COMPLETE SPECIFICATION.
Improvements in the Manufacture of Stringed Labels and the like.
I, ARTHUR JEROME EDDY, of Rookery Building, Chicago, Illinois, United
States of America, Lawyer, 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:-
My invention relates to improvement in machines for supplying tags with their
tying medium, whether of string or wire, for attaching them to the articles to
be tagged. My object is to provide mechanism, for the purpose stated, of generally
improved construction which will operate to securely fasten the tying medium
upon its tag further, to provide such mechanism in combination with tag forming
mechanism, in a single machine, to co-operate therewith, in forming completed and
strung" tags from a continuous web of the tag material: further to combine
the tying medium applying mechanism with a printing press as well as tag-
forming mechanism, in a single machine, whereby tags, printed and strung, may
be manufactured from a continuous automatically fed web of the tag material, in
one machine.
My object is still further to provide mechanism for the above-named stringing
purpose, which, whether acting singly or in combination with other mechanism,
shall operate to perform its function with great exactness and rapidity.
My invention is particularly, though not necessarily, designed for "stringing"
the tags in which the tying medium is looped through the eye and secured in
place by a staple, which passes through the body portion of the tag between the
eye and adjacent end and embraces the tying medium on both sides of the tag.
While my improved stringing mechanism is particularly designed for use in
stringing tags, as stated, it may be employed for providing a card or sheet of
any description with a tying medium for attaching it to another object.
The drawings illustrate my improved stringing mechanism upon a machine
provided with a printing press and washer applying mechanism.

A is the frame of the machine of which A and A² are the supports. The top of
the frame is formed with two top rails A3 and A which extend parallel with each
other longitudinally of the frame. A drive shaft B is mounted in bearings on the
supports A' A' and at its end carries a friction disk B. On the end of the
frame A is journaled a power shaft B², extending at a right angle to the shaft B
and carrying an adjustable friction pulley B³ and a power pulley B.
Also upon
the frame A is shipper mechanism, controlled by a handle 135, which may be
operated to throw the pulley B³ into and out of frictional engagement with the face
of the disk B' to produce or stop rotation of the shaft B. The frame C of the
stringer mechanism is mounted upon a sliding support C which rests at opposite
ends on the rails A' A'. On the underside of the rails is a sliding companion
bar for the support C¹ connected with the latter by a hand screw w'. The bar to
slides with the support and the two may be caused to clamp the rails between
them, by turning the screw to, to hold the support firmly in adjusted position.
The frame C comprises two side-frames s s¹ corresponding in shape, and formed
with horizontally extending U-shaped top portions, respectively, having the
backward extending parts
The sides are held in fixed relation by
suitable cross braces so, and stationary shafts and . Upon the frame C is a
loose cross-bar C² at which the frame is clamped to the support C by a screw C³.
On loosening the screw the frame C may be slid to a limited extent longitudinally
upon the support C', in a direction cross-wise of the inain frame A, for purposes of
adjustment. D is a short horizontal shaft, journaled in brackets t t on the frame C,
and carrying between the brackets a gear-wheel D' which meshes with a gear-
wheel B on the shaft B. Beyond the brackets the shaft D, carries at opposite
ends, respectively, disks D2 and D³.
Fulcrumed at one end on the shaft s' is a rocking-lever r, having a downward
extending branch arm r', pivotally connected by means of a rod or pitman 2 with
the disk D³, at r.
Fulcrumed between its ends upon the shaft is a lever, pivotally connected,
at its outer end portion, by means of a rod or pit nan y', with the disk D2 at .
A rocking lever p, is fulcrumed on the shafts, and it has an upward extending
branch arm at which it is pivotally connected by means of a rod or pitman p
with the disk D2 at .
Fulcrumed upon the shaft is a bell-crank lever o pivotally connected at the
end of its lower arm by means of a link of with the disk D³ at a.
་

page_text: The points are diametrically opposite each other across the common center
of the disks D2 D³, whereby, owing to the natures of their connections with the
disks, the free ends of the levers q will rise as the free ends of the levers po
descend.
