Improvements in Printing Presses.
We, LAURIS LARSEN CARSON, residing at No. 11, Stanwix Street, and ALBERT
FRIEDSAM, residing at No. 3737, Boquet Street, in the City of Pittsburg, County
of Allegheny, State of Pennsylvania, and United States of America, Correspon-
dents, 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; -
It is the custom with many newspaper publishers to allow news companies and
other dealers a rebate for unsold copies. In making returns to the publishing
companies, the dealers tear off the head lines of the first page of the paper and
send them to the publishers. The latter are subjected to great frauds by news-
boys and others tearing off the headlines from papers which have been thrown
away in street cars and elsewhere. These fraudulent headlines of papers are
sent to the publishers as portions of unsold papers, thereby subjecting them to
great loss.
Many devices have been suggested for preventing these fraudulent practices,
such as fastening together two or more pages of the paper in such manner by
paste or mechanical devices, that the portions which are to be returned to the
publishers will be mutilated when the paper is opened by the reader. The means
heretofore suggested have been impracticable either for the reason that the pages
cannot be secured together as rapidly as the paper is printed and folded, or the
pages have been so secured together that portions of the reading matter are
inutilated.
The object of the present invention is to provide means, operative at the same
speed as the printing and folding mechanism, to partially isolate or sever a por-
tion of a page of paper and to cause such partially isolated or severed portion c
to adhere to an adjoining page, so that on the separation of the pages the par-
tially severed portion will be easily separated from its page along the line of
partial separation and remain adherent to the other page."

In the practice of my invention, the edge of one of the webs, preferably the
outside web a, is caused to pass on its way from the printing cylinders to the
folders between rolls 1 and 1ª. One of these rolls is provided with a series of
pins 2, and the other roll with holes 3, into which the pins may pass so as to
form a line or lines of perforations in the web. These pins and
holes may be arranged as shown, to form a line of perforations
diagonally across the upper right hand corner of a sheet when
severed from the web, as shown in Fig. 10, or may be arranged
so as to partially sever portions of any desired shape along any edge of the web.
After the formation of the perforations, paste is applied to the inner surface of
the partially severed sections, or to the outer side of the second or inner web by
rolls 4 and 5, in such position that when the two webs pass one onto the other
just prior to the operation of the folders, the partially severed sections will be
caused to tightly adhere to the adjacent web.
It will be readily understood by those skilled in the art that the perforating
and paste applying mechanisms can be arranged so as to sever or isolate any por-
tion of any of the sheets forming the paper and to so apply the paste that such
partially severed or isolated portion will firmly adhere to the adjacent sheet, so
that such partially severed portion will be entirely torn out when the paper is
opened out. As a general thing, it will be more convenient to arrange the per-
forating and pasting rollers so as to operate on the outer edges of the outside
webs, as shown in Figs. 1, 2, 6 and 7. A desirable construction in so using the
mechanism consists in securing the rolls 1 and 1" on the extended hubs 6 of
pinions 7 and 8, which intermesh and are mounted on pins 9 and 10 secured in
the frame 11. This frame is so fastened to the frame of the printing press that
the edge of the outside web will pass between the rolls 1 and 1" and the rolls are
driven by a train of gearing extending from any suitable part of the press,
and so proportioned that the rolls 1 and 1" will have a peripheral speed equal
to the speed of the webs through the press.
