conclusion that it did "not disclose the particular improved disconnecting mechanism consisting of the cam and swinging roller which are essential elements of claim 3".

An earlier Belknap patent No. 889,503, while it provided for holding the printing mechanism inoperative, had no means for stopping the feed of stencils also.

The patent was held valid.

[It seems to be difficult to reconcile this decision with the McNeil line of decisions and with the unvarying line of Supreme Court decisions on Aggregation, even if these be modified by Oshkosh Grass Matting Co. v. Waite Grass Carpet Co. 207 F. 937.]
