Improvements applicable to certain "Letterpress" Printing Machines
for Perforating or Cutting the Paper while or immediately after
such Paper is being or has been Printed.
We. WILLIAM JOHN TEER of 120 Clews Street, Gorton in the County of Lancaster,
Printer and THOMAS FORKNALL of Saint Ann's Wells, Ashton Old Road, Fairfield,
in the County of Lancaster, Engineer 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:-
Our invention relates to those printing machines in which a "taking off" cylinder
or roller is employed and consists in means by which the paper printed may be
perforated or cut while or immediately after such paper is being or has been
printed.
The first part of our invention consists in arrangements for forming lines of
perforations or cuts extending lengthwise of the paper.
According to this part of our invention upon the bar or rod extending lengthwise
of the cylinder or roller and secured to the framework of the machine and employed
to carry the guides usually employed we mount a disc or dises the edge or edges of
which forms or form a cutter, or cutters acting in conjunction with the "taking off"
roller or cylinder or a roller used in conjunction with the “taking off" roller or
cylinder and perforates or cuts or perforate or cut the paper passing between the said
disc or discs and the surface of the "taking off" roller or cylinder or the roller used
in conjunction therewith.
The taking off" roller or cylinder or the roller used in conjunction therewith
may be formed of any suitable wood or metal or any other suitable material or may
be provided with a portion or portions formed of any suitable metal or other suitable
material so that the disc or dises may perforate or cut the paper without unnecessarily
injuring the "taking off" roller or cylinder or the roller used in conjunction
therewith.
In the accompanying drawing Fig. 1 is a side view and Fig. 2 a front view of
so much of a letterpress printing machine of the kind to which our invention relates
as is requisite to illustrate the first portion of our invention. The same letters of
reference are applied to corresponding parts in both of the figures.
a is the bar or rod extending lengthwise of the cylinder or roller b and secured to
the framework of the machine and employed to carry the guides usually employed.
Upon the rod or bar a we mount a disc or discs such as e which disc or each of which
discs c is or are secured upon the bar or rod a by means of a set screw or set screws d.
The edge or edges of the disc or each of the discs c acting in conjunction with the
taking off roller or cylinder b perforates or cats or perforate or cut the paper passing
between the disc or each of the discs c and the taking off roiler or cylinder . The
circumference of the disc or cutter or of each of the discs or cutters c we form as a
cutting edge or cutting edges when it is intended that the paper passing between
the disc or cutter or discs or cutters e and the taking off roller or cylinder b is to be
cut or severed. In cases in which the paper passing between the disc or cutter or
discs or cutters c and the taking off roller or cylinder is to be perforated we form
the edge of the disc or cutter or each of the discs or cutters c witli teeth c' as shown
in Figs. 3 and 4.
The taking off roller or cylinder 6 may be formed of wood, metal or any other
suitable material or may be provided with portions or bands of metal or other suitable
material such as e so that the edge or edges of the disc or cutter or discs or cutters c
may cut or perforate the paper without unnecessarily injuring the “taking off” roller
or cylinder b.
One disc or cutter or two or more discs or cutters e may be employed according as
one line or two or more lines of cuts or perforations is or are to be formed in the

page_text: paper passing between the disc or cutter or discs or cutters c and the taking off
roller b.
Although we have above for convenience referred to the roller b as being the taking
off roller or cylinder we would have it understood that the disc or cutter or discs or
cutters c may be used in conjunction with a roller used in conjunction with the taking
off roller or cylinder of the printing machine.
A further part of our invention consists in arrangements for forming lines of per-
forations or cuts extending crosswise of the paper.
6.
According to this part of our invention we employ a cutter or cutters mounted
upon the bar or rod above mentioned which cutter or cutters is or are provided with
projecting ribs or blades extending crosswise of the paper passing between the said
cutter or cutters and the taking off" cylinder or roller or a roller used in conjunc-
tion with the said "taking off" cylinder or roller. The outer edges of such ribs or
blades by pressing upon the paper passing between the ribs or blades and the surface
of the "taking off" cylinder or roller perforate or cut such paper.
