A Machine for Addressing Wrapped Packages and Bundling the
same.
We JAMES ALEXANDER CAMPBELL of 31 Widmer Street and WILLIAM
OSBORNE SHIELDS of 79 Bay Street, both in Toronto in the Province of Ontario
and Dominion of Canada do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
Our invention relates to a machine for printing addresses upon wrapped packages
and bundling the same, and has for its object to provide a means whereby wrapped
packages, of newspapers, for instance, may be fed for any desired length of time
consecutively to the machine, and whereby each of said packages, as it passes
upward to a table, will have an address printed upon the wrapper, and, further,
whereby the addressed packages will be laid one upon another upon a table until a
bundle of sufficient size has been formed and the bundle be wrapped with a cord,
the cord tied upon the bundle, and the completed bundle delivered to any suitable
receptacle.
The invention consists in the novel construction and combination of the several
parts, as will be hereinafter fully set forth and pointed out in the claims.
Reference is to be had to the accompanying drawings forming a part of this
Specification, in which similar figures and letters of reference indicate corresponding
parts in all the views.

At one end of the base 10 of the machine, a transverse shaft 11 is journaled, in
the upper ends of standards 12, mounted on said base, and upon said shaft a bed
cylinder 13, is securely fastened. Opposite the inner side surface of the bed
cylinder, a rotary impression cylinder 14, is located, and the shaft 15 to which it is
secured, is journaled at its extremities in movable boxes 16 and 17, capable of
lateral movement upon beds A, supported some distance above the base of the
machine by posts or standards 18. A bed A, is located near each side of the base,
and consists preferably of two parallel, longitudinal bars 19, triangular in cross
ம்.

page_text: section, the boxes moving upon the beds being provided on their under faces with
angular recesses to receive the bars.
Upon the transverse shaft 11, which is the main driving shaft, eccentrics 20
and 21 are secured, one near each end of the bed cylinder 13, as best shown in
Figure 1, the said eccentrics being connected with the boxes 16 and 17 by rods 22,
which are pivotally connected with the boxes and rigidly secured to the eccentrics.
The impression cylinder 14, is provided with a wide peripheral groove or
channel 23, the side walls of which are undercut, as illustrated, or otherwise formed
to receive the extremities of type blocks 24, and maintain said blocks in position.
Each of the type blocks preferably contains a single name and address, and
ordinarily the addresses contained upon the cylinder are of persons from one city,
one county or state.
One side face of the impression cylinder has produced thereon at or near the
periphery a number of ratchet teeth 25, one face of each tooth being inclined and
the other straight. The teeth 25, are adapted to be engaged by a dog 26, pivoted
to the base of the machine and held normally at an obtuse angle to the teeth by a
spring 27. When the impression cylinder is carried back by the eccentrics of the
main shaft the teeth readily pass the dog as the latter is forced rearward against
the tension of the spring 27; but, upon the forward movement of the impression
cylinder in direction of the bed cylinder, the dog engages with one of the teeth of
the impression cylinder sufficiently to revolve said cylinder the space of one tooth,
whereupon the block 24 formerly printed from is carried downward out of the way,
and the next block is brought into position to impress its type matter upon the
wrapper of a package in position to receive it.
The eccentric 21 upon the main shaft has a sleeve integral with its outer face,
having a clutch surface a upon its outer end; and upon the main driving shaft
between the clutch surface of the eccentric and the opposed bearing of the shaft,
a sleeve 28 is loosely mounted provided with a clutch surface a', adapted to receive
and engage with the clutch surface of the eccentric 21. The sleeve 28, has formed
thereon near its outer end an annular groove 29, adapted to receive an upright end
member of an angular shifting lever 30, which shifting lever is fulcrumed upon the
base of the machine, the inner end of the shifting lever being adapted for engage-
ment with the trip pin 31, attached to the impression cylinder upon its ratchet face.
When the impression cylinder has made a complete revolution, the pin 31, acts
upon the shifting lever 30 to throw the sleeve 28 into engagement with the clutch
section of the eccentric 21, and when this is accomplished the sleeve revolves with
the main shaft. The sleeve 28, has projected outward therefrom an arm 32, and in
the extremity of said arm is pivoted the outer end of a bar 33, which is upwardly
curved at its pivotal end, but is straight throughout the remainder of its length.
The straight portion of the bar extends horizontally in the direction of the opposite
end of the base, and the inner end of the bar is constructed in two parallel members,
spaced somewhat one from the other the upper member being provided upon its
under face with teeth forming a rack B, and the lower member constituting a guard.
