In constructing this machine my correspondents have endeavoured to make
the mechanism as simple and effective as possible and have arranged it so that
there shall be absolutely no handling from the time that the pile of blanks is first
placed in the machine until the box or pail is discharged complete in every
respect.
In this machine the pile of blanks is placed on top of an elevator operated by
mechanism which will raise the pile as required to keep the top blauk in reach of

page_text: the picker. This picker is designed to raise the top blank and place it upon a
carrier so operated by mechanism that the instant the blank is placed upon it it
travels to a point where printing mechanism is placed and which is timed to print
and instantly release the blank so that it may be conveyed by the carrier to a point
where the plunger is arranged to instantly come down upon the blank and force it
through folding cams into a position where mechanism is located to form and clasp
a wide bail onto the box or pail which at this period is complete and is then nested
with preceding pails and forced into the discharge spout.
In the drawings like letters of reference indicate similar parts in the different
figures.
A represents the main driving shaft from which all moving parts of the machine
derive their motion.
As the first motion referred to is that of the picker, its construction and the
manner of its operation will be first explained.
B represents a hollow crank shaft suitably journalled on the frame of the
machine, as indicated, and provided with an arm C, which is connected by the
rod D, to the shaft A', as indicated in Fig. 2. On this shaft a cam E is fixed
which in revolving with the shaft A' comes in contact with a friction roller located
on the bottom of the rod D forcing the said rod down so as to cause the crank
shaft B to rock in its bearings. F is a spring to act on the arm C and cause it to
move in the opposite direction to that in which it is forced by the action of the
cam E. On the hollow crank shaft B is fixed a hollow finger G communicating
with the interior of the shaft B. A solid head H is also connected to the end of
the finger G, as shown in Fig. 2 and for the purpose hereinafter explained. The
hollow crank shaft B is connected to an air pump I operated by a cam J and
spring J which acts against the plunger rod K of the air pump I and is so timed
that the plunger of the pump is acted upon by the spring J' (see Fig. 6) so as to
quickly exhaust the air in the shaft and finger G the instant that the mouth of
the finger G comes in contact with the top blank. By operating the plunger by a
spring Ja quick motion is secured which quickly exhausts the air and makes the
picker work more effectually than it would if the plunger was worked slowly. On
reference to Fig. 6 it will be seen that simple means for adjusting the tension of
the spring J is provided and consists of a sleeve K'screwed upon the rod K. The
cam J is fixed to the shaft A' which is geared to the main shaft A as shown in
Fig. 1. When the air is exhausted from the finger G the top blank is raised by
the upward movement of the said finger, the operating mechanism of which is so
timed as to elevate the blank at the time that the carrier is moved by its mechanism
below the blank so raised. As the mechanism continues to move, the plunger of
the pump is carried in the reverse direction so as to force the air back into the
finger G and in this way the blank held by the said arm is permitted to drop into
the carrier L.
In order to prevent the hollow finger G raising more than one blank at a time a pair
of fingers is provided, shown in Figs. 3 and 4, which fingers have crooked ends which
lap over and rest upon the pile of blanks as shown in Fig. 4. When the finger G
raises the top blank it draws its edge from below the hooked ends of the said
fingers 88 which remain on top of the blanks and prevent the next one being raised
until the finger comes in actual contact with it.
With the view of preventing the blank being carried against the impression
plate Z, a curved guard 89 provided which directs below the impression plate Z,
any blank which might be accidentally raised above the carrier L.
As the blanks are removed from the pile which rests on the table G¹ it is
necessary that simple mechanism should be provided for the purpose of automatically
elevating the said table so as to keep the top blank within reach of the finger G.
With that view (see Fig. 2) there is fixed on the shaft B an arm P' having a hooked
end Q adjustably connected to it and shaped so as to engage with the head N
formed on the upper end of the bar M'. This bar M' is held to the frame O' by
the screws R' which pass through elongated holes in the bar M' so that the said

page_text: bar may be moved vertically without disturbing its connection with the frame O¹.
