Improved Driving-mechanism for Churns.
I, JOHN PITT BAYLY, of 18 Fulham Place. Paddington, in the County of.
London, Patent Agent, do hereby declare the nature of this invention (a com-
munication to me from abroad by JOHN JORDAN, and HENRY POTTER, of
Dee, Arkansas, U.S.A. Gentlemen,) to be as follows:-

This invention relates to churn-motors of that class known as
dashers," and to that particular construction thereof in which one dasher is
tubular and through which the opposite dasher is designed to reciprocate.
The objects of the invention are to reduce to a minimum the parts necessary
to the construction of the invention, and thus greatly simplify and cheapen the
completed apparatus.
side
Secured by brackets or straps to the lower end of the front standard is a platform, in
the under side of which is swiveled a supporting-caster, and upon its upper
is provided with a pair of opposite-curved keepers. The platform is designed
to support a churn body, which is retained in position by the keepers. The
caster strengthens the platform and facilitates the moving about of the motor.
Within a rear vertical slot is pivotally mounted a pair of vertically-opposite
levers, both of which project to the front, pass through, and terminate beyond the
front guide-slot of the front standard. Journalled in opposite bearings located
upon the side bars is a transverse power-shaft which is operated at one end by
a crank, and has mounted thereon between its bearings a large drive-pulley.
Below and in front of the bearings there is mounted upon the lower side bars a
pair of bearings in which is journalled a shaft, bent to form oppositely-disposed
cranks, each of which is connected with one of two levers by a pitian or con-
necting-rod. At one side of the cranks there is located upon the shaft a small
pulley, connected to and driven by the large drive-pulley by means of an endless
belt. The front end of the lower lever is slotted, and pivoted therein is a loosely
depending L-shaped bracket, which at its lower end is provided with an opening
into which projects a thumb-screw. A tubular dasher-shaft terminates at its upper
end in the opening portion by the screw, whereby it is suspended and adapted to
swing. The lower end of the tubular staff is provided with a dasher or disc. The
front end of the lever is also slotted, and removably pivoted therein is the upper
end of a dasher-staff, said staff passing through the tubular staff, terminating
below the same, and provided with a dasher or disc. A churn-body being placed
upon the platform, the pin is removed and the staff slid upwardly and the crank
turned until the dasher can be inserted into the churn-body, after which the staff
is again connected with the lever and the operation of churning may be com-
menced. By the oppositely-disposed cranks the levers will be simultaneously
vibrated in opposite directions at a rapid speed, and thus the cream will be
thoroughly agitated and quickly converted into butter.

Improved Driving-mechanism for Churns.
I, JOHN PITT BAYLY, of 18 Fulham Place, Paddington, in the County of
London, Patent Agent, do hereby declare the nature of this invention (a com-
munication to me from abroad by Joux JORDAN and HENRY POTTER, of
Dee, Arkansas, U.S.A. Gentlemen,) and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement :-
My invention relates to churn-motors of that class known as "double dashers,"
and to that particular construction thereof in which one dasher is designed to
reciprocate.
The cbjects of the invention are to reduce to a minimum the parts-necessary to
the construction of the invention, and thus greatly simplify and cheapen the com-
pleted apparatus.
With the above objects in view the invention consists in certain detail features
of construction hereinafter specified, and particularly pointed out in the claim.
Referring to the drawing, which is a perspective of a churn motor constructed
in accordance with my invention, A and A¹ designate, respectively, the front and
rear vertical standards of the motor-frame, the lower ends of which are spread and
shaped to form feet, and which at points-near their upper ends are somewhat
reduced and provided with guide-slots A³. Below their reductions the said
standards are connected-by-a-pair-of-opposite side bars B and near their lower ends
by a lower pair of side-bars-C
-Secured-by-brackets -or-straps.L_to_the_lower_end of the front standard is a
platform E, in the under side of which is swiveled a supporting-caster K, and
upon its upper side is provided with a pair of opposite-curved keepers J. The
platform is designed to support a churn-body, which is retained in position by the
keepers. The caster strengthens the platform and facilitates the moving about

shaft
دل
in opposite bearings e, located upon the side bars B, is a transverse-power-shaft.p..
which is operated at one end by a crank o, and has mounted thereon between its
bearings a large drive-pulley 'n. Below and in front of the bearings e there is
mounted upon the lower side bars C a pair of bearings, in which is journalled a
bent to form oppositely-disposed cranks h, each of which is connected
with one of the levers d'and d by a pitman or connecting-rod E. At one side of
the cranks there is located upon the shaft a small pulley Q, connected to and
driven by the large drive-pulley n by means of an endless belt j. The front end
of the lower lever d' is slotted, and pivoted therein is a loosely depending
-L-shaped bracket H, which at its lower end is provided with an opening 1, into
which projects a thumb-screw i. A tubular dasher-staff terminates-at-its-1
-upper-
end in the opening and is held in position by the screw, whereby it is
suspended and adapted to swing. The lower end of the tubular staff is provided
with a dasher or disc F. The front end of the lever d is also slotted, and
removably pivoted therein, as at s, is the upper end of the dasher-staff G, said
staff passing through the tubular staff, terminating below the same, and provided
with a dasher or disc t. A churn-body being placed upon the platform, the
pins is removed and the staff G slid upwardly and the crank turned until the
dasher F can be inserted into the churn-body, after which the staff G is again
connected with the lever d and the operation of churning may be commenced. By
the oppositely-disposed cranks h the levers d d will be simultaneously vibrated in
opposite directions at a rapid speed, and thus the cream thoroughly agitated and
quickly converted to butter..

page_text: 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 I
claim is:
In a churn-motor, the combination, with the front and rear standards, the upper
ends of which are slotted, as at A, and the upper and lower pairs of longitudinal
connecting-bars B and C, of the horizontal arms or levers i d', pivoted at their
rear ends in the slot of the rear standard, the drive-shaft, journalled in the upper
side bars, the crank o and pulley n, mounted thereon, the shaft g, journalled in the
lower pair of bars and provided with the oppositely-disposed cranks h, the pitman-
rods E, connecting each crank to a lever or arm d or d₁, the pulley Q, mounted on
the shaft, the belt connecting the same with the drive-pulley n, the platform
located in front of the front standard, the perforated L-shaped bracket H, pivotally
mounted in the front end of the arm d', the means for connecting said motor to the
device to be operated, substantially as specified.
