Abstract: 377,401. Electric lamps with cut-out arrangements. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and PEARCE, A. G., of General Electric Co., Wembley, Middlesex. July 2, 1931, No. 19081. [Class 39 (ii).] In electric incandescent lamps of the type provided with a gas pressure sensitive device which is adapted, upon the breakage of the bulb and the consequent variation of the gas pressure to effect the interruption of the supply of current to the filament, the device is arranged within the bulb so that when the gas pressure within the bulb changes suddenly the pressure on one part of the device varies more rapidly than that on another part. The device comprises a cylinder 10 which is closed at its lower end and supported on the foot tube 2 of the bulb by a metal strip 11. A piston 9 within the cylinder is pressed towards the open end of the latter by a helical spring 12, and normally makes contact with the lower end of a leading-in wire 8 which is bent downwardly within the bulb, the other leading-in wire 7 being connected to one end of the filament 5. A filament support 13 is connected between the other end of the filament and the metal strip 11. When the bulb breaks, the sudden increase of pressure on the upper side of the piston forces the latter downwardly and breaks the filament circuit, the piston being then held downwardly in this position by a detent consisting of a V-shaped spring 15 which is spot-welded to the side of the cylinder and disposed so that one of its limbs projects through a slit in the cylinder wall and bears against the wall of the piston when the latter is in its upper position.
