ABSTRACT:
A curved guide for paternoster-type document carriers of the type wherein at least one carrier is connected by a support arm rotatably articulated on each front side to an endlessly moving chain, said carrier being conducted by means of a bent lever attached to the front side of each carrier in an inverted V-shaped position with the aid of guide rollers provided at the lever ends and running in slotted guideways which intersect at the two deflection points, wherein the improvement comprises a pair of pivotally mounted and automatically settable or reversible point levers at the guideway intersection. The point levers close the respective entrance and exit of one slotted guideway from the other slotted guideway with the sides of the point levers forming a continuous slotted guideway bridging the entrance and exit of the other slotted guideway. The point levers are coupled by an endless chain. A rubber-metal buffer cushion adjacent the obtusely converging sidewalls of the slotted guideways reduces noise and insures an elastic impact of the point levers against the buffer cushion.
