A METHOD FOR THE MAKING IMPE- RIAL BARREL CHURNS
Year: 1777

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
RASTRICK, of Morpeth, in the County of Northumberland, Engineer, send
greeting.
WHEREAS His most Excellent Majesty King George the Third, by His
Letters Patent under the Great Seal of Great Britain, bearing date at West-.
minster, the Eighth day of August, in the seventeenth year of His reign, did
give and grant unto me His especial licence that I, the said John Rastrick,
during the term of fourteen years therein mentioned, should and lawfully
might make, use, exercise, and vend, within that part of His said Majesty's
Kingdom of Great Britain called England, His Dominion of Wales, and Town
of Berwick-upon-Tweed, my Invention of "A METHOD FOR THE MAKING IMPE-
RIAL BARREL CHURNS;" in which said Letters Patent there is contained a pro-
viso obliging me, under my hand and seal, particularly to describe and ascertain
the nature of the said Invention, and in what manner the same is to be per-
formed, and to cause the same to be inrolled in His Majesty's High Court of
Chancery within four calendar months next and immediately after the date of
the said Letters Patent, as in and by the same, relation being thereunto had,
will more fully appear.
NOW KNOW YE, that I, the said John Rastrick, in complyance with the
said proviso, do hereby declare that my said Invention for the Making of Im-
perial Barrel Churns, is performed in the following manner, that is to say :-
The basis is a single or double barrel cask or vessell, either hanging, hori-
zontal, standing, perpendicular, or inclining, put upon or without frame. The
barrel may be made of timber, tin, or metal, so that the breakers or internal

page_text: works turn round within by a handle without, put upon the end of an iron
axis, or worked by a wheel and pinion. The iron axis passes through a coller
on the end of the barrel, from thence through a wooden axis into another
coller or footstep. The iron axis has a stop to prevent the cream from running
out at the celler. The stop is an iron ring, fixt on the iron axis, running
against the end of the barrel, or otherwise. The stopper may be made of any
other metal or leather. The wooden axis is divided into three divisions, more or
less, according to the size of the barrel; and in each division there are arms or
spoaks fixt into the wooden axis for breakers, with a rail put upon the ends of
each sett of breakers. The rail may be either solid, holed through, or indented
on the edge. The coller is an iron socket with a plate fixed on the end of the
barrel. These collers may be made of metal or wood, and generally hangs
upon a frame, so the barrell can be turned round independant of the breakers
or internal works, or fixed fast at pleasure. There is a ventilator put upon
the side or end of the barrel to convey in the sweet air, and extract the acid
from the cream. The said ventilator is a box of wood with a partition in the
same, with an angler peace at the bottom for receiving and discharging the
air. It may be worked with valves, or conveyed with pipes from or into the
barrel at different places. The ends of the barrel may either be made fast, or
to take out occasionally with screws.
In witness whereof, I, the said John Rastrick, have hereunto set my
hand and seal, this Twenty-ninth day of November, in the year of
thousand coron hundred and coventy-sovan
JOHN RASTRICK. (L.B.).
