DEFINITION

Classification: 254/105

STEP-BY-STEP TRAVELING BAR:

(under the class definition) Pushing and pulling implement not classifiable in the preceding subclasses comprising a bar adapted to engage a load or a support and means for causing it to travel in a step-by-step movement relative to other elements or the implement.

(1) Note. The "bar" may act as a lever and may itself be the power-applying or increasing lever, provided it has a bodily travel relative to other parts of the implement. It should be noted that the "travel" of the bar is relative. Hence, if the bar acts against a fixed support, the actual travel relative to such support will be performed by the other load-engaging elements.

(2) Note. For classification purposes, this subclass is considered superior to subclass 93 above.
