Definitions

  • My invention relates to apparatus for exhausting incandescent electric lamps and similar devices, and more particularly to the portion of such apparatus for sealing-E the exhaust tube of the device after the evacuation or gas-filling operations have been completed.
  • the exhausting machines which are in use comprise an intermittently rotated carrier having at the periphery thereof a plurality of holders for the l0 incandescent lamp or other device. Each of these devices is indexed from one position to another and the exhausting or gas-filling operations are gradually completed as the device completes the cycle. The last operation is the sealing-01f of 16 the exhaust tube, the melting-0d of the glass tube below the sealing-off point, and the discharge of the article.
  • Fig. 1 is a plan view of the. tipping oifi device of my invention
  • Fig. 2 is a side elevation of the turret of this device partially in section
  • Fig. 3 is a vertical section along line 3-3 of Fig. 1
  • Fig 4 is a partially disassembled view of a head of this device
  • Fig. 5 is a perspective view of the head raising and lowering cam.
  • My device operates in'conjunction with a lamp exhausting or gas-filling machine which comprises a number of heads (preferably thirty-two) which are indexed intermittently in a counterclockwise direction as indicated in Fig. 1.
  • Position D into which the lamps next pass is occupied by a head of the tipping turret.
  • the turret 20 carries four such heads mounted equidistantly thereabout (Fig. 2) and is slidably mounted on valve block 21 and about shaft 22.
  • the first operation of the turret mechanism takes place as fires from the oppositely disposed burners 23 and 24 on yoke 25 strike the preheated section of the exhaust tube.
  • the yoke is sup- 76 ported through pipe 26 which is attached to block 27 on shaft 28 which in turn is slidably mounted in arms 29 and 29 of the turret 20.
  • Pipe 26 is connected to pipe 30 protruding from the wall of the turret by flexible hose 31 which receives the gas fuel mixture entering said pipe from passages in valve block 21 and shaft 22.
  • Passage 32 is circular and connects to each of the four ports leading to the heads while passage 33 is also circular but connects to passage 34 in shaft e5 22 which is fed by pipe 35 and hose 36 from the main supply .of fuel mixture.
  • the exhausting or gas charging of the machine is completed and the exhaust tube is closed off by so thefires.
  • the head is then dropped so as to stretch the fused glass and perhaps separate the surplus portion of the exhausttube. This movement is produced by the lowering of shaft 28, the roller 37 in the end of which rests at that at stage of the operation on the end of rod 38 (Fig.
  • Said spring operates between a post 60 in the slide and another post 61 in bracket 62 which supports said slide between roller 63 on pins 64 and plates 65 and 66.
  • Bracket 62 is supported through shaft 1'7 to which it is attached.
  • the fires cut the thin string of glass which is usually present connecting the bulb and the exhaust tube and fuse the seal more nearly into shape.
  • Chute 68 is supported by rods-'70 and '71 extending from slide 58 and spring 67 is attached to rod '70. This description covers one cycle of operation which is repeated as the machine continues to operate.
  • acarrier having a plurality of heads arranged therealong and each adapted to receive one of said devices, means for moving said carrier, a turret mounted adjacent the path of travel of said carrier heads and comprising a plurality of heads and means engaging said carrier heads for causing said turret to rotate as the said heads are moved to bring a turret head into alignment with a carrier head, said turret being resiliently coupled with said rotating means thereby causing it to follow the path of travel of said carrier head until another turret head engages a carried head.
  • an apparatus for exhausting or gas-filling incandescent lamps and similar devices comprising a bulb having an exhaust tube extending therefrom, the combination of a carrier having a plurality of heads arranged therealong and each adapted to receive one of said devices, means for moving said carrier, a turret mounted adjacent to the path of travel of said carrier heads and comprising a plurality of heads each comprising means engaging the bulb portion of a device and burners positioned to heat an exhaust tube carried by said device, and means whereby said turret is caused to move in proper time relation with the movement of the carrier.
