ABSTRACT:
A transport roller system is provided for use in photographic film treating tanks employed for developing, fixing, washing and the like, in which on each side of the rack frame plates, a central driving cluster gear is provided on a roller shaft of a central vertically disposed roller system with driven cluster gears on roller shafts on each of roller systems on each side of the central vertical roller system to provide for downward and upward movement of a film strip, with provisions including pairs of actuating drive gears on alternate central horizontal roller shafts, the pairs of actuating drive gears on the alternate shafts on the outside of each of the rack frame plates comprising a driving gear connected to its respective shaft and an idler gear each meshing with contiguous gears, the pairs of gears having larger pitch circles than the cluster gears and having pitch diameters corresponding to the center to center distance between alternating shafts of the central vertically disposed roller system, whereby a very compact driving arrangement is provided of less width than has heretofore been available, and with simple provisions for entrance and exit of the film strip at the top and turnaround of the film strip at the bottom permitting more compact roller systems than before.
