Improvements in Churns.
I, EMMETTE W. SETTLE, Gentleman, residing at Slater, in the County of
Saline. State of Missouri, and United States of America, 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 improvements in "churns" and consists in the novel
arrangement and combination of parts, as will be more fully hereinafter described
and designated in the claims.
My improvements consist in the construction of a means for operating the churn-
dasher by revolving the same instead of the old reciprocatory method.
In the drawings:-
-
Fig. 1 is a front detail elevation of my complete invention.
Fig. 2 is a front sectional elevation showing parts sectioned to show the position
of other parts.
Fig. 3 is a side elevation looking from the right hand of Fig. 1.
Fig. 4 is a transverse sectional view taken on the line A-A in Fig. 1.
Fig. 5 is a detail plan sectional view of one of the clamps and adjusting rods
used to hold the churn in position.
Fig. 6 is a modified construction of the churn clump.
Fig. 7 is an additional modification of the same.
Fig. 8 is a detail view showing the manner of securing the dasher-rod to the
driving-shaft.
Referring to the drawings:
1 indicates a base platform surmounted at each side by longitudinal uprights 2
and 3 secured to said base by angle irons 4.
The upper ends of said uprights 2 and 3 are connected by a curvilinear strip 5,
the highest point of same being above and intermediate of the two uprights.
Said connecting strip 5 is secured upon the inner side of said uprights 2 and 3
by rivets 6 and connecting said uprights at a point below that to which the piece 5
is connected is secured a cross-piece 7 having downwardly projecting lugs 8 upon
its end and by means of which it is secured to the inner sides of the uprights 2
and 3 by bolts 9. The churn 10 is adapted to he placed upon the base I, inter-
mediate of the two uprights 2 and 3 and held in the stationary position by means
of clamps 11.
As shown in Figs. 1, 2, 4, and 5 the clamp 11 consists of two distending arms 12,
provided with a rearwardly projecting lug portion 13, which is provided in its rear
centre with a circular opening 14.
A vertical slot 15 projects into the lug portion 13 and is wide enough for the
placing therein of a nut.
The adjusting screw-threaded rod 16 is provided upon one end with a screw-
threaded portion 17, the same being of less diameter than the main portion of
the rod.
The nut 18 is dropped into the slot 15 and the portion 17 of the rod 16 is inserted
through the opening 14 and screwed into the said nut 18, said nut being jammed
thereon to allow of the turning of said rod 16 independent of the clamp 12.
The outer end of the rod 16 is screw-threaded similar to the remainder of its
length and provided with an adjusting thumb nut 19, which is jammed thereon by
means of a nut 20.
The arms 12 upon their inner sides are provided with flexible strips 21, preferably
made of rubber and having teeth 22, which project outwardly.

Said strips are secured to tid arms by rivets 23, and are adapted to clamp and
hold the churn in position by the adjustment of the rod 16.
The uprights 2 and 3 are provided upon their inner sides with supporting
blocks 24, and through which and the uprights 2 and 3, are placed metallic
internally screw-threaded bushings 25, said bushings being in horizontal alignment
and adapted to receive the adjusting rod 16.
By the adjustment of the clamp rod 16 in the bushings 25, the arms 12 are
either pushed towards each other or the opposite, said arms 12 remaining in the
stationary horizontal position independent of the movement of the rods 16.
The churn cover 26 is provided with an opening 27 through which the dasher
rod 28 projects, with the dasher 29 located on the lower end of same.
The upper end of the dasher-rod 28 is squareil and upon two sides are provided
corrugations 30 which are a lapted to be engaged by two plates 31 provided upon
the inner sides with corrugations.
Said plates are bolted upon the lower square end of the driving-shatt 32, which
is also provided with corrugations adapted to be engaged by those upon the inner
sides of the plates 31,
The dasher-rod 28 is removed from between the plates 31 from the side, and
when in position, is held by thumb-screws 33, as shown in detail in Free, S.
