Improvements in Churns.
I, WALTER OLDFIELD, of Fouldon, Brandon, in the County of Norfolk, Farmer,
do hereby declare the nature of this Invention (a communication to me from abroad
by William Nisbet Barrie, of Morrisburgh, Ontario, Canada, Manufacturer) to be as
follows:-
According to this invention the churn is suspended in the manner of a swinging
cradle or cot by rods at each end from the upper ends of two stands which by
preference are cross shaped. The churn is made in the form of a closed box of an
oval elliptical or similar form in side elevation. This box is provided with a lid at top
containing a glass pane; the top is also provided with one or more holes for ventilation.
The bottom is, at or near one end, provided with a stoppered outlet hole. In order to
facilitate the emptying out of the butter-milk the box can be tilted and for this
purpose one of the upper frame limbs on each side is jointed and can be made to
approach the other two upper limbs, the box suspension rods at that end being
unhooked or removed, thereby lifting one end of the box while the other end is rested
on a stop on the framing.
By the form of box described the cream is caused to strike the interior ends and
turn over back in an easy and natural manner without meeting any interior
obstructions to injure the natural formation or grain of the butter, all portions of the
cream being subject to the same amount of concussion, also thereby producing more
butter from a given quantity of cream. The interior of the box is easily cleaned and
kept clean. When the butter forms, the interior of the glass pane will become clear
thus indicating when to stop. The box is provided with handle or handles at each
end. A thermometer is also applied on one side, or through one of the ventilating
holes in a protecting tube, which should be easily removable.

Improvements in Churns.
I, WALTER OLDFIELD of Fouldon, Brandon in the County of Norfolk Farmer do
hereby declare the nature of this invention a communication to me from abroad by
William Nisbet Barrie of Morrisburgh, Ontario, Canada, Manufacturer and in what
manner the same is to be performed to be particularly described and ascertained in
and by the following statement :-
:-
According to this invention the churn is suspended in the manner of a swinging
cradle or cot by rods at each end from the upper ends of two stands which by
preference are cross shaped. The churn is made in the form of a closed box of an
oval elliptical or similar form in side elevation. This box is provided with a lid at
top containing a glass pane; the top is also provided with one or more holes for
ventilation. The bottom is at or near one end, provided with a stoppered outlet hole.
In order to facilitate the emptying out of the butter-milk the box can be tilted.
In the accompanying drawing I have shewn a churn of this description. Figure 1
is a vertical longitudinal section. Figure 2 a vertical transverse section and Figure 3
a plan of the box A or churn proper in which the butter is made. Its form as shewn
in Figure 1 is approximately elliptical with the bottom flat or the bottom may be of a
curve similar to the top. The lid B is made a good fit and is provided with a glass
pane C shewn about full size in the sectional view Figure 4. The lid has two knob
handles Deach with ventilation hole through as shewn also about full size in the
sectional view Figure 5. E is a plug for outlet hole, and F F are two handles for
taking hold of from either end to actuate the churn in the manner of a swinging
cradle or cot.
Figure 6 is an end view of such a churn box A suspended by four rods G two at
each end and each two, connected by a cross bar to form a bail. These rods are jointed
to the upper limbs H of two Andreas cross shaped frames. One upper limb H and
one lower limb H' of each frame are made to pivot the left hand upper and the right
hand one in Figure 6 (or vice versa) for affording facility for tilting the box A when
the butter milk or rinsing water is to be run out at E. Figure 7 shows the churn in
such a tilted position, one hinged leg H of each frame being shifted towards the
vertical. Or as shewn in Figure 8 an upper limb H in each frame is moved for the
purpose of conveniently tilting the box A. Or as shown in Figure 9 the tilting may
be effected by simply unshipping the bail or cross bar which connects the lower ends
of two suspension rods G and resting the loweréd end of the box A on the stops I.
By the form of box described the cream .is. caused to strike the interior ends and
turn over back in an easy and natural manner without meeting any interior
obstructions to injure the natural formation or grain of the butter, all portions of the
cream being subject to the same amount of concussion also thereby producing more
butter from a given quantity of cream. The interior of the box is easily cleaned and
kept clean. When the butter forms, the interior of the glass pane C will become clear
thus indicating when to stop.--

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what 1
claim as the invention communicated to me is.
First In rocking cradle churns making the churn box of oval or elliptical form
or with rounded ends substantially as and for the purposo set forth.
Second-The rocking cradle churn box A with pane C substantially as shewn and
described.
Third-The rocking cradle churn described with reference to the accompanying
drawings.
