Auxiliary pile board assembly for printing presses

In an auxiliary pile board assembly for temporary occupation of spaced supports provided at the delivery end of a sheet-fed printing press, the combination comprising a pair of longitudinal rails of substantially equal length spaced parallel to one another for registering with the spaced supports, first and second cross rails of equal length, the first cross rail extending perpendicularly between corresponding ends of the longitudinal rails and secured to the latter, the second cross rail extending between the longitudinal rails parallel to the first cross rail, an auxiliary pile board of limited dimension interposed between and supported upon the cross rails, the longitudinal rails having longitudinally extending way surfaces thereon, the ends of the second cross rail being slidable on the way surfaces for purposes of lateral adjustment, the ends of the second cross rail having respective clamping members for applying pressure against the way surfaces, and means for tightening such members against the way surfaces for immobilizing the second cross rail in adjusted position with respect to the first cross rail for individual accommodation of a number of different pile boards of limited dimension proportioned to the size of the sheets being delivered by the press.
