'
The present invention comprehends suitable
mechanism for automatically securing a piece of
string I8 to the tag I0, this securing being effect
ed by the loop 2D on one side of the tag through 55
2
2,081,285
which, on the other side of the tag pass the free
ends of string I8, this loop securing the string to
the tag.
The machine for accomplishing this threading
operation automatically includes a pulley 22
mounted upon the shaft 24 journaled in the base
or frame 2, this pulley being rotated by means
of a belt which is driven by any suitable source
of power, such as an electric motor or the like.
10 Fixed to the shaft 24 is a sprocket 25 and a gear
28, the sprocket 2d through the chain 30 operat
ing sprockets 32 and 34, as will be hereinafter
Also disposed within the cam groove Sii is a
roller |92 connected to arm E54 which is pivoted
as at |66 to the frame or base, a second arm liìii
being operatively connectel „o the roller |02
whereby this arm is adapted to oscillate an arm
IIB connected to the shaft ¿l2 of the loop form
ing and threader mechanism 54. This shaft is
provided with the radially extending portion || 4

journaled in the frame or base 2 of the device.
This gear 36 is formed with a cam groove 4i)
in one face thereof within which is disposed a
roller 42 secured to feeder arm 44, this feeder
arm being pivoted at 45 to the frame or base 2
20 at one end and being pivotally connected at 48
to a feeder carriage 55, which carriage at its
forward end has an upwardly projecting pin 41
which is adapted to project into the opening i2
of the lowermost tag Iû in the magazine 6 and
move the same forwardly to the position shown
in Figures 1 and 3 of the drawings whereby the
openingy IZ is disposed directly beneath the nee
dle or threader 52 of loop forming and threader
mechanism generally referred to as 54. It is
understood, of course, that arm 44 oscillates in
termittently to successively transfer the lower
most tag from the magazine 6 to the position
as shown in Figures 1 and 3 to receive string
which is attached thereto, as shown in Figure
35 13 of the drawings, by the mechanism to be
hereinafter more fully disclosed.
Mounted in back of the gear 36 and upon the
shaft 38 is a cam member 56 having a cam groove
58 formed in one face thereof and a cam groove
40 59 formed in the other face thereof. Operab-le
within the cam groove 58 is a roller 66 secured
to the lowermost end of lever 62 which is ful
crumed at 64 to the frame or base 2 and to the
upper end of which, as at 10, (see Figure 8) is
pivotally secured the spaced arms 66 and 68, these
arms being normally pulled toward one another
as by means of the coil spring 12. These arms
66 and 68 straddle a bracket 14 which has an
enlarged head 16 which tends to spread these
arms apart about their pivot points 10 as the
arms move thereover due to the movement of
lever 62 about its pivot 64.
This movement of
lever 62 of course is in accordance with the cur
vature of the cam groove 58. These arms termi
nate at their upper ends in the laterally disposed
and curved points 18 adapted to engage the string
forming the loop 2D and to spread the same apart,
as will be more fully disclosed hereinafter.
Operable within the cam groove 60 is a roller
84 secured to the lower end of lever B2 which
is fulcrumed about the shaft 84 secured to the
frame or base 2 of the machine. The upper end
of the lever £2 is provided with a transversely
disposed shelf 85, upon which is mounted the
threader arms 88 and 9|? by means of the pivot
bolt 92. The lower ends of these arms 88 and
90 are connected together by means of a coil
spring 94 which tends to maintain the upper
ends of the arms in closed position and in con
tact with one another. The lower ends of the
arms have the plates 96 attached thereto which`
normally are in abutting engagement but serve
to spread the upper ends of the arms 88 and 96
apart upon their engagement with a wedge mem
ber 98 secured to the table or top 2, as at |04.
10
vides a mounting for the curved needle or thread
er 52, this needle or threader being replaceable
The chain 3G, as previously indicated, drives
the sprocket 34 of string feeding mechanism
generally referred to as 35, which is mounted
upon the bracket |32 adjustably mounted upon
the table 4 by means of bolts |33 in openings
|35 thereof.
