I, JOSEPII ALEXANDRE LOUIS BARBIER-DUROZIER, of St. Marcellin (Isère), in
the Republic of France, Engineer, do hereby declare the nature of this invention
to be as follows:-
i
This invention relates to a machine for wrapping up newspapers, books,
circulars and the like.
According to my said invention the improved machine comprises a plate upon
which is arranged a pile of wrappers of suitable size for the printed matter which
they are intended to surround individually. This plate is mounted upon the
upper portion of a screw-threaded rod entering a nut which is supported by a
cross-piece of the frame of the machine; the said nut which is free to rotate upon
itself but not to become displaced vertically, comprises at its periphery a toothed
crown or worm wheel which gears with an endless screw to which motion is
imparted from the main shaft by means of helicoidal gear-wheels, or in any
other suitable manner. Owing to this the plate is constantly raised and this
vertical movement is regulated according to the thickness of the wrappers and
also according to the rapidity of the operations to which the said wrappers are
submitted.
Above the plate and towards its extremities, are provided two boxes or
receptacles filled with an adhesive substance the oblique bottom of which, in the
form of a register capable of regulation allows a certain quantity of such adhesive
substance to pass or ooze through. Normally these boxes bear lightly upon the
pile of wrappers and the adhesive substance which they allow to pass causes the
upper wrapper on the heap to adhere thereto, in such a manner that when they
are subsequently raised, they carry with them the said top wrapper and separate
it from the remainder of the pile. Each of the boxes or receptacles is suspended
from a rod passed through a cross piece which is rigidly connected with a frame
formed of two rods and two cross-pieces. The rods pass through sockets which
serve as guides for them; the cross-pieces are attached to the cross pieces of the
suspension rods by means of a sleeve which enables the interval between the
boxes to be regulated as desired, and each of the lower cross-pieces comprises a
roller engaging in the fork of a pivoted lever provided with a roller in contact
with a cam rigidly fixed upon the principal shaft. Under the influence of the
wrapper lifting cams the two boxes are raised simultaneously, and carry with
them the paper wrappers which adheres thereto, as above stated. It should be
noticed that the boxes in redescending in the manner hereinafter explained, rest

page_text: upon the heap of wrappers, whilst compressing to a greater or less extent spiral
springs passed upon the suspension rods which have free play, in their respective
cross-pieces. The spiral springs serve as regulators.
Upon one side of the wrapper supporting plate is arranged a tablet comprising
a horizontal portion and an inclined portion which latter is adjusted in obliquely
arranged slides. This tablet supported by levers, which are rigidly connected
with an axis provided with an arm furnished with a roller resting upon a tablet
operating cam rigidly fixed upon the main shaft. Under the influence of this
cam and of the inclination of the slides, the tablet passes from its position of
repose to its operative position that is to say, it enters between the heap of
wrappers and the wrapper raised by the lifter boxes. In this position it serves
as a support for the lifted wrapper, and thus enables the package which it is
desired to surround with a wrapper to be placed upon this latter. It should be
noticed that the upward displacement of the boxes is such that the lifted wrapper
extends slightly beyond the level of the tablet and that it will fall under the
weight of the printed matter which has been placed in position; the extremities
of the wrapper which adhere to the boxes remain raised, that is to say in a suit-
able position for being finally turned down upon the printed matter which the
wrapper is to surround. Behind the boxes are arranged rollers intended to
approach each other towards the centre of the machine, the effect of these rollers
being to produce the turning down in question. Each of these rollers is passed
upon an axis supported by rods capable of sliding in sockets which are adapted
to oscillate upon supports. The axis of each of the rollers is, in addition, attached
by a connection to the upper extremity of a pivoted folder lever and provided
with a roller which is in contact with a folder cam rigidly fixed upon the main
shaft. Under the influence of the folder cams the rollers adyance towards the
centre of the machine, whilst remaining free to oscillate around the pivot of the
sockets. This oscillation is necessary by reason of the various thicknesses of
the packets of printed matter which may be required to be wrapped up. The
folder cams are attached in such a manner that one folding roller advances first
and the other folding roller advances only at the moment at which the first roller
retires. The first roller in its advance detaches from the box the projecting
extremity of the wrapper which is adhering thereto, turns it down upon the
packet and sticks it slightly upon the same owing to the point or strip of adhesive
substance which it carried with it; the second roller produces the same effect
upon the extremity of the wrapper which is adhering to the opposite box with
this difference that it sticks this extremity upon that previously turned down.
