MATTE O'MARROW, OF PARIS, TEXAS.
SPECIFICATION forming part of Letters Patent No. 626,623, dated June 6, 1899.
Application filed June 25, 1898. Serial No. 684,464. (No model)
To all whom' zt mxy concern
Be it known that I, MATTIE O'MARROv, of
Paris, in the county of Lamar and State of
Texas, have invented a new and useful Im-
5 provement in Churns, of which the follo wing
is a specification.
The object of my invention is to provide a
simple and effective churn-operating inech-
anism which does not need any particular
io form of receptacle to hold the cream, but
which is designed to be applicable for churn-
ing butter in a bowl, a jar, a bucket, or any
other receptacle in which the cream may be
15 A further object is also to provide such a
construction as may be easily made and re-
paired by any carpenter or farmer without
having to rely upon the manufactories of
20 My invention operates upon the principle
of aerating and cooling the cream at the same
time it is being churned and also of obstruct-
ing the centrifugal action of the cream by a
breaker; and it consists in the peculiar con-
25 struction and arrangement of parts which I
will now proceed to fully describe with refer-
ence to the drawings, in which-
Figure 1 is a front view with a stone jar
shown in dotted lines as a receptacle for hold-
30 ing the cream. Fig. 2 is a side view. Fig.
3 is a top plan view. Fig. 4 is an under side
view of the aerator, and Fig. 5 is a cross-sec-
tion of the current-breaker.
In the drawings, A represents a base hav-
35 ing short legs or strips Z in front for support-
ing it a short distance from the floor or table.
B B are two vertical side pieces. C is a ver-
tical back piece, and D a top piece, all of
which parts may be conveniently made of
40 wood securely nailed or screwed together.
The base A forms a table upon which is sup-
ported the detachable receptacle J (shown in
dotted lines) for containing the cream to be
churned. This receptacle may be an earth-
45 enware jar, a bucket, pail, tub, crock, or any
other convenient receptacle. The side pieces
B B are preferably cut away with a semicir-
cular opening on the side to give more room
for the hands in placing the receptacle J in
50 position or taking it out. The back piece C
has its lower part formed into short legs ' l'
and its top part extended above the piece D
in the form of a handle C' for moving the
churn or steadying it while being operated.
On the top piece D and in the angle between 55
it and the handle C' is secured a short arm D'.
The front end of this arm is slotted vertically
to form a bearing b, and the front end of top
piece D is also slotted vertically to form a
bearing b', in which two bearings there re- 60
volves and is supported from its upper end
alone a revolving shaft h, having rigidly at-
tached to the same between the bearings b
and b' a grooved pulley G. To the lower end
of the revolving shaft his detachably secured 65
by a set-screw h' an aerator and beater H.
This consists of a tapered tube smallest at
the top, which is closed, and largest at the
bottom, where it is provided with a horizontal
disk K. The tapered tubular portion of the 70
aerator is provided along its sides with a se-
ries of curved openings n, having flanged
edges, and to the under side of the bottom of
the disk is attached a bridge-piece o, which
is perforated to receive the shaft h and hold 75
the aerator concentric. To the under side of
the disk there are attached a set of three,
more or less, revolving wing beaters r and
mounted to revolve freely upon loop-shaped
axes r', extending down from the disk. 80
I is a vertical shaft extending through a
bearing in the top piece D of the framework.
This has rigidly attached on its upper end,
above the piece D, a grooved pulley m, and
below the piece has a detachable current- 85
breaker I', formed of a V-shaped piece of
metal arranged longitudinally on the shaft I
and detachably connected thereto by a set-
screw s. This current-breaker, like the aera-
tor, is supported only at its upper end and go
has no bearing at its lower end, but simply
dips down into the cream to arrest and break
up the circular or centrifugal action of the
cream as caused by the revolving beater and
On the rear side of the vertical back piece
C of the main frame there is mounted a short
axial bearing, upon which is supported and
turns a large grooved wheel E, having a turn-
ing crank or handle F. Around the periph- loo
eral groove of this wheel there passes an end-
less cord or belt t, which passes over two
guide-rollers a a at the upper edge of the
framework and then extends horizontally
