed within the vessel. These knives or blades are so constructed
that in section their inner and outer edges or sides are tapered to an angle of 60 degrees
or thereabout or they may be of an oval or other suitable section.
;
And in order that my invention may be more fully understood, I will describe the
same with reference to the accompanying sheet of drawings in which Fig. 1 is a
sectional elevation of my improved apparatus Fig. 2 is an elevation at right angles
thereto. Fig. 3 is a plan, and Fig. 4 is a plan of the circular frame and its knives
showing the knives of the upper radial bar in section a is the circular vessel provided
with a curved bottom a', bis the tripod frame clamped or fixed to the top of the
vessel a by means of curved strips or projections c, c', the strip c entering a slit
formed in a curved portion 61 of the tripod-frame and being secured thereto by a
pin d while the other arms of the tripod frame have projecting parts 62 which bear
against the lower parts of the strips c¹. Owing to this arrangement when the pin d
is withdrawn and the frame b turned partly round the latter, can be readily removed
e is the vertical shaft or spindle supported in a footstep bearing a² its upper end
revolving in a bearing 63 forming part of the frame b, f is a horizontal radial bar or plate
whose boss or journal 2 is carried by and is capable of revolving in the central
bearing of the frame bf1f1 etc. are the vertical bars or knives formed integrelly with
or fixed to the said plate f, g is a circular frame fixed to the lower end of the shaft e
just clear of the bottom a¹ and carrying vertical bars or knives g', placed interme
diately of the knives f¹. The bar or plate f is revolved by means of a bevil wheel h
fixed to the top of its journal or bearing part 2 which with the said wheel revolves
loosely around the shaft e and gears with a larger bevil wheel h¹ carried by a bearing
formed in a bracket i fixed to the frame b. The wheel h' is turned in the example
shown by a crank handle k and gears with another bevil wheel h² fixed to the upper

page_text: part of the shaft e so as to turn the said shaft and the circular frame g in a contrary
direction to that of the bar or plate f.
The cutting edges of the knives or bars g¹, f¹ are formed at an angle of 60 degrees
or thereabout as shewn in plan in Fig. 4. is a bar passing through holes formed
in the prolongations of the sides of the vessel a underneath the same this bar being
curved at one end, and provided with a screw clamp m while its other end passes
through the eye of a screw bolt n for the purpose of supporting and fixing the vessel
in any suitable position, o. is a chamber underneath the bottom of the vessel for
receiving any extra amount of water or moisture which is drained off by means of a
tap p.
As my improvements are capable of some modifications without departing from the
principle thereof I do not restrict myself to materials, dimensions, or the precise form
or placement of the parts thereof.
Having now fully 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 :-
Claim. The improved mixing and kneading machine arranged, constructed and
operating substantially as and for the purpose described and shown in the accompany-
ing drawings.