As the shaft B is rocked so as to bring H in contact with the pile of blanks the
hooked end Q' moves away from the position close to the neck of the head N¹
which it occupies when the finger G is elevated and permits the bar M' to drop
slightly by its own gravity but the head N¹ of the said bar M' never looses contact
with the arm P¹ consequently as the shaft B rocks a reciprocating vertical motion
is given to the bar M.
V is a disc fixed to the spindle V1 and U₁is a cog ring journalled on the disk V'
in such a manner that it will revolve freely on the said disc if revolved in one
direction while if turned in the opposite direction, it will be frictionally connected.
Any of the well known friction clutches may be adapted for this purpose. So well
known a device is therefore not illustrated.
S¹ is an arm pivotted in its centre on the spindle V₁ and at one end to the
vertically adjustable arm M'. T¹ is a pawl pivotted on the end of the arm S¹ and
designed to engage with one of the teeth in the toothed ring U. The reciprocating
movement of the bar M¹ imparts a rocking movement to the arm S and the friction
connection between the disc V' and the cog ring U₁ is such that when the bar M¹
moves down, the pawl T¹ moves the cog ring U₁ a given distance without affecting
the disc V2 or its spindle V₁ but when the bar M' moves up, a friction connection
is formed between the ring U' and its disc V2 consequently the spindle V₁ moves a
given distance. This spindle V₁ is suitably journalled on the frame O₁ and has
fixed to it a pinion or gears with a rack formed on the back of the slide W', (see
Fig. 1) on which the table G' is fixed, therefore the said movement of the ring U₁
will correspondingly elevate the table G¹ and as the blanks are carried on this table
they are raised the required distance to keep them in contact with the head H on
the finger G. In order to prevent the elevator table G¹ from falling while the
wheel U¹ is moving to get a fresh grip of the dise V², a tooth wheel U2 (see Fig. 1)
is provided which is journalled on a disc connected to the spindle V' and a pawl T²
is provided pivotted on the frame of the elevator and designed to engage with one
of the teeth of the wheel U2. The disc on which the wheel U2 is journalled
revolves freely while the spindle V' is revolved by the action of the disc V² but the
moment that the frictional connection between the disc V2 and its ring U¹ is broken
the spindle V₁ is prevented revolving by its disc forming a frictional connection
with the wheel U2. Y¹ is an arm pivotted on the frame O¹ so that it may fall
between the rings U₁ and U2. On the end of the arm Y' projecting pins are formed
so as to be in front of the pawls T1 and T2. When the arm Y¹ is in the position
shown in Fig. 2, the pawl T' is permitted to move the short distance required to
accomplish its purpose but by pressing the lever Y' down, the pins projecting from
it will force the pawls T' and T2 up clear of their respective cog wheels leaving the
spindle V free to be revolved by hand.
The carrier L is supported in suitable guides M and is operated by an arm N
(see Fig. 1) which is fixed to the rock shaft O. This rock-shaft is provided with
à crank-arm P to which a suitable rod Q is attached which rod extends back to the
main shaft A and is arranged to derive a longitudinal motion by the action of the
cam R which is fixed to the shaft A as shown in Fig. 1. An elongated hole is made
in the crank arm P at the point where the rod Q connects. This oblong hole is for
the purpose of adjusting the rod and crank so as to shorten or lengthen the crank
with the view of altering the movement of the arm N by which the carrier Lis
operated. A spring connected at one end to the crank arm P and at the other end
to one of the arms 69 supporting the gearing which drives the shaft A' returns the
carrier L after it has been thrown forward by the action of the cam R. When the
carrier L passes below the blank the adjustable hook S, one of which is fixed to
each side of the carrier (see Fig. 3)-passes the edge of the blank so that when the
carrier is moved back the hook S comes in contact with the blank and holds it in
position on the carrier. In order to hold the blank in exactly the proper position
to be printed, two fingers T are provided, connected to the rock-shaft U which is
operated by a rod V connected at its upper end to the rock-shaft U the lower end

page_text: carrying a friction roller in contact with cam W connected to the end of the
revolving shaft X. The driving mechanism by which the rock-shaft is operated is
so timed that the fingers T shall be in the path of the blank on the carrier L when
the caid carrier has conveyed the said blank to the proper position to be printed
(see Fig. 25). In this way the blank is held in exactly the proper position by
means of the gravity stops Y and fingers T. The instant that the printing is
completed the fingers T are raised by the action of their mechanism so as to leave
the path clear for the passage of the blank which is then fed to the folder.
