PROVISIONAL SPECIFICATION.
A New or Improved Churn.
I, JOHN HOSKIN PETT of 41 Fore Street, Redruth Cornwall Engineer do
hereby declare the nature of this invention to be as follows:-
My invention relates to a new or improved churn and consists of peculiar
mechanism arranged within a tub or vat for the purpose of agitating the milk and
convert it into butter.
In carrying my invention into practice I provide a frame of iron or other suitable
material the ends of which are fixed to each side of the tub or vat by means of
suitable sockets screwed or otherwise secured to these sides.
This frame extends over and across the tub or vat and carries at its centre a
vertical shaft provided with a curved blade and surmounted by a horizontal bevil
wheel gearing with a similar vertical wheel mounted upon a horizontal shaft
suspended at its inner end i.e. the end carrying the bevil wheel by means of a
support bolted to the frame above mentioned. The other or outer end of this
horizontal shaft passes through one side of the frame and carries a fly wheel
furnished with a crank handle.
Upon the vertical shaft are mounted four arms of various length and to three of
the latter are screwed three propellers preferably of stoneware extending nearly to
the bottom of the tub or vat, while the fourth arm carries a curved blade which
revolves against the side of the said tub or vat.
As my improvements are capable of some modifications without departing from
the principle thereof I do not restrict myself to materials, dimensions, or to the
precise form or placement of the several parts thereof.

A New or Improved Churn.
1, JOHN HOSKIN PETT of 41 Fore Street, Redruth, Cornwall, Engineer, 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 a new or improved churn, and consists of peculiar
mechanism arranged within a tub or vat for the purpose of agitating the cream and
convert it into butter. In carrying my invention into practice I provide a frame of
iron or other suitable material, the ends of which are fixed to each side of the tub
or vat by means of suitable sockets screwed or otherwise secured to these sides.
This frame extends over and across the tub or vat, and carries at its centre a
vertical shaft provided with a curved blade and surmounted by a horizontal bevel
wheel gearing with a similar vertical wheel mounted upon a horizontal shaft
suspended at its inner end i.e. the end carrying the bevel wheel by means of a
support bolted to the frame above mentioned. The other or outer end of this
horizontal shaft passes through one side of the frame and carries a fly wheel
furnished with a crank handle.
Upon the vertifical shaft are mounted four arms of various length and to three
of the latter are secured three propellers of metal or other material but preferably

page_text: of stone ware, extending nearly to the bottom of the tub or vat, while the fourth arm
carries a curved blade which revolves against the side of the said tub or vat.

a is the tub supported by a stand b, of wood or other suitable material. The
tub a is furnished with sockets into which are secured by means of screws, the
vertical ends of a rectangular frame d extending over and across the said tub as
clearly shown in Fig. 2. To this frame is centrally secured in a boss formed
thereon, the upper end of a vertical shaft, furnished with a curved blade, and
carrying a horizontal bevel wheel g, gearing with a similar vertical wheel h, which
is mounted on a horizontal shaft, passing through another boss formed in one of
the vertical sides of the frame aforesaid, and carrying at its outer end a fly wheel,
furnished with a handle k, the inner end of this shaft being supported by a hanging
bearing, bolted to the frame d.
Upon the vertical shalt are mounted four arms mm² m² m² of various lengths as
clearly shown in Fig. 3, to the arms m² m² m² are screwed three propellers n, n', n²,
preferably of stone ware extending nearly to the bottom of the tub or vat a. The
arm is provided with a blade o, curved in the manner shown in Fig. 4 and
revolving against the side of the said tub or vat.
As the wheel j, is turned by means of the handle &, the bevil wheel h, is set in
motion, and with it the wheel, imparting a rotary motion to the shaft, the blade,
the propellers n, n², a², and the blade e, which churns the cream previously placed
in the tub a.
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 :-
My improved churn for making butter arranged constructed and operating
substantially as herein described and shown.