On the lever and pivoted thereto, between its ends, at 3, is a rocking frame or
lever n, which at its end n' is provided with an opening at which it is pivotally
connected by means of an oscillating pin n² with the extension of the frame C.
The pin passes loosely through the opening in the end of the lever n, and
beyond the lever it is provided with a nut against which the said end n' is normally
pressed by a spring confined upon the pin, as shown. The lever n carries a tubular
guide for the string (or wire) Y, and secured to its free end is a laterally
extending block (see Figure 6) having an eye a through it for the passage of
the string. Extending from the block n at opposite sides of the eye n³ are two
narrow strips n of springy metal, which, at their free ends, form blunt points,
clamping the string between them, and they operate as a needle to guide the end
of the string through the eye of the tag to be strung, as hereinafter described.
the upper side of the tube n³ is an opening into which a spring ³, mounted on
the tube, extends to bear against the string and operate as a clutch to prevent the
string from being drawn in the reverse direction from any cause. On the free end
of the lever is a block m (see Figure 10) carrying a pair of laterally projecting
snips m, pivoted together and to the block mat m². On the block m, pivoted
thereto at m³, is a lever m, which extends at its end m (see Figure 11) beyond the
side of the block. The arms of the suips are pivotally connected, respectively,
with the lever m at opposite sides of the pivot of the latter, by links m m.
The jaws of the snips are opened and closed by operating the lever m² from its
end m³.
"
In
On the free end of the lever p is a block or arm ³ (see Figure 7) provided at
its end with a finger p which is rigid upon the block and affords one jaw of a string
gripping mechanism; and, also upon the block p³, is a projection extending
parallel with the finger Fulcrumed between its ends upon the block at p, is a
lever p' one arm of which extends at the side of the arm pt, to afford the second
jaw of the said gripping mechanism, and it is pressed, normally against the first
named jaw, by a spring p, confined between it and the projection. The opposite
arm of the lever is formed with a cam face po terminating, near the end of the
arm, in a notch p Pivoted at p upon the block p³ is a lever extending at
one end against the face p of the lever p' and provided at its opposite end with a
laterally projecting pin p¹³ Movement of the lever p, on its pivot p", in one
direction, causes its end to slide along the face 7 of the lever p7, until it enters the
notch, and swing the opposite end of the lever p', against the resistance of the
spring p, away from the finger pt and thus open the jaws of the gripper. The jaws
are held open until the lever p¹² is released from the notch p10 when the jaws close
by the action of the spring ps.
In the lower part of the frame C is a horizontal shaft k (Figures 2 and 3)
having its bearings in brackets on the sides. Pivoted upon the shaft k is a
link pivotally connected at its free end with the lower end of a rod k³, which at
its upper end is bent to the form shown in Figure 7 to afford a bearing for two
forward projecting slotted string-clamping and tensioning strips i i¹. The tension
strips are adjustably secured to the bearing k by a nut-bolt and are provided
on adjacent edges with angular laterally-extending guide projections ³, (see
Figure 6). On the rod ³, near its end-portion 4, is a finger or stop-projection
which extends across the path of the pin 13 on the lever p2, to strike the latter in
the upward forward movement of the parts as hereinafter described. The rod k
is pivotally connected to the lever, at pls, by a link ; and 7 is a toggle-lever
pivoted, at the end of one arm to the lever p, at p14, (see Figure 2) and, at the end
of its other arm, to the link 4, at . The toggle-lever carries a laterally pro-
jecting stop kº (see Figure 7) for the pin p³ on the lever p¹² to strike against in the
downward backward movement of the parts.

page_text: The mechanisms carried by the levers rp and the rod ³ operate to insert and
draw the string through the eye of the tag, until the proper lengths of the string
extend from opposite sides of the eye; sever the string from the supply, and
position the string by drawing the lengths ont parallel with each other and in line
with the tag so that they may be fastened together by the stapling mechanism to
be hereinafter described.
