Abstract
23,685. Kamm, L. Nov. 2. Incandescent lamps; supporting lamps.-In a Nernst projecting-lamp, an insulating-plug a has on one side pins b to receive the porcelain base carrying the filament or filaments, and on the other the resistance bulbs c. A removable cap and a fixed cap f are screwed on to the plug or on to a ring surrounding it. The latter cap is perforated at its end j and may also be slotted at k. The leads pass through a central hole in the end j of the cap. The lamp is secured in position on the carrying-rod i<1> within the lantern by means of lugs i and a clamp i<2>. In a smaller lamp, the filament and resistance are on the same side of the plug, which is attached to a socket and clamp engaging the rod i<1>; the resistance bulb is held by spring clamps between the pins b, which are prolonged for this purpose, and the cap f is replaced by a cylinder, which may be secured to the plug by small screws at one end, and is threaded at its other end to receive the detachable cap.
