Improvements in Churns.
I, REGINALD HADDAN of the Firm of Herbert Haddan & Co. Patent Agents.
of 18 Buckingham Street, Strand W.C. London, Civil Engineer do hereby declare
the nature of this invention a communication to me from abroad by the Firm of
F. Meyer and Schwabedissen, of Herford Westphalia in the Empire of Germany,
Manufacturers, 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 churns for converting cream into butter and is
illustrated in the annexed drawing in which Fig. 1 is a vertical section partly
in elevation on line a. of Fig. 2, Fig. 2 being a horizontal section on line c. d. of
Fig. 1.
In this improved churn the cream follows continuously a certain course or path
until it is converted into butter, being thrown by centrifugal force against a wall
formed by or with the cover of the churn whence it passes down a ribbed wall to
be again lifted in a rotary ribbed vessel to be thrown against the said wall.
The churn comprises the vessel K having in its centre the hollow column P
within which rises the shaft having bearing in the upper end of said column and
projecting beyond the top of the latter to receive the hub k forming part of the
rotary vessel T. This vessel is of a conical shape flaring out to a horizontal rim
above and it is provided with interior ribs rising in vertical planes on its inside
wall. The bottom of vessel T is open and extends to near the bottom of vessel K
which latter vessel has also vertical ribs on its side walls.
The vessel K is surrounded by an outer vessel M so as to leave a space which
may be utilized for bringing the contents of vessel K to any desired temperature..
The underside of vessel M carries the bracket F in which slides the foot bearing p
of the shaft 1. This block p is supported upon a lever H which may be adjusted
by a set screw and nut N for the purpose of raising or lowering the shaft and
with it the vessel T so that the cream thrown out at the rim of said vessel may
pass between the rim and the cover through a narrower or wider opening n and
strike higher or lower upon the rim or wall W which forms the inner depending
flange of the cover D which closes the vessel K.
The bracket E carries the shaft of the hand wheel R the circumference of which
has a groove for reception of the leather or other strap or cord L which passes
round guide pulleys and around the pulley K¹ on the shaft v. By this means the
shaft and the vessel T will be set in rotation. The vessel T causes the cream to
rise by centrifugal force upon its wall and to be ejected at the upper edge against
the rim W whence it falls down the wall of vessel K to again be "drawn in at the
foot of vessel T. As butter is formed, this remains in the vessel K, for, being
lighter than butter milk it floats on the cream and butter milk S in the vessel K.
For convenience in emptying the vessel it is provided with two trunnions Z
(Fig. 2) which rest on pillars Z₁ (Fig. 1).
Having now particularly described and ascertained the nature of this said inven-
tion and in what manner the same is to be performed I declare that what I
claim is;
1. A churn having within an exterior vessel K an interior rotary flaring vessel T
adapted to be vertically adjusted to approach nearer to or further from the cover D
of the outer vessel in order to project the cream through the space n between its

page_text: rim and said cover against a depending flange W on the latter within the outer
vessel for the purpose set forth.
2. In the churn above described the construction whereby the outer vessel K is
enclosed within a vessel M for adjustment of the temperature of said vessel K and
whereby the shaft v of the inner vessel T ascends through a column P in vessel K
for avoiding contact with the contents of said vessel substantially as set forth.
Dated this 29th day of August 1895.
