PROVISIONAL SPECIFICATION.
An Improved Method of Making Butter.
I, PATRICK MERRICK, of Ballycarron, Cashel, in the County Tipperary,
Ireland, Creamery Proprietor do hereby declare the nature of this invention to be
as follows:-
This invention relates to improvements in relation to that class of churning or
butter making usually carried on by rotatory churos.
According to this system of churning it is well understood that the operation of
making butter is carried on by rotating the churn continuously in one direction.
This practice of continuous rotatory motion I propose to alter and instead thereof
I introduce an intermittent rotatory motion, i.e., I cause the direction of rotation
to bo reversed at intervals without interrupting the process of churning. This
reversal of motion I propose to effect by prolonging the unincumbered end of the
shaft on which the churn is mounted, and fixing on same two suitable pulleys, one
fixed and the other loose, to correspond with the two pulleys already in use.
The fixed pulleys at both ends are driven by belts from the same counter shaft,
but one driving belt must be crossed so that the open belt will drive in one direction,
and the crossed belt in the opposite direction.
Independent guide rods are introduced for the purpose of throwing the respective
belts in or out of gear as required.
I also propose to alter the position of the draw off cock from its present position
at the end of the churn to a point in its side midway between its ends.
In dealing with my improved system of churning I would suggest that the churn
he rotated in one direction until the cream forms into globules when the buttor-milk
should be withdrawn and cold spring water added, when the motion may be reversed
intermittently for a short time. Water should again be added and drawn off until
it emerges from the churn as clean as it introduced.
The necessary salt is then introduced when the intermittent rotatory motion is
again proceeded with until a thorough mixture takes place and the butter appears.
As thus produced butter is of a firmer aud finer quality than any produced by
other means so far as I am aware.

COMPLETE SPECIFICATION.
An Improved Method of Making Butter.
I, PATRICK MERRICK, of Ballycarron, Cashel, in the County Tipperary,
Ireland, Creamery Proprietor, 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 relation to that class of churning or
butter-making usually carried on by rotatory churns.
According to this system of churning it is well understood that the operation of
making butter is carried on by rotating the churn-in some cases the beaters within
the churn-continuously in one direction.

page_text: This practice of continuous rotatory motion I propose to alter, and instead, I
introduce an intermittent rotatory motion, i.e., I cause the direction of rotation to
be roversed at intervals without interrupting the process of churning. This
reversal of motion I propose to effect by prolonging the unincumbered end of
the shaft on which the churn is mounted, and fixing on same two suitable
pulleys, one fixed and the other loose, to correspond with the two pulleys
already in use.
The fixed pulleys at both ends are driven by belts from the same counter shaft,
but one driving belt must be crossed, so that the open belt will drive in one direction,
and the crossed belt in the opposite direction.
Independent guide rods are introduced for the purpose of throwing the respective
belts in or out of gear as required.
I also propose to alter the position of the draw off cock from its present position
at the end of the churn to a point underneath midway between its ends.
The accompanying drawing will enable my said invention to be more readily
understood and' carried into practice. A is the barrel of the churn which is
mounted stationary.on suitable framework B, B. An ordinary sliding lid or cover C
is provided for the introduction of milk and water as required. D and E are the
fast and loose pulleys on the free ends of the shaft which carries the beaters.
It will be obvious that with an open and cross belt driven from the one counter.
shaft, and with the aid of suitable guide rods the required reversal of motion can
be readily and conveniently obtained.
F, shows the proposed position of the draw off cock by which alteration the
drainage of the churn may be more effectually accomplished, and to further
facilitate this end I form the bottom of the churn slightly convex as shown.
In dealing with my improved system of churning, I would suggest that the
churn be rotated in one direction until the cream forms into globules when the
butter-milk should be withdrawn and cold spring water added when the motion
may be reversed intermittently for a short time. Water should again be added
and drawn off until it emerges from the churn as clear as it is introduced. The
necessary salt is then introduced when the intermittent rotatory motion is again
proceeded with until a thorough mixture takes place, and the butter appears.
As thus produced butter is of a firmer and finer quality than any produced by
other means, so far as I am aware.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I would have it understood,
that what I claim is :-—
First. In the construction and arrangement of churns, the means whereby I
effect an intermittent reversal of rotatory motion for the purpose and in the manner
substantially as herein specified and set forth.
Second. In the construction and arrangement of churns, the position and
application of the draw off cock as herein described.
