DEFINITION

Classification: 172/581

(under subclass 579) Apparatus in which groups of said members are changeable from one kind of arrangement to another, the change involving more than mere vertical adjustment, horizontal angling, lateral, or longitudinal adjustment which does not change the basic character of the arrangement.

(1) Note. The different arrangement may be solely for the purpose of changing the overall width of the device whereby it may be transported through a narrow opening in a fence, along a roadway, or the like.

(2) Note. The same number of groups must appear in each arrangement under this definition. For apparatus in which a group is added or subtracted see subclass 253.