The rack B of the bar 33 engages with a pinion 34 fast upon a transverse shaft 35,
journaled at its inner end in a box formed at the upper end of a standard 36, located
at the rear of the impression cylinder and at one side of the centre of the base, and
the opposite end of the shaft is journaled in a similar standard 37 located near one
side edge of the base. The shaft 35 extends beyond the standard 36 and its pro-
jecting end has attached thereto a gear wheel 38 which meshes with a toothed
segment 39 secured at its centre to a shaft 40 extending transversely across the
centre of the bed near the rear end thereof, the shaft being journalled in suitable
bearings 41 supported some distance above the base as shown in Figures 1 and 3.
The segment 39 has secured to one side a segmental rack 42 of considerably less
radius than the toothed surface of the segment proper, which rack is adapted to mesh
with a pinion 43 fast upon the inner end of a short transverse shaft 44, journalled
at its inner end in bearings supported by a standard 45 located practically opposite
the standard 36 of the shaft 35 and at its opposite end in a corresponding standard 46.

page_text: The toothed segment 39 when in its normal position extends below the base 10 of
the machine, and to that end a longitudinal opening 47 is formed in the bed, as
shown in Figures 1 and 2.
Upon the shaft 44 is keyed a bevel gear 48 which meshes with a similar gear
wheel 49 upon a longitudinal side shaft 50 revolving in suitable bearings near the
rear end of the base and provided at its rear extremity with a second bevel gear
wheel 51 meshing with a like gear wheel 52 fast upon a transverse shaft 53
journalled near the rear end of the base, in rear of the shaft 40.
The main segment 39 is adapted to support a table 54 which is inclined down-
ward in the direction of the rear of the base, being at its rear or lower end secured
to the hub of the segment, and attached to the upward forward end of the segment
at its periphery by a standard 55, bracket or its equivalent as best shown in
Figure 2.
In openings 56 and 57 formed in the forward end of the base of the machine at
or near each side thereof are journalled friction rollers 58 and 59 located one at
each side of the bed cylinder and in arms 60 projected upward and forward from
the sides of the base, friction rollers 61 are journaled in vertical alignment with
the lower friction rollers 58. In the top of the arms 60 small guide rollers 62 are
journaled the said guide rollers being practically at the rear of the friction
rollers 61 and in suitable arms or other supports extending also upward and
forward from the sides of the machine near the impression cylinder arc journaled
large friction rollers 63 and lower and smaller guide rollers 64. In arms also
carried upward from the sides of the machine near the impression cylinder, but in
the direction of the rear end, are journaled small guide rollers 65 and 66, two of the
rollers being located at each side of the machine. Beneath the forward end of the
machine at each side are journaled guide rollers 67 and 68 and above the guide
rollers 68 over the opening 57 in the base two guide rollers 69 and 70 are journaled.
All of the rollers may extend from side to side of the machine, or each side of the
machine may be provided with independent rollers as occasion may demand. An
endless carrying belt 71 passes over the upper guide roller 62 and the friction
roller 61 downward at the rear of the bed cylinder, under and in contact with the
friction roller 58, thence beneath the bed to an engagement with the friction
roller 59, upward in frout of the bed cylinder, over the intermediate upper friction
roller 63 and the upper guide roller 65 of the rear set, as shewn in Figure 1, to the
friction roller 62 again, the said belt being endless as stated. A second endless
belt 72 passes over the lower guide rollers 67 and 68 beneath the base of the
machine upward through the opening 57 in engagement with the friction roller 59
and guide roller 70, thence upward in front of the bed cylinder parallel with the
belt 71 over the upper intermediate roller 63, thence rearward and downward over
the lower of the rear guide rollers 66, thence over the intermediate guide roller 64
down parallel with the belt 71 between the guide rollers 69 and 70. It will thus
be seen that the two belts travel close together and in parallel lines beneath the
base of the machine and upward in front of the bed cylinder and horizontally to a
point just forward of and slightly above the forward end of the table 54. A set
of these belts 71 and 72 is placed at each side of the machine, the belts under no
circumstances extending from side to side, as they are adapted only to engage with
the ends of the packages to be operated upon.
In the forward edge of the table 54, at each side of its centre, is journaled a
friction pulley 73 over which pulleys and the rear shaft 53 run endless belts 74, the
table being between the upper and lower strands of the belt, as shewn in Figures 3,
5, and 7. In the table between the belts, is formed a circular opening 75 (Figures 5
and 7) surrounded by a circular casing 76 secured to the under face of the table
and extending downward therefrom. The bottom of the casing is closed, with the
exception of its central portion which is provided with an opening 77. The upper
edge of the table opening 75 is partially surrounded by a tongs-like gripping
device D (Figure 3) comprising two semi-circular jaws 78 and 79 one at each side
of the opening, each jaw being provided with a rearwardly-extending shank 80 and

page_text: the shanks being connected by a spring 81. The shank of the jaw 78 is pivoted to
the table and the inner ends of the two jaws are pivotally connected as shewn.
