Abstract

888,254. Indicating-apparatus. AGFA A.G. April 2, 1958 [April 6, 1957], No. 10680/58. Class 106 (4). [Also in Group XX] In the photo-elec- tric exposure meter described in Specification 833,954, the transmission mechanism between an operating disc 14 and needle deflection indicator 11 comprises a lever 17 pivoted on a pin 18 fixed to a plate 6. A cam surface 21 formed on the disc 14 engages a pin 19 carried by the lever 17 which also carries a pin 20 working in a slot 23 of a plate 9 rigidly secured to the indicator 11. The pivot of the plate 9 is carried by the plate 6 and is offset from the pivot of the disc 14, but may be formed in one piece therewith. The pin 10 connecting the plate 9 and indicator 11 works in a slot in the plate 6 and a spring 24 secured to the plate 9 ensures working engagement between the pin 19 and cam surface 21.
