Year: 1853

page_text: LETTERS PATENT to William Steel, of Glasgow, in the County of
Lanark, North Britain, Brewer, for the Invention of "IMPROVE-
MONTO TAY MACISTEREDDY AD ADDADAMUTO BOD MAGING MAZ"
Sealed the 9th May 1854, and dated the 11th November 1853.
PROVISIONAL SPECIFICATION left by the said William Steel at
the Office of the Commissioners of Patents, with his Petition,
on the 11th November 1853.
I, WILLIAM STEEL, of Glasgow, in the County of Lanark, North
Britain, Brewer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN MACHINERY OR APPARATUS FOR MASHING MALT" to be
as follows:-
This Invention relates to an arrangement of machinery for the more
effectual mashing of malt in brewing and distilling operations. The
malt to.be mashed is primarily fed into an open hopper or receiver,

page_text: which has an adjustable passage at its lower end, opening into one end
of a slightly conical vessel or wooden chamber set horizontally, beneath.
As the unmashed malt descends through this passage it mingles with a
stream of hot water passed into the malt thoroughfare from a separate
pipe. The washing vessel is, carried on short brackets standing up
from the floor, and through its centre is passed a horizontal shaft
driven by pulleys at one end. On this shaft are set a series of mashing
or disintegrating arms standing out at right angles to the shaft's axis,
and as the shaft is made to revolve at a rapid rate the malt is thus well
mashed up and commingled with the hot water, and the mashed mass
is finally discharged' at the open smaller end of the vessel in a finished
condition.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Steel in the Great Seal Patent Office on
the 11th May 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
WILLIAM STEEL, of Glasgow, in the County of Lanark, North Britain,
Brewer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eleventh day of November, in the
year of our Lord One thousand eight hundred and fifty-three, in the
seventeenth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said William Steel, Her special licence
that I, the said William Steel, my executors, administrators, and
assigns, or such others as I, the said William Steel, my executors,
administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise,
and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS
IN MACHINERY OR APPARATUS FOR MASHING MALT," upon the condition
(amongst others) that I, the said William Steel, by an instrument in

page_text: writing under my hand and seal, should particularly describe and
ascertain the nature of the said Invention, and in what manner the
same was to be performed, and cause the same to be filed in the Great
Seal Patent Office within six calendar months next and immediately
after the date of the said Letters Patent.
NOW KNOW YE, that I, the said William Steel, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement thereof (that is to say):
My Invention consists in the use and employment of certain new
mechanical arrangements and combinations of parts constituting
improved machinery or apparatus for the more effectual mashing of
malt employed in brewing and distilling operations. And an important
feature in my said Invention consists in passing the malt and water
together through a cylindrical or conical shaped mashing vessel or
chamber, of wood or metal, which is distinct and separate from the.
mash tun. And I employ the aforesaid vessel or chamber for the
purpose of precipitating and securing all the volatile particles of
the malt. Whereas by the modes at present in use for mashing malt
the volatile particles thereof, or malt dust, escapes and is thereby lost.
And in order to explain my said Invention as completely as possible
I will now proceed to describe the best means I am acquainted with.
for carrying the same into practical effect, reference being had to the
illustrative Drawing hereunto annexed, and forming part of this my
Specification, and to the numeral figures and letters of reference marked
thereon respectively, as follows:
.
DESCRIPTION OF THE DRAWING.
Figure 1, is a side elevation of the machinery or apparatus which
I employ for mashing malt; Figure 2, is an end view thereof at A,,
in Figure 1; Figure 3, is an end view at B, in Figure 1; Figure 4, is
a longitudinal and vertical section taken through the lines C, D, in
Figures 2 and 3. At each of the foregoing Figures I employ similar
letters of reference to denote corresponding parts, in so far as such parts.
appear or can be seen at each of the Figures respectively. A, A, are

page_text: standards supporting the mashing vessel B, through the centre of which,.
and in the direction of the length thereof, a shaft C passes,
the same
being supported by bearings affixed to the ends D and E of the vessel.
B, as exhibited. The end D of said vessel is entirely closed and
rendered water-tight, and the end E is left open, as at Figure 3, for the
purpose of discharging the contents of the vessel. G, is a hopper, the
lower end whereof is securely fixed to the vessel B, and the upper end
of said hopper is open to receive the malt to be operated upon. H, is a
slide for regulating the quantity of malt discharged from the hopper into
the vessel B. I, is a pipe furnished with a cock K. for the admission of
hot water. It will be seen upon referring to Figures 3 and 4 that the
shaft C is furnished with a series of mashing or disintegrating arms"
L, L, which are securely fixed to said shaft at right angles, or nearly
so, to the axis thereof. M, is a pulley loose upon the shaft C; and N,
a pulley fixed thereon, over which a strap or band passes for imparting
rotary motion to said shaft. The operations of this apparatus are as
follows The slide H being closed, the hopper G is then charged
with unmashed malt; the cock K is then opened and allows a stream
of hot water to flow through the vessel B; the slide II is then drawn
back to the required extent, and the malt as it descends by its gravity
through the part g of the hopper is arrested by the stream of hot water,
and mingling therewith enters the vessel B, where it is operated upon
by the arms L, which, as the shaft revolves at a rapid rate, effects the
perfect mashing up and commingling of the malt with the hot water by
the time it has reached the opposite end of the vessel, where it is
discharged into the mash tun in a finished condition, and ready to
undergo the ordinary subsequent processes of conversion into beer or
spirit, as required.
Having thus described the nature of my said Invention of improve-
ments in machinery or apparatus for mashing malt, and in what manner
the same is to be and may be performed, I desire it to be distinctly
understood that I do not claim the exclusive use of any of the separate
parts above mentioned and referred to, except in so far as the same
may be employed in combination and for the purposes of my said
Invention, which I hereby declare to consist in, and I claim the use

page_text: and employment of, the above-mentioned novel apparatus in and for the
mashing of malt by operating thereen in a vessel, and with apparatus-
separate and distinct from the mash tun, as herein-before particularly
described, set forth, and represented by the illustrative Drawing
hereunto annexed.
In witness whereof, I, the said William Steel, have hereunto set
separate and distinct from the mash tun, as herein-before particularly
described, set forth, and represented by the illustrative Drawing
hereunto annexed.
In witness whereof, I, the said William Steel, have hereunto set
my hand and seal, this Twenty-fourth day of April, in the year
of our Lord One thousand eight hundred and fifty-four.
Witness,
WALTER SMART,
Rutherglen.
