(under subclass 371) Framed typed devices having means for applying tension to the fabric therein.
(1) Note. Since all fabric fastening means of the type in which one element provides a channel or groove into which a second fastening element is forced to have an inherent tendency to apply a stretching force to the fabric, such devices have not been placed here but will be found below and cross referenced to subclass 382 and indented subclasses (particularly subclasses 395+); and when the fabric fastening means, per se, (as defined in subclass 382 and explained in the notes) is recited, the patents have been placed there (subclasses 382+), as originals.
SEE OR SEARCH THIS CLASS, SUBCLASS:
