States of America.]
Improvements in Apparatus for Feeding Papers, Pamphlets, and
other similar Articles, to Wrapping and other Mechanisms, and
in Apparatus for Wrapping such Articles.
I, HENRY EDWARD NEWTON, of the Office for Patents, 6, Bream's Buildings,
Chancery Lane, in the County of London, Patent Agent, 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:
-
This invention relates generally to certain improvements in wrapping
mechanisms, and has for one of its objects to provide an improved wrapping
mechanism of that class used for folding and wrapping newspapers and other
periodicals for mailing or other purposes.
Another object of the invention is to provide an improved feeding mechanism
by which papers, pamphlets, and other similar articles may be fed from a bank
or pile to wrapping machines or other machines wherein it is desirable to take
articles singly from a bank or pile, and feed them to a machine.
Referring to that branch of the invention which relates more particularly to
the wrapping mechanism, it may be stated that the mechanism is of that class
in which the paper is advanced with one end of the wrapper projecting behind
the paper sufficiently to overlap upon a layer of wrapper on the paper, and the
paper then delivered between pressing surfaces, by which the loose end of the
wrapper is pressed down on the layer of wrapper on the paper and secured by
paste previously applied, and the invention, so far as it relates to the wrapping
mechanism, includes a novel construction of this class by which the carrier
moves the end of the paper past an abutment, by which the flap of the wrapper
is turned about the end of the paper, and delivers the end of the paper, with
the wrapper overlapped thereon, to the pressing devices, the especial object being
to provide a carrier which shall readily receive the paper, compress the paper
while the flap of the wrapper is being folded about its end, and then advance it
positively into the grasp of the pressing devices.
Wrapping mechanism constructed in accordance with this part of the invention
may be fed by hand, or any suitable devices may be provided for automatically
feeding the papers and wrappers at proper intervals, and it may be designed to
wrap papers which have been folded to the desired size for wrapping, or the
papers may be folded by any suitable mechanism embodied in, and forming a
part of, the machine, or the wrapping mechanism may be combined with the
folding and delivery mechanism of a printing press, as is customary with other
forms of wrapping mechanism now in use.
This branch of the invention, however, includes an improved folding mechanism
by which a complete folding and wrapping machine is produced, and this folding

page_text: mechanism includes a carrier which receives the paper from feeding devices,
and folds the paper on the desired fold line, by moving past a suitable abutment,
and delivers the folded edge of the paper between pressing devices, this part of
the invention relating especially to the manner of mounting and operating the
carrier, so that the receiving end of the carrier is first caused to move past the
abutment, and then advanced longitudinally to carry the folded edge of the paper
into the grasp of the pressing devices.
l'aste for securing the flap of the wrapper may be applied to the layer of
wrapper on the paper, or to the flap of the wrapper, by any suitable pasting
devices. It is preferable, however, to have the paste applied to the flap of the
wrapper just before it is turned about the end of the paper, and there is
employed for this purpose an improved pasting mechanism fully described herein-
after, which forms a feature of the present invention, and which may be used
in machines of other classes.
While, as has been stated, the wrapping machine which forms one branch
of this invention may be fed by hand, it is preferably automatically fed by
means of a mechanism which forms another branch of the invention. It will
be understood that in feeding papers, pamphlets, magazines, sheets, and other
similar articles, to wrapping machines, it is desirable, to ensure the perfect action
of the wrapping devices, that the articles to be wrapped be automatically fed
thereto, and fed with rapidity and decision. The feeding devices must operate
rapidly, in order that the wrapping machinery may not be limited in its out-
put. They must also act to feed the articles singly and in proper time, as a
failure to feed, or to feed properly, or to feed more than one article, interferes
with the action, and disarranges the operation of the wrapping machinery.
It is also very desirable that the wrapping machines be fed from a pile or
stack, which can be readily renewed or replenished from time to time, without
stopping either the feeding or the wrapping machinery, or in any way
interfering with its operation.
It is apparent that when the articles to be thus fed are taken from the bottom
of a pile or stack, the supply can be more readily renewed, and with much less
interference with the operation of the mechanism, than when the feeding is from
the top of the pile or stack, as feeding from the top of a pile or stack usually
requires somewhat complicated pile-raising mechanisms. When; however, the
feeding is from the bottom, much greater difficulty is experienced in detaching
single articles or papers, since, from the weight of the pile and other causes, the
liability of two or more articles to adhere is greatly increased.
