Abstract: 534,334. Calculating-apparatus. ADDRESSOGRAPH-MULTIGRAPH CORPORATION. July 28, 1939, No. 21961. Convention date, July 28, 1938. [Class 106 (i)] A machine for effecting multiplication comprises summation means which includes detecting or sensing elements for co-operation with members arranged in groups and shaped to represent intermediate products, and with means for effecting engagement movement between the elements and members, means being provided whereby the accumulated relative movements are summed up to obtain the denominational values of the final product. The intermediate products are formed on gangs of templets that are shaped or stepped to represent the product of the digits by all the digits of a fixed multiplicand or by a single digit of a variable multiplicand. In the first case the transfers incidental to the digit by digit multiplication are carried over in the templets themselves, in the second case the transfers are made by the summation means along with the incidental transfers. The mechanism described forms part of the machine described in Specification 534,335, which operates under the control of printing and control plates fed in sequence through the machine and from which the data is sensed to produce a record and print matter on sheets constituting cheques or dividend warrants. The printing and control plates each include an embossed plate bearing fixed data and a control card with perforations according to a code representing particulars of the shareholding &c. of a person to whom the plate relates. Factor entering means.-In one form of mechanism described, one of the factors, the multiplicand or dividend rate, is constant for a series of operations ; the gang of templets 1105 ... 1108, Fig. 56, bear representations of the intermediate products obtained when the constant factor 999 is multiplied by the digits 1 to 9 and 0. A gang of templets is provided for each denomination of the multiplier and each gang is provided with a positioning templet 1117. The templets in each gang are arranged on a sleeve 1118, Fig. 25, with spacing collars 1120 ... 1122, and a nut 1123, the whole being supported on a pin 1172 removably mounted in bearings 1166, 1167 secured to frame plates 1124, 1125. The gangs of templets for the three denominations, units, tens, and hundreds, of the multiplicand are disposed on pins 1193, 1185 and 1172 arranged as shown in Fig. 21 and the particular orders of the templets for a threefigure multiplier are disposed adjacent denominational plates 1126 ... 1131, Fig. 25, mounted between the frame plates and on which the summation means is mounted. The positioning templet 1117 for each denomination is stepped as shown in Fig. 56 to take account of the code perforations wherein two perforations are provided for the odd digits 1, 3, 5 and 7 and a single perforation is provided for the even digits 2, 4, 6 and 8 and the odd digit 9 ; in this arrangement a perforation appears in the 9 position when the odd digits 1, 3, 5 and 7 are represented. The setting of each templet 1117, for the other factor, is effected under the control of a denominational detector which senses the control card and transmits the movement of feeler pins through Bowden cables 1532, Fig. 25, to push pins 1547. Each set of pins 1547 is mounted on an arm 1539 that is journalled on a pin 1540 in a bearing block carried by the frame plate 1125. The arm 1539 for the hundreds denomination is shown in Figs. 25 and 26 and is controlled by a spring 1543 for limited movement between stops 1545, 1577. The rocking movement of the templets 1117 is effected by springs 1558 ... 1560 attached to slides 1548, 1549 on the frame plate 1125, Fig. 21, the slides being connected by a lever 1556 to a shaft 1557 operatively connected through a linkage 1569, 1570, 1572 to a cam on the main cam shaft 1280. The " 9 " pin when projected for its own digit or any one of the other odd digits engages a shoulder on a block 1567 secured in a slot in the frame member and thus holds the arm 1539 against the stop 1545 to limit the swing of the templet 1117 in accordance with the odd digit represented. For the even digits the " 9 " pin remains in retracted position so that the templet 1117, on its movement, contacts the pin for the even digit represented and carries the arm 1539 an additional step with the templet to engage the stop 1577. In the restoring movement pins 1561 ... 1563 engage the templets 1117 to return them to normal position and an operative connection with a cam on the main shaft reciprocates a plate 1591, Fig. 25, to retract the projected pins 1547 and Bowden cables. Summation means.-The summation means is mounted on the denominational plates 1126 ... 