Definitions

  • This method is especially advantageous when it is important to avoid changes in the position of the bulbs during the transfer. This is more specifically true in the manufacture of lamps of small types in which the supporting stems are suspended in the bulbs, which are placed in the trays with the necks up, while 20 they are being fed to the sealing-in machine.

  • Plate 48 also is provided with a pin 51 which rides in the-cam slot 46. Upon the forward movement of plate 31 the upper end of lever 41 moves to the right (Fig. 6) and moves the plate 45 ahead in the support 47. Due to the action of the cam solt 46 on the pin 51, the
  • the end of the lever 61 projects into the path of the pegs 59 between the disk 58 and the semi-annulus 60.
  • Said lever 61 is pivotally mounted on the bracket 62 and is connected through the slot 64 and the pin 65 to the rod 66 which moves in the supports 67 and is held in the back position by the compression spring 68 located between the forward support 67 and a collar 69 on the bar 66.

  • Said rod '18 is provided with a finger 84 (Fig. 3) which engages the indexing wheel 85 which is provided on a shaft 86 mounted in the support 87.
  • a gear 88. also provided on the shaft 86, meshes with a gear 89 provided at the end of the screw 53.
  • pegs 59 will engage the lever 61 and cause the screw 53 to turn in one direction, thereby indexing the trays 11 laterally the distance between two holes 13.
  • one of the pegs 23 of gear 22 will engage the lever 24 and, as hereinbefore explained, will cause the trays 11 to be indexed longitudinally the distance between twoholes 13.

  • the bulbs 10 are lifted vertically from the trays 11 by a transfer bar or, more specifically. a tube (Fig. 4) which is guided through .a bushing 96.
  • the said tube is reciprocated by mechanism comprising a gear segment97 which- 1 mes rack teeth. 98 provided on the tube or bar 95.
  • a counter pressure roller 99 is arranged opposite the segment 97.
  • The. tube 95 is shaped at. the top to'conform to the contour of the bulb 10 (Fig. 5) and is provided at the bottom with a hose 100 (Fig. 4) which is connected to a vacuum source (not shown). so that the bulb 10 will be held in position during its upward travel.
  • An electromagnet 101 is provided above the bushing 96 so that the tube 95. which is iii made entirely or partly of iromis magnetized.
  • the magnetized tube 95 (Fig. 5) i then attracts the lead wires 102, provided in the known manner with a nickel-iron core, and pulls them down against the neck of the bulb 10, thereby holding the supporting stem 103 with its filament 104 and. lead wires 102 in place during the lifting motion.

  • the slider 116 with the jaws 119 is arrested by a stop 123, but the slider 107 continues forward with the bar 114.
  • the conical end 124 of the bar 114 moves between the blocks 122, thereby opening the jaws 119 and allowing the bulb 10 to drop into the holding head 12.
  • the bar 114 with slider 107 is then stopped due to a springy catch 125, provided on slider 116, slipping into the groove 126 in the bar 114.
  • the slider 116 then moves back with the slider 107 due to the fact that they are coupled by thecatch 125, until said slider 116 strikes the stop 127 which occurs as the clamps 119 come into position over the lifting tube 95.
  • the slider 107 then moves back somewhat farther disengaging the catch from the groove 126, and
  • the extreme left-hand hole of the front row of the tray 11 is located over the vertical lifting bar or tube 95 (Fig. 4).
  • the bar 951 rises vertically through the hole in the tray 11, lifting the bulb 10 which is held tight to the bar by suction, and delivers said bulb to the opened jaws 119.
  • An electromagnet 101 magnetizes the bar 95 which then attracts the leads, 102 (Fig. 5) and holds the filament mount in place in the bulb.
  • the clamp Jaws 119 close around the bulb and release said bulb from the bar 95 which moves down below-the tray 11. Then the jaws 119 with the transferring mechanism move radially toward the holding head 12 of the sealing-in machine, where they are opened to allow the bulb to drop into said'holding head.