It is the object of this branch of the invention, therefore, to produce a feeding
mechanism which shall be simple, and, therefore, economical to construct anil
maintain, which may, if desired, be used to feed from the bottom of the pile or
stack of papers or articles to be fed, so that the same may be replenished when-
ever desired, without stopping the action of either the feeding machinery or
the wrapping machinery, and which shall be certain in its operation, so that
only a single paper or article shall be taken from the pile at a time, and properly
fed to the machine.
As a full understanding of the several features of the invention can best be
given by a detailed description of the constructions, which embody the various
features of the invention in a preferred form, such a description will now be
given in connection with the accompanying drawings, which form a part of this
specification, and in which like characters of reference indicate the same
parts.

Figures 17 and 18 are detail views of the construction of this modification;
and,
Figures 19 and 20 are diagrammatic views of the modified feeding mechanism,
showing the parts in two positions.
Referring to Figures 1 to 6 of the drawings, the various parts of the wrapping
machine are supported by side frames A, and are so arranged that the papers,
being fed in at the rear end of the machine, either by hand or by the feeding,
mechanisms to be hereafter described, are associated with wrappers, and advanced
downwardly through the folding mechanism to the wrapping mechanism located
in the lower forward end of the machine.
The wrapping machine will be described by following the course of the
paper through the machine, describing the various parts generally in the order
in which they act on the paper.
The papers are fed into the machine by feeding tapes 10 and 11, turning
on rolls 12 and 13. The papers are advanced beyond the rolls 12 and 13 by
feeding tapes 14 passing around rolls 12 and around other rolls 15, and by a
sectional roll 16, plates 17 being preferably provided to support the papers
between the rolls 13 and 16.
As the paper advances beyond the rolls 15 and 16, its forward end is received
between the side plates a and b of a carrier 20. This carrier is pivotally mounted
in a rocking support formed by arms 21 carried by a rock shaft 22. The rear
end of the carrier, beyond the point of connection with the arms 21, is guided
and supported by a slotted bar 23, pivoted at the ends, so as to form rocking
guides for the carrier, and so positioned with relation to the rock shaft 22,
that when the arms 21 are rocked from the position shown in Figure 4 in the
direction of the arrow, the front or receiving end of the carrier will be first
moved transversely to the direction in which the papers are fed into the carrier,
as shown in dotted lines extending from the end of the side plates a, b, of
the carrier in Figure 4, the guides rocking as the carrier moves, and this
transverse movement of the end of the carrier will, as the arms 21 approach the
position shewn in dotted lines in said figure, be changed to a bodily movement
of the carrier forward in the direction of its length, so as to move it into the
position shown in dotted lines in said figure. The power for rocking the
support for the carrier, whereby the carrier is caused to move as above described,
may be applied in any suitable manner, and on any suitable part of the con-
struction. In the construction shown, the power is applied through the shaft 22.
For the purpose of folding the paper against the edge of the plate a of the
carrier, as the front end of the carrier is moved transversely, a suitable abutment -
is provided. In the construction shown, the sectional roll 16 acts as such an
abutment. By the movement above described, the carrier will be moved past
the abutment, so as to feed the paper against the abutment, and the carrier then
advanced longitudinally, to carry the folded edge of the paper between the

page_text: pressing and feeding devices, which are formed preferably by a roll 30 and
by tapes 31 passing around the roll 16 on the side toward the carrier, and
around the opposite side of the roll 30.
The shaft 22 is rocked for the advance movement of the carrier 20 by means
of a cam 24 on the main driving shaft 100, said cam engaging an antifriction
roll 25 on an arm 26 carried by the shaft 22. The cam 24 is formed to rock
the shaft 22 for the advance movement of the carrier, once for each revolution
of the main driving shaft, and to hold the carrier in its delivery position while
the paper is being drawn out of the carrier. A spring rod 27, connected to
an arm 28 on the shaft 22, holds the shaft 22 under spring tension, to cause the
roll 25 to follow the edge of the cam, and rocks the shaft to return the carrier to
its receiving position.
