Abstract
Abstract A machine for piling metal sheets which comprises an overhead conveyor for advancing sheets for deposit on a lift, or the like, at a piling area, end stop and backstop mechanisms and side edge guide mechanisms, for cooperation with the end stop and backstop mechanisms, which side guide mechanisms are arranged in pairs, adjustable laterally of the path of travel of the sheets with one pair of the side guide mechanisms in a fixed position at the entrance end of the machine and another pair thereof mounted for longitudinal adjustment with the end stop mechanism. The side guide members are reciprocated as the sheets are dropped, so as to facilitate the piling of sheets delivered off center, and each of said members is suspended on a linkage system to prevent damage in the event the lift is raised sufficiently to strike the guide member, with the assemblies being strengthened and held against undue deflection by means of a special chain arrangement.