This sprocket 34 is mounted upon
a transversely disposed shaft E22 journaled in
the bracket |32 and has a beveled pinion |24
mounted thereon adapted to drive a beveled gear
|25 mounted upon the vertically disposed shaft
iäß journaled in the bearing |34 provided in
the bracket |32. This vertically disposed shaft
|28 is formed with an eniarged head |34 dis
posed below the bearing 53€) and abutting against
the lower end thereof. This shaft E23 is ro
tated through shaft |22, pinion |24 and gear
|26, and is provided with a transversely dis
posed bore |36 adapted to receive the cylindri
cal end |33 of the string feeding or measuringr
arm |46, this arm being adjustably secured in
bore |36 by means of a set screw |42.
The arm
|45 is provided with an integral ñxed jaw E44
to which is pivoted a movable jaw |46 as at
|48, a cutting knife |56 being pivotally secured
on the pivot |48 adjacent the movable jaw |44` 40
and has its lower knife edge §52 disposed to
Cooperate with the edge |54 of the ñXed jaw
|44 to sever the string, as hereinafter to be more
fully disclosed. The pivotal jaw |45 is normally
maintained in closed relation with fixed jaw |44
by means of a coil spring |56 mounted upon a
rod |58 and disposed between abutment E66 on
the arm |40 and the upper end |512 of the Inov
able jaw |46, the rod |58 being provided with a
tapered end received within a recess in the up
per end |62 of the movable jaw whereby the rod
is loosely associated with the upper end |42 of
the mov-able jaw to permit movement of said
jaw, the rod being guided within the transverse
opening |64 of the abutment |56.
Mounted upon the table 4 is a bracket |66 hav
ing the substantially vertical supports |68 and
|10 and upon which are mounted rollers |12
and |14, respectively, substantially in the path of
movement of the movable jaw |46 and the mov 60
able cutting element |50, respectively. At one
point in the travel of the string feeding and meas
uring arm |43, the upper end |62 of the movable
jaw |46 engages roller |12 whereby the jaw is
moved away from the fixed jaw |44 about its pivot
|48 to release the string carried thereby. The
string, however, which has been carried along
during the movement of the arm |40 is disposed
in position to enter between jaws |44 and |46
when` opened, and after the upper end |62 of mov
able jaw |46 passes over roller |12 and closes
this string is grasped between jaws |44 and |46
whereby the string is again carried along, as will
be later described. The roller |14 is in the path
of the lower end of movable knife |50 and when
2,081,285
this knife engages with the roller, the same is
moved toward the edge |54 of jaw |44 to sever
the end of the forward section or length of string
which has been previously released from between
jaws |50 and |44, as will be later` described more
in detail, this movement of the knife |50 being
limited by the pin |16 fixed to the upper end |62
of the movable jaw and operable within slot |18
in the upper end of the knife.
'
The string |80, as shown in Figure 1 of the
drawings, is drawn from a suitable source'by the
string feeding and measuring arm |40 through
opening |82 formed in the top' or table 4 and
through a tensioning device |84 and around the
hook shaped guide |86. ‘The string, after being
gripped betweenA jaws |4'4‘y and |46, is drawn
through the tensioning device |84 from the source
and carried‘around pins |88Yand' |99 of the string
control means, generally referred to as |92. This
string control means comprises a plate |94 ñxed
to the top 4 of the machine and the intermediate
and top spring plates |96 and |98, respectively,
these plates being provided with spaced arms
thereof, continues to rotate from the roller |14
toward the threader or needle 52 in a circular
path. This movement continues to draw the
string |80 from the source through tension device
|84 around the guide |86 and a guide 248 located
on the table 4 substantially opposite the rollers
|12 and |14. During this movement, the tag 8
`which has been previously threaded, is discharged
from table 4 in the manner to be presently de
scribed, and the feeder carriage 50 has moved to
present another tag with its opening I2 disposed.
directly below and in the path of movement of the .
threader or needle 52. After the tag 8 has been
moved to this position, the projection 41 of. the
feeder carriage 50 drops downwardly out of en`gagement with. the opening |2 and is moved by
arm 44 beneath the magazine 6 to engage the
next tag which is to be moved into‘a position for
threading. As the feeding arm |40 continues its.
counter-clockwise movement, the string |80 suc- ~,
cessively engages protuberances 228 passing be
tween the same and the plate |94 to engage pins
|88 and |90 substantially as shown in Figure 5.