1131, the plate 1128 associated with the hundreds denomination is shown in Figs. 36 and 37, and carries a final product receiver rack 1141 meshing with a transfer pinion 1146 on the adjacent plate 1129 and with a pinion 1147 on a slide 1148 supported on the plate 1128. The plate 1128 also carries a fixed rack 1194, slides 1163, 1182 and 1190 with pinions 1162, 1181 and 1189 with inter-engaging slide racks 1160, 1178 and 1187. The pinion slides are provided with feelers 1154, 1164, 1183 and 1191 for co-operation with a transfer stepped arm of a bell crank 1157 controlled by the next lower denomination and with the templets 1107, 1106 and 1105 of the units, tens and hundreds denominations. The denominational plates are of uniform construction but the parts carried thereon vary with the denominational order and can be omitted or replaced by fixed elements if they do not have to co-operate with a templet set or with a transfer member. When a summation is to be effected each receiver rack, such as 1141, is moved downwardly by the action of cams on the cam shaft 1280 rocking a lever 1274 to depress a bar 1262 which, through a member 1264 on a block 1265 slidable on upright posts 1267, pulls on springs 1271 attached to the member 1264 and to a foot plate 1261 on the receiver rack 1141. The shaft 1275 of the lever 1274 is mounted on a rocker to ensure that the bar 1262 is returned to a position to force every sensing finger back to its zero position. Each receiver moves downwardly under the successive action of its feelers to present one or other set of its stepped elements 1320 to the stepped end of sensing bars 1324. Transfer mechanism.-Regarding the carry over from the tens to the hundreds denomination the tens receiver 1195 (not shown) drives the transfer pinion 1146 on the hundreds plate 1128, Fig. 36. At the commencement of an operation a cam on the main shaft 1280 through a lever 1602, Fig. 4, rocks a lever 1209 and a pin 1208 thereon frees a bell crank 1204 to the action of its spring 1219 and permits a threearmed lever 1201, carried by the bell crank, to move one of its arms into engagement with a double cam 1197 integral with the transfer pinion 1146 as shown in Fig. 52. As the receiver 1195 moves the cam first depresses the lever 1201 so that its end engages ratchet teeth 1221 on a bell crank 1218 and then in passing the lobe of the cam the lever 1201 is raised by the spring 1219 to advance the bell crank 1218 one step. This movement moves the templet end 1155 of the bell crank 1218 one step which is picked up by the feeler 1154 on the slide 1148. Additional transfer movements are effected similarly. Overthrow action of the lever 1201 is prevented by the lower end of the arm 1204 co-operating with other ratchet teeth 1224 on the bell crank 1218. At the end of the operation the lever 1209 is again rocked to move the levers 1201 and 1204 to inoperative position, a spring 1222 restoring the bell crank 1218 to normal position. Printing mechanism.-After the receivers have been set a cam on the main shaft 1280 through a follower 1339, Fig. 1, rocks a shaft 1338 with arms 1337 carrying a roller 1335 engaging a depending arm 1334 on the sensing bars 1324 which under the action of springs 1331 move to take up positions in accordance with the setting of the receivers. The receivers carry racks 1345 engaging gear segments of type members 247 from which the final product is recorded by the action of a platen 250. The type segments 247 as shown in Fig. 8 are for dollars and cents, the cents segments always print zero in normal position but the dollar segments have a blanking character BC when printing is not desired. This control of zero printing is effected by mounting the racks 1345 in a slidable manner on the sensing bars and by controlling their position against the action of springs 1350<SP>1</SP> by pawls 1350 associated with the dollar segments. The pawls 1350, Figs, 1, 4 and 39, are pivoted on a shaft carried by an arm of a bell crank 1353 with a cam surface on its other arm engaging a roller on the axis of the roller 1335. Shoulders on the pawls are urged into engagement with lugs 1349 on the racks 1345 when the tapered ends of the pawls are freed from engagement with a pin 1358, on the movement of the bell crank 1353. If, in the meantime, any dollar racks have been set to a significant digit the corresponding lugs have escaped past the shoulder on the pawls, but those lugs to the left of the highest digit are arrested by the shoulders and the racks are displaced thereby to reverse the type segments and bring the blank character BC to the printing position. Zeros to the right are printed by providing the pawls with a lateral extension extending beneath the pawl of next lower order. The gear segment 1346 is formed with a notched extension 1389 co-operating with a block 1390 to align the type segments during a printing operation. Punching mechanism. The result determined by the multiplying mechanism is punched on a card C, Figs. 1 and 4, fed from a magazine 1432 to punch slides 1400 each connected to a sensing bar 1324. Each slide 1400, Figs. 9 and 10, carries a punch 1407 with a T-shaped head engaging a corresponding slot in a block 1412 carried on posts 1414
