718,737. Statistical apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 13, 1952 [June 12, 1951], No. 12088/52. Class 106 (1) The apparatus comprises means for entering into an accumulator and/or printing a pence column having digits 0-11 from a single record card column, in place of the usual two columns. The record card is provided with X and R designations and digit designations, Fig. 8, and the apparatus comprises two storage means one for controlling the entry of 1 and the other 2 in addition to a 1-9 digit entry. There is provided means for sensing the X and R designations and means controlled thereby for selecting the associated storage .means. an accumulator wheel, an accumulator wheel clutch, and means controlled by the selected storage means to cause the accumulator wheel to enter an additional 1 or 2 to make the amount entered 10 or 11 according to the storage means selected. The accumulator is of known construction and the variable speed drive for the printer is also of known construction. The card analysing mechanism is also of known form. The apparatus is provided with a printing mechanism of known form which is adapted to print as shown in Fig. 9 the amounts in pounds, shillings and pence. The units pence order of the printer has a type wheel 60 which prints the pence 0-9 and on the same wheel as shown in Fig. 1a the numbers 10 and 11 are provided to print these pence amounts. The pence type 0-9 as well as the units and tens of the shi'lings and pounds orders are selected by the card holes at 0-9 index positions but 10 and 11 type are not directly selected by the X and R holes since, such holes select an impulse transmitting means which transmits impulses 9-4 or 9-3 which through a translator of known type enables the printing wheel to be rotated to a position to print the 10 or 11 pence type shown by the code'set out in Fig. 7. Sensing of the X or R holes which represent 10 or 11 pence respectively is effected at the first reading station, one machine cycle prior to the 10 or 11 entry which is effected in the second machine cycle. To this end the p!ug socket 270. Fig. 11 a, pertaining to column 13 has a plug wire connection 277 ending at a plug socket 278, thus directing the impulse at X or R time to this socket to selectively energize the R10 relay or R11 relay which are set up to represent 10 or 11 pence. It will be seen from the timing diagram, Fig. 10b, and the circuit shown in Fig. 11d that the R13 relay is energized by CF102 cam contacts when both X and R impulses are being transmitted and R12 re'ay is energized by CF101 cam contacts only when the R impulse is transmitted. If both relays are energized at the R impulse time the R impulse from plug socket 278, Fig. 11a, is directed through the R13-1 relay contacts, now closed, the R12-1 re'ay contacts, now transferred, the R11 relay to line side 267. When the X impulse is transmitted the R12-1 contacts will not be transferred at this time so, that the X impulse will be directed through the R13-1 relay contacts, R12-1 normally closed relay contacts, to pick up coil of R10 relay, to line side 267. If either R10 or R11 relay is energized a hold circuit is provided through the respective " 1 " hold contact, cam contacts CF103, back to line side 266. As is well known " CF " contacts are closed only during card feed and card sensing cycles. Thus, either the R10 or R11 relay or both are maintained energized from the time of their energization to 330 degrees of the same cycle, while the card is transported to the second reading station. The 1-9 impulses directed to plug socket 272 for the pence order pass through normally closed contacts R15-3, R16-3, R8-2, R18-2 and R8-3, contacts, as previously described to transmit an impulse to the magnet for the pence order when 1-9 pence are to be printed and accumulated, When either 10 or 11 pence is to be printed and accumulated the openmg of either contacts R15-3 or R16-3 will open this impulse circuit and causes either CR202 or CR201 cam contacts to transmit 9-3 or 9-4 combinational impulses to the magnet. The impulse circuit for 9-3 impulses when R15 relay is energized is from line side 266, CR202 cam contacts, R15-3 relay contacts now transferred, R16-3 contacts now normal, R8-2 relay contacts now normal, R18-2 contacts, R8-3 contacts, plug socket 273, plug wire 274, pence order print control magnet to line side 267. This effects printing of 10 pence, for 11 pence R16-3 relay contacts would be transferred and CR201 cam contacts would transmit 9-4 combinational impulses to the pence order print control magnet by a similar energizing circuit. A 9-4 combination impulse will condition the translator to cause link 63 to be shifted at about 105 degrees of the cycle, Figs. 1a, 10a, thus engaging the type wheel clutch to cause a rotation of the pence printing wheel 60 to select " 11 " whereas the 9-3 combination causes a movement of link 63 later in the cycle to cause type wheel 60 to be rotated a lesser extent to select the " 10 " type on the pence printing wheel 60. In the preferred form accumulating entries are made under control of the type wheel clutches, but entries may be made directly under control of the perforated record, by omitting plug connections 274 and 280. so as to render the printing mechanism inoperative, with other minor circuit modifications. Zero print control.-Zeros are printed in the units of pounds order, the units of shillings and the pence orders, but are omitted from the tens of shillings order. To effect this, a known form of zero print control is employed. In general the 0 is printed in the units of pounds order under control of the zero hold in the related column when the next higher order or tens of pounds column represents a significant digit 1-9. When the 0 is not to be printed, as in the tens of shillings order, this intercontrolled plugging is omitted. The zero is printed. in the pence column, units of shillings column, dependent on printing a significant digit 1-9 in the next higher order column. This form of zero, print control will cause printing on a result sheet as shown in Fig. 9,
