Abstract

The selective transfer punch is used for transfer punching precoded data on a master template to a prescored punch card. To operate, master template 2 is inserted on template shelf 4 and prescored punch card 6 is placed on its support 7, and operating button 8 is depressed. During such depression, interposer 10 is shifted laterally by cam surface 12 carried by end support upright 14 and cam surface 16 on the end of interposer 10. The lateral shifting of interposer 10 captures and locks the heads of selected styli 18 which pass through precoded holes 20 in template 2. Those styli 22 which encounter the imperforate portion of template 2 are displaced upward relative to stylus block 24, escaping the locking action of interposer 10.

Selective Variable Punch

The selective transfer punch is used for transfer punching precoded data on a master template to a prescored punch card. To operate, master template 2 is inserted on template shelf 4 and prescored punch card 6 is placed on its support 7, and operating button 8 is depressed. During such depression, interposer 10 is shifted laterally by cam surface 12 carried by end support upright 14 and cam surface 16 on the end of interposer 10. The lateral shifting of interposer 10 captures and locks the heads of selected styli 18 which pass through precoded holes 20 in template 2. Those styli 22 which encounter the imperforate portion of template 2 are displaced upward relative to stylus block 24, escaping the locking action of interposer 10. The continued downward thrust of button 8 forces the selected and locked styli 18 through template 2 and through card 6, accomplishing the desired transfer of the precoded information. The punch is restored to its rest position by springs, not shown, between block 24 and stylus guide 26. Styli 22 are reset by stylus reset plate 28 which is carried by the end support uprights 14 of the punch frame. The shifting of interposer 10 secures only those punches encountering holes in the master template and does not affect the axial movement of the remainder of the punches.
