DEFINITION

Classification: 414/797.4

Removes lowest article first from stack:

(under subclass 795.4) Apparatus which reduces the height of the stack* by initially taking the lowermost article from the remaining portion of the stack*.

(1) Note. A stack* which consist solely of imbricated (i.e., lapped) articles having their lowest portion within a common plane is excluded from this and the indented subclasses, since the height of the stack* is not reduced by the removal of an article therefrom.