The web of tag material is caused by the intermittent feed-mechanism, H,
to travel and stop when an eye, already formed in the web and reinforced by
washers, arrives in position; and the operation of the string applying mechanism,
thus far described, is as follows :
"
As the lever swings downward the lever swings with it and, owing to its link
connection,, with the frame C, rocks forward on its pivot ³, causing its forward
end carrying the needle to move more rapidly than the adjacent end of the
lever which carries the snips m'. The jaws of the snips are open and the end of
the needle passes between them, as shown in Figure 6.
"'
While the lever is descending, as described, the lever p swings upward, causing
the rod to be rocked forward on its pivot, k, and reciprocate the tension clamps
into the forward position shown in Figures 6 and 7. The clamps are of springy
metal, and bear normally against each other. On the frame C is a stationary
horizontal, backward-extending and pointed guide-finger or spreader, across the
opposite sides of which the projections of the clamps i pass, and which operates
to spread the clamps apart, as they near their forward positions, whereby they pass
respectively across the upper and lower surfaces of the web Z".
When the needle descends it passes a limited distance through the eye in the
web, and the slots in the clamps. The upward swing of the lever p carries the
gripping mechanism upward with the jaws open, and the latter rise on
opposite sides of the downward projecting end of the string Y. As the lever p
nears the limit of its rise, the pin p³ on the lever p2 strikes the stop-projection
on the rod, and turns the opposite end of the lever out of engagement with
the notch in the lever p, whereby the spring p drives the latter at its upper
end against the finger p and they thus clamp the end of the string tightly between
them.
In the rise of the lever and simultaneous descent of the lever p, the string pays
out through the tube 3 and is drawn through the eye in the web Z, the needle and
grippers moving at about equal speed. As the lever » is moved more rapidly than
the lever r, the needle rises from between the snips m'.
T'
?"
At the top of the side of the frame C is an upward extending plate h, (sce
Figures 10 and 14), provided on its face with a cain and a pivotal cam faced
switch, both in the positions shown and in the path of the projecting end
portion of the snips-operating lever m². The switch is held yieldingly against a
stop on the plate h, by a spring. In the descent of the lever the snips are
open and the projection passes across the side of the switch, the latter yielding
against the resistance of its spring. In the rise of the lever 7 the projection n."
slides upon the side of the switch causing the lever m² to be turned to close the
jaws of the snips and sever the string. The string is severed when the projection m
reaches the point on the switch, by which time the lower end of the needle is, in
practice, say an eighth of an inch above the snips, so that when the string has been
cut the end of the string supply projects that distance beyond the needle. When
the projection m³ strikes the can the lever m is swung in the direction to open
the snips.
At the same instant that the snips sever the string, the pin p on the
lever meets the stop on the toggle-lever k, which causes the opposite end of
the lever to slide down the side of the lever to the notch p, to open the
grippers and release the string. The downward movement of the lever swings
the rod 3 backward, and just as the snips sever and the grippers release the string,
the forward ends of the slots in the clamps pass the eye in the web and
engage the lengths of string. At the same time, the projections leave the guide
finger and spring together clamping both lengths of the string gently between
12
12

page_text: them, and sliding along the lengths, they cause the latter to extend taut across
the intervening part of the web Z, which afterwards forms the top portion of
the tag.
To prevent the clamps as they pull upon the string from drawing with it the
web and thus displacing the latter, provide the following web-clamping
mechanism: Extending downward from the upper part of the sides of the frame C
is a foot d the lower end of which is flattened and extends close to the upper surface
of the web. Reciprocating vertically in guides d¹², (see Figure 12), on the
frame C, is a rod 3, bent to the shape shown, provided at its upper end with a
head d, and at its lower end with a roller ds, which rests upon the circumferential
face of the rotating disk D². The arc of the periphery of the disk D2 is enlarged,
as shown, throughout part of the circumference to afford a cam, which, in operation,
is timed, with each rotation of the disk, to raise the rod d³ against the foot d, while
the string is being drawn, and to permit the rod to drop out of engagement with
the foot when the web is caused by its feed mechanism to travel. In order that the
rod may drop quickly when the pressure exerted against it by the cam D² is
relaxed, I provide a spring on the rod which is confined between the guide d¹ and
a collar on the rod, as shown, and operates to press the rod in the direction of
the cam.