In the machine shown, the wrappers y are associated with the papers before
the papers receive their first fold, as above described. The wrapper web is fed
into the machine between feeding rolls 34 and 35, and advanced between per-
forating rolls 36 and 37, which are timed to perforate the wrapper web in the
desired wrapper lengths. The perforated web then passes between a second pair
of feeding rolls 38 and 39, from which it is advanced between tapes 40 and 41,
which tapes pass around the rolls 38 and 39, and around other rolls 42 and 43,
respectively, guides 44 and 45 also being preferably used between rolls 38
and 39 and rolls 42 and 43.
From the tapes 40 and 41, the wrappers are advanced over the roll 16, and
associated with the papers as they pass between the tapes 14 and the roll 16,
the parts preferably being timed so that the forward end of the wrapper_shall
meet the forward end of the paper, as shown, and the perforated wrapper being
broken by the tapes 31, which run at a higher speed than tapes 40, 41. The
wrapper is then fed forward with the paper into the carrier, and, being on the
lower side of the paper, when the paper has received its first fold, as above
described, the wrapper will be folded about the paper.
The tapes 31, after passing about half way around the roll 30, leave said
roll, and then turn in the opposite direction about the front of a sectional
roll 32, pass from said roll back over rolls 46 and 47, and then turn about a
tension roll 48, and up to the roll 16.
The folded edge of the paper having been entered between the tapes 31 and
roll 30 in the manner above described, the paper is drawn out of the carrier,
turned about the roll 30, and, as it is advanced from between the roll 30 and
the tapes 31, is received between the side plates a, b, of a second carrier 50.
This carrier is mounted and operated in a similar manner to carrier 20, being
pivotally supported by arms 51 carried by a rock shaft 52, and having its rear
end sliding in a slotted bar 53, pivoted at its ends, so as to form rocking guides
for the carrier, whereby, when the shaft 52 is rocked, the forward end of the
carrier is first moved transversely, the guides rocking as the carrier moves, and
then the carrier is moved forward longitudinally in the guides, as described
in connection with carrier 20, and as shewn in full lines in Figure 4.
The shaft 52 is rocked to actuate the carrier 50 by means similar to those
by which the shaft 22 is rocked to actuate the carrier 20. The shaft 52 has
an arm 56 provided with an antifriction roll 55, which runs on the edge of a cam
disk 54 on the main driving shaft 100, this cam being formed to rock the shaft 52
for the advance of the carrier once for each revolution of the driving shaft,
and to hold the carrier in its delivery position while the paper is being drawn out
of the carrier, and the shaft 52 is under tension to move the carrier back to its
receiving position by means of a spring rod 57 connected to an arm 58 on the
shaft 52.
The once-folded paper is advanced into the carrier 50, until the line of the
desired fold is brought opposite the forward edge of the plate a of the carrier.
The arms 51 being then moved in the direction opposite to that indicated by
the double-headed arrow in Figure 4, the carrier will be moved from the position

page_text: shown by dotted lines in Figure 4 to that shown in full lines, the forward
edges of the side plate a of the carrier following the path indicated by the
arrow, thereby causing the part of the paper outside the carrier to be bent back
about the edge of the plate a of the carrier, by contact with the roll 32, acting
as an abutment for this purpose. Then, by the further movement of the arms 51,
the carrier will be advanced longitudinally, and the folded edge of the paper
entered between pressing and feeding devices formed by the roll 32 and a roll 59.
The paper will then be advanced between the rolls 32 and 59, twice folded,
and with one end of the wrapper extending rearwardly from the paper to form
a flap to be turned about the rearward end of the paper in the further operation
of wrapping. From the rolls 32 and 59, the paper is advanced directly into a
carrier 60, by the operation of which, this folding of the rearwardly extending
flap of the wrapper is accomplished.
The carrier 60 is formed of two sides c, d. The side c is carried by arms 61
carried by a rock shaft 62, and is preferably formed by a plate which is rigidly
secured to a rod 63 extending between the arms 61. The carrier is provided
with a stop or bottom e, mounted to move with the side c, and preferably mado
adjustable by being secured to the side plate by a screw and slot connection, as
shown. The other side of the carrier is formed of a plate carried by a rock
shaft 65, under yielding tension, by means of a coiled spring 66, to move the
side towards the side c. The side is limited in its movement toward the
side c, when the carrier is in its receiving position, by suitable means, as by the
stop e in the machine shown.
The operation of this carrier will be readily understood by reference to
Figure of the drawings, the carrier being shown in full lines in its receiving
position, and the paper having just been fed into the carrier from the rolls 32
and 59. The shaft 62 is then rocked, and the arms 61 thrown upward in the
direction of the arrow shown in Figure 4, thereby moving the side c of the
carrier, and the stop or bottom e, about the shaft 62 as a centre, to the position
shown in dotted lines in Figure 4, the flap of the wrapper being, by this opera-
tion, turned about the rear end of the paper, by an abutment suitably placed for
this purpose, the feeding roll 32 serving, in the machine shown, as such an
abutment. Then, as the carrier advances to the position shown in dotted lines
in Figure 4, the rear end of the paper, with the wrapper folded about it, will
be entered between the tapes 31 and the roll 46, and drawn out of the carrier,
and fed forward between the tapes 31 and tapes GS, passing around the rolls 46
and 47, and delivered, after passing the roll 47, to any suitable receptacle or
conveying devices as may be desired. It will be seen that the carrier, in
transferring the paper to the rolls 32, 46, moves in a path substantially longi-
tudinal of the carrier and paper therein, so that, by a simple and single move-
ment of the carrier, the folding operation is performed, and the paper advanced
longitudinally, and carried into the grasp of the rolls 32, 46.
The shaft 62 is rocked to actuate the side c of the carrier 60, by means of a
cam 69 engaging an antifriction roll 70 on an arm 71 carried by the shaft 62,
and a spring rod 72 connected to an arm 73 on the shaft 62, and acting in
opposition to the cam 69.
For the purpose of guiding and supporting the papers as they are fed into
the carriers 20 and 50, the side plates 6 of the carriers are preferably extended
forward beyond the front or folding edge of the sides a of the carriers, the
rolls 16, 30, 32, and 59, being grooved or formed in sections, and the front
edge of the sides 6 of the carriers being cut away to form fingers, which move
between the sections of the rolls.
The side plate of the carrier 60 is preferably cut away at its forward edge so
as to enter between the sections of the roll 59, thus enabling the carrier 60 to
be mounted closer to the roll 59, without danger of the papers being engaged and
obstructed by the edge of the plate c, as they are advanced into the carrier.

page_text: The side & of the carrier 60 is also cut away to form fingers, which may enter
between the sections of the roll 46.
Any suitable pasting mechanism may be employed for applying paste to
secure the rearwardly-extending flap of the wrapper to the layer of wrapper on
the paper. It is preferred to employ, however, an improved pasting mechanism
which in itself forms a part of the present invention, and a construction embody-
ing the same in the preferred form will now be described.
The feeding and pressing roll 59 is formed with a groove 80 extending longi-
tudinally of the roll, and having parallel sides, which act as guides for a paste
block or bar S1, arranged so that it may be moved in said groove radially, that
is, transversely to the surface of the roll 59. In the normal position of this
paste block S1, its outer face lies inside the periphery of the roll 59, but at the
time it is desired to apply paste to the wrapper, the block is moved outward, so
that its face will contact with the flap of the wrapper, as it passes between the
rolls 32 and 59. The paste block is then withdrawn within the periphery of
the roll 59, so that by the rotation of the roll 59, when there is no wrapper
flap in position to be pasted, the face of the paste block will not contact with,
and apply paste to, the surface of the roll 32, and will leave the normal space
between the peripheries of the rolls 59 and 32. Then, when the next paper has
been fed between the rolls 32 and 59 into the carrier 60, the paste block 81 will
be again advanced, to apply paste to the flap of the wrapper, and, after doing its
work, will be again withdrawn. Paste is supplied to the paste block 81 by a
paste roll 82, mounted to rotate in a paste reservoir 83, the paste block_being
advanced to receive the paste from the roll 82, preferable once for each advance
of the block for applying paste to the wrapper.
For the purpose of advancing the paste block for pasting the wrapper, and
for receiving paste from the roll 82, cam disks 84 are provided at either end of
the roll 59, having, in their inner faces, cam grooves 85, in which travel extended
ends 86 of the paste block 81, said cam disks 84 being preferably mounted free
to rotate on the shaft of the roll 59.
The cam grooves 85 are of such a form that, if the cams were stationary, the
paste block would be held in its normal retracted position during the greater part
of the rotation of the roll 59, and would be advanced once for each rotation of the
roll 59, and be held in its advanced position during a small portion of such
rotation.
