COMPLETE SPECIFICATION.
Improvements in Cork-cutting Machines.
I, GEORGE WHEELHOUSE ROBINSON, of the firm of Robinson Brothers of Broad
Street, Halifax, in the County of York, Cork Manufacturers, do hereby declare the
nature of this Invention, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
The object of my invention is to make a finished cork for bottling purposes upon
one machine to quarter and square, take off the corners and round the cork at one
forward movement of the slide carrying the cutters, or any two of such operations may
be performed on the said machine.
DESCRIPTION OF DRAWINGS.
Fig. 1, is a plan of a cork cutting machine, with my improvements applied.
Fig. 2, is a front elevation of Fig. 1.
Fig. 2, shows detached view of automatic moveable emery rollers for sharpening.
Figs. 3, 4, 5, 6 and 7 show views of enlarged details of cutters.
Figs. 8 and 9 show views of enlarged details of guage.
Upon a suitable frame A are pedestals D carrying rosettes B, C, for holding the
cork whilst being operated upon. Connected to rosette B is a spiral bar E passing
between runners or rollers F mounted in brackets Gattached to slide H. The slide H
being mounted in bearings upon the guide shaft J which is carried by an adjustable
frame K adjustable by means of set screws K' which raise or lower one or other end
of the frame K, according to the shape of the cork required.
The spiral bar E is so formed as to have the part marked E¹ flat, for giving the
required motion for quartering purposes, the part marked E twists for squaring
purposes and the part marked E³ has several quick twists in it for taking off the
corners or for rounding purposes.
Upon the frame A is fixed a slide or carriage Lattached to the rosette C, and
operated by the lever M connected by cord, and pulley N to a treadle P mounted upon
a treadle shaft P', a spring R returning the carriage.
Mounted upon the slide H is a guage S for regulating the thickness or width of the
cork to be operated upon, T is the quartering knife fixed to the slide H and adjustable
by means of the set screws or studs T¹, U are the squaring knives adjustable by
means of the screwed studs and nuts U upon which they are carried, V is the
rounding knife, also attached to the slide, W are the emery rollers for sharpening the
rounding knife V, X is the guard, Y is the handle for operating the apparatus.
For sharpening the cornering or rounding knife, I may employ moveable emery
rollers as shown at Fig. 2*.
W and Ware the emery rollers mounted upon studs W' and W' having springs W,
1 is a runner connected to slide 2, 3 is an arm pivotted at 4 and connecting the stud W
to the slide 2, by means of the stud W, the stud W carrying the emery wheel W¹
being connected to the slide 2 by arm 6 a projection 5 (upon the slide carrying the
knives) operates upon the runner 1 depressing it. When the knives are upon the
point of leaving the runners, the said runners W and Ware made to open by
the projection 5 depressing the runner 1 (which is connected to the slide 2) forcing
down the emery roller Wi by means of the arm 6 and forcing upwards the other
emery roller W by means of the pivotted arm 3 (attached to the slide 2) acting on the
lever. The projection also opens the emery rollers when the knife returns, so that
they only sharpen it on its forward movement.
The action is as follows:-
:-
A length of cork is placed against the curve S and between the rosettes B and C

page_text: which are then closed by operating the treadle P which brings the slide L, to which is
attached the rosette C towards the rosette B, thus clamping the cork between them,
the slide carrying the knives is then operated, bringing forward first the quartering
knife T which cuts the necessary width; then the cork being held by the rosettes B
and C, is turned one quarter of a revolution by means of the runners or rollers F
operating upon the spiral bar E, and as the squaring knives U are brought forward
by means of the slide H travelling upon the guide shaft J they cut off any superfluous
cork upon the back or belly of same, thus making it a perfect square, after which as
the slide still travels forwards the spiral bar gives the rosettes rather more than a
complete revolution, the rounding knife coming into operation and cuts off the corners
of the square, so as to prepare it for a subsequent process, or if required, making a
perfectly finished bottling cork by one movement of the slide carrying the knives.
Instead of performing the whole of the operation consecutively, it may do any two
of 'them, such as:-
Quartering and sanenin
which are then closed by operating the treadle P which brings the slide L, to which is
attached the rosette C towards the rosette B, thus clamping the cork between them
the slide carrying the knives is then operated, bringing forward first the quartering
knife T which cuts the necessary width; then the cork being held by the rosettes B
and C, is turned one quarter of a revolution by means of the runners or rollers F
operating upon the spiral bar E, and as the squaring knives U are brought forward

the slide still travels forwards the spiral bar gives the rosettes rather more than a
complete revolution, the rounding knife coming into operation and cuts off the corners
of the square, so as to prepare it for a subsequent process, or if required, making a
perfectly finished bottling cork by one movement of the slide carrying the knives.
Instead of performing the whole of the operation consecutively, it may do any two
of them, such as:
Quartering and squaring.
Quartering and rounding.
Quartering and cornering.
Squaring and rounding.
Squaring and cornering.
Having fully described the nature and particulars of the said invention, I would
have it understood that I lay no claim to the general construction of the machine, but
what I claim is :-
1. Mounting upon the knife slide the quartering knife, squaring knives and rounding
knife, and forming the spiral, so that the whole operation or any two of such may be
performed by one for ward movement of the slide, in the manner and for the purposes
such as shown and described.
2. The use and employment of the spiral rod formed for giving two or more distinct
movements to the cork for the purposes such as shown and described.
3. The use of the guage in combination with the series of knives such as shown and
described.
4. The use and employment of the automatic moveable emery rollers W and W for
the purposes such as shown and described.
