DEFINITION

Classification: 83/251

(under subclass 250) Device so constructed that work may be moved by more than one feed means acting at different times.

(1) Note. This subclass includes lateral positioning means, for instance.

(2) Note. This subclass includes work-feed means which may not be effective in every cycle, such as manually actuated means to correct the registry of the work, either by the provision of additional work-feed means or by provision of additional actuating means for the existing work-feed means.

(3) Note. The search notes under subclass 250 should be reviewed in relation to this and indented subclasses.

(4) Note. Supplemental work-feed means, in this and indented subclasses, is capable of and is normally utilized for the purpose of presenting work in correct amount and proper timed relation to the tool station, as distinguished from work transport means which merely forwards work to a work-feed means proper and which lacks the requisite timing

or range of stroke to position the work for operation thereon by the tool.