It is preferred to apply the paste to the inner side of the portion partially
isolated, but in some presses the arrangement of the guide rollers and the proxi-
mity of the first and second webs and other structural features of the press may
render such application of the paste impracticable. As for example in the form
of press shown in Figs. and 2, the outside web a after being operated on by
the rolls 1 and 1ª passes over the guide roller 12 and then joins the inner web b
and the two webs are carried along by tapes 13 to the guide rollers 14 whence
the webs pass to the folder. If the paste should be applied to the inner surface
of any portion of the web a it would be rubbed off on the guide roller 12, and
then smeared on other parts of the web. To avoid such an objectionable feature,
provision is made for applying the paste to portions of the outer surface of the
inner web b corresponding in position to the partially severed or isolated portions
of the web a, so that when the webs come together such partially severed portions
of web a will be pressed onto the pasted portion of web b. It is also charac-
teristic of the arrangement of the outer and inner webs in some presses that the
webs are too nearly adjacent to permit of the employment of a paste applying
roll equal in peripheral length to the length of the sheets into which the webs
are divided. In such case a smaller roll having a peripheral length equal to
half or quarter of the length of the sheets is so mounted on a movable part,
which is shifted to bring the paste applying portion of the roll against the web b

page_text: at every second, third or fourth revolution thereof dependent upon the relation
of the length of the periphery of the roll to the length of sheets into which the
web is to be divided.
In applying my improvement to such a press, the roll 4 is preferably secured
on the extended hub of the pinion 15, which is loosely mounted on a pin 16,
which is secured on one arm of a lever 17. This lever is pivotally mounted on
the pin 10 supporting the roll 1" and the opposite end of the lever projects into
the path of movement of a cam projection 7" on the hub of the pinion 7. As the
rolls 1 and 1 have a peripheral length equal to the lengths of the sheets they
are geared to make one revolution while any given point of the continuous web
is travelling a distance equal to the length of sheets into which
the web is subsequently cut. The pin 16 on which the pinion 15
and roll 4 are mounted is SO located on the arm of the lever 17,
that the pinion will be constantly in mesh with the pinion 7,
thereby ensuring the constant rotation of the roll 4. This roll is preferably pro-
vided with a projection 18 having a shape and superficial area proportional to
the area to which paste is to be applied. As shown in Fig. 1 the lever 17 is so
shaped that the roll 4 will project between the webs a and b and the roll is so
held normally by the spring 19 that the projection 18 will pass against the
outer surface of the web b at each revolution, but contact with the web is pre-
vented at every other revolution of the roll by the shifting of the lever 17 by the
cam 7". In order that the projection 18 may press firmly against the web b, the
latter is supported by a roll 5 loosely mounted on a pin 20 projecting from an
angular extension 21 of the frame 11. This roll is so arranged that the web b
will always pass along in contact therewith, and will rotate freely when the web
is being acted on by the projection 18.
Paste is applied to the surface of the projection by a roll 22 mounted in the
lower end of a paste receptacle 23 carried by the lever 17. The
roll is rotated intermittingly by a pin 24 on the side the roll 4
striking against and shifting a lever 25 mounted on the shaft of the roll 22. On
the lever is mounted a spring actuated pawl 26 adapted to engage the ratchet 27
on the shaft of roll 22. As the roll 22 is rotated it will bring portions newly
covered with paste in position to apply the paste to the surface of the projec-
tion 18.
In some presses the arrangement of the webs is such as to afford ample room
for the application of my improvements thereto, in such manner that portions of
the outside web cannot only be perforated or partially severed, but the paste
can be applied to the inner surface of such portions. Such a press is illustrated
in Figs. 6 and 7, the outside web being indicated at a and the inside web at b,
said webs being superposed one upon the other as they pass around the guide
roller 28. In adapting my improvements to such a machine, the rolls 4 and 5 are
so arranged that the web a will pass between immediately after being operated
on by the rolls 1 and 1°. The roll 4 is made of such a size that the diameter
of the circle described by the surface of the projection 18 is equal to the diameter
of the roll 1 or 1ª and the pin on which the roll and its driving pinion are
mounted is fixed to the frame 11. The paste receptacle 23 is connected to the
frame 11 in such manner that its roll 22 is held in operative relation to the roll 4.
As the copies of some editions are not returnable and need not therefore be
marked, it is preferred that provision should be made for shifting the marking
mechanism out of the line of movement of the webs. To this end the frame 11
is provided with sockets 29 for the reception of supporting pins 30 secured to
the frame of the press. A lever 31 is connected by a link 32 to the frame 11,
whereby the frame can be shifted along the pins 30 into and out of operative
position, as required.