It will be observed that there are two sets of adjustable hooks S on the carrier L
one set being at the end of the carrier, while the other set is located near its middle,
the end set being located as shown in Fig. 3 at the point ready to remove the blank
from the picker while the other set is located at the printing device. By this
arrangement the carrier L conveys a blank from the picker to the printer and
simultaneously conveys the blank from the printer to the folder. As there will be
a preceding blank at the printer at the time that the carrier returns for a fresh
blank from the printer it is necessary to provide means to prevent the carrier
conveying the said blank away from the printer. With that view gravity stops Y
are provided, pivotted in the guide 67 (see Fig. 25) which stops will drop in
front of the blank when the carrier L commences to move forward and thus
hold the blank stationary while the carrier is returning.
On reference to Figs. 1, 5, 7, 8, 9 and 19 the construction and operation of the
printing mechanism will be understood.
Z is the platen held rigidly to the frame of the machine as indicated in Fig. 1.
Immediately below the impression block, a type-bed a is located on which the type
is held. A longitudinally moving rod bis hinged to the type-bed a (see Fig. 5) and
after passing through a guiding bracket 86 rests upon and is supported by the cam d
fixed to the shaft A. The friction roller e is placed on the end of the rod b. The
mechanism shown and which gives motion to the rod is so timed that at the proper
moment when the blank should be printed the type-bed a is moved up so as to
cause its type to act upon the blank. The shaft X, already referred to, derives its
motion from the main shaft A through the vertical shaft which is arranged as
shown in Fig. 19. A bevelled pinion g is fixed to the shaft X and meshes with a
pinion fixed to the shaft which extends to and is geared with the shaft i which as
shown in Fig. 7, is geared to the inking rollers j. On reference to this figure it
will be observed that there is a double-ended ink font k. The rollers m which
distribute the ink on their ink roller j derive a longitudinal motion by means of the
pivotted lever n (see Fig. 9) the ends of which are provided with pins to fit into the
grooved rollers 85 fixed to the spindle of each distributing roller m. The pivot pin
of this lever has a crank o fixed to it which crank is connected to and operated by
the camp which is fixed to and revolves with the shaft i.
The ink is conveyed from the font rollers 57 to the rollers by the rollers 58.
Each end of the rollers 58 is journal!ed on a crank arm 78 on the shaft 59. At one
end the shaft 59 projects and has fixed to it the crank arm 79 having a projecting
friction roller 80 designed to engage with the cam disc 60 which in revolving
carries the arm 79, over so as to move the roller 58 from the roller 57 to the
roller while the spring 61 moves it back. The other side of the cam disc 60
engages with a friction roller projecting from the slide 62 which is supported on a
stud 83 and the projecting end 81 of the spindle of the roller 57 on which a ratchet
wheel 64 is fixed. A pawl 63 is pivotted on the slide 62 and engages with the
ratchet wheel 64. As the cam disc. 60 revolves it pushes the slide 62 against the
spring 65 which spring pushes the slide back as the formation of the cam disc 60
permits. As the pawl 63 engages with the ratchet 64 the said ratchet wheel 64
must revolve causing the font roller 57 to gather ink from the font k. The
mechanism is timed so that the roller 57 is revolving when the roller 58 comes in
contact with it. As the distance which the roller 57 revolves depends upon the
number of teeth which the pawl 63 passes over and as this is regulated by the
length of travel of the slide 62 an adjustable stop 66 is provided which comes in.

page_text: contact with a projection 84 on the slide 62 thus limiting the backward motion
thereof so that the cam disc 60 shall have more or less effect on the slide 62 as may
be desired. In this way the quantity of ink to be gathered by the roller 57 may be
regulated.
