page_text: LETTERS PATENT to James Frederick Lovelock, of 158, Lansdowne Road,
Hackney, in the County of Middlesex, for the Invention of "IMPROVE-
MENTS IN MACHINES FOR MINCING AND PREPARING FOOD AND OTHER SUB-
STANCES.
"
Sealed the 21st July 1876, and dated the 15th February 1876.
PROVISIONAL SPECIFICATION left by the said James Frederick Lovelock at
the Office of the Commissioners of Patents on the 15th February 1876.
JAMES FREDERICK LOVELOCK, of 158, Lansdowne Road, Hackney, in the County
of Middlesex. "IMPROVEMENTS IN MACHINES FOR MINCING AND PREPARING FOOD
AND OTHER SUBSTANCES."
The said improvements relate to that description of machines used for mincing
food and other substances, such as pelts and similar matters which a nozzle or
delivery tube is used, through which the substance minced passes from the said
machines, and the object of the said improvements is to provide a simpler and more
efficient method of connecting and disconnecting the said nozzle to and from the
body of the said machines.
In carrying out this Invention I make the aperture in the body of the said
machine through which communication is made with the passage in the nozzle with
a conical or recessed edge on its outer side, so as to form a seating to receive the
end of the nozzle, and I cast on or otherwise attach to the said body of the machine
two or more studs or projections. These studs or projections I place concentrically
and at about equal distances apart around the said conical or recessed seating, and
each of them is provided with a notch formed in its inner side.
The nozzle I form of tinplate or other suitable substance, and to one of its ends I
attach by soldering or other means a ring of any suitable metal, and I make the
said ring of such a diameter as to pass between the inner sides of the said studs or
projections, and the outer end of the said ring I shape so as to fit the said conical or
recessed seating. The said ring I also provide with an enlargement or flange, in
which notches or passages are made corresponding in size and position to the studs
or projections on the body of the machine, and the said enlargement or flange I
make to fit into the notches formed in the inner sides of the said studs or projections.
The nozzle thus formed is connected to the body of the machine by passing the said
studs or projections through the notches or passages in the said flange and pressing

page_text: the said nozzle into the seating, and then by turning the said nozzle round a
portion of a revolution, the enlargement or flange part of the said ring engages
itself in the notches formed in the inner faces of the said studs or projections and
securely holds the said nozzle, and at the same time connects it to the body of the
said machine. By turning the said nozzle in the reverse direction until such time
as the notches or passages of the said flange are in line with the said studs or
projections, the said nozzle can with equal facility be disconnected from the body of
the machine.
To ensure a firm attachment between the said nozzle and the body of the
machine the said flange is preferably made of a wedge shape, so as to permit of its
tightening up towards the conical or recessed seating in the body of the machine
when it is rotated in the notches of the said studs or projections, and the said
flange may also be provided with a stop so as to limit the distance through which
the said nozzle may be rotated.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said James Frederick Lovelock in the Great Seal Patent Office on the
25th July 1876.
JAMES FREDERICK LOVELOCK, of No. 158, Lansdowne Road, Hackney, in the
County of Middlesex. "IMPROVEMENTS IN. MACHINES FOR PREPARING FOOD AND
OTHER SUBSTANCES."
The said improvements relate to that description of machines used for mincing:
food and other substances, such as pelts in which a nozzle or delivery tube is used,
through which the substance minced passes from the said machines, and the object
of the said improvements is to provide a simpler and more efficient method of
connecting and disconnecting the said nozzle to and from the body of the said
machines.
In carrying out this Invention I make the aperture in the body of the said
machine through which communication is made with the passage in the nozzle with
a conical or recessed edge on its outer side so as to form a seating to receive the
end of the nozzle, and I cast on or otherwise attach to the said body of the machine
two or more studs or projections. These studs or projections I place concentrically
and at about equal distances apart around the said conical or recessed seating, and
each of them is provided with a notch formed on its inner side.
The nozzle I form of tinplate or other suitable substance, and to one of its ends I
attach by soldering or other means a ring of any suitable metal, and I make the
said ring of such a diameter as to pass between the inner sides of the said studs or
projections, and the outer end of the said ring I shape so as to fit the said conical or
recessed seating. The said ring I also provide with an enlargement or flange in
which notches or passages are made corresponding in size and position to the studs
or projections on the body of the machine, and the said enlargement or flange I
make to fit into the notches formed in the inner sides of the said studs or projections.
The nozzle thus formed is connected to the body of the machine by passing the said
studs or projections through the notches or passages in the said flange and pressing
the said nozzle into the seating, and then by turning the said nozzle round a
portion of a revolution the enlargement or flange part of the said ring will engages
itself in the notches formed in the inner faces of the said studs or projections and
securely holds the said nozzle, and at the same connects it to the body of the said
machine. By turning the said nozzle in the reverse direction until such time as the
notches or passages of the said flange are in line with the said studs or projections,
the said nozzle can with equal facility be disconnected from the body of the said
machine.
To ensure a firm attachment between the said nozzle and the body of the
machine, the said flange is preferably made of a wedge shape, so as to permit of its

page_text: tightening up towards the conical or recessed seating in the body of the machine
when it is rotated in the notches of the said studs or projections, and the said
flange may also be provided with a stop so as to limit the distance through which
the said nozzle may be rotated, and to more fully explain my Invention reference
is had to the accompanying Drawings.
Figs. 1 and 2 shew the machine with the nozzle or deliv tube connected.
Figs. 3 and 4 are an elevation and plan of the machine with the nozzle
removed.
Fig. 5 is the nozzle; and Fig. 6 is a section of the end of the machine at p, p,
Fig. 4.
a is the aperture in the body of the machine; b, b, the conical or recessed seating
formed on the outer edge of the aperture; r, r, the ring attached to the nozzle
tube g, g; and c, c, is the conical end shaped to fit the seating at b, b; f, f, is the
flange or enlargement; n, n, the notches in the said flange; 8, 8, are the studs or
projections; and x, x, are the notches in the said studs, the letters correspond to
each of the Figures.
Having thus described the nature and object of my Invention I claim the method
of attaching the nozzle or delivery tube to machines used for mincing food and other
substances by means of a conical or recessed seating, two or more notched studs or
projections attached to the body of the machine, and a suitable notched flanged
ring formed on or attached to the nozzle or delivery tube, substantially as herein-
before described.
In witness whereof, I, the said James Frederick Lovelock, have hereunto
set my hand and seal, this Eleventh day of July, One thousand eight
hundred and seventy-six.
