Definitions

  • My invention relates to devices'for feeding wires, rods, tubes or similar articles and more particularly to the feeding of lengths of such articles one at a time from a pile thereof.
  • ' invention is particularly useful for feeding coiled filaments for incandescent lamps.
  • Such filaments are usually quite small and quite-flexible so that they have a tendency to pack together in a pile and become very dimcult to separate.
  • the filaments are disposed in a pile parallel to one another and are handled as carefully as possible. Even though much care is expended the filaments have a tendency to become entwined and tangled together so that if 5 one .is lifted, others often hang thereto.
  • the principal object of my invention is to provide a device for effectively picking up coiled filaments oneat a time from a pile thereof.
  • I provide jaws for entering into a pile of filaments and gripping one of said filaments, and means for carrying said jaws to and 5 from said pile.
  • Another object of my invention is to provide means for increasing the probability of said jaws picking up a filament from the pile. In order to do this I prefer to provide one jaw with a plurality of notches or'pockets therein,
  • This feature provides continuous feeding at all times and eliminates filament jams in the pile.
  • Another object of my invention is 0 to provide means for feeding a sufficient number of filaments for a long period of operation and to providea number of pilesof said filaments which are automatically brought to the feeding 45 position successively.
  • Fig. 1 is a perspective view of my device for feeding incandescent lamp filaments with a portion thereof broken away and 6 carried to one side;
  • Fig. 2 is a perspective view; of the turret therefor and its indexing mechanism;
  • Fig. 3 is a vertical elevation partially in section ofthe device at the feeding position showing the relative location of the various parts; 10
  • Fig. 4 is a vertical section on an enlarged scale through the filament bucket adjacent the pick-up jaws which are shown at the position of their maximum penetration therein;
  • Fig. 5 is a perspective exploded view of the pick-up jaw asseml5 bly;
  • Fig. 6 is a plan view of a'turret bucket or container for filaments at feeding position and parts associated therewith;
  • Fig. -'7 is a perspective view of a filament bucket modification; and Fig.
  • V is a side elevation of the ends of modified fila-v so ment pick-up jaws.
  • the embodiment of my invention shown in Figs. 1 and 2 consists of a turret lll.ha,ving buckets or containers ll distributed about the perlphery thereof inwhich the coiled filaments I2 are piled.
  • the filaments lie parallel to each other and tangentially to the turret on the bottoms of the buckets which slope slightly downward toward the middle.
  • the insides of the buckets are highly polished so as to cause the filaments to slide down by their own weight into a pile at the middle of the bottom.
  • the filaments are fed from the exposed bucket into which the jaws 2
  • the end of jaw 22 is provided with a plurality of notchesor pockets 26 each of which may receive a portion of a filament.
  • said notches 01' pockets preferably'comprising partially circular portions of substantially the same diameter 2
  • and 23 are located below washers 23 and 29 which, through-bolt 30 and nut 3
  • , 23, is mounted between the cone points of screws 33 (only one shown) in head 25 and is held in the open 'position by wedge 35 which prevents spring 36, located between the finger 32 and screw 31 in the head, from pulling it out of position.
  • the wedge 35 is supported on screws 38 which are mounted in holes 38' in opposite sides of the head, and during the open position said wedge is located against the said finger adjacent shoulder 39.
  • Spring 48 extending between the wedge and a post 4
  • Lever 56 is turned about pin 51 in bracket 48 by rod 55 which is connected thereto by yoke 58.
  • Spring 58 (Fig. 1) carries the rod back into position after the operation has been completed.
  • Lever 42 operates about a pin 68in bracket 48 and is actuated from the face of a cam 6
  • the lever 68 turns about the shaft 69 which is held in a bracket 10 extending between supporting posts 20 and is turned by lever H through spring 12 which extends between arm 13 on lever 68, and a post lever 1
  • Lever is turned by track 14 in cam 6
  • 23 which then cannot move any farther, so that only one filament will be picked up at a time.
  • the said notches 26 are also preferably spaced apart a distance less than the diameter of the filaments 5 to provide greater assurance that the uppermost filaments in the pile will be engaged in the said notch.