The gripping surface of each jaw is provided preferably with a series of spring
tongues 82. Near the table opening 75 at one forward side an L-shaped dog 83 is
pivoted against which bears a spring 84 tending to keep the head or free member of
the dog over the opening in the table, as shewn in Figure 8. In front of the gripping
device opposite the dog 83 a cutting device E is located, which may be made
scissor-shaped, as shewn in Figure 3, the handle of one blade 85 being firmly
secured to the table, while to the movable blade 86 is pivoted one end of a link 87
the opposite extremity of which is formed with a slot or eye 88 through which a
pin 89 extends, which is fast to a lever 90 fulcrumed at one extremity to the table
at the rear portion of the gripping device, as is also best shewn in Figure 3. The
lever is preferably in the shape of a bar and is provided upon its front edge, near
its free end, with a lip or spur 91 adapted to enter the space between the shanks
of the gripping device and cause the jaws to close around the table opening. The
lever is operated to produce the above action by being engaged with a vertical
post 92 secured at its lower end to the base 10 at the rear of the table, the upper
end of which post is slightly curved over the table, as shewn in Figure 5. The
engagement between the post and lever is brought about when the table is tilted
rearward through the medium of the segment 39.
The
The knotting mechanism F.is located in the casing 76 and consists primarily of
a tubular body or forming section 93 and a tubular tying section 94, both sections
having a circular exterior contour. The forming section is of such diameter that
it is capable of turning freely in the casing 76 and the diameter of the tying
section is so regulated that the said section may freely slide in the outer or forming
section. The forming section is provided with an interior spiral groove 95
extending from its top to its bottom, a semi-circular recess 96 in its upper edge,
and a hook-shaped guide 97 secured to the upper edge opposite said recess.
tying section 94 is provided near its lower end with an annular peripheral groove 98
and an exterior pin 99 on one side slightly above the groove. Near the upper end
of the tying section a recess 100 is formed in its inner face and below the recess in
the bore of the section the upper end of a spring 101 is secured, the lower end of
which spring is attached to the shank of a hook 102 which projects beyond the
bottom of the section, as shewn in Figures 7 and 9. The body or forming section
of the knotting mechanism is of such length that the recess 96 in its upper end
projects above the table when the lower end rests upon the bottom of the casing 76
as illustrated in Figure 7.
At one side of the table a jointed standard H is located the lower end of which
standard is pivoted to the base 10 of the machine, as is best shewn in Figure 5.
The standard is composed of a series of links of which the lower vertical link 103
is attached to the base. A forwardly and upwardly extending slotted bar 104 is
secured to the base of the link 103 and a second link 105 curved in the direction
of the forward edge of the link 103 is pivoted to the latter at one slotted end and
at its upper end to the lower extremity of a link 106 curved in the same direction
but to a less extent and provided upon one face with a pin 107 adapted to enter the
slot in the end of a rearwardly-curved plate 108 fast to the side of the table 54,
the said plate being adapted to act upon the links of the standard and accommodate
them to the movements of the table. A fourth link 109 practically completes the
formation of the standard, being pivoted at one end at or near the centre to the
lower curved link 105 and fitted at its lower extremity to slide in the slotted
bar 104. To the upper end of the link 103 of the standard is pivoted the lower
end of an arm 110 which is curved upward and laterally over the table, as shewn
in Figure 5, and terminates in a hook 111. The arm 110 may be considered as a
portion of the standard, as the upper end of the link 106 is pivoted thereto. The
hook of the arm 110 is adapted to horizontally support a fork 112 by entering a
sleeve 113 formed at the extremity of one of its members, the fork being held
securely attached to the arm by a set screw 114, or similar device, entering the

page_text: sleeve and engaging with the hook, as is best shewn in Figure 4. In the body of
the fork is pivoted a curved arm 115 to the forward end of which a lifting pin 116
is pivotally attached. The body of the pin is circular in cross-section and
terminates at its lower end in a conical head 117. To the under-side of the body
of the fork is pivoted one end of a horizontal rod 118, the opposite end of which
rod is curved upward and attached to a collar 119 fitted to slide upon the body of
the pin and engage with a spring latch 120 secured to the pin above the head, as is
best shewn in Figure 5. To the lower rod 118 is pivoted one extremity of a
perpendicular rod 121 whose other end is bent over the arm 115. A link 122 is
pivoted to the rear end of the arm 115, the lower end of which link is provided
with a pin adapted to slide in a longitudinal slot 123 in a curved plate 124 secured
to the table 54 and extending beneath the same.