The rod 32, or rather driving-shaft, is in minted vertically in a bearing 34 in the
cross-piece 7 and a bearing 35 in the curvilinear strip 5, both of sail bearings
being in alignment and a downward movement of said Shatt 32 is prevented by a
flange 36 which revolves upon the top of the cross-piece 7.
The bearing 34 is provided by a partial circular opening in said cross-piece 7
and by a partial opening in a cap 37, which is secured in said cross-piece 7, so that
its ends are flush with the edge of said cross-piece.
Mounted upon the shaft 32 above the flange 36 is a pinion 38, the teeth of which
are engaged by those upon a driving-gear 39 mounted upon a horizontal shaft 40.
A V-shaped bracket 41 is secured upon the inner side and near one end of the
strip 5 and projects inwardly towards the shaft 32, and in its apex is provided a
bearing for said shalt 40 having flanges-12 located thereon to prevent any horizontal
longitudinal movement of the shaft 40,
The shaft is also mounted in a bearing provided by a metallic bushing 43 located
in the upright 3 and strips 5 and in alignment with the bearing in the apexial
bracket.
The shaft 40 projects outwardly from the upright 3 and upon the end of same
is secured a crank 44 by means of which the shaft is revolved by hand.
If desired to run the churn by water or other power the same could be trans-
mitted to the shaft 40 and in this case a pulley would be provided thereon in the
place of the crank 44.
To allow for wear on the lower side of the flange 36 the same is made adjustable
in order that the rod can be raised to compensate for the wear in order to keep the
pinion 38 and the gear-wheel 39 in operative order.
The churn dasher 29 consists of two sets 45 and 46 of extending bars 47 which
project towards the quadrantal points of the square. Said sets of bars are located
in a horizontal position and some distance apart and upon the dasher-rod 28, and
each of the four bars 47 in both sets are connected by vertical strips 48 which
when the churn-dasher is rotating agitate the contents of the churn.
In Fig. 4 the arms 12 of the clamp are shown without the rubber teeth 22 and
it will be readily seen that owing to the shape of these arms any size of churn can
be accommodated.
In Fig. 6 is shown a construction wherein the clamping arms 49 are made
curvilinear in form and of spring material in order that they will adjust themselves
to any size of churn.
In order that they will be held secure in any desired position, the adjusting
bar 50 is made rectangular in form and provided upon one side with backwardly
projecting teeth 31.

page_text: These teeth are adapted to be engaged by a spring controlled rod 52, the
spring 53 being located in an opening 54 in the upright 3 and which opens into
the opening 55 through which the rod 50 is adapted to reciprocate.
The spring 53 has one end secured in said rod 52 and the other engages the end
of the opening 54 and normally keeps said rod in engagement with the teeth 51.
The rod 52 is provided upon its outer end with a knob 56 by means of which it
is pulled outwardly to allow the ajatment of the rod 50, and a collar 57 is secured
between said knob 56 and the edge of the upright 3, to limit the mwand movelicat
of said rod.
In Fig. 7 is shown a modification embodying two circular and adjustable arms 58,
which are pivoted upon the end of a rod 59, the operation of which is similar to
that of the rod 50 as shown in Fig. 6.
A bolt 60 passes through said arms 58 and the rod 59 and by loosening of same
the arms may be adjusted in any desired position.
My invention is extremely simple in its operation and by the revolving of the
shaft 40 by means of the crank 44, the gear 39 is revolved and owing to its
engagement with the pinion 38 upon the shaft 32 said shaft is revolved and also
the churn dasher upon the lower end of the rod 28, thus carrying out the function
of the churn.
The clamps 11 enable adjustment to suit different sizes of churns and are adapted
to hold the same in a rigid position.
The clamp as shown in Fig. 5 is especially designed for holding the churn in the
stationary position, as the engagement of the teeth with the charm prevents any
turning of the same.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what 1
claim is
1. An improved churn wherein the contents of same are adapted to be agitated
by the rotating of a churn-dasher therein, and means provided for operating said
