Definitions

  • Fig. 3 is a top plan of Fig. 2, and a Fig. 4 shows, to an enlarged scale, a detail of the apparatus illustrated in Fig. 2.
  • a pile of cards to be fed to a machine is placed in a magazine 1 supported by a frame plate 2.
  • a throat 3 which is formed by a throat knife 4 secured to the front of the magazine by screws 5, Fig. 2, in a manner such as to permit the throat knife to be adjusted in a vertical direction, as viewed inv Fig. 2, :so as to permit adjustment of the knife relative to a throat pad 6 thereby to define a throat 3 which'will permit the passage of one card only at-a time.
  • the throat pad 6 comprises a flat plate secured in :any suitable manner, as for example by screws, to a carriage 7 which is disposed beneath the magazine to be reciprocable relative thereto towards, away from, fand between, see Figs. 2 and 3, feed rollers 8, 9 which are rotated from the main shaft, not shown, of the machine and which receive those leading end portions of cards ifed from the magazine 1, and which extend beyond the sides of the carriage 7, and feed the cards into the machine at a very high linear speed.
  • the carriage 7 is guided by freely rotatable rollers engaging opposite edges 10 and 11 of the carriage and also the under side of the carriage.
  • the rollers engaging .the under side of the carriage comprise a pair of ball races 12, one of which is shown in Fig. 2, and a third tained in engagement with rollers 12, 13 by a spring 14, Fig. 2.
  • the side 10 of the carriage is engaged by a pair of ball races 15 spaced apart along the path of the carriage, each'roller 15 being supported by a bellcrank 16, Fig. 3, pivoted at 17 to the plate 2; Springs 18 urge the rollers 15- about the pivots 17 into engagement with the side 10 V of the carriage.
  • the side '11 of the carriage is engaged by ball races 19 also spaced apart along the path of the carriage and mounted on-angularly adjustable eccentri'cally mounted pillars 20, Fig. 1, supported by the plate 2. The purpose of the eccentric mounting for the rollers 19 will be described-below.
  • Reciprocation of the catl'iagefi is effected by a cam 21 rotatable from the -'main drive, not shown, of the machine.
  • the cam 21, as;shown i n Fig. 2, is rotatable in a horizontal plane and co-operates with a follower roller 22 mounted on the carriage 7 thus imparting movement directly to the carriage.
  • the roller 22 is maintained in engagement with cam 21 by two springs 23, one of which is shown in Fig. 2.
  • the opposite ends of the plates 24, 25 are supported in substantially abutting relation by a ramp 27 mounted on the carriage 7 for movement relative thereto, thereby to determine the distance by which an edge 28 of the plate 25 projects above the edge 29f, Fig.14, of the plate 24.
  • the 'edge portion 28 which projects above the edge 29 constitutes a picker knife which engages the rear edge of the bottom card of a pile contained in the magazine so as to effect the delivery of the card through the throat 3 to the feed rollers 8, 9.
  • the distance by which the edge 28 projects above the edge 29 is of the order of .005 inch.
  • the extent of projection of the edge 28 above the edge 29 can be adjusted by the ramp 27 since, as can be seen clearly from Fig. 4 the ramp is secured relative to the sloping faces, one of which is engaged by the resilient plate 24 and the other by the resilient plate 25. Accordingly, by movement of the ramp 27, to the right or to the left as viewed in Fig.
  • edge portion 28 should be arranged so as squarely to engage the rear edge of a card in the magazine and by effecting angular movement of the eccentric pillars 20 supporting the rollers 19,
  • the facility for adjustment of thepiclger device is also an improvement over the kinds of picker device usually employed in card-feeding apparatus as in theusually employed forms of card feeding apparatus, the knife is wholly fixed relative to the carriage .thereforaand no adjustment thereof todetermine the height of the cardengaging face'thereof is possible.
  • Iclaimn 1 V a ,7 C feeding pp a s r p, 'nsv in ombi a ion a magazine including athroat through which cardscan be fed one at a time, feed rollers co-operating to effect ment to the carriage in a manner such thatilinitial engagement of the picker device with acard is effected at a low velocity and movement of the picker'device is thereafter accelerated to deliver the cardto the, feed rollers at a linear speed substantially equal to that of the feed rollers 1 ,7
  • Card feedingapparatus aceording tociaing l wherein the thorat is'jformed by a throatfknifeicarried by the front wall of the magazine, and a throat pad spaced from the knife and carried by the end of the carriage remote from the end thereof which is engaged by said earn.
  • Card feedingapparatus according to claim l including rollers supported to be freely rotatable ina horizontal plane and to engage the opposite sides of the carriage during reciprocation thereof by the cam.
  • Card feeding apparatus including rollers supported to be freely rotatable in a vertical plane and to engage the underside of the carriage.
