PROVISIONAL SPECIFICATION left by the said Joseph Donnell at the
Office of the Commissioners of Patents, with his Petition, on the 23rd
September 1865.
I, JOSEPH DONNELL, of Liverpool, in the County of Lancaster, Merchant,
do hereby declare. the nature of the said Invention for "CERTAIN IMPROVE.
MENTS IN MACHINERY FOR CUTTING OR MINCING MEAT AND STUPPING THE SAME INTO
SKINS OR INTESTINES FOR FORMING SAUSAGES," to be as follows:-
I employ a horizontal cylinder made of two half pieces hinged together, so
that the cylinder may be opened when necessary, or closed and latched or
clamped together. Upon the top half of the cylinder is a hopper or opening,
through which the meat is entered. Passing through the cylinder is a shaft,
upon the outer end of which is a crank wheel or pulley, by which it is to be

page_text: rotated by power or hand. This shaft is formed with a feeding spiral blade
inside the cylinder below the hopper, and further along on the shaft arecutters
arranged in a spiral position, but each cutter is formed of a blade of metal set
at right angles to the shaft with a curved cutting edge, and within and
attached to the cylinder similarly shaped stationary cutters are fitted. The
set of cutters revolved by and with the shaft act like shears against the said
stationary cutters to cut up and mince the meat. At the delivery end of the
cylinder is a stationary plate of sheet metal perforated with holes, that detain
any pieces of meat that are too large to pass through them, and on each side
of this plate there are cutters the same as aforesaid, that cut off the pieces of
meat that otherwise might fill up the holes.
From the end of the aforesaid meat mincer or cutter the meat falls.
saway
immediately into the sausage stuffer, or may be received in any vessel
and afterwards placed in the stuffer. This stuffer is formed as a vertical
hopper, in the lower part of which is a cylinder rotated by a crank on its
shaft; this cylinder is formed with slots parallel to its axes, and in which slots
are plates with projections at their ends running in excentric grooves in the
metal at the ends of the cylinder. The cylinder touches the hopper on one
side, but is some distance therefrom on the other, and a nozzle is provided at
one side of the hopper lower down than the cylinder, and upon this nozzle the
intestine or skin is drawn. The cylinder and its plates act like a rotary pump
and take the meat from the hopper and force it out of the nozzle into the bag,
skin, or intestine extending from the nozzle, the meat running from the
nozzle with a continuous and rapid movement.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Joseph Donnell in the Great Seal Patent Office on the
16th March 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
DONNELL, of Liverpool, in the County of Lancaster, Merchant, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-third day of September, in the year of our
Lord One thousand eight hundred and sixty-five, in the twenty-ninth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Joseph Donnell, Her special license that I, the said Joseph Donnell,
my executors, administrators, and assigns, or such others as I, the said Joseph
Donnell, my executors, administrators, and assigns, should at any time agree

page_text: th, and no others, from time to time and at all times thereafter during the
rm therein expressed, should and lawfully might make, use, exercise, and
nd, within the United Kingdom of Great Britain and Ireland, the Channel
lands, and Isle of Man, an Invention for "CERTAIN IMPROVEMENTS IN
ACHINERY FOR CUTTING OR MINCING MEAT AND STUFFING THE SAME INTO SKINS OR
TESTINES FOR FORMING SAUSAGES," (a communication to him from abroad by
arches Miles, of the City of New York, United States of America,) upon the
ndition (amongst others) that I, the said Joseph Donnell, by an instrument
writing under my hand and seal, should particularly describe and ascertain
e nature of the said Invention, and in what manner the same was to be
rformed, and cause the same to be filed in the Great Seal Patent Office
thin six calendar months next and immediately after the date of the said
etters Patent.
NOW KNOW YE, that I, the said Joseph Donnell, do hereby declare the
ture of the said Invention, and in what manner the same is to be per-
rmed, to be particularly described and ascertained in and by the following
atement, reference being had to the Drawing hereunto annexed, and to the
tters and figures marked thereon (that is to say) :-
Fig. 1 is a perspective view of the mincing machine adapted to being
driven by a belt to an engine or shafting;

