CHURN-DASHER.
SPECIFICATION forming part of Letters Patent No. 786,525, dated April 4, 1905.
Application filed November 28, 1904, Serial No. 234,683.To (11 who2 it may concern:
Be it known that I, SILAS C. SmIONs, a citi-
zen of the United States, residing at Rising-
star, in the county of Eastland and State of
Texas, have invented a new and useful Churn-
Dasher, of which the following is a specifica-
tion.
This invention relates to churn;dashers, and
has for its object to provide an improved hand-
operated device of this character capable of
being used in any ordinary form of churn-
body-such, for instance, as a stone crock-
without any alteration or addition thereto. It
is futhermore designed to arrange the device
for convenient reciprocation by hand and at the
same time to effect rotation of the rotary mem-
ber of the device, so as to obtain an effective
agitation of the cream.
With these and other objects in view the
present invention consists in the combination
and arrangement of parts, as will be herein-
after more fully described, shown in the ac-
companying drawings, and particularly point-
ed out in the appended claims, it being under-
stood that changes in the form, proportion,
size, and minor details may be made within
the scope of the claims without departing
from the spirit or sacrificing any of the ad-
vantages of the invention.
In the accompanying drawings, Figure 1 is
a perspective view of a churn-dasher embody-
ing the features of the present invention,
parts being broken away to expose the inte-
rior thereof. - Fig. 2 is a central longitudinal
sectional view of the dasher.
Like characters of reference designate cor-
responding parts in both figures of the draw-
ings.
The present dasher includes a central up-
right tubular socket 1, which is provided about
midway of its ends with an external annular
flange or shoulder 2. Substantially radial and
downwardly-bowed arms 3 extend outwardly
from the socket above the flange 2 and carry
at their outer ends an upstanding circular
band 4, which is pierced at regular intervals
by openings 5. Braces 6 extend outwardly
from the socket adjacent the upper side of the
flange 2 and incline upwardly with their outerends connected to the inner sides of the re- 50
spective arms, so as to effectually brace the
latter.
Upon the lower portion of the socket 1 is a
rotary dasher-wheel in the nature of a pro-
peller comprising a tubular hub 7, rotatably 55
embracing the socket and provided with ra-
dial propeller-blades 8, there being a cap or
plate 9 applied to the lower end of the socket
with its.peripheral edge portion projected be-
yond the socket and forming a flange or col- 6o
lar for the support of the hub 7, which is held
against end wise movement between the flange
2 and the cap 9.
Suitable upright breakers 10 in the nature
of flat metallic plates are secured to the inner 65
side of the rim or band 4 and are located just
outside of the path of the propeller-wheel.
For the manipulation of the device a suit-
able dasher staff or handle 11 is introduced
into the open upper end of the socket 1 and is 70
manipulated to reciprocate the dasher within
any ordinary or preferred form of churn-
body. During the reciprocation of the dasher
the arms 3 and the braces 6 operate as sub-
stantially horizontal breakers, while the pro- 75
peller-wheel rotates in one direction during
the upward movement of the dasher and in
the opposite direction during the downward
movement of the dasher, thereby producing
alternate upward and downward streams or 8o
currents in the cream and also dashing the
cream against the breakers 10, thereby pro-
ducing currents in various directions and
breaking up the same, so as to effectually agi-
tate the cream and quickly bring the butter. 85
The function of the rim 4 is to somewhat
confine the swirl produced by the dasher-
wheel in order that said swirl or current may
be directed alternately upward and down-
ward, and the band is provided with the open- 90
ings 5 to permit some of the cream being vio-
lently dashed out through the openings, so as
to be broken up by contact with the edges
thereof.
From the foregoing description it is appa- 95
rent that the rigid members of the present
dasher are connected to the central socket
member in an exceedingly simple and durableNo. 786,525.
