[Also in Group XIX] An accounting-machine having a transversely - movable paper carriage carrying function-control means is provided with punching mechanism set with or by the calculating mechanism and includes a device for storing several multidigit numbers (as described, in coded form), this device being movable, after the several numbers have been set, to effect punching. The invention is applied to a machine similar to that described in Specification 749,504, [Group XIX], with a single-bank keyboard 2, Fig. 1, for setting a pin carriage 4 controlling actuators 5 associated with two totalizers 7, 8 and type wheels 6. A roller platen 11 is mounted on a carriage 12 which carries adjustable stops 18 for actuating control levers 19 in accordance with the columnar position of the carriage. The punching unit is provided with its own electric motor and is mounted in a housing supported at the rear of the machine on a frame 38 secured to its base 1. The circuit of the punching unit motor is closed during setting operations over contacts 236, 237, Fig. 4, controlled by a one-revolution clutch 131, 132 tripped as described below, and during tabulating, return or punching movements of the storage device by contacts 232, 233, Fig. 1, controlled by a lever 125 referred to below. Storage device. This comprises eighty-four rows each of five pins 58, Fig. 2, mounted between plates 79 spaced by side walls 80 and movable transversely of the machine in guides 86. Each row of five pins stores a decimal digit in coded form, the pins being held in set (upward) or normal positions by a detent slide 59 associated with the row. The detent slides may be shifted to cancel set digits by bars 84, 85, one or both of which may be notched so as to cancel only the numbers stored in certain columns. In a modification, Fig. 9 (not shown), a slide is positioned according to the number of denominations in the column into which entry is to be made (by means of the pawl 118 which, as described below, controls the punching of zeros) and is then moved by a cam in a perpendicular direction so as to operate a corresponding number of detent slides to cancel any settings in that column prior to the new entry. Setting storage device in code. The differential actuators 5, Fig. 2, which during a cycle of the accounting-machine, take up positions corresponding to the digits set in the pin carriage 4, are connected to links 36 having transverse end-pieces 45, 46 guided for movement over a plate 211 forming part of a stirrup 49. When the links 36 are differentially set, a link 25, Fig. 1, is engaged by a stud 24SP1/SP in an arm on the mainshaft of the accounting- machine and, if a carriage-controlled pendant 28 is effective, a slide 29 is shifted to trip a onerevolution clutch 131, 132, Fig. 4. Eccentrics on a shaft 76 driven by this clutch then act through links 75 and levers 73 to raise the stirrup 49. Associated with each link 36 is a row of ten rods 61 each guided for limited vertical movement and when the stirrup 49 is raised, the end 46 of each link will push upwards that rod of the associated row corresponding to the digit set in that order. The rods 61, Fig. 8, have projections 55SP1/SP in five positions in various combinations and the projections of each row of rods co-operate with five sliding rectangular frames 55 each having a projection 55SP11/SP at its upper end for setting a corresponding pin 58 in the storage device. Thus, as a rod 61 is raised, the corresponding frame or frames 55 will also be raised and will set pins 58 to represent in coded form the digit associated with the rod. Column-spacing storage device A rack 88, Fig. 2, secured to the storage device is engaged by a pinion 89 driven through alternative reverse gearing 92, 91 or 92, 93 and through a friction clutch from the punching-unit motor. Columnar positions are determined by notches in a bar 115, Fig. 7d, secured below the storage device in co-operation with a pawl 117, Fig. 4, pivoted in the fixed frame At the end of a cycle of the accounting-machine, the pawl 117 is withdrawn, to permit a tabulation to the next column, by a rod 123 carried by a lever 125 and depressed by a lever 127 rocked by a stud 133 in the driven member 132 of the onerevolution clutch 131, 132 tripped at this time as described above. The storage device is moved in the return direction on forward movement of a rod 20, Fig. 1, which, under manual or carriage control, produces a power-driven return of the paper carriage of the accounting- machine. The rod 20 is coupled to a link 22 which rocks a lever 142 controlling the reverse gearing 92, 91, 93 for the storage device. When the lever 142 is moved in this way to initiate a return movement, it is latched by a pawl 152 which is tripped by an abutment on the storage device to release the lever 142 at the end of the return movement. The storage device is then driven in the tabulating direction into the first columnar position. Movement of the lever 142 is, however, normally blocked by an arm 193 which is rocked, to permit the lever 142 to cause a return movement, by the engagement with an arm 195 on the same shaft of a control bar 196 on the storage device. The bar 196 is arranged to prevent return of the storage device until it has been fully set prior to the punching operation Operation of the return control link 22 rocks the lever 125 to withdraw the pawl 117 and also the pawl 118 referred to below. Control of zero punching. The plate 211, Fig. 2, on which the ends 45 of the setting links 36 slide, has a cut-out into which the ends 45 drop when in zero position so as to become ineffective when the plate 211 is raised to transfer the setting to the rods 61. However, in order to set zeros in the storage device in those denominations of a column not containing significant figures, so that these zeros will later be punched, the cut-out may be filled by a slide 215 which is moved in to an extent depending on the number of denominations in that column into which entry is being made. For this purpose, the slide 215, Fig. 4, is controlled through levers 214, 121 by a pawl 118 which is moved bodily along by engagement with notches in a bar 116, Fig. 7c, secured below the storage device and related to the bar 115 which controls column spacing. At the end of each entry cycle, the rod 123 which is depressed to withdraw the pawl 117 also rocks the lever 125 and, through a link, a plate 122 which withdraws the pawl 118 irrespective of its longitudinal position. Punching. When the storage device tabulates past the punching position during setting, a roller 156, Fig. 4, in a lever 149 pivoted on an arm 155 drops off a plate 160 secured to the storage device Later, when the setting has been completed, the storage device is returned as described above and the end of the plate 160 strikes the now-lowered roller 156 and rocks the lever 149 which rocks a pawl 163 to release a second one-revolution clutch 165, 166 so as to drive a shaft 105. Eccentrics on this shaft act directly on links pivoted on either side of one end of the guides 86 for the storage device and indirectly on links 112 pivoted on either side of the other end of the guides 86. The latter are guided for vertical movement by two pairs of pins 138 working in slots 206. When the storage device is thus raised, the set-pins 58, Fig 2, therein representing several multi-digit numbers simultaneously actuate corresponding punches 87 so as to perforate a tape fed between guides 97. The punches are guided in plates 98, 99 and co-operate with a punching-plate 96. The parts are secured together by bolts 95 and accurately aligned by rods 94, which also guide a frame 101 carrying the guides 86 for the storage device The frame 101 also co-operates with flats 47 on the punches to restore actuated ones. Small punches 114 actuated by the frame 101 produce transport holes in the tape. At the end of the punching cycle, a roller 170 rocks levers 177, 180 to release a wheel 183 for a cycle of operation. The wheel 183 is geared to a shaft 148 which is driven through a friction clutch and thus released to rotate feed drums 184, 185, Fig. 1, for the tape by an amount sufficient to feed out the punched portion. The drum 184 carries radial pins for engagement in the transport holes of the tape. Correcting setting. Operation of a hand lever 220, Fig. 1, through a linkage including members 221, Fig. 4, 224, 226, 229 and 231 rocks the arm 193 which, as described above, effects a return of the storage device. At the same time, the member 226 holds the arm 155 up to prevent the initiation of a punching operation.