The pressure of the turning down and sticking rollers is exerted upon the tablet
which serves as a support both for the wrapper and the packet. In their travel
towards the centre of the machine the folding rollers act respectively upon
fingers or clips which they press down upon the packet for the purpose of retain-
ing it in position whilst the extremities of the wrapper are being turned down
and stuck. The fingers in question are arranged upon each side of the lifting
boxes and under the action of small springs tending to turn them down con-
stantly towards the centre of the machine, that is to say upon the packet; each
of the fingers is provided with a tail with which the axis of the corresponding
folding roller engages, of which axis they follow the movement. When these
rollers advance towards the centre of the machine, the fingers, being acted upon
by their springs, are applied upon the packet and maintain it upon each side of
the wrapper; when, upon the other hand, these rollers recede from the centre,
they act upon the said tails and the fingers are raised.
In any event it follows from the foregoing that the packet is perfectly wrapped
up and that the wrapper is at the same time stuck and adheres to the packet in
such a manner as not again to become detached. It is then necessary to remove
the packet so made up in order to enable the operation above described to be
repeated. It is at this moment that the cam again acts upon the tablet in
order to cause it to resume its initial position. In this movement the tablet

page_text: carries with it the wrapped up packet, and the boxes under the influence of their
respective wrapper-lifting camis are depressed in the direction of the pile of
wrappers so as to remove the top wrapper as above described.
One of the extremities of the made up packet conveyed upon the tablet, rests
upon a rotating roller which causes it to turn over upon an inclined plane which
conducts it towards a receptacle or receiving box provided for the reception of
the made up packets. The roller is caused to rotate by means of a small endless
cord passing over the grooved pulleys arranged upon the main shaft and the axis
of the said roller respectively.
The receptacle for the made-up packets consists of a prismatic box which is
rigidly fixed upon a pivot upon which is attached the internal extremity of a
spiral spring, the outer extremity of which is attached to a fixed barrel mounted
upon a suitable support. Tension is produced in the spring in the ordinary
manner by acting upon the square portion of the pivot. To the prismatic box
is rigidly fixed a crown which fits upon the barrel and the exterior of which is
provided with two projections arranged diametrically opposite each other. One
of these projections strikes against a finger and serves to maintain the box or
receptacle in a fixed position. The finger forms one with a slide provided with
a stud which is applied, under the influence of a spring, against the edge of a
disc provided with a notch and keyed to the lower extremity of a vertical shaft
which is driven, in a pre-determined ratio, by the main shaft by means of trans-
mission gear. The ratio of these parts is such that the shaft completes one
revolution for each twenty five revolutions, for example, of the main shaft. It
results from this that upon each twenty-fifth revolution of this shaft, the notch
of the disc is presented to the finger which engages therein, thus releasing the
projection of the crown of the said box or receptacle, which, under these con-
ditions and under the influence of the spring, turns upon itself to be again locked
by the finger. This box after having effected a half revolution upon itself con-
tinues to receive the made up packets, and then again effects a half revolution,
and so on in succession. It follows from this that the packets are piled one
upon the other in heaps of 25 and that the pile formed by them in absolutely
regular. It should be understood that the number 25 is taken by way of example
only and that the box may be caused to oscillate when 20, 30, 40, or any other
desired number of packets have been made up. The disengagement of the finger
may be utilised for actuating a device registering the number of packets made
up. When the receiving box is filled to the desired extent the packets are with-
drawn, and to effect this it is only necessary to turn down one of its sides, which
is hinged and provided with a catch with this object.
Such is the construction and operation as a whole and in its details of the
machine for wrapping up circulars or the like which I have devised, and which
it will of course be understood may be constructed in any dimensions and with-
out any exact limitation as to the arrangement of details and accessories or
with respect to any of the methods of transmission which have been described
with the sole object of rendering the fundamental principle of the said machine
comprehensible. It should finally be stated that the frame of the machine some-
what closely resembles that of a sewing machine, that upon the frame is arranged
a table top in which are formed suitable apertures for the movements of the parts
and of the wrappers and circulars or the like, and that the main shaft is pro-
vided with fast and loose pulleys for the purpose of driving from the motor and
with a hand wheel for starting and regulating the machine.

