IMPLOVEMENTS IN MINCING MACHINES
Year: 1869

page_text: LETTERS PATENT to William Burgess, of No. 96, Newgate Street, in
the City of London, for the Invention of "IMPLOVEMENTS IN MINCING
MACHINES."
Sealed the 6th July 1869, and dated the 22nd January 1869..
PROVISIONAL SPECIFICATION left by the said William Burgess at
the Office of the Commissioners of Patents, with his Petition, on
the 22nd January 1809.
I, WILLIAM BURGESS, of No. 06, Newgate Street, in the City of
London, do hereby declare the nature of the said Invention for "In-
PROVEMENTS IN MINCING MACHINES," to be as follows:-
This Invention has for its object improvements in mincing machines.
Mincing machines as ordinarily constructed are composed of a hollow
casing of cast iron made in two parts, which are connected together by
a hinge joint; through the casing are passed either one or two axes
carrying propelling screws or blades, which work with a cutting blade
or blades fixed to one-half of the casing. The interior surface of the
casing of such mincing machines has heretofore been coated either with

page_text: enamel or with enamel paint. Now according to this Invention I coat
the interior surface of the casing with tin. For this purpose I first coat
each of the two parts of the cast-iron casing with zinc by what is known
as the galvanizing process, and as the parts of the case are taken out of
the melted bath of zinc they are well shaken about to remove all super-
flous zinc, and to leave only a thin even coating upon the parts of the
case. The parts of the case are afterwards cleaned with acid and dipped
quickly into a bath of melted tin, and subsequently shaken or drained
i: hot grease to remove excess of metal. The propelling screw or blades
carried by the axes may also be similarly coated with tin.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Burgess in the Great Seal Patent Office
on the 22nd July 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
BI RGESS, of 96, Newgate Street, in the City of London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Tatters Patent, bearing date the Twenty-second day of January, in the
year of our Lord One thousand eight hundred and sixty-nine, in the
thirty-second year of Her reign, did, for Herself, Her heirs and succes-
sors, give and grant unto me, the said William Burgess, Her special
licence that I, the said William Burgess, my executors, administrators,
und assigns, or such others as I, the said William Burgess, 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
MINCING MACHINES," upon the condition (amongst others) that I, the
Said William Burgess, my executors or administrators, by an instru-
ment in writing under my, or their, or one of their hands and scals,
should particularly describe and ascertain the nature of the said Inven-
tion, 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
Patrat.

page_text: NOW KNOW YE, that I, the said William Burgess, do hereby declare
the nature of 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 :-
This Invention has for its object improvements in mincing machines..
Mincing machines as ordinarily constructed are composed of a hollow
casing of cast iron made in two parts, which are connected together by a
hinge joint; through the casing are passed either one or two axes
carrying propelling screws or blades, which work with a cutting blade
or blades fixed to one-half of the casing. The interior surface of the
casing of such mincing machines has heretofore been coated either with
enamel or with enamel paint. Now according to this Invention I cont
the interior surface of the casing with tin. For this purpose I first cont
each of the two parts of the cast-iron casing with zinc by what is
known as the galvanizing process, and as the parts of the case are taken
out of the melted bath of zinc they are well shaken about to remove all
superfluous zinc, and to leave only a thin even coating upon the parts
of the case. The parts of the case are afterwards cleaned with neid, by
preference hydrochloric acid; they are dried and dipped quickly into a
bath of melted tin, when they are allowed to remain only just so long as
is required for the metal to tako upon the surface. The articles are
taken from the tin bath and shaken or by preference drained for a few
moments in hot grease to remove the excess of metal. The propelling
screw or blades carried by the axes may also be similarly coated with
tin.
tin.
In witness whereof, I, the said William Burgess, have hereunto set
my hand and seal, this Twenty-first day of July, in the year of
our Lord One thousand eight hundred and sixty-nine.