the arms thereof is secured to plate |94 by rivet
2|0 and spaced therefrom by the washer 2|2.
Intermediate the rivet 2|0 and bolts 202 and 204

tuberance 246 of the rotating head |34 engages
the protuberance 244 of plate |98 to move pins
|88 and |98 upwardly whereby the central part
of the string passes around pins 230 and 232 and
into a position to be engaged by the shoulder of
eye |20 of needle 52. The pins |88 and |90, after
disengagement of protuberances 244 and 246, re»
turn to their normal projecting position within
openings 234 and 236. The jaws continue to
move `in a circular path into a position substan

The plate |96 at the end opposite
|96 is held in association with plate |94 by means
of the coil springs V22|! intermediate the heads
of the bolts 2| 4 and 2|6 and the under side of
plate |94. Plate |94 is formed at its other end
, with openings 222 and 224 into which project the
pins |88 and |90, respectively, which are con
nected to the arms of plate |98 and pass down
45 wardly through openings 226 in the arms of plate
|96, plate |96 adjacent these openings being pro
vided with the protuberances 228 normally _held
in engagement with the plate |94 by means of
springs 220. Fixed to the arms of plate |94 are
50 pins 230 and 232 which project upwardly through
openings 234 and 236 formed in the arms of plates
|96 and |98, respectively.: Pins |88 and |90 are

ina circular path by the lever arm |08 and when
thejaws are in the vicinity of rollers |12 and |14 40
engages the central >portion of the string, as
shown in Figure 9 of the drawings. Continued
downward movement of needle 52 causes the cen
tral part of the string (which has been cut as will
be described) to be threaded through'opening l2
to form a loop on the under side of the tag 8.
After this loop has been formed, the string form
ing the loop is engaged by the laterally project
ing portion 18 vof the arms 66 and 68 and spread
apart, as shown in Figure l1 of the drawings, it
being understood that lever 62 has been operated
to move arms 66 and 68 to a position to engage the
normally disposed within the openings 222 and
224 under the action of spring plates 238 and 240,
loop and to engage wedge 16 to effect a spreading
of the loop. »These spreader arms 66 and >68
which have an end engageablewith the arms of
therefore form an enlarged loop on the under side ._
the plate |98 adjacent the pins 230 and 232 and
of the tag and` tend to `pull this loop away from
the tag, as clearly indicated in Figure 1l of the
an end secured to the bolts 202 and 204 between
the nuts 242 thereforand the upper surface of
the arms of plate |98. P_ins |88 and |90 are
60 moved upwardly out of the openings 222 and 224
of the plate |94 during certain operations of the
machine by the inner end of plate |98 which has
a protuberance 244 engaged by the protuber
ance 246 formed on the under surface of the en
larged head |34 of the shaft |28.
For the purposes of illustrating the operations
of this machine, let us assume that the string
measuring arm has passed the roller |14 and the
knife member |50 has been operated to sever a
70 portion of >string preceding the portion of string
the end of which is secured between the fixed and
movable jaws` |44 and |46.
The arm |40 is ro
tated in a counterfclockwise direction, as viewed
in Figure 2- of the drawings, and with the end of
the stringl |80 between the jaws |44 and |46
drawings.
.
It is of course understood that previo-us to the
complete formation of this loop on the under side
of the tag, the arm |40 has rotated whereby the
roller |12 has engaged the upper end |62 of the
movable jaw |46 to release the forward end of the
string |80 which has been moved in a circular
path, as above described. Immediately upon` re
lease of this end of the string, the string is again
grasped between the jaws |44 and |46 as the arm
|46 passes beyond roller |12.
