Abstract

1387956 Electro-photographic development SPERRY RAND CORP 21 May 1973 [3 Nov 1972] 24089/73 Heading G2H Apparatus for replenishing the developer in an electro-photographic copying machine comprises: a toner hopper 10 having a slot-shaped dispensing opening 44 and pivotable arms 40 that are oscillated back and forth to push toner under a deflector 55 towards the opening 44 during each cycle; the arms 40, which are linked together by a member 46, being driven by a rotating cam 38 via a cam follower arm 30 the bottom end of which extends laterally to engage a roller 52 on a sideways extending arm 50 of the first pivotable arm 40. The limit of travel of the arms 40, and hence the quantity of toner dispensed in each cycle, is determined by the cam 38 in one direction and by a manually adjustable stop 62a in the other direction.
