Abstract: 22,194. Wade, H., (Burroughs Adding Machine Co.). Nov. 7. Adding &c. apparatus; with printing-mechanism; column-spacing; printing totals.-For condensed-record work, adding and listing machines are provided with a tally-roll attachment adapted to be shifted laterally or otherwise into operative position over the main paper-support, which may be fixed or movable for column-spacing. The shift may be effected manually, or automatically, on depression of a key, or as an accompaniment to operation of the machine after setting of a key, or, for column-spacing, in conjunction with the main carriage or on depression of the totals or sub-totals key. Specifications 1810/08, 16,800/08, 712/09, 3516/10, 25,068/11, 25,588/11, 15,107/14, [Class 100 (iv), Typewriters &c.], and 21,275/14 are referred to as examples of machines having suitable paper-carriage constructions, inoluding column-spacing arrangements and means for handling leaves of loose-leaf ledgers. (1) Figs. 13 and 15 show an arrangement in which the tally-roll attachment is shifted manually. Thetally-roll holder or carriage is made of sheet metal and comprises supports for a supply roll 40<a> and a feed-roller 36 connected by a vertical plate 37, which is disposed between the back panel 2 of the machine and the main carriage tracks 20. Thecarriage is secured to a slide-rod 30 taking the place of the hinge-pin in the hinge-lugs 31, 32 of the back panel, and is moved into operative position by means of a hand-lever 91 pivoted on the base of the machine and terminating in a forked end embracing a roller stud 87<a> on the slide-rod. The operative and inoperative positions of the carriage are, determined by stops 85, 81 on the slide-rod contacting with the adjacent lug 31. A spring 80 is provided to return the carriage to the inoperative position. A friction latch 100 is provided to co-operate with two notches in the sliderod and hold the carriage in either position; this latch can be turned into and out of action as required, and serves to render the spring 80 inoperative. (2) For automatic column-spacing, the tally-roll carriage is provided with a tappetblade 130, Fig. 15, and the usual tabulator rockrod 106, Figs. 13 and 15, on the main carriage is provided with the usual stop-fingers 107 extending forwards, and with one or more additional stop-fingers 120, extending downwards to engage the tappet-blade 130 and shift the tally-roll carriage with the main carriage. Two stop-fingers 120 are described, giving two columnar positions for the tally-roll carriage; when the rock-rod 106 is operated, the first finger 120 is swung clear of the tappet-blade, and the main carriage moves on to the second columnar position, carrying with it the tally-roll carriage by means of the second finger 120. In the return movement of the main carriage, the first finger 120 turns aside the tappet-blade, which for this purpose is hinged and spring-retained. (3) The stop-fingers 107, Fig. 13, co-operate as usual with a coupling-pawl 116 for sliding plates 110, 115 terminating in jaws embracing the line-spacing bail 111, and the pawl 116 actuates the rock-rod 106 as usual for automatic column-spacing; for ordinary columnspacing, the shift is entirely manual, and a special key is provided to disable the pawl 116 and throw into action a second coupling-device 145 which does not co-operate with the stop-fingers 107. (4) Fig. 2 shows a modified actuation, in which the spring 40 advances the tally-roll carriage, and the return movement is effected automatically by means of a lever 51 operating against a roller stud 52 on the slide-rod 30. The actuation is controlled by a special " tally " key 73, Fig. 9, connected to a lever 70 returned by a spring 99. The lever 70 lies under the tail 58a of a pawl 58, Fig. 2, which normally couples the lever 51 to a bell-crank lever 57 connected by gearing 55, 56 to the reciprocating line-spacing plate 89. The lever 70 also carries at its end a latch-plate 75, which is guided in a slotted collar 78 attached to the guide-lug 33, so that an horizontal shoulder 75a normally occupies a notch in the upper side of the slide-rod 30 and holds the tally-roll carriage in the inoperative position. When the key 73 is depressed, the latch-plate 75 is withdrawn, and the pawl 58 is tripped to release the lever 51, allowing the carriage to advance to operative position, determined by a stop 80; the key can be held down to maintain the pawl 58 and latchplate 75 inoperative, and when the key is released, the pawl 58 recouples in the last halfcycle of operation of the machine. (5) Fig. 9 also shows connexions from the link 226 of the totals and sub-totals keys for controlling the actuation, in this case the columi-spacing, so that totals are distinguished from items by lateral position. The link 226 is provided with a V-shaped stud 90 for co-operation with a V-shaped end of a lever 91, the lower arm of which terminates in a cam-finger 91<a> for co-operation with a stud 70<c> on the lever 70, giving a lift to the lever 70 less than the normal amount given by the key 73. The latchplate 75 determines the carriage position, a vertical shoulder 75<c> engaging a shoulder formed on the slide-rod 30 by flattening the rear side at the end. The stud 90 first engages the end of the lever 91, to lift the lever 70, and then slips past the lever 91, which is immediately returned by a spring 91<b> and releases the lever 70, and finally, in the return movement of the link 226, the stud 90 returns to the front side of the lever 91, this movement being facilitated by providing a depression 226<a> in the usual slot in the link, and a spring 100 to pull the link downwards.
