Abstract

Corner cut sensing lever 10 is pivotally connected to support 11 about the axis of pin 12. The mass of lever 10 is distributed with respect to the axis of pin 12 to cause the distal end portions of stop arm 13 and actuating cam 14 to normally drop by gravity into recesses in upper card guiding surface 15 of bed plate 16 as in A. Arm 13 is positioned in the path of the near transverse margin of a card 17 progressing along card guide surface 15 and actuating cam 14 is positioned in the path of the far transverse marginal portion of such a card. As in A and B, lever 10 is oriented to pass a card 17 moving in the direction of arrow 2 which has a corner cut on the near side leading corner and block a card 17 not possessing such a corner cut.

Corner Cut Sensing Lever

Corner cut sensing lever 10 is pivotally connected to support 11 about the axis of pin 12. The mass of lever 10 is distributed with respect to the axis of pin 12 to cause the distal end portions of stop arm 13 and actuating cam 14 to normally drop by gravity into recesses in upper card guiding surface 15 of bed plate 16 as in A. Arm 13 is positioned in the path of the near transverse margin of a card 17 progressing along card guide surface 15 and actuating cam 14 is positioned in the path of the far transverse marginal portion of such a card. As in A and B, lever 10 is oriented to pass a card 17 moving in the direction of arrow 2 which has a corner cut on the near side leading corner and block a card 17 not possessing such a corner cut. As in A, card 17 progressing in the direction of arrow 2 with the leading edge corner cut at the far transverse side is stopped by abutment with stop arm 13. When the corner cut is disposed at the near side of the leading edge, as in B, card 19 is permitted to pass beneath lever 10 as the leading edge initially engages and pivots actuating cam 14 causing operation of arm 13. This pivots in unison with cam 14 and is removed from a position of interference with card 19.
