Definitions

  • Fig, 2 is a perspective view of the tabulating and lock-out mechanisms applied to said printing apparatus
  • Fig. 3 is a transverse cross-sectional view of the printer in accordance with said patent, taken approximately through the vertical center line of Fig. 1;
  • Fig. 6 is a sectional plan view of the printing apparatus corresponding to Fig. 11 in Patent No. 1,904,164, with the addition of the tabulating and lock-out mechanisms of the present invention, and
  • the selector vanes as set forth in Patent No. 1,904,164 control a series of function levers among which and provided especially for accomplishing 15 the objects of the present invention are a tabulating function lever 45 (Fig. 'l) and a lock-out function lever I33 (Fig. 3), which like the other function levers'described in said patent are pivoted on a common pivot rod 43 and are assemso bled in a slot in the function lever comb 41.
  • These function levers 45 and I33 like the rest of the function levers of the series, are provided with individual springs 43 and I34, respectively. tensioned between each and the printer frame as which tend to rotate the respective function levers 45 or I33 about pivot 46 but, as clearly set forth in Patent No. 1,904,164, are restrained by the function lever ball 46 acting through rod 56 on arm I36.
  • Ratchet 52 is thus restrained from rotation by lever 63 until the completion of the printing of a character at which time printing bail 43 and associated lever 84 are caused to rotate in the opposite direction by the action of a printing cam (not shown). Restraint of lever 82 by lever 84 through end II is thereby removed, permitting lever 82 to rotate in a counterclockwise direction under the influence of spring 65 into the path of tooth Nb of ratchet 52.

  • a traveling carriage cooperating therewith, means for effecting the normal spacing movement of said carriage, other means for effecting the continuous movement of said carriage through variable sequences of character spaces, and further means for automatically and simultaneously rendering said recording mechanism and said first and second recited means inoperative after said carriage has reached a predetermined position.
  • a carriage movable to form character spaces, a spacing mechanism therefor normally adapted to control the advancement of said carriage one character space upon each operation thereof, said spacing mechanism comprising a pair of spring-biased pawls acting to afford an escapement therefor, permutation code mechanismto control operations other than recording comprising a plurality of function code levers.tabulatingmechanism operative in response to the selective operation of a certain one of said levers to effect, through the instrumentality of said lever, the disablement of one of said pair of pawls to control the advancement of said carriage continuouslythroughapluralityof spaces at a time, and means effective when said carriage has reached a predetermined position to render said tabulating mechanism unable to effeet the disablement of said one of said pair of pawls.
  • means to efi'ect recording operations means to limit the movement of said means to a single character space at a time, means to render said second recited means ineffective to limit the movement of said first recited means to single spaces, and means efifective under predetermined operating conditicns to prevent the operation of said last recited means.
