Complete Specification Left, 23rd May, 1889-Accepted, 29th June, 1889
PROVISIONAL SPECIFICATION.
Improvements in Curd Mills.
I ANDREW POLLOCK of Mauchline in the County of Ayr, Agricultural Engineer,
do hereby declare the nature of this Invention to be as follows:-
This Invention relates to machines or apparatus of the kind known as curd mills
which are employed for breaking up curded milk in the manufacture of cheese, a
feature of the improved apparatus being the employment of pins or pegs of round or
oval section in lieu of pins of rectangular cross section upon the spindle or barrel
by the rotation of which over a grating whereinto the pins enter the breaking up of
the curd is effected. This grating, which is situated between the usual box or
receptacle and the feed hopper in which is placed the curd to be acted on by the pin
barrel rotating therein, is composed of a series of bars extending transversely from side
bars but not quite meeting in the middle so that an unusually narrow longitudinal
open space is left immediately under the rotating spindle.
Dated this Twenty-third day of August 1888.

COMPLETE SPECIFICATION.
Improvements in Curd Mills.
I, ANDREW POLLOCK of Mauchline in the County of Ayr, Agricultural Engineer,
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 machines or apparatus of the kind known as curd mills
which are employed for breaking up curded milk in the manufacture of cheese a
novel feature of the improved apparatus being the employment of pins or pegs
of round or oval section in lieu of pins of rectangular cross section upon the spindle
or. barrel by the rotation of which over a grating whereinto the pins enter the
breaking up of the curd is effected.
In the accompanying drawings figure 1 is a plan figure 2 an end elevation of part
of a curd mill and showing the grating and rotating pin barrel and figure 3 is an
elevation of the pin barrel alone.
The grating which is situated between the usual box or receptacle B and the feed
hopper C in which is placed the curd to be acted on by the pin barrel D rotating
therein, is composed of a series of bars a extending transversely from side bars A but
not quite meeting in the middle so that an unusually narrow longitudinal open
space a is left immediately under the rotating spindle. The pin barrel D which
rotates in bearings a' in the ends of the grating is fitted with a series of pins d
arranged in helical rows the pins which are screwed into the barrel being made of
round oval or hexagonal cross section so as not to present sharp edges in breaking the
curd when passing through the grating A.
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 is
1. In a curd mill a pin barrel fitted with pins or pegs of round oval or similar cross
the more cat forth

page_text: 2. In a curd mill the combination of the grating A a constructed as described
and the barrel D provided with round or oval pins or pegs substantially as set forth.
Dated this Twenty-second day of May 1889.
