IMPROVEMENTS IN CORK CUTTING MACHINES to be as follows:
Year: 1885

page_text: We JAMES CORT and SAMUEL STEVENSON both of 21 Lower Bland Street,
Great Dover Street, in the County of Surrey, Engineers do hereby declare the
nature of our said invention for "IMPROVEMENTS IN CORK CUTTING MACHINES
to be as follows:-
"
This invention has for its object the construction of cork cutting machines in
such a manner that they may coinbine simplicity, lightness, economy and thorough
efficiency.
The machine consists of three principal parts, a stationary frame mounted upon
standards at each end, a vertical sliding piece or spindle frame, and a knife carriage
with its supporting bed. The spindle frame is attached to the stationary frame
and is capable of sliding up and down between two guides. In front of the spindle
frame there is an arrangement consisting of a bent lever, handle, cam, and two
adjusting screws whereby the diameter of the finished cork can be regulated, and
a second cut or shaving of cork removed if found necessary to perfect it. The top,
of the spindle frame carries two fixed and one movable poppets and a long spindle
or mandrel, between the end of which and the movable poppet the cork to be cut
is fixed. Between the fixed poppet and the movable one there is a spring that
keeps the latter away from the former, the movable one being brought into a
suitable position for gripping the cork by a cord which passes from it over a
pulley to a treadle beneath. The bed supporting the knife carriage, at or near
the centre of its length is pivotted to the stationary frame, and can be raised or
depressed so as to form any suitable angle to the horizontal, by a vertical screw
working through a nut fixed to the said frame, the bed being fixed when adjusted
by a horizontal screw, the nut of which is at the back of the bed. The knife is
fastened by adjusting screws to its carriage which works in guides upon the bed,
being driven backwards and forwards by a suitable handle. Attached to the back
of the knife carriage there is a short arm to which the ends of a gut band are
fixed, the band passing over a pulley at each end of the frame. One of the pulleys
is pivotted to the bed and the other is fastened to a spindle which carries a toothed
bevel wheel at its extremity, and gears into another toothed bevel wheel attached
to the rear end of the long spindle or mandrel before mentioned.
The action of the apparatus is as follows. The knife, carriage and bed being
adjusted and the cork frame being raised to a suitable height, a rectangular

page_text: piece of cork is placed between the mandrel and movable poppet. The treadle is
then pressed down with the foot when the cork will be securely gripped. On
thrusting forward the knife, motion is thereby imparted by means of the gut band
to the pulley, and by it conveyed through the geared wheels to the spindle, or
mandrel which revolves and carries the cork. As the knife advances the cork
rotates and being brought into contact with it, the cork is turned, or cut into the
proper cylindrical shape, a second cut if necessary being effected by manipulating
the handle attached to the bent lever and by another thrust of the knife forwards.
On drawing back the knife and taking the pressure off the treadle the cork will
be released, when it may be removed, another piece of cork placed in its stead and
the operation repeated.
When the rough rectangular pieces of cork are, in order to economize stuff, to
have only their extreme angles rounded off, a somewhat different spindle frame is
required. In this case the frame has two slides at each end, one for adjustment
to the size of the cork required, and the other to enable the cork to rise and fall so
as to bring it in contact with the knife edge at such intervals that only the angles
of the cork will be removed. The motion for raising and depressing the cork is
produced by fixing a suitably shaped cam upon the shaft that carries the band
pulley and toothed wheel. This cam acts upon a lever pivotted to the frame, and
as one end of the lever rises and falls with the action of the cam so does the other
end raise or depress the sliding spindle frame.
Instead of the gut band and pulley, a flat chain band and strap with suitable
wheel and pulley may be used, and in the arrangement for cutting off the angles
of the cork only, the movable poppet is kept towards the fixed poppet by the spring
instead of away from it, as in the first mentioned case.

