Abstract: 9489. Smith, C. B., Harris, C. J., Zwicker, T. B. G., and Tod, A. April 25. Cutting and perforating apparatus ; delivery apparatus; folding paper; inking-apparatus; paging and numbering apparatus; rotary machines.-Relates to a machine for printing, perforating, consecutively numbering, character marking, and numbering, tab-cutting, tab-numbering or colouring, triple longitudinal folding and cutting a continuous web of paper, more particularly to make counter sale check books of the form described in Specification No. 9488, A.D. 1904, [Abridgment Class Books]. The web of paper Q is first printed on opposite sides by the forme cylinders C, C<1> and their respective impression cylinders B, B<1>, shown in side elevation in Fig. 1, and in end elevation, with the cylinders at the back, in - Fig. 3. If the machine is for printing a book 8 inches long, the rollers C, C' may be 24 inches in circumference, and a ring C<2> on the lower cylinder prints the odd numbers 1 tb 49 on the centre of the web Q once in every 8 inches, the numbers being repeated three times round the cylinder. A similar ring on the upper cylinder C may print the even numbers 2 to 50 similarly on the other side. The cylinders C, C' are adjustably mounted on the framework, and inked from troughs E through messenger and distributer rollers in the usual manner, the whole machine being driven by spur gearing from the driving-shaft A. The paper then passes over a support or roller R, to three numbering-discs S', 25 inches in diameter, running at the same peripheral speed as the paper, and provided with the even numbers 50 to 2 or odd ones 49 to 1, in such an order that each 8 inch length of paper, being pressed against the disc by one of the tappet-arms T<2>, has impressed on it a number two less than the preceding 8 inch length, the numbers being repeated over and over again. The discs are so placed that two mark a duplicate sheet and stub with an even number, while the other invoice in the same row is printed by the third with the next lowest odd number. A second set of discs S' number the upper surface in corresponding fashion, and the second shaft S has also a three-armed casting T<3> carrying three rubber printing surfaces t, opposed by a plain disc T', which print a coloured mark on the paper once every 8 <1>/3 inches, opposite to a number printed by the disc C<2>, this marking taking the place of centre-numbering, such as that by the disc C<2>, on one or both sides. Inking-mechanisms with rollers U, U<1>, U<2> are provided for each set of discs, the rollers U<2> receiving a lateral motion through arms U<3> worked by worm-wheels U<4>. The paper next passes two rollers V, V<4>, the roller V having a V-shaped or other suitable knife or " tab cutter," and the roller V<4> having an adjustable band of soft metal to act as a die. They form an angular cut every 8<1>/3 inches, partly enclosing one of the numbers printed by the ring C<2>, and also cutting out part of the mark formed by the surfaces t. The uncut base of the angle lies along the centre line of the paper, and when this is subsequently folded along this line, the " tabs " project. As the books are cut to 8 inches long, and the tabs are cut every 8<1>/3 inches, a pile of 25 double invoices with their duplicates will have a continuous stepped row of " tabs" " projecting at the back. The machine could also be arranged so that tabs are marked and cut every 7<2>/3 inches, in which case all the previous numberings would have to increase by 2 each marking, instead of decreasing. The web then passes to numbering-apparatus on the shafts W, Fig. 5. A pin a on the frame engages with a star-wheel B<3>, and through gearing revolves the units discs on the shafts D<1> <1>/10th of a revolution at every 25 revolutions of the apparatus, which is fixed between spur-discs A<2>, and turns on the shaft W. Thus, the first two sets of 50 sheets and duplicates are marked A01, the next two sets A02, and so on, up to K99, or as desired, tappet and spur gear being provided to actuate the tens and the letter' discs. The perforating-discs Y, Y', Fig. 1, to which the web next passes, are driven in phase by spur gearing, and can be adjusted on the shafts. The central perforator is cut away for <1>/25th of its circumference, so that it does not perforate along the base of the before-mentioned tabs. The web now passes to a folder consisting of plates a<1>, a<3>, Figs. 1 and 3, having adjustable devices at the upper end by which the edges of the web are folded, one above and one below the central portion, and having also friction wheels b, b<1>, to feed the web, and a pointed adjustable lower end by which the web is finally folded down the middle, the tabs, however, not being folded down. The cutters e<1>, Fig. 3, of any suitable description, cut the web into short lengths, each length consisting of two invoices and duplicates, properly folded. They are delivered by fastmoving rollers f, f <1> to endless travelling tapes on other delivery devices.
