An Improvement in or relating to Churns.
ROBERT FRANCIS LOOSEMORE Tiverton Devon Solicitor do hereby declare the
nature of this invention to be as follows:—
An improvement in or relating to churns by the application to the working
thereof of a motive power machine actuated by the descending gravity of a weight
and to which is attached a governing apparatus to regulate its speed and velocity
of motion.

COMPLETE SPECIFICATION.
An Improvement in or relating to Churns.
I, ROBERT FRANCIS LOOSEMORE of Tiverton Devon Solicitor 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 an improvement in or relating to churns by the application
thereto of suitable mechanism as hereinafter described whereby the churn, (say of
the swinging type,) may be actuated automatically and without the continual
attention now required.
My improvements will be best understood by describing same with reference to
the accompanying drawings of which Figure 1 is a side clevation and Figure 2 a
plan of mechanism constructed according to my invention.
Mounted on framework or base A there is a drum B carrying a spur wheel C.
The spur wheel C gears with a pinion D, mounted on a shaft E. At the other end
of the shaft E is mounted loosely the spur wheel F which spur wheel F is clamped
when required to the shaft E by the clutch G. The spur wheel F gears with the
pinion H. Figure 1 which thus drives the shaft J, driving the wheel K, which may
either be a Hy wheel itself or communicate motion to a fly wheel L, through
pinion L', as shown on the drawings.
A rope or cord O, or its equivalent, is wound on the drum B and then passes
over a pulley situated in any convenient place and a weight N is attached to
the end of the rope, or a spring may be employed instead of the weight.
Or the pulley may be dispensed with and the weight allowed to descend direct
from the drum B.
There may be many convenient arrangements for arranging or supporting the
weight carrying pulley, for example when there is no other convenient provision for
carrying or supporting the sheeve pulley, a derrick or shears M may be used such
for example as is partially shown, but it is obvious that the pulley might be
suspended in any convenient manner so as to take advantage of the fall of the weight,
and that the greater the fall for the weight however arranged the longer the motion
of the machine would continue.
"
The weight N may be wound up by a handle placed on the square end of the
shaft E or by a differential wheel and axle, such as ** Weston's pulley block, and
there is also shown a ratchet and pawl R R arranged to prevent back motion.
P is a connecting rod mounted on the crank J', of the shaft J, for connecting the
swinging churn H with the motor, the latter and the churn, being arranged and
connected to the same base. The connecting rod P is shown as extending beneath
37

page_text: he churn, and is jointed to an arm II², depending downwards from the said
churn, but instead it may be connerted to the end of the churn next to the motor and
in an axial line with the body of the churn,
Qindicate a brake on the machine whereby the same may be stopped or allowed to
operate, as may be required. On winding up the drum the rope is coiled round
samo and the weight raised thereby to its highest point, the brake Q is then applied
and the machine is ready for work. As soon as the brake is release the rope, by
the weight, begins to descend and sets the whole train of wheels in motion, the
wheel K being thus caused to rotate quickly and to communicate an even recipro-
cating motion to the connecting rod Pand thus a corresponding motion to the
churn II, and so on so long as the weight continues to cause the drum B to slowly
revolve. The period of time that the churn is thus caused to oscillate is regulated
by the distance the weight has to travel and this may be regulated according to
situation and circumstances. When winding up the weight by the handle, which
for that purpose is placed on the shaft E, the clutch G is thrown out of gear with
the wheel and the pawl R is dropped into the teeth of the ratchet R. when the
weight N is wound the clutch is inserted in the wheel F and the pawl R³ pivotted
on the frame A is thrown up out of gear.
The mechanism constructed according to my invention is shown and described
as applied to a "cotswing” churn, because I have found it particularly applicable
for driving such a machine but it is also readily applicable to churns with circular
or other motion, as appears from the diagram view Figure 3 which is a plan of such
a churn illustrating my motor mechanism as applied thereto. This driving mechanism
is shown applied to the shaft J by means of the pulley S thereon.
Having now particularly described and ascertained the nature of my aid inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
First. The improved apparatus for churning substantially as hereinbefore described
and as shown in the accompanying drawings.
Second. In mechanism relating to or for driving churus the drum B with
weight on rope round drum, spur wheel C, pinion D, shaft E spur wheel F,
clutch ( pinion II, shaft J, spur wheel K and fly wheel, the shafi boing
connected to the churn H. by connecting rod 1 or equivalent conection whereby a
reciprocating or rotary motion is imparted to either churn marked II', all constructed
arranged and acting substantially as hereinbefore described and illustrated with
reference to the accompanying drawings.
Third. The combination in mechanism or machinery relating to churns of the
connecting rod, shown at P, or belt and pulley for connecting a churn, with a train
of wheels, driven by a drum, round which a rope passes, having a weight or its
equivalent at end of said rope, for communicating a reciprocating or rotary motion
to the said churn substantially as hereinbefore described and illustrated with
reference to the accompanying drawings.
