DEFINITION

Classification: 414/792.7

Positions lowest article of stack first:

(under subclass 788.1) Apparatus wherein the initial article placed within the stack* being constructed is the article which will be located at the bottom thereof and upon which all other subsequent articles are supported as the height of the stack* is increased.

(1) Note. A stack which consist solely of imbricated (i.e., lapped) articles having their lowest portion with a common plane is excluded from this and the indented subclasses, since the height of the stack* is not increased by the addition of articles thereto.
