Abstract
487,340. Photographic shutters. DECKEL, F., (trading as DECKEL, PRAZISIONSMECHANIK UND MASCHINENBAU, F.). Dec. 18, 1936, No. 34866. Convention date, Dec. 21, 1935. [Class 98 (i)] A locking member preventing actuation of the release member unless the shutter mechanism has been set or the setting member moved to the " Bulb " or " Time " position, is mounted inside the shutter casing. The master member 1 has a shallow recess opposite the detent 2 which allows a spring 3 to rock the detent arm 4 into the path of a nose 5 on the trigger 6. The timing lever 8 has a finger 10 resting on the setting ring 11 which has two recesses 12, 13 corresponding to the "B" and "T" settings. When the master member 1 is rotated so that the detent 2 engages notches 15, the arm 3 of the detent 2 is swung out of the path of the nose 4. Similarly when the ring is set for " B " or " T ", the end of lever 8 falls in one of the recesses 12, 13 and a finger 9 on the lever 8 moves the detent 2 out of the path of the nose 4.