page_text: Improvements in Machines for Wrapping Up Circulars, Newspapers,
Books, and the like.
I, JOSEPH ALEXANDRE LOUIS BARBIER-DUROZIER, of St. Marcellin (Isère), in
the Republic of France, 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:-
This invention relates to machines for wrapping up circulars, newspapers, books
and the like.
In the accompanying drawings I have shown how my said invention may be
conveniently and advantageously carried into practice and in which,
Figure 1 is a vertical longitudinal section taken upon the line 1-1 of
Figure 3.
Figure 2 is a vertical cross-section taken upon the line 2-2 of Figure 3.
Figure 3 is a plan view of the machine as seen from above.
Figure 4 is a detail view of one of the parts of the machine, and
Figures 5, 6, 7 and 8 are detail views serving to explain the operation.
Upon a plate a is placed a pile of bands or wrappers of a size suited to that
of the printed matter which they are intended to individually surround. This
plate is mounted at the upper portion of a screw threaded rod at engaged in a
nut supported by a cross-piece of the frame work B of the machine; the
said nut is free to rotate upon itself but not to be displaced in a vertical direction.
It comprises at its periphery a toothed crown or worm wheel bengaging with an
endless screw or worm 1 to which movement is imparted from the main shaft A
by means of helicoidal gear wheels 2 and 3 or in any other suitable manner.
Owing to this the plate a is constantly carried upwards, and this vertical move-
ment is regulated in accordance with the thickness of the paper bands or wrappers
and also according to the rapidity of the operations to which the said bands are
submitted.
Above the plate a, in proximity to its extremities, are arranged two cylindrical
boxes C, C¹ filled with adhesive substance, and of which the bottom, which may
be in the form of the mouth of a whistle, is perforated (Figure 4) in such a
manner as to permit of the passage of the said adhesive substance. In each of
these boxes is arranged a piston c connected by means of a rod and a cross-
piece with a screw threaded rod c upon which is screwed a nut ct the periphery
of which is provided with oblique teeth adapted to come into contact with and be
actuated by a finger or pawl The finger in question is pivoted upon a
support in such a manner as to be normally maintained in a horizontal position
so that it is situated in the field of the above mentioned teeth and acts upon them
when the box is depressed, as is hereafter explained, whilst it rises automatically in
order to permit of the passage of the said teeth when the box is raised, again falling
automatically. It will be noticed that as a result of cach lifting of the box the
finger causes the nut to rotate to the extent of one tooth, and that in its
turn this latter produces the displacement of the screw threaded rod by an
amount which is a function of the number of teeth on the nut and of the thread
of the screw threaded rod c, that is to say an infinitesimal quantity which, by
means of the cross-piece 2 and the rod c¹ is transmitted to the pistone so as to
cause an exceedingly small quantity of adhesive material to flow out through the
perforations at the base of the box C. Normally the boxes C, C¹ rest slightly
upon the pile of bands and the adhesive material issuing from them causes the
upper band of the pile to adhere thereto, in such a manner that, when they are

page_text: finally raised, they carry with them the said topmost band, separating it from
the remainder of the pile. In order to prevent the lifting of several bands at
the same time, there is arranged upon each side of the pile a small and light
brush e which rubs against the edge of the pile and detaches or separates the
bands which would otherwise have a tendency to rise simultaneously. In this
manner absolute security against the lifting of more than one band at a time is
obtained. Each of the boxes C C is passed into a collar & rigidly attached to a
frame formed of two rods f f and two cross-pieces y h. The rods f f and f¹ fl
traverse the sockets f which act as guides for them; the cross-pieces g g are
respectively connected with the collars d by means of a sleeve which enables
the separation of the boxes C C to be regulated automatically. The lower cross-
pieces each comprise a roller engaged by the fork of a lever D) pivoted at i
and provided with a roller j in contact with a cam E (Figures 1 and 7) rigidly
fixed upon the main shaft A. Under the influence of the cams EE, the two
boxes and C₁ are raised simultaneously and carry with them (Figure 5) the
band of paper adhering thereto, as above stated. It should be noticed that the
boxes CC, as is hereinafter explained, in redescending actuate the small driving
mechanism for their pistons for the purpose of causing a fresh quantity of
adhesive material to issue, as above stated, and then rest upon the pile of bands
in such a manner as to seize the topmost band upon the pile a.
