This invention relates to a coiling apparatus
and more particularly to an apparatus for se
lectively coiling lengths of cordage.
It is an object of the present invention to pro
vide a simple and effective apparatus for coiling
lengths of ñexible material.>
`
l
In accordance with one embodiment of the
invention,.an apparatus is provided for coiling
multi-conductor cordage in coils of lengths de
termined by the distance between points where
the conductors extend in loops through the cover
ing on the cordage, In this apparatus, an angu
a cord coil supporting table I3.- Fixed to the
stationary bearing post I0 is an annular support
member I4 having suitably attached to it a
housing base I5 on which there is in turn mounted
a housing I6.
'
The housing I6 has a motor I1 suitably
mounted therein and connected to a gear re
ducer I8 for driving a pulley I9. The pulley I9
is adapted to drive a belt 23 which in turn drives
the driving element 2| of a clutch assembly desig
nated generally by the numeral 22 (Fig-_3). The
driving element 2| is freely rotatable on a shaft
23 and may be clutched to the shaft by clutch
discs 24 surrounding the shaft 23 and seated in
to lay- a coil of cordage on the bottom ofthe 15 a nest 25 in the driving element 2| when pressure
is applied to the fdiscs 24. Pressure maybe ap
receptacle and mechanism is provided for with
drawing the bottom of the receptacle each time , plied to the discs‘24 by a sleeve 26 having a pair
of shoulders 21 and 28 formedon it forv receiving
the projectingloops of conductors pass a pre
clutch operating rollers 29 mounted upon op
determined point in the apparatus.

respectively, which are jour

bracket 4i and have fixed to their lower ends
a pair of levers 59 and 59. Formed- integrally

