PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Butter, and Apparatus therefor.
I, WILLIAM HAFFENDEN SELFE LEONARD, of The Achers, Rodborough,
near Stroud, in the County of Gloucester, Gentleman, do hereby declare the
nature of this invention to be as follows :-
This invention relates to improvements in the manufacture of butter and
apparatus therefor whereby milk or cream can be converted into butter in a much
shorter space of time than hitherto, and this is effected by drawing air through the
milk or cream in the manner hereinafter described.
In carrying out my invention I employ a frame adapted to be placed in
juxtaposition with an open tub or vessel for containing the milk or cream to be
treated and provided with suitable bearings for carrying within the tub a hollow
spindle on which is mounted a disc the underside of which is hollowed out and the
rim or periphery so formed is provided with a number of openings. The spindle
is provided with means such as an adjustable pulley whereby the position of the
disc in the bucket can be varied. To the inner surface of the tub are attached a
number of removable breaks, the said breaks consisting of strips of wood provided
with wire hooks by which they are suspended from the edge of the tub. The
spindle can be driven from a wheel mounted in the frame by a band passing over
guide pulleys but any other suitable means may be employed.
The operation is as follows:-On the spindle being rotated, the outer end being
open to the atmosphere, air is drawn through the hollow spindle and through the
milk or cream with the result that the said milk or cream is formed into butter
with great rapidity.
The tub is advantageously provided with a plug or cock at its lower part so that
when the churning operation is completed the butter milk can be run off: water
can then be poured into the tub and the spindle revolved to wash the butter, and
the water being drawn off the butter is ready for packing.

COMTELE DI ECIFICATIVA
Improvements in the Manufacture of Butter, and Apparatus therefor.
I, WILLIAM HAFFENDEN SELFE LEONARD, of The Achers, Rodborough,
near Stroud, in the County of Gloucester, 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 improvements in the manufacture of butter and
apparatus therefor whereby milk or cream can be converted into butter in a much
shorter space of time than hitherto, and this is effected by drawing air through the
milk or cream in the manner hereinafter described.
In carrying out my invention I employ a frame and an open tub or vessel for
containing the milk or cream to be treated adapted to be placed in juxtaposition,
the said frame being provided with suitable bearings for carrying within the tub

page_text: a hollow spindle on which is mounted a disc having the underside hollowed out and the
rim or periphery formed with a number of openings. The spindle is provided with
means such as an adjustable pulley whereby the position of the disc in the bucket
can be varied. To the inner surface of the tub are attached a number of removable
breaks or breaker-boards consisting of strips of wood provided with wire-hooks by
which they are suspended from the edge of the tub. The spindle can be driven
from a wheel mounted in the frame by a band passing over guide-pulleys but any
other suitable means may be employed.
To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawings, in which :-
:-
Figure 1 is a sectional elevation of apparatus constructed according to my
invention:
Figure 2 is a plan of the churning vessel; and,
Figure 3 is an underside view of the disc drawn to an enlarged scale.
a is the open tub forming the churning vessel, and 6 is the juxtaposed frame, the
said frame having the bar c extending over the centre of the tub and carrying a
hollow spindle d'in suitable bearings.
e is the churning disc having the underside hollowed out as clearly shewn in
Figure 3 and provided with openings f, in the rim or periphery the said disc being
attached to the hollow spindle d. These openings are arranged in a somewhat
tangential direction so that when the said disc is rotated in the direction of the
arrow, Figure 3, the tendency will be to form a vacuum in the hollow underside
of the disc thereby drawing air down through the hollow tube.
g is a pulley on the hollow spindle d, and is a driving pulley around which and
around the pulley g a rope or band i passes. The pulley g is so arranged upon the
spindle d that the said spindle cau be raised or lowered relatively with the pulley.
jjare the removable breaker-boards each of which is provided with a spring-clip
such as k to permit of it being readily applied to and removed from the walls of
the tub.
The operation of the apparatus is as follows:-
On the spindle being rotated, the milk or cream is agitated and air is drawn
down through the hollow spindle and under the centrifugal action imparted to it
by the rotation of the disc is distributed through the milk or cream in the tub with
the result that the said milk or cream is rapidly formed into butter.
The tub is advantageously provided with a plug or with a cock at its lower
part so that when the churning operation is completed the butter-milk can be run
off; water can then be poured into the tub and the disc again revolved to wash
the butter which, when the water has been drawn off, is ready to be made up.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, 1 declare that what 1
claim is :-
1. The improvements in the manufacture of butter consisting in agitating the
milk or cream by means of a churning disc and at the same time distributing air
through the milk or cream, the said air passing through openings in the churning
disc, substantially as described.
2. Apparatus for manufacturing butter wherein a churning disc hollowed out ou
its underside.and provided with openings is employed, the disc being mounted upon
a hollow spindle, substantially as, and for the purpose, described.
3. The manufacture and use of the improved apparatus for making butter
herein before described and illustrated in the accompanying drawing.