  • the said jaws, with a filament gripped therebetween at its mid-point, are now moved upward into the position shown in Fig. 3, thus '1 pulling the mid-portion of said filament through slits l8, 18 (Fig. 6) formed between the front edge of a plate 16 and fingers 83, 84 mounted at the said front edge of plate I6.
  • the needles H are then caused to move apart laterally to engage the outer portions of the gripped filament and pull them through the slits 18,18 which are 5 just large enough to allow one filament to pass through, thus combing said gripped filament free from other filaments below said slits which may have adhered thereto. Any adhering filaments then drop back into the bucket
  • the needles 50 11 are operated by further movement of lever 85, the flange of which comes in contact with rollers 95 on pins 96 in lugs 91 of arms 83 which swing against the resistance of spring 81' located be tween spring posts in both of the arms 83 and 55 whichcarry the arms from a position set by stop screw 88 contacting with arm 98 of bracket 48.
  • Plate 16 is mounted on cross bar I00 (Fig.
  • each finger 93 and 84 is welded to an end of a spring plate I 84, the other end of which is attached to block I05 by screws I06 and I0! (Fig. 6) and which can be moved with respect to 65 the plate 16 to adjust the size of the slots I8, 19 by adjusting screw I08.
  • Block I05 is attached to guide plate I08 which is fixedly mounted on bracket
  • Slide I I2 is pulled back to deposit the filament on slide .4 (which corresponds to gate 4 of the mounting machine disclosed in the Flaws patent hereinbefore referred to). As the slide I I2 is drawn back the filament is lowered on the fingers IIS of plate I09 and fingers II 6 of slide 2 which mesh together and which deposit said filament on slide 4M in a straight and untwisted condition 'at the proper location.
  • Means are provided forindexlng the turret I to present successive buckets It at the feeding position, although such means may be disconnected if desired.
  • the indexing action jars the filaments in the containers or buckets ii down into position so as to settle the loose ones in place.
  • This means is shown in Figs. 1 and 2 and operates from lever 69 through universal joint I26 and rod I21.
  • the rod is connected to arm I28 through universal joint I29 which turns freely about column Is and engages, through pawl I30, av ratchet IIZI on a vertical sleeve portion I32 of the turret It.
  • the pawl I30 turns about pin I33 and is kept against the ratchet by spring I34 which extends between I a post in the pawl and another post I 35 In arm I28. when it is desired to have the turret remain in one position the pawl is shifted so that protuberance I36 thereon rests against post I35.
  • the ratchet is coupled to the turret by pin I37 and is provided with anotherset of teeth I38 which are engaged by a roller I39 to properly position the turret.
  • the said roller I39 is mounted on pin I40 in a lever I4I which is mounted on pin I42 in bracket I43 and which is drawn against the ratchet by a spring I44.
  • Bracket I43 is fixedly attached to column I8 and supports post I45 to which spring I44 is attached as well as a brake which prevents the turret from over running.
  • the brake consists of band I46 which is fastened to post I45, is wrapped about a smooth part of the ratchet, and is at tached to rod I 41 passing through said post I45.
  • Tension isapplled to the band by spring I48 located about said rod between the post and nuts I 49 threaded on said rod. Increased tension in the brake band causes the roller I39 to snap into position more -abruptly,- thus jarring the turret more to cause the filaments to settlebetter.
  • the parti'cularbuckets and jafws described may be supplanted by others shown in Figs. 7 and 8" which are particularly suitable for feeding-larger filaments.
  • the bucket I50 differs from the end.
  • the spring wires are provided as a "cushifications may of course be made, such as the l means for withdrawing said jaws from said pile bucket II in that one half of the bottom th of has a larger opening I5I therein and the other half has a smaller opening I52 and two tongues I53 and I54 extending along the plane of said half into the opening ISI in the other half.
  • the 5 filament I2 lies as before across these openings, but is supported in this instance by spring wires I55 and I56 which are fastened to the back end' of the bucket and fit loosely in holes in the front 10 ion" bottom, to support the filaments .
  • larger opening I5I whichvis used to prevent the larger filaments from being distorted, which might happen with a small opening such as that in buckets II.
