16,471. Kamm, L. Aug. 14. Incandescent lamps for projecting - lanterns. A number of filaments 13, 14, 15 of the Nernst type are arranged crossing the axis of the apparatus in different directions, being held by pairs of sheetmetal supports 1, 4, 2, 5, 3, 6 of different heights, attached to a base a. The filaments are introduced into holes in the supports through slots, which can be then closed. Each of the supports 2, 4, 5, 6 is connected to a split socket on the underside of the base, and the support 2 is also connected to the supports 1, 3 by a plate 11. The Provisional Specification mentions the attachment of conductors directly to the filament supports.