Instead, however, of the cam disks 84 being stationary, they are caused to
rotate in the same direction as, but at a different speed from, the roll 59. In
the machine shown, the roll 59 is rotated five times for each rotation of the main
driving shaft 100, that is, five times for each paper passing between the
rolls 59 and 32, and the cam disks 84 are caused to rotate at such a relative
speed as to advance the paste block 81 once in every five revolutions of the
roll 59, in position to apply paste to a wrapper flap passing between the rolls 59
and 32, and once in every five revolutions of the roll 59 in position to receive
paste from the paste roll 82; that is, during each five revolutions of the roll 59,
the cam disks 84 are revolved three times.
There can therefore be employed a smaller roll, making a greater number of
revolutions than there are papers passing between the rolls, instead of a com--
paratively large roll to carry the paste block making only one revolution to
each paper passing between the rolls, since, as the paste block is advanced for
pasting only when a wrapper flap is passing between the rolls, no paste will at
other revolutions of the roll be applied to the other roll of the pair, or to papers
passing between the rolls.
For the purpose of ensuring the proper timing of the papers as they are
advanced to the carrier 20, there are provided stops 90 carried by a rock shaft 91
mounted below the tapes 10, 11, and actuated by a cam plate 92 on the cam
disk 54, which engages an anti-friction roll 93 on the end of a spring rod 94,
the other end of which is connected to an arm 95 on the rock-shaft 91, so as to

page_text: throw the stops 90 up into the path of the papers as they are advanced by the
tapes 10 and 11, and hold it until the proper time, when the cam allows the
shaft 91 to be rocked by the spring rod 94, to carry the stops 90 out of the path
of the paper.
The various moving parts of the machine are driven from a main driving
shaft 100, which carries the cam disks 24 and 54, by which the carriers 20 and 50,
and the stops 90, are actuated, and which also carries a large gear 101, through
which the other parts of the machine are driven as follows:-The roll 15 is
driven by means of a gear 102 on its shaft, meshing with the gear 101, and
from this gear 15, the roll 12 is driven through the tapes 14. The shaft of
the roll 12 carries a gear 103, which, meshing with a gear 104 on the shaft of
the roll 13, drives said roll 13. The shaft of the roll 16 carries a gear 105,
and is driven through an intermediate 106 meshing with the gear 105 and
the gear 101. The shaft of the roll 30 carries a gear 107, meshing with the
gear 101. The roll 32 is driven from the gear 101 through an intermediate 10%,
mesling with the gear 101, and with a gear 109 on the shaft of the roll 32, and
from this gear 109 the roll 46 is driven through intermediates 110 and 111,
meshing respectively with the gear 109 and with a gear 112 on the shaft of the
roll 46. The roll 59 is driven by means of a gear 113 on its shaft meshing
with the gear 101. The cam disks 84 are each provided with a gear 114, and
are driven by gears 115 on the shaft of the roll 32. The shaft of the paste
roll 82 carries a gear 116, which is driven from the gear 101 through an inter-
mediate 117. The cam 69, by which the shaft 62 is rocked, is driven from the
shaft of the roll 32 by means of a gear 118 on said shaft, meshing with a
gear 119 carried by said cam.
The wrapper-feeding rolls 38 and 39 carry intermeshing gears 120 and 121,
and are driven from the gear 112 on the shaft of the roll 46, through a train of
gears, 122, 123, 124, and 125, the gear 125 meshing with a gear 126 on the
shaft of the roll 39. The feeding rolls 34 and 35 carry intermeshing gears 128
and 129, and are driven from the gear 126 through an intermediate 130 mounted
free to turn on the shaft of the roll 37, and meshing with the gear 126, and with
a gear 131 on the shaft of the roll 35. The severing rolls 37 and 36 also carry
intermeshing gears 132 and 133, and are driven by a small gear 134 carried by
the gear 135, and meshing with a large gear 135 on the shaft of the roll 37.
The gearing is properly timed, so that the papers will be fed into the carriers,
and the carriers actuated at the proper times for folding and wrapping the
papers, as hereinbefore described.
