DEFINITION

Classification: 400/285.3

Tab stops grouped in stepped fashion:

(under subclass 285.2) Subject matter wherein the "tab stop" elements are arranged on the tab-rack* in sets or assemblages of tab stops, the individual tab stops of each set being in an ascending or descending scale of individually varying length in each assemblage, and each set or assemblage being arranged for a different "columnar" arrangement.

(1) Note. The term "tab stop" is discussed in the definition of tab-rack in the Glossary, section III, and the term "columnar" is a variation of the term "column" which is discussed in (1) Note of subclass 284.
