DEFINITION

Classification: 226/62

(under subclass 52) Device provided with either (1) only one prong, or (2) a plurality of prongs, all spaced longitudinally*, all mounted in fixed relationship with, or integral with, each other, and all acting as a single group; the prong of (1) or the prongs of (2) as a single group being given a compound motion involving (a) movement into contact with a variation in the material, (b) rectilinear or arcuate movement longitudinally* of the material while in contact therewith to move said material, (c) movement away from contact with the variation and (d) longitudinal movement in a reverse direction while out of engagement, back to a starting position from which the movements are repeated.

(1) Note. Patents in this and indented subclasses are distinguished from patents in such subclasses 74+ and 76+ by the nature of the movement imparted to the prong(s). The

patents placed in this and indented subclasses disclose a prong which is substantially constantly oriented with respect to the perforated material; that is, a free end of the prong always points toward the material. For patents disclosing prongs constantly oriented with respect to the material but which are not fixed with respect to each other as required by (2) of the definition of this subclass (62), see subclasses 75 and 81.

(2) Note. The patents placed in subclasses 74+ disclose a prong mounted on an endless belt, chain or the like traveling about two spaced, parallel, rotated shafts or driving sprockets. In some disclosures (of subclasses 74+) the prong may be relatively fixed to the belt to rotate, during one orbit of a prong, once about an axis through the prong and parallel to the shafts. In other disclosures the prong may be mounted on two chains such that it is oriented to always point towards the material, but no confusion should exist since the prong is mounted on an endless belt or chain.

(3) Note. The patents placed in subclasses 76+ disclose a rotated wheel or drum having prongs radially mounted thereon, such devices being so different in structure and operation as to be readily distinguishable from a claw. However, attention is specifically called to certain patents placed in subclass 81 (indented under subclass 80) in which a rotating disc is provided with a plurality of pins rotating oppositely with respect to the disc in a one-to-one ratio, whereby the prongs point always toward the material during feed thereof.
