PROVISIONAL SPECIFICATION.
Improvements in Mechanism for Mixing Batter for the Production of
Sponge-cakes or the like, or for Mixing other Plastic or Liquid
Substances.
I, JOHN HUNT, of Baldwin Street Works, Bolton, in the County of Lancaster,
Engineer and Machinist, do hereby declare the nature of this invention to be as
follows, that is to say;-
-
It relates firstly to improvements in the construction of the bearings for the
rotary beaters in mechanism used in the mixing of batter for the production of
sponge-cakes or the like, or for mixing other plastic or liquid substances, whereby
said bearings are rendered firmer and more secure than they have been heretofore.
In carrying this part of my invention into effect I form the framework within
which the beaters rotate so that its ends for contact with of the vessel in which
the beaters are mounted to rotate will fit within suitably shaped bearings secured
to said walls, such bearings being so constructed that they will hold the frame-
work against rotation but will permit same to be readily detached when desired,
the usual, pivotal screw being employed for securing and retaining said framework
when in its operating position.
The stationery part of the beaters is secured by its bearing at one side enter-
ing a square or other shaped opening which will prevent rotation, while the hub
cf one of the beaters is made to rotate upon this bearing in this manner and by
the other parts of the beaters being constructed as heretofore perfect freedom is
allowed them for rotation and no part is pressed to produce excessive friction
against another.
The method of construction above described may be followed in the production
of any of the well known forms of beating or mixing mechanisms whether same
is of cylindrical, or partly cylindrical and other shape or whether same has
duplex or simple beaters, provided framework is employed for retaining such
beaters as described.
The second part of my invention relates to means whereby those mixing devices
which require keeping at a considerable temperature may be so kept and yet
the means employed afford every facility for cleanliness and being kept dry to
prevent corrosion and undue wear.
To attain this object, when hot water or other liquid is the means for main-
taining said temperature, I make the vessel for containing said liquid or water
entirely separate from the other mechanism, while I further form this latter so
that the lower extremities of its vessel's walls will take over and entirely sur-
round the vessel containing the water, thus freedom is afforded for access to this
Equid containing vessel and all taps, valves and funnels are discarded.
In place of the vessel above described being used, I may have a coil of piping
arranged beneath the mixing vessel so that facilities for the circulation of hot

page_text: water or steam for heating purposes may be made use of. Or again instead of
this coiled pipe I may have gas jets burning beneath the vessel or in proximity
therewith.

Improvements in Mechanism for Mixing Batter for the Production of
Sponge-cakes or the like, or for Mixing other Plastic or Liquid
Substances.
I, JOHN HUNT, of Baldwin Street Works, Bolton, in the County of Lancaster,
Engineer and Machinist, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statemenent, that is to say:-
It relates firstly to improvements in the construction of the bearings for the
rotary beaters in mechanism used for the mixing of batter for the production of
sponge-cakes or the like, or for mixing other plastic or liquid substances, whereby
said bearings are rendered firmer and more secure than they have been heretofore.
The second part of my invention relates to means whereby the mixing devices
which require keeping at a considerable temperature may be so kept and yet
the means employed afford every facility for cleanliness and being kept dry to
prevent corrosion and undue wear.
In the accompanying sheets of drawings which are illustrative of my
invention:
Fig. 1 is an elevation of apparatus, for mixing batter and the like, to which
my invention is applicable.
.
Fig. 2 is a plan of the parts shown by Fig. 1 but with the cover removed.
Fig. 3 is a part sectional elevation of the apparatus shown by Figs. 1 and 2.
Fig. 4 is a drawing in detail (enlarged scale) illustrating the formation or con-
struction of the bearings hereinafter described.
Fig. 5 is a view of the parts shown by Fig. 4 as seen from above.
In carrying the first part of my invention into effect I form the framework a
within which the beaters be rotate so that its ends for contact with the
walls of the vessel d in which they are mounted will fit within the flanged or
suitably shaped bearings f g secured to said walls, such bearings fg being so
constructed that they will hold the framework a against rotation but will permit
it to be readily withdrawn therefrom in a vertical direction when the binding
screw is removed from securing it.
The stationary part of the beaters is secured by its bearings at entering
a square opening made in the framework a which thus prevents its rotation while
the other end is supported by the shaft 1 of the beaters be which freely
rotates within it.
upon which
so that
The fixed bearings afford support for the hub of the beater
it is free to rotate while its other hub 63 is fixed firmly upon the shaft
the rotary motion of said shaft will be transmitted to the beater b.
Again the fixed bearings k¹ form the bearing for the shaft b¹ the end
which takes into it, its other end 15 rotating within and being supported by the
bearings a while the beaters care secured to the hubs ce rigidly fixed upon
the shaft b¹.
of

page_text: A slot is made in the end 6 of the shaft b₁ so that it may span the projecting
end of the driving spindle m as is well understood, said spindle m being rotated
by the handlen (or in place of this driving pulleys operated by a strap or driving
belt may be employed) through the gear wheels n'm¹.
By following the method of construction of the several parts as above described,
each moving part is allowed to freely operate without being unduly pressed
against its neighbouring part thus the engendering of excessive friction is
avoided.
Although I have only illustrated one form or class of beaters in the accom-
panying sheets of drawings, I wish it to be understood that my invention may be
followed in the production of many of the other well-known forms of beating or
mixing mechanism whether same is of the cylindrical shape as illustrated or of
partly cylindrical and other shapes or whether same has duplex or single beaters
provided framework is employed for retaining such beaters as hereinbefore
described.
To attain the object of the second part of my invention, when hot water or other
liquid is the means for maintaining the temperature of the vessel d I make the
vessels for containing said hot liquid or water entirely separate from the vessel d,
while I further form the said vessel d so that the lower extremities d' of its
walls will take over and entirely surround the vessels thus freedom is afforded
for access to this liquid containing vessels and all taps, valves, funnels or other
dirt harbouring devices are discarded.
In place of the vessels I may have a coil of piping (shown in broken lines
Fig. 1) arranged beneath the vessel d so that facilities for the circulation of hot
water or steam for heating purposes may be made use of. Or again instead of
this coiled pipe I may have gas jets burning beneath the vessel d or in proximity
with it.
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. In mixing machines of the class described, bearings for the beaters the same
being formed and constructed to operate substantially as herein specified.
2. In machines of the class described, beaters and bearings upon which they are
mounted, the same being formed, constructed and arranged to operate substan-
tially as set forth and as illustrated by the drawings.
3. In machines of the class described, devices for maintaining certain of the
parts at a desired increased temperature substantially as herein described.
Dated this 6th day of January 1900.