The rollers 9 which distribute the ink over the face of the type are suitably
supported as indicated in Fig. 7, by the guide bars and are operated by rods s
(see Fig. 1) which are pivotally connected at one end to the spindles of the
rollers and at their other end to the rocking arm t which is supported in a suitable
bearing formed in the frame of the machine as indicated in Fig. 1 and has a crank u
fixed to it which crank is designed to engage with the cam which is geared to and
operated by the shaft A as, indicated in Fig. I and is so shaped that it will impart
the necessary rocking movement to the rocking arm t as is required to cause the
rollers to travel backwards. and forwards at the proper intervals across the face of
the type supported on the platen a taking ink first from one roller ; then from the
other moving only once for each impression.
On reference to Figs. 1, 10, 11, 12, 13, 19 and 26 the construction and operation
of the folding device will be understood.
The fingers 10ª which project from the cross-bar of the frame of the carrier
form a support to assist in carrying the blank below the plunger x. These fingers
are curved slightly upwardly so as to better accomplish their purpose.
In Fig. 1 is shown two downwardly curved plates 10 fixed to the frame of the
carrier one in front of and the other behind the plunger . In Fig. 26 are shown
four plates 10 arranged one on each side of the plunger forming a rectangular
opening corresponding to the shape of the plunger. These plates are intended for
the purpose of supporting and steadying the blank as it is being formed into shape.
In Fig. 1 as stated only two plates are shown, while in Fig. 26 four are shown.
The latter figure my correspondents think show the preferable plan. It may also
be mentioned here that all the guide bars 67 are perfectly straight in Fig. 1 while
in Fig. 26 the upper ones are curved outwardly at the point opposite to the side
plates 10. It may be mentioned that the blanks while being conveyed on the
carrier are between two guide bars 67 on each side and in practice it has been
found that the end flaps of the blank projecting between the bars bend up against
the top bar while the plunger is forcing the blank down and the upper bar has
therefore been curved outwardly (as shown in Fig. 26) so that it will not present
any obstruction to the end flap of the blank while the said blank is being forced
down by the plunger. When the plunger x forces the blank through the space
formed by the plates 10 it forces it between the folding cam w (see Figs. 1, 10
and 11). These folding cams are geared together at right angles to one another
(see Fig. 11) and are shaped so that when they are set in the position indicated in
Figs. 10 and 11 they shall form a rectangular opening corresponding in shape and
size to the box they are intended to fold. These folding cams derive motion from
the shaft X and their operating mechanism is so timed that they will act against
and fold the blank into the shape indicated in Fig. 10 as the plunger forces the
blank between them. This plunger is connected to a crosshead y which is con-
nected to and supported by the vertical rods z. (Only one rod z is shown in
Fig. 1.) Each rod is operated by a cam 2 which is fixed to and revolves with
the main shaft A. When the plunger & forces the blank between the cam rollers w
the blank is made in the shape indicated in Fig. 12 with flaps 31 at opposite
corners. On the top of the plunger are adjustably connected four plates which
may be made to project more or less over the edges of the plunger x each plate
having a knife edge against which the cams w press the sides of the pail or box at
the base of the flaps so as to crease the box and make the flaps easy to fold. In
order to fold over the flaps 33' and complete the box two rollers 4 are placed
immediately below the folding cams w. Each of these rollers is provided with two
spiral flanges 5 the proper distance apart to correspond with the size of the
plunger x. The rollers 4 make one revolution as the box is forced between them
and they derive this motion by means of the rack 6 (see Fig. 1) which meshes with.

page_text: pinions 7 fixed to the ends of the rollers 4. The rack 6 has a rod 8 which extends
to the shaft A (see Fig. 1) and is driven by the cam 9 fixed to the said shaft.

On reference to Fig. 12 a finger 76 will be seen which projects towards the
plunger and is designed to pass below the flap 31 and hold it back while its
opposite flap is folded below it. This finger 76 thus ensures the perfect folding
of the flaps. A similar finger is of course provided on the other side.
By the action of the plunger a in forcing the blank between the rollers w and
rollers 4 the box or pail is folded into perfect shape and by the time that the
plunger is ready to return, the box is in the position to receive its wire bail.
