DEFINITION

Classification: 24/507

Having specific surface material or irregularity on or along engaging face:

(under subclass 500) Clasp*, clip*, or support-clamp* wherein one of the gripping members includes either a specific, different substance or uneven surface formation forming the structure-to-be-secured* engaging surface of the gripping member.

(1) Note. Either a specific substance different in composition from that of its gripping member or details of the facial contour must be positively claimed for proper document classification placement herein as an original.

(2) Note. The facial contour may be either integral with, or on structure distinct from and attached to, the gripping member.

(3) Note. An engaging surface existing solely in a single plane and formed along a curved, looped, or bent, gripping member is not considered to be irregular since it is not uneven in the gripping direction.