In the table, at one side of the knotting mechanism, is loosely fitted one end of a
gauge arm 125 which is curved upward from the table transversely over the same
and then downward within a short distance thereof, as shewn at h in Figure 6, and
from the point the gauge arm is carried upward and forward at a right angle to
its body section between the belts 74. At the point the arm has secured thereto
a spring clip 126 for the reception of a binding cord 127 which is contained on a
spool or reel 128 turning beneath the table upon the base of the machine, as is best
shewn in Figure 5.
The belts 71 and 72 are revolved in any suitable manner and in operation the
wrapped packages are fed one by one to the said belts 71 and 72 at the forward
meeting faces thereof, as at M in Figure 2, and are taken upward between the bed.
and impression cylinders. As the wrapper of each package faces a type block of
the impression cylinder sustaining a central diametrical position upon the cylinder,
the eccentric connection between the main shaft aud impression cylinder is so
timed that the latter will be moved forward to an engagement with the wrapper,
and will print the name and address thereon, the back of the package resting
against the bed cylinder. After receiving the impression, the packages are carried
farther upward and rearward by the belts and are laid one on top of the other
upon the table 54 beneath the forwardly-curved end of the gauge arm 125, which
arm is pressed upward by each package as it passes beneath it, as illustrated in
Figure 2. The lower package rests upon the binding cord 127 which is passed
from its spool upward through the aperture in the table and carried some distance
rearward upon the table, the upper end of the cord being held in the spring
clip 126. The ends of the pile of packages rest upon the table belts 74.
When the impression cylinder has made a complete revolution and all of the
addressed packages have been piled upon the table, the shifting lever 30 is tripped
by the pin 31 of the impression cylinder and the rack bar 33 is thereby thrown
into gear with the main shaft, so as to impart movement to the shaft 35, and
through it to the segment 39 whereby the table is tilted upward and rearward.
The segment also imparts movement, through its rack 42, to the shaft 44 which
latter, through the medium of the side shaft 50 revolves the rear shaft 53 and sets
the table belts in motion. The moving table belts carry the bundle downward and
rearward, which causes the ends of the cords encircling the bundle to lie over the
knotting device, as shewn in Figure 7, the cord being passed over the entire bundle
by the gradual lifting of the gauge arm, the said arm being disengaged from the
bundle when the latter slides downward. At the moment the bundle passes the
knotting mechanism the first tilting movement of the table so acts upon the links
of the jointed standard H, that the lifting pin 116 is caused to enter the inner
member 94 of the knotting mechanism and the latch 120 thereof to enter the
interior recess 100 of said member. The effect of the further movement of the
table upon the jointed standard is such as to cause the pin to be withdrawn
upward therefrom, and the outer member, by reason of the outer movement of the
inner meniber, is revolved which causes the guide hook 97 of said member to
engage with the double strand of cord in front of the package, as shewn in
Figure 7, and the continued revolution of the outer member 93 of the knotting

page_text: mechanism carries the double strand of cord around its upper end, between the
said end and the jaws of the gripping device D, as shewn in Figure 8. The
strands are wound, one completely around the outer member of the knotting
mechanism and again partially around it the coil ceasing at the recess 96 in the
said member. As the inner member is drawn upward a spring upon the head of
the dog 83 is brought in engagement with the outer face of the inner member
of the knotting mechanism and compels the dog 83 to move forward against the
tension of the spring 84 but the moment that the spring upon the head of the
dog 83 disengages from the member 93 of the knotting mechanism, which happens
at the moment that the second coil of cord passes over the recess 96, the spring 84
acts and forces the head of the dog inward and the said head engaging with the
lower coil of the cord forces the said coil inward over the knotting mechanism, as
is best shewn in Figure 8. The continued upward movement of the inner
member 94 of the knotting mechanism causes the hook 102 thereof to grasp the
inwardly-projected strands of cord and the said strands are thereby drawn upward
through the completed coil and the coil from off the outer member of the knotting
mechanism whereby a complete knot is formed, as shewn in Figure 9. Just before
the table reaches the limit of its tilting movement the action upon the link 122
and the links of the jointed standard is such as to cause the pin 116 to travel
downward some distance, whereby the inner member 94 of the knotting mechanism
is again introduced into the outer member and when the inner member is so
introduced, the rods 118 and 121 are brought into action to compress the latch 120
and the pin is thereby disengaged from the inner member 94 of the knotting
mechanism and the said member drops downward to its place revolving the outer
member until it assumes its normal position. When the table has reached the
limit of its tilting movement the post 92 engages with the bar lever 90 and causes
said lever to act upon the cutting mechanism, closing the blades thereof over the
cord which passes between them and severing the said cord, whereupon the bundle
drops from the table into any suitable receptacle placed to receive it.
