Improvements in Box Churns.
I, GEORGE MCNALLY, Chapel Hill, Lisburn, County Antrim, Coach Builder, do
hereby declare the nature of this invention to be as follows :-
-
This invention relates to churns and it has for its object to improve their
construction.
The churn consists of a box divided into two compartments by a partition having
two removable doors in it, one at the top and one at the bottom.
Fitted in one-
compartment is a shaft carrying a number of radial paddles or agitators which may
be of the shape of the figure 8. The shaft, which is, preferably, carried in ball
bearings, is driven by means of a crank or a wheel and handle at the outside. The
boss carrying the radial paddles can be screwed on to the shaft.
If the doors are removed and cream poured into the churn it fills up both
compartments and when the shaft is revolved and a churning action produced a.
constant circulation of cream takes place from one compartment to the other.
In one corner of the compartment containing the agitators a small zinc or
galvanized iron or tin box or receptacle is placed which can be filled with boiling
water and afterwards closed. This box can be fastened to the churn by a button or
similar arrangement. The boiling water heats the cream and facilitates the churning.
This arrangement obviates the necessity of mixing the cream with hot water as at
present. When the churning is complete the hot water is removed from the box and
is replaced by cold water to cool the contents of the churn and harden the butter.
When the doors of the partition are closed a small quantity of cream can be.
churned in the compartment containing the agitators.

Improvements in Box Churns.
1, GEORGE MCNALLY, Chapel Hill, Lisburn, County Antrim, Coach Builder, 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 churns and it has for its object to improve their
construction.
And in order that my said invention may be properly understood I have hereunto.
appended an explanatory sheet of drawings, whereon,
Fig. 1 is a vertical section of the churn and Fig. 2 a front view.
The churn consists of a box a divided into two compartments bc by a partition d
having two sliding or removable doors in it, one d', at the top and one d² at the
bottom. Fitted in one compartment is a shaft e carrying a number of radial paddles
or agitators f which may be of the shape of the fig. 8. The paddles are
preferably made of different lengths each alternate one being slightly shorter than

page_text: the other as shown in dotted lines at Fig. 2. The paddles may be made out of a
bent metal rod of square or round section.
The shaft, which is carried in a centre bearing el and a ball bearing e² is driven
by means of a crank, or a wheel and handle g, at the outside. The boss h carrying
radial paddles can be screwed on to the shaft.
If the doors d1, d2, are removed or slid back and cream poured into the churn
it fills up both compartments, and, when the shaft e is revolved and a churning
action produced a constant circulation of cream takes place from one compartment
to the other.
In opposite corners of the churn small triangular shaped zinc or galvanized iron
or tin boxes or receptacles i are placed which can be filled with boiling water and
afterwards closed. These boxes are provided with lifting handles i. The boiling
water heats the cream and facilitates the churning. This arrangement obviates the
necessity of mixing the cream with hot water as at present. When the churning
is complete the hot water is removed from the boxes and is replaced by cold water
in order to cool the contents of the churn and harden the butter.
When the doors of the partition d are closed a small quantity of cream can be
churned in the compartment c containing the agitators.
Instead of using the doors d', d², the openings, j', in the partition can be
unprovided with doors. In this case, when it is desired to churn only in the
compartment c, the compartment is filled up by a box or such like as indicated
in dotted lines at k.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
consider novel and desire to claim is :-
1. A box churn constructed and arranged substantially as hereinbefore described
with reference to the drawings annexed.
2. The combination with the churn of receptacles i for hot or cold water,
substantially as and for the purpose set forth.
