Abstract: A pusher assembly is disclosed for a scrap metal conveyor of the type having an elongated trough in which the pusher assembly is supported for longitudinal reciprocation to advance scrap metal along the trough in the direction from one end thereof toward the other. The pusher assembly includes an elongate circular push rod carrying a plurality of scrap metal pusher elements axially spaced apart on the rod and supported thereon for reciprocation therewith and for pivotal movement about the rod axis. The pusher elements slidably engage a longitudinally extending wear plate on the bottom wall of the trough and are restrained against lateral displacement relative to the wear plate by a longitudinally extending upright guide bar thereon received in guide slots in the undersides of the pusher elements.

Abstract: A holding device for holding an open-end hollow body with a pivotal carrying handle includes a mounting member for mounting the hollow body. Disposed at one end of the mounting member is an annular support member carrying a locking member. The support member serves as an abutment to define a given position for the pivotal handle, such as not to impede access to the hollow body for the printing mechanism. The locking member is movable relative to the mounting member between an operative position of securing the handle in its given position, and an inoperative position in which the handle is free to pivot into and out of its given position.
