Abstract: 445,846. Selective punching-machines. REMINGTON RAND, Inc., 465, Washington Street, Buffalo, New York, U.S.A. July 18, 1934, No. 21015. Void [Abridged as open to inspection under Sect. 91 of the Acts, Jan. 19, 1935]. [Class 31 (ii)] [See also Groups XV and XVI] Punching-apparatus is provided with cardsensing means, a transposer, and punches whereby the data read from one set of perforated code cards is transmitted by the transposer to the punches, in a changed form so that a second set of cards is punched which contains the same data as the first set, but perforated according to a different code. The transposer is readily interchangeable as a unit so that the first set of cards may be reproduced in various desired code forms. If desired the second set may be an exact duplicate of the first set of cards. The card-reading pins 14, Fig. 3, are housed in the top section 10, Fig. 1 ; 11 is the interchangeable transposer, and the punches 24 are housed in the punch section 12. 27 (see also Fig. 19) is a settable device for limiting the machine to a predetermined number of cycles. When the pin-box is lowered, pins 14 which read holes in the card 15 are latched down by plate 17 and depress corresponding interposer rods 18 in the transposer 11 and punch gags 19, which latter are locked down by plate 21 and subsequently cause the appropriate punches 24 to perforate the card 25. By disabling the resetting means 26 for the plate 21, data may be set up on punch gags 19 from two successive cards 15 and be used to perforate a single card 25. Fig. 12 shows a transposer unit 11 and as the rods 18 are shown in Figs. 3 and 12 they are arranged to produce a card 25 which is an exact reproduction of card 15. The unit 11 is held in place in the machine by finger latch members 102. If it is desired to transpose from one code to another then, in the transposer unit used, the wires 146, Fig. 26 are cross-connected so that if, say, a " O " hole is read in card 15 by the seventh pin 14 from the left, a " O " hole is punched in the lower card by the third punch from the left which is cross-connected to said seventh pin. By using a special sensing head, cards 15 which have rectangular holes may be dealt with. In the construction shown in Fig. 32, cards 15 punched according to a onehole code may be reproduced by punches 24 as cards perforated to a two-hole code. For example, the fifth pin 14 from the left, reading the numeral " 2 " operates the third rod 147 from the left which is connected by a lug 149 to the second rod 147 ; the latter coacts through a lug 151 with the last rod 147 on the right. Hence when " 2 " is read in the upper card, the second and last punches 24 from the left punch holes to represent " 2 " in the lower card. In another construction, using six punches, the second card is punched according to a six-point code in which each digit is represented by two holes. Fig. 46 shows the cross-connections necessary in the unit 11 to transpose a four-point Borel- Siemens-Halske code card read by pins 14 into a Hollerith type card. Operating apparatus for a predetermined number of cycles. Two ratchet wheels 104, Fig. 19, are rigid with manually settable knobs 106. One wheel has one hundred teeth, the hundredth tooth space being of double depth. The other ratchet has twelve teeth. A scale plate 107 has an opening for reading graduations on the forward, hundred-toothed ratchet and a pointer for indicating the position of the twelve-toothed ratchet. Pawl 108 holds the ratchets 104 against accidental displacement. Ratchet driving pawl 111 is operated by arm 109 and eccentric 71 from a shaft 56 which makes one revolution for each card dealt with. The pawl 111 rotates the hundred-toothed ratchet 104 tooth by tooth until it falls into the deep notch whereafter it drives discs 104 together. When both discs 104 reach zero position a lug 112 on the twelve-toothed disc rocks bell-crank 113 and operates Bowden wire core 114 to disable the main driving clutch and stop the machine. Printing-mechanism. When the card holes of the top card in the machine are read, the lowering of rods in the transposer operates Bowden wires 238, Fig. 44, which depress the appropriate stops in a series of stops 225- 230. Each stop coacts with a lug 224 on a rack 212 geared to a printing wheel 216 so that when the racks are released by bail 231 they are moved by sectors 222 to the right until their lugs 224 are held by the lowered stops and the type wheels are set accordingly. In the modification shown in Fig. 58, the data read are conveyed in two stages from the five-point-code card 15 to the transposer unit 11. When one or more of the five pins 14 for each card column senses a hole it depresses its corresponding wire 281, the lower end of which thus blocks its corresponding slide 284. After the pins 14 have sensed, springs 285 press slides 284, bearing holes in them, to the left. One or more of slides 284 will be blocked by a lowered wire 281 so that when pin-box 288 is lowered to sense the holes in the five slides 284, they will depress the rods in the transposer 11 according to the positional combination of the slides 284. In Fig. 58 the transposer rods in unit 11 are vertical for a duodecimal reproduction in the lower card which is to be punched, but the transposer rods may be cross-connected to give various other code forms according to the transposer arrangements described above. In order that the apparatus may be used as an ordinary keyboard punching mechanism, the transposer unit 11, such as shown in Fig. 12, is removed and replaced by a keyboard basket 301 as shown in Fig. 63. The keyboard 323 then controls the punches in the section 12, Fig. 1, in a usual manner in order to punch cards as desired; depressor bars 309 being actuated by the keys and directly depressing the punches. These depressor bars coact with the punches column by column, the carriage bearing the basket 301 moving laterally under control of a spring drive 338 and escapement mechanism which acts each time a bar 309 is depressed. In using a transposer unit to produce, from the upper cards 15, the lower cards 25 which are punched in the section 12, it may be desired to punch in the lower cards additional data which is not in the upper cards. For this a transposer unit as shown in Fig. 70 is used. The usual transposer rods are present and there are additional rods 391 which actuate some of the punches 24 and are operated from the linkage 387 and 388 and the auxiliary keyboard (sliding key rods 386), which form part of the transposer unit.
