ABSTRACT:
The invention relates to an auxiliary pile board assembly for use in the temporary support of sheets at the delivery end of a sheet fed printing press and on which sheets are deposited during replacement of the main pile board. The assembly includes a pair of longitudinal rails of equal length spaced parallel to one another with first and second cross rails spanning the space between them. The first cross rail extends perpendicularly between corresponding ends of the longitudinal rails while the second cross rail extends between the longitudinal rails and is adjustably slidable with respect thereto. An auxiliary pile board of limited dimension is interposed between, and supported upon, the cross rails. Manually operated clamps are interposed between the second cross rail and the respective longitudinal rails for clamping the second cross rail in an adjusted position, thereby to permit the assembly to accommodate a number of different pile boards of limited size, proportioned to the size of the sheets being delivered by the press. In the preferred form of the invention the clamping means is in the form of a wedge block which is thrown by a toggle linkage in and out of engagement with a wedging surface.