4 is a detached view of the perforated detaining plate and clearers;
5 is a cross section; and
6 is a longitudinal section of the apparatus employed in stuffing skins
or intestines to form sausages; and
Fig. 7 is one of the propelling blades of the stuffer detached.
A horizontal cylinder is employed made of two half pieces B, B, hinged
gether, so that the cylinder may be opened when necessary, as seen in
g. 1, or closed and latched by latches Tcr clamped together. Upon the
p half of the cylinder is a hopper H or opening, through which the meat is
tered. Passing through the cylinder is a shaft A, upon the outer end of
hich is a crank D, Fig. 2, or wheel or pulley E, Fig. 1, by which it is
be rotated by power or hand. This shaft A is formed with a feeding
iral blade W inside the cylinder B, below the hopper H, and further along
the shaft are cutters a, a, arranged in a spiral position, but each cutter is
rmed of a blade of metal set at right angles to the shaft with a curved
tting edge (see Fig. 3), and within and attached to movable bars 6. Setting

page_text: in recesses in the cylinder B similarly shaped stationary cutters c, c, are
fitted. The set of cutters revolved by and with the shaft A act like shears
against the said stationary cutters c, c, to cut up and mince the meat, the
spiral blade W forcing the pieces of meat along to the cutters. At the delivery
end of the cylinder B is a stationary is a stationary plate of sheet metal d,
perforated with holes, that detains any pieces of meat that are too large to pass
through the holes, and on each side of the plate there are cutters e, e, see
Figs. 2 and 4, the same as aforesaid cutters a, a. The cutters e, e, cut off
the pieces of meat that otherwise might obstruct the holes in the plate d and
stirring fingers f,f, are also applied to the shaft A on each side of the plate d.
From the end of aforesaid meat mincer or cutter the meats falls away from
an opening at o immediately into the sausage stuffer, or may be received in any
vessel and afterwards placed in the stuffer. This stuffer is formed as a vertical
hopper h, in the lower part of which is a cylinder i, rotated by a crank kon
its shaft; said cylinder is formed with radial slots parallel to its axis, and
in which slots are plates 2, 7, with projections n, n, at their ends running in
eccentric grooves in the sides of the hopper h at the ends of the cylinder
The cylinder touches the hopper h on one side, but is some distance
therefrom on the other, and a nozzle m is provided at one side of the
hopper lower down than the cylinder, and upon this nozzle the intestine or
skin is drawn. The cylinder i and its plates act like a rotary pump, and
take the meat from the hopper hand force it out of the nozzle into the bag,
skin, or intestine extending from said nozzle m, the meat issuing from the
nozzle with a continuous and rapid movement; s, Fig. 1, is a lever to the
clutch c, for connecting or disconnecting the wheel E and shaft A. This
meat cutter or mincer may be made of any desired size and with a greater or
less number of cutters than shown, and if desired the interior of the cylinder B
may be corrugated spirally near the spiral blade W, as shown in Figs. 1 & 2,
to aid in forcing the pieces of meat along to the cutters. The shaft A and
cutters may be lifted out when the upper half of the cylinder B is turned back
so as to afford opportunity for cleaning the parts. The perforated detainer d
also lifts out with the shaft, and when replaced in the cylinder is prevented
from turning with the shaft by the projection seen in Fig. 4 entering the
recess in the bottom of the cylinder B. The bars b and cutters c may also be
lifted out of their recesses in the cylinder B for cleaning or sharpening.
What is claimed and to be secured by Letters Patent is,―
First, a series of cutters on a revolving shaft in combination with the
stationary cutters and with a spiral wing to feed the meat to the cutters,
substantially as and for the purposes specified.

page_text: Second, a series of stationary knives formed with curved cutting edges as
set forth in combination with a series of revolving cutters passing between
such knives, whereby the meat is separated with a drawing cut, as specified.
Third, a perforated detainer applied to a meat mincer substantially as
specified, to retain the meat until properly comminuted, as set forth.
Fourth, the combination of the stirring fingers f with the cutters e and
perforated detaining plate d, substantially as specified.
Fifth, the sausage stuffer, composed of the hopper h, revolving cylinder i,
blades 1, and nozzle m, substantially as specified.
In witness whereof I, the said Joseph Donnell, have hereunto set my
hand and seal, this 29th day of January, in the year of our Lord
One thousand eight hundred and sixty-six.
