(under subclass 489) Clasp*, clip*, or support-clamp* wherein the swinging gripping member is shifted between positions by an operator* including two rigid* arms, the first arm being pivotally attached at opposite ends to both the second arm and to the separate, swinging gripping member while the second arm is additionally pivotally attached to the other gripping member or to structure linking it thereto, the operator* transmitting a force of varying intensity to the separate, swinging gripping member as pressure is applied by moving the common connection of the two arms in a direction transverse to the longitudinal axis of either of the arms.
(1) Note. The operator* must not directly contact the structure-to-be-secured* to be proper for this subclass.
