Sealed the 19th December 1862, and dated the 25th June 1862.
PROVISIONAL SPECIFICATION left by the said George Turner at the
Office of the Commissioners of Patents, with his Petition, on the
25th June 1862.
I, GEORGE TURNER, of 13, Rose Terrace, Brompton; in the County of
Middlesex, Machinist, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN MINCING APPARATUS, SUCH IMPROVEMENTS BEING. ALSO
APPLICABLE TO MACHINES FOR GRINDING COFFEE AND SPICES," to be as follows:-
This Invention relates to machines. for mincing meat and vegetables, and is.
also applicable to machines for grinding coffee and spices, and consists in the
application to such machines of a moveable end plate for forming a second
bearing for the spindle of mincing machines of the ordinary construction, such
plate being secured in its place by means of two screws or pins, one of which.
is inserted in the upper part of the casing of the machine and the other in the
lower part of such casing, slots being formed in the moveable end plate for
the purpose of embracing such-screws or. pins. An aperture is made in the
moveable end-plate to allow of the exit of the minced material as it is forced
out of the machine, by the, action of blades formed on the revolving spindle,

page_text: which is in the ordinary way. Mills, for grinding coffee and spices may be
furnished with a similar end plate, such end plate being provided with a screw
for the purpose of adjusting the conical cutter employed in such mills for
regulating the fineness of the cut.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said George Turner in the Great Seal Patent Office on the
24th December 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
TURNER, of 13, Rose Terrace, Brompton, in the County of Middlesex,
Machinist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fifth day, of June, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-sixth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me the
said George Turner, Her special licence, that I, the said George Turner, my
executors, administrators, and assigns, or such others as I, the said George
Turner, 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 APPA-
RATUS, SUCH IMPROVEMENTS BEING ALSO APPLICABLE TO MACHINES FOR GRINDING
COFFEE AND SPICES," upon the condition (amongst others) that I, the said
George Turner, 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.
A
NOW KNOW YE, that I, the said George Turner, do hereby declare the
nature of the said Invention, and in what. manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say :-
This Invention relates to machines for mincing meat and vegetables, and is
also applicable to machines for grinding coffee and spices, and consists in the s
application to such machines of a moveable end plate for forming a second

page_text: bearing for the spindle of mincing machines of the ordinary construction, such
plate being secured in its place by means of two screws or pins, one of which
is inserted in the upper part of the casing of the machine and the other in the
lower part of such casing, slots being formed in the moveable end plate for
the purpose of embracing such screws or pins. An aperture is made in the
moveable end plate to allow of the exit of the minced material as it is forced
out of the machine by the action of blades formed on the revolving spindle;
which is in the ordinary way. Mills for grinding coffee and spices may lie
furnished with a similar end plate, such end plate being provided with a screw
for the purpose of adjusting the conical cutter employed in such mills for
regulating the fineness of the cut.
And in order that my said Invention may be most fully understood and
readily carried into effect I will proceed to describe the Drawings hereunto
annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a side view, Figure 2 a vertical. section, and Figure 3 a front
view of mincing apparatus constructed according to my Invention.
It consists of two metal castings a and b hinged together at c. The lower
casting a is arranged so that it can readily be secured to a table or board by a
clamp, screws, or otherwise, and it is fitted with knives a', a'; they may be
cast together in lead or spaced with filling pieces to form the set, and this is
locked tightly in the recess forined for it in the casting by the screw a². The
upper part b is formed with a hopper, by which the material is fed into the
apparatus; d is a latch to hold the parts a and b together in position for use.
These parts form a barrel in which the propeller e works; it consists of an
axis with a crank handle at one end and with a series of curved arms mounted
upon it. These arins are arranged in a spiral direction around the axis, and
are, by preference, of galvanized iron; the bearing for the axis, at the end
near the handle, is bored in the pieces a and b, half in each. The further
end of the axis has its bearing in a moveable end plate f; this is held in its
place, when the apparatus is set up for use, by the two screws or pins g. 9,
one inserted in the upper and the other in the lower casting. These screws
or pins enter slots or notches in the end plate and thus retain it. The end
plate has also a hole in it for the escape of the material when minced.
Two forms which this end plate may take are shown at Figures 4 and 5;
that shown at Figures. 4 is suitable for mincing suet and similar purposes; that
shown at Figures 5 is suitable for use when it is. required that the minced
material should be filled into skins, as in making sausages.

page_text: It will be seen that by loosening the latch d the barrel of the apparatus
may be opened and the propeller and the end plate removed, so that they may
be easily and thoroughly cleaned., As before mentioned, mills for grinding
coffee and spices may be similarly made with a moveable end plate having a
bearing in it for the end of the spindle. The barrel of the mill is conveniently
made, in a similar manner to that already described, with two castings hinged
together, but it is made conical interiorly and with teeth upon it, as is usual in
mills; the barrel I in this case arrange vertically. The axis has the ordinary
conical cutter of a mill upon it, and it has its end bearing in an end plate,
such as already described, except that it carries a screw on which the end of
the axis of the conical cutter rests, so that by turning this screw the distance
between the teeth on the conical cutter and the, teeth in the barrel can be
adjusted.
Having thus described the nature of my Invention, and the manner of per-
forming the same, I would have it understood that what I claim is, the
constructing mincing apparatus with a moveable end plate for forming a
second: bearing for the spindle, and also the manner of securing the said end
plate; I also claim constructing coffee and spice mills with a similar, moveable
end plate.
In witness whereof, I, the said George Turner, have hereunto set my
hand and seal, this Thirteenth day of November, in the year of our
Lord One thousand eight hundred and sixty-two.
GEORGE TURNER. (L.S.)