Referring now to the feeding mechanisms, and more particularly to that form
of the said mechanisms illustrated in Figures 7 to 15, inclusive, the frame which
supports the-operative parts is indicated at A', and this frame is intended to be
located in proper proximity to the wrapping mechanism. The parts which con-
stitute the feeding mechanism may, however, if desired, be suitably supported
in the frame A of the wrapping mechanism. The frame A is formed to provide
ways A upon which reciprocates a carriage C, which is formed by suitable side
bars C, cross bars C, and carries two sets of longitudinal bars C, C. This
carriage is preferably provided with rollers C. The frame A' is provided with
standards B, which are connected by cross bars B. The standards have con-
nected to them, by means of slots and set screws, or in any other suitable manner,
supports B2, which carry uprights B³. The cross-bars B₁ before referred to,
carry similar uprights B3, the whole forming a frame for retaining the pile
or stack of articles in position to be acted upon by the feeding devices. The
carriage C before referred to reciprocates beneath this pile-retaining frame.
In that form of the construction shown in Figures 7, to 15, the carriage C
is provided with a rack C, which engages a toothed segment.1), mounted upon
This rock arm
a rock arm D', suitably journaled in the frame of the machine.
is connected by a rock arm E to a crank stud F' on a crank disk F, mounted
on a shaft F, which is also suitably journaled in the frame. The shaft F' is

page_text: provided with a gear wheel F, which meshes with a gear wheel G¹ on the main
shaft G. The main shaft is rotated by any suitable source of power, and, when
so rotated, it will be seen that the carriage will be reciprocated beneath the
pile-retaining frame before described, by means of the devices just described.
In the carriage C is journaled a shaft H.
The shaft H carries a series of grooved pullies H¹, and is provided, on one of
its ends, with a gear wheel H, which engages a rack H. shown in Figures 7
and 15, mounted on the pile-retaining frame before described. To each of the
grooved pulleys H₁ is connected one of a series of tapes or bands I, the other end
of these tapes or bands being connected to a bar K, which is mounted on the
standards B of the pile-retaining frame, the arrangement being such, that
the tapes pass beneath the pile retaining frame, and between it and the
bars of the carriage, and therefore act to support the pile of articles
contained in the pile-retaining frame. It is obvious that as the carriage recipro-
cates, the shaft H will be revolved, by reason of the engagment of the gear He
with the rack H³, and the tapes or bands I will be wound on, and unwound from,
the grooved pulleys before referred to, and that when they are unwound they
will, as stated above serve as the support for the pile of papers, pamphlets books
or other similar articles.
Passing through the grooved pulleys H¹ is a shaft L carrying bent hooks L'
This shaft carries, at one end, a disk M7, which is provided with a stop plate M,
having a pair of stops M1 M² (see dotted lines in Figs. 11 and 12), which engage
with a suitably mounted stop pin M³. The stop plate M is further provided
with a pin M, to which is connected a spring Me, the other end of the spring
being connected to a pin on the disk M, mounted on the shaft H before referred
to. The spring M" is so arranged that, when the shaft L is rocked by the means
hereinafter to be described, and the pin M5 passes the centre in either direction,
the spring will assist in the rocking movement, and hold the shaft reliably in
position, with one of the stops M, M, against the stop pin M³.
The opposite end of the shaft L is provided with a collar N, from which
projects a pair of arms N1, Nº. These arms are staggered or offset, as shown,
and engage with suitable projections 0, 0, the projection being mounted in
the frame A of the feeding mechanism, and the projection 01 being mounted
on the travelling carriage. As the carriage is reciprocated, and the shaft H
and its connected parts rotated, as hereinbefore described, the arms N, N2, will
strike the projections 0, 0, before referred to, and the shaft L will be rocked
thereby.
Extending across the carriage C, near, one of its ends, is a bar P. On this
bar Pis mounted a drum R. Within the drum, and surrounding the bar, is a
spring S, one end of which is connected to the bar P and the other end of
which is connected to the drum R. The drum R is preferably constructed to
form a series of broad-faced pulleys R', herein shown as three in number, but
it is, of course, obvious that as many of these pulleys may be provided as is
deemed necessary or desirable. Upon these pulleys are wound a series of broad
tapes or supporting bands 1, one end of each of these bands being connected
to each of the pulleys R¹ before described, and the other end being connected
to a stationary bar K², which is mounted in the frame. It is obvious that as
the carriage is reciprocated in one direction, the broad supportg. bands or
tapes will be first unwound from the pulleys R' against the tension of the
spring, and then rewound thereon by the action of the spring, as the carriage
returns.
