Abstract: 517,067. Checking receipts. BRITISH TABULATING MACHINE CO., Ltd. June 28, 1938, No.  19193. Convention date, June 29, 1937. [Class 106 (i)] [Also in Groups VIII and XVI] Method of, and apparatus for, punching a statistical record card and simultaneously printing on the card an interpretation of the punching, consists in printing the characters related to selected card columns along different rows (at right angles to the columns) of the card with each character aligned with its related column. In the construction illustrated two rows. at the top and bottom of the card, are used whereby each character has double the normal spacing allotted to it and may therefore be printed larger. To deal with twenty card columns, ten slidable punch bars 14 are used. Each punch bar occupies the width of two card columns and carries a punch 17 and die 18 and two sets of type 32t and 32b. The left hand type Fig. 3, of each set carries type" O," the next to the right " type 1 " and so on. The card is inserted in slot 16, from the right in Fig. 1, and by means of its holes 68, Fig. 10, being positioned on lugs 67, Fig. 1, on the card carriage C, the card is positioned so that the two " O " types on each bar are at the top' and bottom of the card column and-the punch 17 is over the " O hole position of the column. Each bar 14 has ten holes 14a, Fig. 1, and by inserting a stylus in any hole, say " 6," and drawing the stylus forward until it is arrested by a fixed datum bar. 33, the bar 14 is selectively set so that the punch 17 is over the " 6 " hole position and the " 6 " type 32t and 32b are over the printing line at the top and bottom of the card respectively. The punches pass through slots 19, Fig. 3, in a restoring plate 20 and have cross pins 23 which are positioned between the solid parts of plate 20 and a pressure plate 21. Plates 20 and 21 are rigid with one another and to effect punching the plates 20, 21 are lowered by linkage 25, 25<SP>1</SP> and cam 29 on a shaft 30 to which is attached an operating handle 31, Fig. 2 (not shown). Each set of type 32t and 32b coacts with a hammer 36t and 36b respectively and one or other set of hammers may be locked out of action. In the present arrangement the odd - numbered card columns are punched and their punched value is simultaneously printed at the top of those columns. The card is then moved one column sideways (to the left Fig. 1). the bars 14 have a new setting given to them, 'and the even-numbered card columns are punched and their punched value is printed at the bottom of those columns. When the above-mentioned cam 29 is rocked to effect punching, it also causes hammer-release so that printing can be effected. Selecting means is provided to decide which set of hammers are so tripped. The ten hammers 36t pivot on a fixed rod 37 and the ten hammers 36b pivot on a fixed rod 37<SP>1</SP>. Each hammer 36t or 36b is latched down bv a latch 38t or 38b pivoted upon a fixed rod 138t or 138b. Slidable upon rods 37, 37<SP>1 </SP>is a rectangular hammer-reset. frame composed of bars 42, 43 and cross rods 44 and 45. Rods 44, 45 on movement to the right, Fig. 3, reset any unlatched hammers. Pivoted to bar 43 is an arm 46 having a roller 47 which is controlled by the edge of the cam 29. A latch-release frame, consisting of arms 49, 49<SP>1</SP> joined by cross rods 51t, 51b is pivoted by two pins 50 on to the hammer-reset frame and carried left and right therewith under control of pin 47 and cam 29. Rods 51t and 51b coact with tails of the latches 38t and 38b, according to the angular setting of arms 49, 49<SP>1 </SP>to trip the hammers. In the position shown the rods 51t and 51b on moving to the left leave the latches unaffected. If arms 49, 49<SP>1 </SP>are rocked clockwise or counter-clockwise, the rod 51b or 51t respectively rocks the latches 38b or 38t to effect printing at the bottom or top of the card columns respectively. The rocking of arms 49, 49<SP>1</SP> is effected by a U-shaped piece 52, on the side of arm 49, Fig. 9. which coacts with a fairly long pin 53 fixed to a plate 54 which is pivoted on a shaft 55 and has a hole and pin connection 58, 59 with a handle 60 (see also Fig. 1). The latter is fastened to a yoke 61 hinged on a pin 62 carried on a block 63 fixed to shaft 55. With pin 59 in hole 58 the frame 49, 49<SP>1</SP>, 51t, 51b may be rocked to trip either set of hammers 36t, 36b. With pin 59 and hole 58 disengaged printing is not effected, but only punching. For this, the handle 60 must be moved halfway, Fig. 1, before is can pass through the central slot of the H- shaped slot 74, to move laterally and disengage pin 59 and hole 58. The disengagement is thus effected when the parts are in the position shown in Fig. 3, with rods 51t and 51b below all the hammer latches. The handle 60 also controls the position of the card carriage C, Fig. 1, so that with the handle in the position shown in Fig. 1 the card is so positioned that the punches are over the odd-numbered columns. If the handle is moved to the right-hand end of the slot 74 the card is placed to receive punching in the even-numbered columns. For printing at the top or bottom of the card columns, the handle 60 must be at the left or right hand end respectively of the lower part of slot 74 as indicated in Fig. 1. In a modification, Fig. 11 (not shown), the handle 60 is not associated with the printing controls, but there is provided a print control slide for each pair of hammer latches related to one card column. Each slide may be manually set so that it locks one or other or both hammer latches.
