Abstract

764,412. Photographic film processing machines. KJELLBERG, S. R., and NORDH, K. E. 1. Jan. 12, 1955 [Jan. 12, 1954], No. 964/55. Class 98(2) A machine in which films in holders are carried edgewise through successive developing, fixing and washing chambers by an endless conveyer is characterized by a film loading section and feed device comprising a pair of guides placed transversely to the carrier and arranged to transfer one film holder to the conveyer each time the latter has travelled a distance corresponding to the length of the holder. In Figs. 1, 2 the holders 8 with films 9 slide down sloping guides 12 to be received by a belt 5 constituting the conveyer and conveyed fast spray pipes 10 for the several processing liquids in chambers A, B, C and D, the feed device (Fig. 3, not shown) allowing each holder to pass to the belt only when the prior holder has travelled out of the way. In a modified form of the loading section and feed device (Fig. 4, not shown) a pair of serrated bars replace the sloping guides 12 and a second pair of serrated bars outside the first pair are caused to perform a planetary motion to move the film holders one step forward towards the belt each time a projecting part on the latter actuates a switch operating a magnetic clutch of a driving mechanism for the movable serrated bars.
