Improvements in Cutting Discs of Wood, Leather, Pasteboard, and
other like Materials, and in Machinery therefor.
I JAMES FIELDING SMYTH of 61 Great Patrick Street Belfast in the County of
Antrim in Ireland, Brassfounder, do hereby declare the nature of this invention to be
as follows:-
My invention relates to the production of Wood tops used to cover Corks of Soda
Water bottles and for the ends of Pill boxes and the like and of similar discs required
for other purposes.
I accomplish this object by bringing the material from which the discs are to
be cut into contact with the end of a metal Tube or semi-cylindrical blade
mounted on a Chuck revolving at a high speed and furnished with a sharpened
edge or with a sharpened tooth or sharpened teeth at the end referred to.

page_text: other like Materials, and in Machinery therefor.
I JAMES FIELDING SMYTH of 61 Great Patrick Street, Belfast in the County of
Antrim in Ireland, Brassfounder 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 the production of the wooden tops used to cover the corks of
Soda Water bottles and for the ends of pillboxes and the like and of similar discs
required for other purposes.
I accomplish this object by bringing the material from which the discs are to
be cut into contact with the end of a metal tube or semicircular blade mounted
on a chuck revolving at a high speed and furnished with a sharpened edge or with a
sharpened tooth or sharpened teeth, at the end referred to.
The chuck is fitted to a spindle set in a frame and furnished with a bevelled pinion
gearing with a toothed wheel driven by a prime mover in the ordinary way. I provide
a pedestal or socket set upon the frame opposite to the tube or blade having a
reciprocating motion over and around the tube or blade imparted to it by means of a
rectangular lever or rocking shaft and levers actuated by an eccentric or tippet
motion from one of the prime movers. I furnish the pedestal or socket with a mouth
piece to hold the material from which the discs are to be cut. And I regulate
the position of the material in the mouth piece by a pin at the side or end of
such mouthpiece which gauges the distance it should be advanced for each cut.
The machine may be fed by hand or automatically by ordinary mechanical
appliances.
I do not confine myself to the arrangement or construction of parts herein before
described inasmuch as such parts may obviously be disposed and constructed
in several other ways than those which I have already mentioned and shewn.
And in order that my said invention may be more fully understood I shall
now proceed to refer to the sheet of drawings hereunto annexed the same
letters of reference indicating the same or corresponding parts throughout all the
figures.
Fig. I represents a chuck furnished with a sharpened tube or blade and fitted
to a revolving spindle set in a frame and pedestal or socket with a mouth
diece for holding the slips, the chuck, blade and pedestal or socket being
puplicated.
Fig. II is an enlarged drawing of a blade furnished with a sharpened waved edge.
a, a are the frame; 6 is a revolving spindle; c, care chucks; d, d are tubes or blades;
e, e are pedestals or sockets having mouthpieces, f, for holding slips of material

page_text: to be cut into discs and driven against the tubes or blades, d, d, by the action of an
eccentric, g, upon levers h, h, which are restored to position by springs, i, i; k is a pin
for gauging the advance of the material in the mouth piece."
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim is
1. The cutting of wooden and other discs by means of a revolving tube or blade
constructed and employed substantially in the manner and for the purposes herein-
before mentioned and shewn in the drawings hereunto annexed.
2. The use in disc cutting machines of a pedestal or socket having a mouth piece
and stop constructed and employed substantially in the manner and for the purposes
hereinbefore mentioned and shewn in the drawings hereunto annexed.
3. The combination and arrangement of parts constituting my improved disc
cutter constructed and employed substantially in the manner and for the purposes
hereinbefore described and set forth and illustrated in the drawings hereunto
annexed.
