AN IMPROVED METHOD
Year: 1858

page_text: LETTERS PATENT to William Littell Tizard, of Mark Lanc, in the City of
London, Brewers' Engineer, for the Invention of "AN IMPROVED METHOD
Sealed the 21st December 1858, and dated the 26th June 1858.
PROVISIONAL SPECIFICATION left by the said William Littell Tizard at
the Office of the Commissioners of Patents, with his Petition, on the
26th June 1858.
I, WILLIAM LITTELL TIZARD, of Mark Lane, in the City of London,
Brewers' Engineer, do hereby declare the nature of the said Invention for
"AN IMPROVED METHOD OF TREATING BREWERS' AND DISTILLERS' MALT OR GRIST,"
to be as follows:-
My Invention consists in subjecting malt or grist after it has undergone the
usual processes of grinding and saturating with water, to trituration or
mastication. This may be effected in a variety of ways well known to
mechanics; for example, a series of open floors or discs may be made (of
either wire gauze, or wire cloth, wood, or metal,) to occupy nearly one half of
the diameter of, say, a mash tun or vessel, each fixed to a frame carried round
the central shaft of the mashing gear. On each floor is placed a similar disc,
a shaft passes through each of the latter, and on motion being communicated
to the shaft, the upper discs revolve on the floors, macerating the grain or

page_text: grist that interposes between their surfaces. A similar effect may be produced
on the grist by rollers, or rollers with friction boards between, a vibrating
motion being imparted to the latter as they move through the mash. Indeed,
the wet grist or mash may be intercepted, rubbed, squeezed, and reduced in
a countless number of ways; hence it is that I do not limit myself to the use
of any particular triturating machine, neither do I confine my masticating
operation to the interior of the mash tun, as nothing is easier (if desirable)
than to withdraw the wet grist from the tun, rub, or macerate it in an
apparatus on its exterior, and return such reduced grist or grain to the mash
tun, to be operated on by either the attemperator and sparger, or both.
The following arrangement may be preferred by some operators:-Let the
ground grist hopper be made water-tight, and place a macerating apparatus
beneath it, so as to command the mash tun. Steep the grist in the hopper,
and let it gravitate through the macerator into the mash tun or other
receptacle, to be further operated on. The immediate consequences of this
trituration or mastication of brewers' and distillers' grist are to convert the
whole or nearly the whole of the farinaceous matter, together with the hordein
(hitherto considered inconvertible), into valuable wort or wash.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Littell Tizard in the Great Seal Patent Office on the
24th December 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
LITTELL TIZARD, of Mark Lane, in the City of London, Brewers' Engineer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-sixth day of June, in the year of our Lord
One thousand eight hundred and fifty-eight, in the twenty-second year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said William Littell Tizard, Her special licence that I, the said
William Littell Tizard, my executors, administrators, and assigns, or such
others as I, the said William Littell Tizard, 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 Inven-

page_text: tion for "AN IMPROVED METHOD OF TREATING BREWERS' AND DISTILLERS' MALT OR
GRIST," upon the condition (amongst others) that I, the said William Littell
Tizard, my executors or administrators, by an instrument in writing under
my, or their, or one of their hands and seals, 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 Littell Tizard, do hereby
declare the nature of my 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 subjecting malt or grist, after it has undergone
the usual processes of grinding and saturating with water, to trituration or
mastication. This may be effected in a variety of ways well known to
mechanics; for example, a series of open floors or discs may be made (of
either wire gauze, or wire cloth, wood, or metal,) to occupy nearly one half of
the diameter of, say, a mash tun or vessel, each fixed to a frame carried round
the central shaft of the mashing gear. On each floor is placed a similar disc,
a shaft passes through each of the latter, and on motion being communicated
to the shaft, the upper discs revolve on the floors, macerating the grain or grist
between their surfaces. A similar effect may be produced on the grist by
rollers, or rollers with friction boards between, a vibrating motion being
imparted to the latter as they move through the mash. Indeed, the wet grist
or mash may be intercepted, rubbed, squeezed, and reduced by various means;
hence I do not limit myself to the use of any particular triturating machine,
neither do I confine my masticating operation to the interior of the mash tun;
as the wet grist may be easily withdrawn from the tun, and rubbed or
macerated in a separate apparatus, and then returned reduced to the mash
tun, to be operated on by either the attemperator or sparger, or both.
Again, the following arrangement may be followed:-Let the ground grist
hopper be made water-tight, and place a macerating apparatus beneath it, so
as to command the mash tun. Steep, the grist in the hopper, and let it
gravitate through the macerator into the mash tun or other receptacle to be
further operated on. The immediate consequences of this trituration or
mastication of brewers' and distillers' grist are to convert the whole or nearly
the whole of the farinaceous matter, together with the hordein (hitherto con-
sidered inconvertible), into valuable wort or wash.

page_text: And having now described the nature of my said Invention, and in what
manner the same may be performed, I declare that I claim, subjecting malt
or grist, after it has undergone the usual processes of grinding and saturating
with water, to trituration or mastication.
In witness whereof, I, the said William Littell Tizard, have hereunto
set my hand and seal, this Twenty-third day of December, One
thousand eight hundred and fifty-eight.
