Abstract
267,442. Friedeberg, H., (trading as Kr³ger & Friedeberg, E. A.). NOV. 30, 1926. Addition to 262,424. Holders.-In holders for tubular electric lamps as described in the parent Specification, wherein the contacts remain disconnected from the live supply wires underneath the holder until the guards have been placed over the bulb caps, the guard at one end of each bulb is permanently connected to the holder and that at the other end is formed as a plug in the manner described. Several modifications of the electrical connections between the divided plug sockets and the supply leads are also described. The exposed end of a guard or protective cap E, Fig. 2, may be closed by a spring flap P pivoted at P<1> and catching into a recess E<1>. To provide for bulbs having central contacts in the end caps, contacts Q, Fig. 20, are arranged both in the fixed cap E<2> as shown on the left of the Figure, and in the detachable cap E as shown on the right, in which case the contact is extended downwards to act as a plug to engage the contacts C arranged on a plate T housed in a recess beneath the holder. Two central contacts Q may be arranged as shown in Fig. 15 in a double holder for connecting two bulbs. To prevent the accumulation of metal particles, produced by repeated insertion of the plugs, across the members C, D, Fig. 5, of the divided sockets the holes H in the holder leading to the socket are widened at the base as shown.