'I‘he arm |00 pro
ceeds >in its counter-clockwise movement whereby
the roller |14 immediately engages knife |59 to ~
move the same and to cut the forward end por
tion of the string which is to form the loop of Fig
ure “l1 of the drawings. It isv after this cutting
operation that the threader 52l completes the loop
through the opening |2 of the tag andthe arms
.1
4
2,081,285
and 68 engage the same to form an enlarged loop
and to draw this loop away from the tag. Dur
ing the formation of the loop, lever 82 has been
moved as described, and as the loop is being en
larged the iingers 88 and 98 moved thereby pass
through the loop and upon engagement of the
plates 96 thereof with wedge member 98 are
opened to embrace the free ends 258 and 252 of
this cut section of string. The arms are closed
10 upon disengagement of Wedge 98 with plates 96
whereby these free ends 256 and 252 are disposed
and held between the forward ends of arms 88
and 90. The movement of the lever 82 is such as
to draw these free ends through the enlarged
15 loop, as clearly shown in Figure 12 of the draw
ings, to secure this section or portion of string to
the tag 8.
,
During the final step of drawing the free ends
25|] and 252 through the loop, the arms 66 and
20 68 are again brought together under the action
of spring 12 by movement over the wedge T6 to
release their engagement with the loop whereby
the tag 8 may be discharged after the free ends
258 and 252 have been drawn through the loop
25 by the arms 88 and 98. During this final step
in the operation, the arm |48 has continued to
rotate in a counter-clockwise direction and to
draw another section or portion of string around
the pins |88 and |98, and as will be noted in
30 Figure 5 of the drawings, this section or portion
of string is being drawn into position to be re
leased by pins |88 and |98 before the completed
threading and tying of the previously cut sec~
tion or portion of string has been effected.
It will be noted that the length of string se
cured to the tags I0 is dependent upon the effec
tive length of the arm |40 about the shaft |28
which provides its axis of rotation. When it is
desired to increase the length of string being se
40 cured to the tags, the bracket |66 which is ad
justably secured by the bolts 254 and 256 to the
table top 4 may be moved outwardly away from
the axis of rotation of the arm |46 and again se
cured in this adjusted position by the bolts 254
45 and 256 which may pass through any selected
openings 258 and ‘260 provided in the table top 4.
The bracket |32 is then moved outwardly and
again secured by bolts |33 in an adjusted position
so that jaws |44 and |46 will deliver the string to
50 pins |88 and |90 of the string control means |92
when the arm |48 has been adjusted.
The arm
|40 is then adjusted to conform with the move
ment of brackets |32 and |66 and secured in its
adjusted position by the set screw |42 whereby the
55 movable jaw |46 and knife |56 will be properly
operated by rollers H2 and |14, respectively.
The tags 8, after having a piece of string se
cured thereto in the manner described, are dis~
charged from the table top 4 by discharge means,
60 generally referred to as 262, which comprises a
carriage 264 pivoted at 263 and rocked by a cam
operated shaft 265, a spring 261 being provided
to normally hold the carriage in spaced relation
The tag is successively engaged by the rotating
rollers 266 to move the tag transversely over the
table top 4 and to discharge the same in front
of the machine. The movement of the carriage
264 is only slightly greater than the thickness of
the thin cardboard tags and this movement can
take place upon operation of the cam operated
shaft 265 because of the clearance provided be
tween the teeth of gears 268 and 210.
It is to be clearly understood that the machine 10
is entirely automatic in its operation from the
step of feeding the tags to the discharging of the
tags from the machine, and that the steps of
operation above described take place simul
taneously and successively, as indicated, to per
form the completed operation.
While I have herein described and upon the
drawings shown an illustrative embodiment of the
invention, it is to be understood that the inven
tion is not limited thereto but may comprehend i
other constructions, arrangements of parts, de
tails and features without departing from the
spirit of the invention.
