"A NEW OR IMPROVED PRESS FOR THE EXTRACTION OF JUICE
FROM MEAT, AND FOR OTHER PURPOSES." A communication by Charles Drevelle,
of 8, Boulevard St. Marcel, Paris.
This press consists of a stand or frame, of a rectangular or circular vessel to
receive the meat, of a draining-plate made of cast iron or any other metal or
suitable material, provided with grooves radiating from the centre to the circum-
ference, & concentric, by which the juice flows to an opening in the centre of the
plate forming the bottom of the receiver, of an inclined plane upon which the juice
falls from the said opening, of a perforated plate or wire gauze placed upon this
plate to prevent the stopping up of the grooves, & of a filtering tissue of wool,
hemp, or some other suitable textile material lying on the perforated plate or the
wire-gauze, & on which the meat to be compressed is placed.
This pressure is given to the meat by means of a piston, rectangular or circular,
according to the form of the receiver, working in this receiver; the top of the
piston is provided with a projection in the form of a boss, worked by a lever, one
end of which is joined to an upright forming part of the stand or frame, whilst the
free end of the said lever, provided with a hole in order that it may work up &
down along a screw-rod attached to the frame, is worked by a fly-wheel, the nave
of which is elongated in the form of a semi sphere, which enters a corresponding
cavity in this free end of the said lever, thus forming a rotula joint by which the
screw-rod is prevented from being bent.

"A NEW OR IMPROVED PRESS FOR THE EXTRACTION OF JUICE FROM MEAT, AND
FOR OTHER PURPOSES." A communication by Charles Drovelle, of 8, Boulevard
St. Marcel, Paris.
The Invention relates to a special press for easily, promptly, and completely
extracting the juice from meat.
This press consists of a stand or frame, of a rectangular or circular vessel to
receive the meat, of a draining plate made of cast iron or any other metal or
suitable material, provided with grooves radiating from the center to the circum-
ference, and concentric, by which the juico flows to an opening in the centre of the
plate forming the bottom of the receiver, of an inclined plane upon which the juice 1
falls from the said opening, of a perforated plate or wire gauzo placed upon this
plute to prevent the stopping up of the grooves, and of a filtering tissue of wool,
hemp, or some other suitable textile material lying on the perforated plate or the
wire gauze, and on which the meat to be compressed is placed.
This pressure is given to the meat by means of a piston, rectangular or circular,
according to the form of the receiver, working in this receiver; the top of the
piston is provided with a projection in the form of a boss worked by a lever, one
_ end of which is joined to an upright forming part of the stand or frame, whilst the
free end of the said lever, provided with a hole-in-order that it may work up and
down along a screw-rod attached to the frame, is worked by a fly-wheel, the nave
of which is elongated in the form of a semi-sphere, which enters a corresponding
cavity in this free end of the said lever, thus forming a rotula joint by which the
screw rod is prevented from being bent.
"
Having thus briefly described the said Invention, I will now describe the same
more particularly by referring to the accompanying Drawings, of which Fig. 1 is a
longitudinal elevation of the apparatus, and Fig. 2 a central and vertical section of
the press through A, B, Fig. 1. The same letters represent corresponding parts in
these Figures.
A is the frame of the press; b, the receiver; c, the tissue filtering the juice from
the meat, and by which the micat is provented from getting to the lower parts, so as
to keep them cleau; d is the perforated plate or wire-gauze, the centre of which is
protected by a small washer of thin metal, soldered or riveted. This perforated
plate or the wire-gauze and the filtering tissue prevent the stopping up of the
openings through which the juice flows; f is the draining plate; g, the inclined
plane in the direction of its longitudinal axis, provided with a spout for the juice
to flow from the meat into the vessel intended to collect it.
B is the piston; h, the boss on the top of it; k, a flange or rim around the
lower face of the piston, by which the meat under pressure is prevented from
passing through the space between tho edge of the said piston and the side of the
receiver b.
D is the lever of pressure hinged at f' to an upright C forming part of the framo,
and which, by means of a crank-pim m, can be taken away when it is necessary to
remove the lever D in order to take the receiver b out and clean it. This receiver
is kept firmly in position by two shoulders d, d³, upon the frame, and two ears c¹
of the frame, which fit into cavities a of the recipient.
E is the flywheel acting on the lover D at 6" by its hub el, semispherical in shape,
which fits into the corresponding cavity of the said lever; F is the screw or

page_text: threaded rod along which the end of the lever rises and falls. This screw is fixed
to the frame by the pin F' so that it can follow the movement of the lever. The
course of the said lover is regulated by a milled nut G which can be placed at any
point of the screw F, according to the quantity of meat to be pressed. This nut is
kept fixed by a countor nut G₁
The fly wheel above stated can be replaced by any suitable handle. In the same
way the two nuts G, G³, can be replaced by a spiral spring which should surround
the screw F, and would lift up the lever D.
By using the apparatus above described all the juice contained in the meat can
be extracted; the apparatus is portable and need not be fixed upon a picco of
furniture like similar apparatuses now in use; nor has it tho disadvantage of these
others, the meat in thein being crushed by a cylinder, and the pressure obtained by
a screw, so that this pressuro is but slightly effectual, taking place continually,
and the meat following the rotatory motion imparted to the scrow, being triturated
so as to find its way into the holes intended for the juice to flow through, which it
obstructs so that the pressure is exerted upon an elastic body, which resists this
pressure and reabsorbs the juice by suction, which would flow away if it had a
free oxit.
Having thus described the nature of the said Invention, I claim and wish to
secure by Letters Patent the improvements in presses for the extraction of juice
from meat, and for other purposes, above described, and represented in the
accompanying Drawings.
In witness whereof, I, the said Henri Adrien Bonneville, have hereunto set
my hand and seal, this Twenty third day of December, in the year of our
Lord One thousand eight hundred and eighty.
