residing at Henderson, in the County of Arapahoe, Colorado, 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 has relation to churns, and the object is to provide a churn which
shall be simple of construction, durable in use, and comparatively inexpensive of pro-
duction, and which may be operated with a minimum expenditure of power and
effectively perform its work.
With this object in view, the invention consists of certain features of construc-
tion and combination of parts which will be hereinafter fully described and
claimed.
In the accompanying drawings:-
Figure 1 is a side elevation of my improved churn;
Fig. 2 is a longitudinal sectional view;
Fig. 3 is a similar view, on an enlarged scale, through the slotted dasher-shaft
and its sliding block;
Fig. 4 is a similar view through the hollow dasher shaft and its sliding block.
Fig. 5 is a transverse sectional view through the sliding blocks, and
Fig. 6 is a plan view, on a small scale, of the churn cover.
In said drawings, 1 denotes the churn body, shown in the present instance as
of cylindrical shape. 2 denotes the base upon which the body is supported, and 3
two standards uprising from said base and provided at their upper ends with a
connecting cross piece 4, having a rectangular bearing opening 5.
sliding blocks which are adapted to the rectangular opening. The adjacent faces
of these blocks are provided with longitudinal grooves 7.
6 denotes two
9 denotes a tubular dasher shaft, the upper end of which is provided with a
head 91 that is set in a recess 10 in one of the blocks, and which is held therein by
a bolt 11. The lower end of the tubular dasher shaft is threaded and is connected
with a disk 15, which is secured to a dasher 16 having a central opening 17.
18 denotes a dasher shaft which extends through the hollow dasher shaft 9,
and has its upper end secured in a groove of one of the slide blocks and being par-
tially surrounded by the other slide block, thus forming a spline or key to prevent
the rocking of said blocks one with respect to the other, and said blocks having a
movement in the rectangular bearing of the cross-bar 4, will be prevented from
rocking sidewise or wabbling, but will be guided in a true vertical direction. The
lower end of the shaft 18 projects through the tubular shaft 9, and is provided with
a dasher 19, similar to the dasher 16 on the tubular shaft.
20 denotes a crank shaft journaled in bearings in the upper end of the stan-
dards, and 21 denotes links connected to the crank shaft at their upper ends and
with their lower ends pivoted to the sliding blocks. This shaft may be rotated in
any suitable manner or by any suitable power, and as shown in the accompanying

page_text: drawings, I have illustrated a crank 22 by means of which the shaft may be turned,
but do not wish to confine myself to the same.
It is evident that when the shaft is rotated, the dashers will be reciprocated in
opposite directions, and will thus more effectively churn the cream into butter.
In order to facilitate the separation of the churn body from the operating
mechanism for the purpose of removing the butter and cleaning the parts, I have
provided the churn with a removable cover a divided centrally and hinged together
as shown at b. A latch c is connected to one of the hinged sections and engages
a catch d on the other section, thus holding the two sections together around the
dasher shafts.
To prevent the vertical movement of the cover with respect to the body, I pro-
vide hooks e, the lower ends of which engage lugs f projecting from the sides of the
churn body.
When it is desired to remove the body for taking out the butter, or any other
purpose, the sections of the cover are swung apart to free the dasher shafts, the
hooks disengaged from the lugs, the bolts connecting the links 21 with the blocks (
loosened, the links swung back and the blocks lifted from the bearings and the
dashers withdrawn from the body.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:-
In a churu, the combination with the churn body and the standards, of a cross-
bar secured thereto near their upper ends and provided with a rectangular bearing
opening, sliding blocks fitted in said opening and provided with longitudinal grooves
in their inner faces, dasher shafts secured to said sliding blocks, one of said dasher
shafts being located in the groove of said blocks and forming a spline or rib for
guiding the blocks in their vertical movement, one of said dasher shafts being
tubular and the other projecting through it, dashers secured to the extreme lower
ends of said dasher shafts, a top consisting of two hinged sections, means for
securing the top to the churn body, and means for securing the sections about the
dasher shafts, a crank shaft journaled in bearings in the upper ends of said stan-
dards, and links connecting the blocks with the shaft, substantially as set forth.
Dated this 7th day of December 1897.