them are a pair of closure plates 99 and 9i which '
coo_erate to serve as the bottom of a coil re-ï
ceptacle 99 which comprises, in addition to the H
closure plates 99 and 9 i , a frusto ccnically shaped
Wall member S3 which is connected to the bearing
portion 5l of the bracket ¿l1 by web members
Sii-99. The abutting edges of the closure meme
bers 99 and 9|, as shown most clearly in Fig. 2,
have angle members 65-'95 attached to them
for cooperating with the bottom surfaces of the
'closure members to support soit rubber gaskets
(i6-«99.
The housing` I6 is irregularly shaped, as shown _
in Fig. 3, and has a gear case 15 mounted on it
which serves to enclose the driving gears for the
mechanism which feeds coils into the coil recep
tacle 92. These driving gears comprise a gear
16 (Figs. 3 and 5) fixed to the shaft 23 and mesh-ì f;
ing with a pinion 11 mounted upon a stud shaft
‘i8 suitably journalled in the housing i6 and hav
ing keyed thereto a pinion 'i9 and a worm gear
S9. The pinion 19 meshes with and drives a
gear 8| fixed to a Istud shaft 92 and carrying a
spur gear 33 which in turn meshes with a spur
gear 84 on a stud shaft 85. The stud shafts 82
and 85 have keyed to them a pair of feed rollers
85 and 91, respectively, having soft rubber tires
ûßand 99, respectively, for engaging and feeding
cordage 99.
The shafts 82 and 85 are mounted
in bearing blocks 9| and 92 suitably attached to
the'hou‘sing I5 and gear case 15 in position to
support the drive rollers 89 and 81, in .position
to feed cordage 99. The cordage 99 fed by the
rollers 89 and 91 vis withdrawn from a supply (not
shown) and passes over 'a guide pulley 99 (Figs.
1 and 2) journalled for free rotation on a bracket
94. The bracket 94, in addition to supporting the
pulley 93, also supports a trigger mechanism des- .
ignated by the numeral 95 and so positions the
pulley 93 that 'cordage 99 fed over the pulley will
be directed into a funnel-shaped guide member
96 having a pair of wings .9L-91 as shown in Fig.
1, for guarding the upper surface of the feed roll- l.
ers S9 and 81. The guide member 99 is cut away
as shown at 98 (Fig. 2) to permit the entry there
in of a trigger 99. The left end (Fig. 2) of the
trigger 99 is bifurcated to receive the cordage
99 between its tines and is pivoted on a pivot pin
|99 and urged to rock clockwise to the position
shown in Fig. 2 by a spring pressed plunger I9!
seated in a socket |92 formed in the bracket 99
and urged to the left (Fig. 2) by a compression
locked Vin its operated position by an armature
||9 of a relay III, a camming projection II2 on
the armature _|I9 serving to hold the contact
member |91 in its operated position until the relay
||| is energized. The contact member |91 upon
engaging the contact I 99 will complete a cir
cuit from a current source I i3 to energize the
solenoid coils 49 and 42, and will hold the solenoid
coils energized until the relay I |I is operated un- der control of a switch I I4.
The worm gear 89 on the shaft 18 meshes
with a worm gear |29 which is mounted upon a
nozzle member I2! by means of a locking ring
|22. The nozzle member I2I is freely rotatable
in bearings |23 which are held in the housing I9
by a retainer ring |24 and which cooperate with
an upper bearing member |25 to position the
nozzle member I2| inthe path of Ycordage 99 fed
downwardly by the feed rollers 89 and 87|. Oper
ation of the feed rollers 99 and 81 and the noz
zle member I2| will be initiated each time a switch
actuator |29 mounted upon the cord coil 'sup-V
porting table I3 passes the switch ||4 due to the
engagement of the switch kactuator“ |26 with a
plunger |21 of the switch I Ill.
In the operation of the apparatus cordage 99
may be withdrawn from a suitable supply (not
shown) and directed over the guide pulley 93
and thence down between the feed rollers 86 and
81 and through the nozzle member I2I to prepare
the apparatus for operation. As soon as current
is supplied to the motor l1 the feed rollers 86
and 81„wi11 feed the cordage downwardly into
the nozzle member I2I due to the fact that with
the circuit in the condition shown in Fig. 6 the
solenoid coil 49 is de-energized. The cordage
drawn over the pulley 93 by the feed rollers 85
and 81 will continue to feed through the nozzle
member |2| which will be rotated through the
gearing including the worm gears 89 and |29 at
all times that the feed rollers 99 and 81 are driven.
Since the motor I1 operates continuously,- the
feeding of cordage will continue until solenoid 42
is energized to release the clutch discs 24 and-to
permit spring 38 to apply pressure to the brake
discs 93. The shaft 23 will therefore continue
to be driven, and, through the gearing in the gear
case 15 will continue to drive the feed rollers 86
and 81 until looped out conductors |95 of 'the
cordage 99 engages the trigger 99 thus to operate
switch |94. When switch |94 is operated to en
gage contact member |91 with contact |98 it will
be locked in its operated position by the armaà
ture ||9 and due to the completion of a circuit
through the contacts of switch |94 the solenoid
lcoils 49 and 42 will be energized. Energization
of the coil L39 will render the clutch discs 24 in
effective and will render the brake discs 33 eifec
70 rtive thus to 'stop rotation of the shaft 23 and 'stop
spring |93. Movement of the trigger 99 clock
wise beyond the position in Fig. 2 is blocked by a
surface of the housing of a switch |94.
As is shown most clearly in Fig. l, the cordage
99 has conductors |95---|95 thrown out through
its covering at intervals and when a group of 75

ping of the feeding of cordage, solenoid 42 will
be operated to attract its core member 43 and
through the link 44 to rock the bell crank lever

45 counter-clockwise (Fig. 1). When the'lever 45
is rocked counter-clockwise the plunger 48 will
beL moved to the left (Figs. 1 and 4) and through
the operation of the double sided rack 49 will ro

.to swing the closure plates 60 and 6| out from
under the wall member 63, that is, from the po
sition shown in full lines ìnFig. 2 to the position
shown in dot and dash’ lines, thus to drop the
coil of cordage `90 which had been in >thercoil
receptacle 62 into the cord coil supporting table

where the closure plates are open and the feed
rollers 86 and 81 and nozzle member I2I are in
operative until the table >I?. carries a switch. ac- _

will retract it to the position shown in Fig. 6 and
the circuit to the solenoid coils 40 and 42 Willbe
broken, thus to reinitiate a feeding cycle for the
