INVENTED MASHING MACHINE
Year: 1810

page_text: ROBINSON'S SPECIFICATION.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
ROBINSON, of Roberts Bridge, in the Parish of Salehurst, in the County
Sussex, Brewer, send greeting.
WHEREAS His present Majesty King George the Third, in and by
His Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Twelfth day of March last, for Himself, His heirs and
successors, did give and grant unto me, the said Thomas Robinson, His
special licence, full power, sole privilege and authority, that I, the said
Thomas Robinson, my executors, administrators, and assigns, and every of
them, by myself and themselves, or by my and their deputy or deputies,
servants or agents, or such others as I, the said Thomas Robinson, my
executors, administrators, or assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term of years
therein mentioned, and then to come and unexpired, should and lawfully
might make, use, exercise, and vend, within England, Wales, and the Town
of Berwick-upon-Tweed, my "INVENTED MASHING MACHINE;" in which said
Letters Patent there is contained a proviso, obliging me, the said Thomas
Robinson, by an instrument in writing under my hand and seal, particularly to
describe and ascertain the nature of my said Invention, and in what manner the
same is to be performed, and to cause the same to be inrolled in His Majesty's
High Court of Chancery within two calendar months next and immediately
after the date of the said recited Letters Patent, as in and by the same,
reference being thereunto had, will more fully appear.
NOW KNOW YE, that in compliance with the said proviso, I, the
said Thomas Robinson, do hereby declare that my said Invention is fully
ascertained by the Drawing hereunto annexed, and the following description
thereof, viz:-

page_text: The Drawing, Fig. 1st, hereunto annexed, represents a mashing machine on
my newly invented construction, in the centre of which is an upright shaft, as
at A in the annexed Plan, on which is fixed a wheel No. 2, moved by another
marked No. 1, connected by a shaft with the horse wheel, or turned by means
of steam, wind, or water; from this shaft projects a beam B, one end of which
turns loosely on a collar on the shaft A, the other end runs on the edge of the
tub on two small rollers H, one fixed on each side of the said beam; on the
upright shaft A is a wheel 3, which, communicating with the wheel 4, turns
the agitator or stirrer 10, composed of an upright spindle, in which are inserted
vanes or blades of iron, the upper part of which works in a box through the
centre of the beam B, the bottom through the beam or bar of iron C; one
end of the said bar C works in a collar near the bottom of the shaft at I, the
other near the outside of the tub, where it is suspended by a spronk or forked
bar, the upper ends of which are screwed on each side the arm B; on the
top of the agitator or spindle 10 is a wheel 5, communicating with another 6,
which turns the agitator 11 on the spindle, of which there is a pinion 8,
turning the wheel 9, and that, working in teeth fixed round the inside of the
tub, carries the machine forward, whereby the whole of the goods are moved
and the liquor completely blended therewith. In a tub not exceeding thirty
quarters the machine may be easily worked by one man, turning the winch G
in nearly as short a time as if done by a horse, which requires from fifteen to
twenty minutes. The structure of this machine is such it can be worked with
great facility in an oval tub by means of the shaft A, Fig. 2nd, being formed
crank wise, and a pinion placed between the wheels 5 and 6, whoreby the
machine and the shaft A, Fig. 2nd, will work in contrary directions, and
give it the necessary elliptic motion. Where the tub is of small diameter, the
machine may not require more than one agitator, but if large it may be
necessary to have two, three, or four. The agitators or stirrers of this
machine working horizontally do not expose the goods or liquor to the atmos-
phere, whereby they might be cooled; the proper degree of heat therefore
being retained dissolves the saccharine and other valuable properties of the
malt in the most effectual manner.
In witness whereof, I, the said Thomas Robinson, have hereunto set my
hand and seal, this Ninth day of May, One thousand eight hundred
Sealed and delivered in the presence of
THOMAS (L.s.) ROBINSON.
EDWP PLOMER.
THO WALTERS.
