30On the lower section of the operating
shaft are arranged the dasher and agitating
devices which are employed in connection
with the churn and freezer. On one side of
the lower section of the shaft are arranged
upper and lower right-angularly-projecting
dasher supporting arms, 28, in the lower one
of which is formed a bearing opening, 29,i
while in the upper arm is formed a notch or
recess, 30. With the bearing aperture, 29,
and notch, 30, is removably engaged the up-
per and lower portion 'of a dasher shaft, 31,
on which are arranged the dasher blades or
paddles, 32, which are here shown as pro-
vided with a series of apertures, 33, by
means of which the cream is thoroughly
agitated and churned. On the upper end of
the dasher rod or shaft, 31, is fixedly mount-
ed a spur gear pinion, 34, which is adapted
to engage the gear teeth, 26, arranged on
the inner side of the projection, 25, of .the
churn cover, whereby, when the cover and
churn are rotated by the sleeve, 17, the
movement thereof will be imparted through
the gear, 34, to the churn dasher to revolve
the same independently of the movement of
the churn body.
On. the opposite side of the lower section
of the operating shaft, 12, are arranged up-
per and lower supporting arms, 35, in which
is revolubly mounted an ice cream dasher
36, said dasher comprising a vertically dis-
posed shaft, 37, on which is arranged a se-
ries of radially-disposed blades, 38. In
addition to the dasher,.36, the lower sec-
tion of the operating shaft has arranged
thereon scraping blades, 39, which are sup-
ported on the outer ends of radially-pro-
jecting arms, 40, which are secured at their
inner ends to the shaft, 12. The arms, 40,
are of such length that the scraping blades,
39, will be held in close engagement with
the inner wall of the freezer can so that the
ice cream will be prevented from freezing
onto the sides of the can. When the device
is used in connection with an ice cream
freezer, the churn dasher is removed, this
being readily accomplished by reason of the
loose connection of 'the dasher shaft, 31,
p with the supporting arms, 28.
When the device is used as a churn,'the
.sleeve or ferrule, 17, is elevated on the op-
erating shaft so that the lowermost gear 19
is in engagement with the operating gear
5 wheel, 14, the raising of the sleeve, 17, being
necessary to provide for the difference in
height between the churn body and the
freezer can. When the device is used as a
freezer, the ferrule is slipped down onto the
o operating shaft until the upper gear, 18,
is in engagement with the operating gear
wheel. The gears, 18 and 19, are spaced
apart and at such distance from the crown
gear on the lower end of the sleeve or fer-
5 rule as to provide for the engagement of the ,crown gear with the teeth'on the covers of
the churn and freezer can. .
In. order to hold the sleeve in position
for engaging the gears, 18 and 19, with the
operating gear, and the crown gear, 20, with 70
the teeth on the covers of the churn or
freezer can, I provide a stop pin, 41, which
is adapted to be inserted through one of
a series of apertures, 42, formed in the op-
erating shaft. I also provide a transversely 75
disposed passage, 43, through the sleeve or
ferrule, 17, which is adapted to 'aline with
one of the passages 42 through the shaft and
to receive the stop pin 41 thereby holding
the sleeve up on the shaft and out of engage- so
ment with the tops of the churn or freezer
can and above the interlocking connection
between the sections of the shaft, thereby
permitting thetub and the churn or freezer
therein to be moved out from under the op- 85
erating mechanism so that the contents of
the churn or freezer may be readily re-
moved. The stop pin. 41 is preferably se-
cured to the upper section 9 of the operating
shaft by a chain or 'flexible connection where- 90
by said pin is prevented from being mislaid
or lost.
In connection with the churn, I preferably
employ a false lid or inner cover plate 44
which is supported upon suitable lugs 45 95
on the inner sides of the churn body and on
an annular collar 46 on the lower section
of the operating shaft. In one side of the
cover plate 44 is formed an inwardly pro-
jecting notch 47 to permit the insertion of a 100
churn dasher shaft. The notch 47 is
adapted to be covered by a fitted cover plate
48. The inner cover or lid 44 is provided
to prevent any milk or cream from splash-
ing into the upper portion of the cover 105
where the dasher operating gears are ar-
ranged. On the upper end of the operating
shaft is arranged a fly wheel 49. If de-
sired this wheel may be in the form of a
-rindstone 49a as shown in Fig. 5 of the 110
drawings, for the purpose of sharpening or
grinding knives or household articles.
From the foregoing description, taken in
connection with the accompanying drawings,
the construction and operation of the in- 115
vention will be readily understood without
requiring a more extended explanation.
Various changes in the form, proportion
and the minor details of construction may be
resorted to without departing from the prin- 120
ciple or sacrificing any of the advantages
of this invention as defined in the appended
claims.
Having thus described my invention, what
I claim as new and desire to secure by Let- 125
ters-Patent, is:
1. In a device of the class described, the
combination of a supportin- frame, a tub ar-
ranged below and spaced from said frame
and adapted to rece; .e a revoluble recepta- 13035