The lever carries on its free end an angular block provided in its end with
shallow sockets (see Figure 28) which deepen gradually from end to center
and operate as hereinafter described, to clinch the ends of the staples. Projecting
from the rear side and beyond the end of the block is a V-shaped guide ²,
for the lengths of the string, as the latter are drawn taut by the tension
clamps i P.
As before stated, the strings which extend, about midway of their lengths,
through the eyes of the tags are secured in place by staples passing through the
tags between the eyes and adjacent ends of the latter and around the opposite
lengths of the string to clamp them together against the opposite sides of the tags.
The staples are formed in the machine, as required, from a continuous length of
wire, which is fed automatically to the machine, and the staples are so driven as to
straddle the strings and become clinched around the latter on the reverse side of
the tag. Following is a description of the staple forming and driving mechanism :
On the side of the frame C is an arm g, carrying brackets between which are
mounted two rotary feed rollers on shafts f2f³, respectively, which have their
bearings in the brackets. The shafts 3 carry gear wheels f f respectively,
which mesh with each other; and, on the shaft are a ratchet wheel and a
loosely mounted lever 7 carrying a spring-pawl f which engages the ratchet-
wheel. On the free end of the lever is a laterally extending pin f, which
projects into the path of a finger o² on the lever o, the said finger, in its rise,
operating to strike the pin, and turn the lever, as hereinafter described. The
lever is held normally against a stop / on the arm g, by a spring ", and
upward movement, against the resistance of the spring", of that end of the
lever, which carries the pin, causes the pawl to turn the ratchet and rotate
the rollers The roller is provided with a circumferential groove 12 (see
Figure 19) and in horizontal line with the said groove, at the point of contact, or
nearest approach, of the rollers, is a guide opening 13, through the army, for the
staple wire X. One end of the shaft, carrying the roller, extends beyond the
side of the bracket gl and rests in a socket in the end of a spring, which tends
normally to press the roller " yieldingly against the roller f. On the side of the
arm g opposite the bracket is a lever g³, pivoted to the arm gat g, and held
normally in the position shown by a spring which is confined between a lug gⓇ on
the army and the upper end of the lever. The spring presses the upper end of
the lever against a stop projecting from the arm . At its lower end the
lever carries a tongue yo the upper edge of which affords the male die-portion of
the staple forming mechanism, and extends normally in a plane just below the guide
opening 13 Above the tongue g the lever g³ is bent to provide a shoulder ".
10

page_text: Secured upon
the arm g is a bracket having an arm or plate go which extends
parallel with the adjacent surface of the arm at a distance from the latter equal to
the length of the blank or section of wire which it is desired to employ in forming
a staple. The lower end portion of the lever ³, carrying the tongue g, extends
midway between the plate g and arm g.
On the end of the lever o is a block o³, having an upward extending arm o', (see
Figure 21) which is flush with one side of the block and about half the thickness of
the latter. On the outer face of the block o³ is a longitudinal groove of (see
Figure 25) and at opposite sides of the block near its end are coincident grooves of,
which produce in the block the narrow guide neck and head of. The neck
portion of terminates at its lower end in an extension o" provided on opposite sides
with longitudinal guide ridges, for a reciprocating bifurcated block c. The forks of
the block c slide upon opposite sides of the neck and extension o³, and are
provided on their inner faces with grooves el (see Figure 26) which fit over the
guides o. The ends of the forks are provided with coincident V-shaped notches*
terminating in grooves 3. On the rear side of the block e near its upper end above
the forks is a notch Pivoted upon the arm of, at, is a lever e shaped at one
end to enter and engage the notch e in the block e and provided at its opposite end
with a laterally extending pin. A spring connected at opposite ends, respectively,
with the arm and lever e, tends normally to swing the lower or notch engaging
end forward. On the army is a stop in the path of the upper end of the block c;
and, on the frame C is a cam-faced finger g¹³, which extends across the path of the
pin c, on the lever c, to swing the latter on its pivot in the downward movement of
the lever .
