Abstract: An assembly of a hand rail, a shoe rail, a plurality of parallel balusters joined to the hand rail and the shoe rail through a pair of intermediate plastic webs attached both to the baluster and the adjacent rail so that the rails and balusters can be moved to any angular disposition keeping the balusters parallel to each other and the hand rail and shoe rail parallel to each other. The plastic webs include spaced tabs which are attached to each baluster end and provide total collapsibility to the rail section which is universal in use to any rake of the stair.

Abstract: An angularly orientated print head is displaced by a reciprocating power actuator from contact with a wet inking surface along a fixed travel path having acceleration and deceleration portion. A shock absorbing guide roller stabilizes the orientation of the print head as it approaches its marking position along the deceleration portion of the travel path. A drive mechanism between the actuator and the print head renders movement thereof to and from the marking position continuous for imprinting continuously moving target material.
