Abstract
290,610. General Electric Co., Ltd., (Assignees of Patent-Treuhand-Ges. f³r Elektrische Gl³hlampen). May 17, 1927, [Convention date]. Filaments, supports for.-In mounting spiral filaments on support wires a filament is inserted in a jig and a lamp pedestal is positioned with respect to the jig, and the filament is then moved longitudinally to thread it through the eyes of the support wires. The jig shown in Figs. 1 and 2 comprises a straight section 2 and an arcuate section 3 having radial notches 8 into which the ends of the support wires 9 projecting from the lamp mount 10 are inserted, with their eyes in line with a groove 7. A filament is passed down the sloping top 4 of the jig section 2 into a straight groove 5, and this is covered by lowering a block 6 on to the surface 4. The filament is then moved longitudinally from the groove 5 by means of a rod 22 and passes through the groove 7 and is thus threaded into the eyes of the support wires. During this operation the groove 7 is covered by a plate 14 carried by a pivoted arm 13, the cover being slotted at 15 to allow the wires to bepassed vertically into the notches 8. The ends of the filament are attached to the hooks 18 of the leading-in wires by pinching-jaws 20. In the modification shown in Fig. 6, the filaments are threaded into the eyes by compressed air, which is supplied to a channel 24 parallel with the grooves 5, 7 and is directed into these by inclined passages 28. A rotating disc valve 29 having a number of ports 30 admits the air in short puffs. A modification is described wherein the filaments are drawn by suction into the eyes of the wires. The apparatus may occupy one of the stations around a. rotating hook-inserting machine, the next station to it being occupied by an annular clamp which pinches all the eyes more tightly around the filaments.
