Churn.
I, GEORGE CASPER OETERS, Gentleman, residing-at No. 1011 Dillon Street,
in the City of St. Louis, State of Missouri, U.S.A., 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 churn; and it consists in the novel
construction, combination and arrangement of parts, hereinafter described and.
claimed.
In the drawings :
The figure is a side elevation, partly in section, of my improved churn, the same:
being shown in position as required for practical use.
Referring by numerals to the accompanying drawings, 1 indicates a suitable.
metallic frame that may be firmly fixed to a table, or other stationary object by
means of a set-screw 2. Formed integral with this frame 1 at a point adjacent its
lower end is a box 3 which serves as a bearing for the shaft or stud of a beveled
gear-wheel 4, the same being provided with an operating handle 5.
Formed integral with the vertical portion of the frame 1 at points above the
box 3 are vertically aligned boxes 6 in which is journaled for rotation a vertical
shaft 7 carrying on its lower end a beveled pinion 8 that is in mesh with the
beveled gear-wheel 4. Located upon the upper end of this shaft 7 and operating-
in a horizontal plane is a grooved wheel 9.
Formed integral with the horizontal portion of the frame 1 and in vertical
alignment are boxes 10, in which is arranged for rotation a vertical shaft 11..
Upon this shaft 11 and between the boxes 10 is adjustably fixed a grooved-wheel
or pulley 12 of a diameter smaller than that of the grooved-wheel 9.
13 indicates the rotating dasher or agitator of my improved churn, the main
body of which is in the form of a slightly tapered cone, surmounted by a conical
body 14 having a much sharper taper than said main body. Formed in the under
side of this dasher or agitator is a semi-circular recess 15 and extending vertically
through the diametric center of said dasher is a bore or passage 16, in the upper
end of which is located a tubular sleeve 17. Into this sleeve 17 passes the lower
end of the shaft 11, and said sleeve is locked upon said shaft by means of a set-
screw 18 passing through the upper end of said sleeve and engaging upon said
shaft.
19 indicates a receptacle of any suitable size and form but preferably square, in.
which the rotating dasher or agitator operates.
In the practical operation of my improved churn, the frame is firmly locked upon.
the table or platform by means of the set-screw 2 and the milk or cream is placed
in the receptacle 19 in which the rotary dasher or agitator 13 is properly positioned.
The operator now manually engages the handle 5 and by the same rotates the
gear-wheel 4. Rotary motion thus obtained is imparted to the shaft 7 by means of
the beveled pinion 8 meshing with the gear-wheel 4, and consequently, to the
grooved-wheel 9 carried by the upper end of the shaft 7. The rotary motion of
this grooved-wheel 9 is imparted to the shaft 11 by reason of the belt 9 passing
around the grooved-wheel 12 carried by said shaft 11. Owing to the difference in
the diameters of the beveled pinion 8 and grooved-wheel 12 relative the beveled
gear-wheel 4, the grooved-wheel 9 and shaft 11 and the rotary dasher or agitator 13.

wheel 4. By thus rotating the dasher or agitator 13 in the milk or cream, said
milk or cream will be thorougbly agitated and the particles of butter-fat will be
separated from the milk or cream in a very short space of time.
A churn of my improved type is simple, both in construction and operation, is
durable, very easily cleaned and very efficient in use.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a churn, the combination of a conical body, and means for rotating the
same.
2. In a churn, the combination of a conical body having a semi-circular recess in
its under side, said body being provided with a diametrically arranged vertical bore
or passage, and suitable means for operating said.body.
3. In a churn, the combination of a suitable frame, a shaft arranged for rotation
in vertical bearings carried by said frame, a conical body carried by said shaft,
and means carried by the frame for operating said shaft.
4. In a churn, a suitable frame, a shaft arranged for rotation in vertically aligned
bearings in said frame, means carried by the frame for rotating said shaft, a sleeve
vertically adjustable upon the lower end of said shaft, and a conical body having a
recess in its under side carried by said sleeve.
