Improvements in Churns for Producing Butter.
We RICHARD STOCKDALE, of Halton, in the County of Lancaster Baize Manu-
facturer, and THOMAS STOCKDALE, of Darwen in the County aforesaid, School-master
do hereby declare the nature of our invention for "IMPROVEMENTS IN CHURNS
FOR PRODUCING BUTTER," to be as follows:-
This invention relates to improvements in churns, by combining therewith a jacketing
for hot or cold water so as to ensure the desired temperature within the churn, and to
the contents thereof.
According to our invention we construct the body or main portion of the churn of
metal, of oblong or other form the bottom of which is semicircular, the bottom and
sides of the churn are surrounded by a casing or jacket into which warm or cold water
is introduced according as the temperature of the milk or cream requires raising or
lowering. A tap is placed at the bottom of the jacket or casing for the purpose of
drawing off the water when desired.
A horizontal shaft passes through the body of the churn on which are mounted the
beaters, consisting of an arrangement of perforated arms or vanes, these can be taken
out for the purpose of cleaning the churn, and on one end of the shaft is a handle or
pulley for transmitting the necessary rotatory motion to the arms or vanes.
The top
of the churn is closed by any suitable lid, and the whole stands on a trussle or other
like device.

page_text: We, RICHARD STOCKDALE of Halton in the County of Lancaster, Baize Manu-
facturer, and THOMAS STOCKDALE of Darwen, in the County aforesaid, Schoolmaster,
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 churns by combining therewith a jacketing
for hot or cold water so as to ensure the desired temperature within the churn and to
the contents thereof.
According to our invention we construct the body or main portion of the churn of
metal of oblong or other form, the bottom of which is semicircular the bottom and sides
of the churn are surrounded by a casing or jacket into which warm or cold water is
introduced according as the temperature of the milk or cream requires raising or
lowering. A tap is placed at the bottom of the jacket or casing or jacket for the
purpose of drawing off the water.
A horizontal shaft passes through the body of the churn on which are mounted the
beaters consisting of an arrangement of plain or perforated arms or vanes, these can
be taken out for the purpose of cleaning the churn, and on one end of the shaft is a
handle or pulley for transmitting the necessary rotary motion to the arms or vanes.
The top of the churn is closed by any suitable lid, and the whole stands on a trestle
or other like device.
Such being the nature and object of our said Invention the following is a complete
description of same, reference being had to the accompanying drawings forming a part
of this specification in which,
Fig. 1 is a side elevation of our improved churn.
Fig. 2 is an end elevation of same.
Fig. 3 is a section of body of churn through line A. B. of Fig. 2.
Fig. 4 is a section of body of churn through line C. D of Fig. 1.
Fig. 5 is a detail of beater and handle.
According to our invention we construct the body or main portion 1 of the churn of
metal of oblong or other form, the bottom 2 of which is semicircular, the bottom 2
and portion of the ends or sides 3 of the churn are surrounded by a casing or jacket 4
into which warm or cold water is introduced according as the temperature of the
milk or cream requires raising or lowering. A tap 5 is placed at the bottom of the
jacket or casing 4 for the purpose of drawing off the water.
A horizontal shaft 6 passes through the body 1 of the churn on which are mounted
the beaters 7. 7. consisting of an arrangement of perforated arms or vanes 7 these can
be taken out for the purpose of cleaning the churn, and on one end of the shaft is a
handle 8 or pulley for transmitting the necessary rotary motion to the arms.
The top of the churn is closed by any suitable lid 9 and the whole stands on a
trestle 10, or other like device.

page_text: The water is introduced into the jacket or casing 4 through the aperture 3^, and the
body of the churn is kept steady whilst the handle 8 is being turned by means of the
two pivots 11-11 on the body of the churn 1 which rest in the gearings 11ª on
the frame or trestle 10 and the churn is thus held securely.
The churn is free to be tilted on its pivots or supports 11-11 that its liquid
contents may be poured out at the spout 13 in which is a sieve 13ª through which the
milk passes.
Having now particularly described and ascertained the nature of our said
Invention, and in what manner the same is to be performed, we declare that what
we claim is
The rotary beater and its containing vessel when employed in connection and in
combination with an outer water containing jacket such as 4 for purpose and
substantially as illustrated and herein fully described.