The "taking off" roller or cylinder or the roller used in conjunction therewith may
be formed of any suitable wood or metal or any other suitable material or may be pro-
vided with a portion or portions formed of any suitable metal or other suitable
material so that the ribs or blades may perforate or cut the paper without unnecessarily
injuring the "taking off" roller or cylinder or the roller used in conjunction
therewith.
Fig. 5 and Fig. 6 illustrate the second part of our invention, the same letters of
reference being applied to corresponding parts in both of the figures. Fig. 5 is a
front elevation and Fig. 6 a cross section of such portion of a printing machine of the
kind to which our invention relates as is necessary to illustrate this part of our
invention.
a is the bar or rod and c, c, dises or cutters similar to that or those previously
referred to in reference to Figs. 1 and 2. We mount upon the bar or rod a, a
cutter provided with ribs or blades fextending crosswise of the paper passing
between the cutter fand the taking off roller or cylinder b. The outer edges of the
ribs or blades of the cutter by pressing upon the paper passing between the ribs
or blades and the surface of the taking off roller or cylinder b perforate or cut the
paper according as the edges of the blades or ribs are formed for perforating or cutting
the said paper. When the blades or ribs flare to be used for perforating paper the
operating edges of such blades or ribs are formed with notches 2 such as are
shown in Fig. 5 as being formed in one of the blades or ribs but when the blades
or ribs are to be used for cutting or severing the paper the operating edges of such
blades or ribs f' are formed continuous as is the case with the blade or rib f³ in
Fig. 5.
The taking off roller or cylinder used in conjunction with the ribs or blades f¹
may be formed of any suitable wood or metal or other suitable material or may be
provided with portions a formed of any suitable metal or other material so that the
ribs or blades may perforate or cut the paper without unnecessarily injuring the
taking off cylinder or roller b.
The cutter and the ribs or blades' formed thereon will require to be made of the
length suitable for the work which they are required to perform. It will be obvious
that cutters having ribs or blades f₁ of various lengths may be provided for use in
each printing machine.
Although we have above referred to the bar or rod a as being the bar or rod which
carries the guides employed in conjunction with the taking off cylinder or roller such
bar or rod a may be a bar or rod specially provided to carry the discs or cutter or
dises or cutters c and cutter f above described or either of them.
Although we have hitherto referred to the roller b as being the taking off roller or
cylinder such roller may be any other convenient and suitable roller used in con-
junction with the taking off roller or cylinder of the printing machine.
Although we have above described and in Figs. 5 and 6 of the accompanying
drawing shown the arrangements forming the second part of our invention as being

page_text: employed in combination or conjunction with the arrangements forming the first part
of our invention we would have it distinctly understood that the arrangements forming
either part of our invention may be employed either apart from or in conjunction or
combination with the arrangements forming the other part of our invention.
By the means in which our invention consists the paper printed by the machine to
which our invention is applied may be perforated or cut while or immediately after
being printed the arrangements described in reference to the first part of our invention
enabling lines of perforations or cnts to be made parallel to the length of the paper
being printed and the arrangements described in reference to the second part of
our invention enabling lines of perforations or cuts to be made crosswise of the paper
being printed.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed we declare that what we
claim is :-
1. For use in a printing machine in which what is known as a taking off
cylinder or roller is employed the hereinbefore described arrangements for forming
lines of perforations or cuts extending lengthwise of the paper printed in such
machine which arrangements consist in a disc or cutter or discs or cutters
operating in conjunction with the taking off cylinder or roller or in conjunction
with a roller used in conjunction with the said taking off cylinder or roller
substantially in the manner herein before described in reference to and indicated in
and by Figs. 1 and 2 of the accompanying drawing.
2. For use in a printing machine in which what is known as a taking off
cylinder or roller is employed the hereinbefore described arrangements for forming
lines of perforations or cuts extending crosswise of the paper printed in such
machine which arrangements consist in a cutter or cutters provided with ribs or
blades such as f¹ operating in conjunction with the taking off cylinder or roller
or in conjunction with a roller used in conjunction with the said taking off cylinder
or roller substantially in the manner hereinbefore described in reference to and
indicated in and by Figs. 5 and 6 of the accompanying drawing.
