Year: 1852

page_text: LETTERS PATENT to John Gilbert, of 79, Wardour Street, and
Samuel Nye, of the same place, in the County of Middlesex,
for the Invention of "IMPROVEMENTS IN MINCING MEAT AND OTHER
SUBSTANCES "
Sealed the 12th January 1853, and dated the 20th October 1852.
PROVISIONAL SPECIFICATION left by the said John Gilbert and
Samuel Nye at the Office of the Commissioners of Patents, with
their Petition, on the 20th October 1852.
We, JOHN GILBERT, of 79, Wardour Street, and SAMUEL NYE, of the
same place, in the County of Middlesex, do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN MINCING MEAT AND OTHER
SUBSTANCES" to be as follows:-
The other end of
This Invention consists of a fixed metal cylinder, having one of its
ends provided with a series of curved or bent concentric knives or
blades, which are fixed therein when in use, but capable of being
removed when to be sharpened or otherwise.
the cylinder is caused to revolve, and is provided with a series of
projections, set or affixed in curved directions from the centre, which
force the meat and other substances against the edges of the curved
Price 8.1

page_text: knives, and progressively move the substances towards the centre, where
they are forced out thro' a suitable orifice or opening. The meat is fed
in by a hopper at the periphery of the cylinder.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Gilbert and Samuel Nye in the Great
Seal Patent Office, on the 20th April 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we,
JOHN GILBERT, of 79, Wardour Street, and SAMUEL NYE, of the same
place, in the County of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Hor
Letters Patent, bearing date the Twentieth day of October, in the year
of our Lord One thousand eight hundred and fifty-two, in the six-
teenth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said John Gilbert and Samuel Nye, Her
special licence that we, the said John Gilbert and Samuel Nye,
our executors, administrators, and assigns, or such others as we, the
said John Gilbert and Samuel Nye, our 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 APPARATUS FOR
MINCING MEAT AND OTHER SUBSTANCES," upon the condition (amongst
others) that we, the said John Gilbert and Samuel Nye, or one of us,
by an instrument in writing under our hands and seals, or under the
hand and seal of one of us, should particularly describe and ascertain
the nature of our 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 we, the said John Gilbert and Samuel Nye,
do hereby declare the nature of our 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):

page_text: This Invention consists of a fixed metal cylinder, having one of its
ends provided with a series of curved or bent concentric knives or.
blades, which are fixed therein when in use, but capable of being
removed when to be sharpened or otherwise. The other end of the.
cylinder is caused to revolve, and is provided with a series of projec-
tions, set or affixed in curved directions from the centre, which force
the meat and other substances against the edges of the curved knives,
and progressively move the substances towards the centre; where they
are forced out through a suitable orifice or opening. The meat is fed-
in by a hopper at the periphery of the cylinder. And in order that.our
said Invention may be more fully understood, and readily carried:.into
effect, we will proceed to describe the means pursued by us.
Figure
shows an interior view of one arrangement of the appa-
ratus, the moveable revolving end of the cylinder removed; Figure 2,
shows an interior view of the moveablo revolving end of the cylinder
provided with a series of projections which force the meat and substances
against the knives or blades; Figure 3, shows a side view of the
machine complete; and Figure 4, shows the flanged ring which is fixed
to one end of the cylinder, by means of which the moveable end of the
cylinder is retained in its place and yet allowed to turn. The machine
is so arranged that the neat and substances to be minced is caused to
be fed into the machine through a hopper at the periphery of the
machine and near one end of it, and the materials as they are minced
are forced through at an opening in the centre of the fixed end of the
fixed cylinder. a, is a fixed cylinder, having at one end thereof a series of
blades b, b, which are wedged tightly together between the filling pieces
, by means of the set screw c¹, when in use; but when it is desired to
remove them for the purpose of sharpening, the screw c¹, is turned back,
which will free the blades and allow of their being removed; f, is the
outlet in the centre of the fixed end 7, of the cylinder, through which
the minced meat and substances are forced; h is the hopper on the
periphery of the cylinder, into which the meat and substances to be
minced are placed; i, is the moveable end of the cylinder, and which
is retained in its place by the ring j. This moveable end i, is caused

page_text: to rotate by the handle k, and by reason of having projections around
the axis of motion the meat and other matters are moved and forced
against the blades b. Figure 5, shows a section of another machine,
differing in some particulars from the preceding machine, but in regard
to the peculiarity of the action it is the same. The cylinder a, is fixed,
and it has a series of knives b, projecting into it, and they are fixed by the
filling pieces or wedges c, in the recess e. The meat or substance as it is
cut is forced towards the fixed end of the cylinder, and is forced through
an opening in the centre of that end in like manner to the previous
machine. And the chief difference between this machine and that first
described: is, that the fixed cylinder is longer, and in this present machine
the projecting instrument which forces the meat and substances. between
the cutter is formed on or fixed to a projecting axis carried by the
moveable end i, of the cylinder as shown, but the moveable end i, and
the means of giving motion, remain the same. And we would state
that we make no claim to a series of projections around an axis where
such axis is supported in bearings at each end of the machine. We
would remark, that in both machines that the end i, of the cylinder a,
rotates, and carries with it the forcing or projecting instruments which
force the meat or substances between the knives.
Having thus described the naturo of the Invention, and the manner
of performing the same, we would have it understood that what we
claim is, the mode of combining the parts herein explained.
In witness whereof, we, the said John Gilbert and Samuel Nye,
have hereunto set our hands and seals, this Nineteenth day of
April, in the year of our Lord One thousand eight hundred and
fifty-three.
Witness,
S. CARPMAEL.