On reference to Figs. 14, 15, 16, 17, 18, 19 and 27 the construction and
operation of the bailing mechanism will be understood. When the form of the
box is complete as just described, the plunger a remains stationary during the
period that the bailing mechanism is in operation. The wire 11 (see Figs. 14
and 16) lies in a groove made in the stationary plate 12, the said groove being
extended through the wings 13 which are hinged to the plate 12 as shown in
Fig. 16. Two sliding bars 23 are each provided with a lug 21 to which a rod 20
is connected the other end of the said rod being connected to the rock shaft 22
(see Fig. 27) which in turn is connected to and operated by the rod 24 connected
to and operated by the cam 25 fixed to the main driving shaft A. Each of the
wings 13 is connected by a rod 14 to the cross-head 15 which is connected to the
rock-shaft 17 by the rod 16 (see Fig. 27). This rock shaft 17 is connected by
the rod 18 to the cam 19 connected to and operated by the main shaft A. A
spring 72 connected to an arm on the rock shaft returns the shaft and its
connections to their normal position. The cams 19 and 25 are arranged to operate
their connecting mechanism in the following manner.
When the plunger x is holding the recently formed box in the rectangular hole
formed in the plate 12 the rock shaft 22 is caused to move so as to draw the sliding
bars 23 in the direction indicated by arrow (see Figs. 14 and 15). This movement
bends the ends of the wire 11 around the lugs 26 shown in section in Fig. 16 and
which are formed upon the spring plates 27. Simultaneously with this the wire is
cut off by the movement of the said sliding bars. Each bar 23 has a recess 23"
formed in it only one of which is shown (see Fig. 16) the other one being hid by
the tube 70.
The wire after it comes from the feed rollers 47 and 48 (described farther on)
passes through a round tube 68 (see Figs. 15 and 16) screwed at one end into the
lug 69 and at the other into the square tube 70. This tube butts against the
hardened steel cutter attached to the sliding bar 23 and they together form a pair
of shears to cut the wire. The interior of the tube 70 is tapered to the edge of
the said sliding bar 23 and when the bar is moved the wire is cut at the point of
junction. The square tube 70 is adjusted against the sliding bar 23 by revolving
the tube 68 which has a thread of coarser pitch in the lug 69 than in the tube 70.
When the bars 23 begin to move in one direction indicated by arrow the wire is
cut off and the wire lying in the recesses is bent around the lugs 26 to form the
ends of the bail intended to penetrate the sides of the box. If the recesses were
merely a groove large enough to contain the wire the moving of the bars 23 would
merely shear off the end of the wire, but as the rear of the recess is rounded away
as shown it allows the wire to be drawn out and bent around lug 26 as described.
By the time that the ends of the wire have been bent at right angles around
the lugs 26 the wedge-shaped lifter 28 attached to the ends of the bars 23 has
entered underneath the spring plate 27 and raised it so as to move its lugs 26 clear
of the path of the bent wire 11. At this moment the rock-shaft 17 moves so as
to cause the wings 13 to move and fold the wire around the box held by the
plunger a forcing the ends of the wire through the sides of the box where they
are bent and clinched by coming in contact with the surface of a curved recess
formed in a plate projecting through a slot made in the plunger (see Fig. 18)
the said plate being actuated by a spring so that it will yield slightly when the
wire strikes it. It may be mentioned here that the wire 11 is held in its groove

page_text: through the plate 12 by a movable plate 29. This plate is held in position over
the said wire (see Fig. 14) by the action of two bell cranks 30 one being located
at each of its ends. Each bell-crank is held as shown in this figure by the rod 14
while the wings 13 are in their initial position. As soon as the rods 14 commence
to move, the wings 13 cause them to swing outwardly, gradually increasing the
distance between the rods 14 so that by the time the wings have moved half their
backward travel the pressure is removed from the bell-cranks 30 and leaving the
plate 29 free to be pushed clear of the wire groove by the action of its spring 31..