Extending across the carriage, and mounted therein, is a bar T, this bar being
located between the grooved pulleys H¹ and the broad pulleys R. This bar T
is provided with a series of bridge pieces T¹, the purpose of which will be
hereinafter described.
Beneath the path of the reciprocating carriage is a series of tapes U. These
tapes are mounted upon suitable pulleys U1, U2, one set of which may be

page_text: driven in any suitable or desired manner. The tapes are arranged to deliver to
the tapes 11, which have been before described as carrying the papers to the
wrapping machine. In addition to the stopping mechanism 90, which forms a
part of the wrapping mechanism proper, there may be also provided a suitable
paper-controlling mechanism, which acts to retain the papers on the tapes U.
In the present instance, an ordinary drop-roll mechanism, such as is well known
in the art, is shown in dotted lines in Figures 7 and 8, and co-operates with the
tapes U. It is to be understood, however, that this mechanism may be omitted,
or the stopping mechanism 90 may be omitted, if desired.
Any ordinary belt-tightening mechanism may be used with the tapes U, such
a mechanism being indicated at U
The operation of this modification of the feeding mechanism is as follows:-
Referring to Figure 7, it will be understood that the carriage has completed
its movement toward the left of the observer, and is about to reciprocate to the
right, thereby removing a sheet from the pile in the pile-retaining frame.
Immediately before the carriage completes its movement to the left, the arm N2
has been caused by the rotation of the shaft H, under the influence of the gear H³
and the rack H³, to strike the projection O¹, which is mounted in the carriage.
This has rocked the shaft L, and caused the bent retaining pins L', the ends of
which are bent towards the pile in the retaining frame, to take over the edge
of the lowest paper or article in the retaining frame. The sheet is thereby held
at its edge between the pins and the circumference of the grooved pulleys H'.
As the carriage starts upon its return movement, the sheet, being held at its
edge as before stated, is bent down and carried around by the pulleys H¹, which
are being rotated by reason of the engagement of the gear H2 with the rack H³.
At the same time, the supporting tapes I begin to be wound up on the grooved
pulleys, and therefore begin to pass out from under the pile.
As the carriage continues its movement to the right, the tapes I are pro-
gressively withdrawn from under the pile, and, at the same time, the bridge and
guiding pieces T, come under the forward edge of the pile, and temporarily
support it.
The further movement of the carriage causes the suppporting bands I³, which
have begun to be unwound from the drum R¹, to come into position, where they
also act to support the pile. When the carriage has reached the proper point
in its reciprocation, and the shaft H has reached the proper point in its rotation,
the arm N will be brought in contact with the projection O, mounted on the
frame. The shaft L will then be rocked in the direction opposite to that in
which it was rocked before, and the bent hooks L' will be withdrawn from the
top of the sheet. The sheet will now, however, continue to be fed by the
frictional action of the grooved pulleys before referred to, and as soon as its
head reaches the upper stretch of the tapes U, is will be carried ahead by these
tapes, the several parts assuming the position indicated in Figure 8.
When the carriage has completed its movement to the right, at which time
the pile in the rotary frame will be wholly supported by the bands I and the
bridge pieces T, the sheet will have been entirely detached from the pile, and
will be fed ahead by the tapes against the stops of the drop-roll mechanism
before referred to. At the proper time, these stops are withdrawn, and the sheet
will pass to the tapes 11, and be by them delivered to the wrapping machine,
or any other suitable machine.
The carriage having finished its reciprocation to the right, then starts upon
its return. The supporting bands I will now be rewound upon the drums R',
thus ceasing to act to support the pile of sheets, and the supporting bands or
tapes I will be unwound from the grooved pulleys H¹, and will again support
the pile. Just as the carriage is about to complete its movement to the left,
the rocking of the shaft L is effected in the manner before referred to, and, at
the instant of the completion of the movement of the carriage in this direction,

page_text: the bent hooks have laid hold of the edge of the next sheet, preparatory to
causing its removal in the manner herein before described.