cam e
Upon one side of the plate a is arranged (Figure 2) a tablet F comprising a
horizontal and an oblique portion and which is adjusted in obliquely arranged
slides, k. This tablet is supported by the levers G G rigidly attached to an
axis provided with an arm upon which is fitted a roller bearing upon an
cam H (Figures 1 and 8) rigidly fixed upon the main shaft A. Under the
influence of the cam H and owing to the inclination of the slides kk, the
tablet passes from its position of repose (Figure 2) to its operative position
(Figures 7 and 8) that is to say it takes up a position between the pile of bands a
and the band raised by the lifter boxes CC₁. In this position it serves as a
support for the raised band and enables the printed matter which it is intended
to enclose to be placed upon it. The printed matter may be placed upon the
tablet F by hand or by means of the mechanical device represented in the draw-
ing. This device consists of a pallet rigidly attached to an axis e provided
with a pinion engaging with a rack et suitably guided and pivoted upon a lever e
which is itself pivoted at ef and comprises a roller in contact with a
rigidly fixed upon a shaft driven by the main shaft. A by means of an endless
chain or in any other suitable manner. From this shaft is driven, by means
of a chain for example, a roller f2 upon which a cylinder ƒ³ travels merely by
frictional contact. Behind the roller and the cylinder f is arranged a receiving
tablet Fintended for the reception of the matter which has been wrapped up.
The printed matter to be dealt with is introduced successively between the
roller and the cylinder f³ which directs it towards the pallet e upon which
each circular or the like falls, striking against a flange on the same (Figure 8).
At this moment, the said pallet, by means of the came, the rack e and the
pinion carried by the shaft 3 turns down in front carrying with it the circular
which is upon it and which it turns down upon the tablet (Figure 7). When
this has been effected, the pallet e resumes its normal position for the reception
of another circular. It will be noticed that the displacement in an upward
direction of the boxes C C is such that the lifted band passes slightly beyond
the level of the tablet F and that it should fall thereon under the weight of the
circular or the like y which has been placed in position; nevertheless, the
extremities of the band which adhere to the boxes C C remain closed, that is to
say in a position adapted for being ultimately turned down upon the circular
which the band is intended to enclose. Behind the boxes C Care arranged
rollers II intended to approach each other towards the centre of the machine and
of which the effect is to produce the turning down in question. Each of these
rollers is passed upon an axis supported by rods m m³ capable of sliding in
y

page_text: n
sockets n n which are adapted to oscillate upon supports oo. The axis of each
of the rollers II is in addition attached, by means of a link p, to the upper
extremity of a lever J pivoted at q q' and provided with a rollers in contact with
a cam K rigidly fixed upon the main shaft A. Under the influence of these
cams K K the rollers I I¹ advance towards the centre of the machine, whilst at
the same time remaining free to oscillate around the pivot of the sockets
and. This oscillation is necessary by reason of the various thicknesses of
the printed matter which it may be desired to wrap. The cams KK' are fixed
in relative positions such that the roller I advances first, the roller I advancing
only when the roller I retires. The roller I in advancing detaches from the
box C the projecting extremity of the band which adheres thereto, turns it down
upon the printed matter (Figure 6) and sticks it slightly upon this latter owing
to the strip of gum which it carries with it; the roller I produces the same
effect upon the extremity of the band which adheres to the box C¹ with this
difference that it sticks this extremity upon that which has been previously
turned down. The pressure of the turning down and sticking rollers I I' is
exerted upon the tablet F serving as a support for the wrapper and for the printed
matter. In their travel towards the centre of the machine the rollers II' act
respectively upon pincers tt and t₁ which they turn down upon the printed
matter y for the purpose of maintaining it in place during the turning down and
sticking of the extremities of the band or wrapper. The pliers in question are
arranged upon each side of the lifter boxes C C and under the influence of small
springs tending to constantly turn them down in the direction of the centre of
the machine, that is to say "upon the circular or the like; each of the pliers is
formed with a tail piece which engages with the axis of the corresponding
roller II in the movement of which they participate. When these rollers
advance towards the centre of the machine, the pliers being acted upon by their
springs, are applied upon the circular and maintain it upon each side of the
wrapper when, on the other hand, these rollers retire, they act upon the said
tails and the pliers rise.
