Abstract
1,151,359. Lamp - holders. EASTMAN KODAK CO. 12 May, 1966 [23 July, 1965], No. 21016/66. Heading H2E. [Also in Division G2] A photoflash socket structure for receiving a multilamp flash unit (12) (Fig. 2, not shown), having a plurality of ignitable photoflash lamps mounted on a base (12<SP>1</SP>), comprises a support plate 10 provided with an aperture 14; socket means including a sleeve 13 mounted in the aperture and provided with a central opening 15 through which the base (12<SP>1</SP>) can be inserted and a stabilizing spindle 30 part 29 of which engages an inserted base; resilient means 25-27 arranged in the socket means so as to retain an inserted base in rotatable relation to the socket means; and means coupled to the resilient means for disengaging the latter from the base to permit removal of the unit from the socket means. On insertion of a unit, one pair of contacts (17), (18)-a pair being provided for each lamp, are engaged by compressing contacts 21, 22. To release the unit, a button 40 is depressed and the unit is partially ejected by the resilient contacts 21, 22. In another embodiment (Figs. 5, 6, not shown), one contact (17) engages one of four contacts (68) on a ring (46) and the associated contact (18) engages a fixed contact (69).
