Arrangement for feeding the bulbs of electric vacuum devices

Claim 1

An arrangement for feeding bulbs of electric vacuum devices, comprising a conveyor for loading bulbs into an automatic exhausting and sealing-off machine, a mechanism for feeding said bulbs onto said conveyor, said mechanism being a set of successive first through last sections in the feed direction for said bulbs, each said section including a train of a number of consecutively arranged rotatable shafts each having a number of disks mounted thereon, rotation of which is adapted to set said bulbs into progressive motion, the number of the shafts in at least some of said successive sections being less than that in a preceding section, the disks on each following shaft in each respective section being of a diameter larger than the disks on the preceding shaft in said section, disks of different diameters being mounted on a last shaft in all of said sections and on all of the shafts in the last section in the feed direction of said bulbs providing lateral orientation of the bulbs so as to align the latter in the feed direction thereof, the increase in diameter of the disks in the feed direction of the bulbs imparting an increased linear feed velocity to the latter for conveying the bulbs into the machine.