It either case it follows, from what has been stated, that the circular is
wrapped in a perfect manner and that the wrapper is stuck together whilst at the
same time adhering to the circular, from which it cannot become detached. It
is now necessary to remove the circular which has thus been wrapped in order
that the operations which have been described may be repeated. It is at this
moment that the cam H again acts upon the tablet Fin order to cause it to
resume its initial position. At this moment the tablet F carries with it the
circular which has been wrappered, and the boxes C C₁, under the influence of
their respective cams E E', descend in the direction of the pile of wrappers a in
order to subsequently remove the topmost wrapper, as above stated.
Before the boxes C¹ descends, a T-shaped bar f, mounted upon a lever f³
actuated by a cam f6, strikes upon the edge of the wrappered circular in such a
manner as to cause it to slide upon the tablet F and engage its opposite edge
between two rotating cylinders gand g which convey it upon an endless band
which surrounds both the cylinder and another cylinder situated above a
receptacle M into which the package falls and is stacked. The cylinders g
mutually act one upon the other by means of an endless cord, the cylinder
being rigidly fixed upon the above mentioned shaft e8.
The receptacle for the wrappered circulars consists of a prismatic box M rigidly
attached to a pivot to which is attached the inner extremity of a spiral
spring R, the outer extremity of which is fixed to a fixed barrel p mounted upon
a suitable support. The tension of the spring R is obtained, in the ordinary
manner, by acting upon the square end of the pivot p². To the box M is rigidly
attached a crown q which fits upon the barrel and of which the external
portion is provided with two projections 23 diametrically opposed one to the
other. One of these projections strikes against a finger and serves to main-
tain the box or receptacle M in a fixed position. The finger q³ forms part of a

page_text: slide provided with a stud t³ which bears, under the influence of a spring,
against the edge of a disc to formed with a notch and rigidly fixed at the lower
extremity of a vertical shaft V, at a predetermined ratio, by the main shaft A
by means of the transmission parts b2b dee. The ratio of these parts is
such that the shaft V makes one revolution, for example, for 25 revolutions of
the main shaft A. It follows from this that every 25 revolutions of this shaft,
the notch of the disc is presented to the finger which engages therein, thus
releasing the projections of the crown of the box M, which, under these
conditions and under the influence of the spring R, rotates upon itself, where-
upon it is again locked by the finger g³. This box, after having thus performed
one half of a revolution upon itself, continues to receive the wrappered circulars
and again effects one half a revolution, and so on in succession. It follows from
this that the circulars are piled up into packets of 25 and that the pile which
they form is absolutely regular. It will of course be understood that the
figure 25 is taken by way of example only and that the box may oscillate, if
desired, when 20, 30 40 or any other desired number of circulars has been
wrappered. The release of the finger q may be utilised for the actuation of a
counter registering the number of circulars wrappered. When the box M has
been filled to the desired extent the circulars are removed therefrom, and for
this purpose it is only necessary to let down one of the sides which is mounted
upon hinges and retained by means of a latch.
Such as a whole and in its details of construction and operation is my improved
machine for wrappering printed matter, although of course I reserve the right to
construct it of any size without limiting myself in an express or absolute manner
to its exact disposition as regards details and accessories, nor to any of the methods
of transmission described which are given for the sole purpose of rendering the
general operation of the said machine comprehensible. I will conclude by
stating that the framework B of the machine bears considerable resemblance to
that of a sewing machine, that this framework is mounted upon a table T formed
with suitable apertures for the working of the parts and the placing in position.
of the wrappers and circulars or the like, and that the main shaft A is provided
with fixed and loose pulleys P and P¹ for power driving and with a hand wheel ()
for the starting and regulation of the machine.
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
