(Cl. 242-82) 1 r 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.

The housing 4| processing machine which maybe of'. the type disclosed in the copending application of R. T. 50 has a solenoid coil 42 mounted in it >adapted to actuate a core- member 43. The core-member v43 Adams and J. A. Wagner, Serial No'.v 572,414 lever 45 mounted upon a- pivot pin 46. The pivotpin 46v is carried by a bracket 41 in which there the processing machine, and having ñxed to it 55 is slidably mounted a plunger 48 (Fig. 4) . Formed comprises a driving gear |2, adapted to be driven in timed relation to the various operations of 3 2,407,353 on the left end of the plunger 99, as shown most clearly in Fig. s, is a double sided rack #le which these extending conductors engage the trigger 99 they will rock the trigger counter-clockwise is urged to the right (Figs. 1 and 4) by a corn against the action of the spring |93 thus to actu pression spring 59 seated against a shoulder El The compression ate the switch |94. As shown most clearly in Fig. 6 the switch |94 has an actuator plunger |99, spring 99 surrounds the shank of the plunger ¿i9 which upon movement of the trigger 99 in a formed in the bracket Lil. and, in addition to bearing against 'shoulderr 9i, counter-clockwise direction (Figd 2) will shift a ‘bears against a collar ‘52 on the plunger thus to urge the plunger 98 into engagement with the vertically extending arm of the bell crank lever ¿59. Meshing with the rack 99 are a pair of gears 53 and 59 suitably fixed to the upper ends or stud shafts t9 and respectively, which are jour nalled for rotation in a bearing portion 5l of the` bracket 4i and have fixed to their lower ends a pair of levers 59 and 59. Formed- integrally with the levers 59 and 59 or suitably attached to contact member |91 into engagement with a con tact |98. The Contact member B91 is normally urged to an inoperative position (opposite to that shown in Fig. 6) by a spring I 99 and will be 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 the operation of the feed rollers 88 and 91 and nozzle member 2 |-. Simultaneously with the stop 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 2,407,353 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 tatethe shafts 55 and 56 in opposite directions .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 I3. -The apparatus will remain in the condition 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- _ tuator |26 into engagement with the plunger I21 whereupon switch IIA will be operated to supply current to relay III and thus. attract armature IIO and release contact member |01. Whenthe .contact member _|01 is released, the spring |09 . 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 cordage. When the ysolenoid coil 40 is de-ener gized the shaft 36 will be swung to its clockwise position (Fig. 3)> by theY contractile spring 38, thus supply, means associated with the coiling means .for receiving .the coils, means under control of the' cordagefor causing the receiving means to Adischarge acoil onto the processing machine, and -means :under control of the processing machine for restoring the receiving means to condition to .receive a coil. 1. . 5.
