Improvements in and connected with Butter Churns.
I STIERLIN HAUSER of the City of Rigi-Scheidegg, Switzerland Doctor of Chemistry
o hereby declare the nature of this invention and in what manner the same is to be
erformed, to be particularly described and ascertained in and by the following
tatement:
My invention relates to an improved butter churn, in which the cream is agitated
Iternately in opposite directions and the manner in which I prefer to carry my
nvention into effect is shewn in the accompanying drawing of which
Fig. 1 is a front view.

I STIERLIN HAUSER of the City of Rigi-Scheidegg, Switzerland Doctor of Chemistry
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 :-
My invention relates to an improved butter churn, in which the cream is agitated
alternately in opposite directions and the manner in which I prefer to carry my
invention into effect is shewn in the accompanying drawing of which
Fig. 1 is a front view.
Fig. 2 is a ground plan.
Fig. 3 is a cross section.
Fig. 4 is a top view of the agitator.
Fig. 5 a detail.
The churn consists of a cylindrical vessel A with lid B, which is fastened by
means of a bow F secured with a bolt and a perpendicular agitator shaft C, pro-
vided with numerous blades D which are placed spirally in relation to each other."
Small hand churns according to my invention are driven by means of a pulley E,
fixed on the vertical shaft C, provided with grooves in which ropes or straps may
be laid, so that when pulling each end alternately, in see-saw fashion, the shaft is
caused to revolve alternately right or left about.
When the churn is too large for being worked in that fashion, the pulley E is
replaced by a cog-wheel (Fig. 5) in which is geared a cog-wheel segment, attached
to a long lever, which has its turning point at x in a pin fitted through the
lid B.
As a rule 6-8 minutes rapid agitation suffices to produce the butter, and after-
wards the butter milk is allowed to run away, being replaced by a like quantity of
water, with which the machine is again agitated for the purpose of washing and
kneading the butter, the operation being repeated until the water runs away
clear.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be perforined, I declare that what I
claim is :-
An improved churn in which the cream or milk is agitated by means of an
agitator, worked alternately right and left about, which is provided with numerous
blades placed in a spiral line relatively to each other substantially in the manner
described and shewn in the drawing.