Referring to the modification of the feeding mechanism illustrated in Figures 16
to 20, inclusive, it will be understood that the construction, in the main, is
similar to that which has just been described. In this modification, however,
the carriage C, instead of being reciprocated by the rack and gear mechanism,
has connected thereto a rod 200, which is connected to a crank arm 201, mounted
on a shaft 202, carrying a gear 20, the shaft being revolved from a gear 203
mounted on a shaft 204; there being a suitable intermediate 205 between the
gears 206 and 203. The gear 203 may be driven from any suitable mechanism,
and it is obvious that, as it is driven, the carriage C will be given forward and
backward movements, which correspond to the movements produced by the rack
and segment mechanism used in connection with the modification of the feeding
mechanism hereinbefore described.
The flexible tapes or bands I, and the mechanism for operating them, are
omitted in this modification, and the pile of papers or other articles in the
pile-retaining frame, is alternately supported by the slats C, C³. The ends of
these slats are brought much nearer together than in the modification previously
déscribed, and the sheet-detaching device is located in the space between them.
The slats (C³ are either made sufficiently narrow, so that their ends will pass
into the groove in the grooved pulleys H¹, or the ends of the slats may be
sharpened off, so that they will enter these grooves. Furthermore, the collar N,
instead of being provided with two staggered arms, is, in this case, provided
with a single arm N1, which alternately contacts with the stops O and O¹.
-
is
The operation of this modification will be readily understood from the descrip-
tion which has been given of the operation of the construction which
illustrated in Figures 7 to 15, inclusive. As the carriage C reciprocates to and
fro by reason of the operation of the crank mechanism before described, the
pins on the detaching roll will be caused to seize the sheet or other article,
and draw it down through the space between the slats C, C³. As the sheet
is withdrawn, the slats come under the front edge of the pile, and act to
progressively support the same, while the slats C progressively retreat, thus
permitting the sheet to be peeled from the under side of the pile.
In this modification of the feeding mechanism, it will be noted that the
reciprocation of the carriage and the pile-supporting devices not only act to
detach the sheet or paper from the pile, but the constant movement to and fro
under the pile, acts to shake up or agitate the pile, and thus tends to overcome
the tendency of the individual sheets or papers to adhere to one another, which
action, of course, materially assists in the sheet-detaching operation.
Referring to that branch of the invention which is embodied in the wrapping
mechanisin, and the parts pertinent thereto, it will be understood that the features
of that branch of the invention, as hereinafter set forth in the claims, may be
embodied in machines differing widely from that shown and described for the
purpose of illustrating the invention as embodied in a complete folding and
wrapping machine, and that the construction of the various features of the
invention claimed may be varied without departing from the invention.
It will also be understood that the devices described herein as employed for
folding over the flap of the wrapper, may be used also for folding a paper or
other article not associated with a wrapper, and such use is within the invention.
While this branch of the invention has been described as especially applicable
to wrapping newspapers and other publications, it will be understood that
machines embodying it may be used for wrapping or folding, or folding and
wrapping, other articles to which it may be found applicable, and that such
uses are within the claims, the term paper" being used in the claims to
include all articles and materials on which the machine is adapted to
operate.

page_text: While, furthermore, that branch of the invention which relates to the feeding
mechanisms has been described in connection with, and is primarily intended to
be used for, feeding folded papers magazines, pamphlets, and similar articles to
wrapping machines, it has, of course, a far wider application, and in capable
of use in many other relations. It is not, therefore, to be restricted to the
described use, and it is to be understood that the term "sheet" which is used
in the claims covering this branch of the invention, is not to be given a restricted
signification, but is intended to cover generically any article capable of being
acted upon by the detaching devices.
It is also to be understood that this branch of the invention is not to be
restricted to the particular mechanisms or devices employed to effect the several
operations, as many modifications are possible. For instance, while the pins
which hold the papers or other articles to be fed to the detaching rolls form an
effective means for this purpose, may other devices may be used. So, too, the
pile-supporting devices may be varied within wide limits, and the same is true
of the other parts of the apparatus. While, also, it is desirable, in many cases,
to feed from the bottom of a pile of papers, sheets &c., it is also obvious that,
with slight changes, the apparatus is capable of taking sheets from the top of
a pile, in which case, of course, the pile would be supported otherwise than by
the pile supports, which in that case would operate only to assist the detaching
devices in their action.
In general, it is to be understood that the invention which forms the subject
of this application is not to be limited to the specific details of construction
which have been described for carrying it into effect, as these details in all the
mechanisms may be widely varied."
