Abstract

672,177. Telephone sets. BOLLE, E. A. Aug. 9, 1950 [May 22, 1950; July 17, 1950], No. 19826/50. Class 40 (iv). A lamp switch 14 is controlled by a pivoted base plate 4 which carries a table set 6. The switch lights a lamp 10 when the receiver 7 is removed and extinguishes the lamp when the receiver is replaced. The base plate, pivoted at 3, can be held by a locking button 18 to keep the lamp alight when the receiver is replaced. The switch 14 may be replaced by a press-button switch engaged by the forward edge of the base plate. A glow lamp 20 disposed in a ring 19 of transparent material may be kept permanently alight.
