Abstract

615,003. Photographic shutters. KODAK, Ltd. (Eastman Kodak Co.), and FUERST, C. C. Dec. 31, 1945, No. 14711/48. Divided out of 613,531 under which a'Specification was laid open to inspection under Sect. 91 of the Acts, Feb. 16, 1946. Drawings to Specification. [Class 98 (i)] In a photographic shutter which comprises several pivoted shutter blades, a master member which is mounted on a fixed pivot and a latch to hold the master member in a set position until it it is released by the shutter trigger to effect an exposure movement of the shutter blades, the master member latch is released by the shutter trigger through the intermediary of an oscillatable member, which is moved in one direction against spring action, during the shutter setting operation, and is held in such position until the trigger is operated to effect an exposure, whereupon the oscillatable member is driven in the opposite direction by the spring and a part thereof releases the master member latch. Specifica- 'tion 580,074 and co-pending Specification 613,531 are referred to, the description in the latter Specification differing from that in the present Specification only in that it refers to a movable pivot for the master member.