In operation, as the lever o nears the upper limit of its rise, the stop projection o²
carried by the said lever, strikes the pin on the lever, and, in its further move-
ment, swings the latter upward, causing the pawl to engage and turn the ratchet-
wheel. The turning of the ratchet-wheel rotates the feed-rollers in the
direction to advance the staple-wire X, through the guide opening 13, until its end
strikes the surface of the plate go. At the same time the block e strikes the stop gl²,
and is reciprocated downward on its guide os, until engaged at its notch by the
lever co.
In the downward movement of the lever o, the lower end of the block c, at its
groove, engages the wire X and severs it at the opening 13. The further down-
ward movement of the block bends the blank, severed from the wire, across the
tongue g, to form the staple X' which, at its sides, extends in the grooves c' of the
block and is engaged at the top by the lower end of the projection o At
the moment that the staple is formed the head o, which is rounded as shown at its
lower end, strikes the shoulder g" of the lever g3 and swings the latter, against the
resistance of the spring, to move the tongue g from under the staple. In the
further descent of the lever o, the pin on the lever e slides along the cam
finger g³, which turns the lever c, against the resistance of the spring c³, out of
engagement with the notch ct of the block c, whereby the latter is free to slide on
its guide 08. When the lower end of the block c reaches the surface of the web Z,
it stops, while the continued movement of the lever o causes the block o³ to slide
in the block c, and the staple to be driven, by the projection o, through the tag.
In the meantime the lever y has swung upward carrying its block to the under
surface of the web and the V-shaped guide across opposite sides of the string to
insure the position of the latter. Thus the staple as it is driven through the web Z
straddles the opposite lengths of the string, and impinging against the block / in
the sockets l', its ends are bent over toward each other and across the under length
of the string.
It will be seen from the drawings that the various parts comprising the stringing
mechanism, independently of the stapling mechanism, are respectively secured to
the stationary frame and the levers p, in a manner to permit of their being
adjusted to a limited extent toward or away from the vertical plane of operation
of the parts comprising the stapling mechanism. As shown in the drawings the

page_text: adjustments described are rendered possible by having the blocks or arms carrying
the gripping mechanism and snips, bolted to their operating levers through elongated
slots in the latter, the needle carrying frame formed in extensible sections (see
Figure 2), and the cam-carrying plate h, secured by a bolt extending through an
elongated slot in the part of the frame (see Figure 10). By adjusting the parts
named the staple when driven may be caused to engage the string at any desired
distance from the eye of the tag.
The operations of the various parts of the mechanism described are timed by the
movements of the levers, and they act with equal precision, whether the tying
medium they provide is string or wire.
"
The term "string as used throughout this Specification is generic and includes
any other desirable flexible material, such as wire.
When my improved stringer forms one feature of a tag making machine, or tag
making and printing machine, as shown in Figure 1, the preferred arrangement of
parts is that illustrated.
The web Zo is unwound from a roll, which may be mounted between standards D
at the forward end of the machine, passes through a suitable guide E; thence
between the bed and platen of a printing-press F, which prints upon the web at
the desired locations; thence to the washer applying and eye forming mechanism, G.
Thence between the feed rollers of the web feeding mechanism, II; thence to the
stringer described and lastly to the cutting mechanism which bevels the corners
and severs the tags from the web. The feed mechanisın H is of a construction
which renders it capable of being adjusted with great exactness to regulate the
speed of travel of the web; and the various mechanisms may be adjusted toward
and from each other upon the frame A to meet the requirements for turning out
tags of any desired size.
While the construction of the stringer, shown and described is the one I prefer
to employ it will be obvious that it may be modified in various particulars
without departing from the spirit of my invention. 1 do not therefore confine
myself to the details of construction described and shown; nor, to the use of
my device upon a machine, for manufacturing blank or printed tags. My improved
device may be employed to fasten the lengths of the tying medium together, as
described, beyond the edge of the tag, instead of between the eye and adjacent
edge thereof; and I do not confine my invention to the manufacture of any
particular kind of tag.
