Improvements in Apparatus for Churning Milk or for Mixing
Various Liquids or Materials.
I, ROBERT AUSTIN, of 18, Dixon Road, in the County of Glasgow, North Britain,
Laundry Engineer, do hereby declare the nature of this invention to be as follows,
that is to say: —
My said invention has for its object to improve the construction and action of
apparatus for churning milk or for mixing various liquids or materials.
In carrying out my invention I provide a box the middle part of which is
square or rectangular, whilst the ends are in the form of oblique pyramids each
with a side flush with the top of the box their extreme ends being diagonally
opposite. The box is provided with trunnions which extend out from each side
and work in bearings in a stand or framing and a handle is fitted to the box by
means of which a rocking or oscillating motion may be imparted to it. Access
to the interior may be provided for by one or more tight-fitting doors or covers at
any convenient part. In a preferable arrangement, portions of the top of the
box extending from near the middle where they are hinged to the ends are fitted
as doors.
A window may be fitted in the box or in the door or doors through
which the condition of the contents may be observed at any time. The inner
sides of the box are, by preference, made with ribs or corrugations which may
be of any suitable shape; and on the inside of the middle of the top of the box
I attach, by screws or otherwise so as to be easily removable a board or plate
carrying a number of blades or bars of any suitable shape in cross section.
When the box has been charged and released from its catch it can be rocked
on its trunnions the contents of the box passing from end to end whilst the par-
ticular shape of the ends of the box give a swirling motion or a motion from side
to side alternately to the contents which motion assisted by the corrugations and
the fixed blades effects the churning or mixing of the contents in a speedy and
satisfactory manner.
The rocking motion may be given by hand or by means of a connecting rod
from a rotating crank or equivalent. A weight may be arranged to be wound up
quickly on a barrel and whilst descending to give the rocking motion required
for a churning or mixing operation.
Dated this Thirteenth day of December. 1898.

Improvements in Apparatus for Churning Milk or for Mixing
Various Liquids or Materials.
I, ROBERT AUSTIN, of 18, Dixon Road, in the County of Glasgow, North Britain,
Laundry Engineer, do hereby declare the nature of this invention and in what
Price 8d1

page_text: manner the same is to be performed, to be particularly described and ascertained
in and by the following statement, that is to say: -
My said invention has for its object to improve the construction and action of
apparatus for churning milk or for mixing various liquids or materials.
In carrying out my invention I provide a rocking or swinging box the middle
part of which is square or rectangular, whilst the ends are in the form of oblique
pyramids each with a side flush with the top of the box their extreme ends being
diagonally opposite. The box is provided with a door or cover and with a
window. The inner sides of the box are, by preference, made with ribs or cor-
rugations and in the inside of the box there is attached a board or plate carrying
a number of blades or bars. When in use the particular shape of the ends of
the box assisted by the corrugations and the fixed blades effects the churning or
mixing of the contents in a speedy and satisfactory manner.
And in order that my said invention and the manner of performing the same
may be properly understood I hereunto append a sheet of explanatory drawings
to be hereinafter referred to in particularly describing my improvements.
Figure, 1, on the drawings is a plan, Figure, 2, a longitudinal vertical section,
Figure, 3, a transverse vertical section, and Figure, 4, a horizontal section with
parts removed of the improved apparatus. In these drawings the same reference
letters are used to mark the same or like parts whereever they are repeated.
In carrying out my invention I provide a box, A, the middle part of which is
square or rectangular, whilst the ends, B, are in the form of oblique pyramids
each with a side flush with the top of the box, their extreme ends being
diagonally opposite. The box, A, is provided with trunnions, C, which extend
out from each side and work in bearings in a stand or framing, D, and a
handle, E, is fitted to the box by means of which a rocking or oscillating motion
may be imparted to it. Access to the interior of the box, A, is provided for by
hinging the part, F, which forms the middle of the top of the box to the part
forming the top of one of the ends, B, the part, F, being held down by a bolt
and thumb screw attachment, G, and being thus made to form a tight-fitting door
or cover. The box, A, is held in the position shown in the drawings by a pin, J,
projecting from one side so as to engage with a catch, K, in a lever, L, so
centered on the framing, D, that it can be turned down out of the way when the
box, A, is to be rocked. A window or sight hole, H, is fitted in the top of one of
the ends, B, of the box; or it might be in the door or cover, F, through which
the condition of the contents may be observed at any time. A discharge plug, M,
(or it might be a drain cock); and a small pipe, N, to permit of the escape of
any gas generated, are also applied to the box. The inner sides of the box, A,
are, by preference, made with ribs or corrugations, P, which may be of any
suitable shape but are, by preference, made with sharp corners; and a board or
plate, Q, carrying a number of blades or bars, R, of square or other suitable shape
in cross section, is placed in the box so that it rests on supports, S, formed for
it on the sides of the box and the lower ends of the bars, R, just reach the bottom
of the box. Instead of the bars, R, a board having a number of slits or holes
formed in it may be attached to the plate, Q, or wire netting of a suitable mesh
carried in a frame attached to the plate, Q, may be used. When in this posi-
tion projections, T, on the underside of the cover, F, will, when the cover is
closed, bear on the top of the board, Q, and secure it so that the bars, R, will
always extend across the middle of the box irrespective of the position into which
the box may be rocked. This method of securing the board, Q, with its bars, R,
permits of these parts being easily removed on the cover, F, being opened.
Instead of the projections, T, the board, Q, may be held by a pinching screw
working through the cover.
When the box, A, has been charged, the cover, F, closed and the box released
from its catch, K, it can be rocked on its trunnions, C, the contents of the box
passing from end to end whilst the particular shape of the ends, B, of the box

page_text: give a swirling motion or a motion from side to side alternately to the contents
which motion assisted by the corrugations and the fixed blades effects the churn-
ing or mixing of the contents in a speedy and satisfactory manner.
The rocking motion may be given by hand as described; or by means of a
connecting rod from a rotating crank or equivalent. A weight may be arranged
to be wound up quickly on a barrel and whilst descending to give the rocking
motion required for a churning or mixing operation.
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:-
In apparatus for churning milk or for mixing various liquids or materials, a
box substantially of the shape described fitted with trunnions working in bearings
on a stand and provided with a door or cover the inner sides of the box being
made with or without corrugations and there being held in the box a removable
board or plate carrying a number of blades or bars or equivalents substantially
as herein before described and shown on the accompanying drawings.