This mechanism consists of two rolls 33 and 34, secured upon the hubs of
intermeshing pinions 35 and 36, which are loosely mounted on pins 37 and 38,
secured in a frame 39. As clearly shown in Figs. 11, 12, 13 and 15, this frame

page_text: is provided with eyes or sockets 40, adapted to slide upon guide pins 41, having
their outer ends firmly secured to the frame of the press. The frame 39 and the
parts carried thereby are adapted to be shifted along the pins 41 by means of a
lever 42, connected to the frame 39 by a link 43. The roll 34 is provided with
perforations through its perimeter for the entrance of a series of the perforating
needles 44, carried by the roll 33. The needle 44 and the perforations in the
opposing roll are arranged so as to form a line or series of perforations in the
web or sheet, that a portion thereof may be easily detached without any injury to
other portions of the sheet. These needles 44 are secured in a head 45, provided
with a stem 46, arranged to move back and forth in suitable guides formed on
the web of the roll 33, in such manner that the needles will move back and
forth through suitable openings in the rim of the roll 33, as clearly shown in
Figs. 13, 14, 15 and 16. In the construction shown in Figs. 13 and 14, the
stem 46 is surrounded by a spring 48, bearing at its ends against a shoulder on
the stem and one of the guide bearings 47. This spring serves to hold the inner
end of the stem 46 against the surface of a cam 49, secured upon the pin 37,
around which the roll 33 and its guiding pin 35 revolve. The cam 49 is so con-
structed that during part of the revolution of the roll 33, the needles 44 will be
forced out through the rim of the roll and during the remainder of the revolution
of the roll will be drawn within or flush with the outer surface of the rim for
a purpose to be hereinafter described. On the surface of the roll 33 and closely
adjacent to the perforating needles is secured a block 50, preferably having a sur-
face shape corresponding to the shape of the portion of the web or sheet to be
isolated but somewhat smaller in area. This projection or block is designed to
apply paste to the partially severed portion or portions of the web, so that when
the web is superposed upon the web e as they pass around the guide roller 51,
this partially severed portion would be caused to adhere to the web c. In order
to apply paste or other adhesive material to the surface of the block or projec-
tion 50, a paste receptacle 52 is secured to an arm or extension 53 of the
frame 39, preferably immediately above the center of the roll 33. The lower end
of this paste receptacle is closed by a roller 54, adapted to be rotated step by
step by a lever 55, operating through a pawl and ratchet mechanism, as
described in the application above referred to. The roll 34 simply serves as a
support for the web during the perforating and pasting operation.
The rolls 33 and 34 are driven through any suitable form of gearing from one
of the driven portions of the printing press, so that they will have a peripheral
speed equal to the speed of the webs through the press and in the same direction.
Referring to the construction shown in Figs. 13 and 14, it will be seen that, as
the needles 44 and block 50 move up towards the paste applying mechanism, the
needles 44 will be withdrawn within the rim of the roll 33, so as to prevent the
application of paste to their points. As the roll continues to rotate the needles
will be forced out by the cam 49, so as to be ready to operate and form a line
of closely adjacent perforations through the web b."
In the construction shown in Figs. 15 and 16, the needles 44 are moved posi-
tively in and out of operating position by means of a cam groove 56 formed in
the side of the disc 57 secured on the pin 37. The stem 46 of the head 45 is
provided at its lower end with a projection 58, having an anti-friction roller
mounted thereon so as to project into the cam groove in the disc.
While the construction illustrated in Figs. 11 to 16 inclusive is shown as
attached to that style or kind of press in which a double web a of paper passes
to and through a suitable slitting mechanism, and the portions b and c of the
divided web separate and pass around guides 61 and 62, and thence around
rollers 63 and 63 and 64 and 64ª, and then come together one upon the other,
and pass around a roller 51 to the folding mechanism, it is as readily applicable
to other forms or constructions of presses. As it is customary for the news-dealers
to return to the publishers portions of the outside sheet of unsold papers, my
improved mechanism is shown so attached to the frame of the press as to operate
upon the web, as b, which will form the outside sheet of the completed paper.