In this way the wire bail is left free to move when the box has been properly
bailed. At this point the spring fingers 32 are raised so as to clip over the top.
edge of the finished box 33 (see Fig. 29) and the plunger commences to move up.
leaving the box free to be conveyed down by the fingers 32 into the chute or
discharge spout 34. On reference to Figs. 1, 28, and 29 the manner of operating
the fingers 32 will be understood. The cam 35 which is fixed to the shaft A is.
arranged to act upon the bell-crank wiper 36 which in turn is connected by the
vertical rod 37 to the pivotted rod 38 which is connected to the cross-head 39 to
which the fingers 32 are attached. The cam 35 is of course shaped and timed so.
as to produce the desired motion at the period mentioned.
A spring 73 is attached to the rod 37 the other end being secured to the frame of
the machine and acts against the rod 38 to keep the fingers 32 up when not drawn
down by the action of the cam 35.
In order to ensure the proper nesting of the boxes two downwardly projecting
guide-rods 71 are attached to the plate 12 of the bailer just inside the groove
holding the wire bail so that as the pails are drawn from the plunger the wire bails
are on one side of the rods and the pails on the other thus preventing the bails
interfering with the proper nesting of the pails.
The boxes are prevented from falling down as they are stripped from the plunger
by the spring fingers 32 by the action of the guide rods 71 and the rods 72 attached
to the bailer on the other side of the opening grip the boxes between them and
prevent them moving downward except as they are forced by each new box as it is.
nested into them.
The wire 11 may be fed in continuously by any simple known form of mechanism
but as it is possible that a blank may occasionally be missed as it is not desirable
that a bail should be formed except when the box is in position to receive it, the
following simple mechanism is provided by which the wire is fed in only when there.
is a box ready to receive the bail.
On reference to Figs. 19, 20, 21, 22, 23, 24, the mechanism for feeding the wire
will be understood. In Fig. 19 a toothed segment 40 is shown. This toothed
segment pivotted at 41 and meshes with a pinion 42 which is loosely journalled on.
the spindle 43. The other end of the segment 40 is connected by the post 44 to the
horizontal rod 45 which derives longitudinal reciprocating movement from the
cam 46 which is fixed to and revolves with the shaft X. In this way the segment
is rocking continuously on its pivot during the operation of the machine and
consequently the pinion 42 is caused to revolve first in one direction and then in the
other. The spindle 43 on which the pinion 42 revolves freely is connected to the
feed-roller 47 which is geared to the feed roller 48. and between which the wire.
passes. 49 is a spring pawl pivotted on a projection connected to the pinion 42.
50 is an arm fixed to and projecting from the spindle 43. 51 is a spring plate which
in its normal position is in the path of the spring pawl 49 and holds the said spring
pawl clear of the flange 52 formed on the end of the arm 50 (see Fig. 23) and it
follows that as long as the spring plate 51 is in its normal position the spring-
pawl 49 cannot form a connection with the arm 50 and consequently the pinion 42
moves backwards and forwards without operating the spindle 43. 53 (see Fig. 19).
is a rod connected at its bottom end to the spring plate 51 and at its top to the bell--
crank 54. The other arm of this bell-crank 54 is connected by a rod 55 to a
crank arm connected to a pivotted finger 56 which lies in the path of the blank.
It will be noticed that a finger 56 is pivotted on each side of the carrier. The bell-.

page_text: crank 54 is connected to a shaft 68 and to the crank arm on the other end of this
shaft is connected to the rod 55 from the crank-arm of the other finger 56. When
the blank comes in contact with the fingers 56 it rocks them on their pivots and this
motion is conveyed to the bell-crank 54 which rocks on its pivot and raises the
rod 53 so as to lift the spring plate 51 clear of the spring pawl 49. This pawl
instantly springs out and butts against the flange 52 thus forming a connection
between the pinion 42 and the spindle 43 which spindle revolves one revolution and
by moving the feed-rollers 47 and 48 forces the necessary wire into the bailer. The
moment that the blank is clear of the finger 56, the spring plate 51 returns into the
path of the spring pawl 49 holding it clear of the arm 50 until the next blank
operates on the finger 56.
With the view of adjusting the distance between the feed-rollers 47 and 48 that
part of the spindle on which said roller 48 revolves, is made eccentric, so that by
