HOMER TONY WILSON AND BLEUFORD BRADFORD SANDERS, OF DALLAS,
TEXAS.
CHURN.
SPECIFICATION forming part of Letters Patent No. 314,501, dated ]March 24, 1885.
Application filed May 13, 1884. (No model.)To all whon it m7ay conceriz:
Be it known that we, HOMrER T. W ILSON and
BLEUFORD B. SANDERS, of Dallas city, in the
county of Dallas and State of Texas, have in-
5 vented certain new and useful Improvements
in Rotary Churns; and we do hereby declare
the following to be a full, clear, and exact de-
scription of the invention, such as will enable
others skilled in the art to which it pertains to
io make and use it, reference being had to the ac-
companying drawings, which form part of this
specification.
Our invention relatesto an improvement in
rotary churns; and it consists in the combina-
15 tion of the dasher-shaft made screw-threaded
at its upper end, and having a dasher secured
to its lower one; a pinion which is applied to
thescrew-threaded part of the shaft, and which
has a rising and falling movement thereon;
20 the driving-wheel which operates the two pin-
ions, and through them the two dashers, and
the sleeve, which is connected to the lower
pinion and one of the dashers, as will be more
fully described hereinafter.
25 The object of our invention is to provide
an automatic mechanism in connection with
one of the dashers, so that after the churning
is completed it is only necessary to reverse
the movement of the driving-wheel, when one
30 of the dashers will automatically be thrown
out of gear and remain stationary, so that the
remaining dasher can be used in gathering
the butter.
Figure 1 is a side elevation of a churn em-
35 bodying our invention, shown partly in sec-
tion. Fig. 2 shows the wheel which is to be
thrown out of gear with the driving-wheel in
the separated position.
A represents the body of the churn, and B the
40 cover. This cover is fastened tightly in po-
sition upon the churn by means of the sta-
tionary piece C, which is secured to its under
side, and the movable piece D, which is moved
horizontally back and forth by the set-screw F.
45 Upon the top of this cover is secured a suit-
able standard or frame-work, E, upon which is
journaled the driving-shaft G, which is oper-
ated by means of the handle H. One of the
dashers, I, is connected to the sleeve J, while
50 the second dasher is connected to the verti-
cal shaft L in the usual manner. This sleeveand shaft are provided with pinions which
mesh with the driving-wheel, so as to cause
the two dashers to revolve in opposite direc-
tions in the usual manner. 55
No special claim is made upon the dashers,
which are to revolve in opposite directions,
for the sleeve, the shaft, the pinions on the
sleeve and shaft for gearing with the operat-
ing-wheel are conceded to be old. Thegreat 6o
trouble with this form of churn is that as the
two dashers, as heretofore made, always re-
volve together they must be removed from the
churn when the churning is completed, for
the purpose of gathering the butter. Our 65
special aim has been to overcome this defect,
and to so construct the parts that one of the
dashers can be made to remain stationary and
the other made to revolve, for the purpose of
gathering the butter. For this purpose the 70
upper end of the shaft which passes through
the sleeve, and which has the pinion O secured
to its upper end, is made screw-threaded, as
shown at P, so that the pinion O will auto-
matically follow these threads when the mo- 75
tion of the wheel is reversed, and thus be
forced downward upon the shaft and out of
gear with the driving-wheel when its motion
is reversed. When both dashers are to be re-
volved together, the pinion O is first moved 80
up by hand until its upper edge engages with
the teeth of the driving-wheel, and then, when
the driving-wheel is turned toward the right,
this pinion follows the threads and moves up-
ward upon the shaft until it strikes against 85
the under side of the nut R, which is rigidly
secured to the upper end of the shaft, and
then the shaft begins to revolve and operate
the dasher connected to its lower end. As
soon, however, as the operator wishes to gather 90
the butter, after the churning is completed, it
is is only necessary to reverse the motion of
the driving-wheel, when the pinion will follow
the threads upon the shaft and move down
out of gear with the driving-wheel. By re- 95
moving the set-screws the dashers can be de-
tached from their shaft for the purpose of be-
ing washed.
Having thus described our invention, we
claim- too
