Abstract: 2284. Annand, R. C. Feb. 1. Rotary machines; folding paper; delivery apparatus.-Relates to machines for printing papers of various numbers of pages, and to the folding and delivery mechanism. Fig. 1 shows in diagrammatic side elevation a machine having two sets of printing-mechanisms for printing the two webs C, D from the rolls A, B. The lower or main printing-mechanism has its first forme cylinder 1 and impression cylinder 2 arranged with their axes in a horizontal plane, the inking-mechanism 5 being arranged under the cylinder 1. The second pair of cylinders 3, 4 has its axes in a vertical plane, and with the line of contact of the two cylinders in the plane of the axes of the cylinders 1, 2. By this arrangement the paper comes into contact with only a small part of the circumference of the second blanket cylinder 4, and set-off is prevented. The second inking-mechanism 6 is inclined upwardly as shown. The upper printing-mechanism has its cylinders c, d and 12, 16 arranged as shown, and is driven from the lower mechanism at the same or half speed by gears 9, 10. The gear 10 meshes with a loose wheel 11 on the shaft 12 of the second forme cylinder, and may be fixed by a bolt 17 to a larger wheel 13 keyed on the same shaft 12. This fixes the wheel 11 and drives the upper machine at the same speed as the lower one. The wheels 11, 13 gear respectively with loose wheels 14, 15 on the shaft 16 of the second impression cylinder. By removing the bolt 17 to the position 18 so as to fix the wheels 14, 15 together and release the wheel 11, the upper machine is driven at half speed through the train 9, 10, 11, 14, 15, and 13. At the other end the cylinders are geared together to move in unison as usual. The printed web C passes up the tapes 21, 21<a> to drawing-rollers 22, 23, and the web D may be passed uncut, when the upper machine is running at full speed, to the same rollers 22, 23 for cutting and folding &c. with the web C. In this case the cutting-cylinders 7, 8 are put out of operation. When run at half speed, the web D is perforated by the cylinders 7, 8 and run between the tapes 44, and the sheets are broken off by the cylinders 42, 45. The sheets are carried by the tapes 36<a> &c., and associated with the sheets cut from the web C for folding therewith by the longitudinal folder 47. The web or webs passing between the rollers 22, 23 is cut by the cylinders 25, 26, the cylinder 26 having carrying-pins so operated that two sheets may be associated thereon and then passed to the cylinder 27, which also has carrying-pins, or that the sheets may be passed direct to the cylinder 27 at every revolution. The carrying-pins on the cylinders 26, 27 are operated as required by a pivoted cam 30, which may be locked in stationary position, when the cylinder 26 is not used as an associating-cylinder, and may be rocked by a cam 33 when the cylinder 26 is required to act as an associating-cylinder. The bolt or pin 34, which secures the roller operated by the cam 33, is used to lock the cam 30 when the bolt and roller are removed to render the cam 33 inoperative. The tapes 36 which carry the sheets over the diagonal edges or guides of the folder 47 are returned over bent or rounded pieces placed parallel to and a little above the guides or edges of the folder. The method of using the machine for producing papers having various numbers of pages is described. The Provisional Specification indicates that more than two printing-mechanisms may be combined.