page_text: Improvements in Cork Cutting Machines.
We JAMES CORT and SAMUEL STEVENSON both of 21 Lower Bland Street, Great
Dover Street, in the County of Surrey, Engineers, do hereby declare the nature
of our invention for "IMPROVEMENTS IN CORK CUTTING MACHINES " and in what
manner the same is to be performed, to be particularly described and ascertained in
and by the following statement, reference being bad to the accompanying drawings
and to the letters and figures marked thereon, that is to say -
This invention has for its object the construction of cork cutting machines in
such a manner that they may combine simplicity, lightness, economy and thorough
efficiency.
In order that the invention may be more easily understood drawings are attached
hereto, Fig. 1 being a front elevation, Fig. 2 a plan, Fig. 3 an elevation of the end
of Fig. 1 next to it, and Fig. 4 an elevation of that part of the end of Fig. 1 next
to it, but drawn to a larger scale the part shown in section being through A, B,
Fig. 1. Fig. 5 is a front elevation of part of the machine used for cutting off the
angles of corks, and Fig. 6 is an end elevation of that part of Fig. 5 next to it.
Fig. 7 is a plan of the knife carriage, Fig. 8 an elevation, and Fig. 9 a section of
the same through m, p, Fig. 7 the top plate not shown in Fig. 7 being in elevation.
In each of the Figs. similar letters refer to the same parts.
The machine consists of three principal parts, a stationary frame C mounted
upon standards D, D, at each end, a vertical sliding piece or spindle frame E, and
a knife carriage h with its supporting bed F. The spindle frame E is attached is
attached to the stationary frame C and is capable of sliding up or down between
two guides G, G.--In front of the sliding frame there is an arrangement consisting
of a bent lever H, a handle I, cam J, and two adjusting screws K and L whereby
the diameter of the finished cork can be regulated, and a second cut or shaving of
cork removed if found necessary to perfect it. The top of the spindle frame
carries two fixed poppets M, M and one movable poppet N and a long spindle or
mandrel O, between the end of which P and the movable poppet N the cork to be
cut is fixed. Between the fixed poppet M' and the movable one N there is a
spring that keeps the latter away from the former, the movable one being brought
into a suitable position for gripping the cork by a cord which passes from it over
a pulley to a treadle Q beneath.-The rocking bed I supporting the knife carriage h,
at or near the centre of its length is pivotted at R to the stationary frame, and can
be raised or depressed so as to forin any suitable angle to the horizontal thus
giving the requisite taper to the cork to be cut, by a vertical screw S working
through a nut fixed to the said frame, the bed being fixed when adjusted by a
horizontal screw T, the nut of which is at the back of the bed. The knife U is
adjusted by the screws V V and fastened by screws and nuts n, n, to its carriage
which works in guides upon the bed, being driven backwards and forwards by a
suitable handle W. Attached to the back of the knife carriage there is a short
arm X to which the ends of a gut band Y are fixed, the band passing over a
pulley Z at each end of the frame. One of the pulleys is pivotted to the bed and
the other is fastened to a spindle a which carries a toothed bevel wheel bat its

page_text: extremity and gears into another toothed bevel wheel c attached to the rear end of
the long spindle or mandrel before mentioned.
The action of the apparatus is as follows. The knife, carriage and bed being
adjusted and the cork frame being raised to a suitable height, a rectangular or
other shaped piece of cork is placed between the mandrel and movable poppet.
The treadle is then pressed down with the foot when the cork will be securely
gripped. On thrusting forward the knife motion is thereby imparted by means of
the gut band to the pulley, and by it conveyed through the geared wheels to the
spindle or mandrel which revolves and carries the cork. As the knife advances
the cork rotates and being brought into contact with it, the cork is turned, or cut
into the proper cylindrical shape, a second cut if necessary being effected by
manipulating the handle I attached to the bent lever and by another thrust of the
knife forwards. On drawing back the knife and taking the pressure off the treadle
the cork will be released, when it may be removed, another piece of cork placed in
its stead, and the operation repeated.
When the rough rectangular pieces of cork are, in order to economize stuff, to
have but little more than their extreme angles rounded off, a somewhat different
spindle frame is required. In this case the frame has two slides d and e Fig. 5 at
each end, one for adjusting to the size of the cork required, and the other to enable
the cork to rise and fall so as to bring it in contact with the knife edge at such
intervals that but little more than the angles of the cork will be removed. The
motion for raising and depressing the cork is produced by fixing a suitably shaped
cam fupon the shaft that carries the band pulley and toothed wheel. This.cam
acts upon a lever g pivotted to the frame, and as one end of the lever rises and
falls with the action of the cam so does the other end raise or depress the sliding
spindle frame.
Instead of the gut band and pulley, a flat chain band and strap with suitable
wheel and pulley may be used, and in the arrangement for cutting off little more
than the angles of the cork the movable poppet is kept towards the fixed poppet
by the spring instead of away from it, as in the first mentioned case.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that
what we claim is
1.-The vertical sliding piece E together with the lever H, handle I, cam J, and
adjusting screws K, and L, as herein described and shown on the drawings
Figs. 1. 2 and 3.
2. The rocking bed F Fig. 3 for supporting the knife carriage h,-the screws S
for adjusting the inclination of the bed and carriage and the screw T working in
the slott of the frame for holding the same, as herein described and shown on the
drawings.
3. The mode of attaching the knife by means of the screws V V and nuts n, n,
as herein described and shown on the drawings.
4. The vertical slides d and c Fig. 5 carrying the spindle carriage as herein
described and shown on the drawings,-and
5. The cam f and lever g Figs. 5 and 6 as herein described and shown on the
drawings.
