Improvements in Churns.
1, SOLOMON WHITNEY of Manhattan, in the County of Riley and State of Kansas,
United States of America, Gentleman, do hereby declare the nature of this invention
to be as follows:-
:―
This my invention relates to certain new and useful in.provements in churns, and
which invention has for its object, to provide means whereby the cream is caused to
fall in a continuous stream from the top to the bottom of the churn, thus working it
all equally, and subjecting it to the action of the air in the churn which greatly
facilitates the production of butter.
In carrying out my invention, I provide within the churn a stationary dash or
scraper around which the cylinder of the churn revolves. This said stationary dash
or scraper consists of a flat blade of wood or other material, supported in the upper
part of the churn by suitable supports securely attached to a hollow and central shaft.
A suitable metal rod is adapted to pass through the aforesaid central shaft, and is
bent at one end into the form of a crank. This rod is supported in the side frames of
the churn. A wedge-shaped pin passing through the hollow shaft and the metal
rod passed therethrough serves to secure them together and prevent rotation of one
without the other. A pin passed through the cranked portion of the metal rod and
entering into the frame of the churn prevents the metal rod, hollow shaft and the
dash or scraper from revolving with the churn, which is rotated by a crank or other
simple device upon the stationary hollow shaft.

Improvements in Churns.
I, SOLOMON WHITNEY, of Manhattan, in the County of Riley and State of Kansas,
United States of America, Gentleman, 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 :-
This my invention relates to certain improvements in churns, having for its object
to simplify construction, to render fully effective the action of the dasher, and to
effect the adjustment of the dasher, so as to vary its angle of presentation to the cream
or contents of the vessel or receptacle, as may be desired, as also to utilize the
churn-body in the churning operation; and it consists of the detailed construction and
combination of parts, as will fully appear from the following description and
accompanying illustration.
The accompanying drawing represents a perspective view of my improved churn,
part being broken away to show the interior thereof.
In accordance with my invention I employ, preferably, a cylinder or churn-body A
of suitable capacity, which is provided at its ends or heads with hollow or tubular
shaft-extensions or journals a a which turn and are supported in the upper ends of
the central uprights or bearings of a base frame B, resting on the floor or ground.
One of the journals or shaft-extensions a a is provided with a handle for the rotation
of the cylinder or churn-body A.
is the dasher, which is provided with a tubular support or sleeve C, from which
project two arms (2, upon the outer ends of which is secured an angularly-disposed
blade suitably bevelled at its outer longitudinal edge to advantageously effect or cut
г

The dasher sleeve or support Crests at its ends in the journals or shaft-
extensions a a, and through it extends an axial rod D, which is connected to it by
key or wedge 6, inserted through an aperture in said sleeve or support and engaging
a coincident aperture or socket in said rod. One end of the rod D projects beyond
the inclosing shaft-extension or journal, and is there provided with an arm D¹ at
right angles therewith, the lower end of which has a knob c for its manipulation,
"while it carries directly above said knob an adjusting-pin d. A bar or arc E, having
a semi-circularly-arranged series of apertures e e, is secured to one of the uprights b
of the base frame or support B, so as to permit engagement with its apertures of the
adjusting-pin d, whereby the dasher is adapted to be adjusted so as to vary the angle
of presentation of its blade to the contents of the churn-body or cylinder, as may
desired. In effecting this adjustment the pin d is disengaged from one of the series
of apertures e e and engaged with another or the desired one thereof, according to
the angle it is desired to give the blade of the dasher. To the opposite end shaft-
extension or journal of the churn-body is applied a handle or crank for rotating the
latter, as practised in carrying on the churning operation.
G is the lid, which conforms to and closes an opening in the circumference of the
churn-body or cylinder A, through which the cream &c., is put into the latter, and
after churning is removed. This lid or cover is held removably in place by means of
keepers, secured to the body A at its edges having screws f¹ to secure the lid in
position.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what 1
claim is:
1. The combination, with the dasher having the hollow support or sleeve and means
for supporting the same, of the axial rod connected to said sleeve and having an arm
to vary the angle of presentation of the dasher, substantially as set forth.
2. The combination, with the dasher having a hollow support or sleeve, and means
for supporting the same, of the axial rod connected to said sleeve and having an arm
provided with an adjusting-pin, and the bar or are having a semi-circularly-arranged
series of apertures engaged by said adjusting-pin, substantially as and for the purpose
set forth.
