  • Raised portion 69 also defines an inclined edge 74 which is symmetrical with the edge 66 of raised portion 63.
  • a zeroizing member defined by a tongue 76 is normally engaged by the groove between raised portions 63 and 69, i.e. when drum 57 is in the datum position, and is engageable by edge 74 or by the edge 66 of raised portion 63 for moving the drum back to the datum position after one of the edges 66 has disengaged the projection 56 of a set slider 44, i.e. after the drum has been shifted in the second direction.

  • Drum 57 in addition to raised portions 62, 63, 64, 65, 69, 73 and 78 (FIG. 2) hereinbefore described, also is provided with a second series of raised portions 62', 63', 64, 65',69', 73', and 78' similar to the first-mentioned raised portions.
  • Raised portions 62, 63, 64, 65, 69 and 73 occupy an angular development of 90, with inclined edges 66 and 74 occupying 80 and rectilinear edges 67, 68, 71 and 72 occupying 10; while raised portions 78 are circumferentially adjacent the first-mentioned raised portions and occupy an angular development of another 80.
  • Projections 56 (FIG. 3) of sliders 44 are spaced from tongue 76 by about 90.
  • the device also includes means for rotating sleeve 60 to thereby rotate drum 57 with respect to sliders 44.
  • Such means include a pinion 107 (FIG. 1) fixed to sleeve 60 and a gear 108 which meshes with the pinion.
  • Gear 108 includes a hub 109 having a series of radial slots 110 therein, two of which are normally engaged by two pins 111 fixed to shaft 84.
  • the transmission ratio between gear 108 and pinion 107 is such that by rotating shaft 84 through 45, i.e. one angular step, sleeve 60 is rotated through 180.
  • the number of series of raised portions on the drum is two (one series comprising portions 62, 63, 64, 65, 69, 73 and 78 and the other series comprising portions 62', 63', 64', 65, 69, 73 and 78').
  • the drum could be rotated a greater or lesser fraction of a revolution for each transfer cycle, in which instance a greater or lesser number of series of raised portions would be required.
  • the number of series of raised portions required is the positive integer which equals the denominator of such revolutional fraction, the numerator thereof being unity.
  • sliders 81 of setting store are at a datum position representing the digit zero, as shown in FIG. 1.
  • the respective shank 34 (FIG. 3) is pivoted counterclockwise about the associated projection 41.
  • Projection 50 of the pivoted shank 34 then acts on the corresponding slider 44 to shift such slider to the right as seen in the drawings, i.e. setting the slider.
  • the projection 56 of the set slider 44 is then brought into the path of one of the inclined edges 66 (FIG. 2) of drum 57.
  • Shaft 84 is then rotated clockwise through one angular step by a conventional drive means (not shown) which causes the pinion 107 to rotate counterclockwise through together with sleeve 60 and drum 57.
  • drum 83 (FIG. 3) is rotated clockwise with a reduction ratio of l/4 with respect to drum 57.
  • the slider 81 which is to be set (in FIG. 3 the one immediately below the plane defined by the axes of shafts 61 and 84) is brought into correspondence with interruption 94 at the instant when drum 57 is positioned exactly as described hereinbefore, i.e. when the engaged projection 56 passes through the groove partially defined by the section 67 of the engaging inclined edge 66.
  • the rectilinear section 67 (FIG. 2) disengages the projection 56 of the slider 44 which has been set. Raised portions 78 then engage teeth 92 of the slider 81 to be set, connecting such slider to drum 57.

  • raised portions 78 shift the slider 81 to be set (FIG. 1) axially of drum 83 so that such slider is set by a stroke equal and opposite to the previous axial movement of drum 57, the slider thus being brought into a position corresponding to the digit of the key 23, 24 depressed.
  • tongue 76 is engaged by parallel sections 67 and 68' (FIG. 2), while raised portions 78' disengage the set slider 81 (FIG. 1).
  • the setting of the digit zero does not entail any axial shifting of drum 57 or of the slider 81 to be set
  • the setting of the digit five entails the shifting of drum 57 by one step, as a result of which the slider 81 to be set is shifted downwardly, as seen in the drawings, by one step.
  • the setting of the digits lower than five entails a shifting of the slider 81 to be set upwardly from the zero position by a corresponding number of steps
  • the setting of the digits higher than five entails a shifting of the slider to be set downwardly by a number of steps equal to the difference between the digit to be set and five, starting from the five position.
  • Each slider 81 also is provided with a tooth 220 (FIG. 1) which is adapted to be read by one of ten sliders 216 corresponding to the digits zero through nine. Sliders 216 transfer the numerical data represented by the positions of teeth 220, and therefore of sliders 81, to the accumulator of the calculating machine.
  • Each slider 81 is moreover provided with a zeroizing projection defined by a tooth 221 adapted to cooperate with another drum 222 which is fixed on shaft 61 and also preferably is made from a plastic material.
  • Drum 222 is provided with two raised portions 223 and 224 defining inclined edges 226 and 227, respectively, (FIG. 2) which converge toward each other and define a groove 228 therebetween.
  • drum 83 is shiftable axially to disengage pins 111 and to engage pins 230 to thereby connect the drum to shaft 91. Thereafter, by rotating shaft 91, drum 83 also is rotated.
