page_text: I, JOHN DAKIN, of High Lee Mill Lee St Oldham in the County of Lancaster,
Cork Manufacturer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to improvements in cork-boring machines and has for its
object to provide means whereby cork can be bored better and speedier than
heretofore has been the case.
To this end I employ on a bed or suitable foundation opposite to and a suitable
distance apart from each other, a bracket in which is mounted a hollow rotary
spindle and a bracket, having a feed rod which is fitted central to & in line with
the said hollow spindle.
The end of the latter opposite to the feed rod, is made to receive a suitable
circular cutter or boring tool, to which rotary motion is imparted by means of a
pulley keyed onto the said hollow spindle.
:
Between the said feed rod and boring tool I employ on the said bed or foundation
a bracket or cork holder which is arranged to be slid backwards and forwards from
and against the boring tool and feed spindle by means of a hand lever.
Into the said bracket are fitted V shaped steps which can be adjusted centrally
by means of set screws, the top step being connected to a hinged lid formed with
a projection or pin, which is caused by means of a spiral spring to ride on a cam
arranged in combination there with.
The said cam is so shaped as to open the cork-holder when it has to be charged
with corks, and to close and grip the corks tightly, the moment before the cork
comes into contact with the boring tool; which takes place by sliding the cork
holder by means of the said handle, against the boring tool.
The cork holder opens on its return & permits the feed rod to push another
cork into position, and pushes the one bored, out of the holder into a suitable
receptacle.
To the said cork holder is fixed a rod which by means of a link is connected to
another rod sliding in the said hollow spindle which latter rod, after a cork being
bored, pushes the cutting, out of the boring tools.

page_text: I, JOHN DAKIN of High Lee Mill, Lee St. Oldham in the County of Lancaster,
Cork Manufacturer, 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:-
My invention relates to improvements in cork boring machines and has for its
object to provide means whereby cork can be bored better and speedier than
heretofore has been the case.
And in order that my invention may be better understood I have caused to be
appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Fig. 1 is a front elevation and Fig. 2 a plan of the complete machine constructed
according to this my invention.
Fig. 3 is a longitudinal section.
Fig. 4 an end view, Figs. 5, 6 & 7, front and back views respectively of the
cork holder.
Fig. 8 shows a cork before, and
Fig. 9 a cork after the operation of boring.
In carrying out my invention I employ on a bed a or suitable foundation,
opposite to and a suitable distance apart from each other, a bracket b in which is
mounted a hollow rotary spindle c and a bracket d, having a feed rod e which is
fitted central to and in line with the said hollow spindle c.
The end of the latter opposite to the feed rod e is made to receive a suitable
circular cutter or boring tool f to which rotary notion is imparted by means of the
pulley g keyed onto the said hollow spindle.
Between the said feed rode and boring tool f I employ in a bed-plate h¹ fixed
adjustable by means of bolts to the said bed a or foundation, a bracket or cork
holder h which is arranged to be slid backwards and forwards from and against
the boring tool f and feed spindle e by means of a hand lever o, having its fulcrum
at o¹ on the bed plate h¹ and engaging a stud o², fixed into the bracket or holder h.
Into the said bracket are fitted V shaped steps i and i', which are kept a certain
distance apart by means of an adjustable screw pin c¹ & can be adjusted centrally
by means of set screws 61, the top step being connected to a hinged lid k formed
with a projection or pin k¹ which is caused by means of a spiral spring 1 to ride on
and be in constant contact with a cam m arranged in combination therewith and
fixed to the bed plate h¹ by means of the bracket f¹.
The said cam is so shaped as to open the cork holder when it has to be
charged with a cork, and to close and grip the cork tightly, the moment before the
cork comes into contact with the boring tool f, which takes place by sliding the
cork holder by means of the said handle o against the boring tool f.
The cork holder h opens on its return and permits the feed rod e to push another
cork, which has previously been put into the channel 6', fixed to the step i into
position between the steps i, & i', and pushes the one bored, out of the holder or
steps and through a trough c³ into a suitable receptacle.

page_text: To the said cork holder his fixed a rod q which by means of a link p is
connected to another rod s sliding in the said hollow spindle c which latter rod
after a cork being bored, pushes the cutting out of the boring tool f.
The rod q also carries a brush t or lubricator medium which bears against the
boring tool fand keeps the same constantly lubricated.
A modification in the employment of this cam m consists in fixing the same
above the pin k¹ see Fig. 6, in which case the cam m only, causes the closing of the
cork holder h or steps i and while a spring m³ is employed between the latter
to keep the pin k¹ in constant contact with the cam m and to open the holder h or
steps i and ¹.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what
I claim is:
1st In a cork boring machine :-The general construction and arrangement of
parts substantially as described and shown in the drawing.
2nd The bracket or cork-holder h capable of being slid to and from the boring
tool by means of a hand lever o, carrying adjustable steps i and i¹, between which
the cork to be bored is placed, substantially as described and illustrated in annexed
drawing.
3rd The hinged lid k carrying the top step i¹, and being formed with a projection
or pin k¹, which latter is caused to ride on and be in constant contact with the
cam m, fixed to the bed plate h, by means of a bracket f¹, substantially as described
and illustrated in annexed drawing.
