According to this our said Invention we employ a cylindrical taper barrel, within
which is a vertical central shaft, from which radial vertical dashers or "curdles "
extend; these are perforated, or may have elongated holes therethrough. There
is sufficient space between the outer extremities of the dashers and the interior of
the barrel for the introduction of ribs or breaks, and these we prefer should be
perforated with holes or openings as described in reference to the dashers or
curdles.
The vertical shaft carrying the dashers or curdles is provided with necessary foot-
step, and at its upper end a bevel wheel through which by means of a like wheel
shaft and hand wheel rotary motion in either direction is imparted to the dashers
or curdles. The driving apparatus being attached to a cross rail so as to be readily
removed for purpose of affording free access to interior of churn for purpose of
cleaning same.

According to this our said Invention we employ a cylindrical taper barrel, within
which is a vertical central shaft from which radial vertical dashers or "curdles
extend; these are perforated, or may have elongated holes therethrough. There is
sufficient space between the outer extremities of the dashers, and the interior of the
barrel for the introduction of ribs or breaks, and these we prefer should be
perforated with holes or openings as described in reference to the dashers or curdles.
The vertical shaft carrying the dashers or curdles is provided with necessary foot-
step, and at its upper end a bevil wheel, through which by means of a like wheel
shaft and hand wheel rotary motion in either direction is imparted to the dashers
or curdles. The driving apparatus being attached to a cross rail so as to be readily
removed for purpose of affording free access to interior of churn for cleaning
same.
Such being the nature and object of this our said Invention, we have annexed
a Sheet of Drawings illustrating the construction and details, in which Fig. 1 is an
elevation; Fig. 2, an elevation in section; Fig. 3, sectional plan; Fig. 4 and 5, details.
According to this our said Invention we employ a cylindrical taper barrel A,
within which is a vertical central shaft B, from which radial vertical dashers or
"curdles" C extend, these are perforated as at D, D, or the perforations may be
elongated holes. There is sufficient space between the outer extremities of the
dashers C and the interior of the barrel for the introduction of ribs or breaks E,
and the latter we prefer should be perforated with holes or openings F, as described
in reference to the dashers or curdles.
The vertical shaft B carrying the dashers or curdles C is provided with necessary
footstep H, and at its upper end a bevel wheel J, through which by means of a like
wheel K, shaft and hand wheel L, rotary motion in either direction is imparted to
the dashers or curdles. The driving apparatus being attached to a cross rail M
may, on removal of the wing nuts N, readily removed for purpose of affording free
access to interior of churn for cleaning same.
The dasher C may be released so as to be removable by raising the lock piece P,
whereon the shaft B can pass through the slot R, see Figs. 4 and 5.
Having thus fully described the nature and particulars of this our said Invention
together with the manner in which the same is to be or may be performed or
carried into practical effect, we would have it understood that we lay no claim to
any of the separate parts; what we do claim is, the combination of the perforated
dashers C with the brakes E, as and for the purposes described.
In witness whereof, we, the aforesaid, have hereunto set our hand and seal,
this Third day of July, in the year of our Lord One thousand eight
hundred and seventy-eight
