PROVISIONAL SPECIFICATION.
An Improvement in Cylinder Printing Machines.
We, LEONARD GUNN, of Victoria Mills, Bath, in the County of Somerset, Miller,
and EDWARD RICE, of Norfolk House, Acton Green, Chiswick, in the County of
Middlesex, Traveller, do hereby declare the nature of this invention to be as
follows:-
In order to occupy economically the width of a cylinder printing machine, a multiple
forme is often employed so as to print at once a number of copies side by side which
have afterwards to be separated by longitudinal cuts.
Also, in many cases, subjects are printed on cards to be folded in two three or
more folds, and at the folds the cards require to be partially cut through or
indented.
Our invention relates to appliances to cylinder printing machines whereby such
longitudinal cutting or scoring is effected as each impression leaves the press. For
this purpose we fix on the delivery side of the cylinder a frame in which two or more
circular knives are mounted free to revolve, these knives presenting their edges towards
the cylinder and being adjustable in position laterally to suit different widths
between cuts or scores, and being also adjustable towards or from the cylinder as
required for depth of cut. In cases where the sheet is to be cut into several widths,
we provide in each circular knife a notch or several notches which leave at intervals
in each cut parts uncut so as to hold the several parts of the sheet together until
they are delivered from the machine, whereupon they can be separated by hand,
cutting or tearing apart the short pieces which were left uncut.
Dated this 25th day of April 1889.

manner the same is to be performed, to be particularly described and ascertained in and
by the following statement :-

Fig. 1 of the accompanying drawings is a front view and Fig. 2 is an end view
of a printing cylinder with means according to our invention of cutting or partially
cutting scoring or indenting longitudinally the printed sheets.
A B is the cylinder, F parts of its shaft, C is a bar forming a dovetail guide fixed
parallel to the axis of the cylinder. In this guide are fitted to slide dogs D which
can be fixed by setting nuts at any part of the length of the guide. In each of the
dogs. D is fitted a transverse slide carrying a cutting or indenting wheel E which
can be adjusted by a screw more or less near to the surface of the cylinder. The
sheet G as it passes under the cutting or indenting wheels E is cut, scored or
indented longitudinally, at those parts of its surface to which the wheels E are
adjusted.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
In combination with the cylinder of a printing machine cutting or indenting
wheels adjustable in position, substantially as and for the purpose set forth.
