DEFINITION
Classification: 83/278
(under subclass 276) Device in which the work-feed means comprises a member which engages in an opening in the work or which positively pushes the work.
(1) Note. Impaling points or fingers which form their own recesses or openings in the work are included here.
(2) Note. Push bars and the like which directly engage and push the work are included here. The "abutment surface" engaged by such pusher may be the rear edge of the work as well as any other salient portion.
(3) Note. A feed member having a rough toothed, or corrugated surface to engage work, if opposed by another moving surface so as to clamp the work, would be classified in subclass 277, but if opposed only by a stationary work-supporting surface or work guide, or by the mere weight of the work itself, would generally be regarded as imbedded in the work or abutting it within the scope of the definition of subclass 278.
