17,433. Lambert, W. R. Aug. 29. Reflectors for electric incandescent lamps have a slotted ring 5 stamped out and sufficiently resilient to be forced over the holder and to be held there securely. A portion of the ring 5 is cut away to allow the unimpeded operation of the bayonetjoint, while the bayonet stud 12 prevents the reflector from being removed.
