Improvements in and relating to Churns, Egg-beaters, and other
Mixing and Agitating Appliances or Machines.
We, BENJAMIN POPE BARTLETT, Surgeon, of Bourton, Dorsetshire, and EDWIN
PILLIP HARCOURT, Clerk, of Bourton, in the County of Dorset, do hereby declare
the nature of this invention to be as follows:-
This invention relates particularly to churns, but is equally applicable to egg-
beaters and other mixing and agitating appliances or machines, and has for its
objects more thoroughly disturbing or agitating the liquid, mass or substance
being operated upon than was heretofore possible with the present known
appliances or machines and further in the case of churns or butter making
machines a larger percentage of butter is obtained from a given quantity of cream
with a less expenditure of power and trouble and in less time than by any known
process or machine.
The present invention comprises essentially a suitably shaped receptacle adapted
to contain the liquid, mass or substance to be churned or operated upon and pro-
vided with a centrally disposed shaft or spindle, preferably in a vertical or hori-
zontal plane. This shaft or spindle is carried by suitable bearings mounted on
the receptacle or in the case where a vertical spindle is used-which is a pre-
ferential construction-it is carried in a long sleeve bearing mounted on the
lid or cover of the said receptacle.
The shaft or spindle is provided with two or more preferably three--dashers
or beaters which are carried by radial arms fixed on the central shaft or spindle
at unequal distances therefrom, so that when the central shaft or spindle is
rotated each dasher or beater has its own path of rotation. The dashers or beaters
may be arranged in the same vertical plane and parallel to the central spindle or
at an angle thereto, as found most efficacious.
The shaft or spindle is rotated in any convenient manner from any suitable
source of power but in the smaller size machines intended for domestic use,
preferably by means of a crank handle and suitable multiplying speed gear.

page_text: 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 invention relates particularly to churns, but is equally applicable to egg-
beaters and other mixing and agitating appliances or machines, and has for its
objects more thoroughly disturbing or agitating the liquid, mass or substance
being operated upon than was heretofore possible with the present known
appliances or machines, and further in the case of churns or butter making
machines a larger percentage of butter is obtained from a given quantity of cream
with a less expenditure of power and trouble and in less time than by any known
process or machine.
In the accompanying drawing which illustrates one method of carrying our
invention into practice. Figure 1 is a view in side elevation partly in section of
a hand power churn constructed according to this invention, and Figure 2 is a
transverse section thereof on line y-y of Figure 1.

Throughout both views similar parts are indicated by like letters of reference.
A suitably shaped receptacle X adapted to contain the liquid, mass or substance
to be churned or agitated is provided with a lid or cover . This lid or cover.
carries a frame A provided with a centrally disposed and vertically arranged sleeve
bearing a in which a vertical shaft or spindle B is free to rotate. Two or more
dashers or beaters C-preferably three as shown--are fixed to the central shaft or
spindle B at unequal distances therefrom by means of radial arms such as D, D',
so that when the shaft B is rotated each dasher or beater C has its own concentric
path of rotation.
The dashers or beaters C may be of any suitable description and arranged
at an angle to the central shaft or spindle B instead of parallel thereto as shown.
The shaft or spindle B is rotated in any convenient manner from any suitable
source of power but in the smaller size machines intended for domestic use, like
the one illustrated, it is preferably rotated by means of a crank handle E mounted
on an horizontal shaft F carried by bearings a¹ on the frame A, the shaft F
carrying a bevel spur wheel gearing with a bevel pinion on the shaft B.
It will be understood that the shaft or spindle carrying the dashers or beaters
may with slight variation be arranged in the horizontal plane instead of the
vertical one as illustrated.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is :-
(1) In a churn, eggbeater or other mixing and agitating appliance or machine,
the use of two or more beaters or dashers so arranged as to each have a separate
concentric path of rotation.
(2) A churn, eggbeater or other mixing and agitating appliance or machine
constructed arranged and adapted to operate substantially as hereinbefore des-
cribed and shown.
