Abstract: 29,398. Lake, H. H., [Goss Printing Press Co.]. Dec. 31. Rotary machines; delivery apparatus; folding paper associating and collecting apparatus; cutting- apparatus. - Multiple perfecting rotary presses, preferably of the type having several sets of mechanism one above the other, are provided with gearing by which either of the sets can be run independently, or they all may operate in synchronism, and also with delivery apparatus having folding, cutting, and associating appliances so arranged that the webs may be associated after the longitudinal folding and before cutting &c., or after the first transverse fold, or at other stages, or not at all, as desired. In the machine described, two independent perfecting printing-sets A, B, Fig. 6, are shown, B being disengagably driven from the main shaft E through spur gearing, and A through bevel gearing and a short vertical shaft, one of the bevel gears being slidable on its shaft. The folding-rollers &c. 8, 8<1> of the upper delivery mechanism may be driven through gearing a<22> a<34> and a<5> ... a<9>, whence bevel and spur gearing (not shown) drive the other parts of the delivery mechanism. In each of the trains of gearing, one of the wheels is made slidable on its spindle, for throwing the mechanism out of gearwith the printing-rollers. The rollers 9, 9<1> of the dower deliveryl mechanism are driven in a similar disengageable manner from the lower printing-press through the gearing b<4> ... b<22>; and the upper delivery mechanism may also be driven from the same source through a disengageable bevel-wheel 19 on the shaft b<18>. The web from the printing- press A passes over the longitudinal folder 6, Fig. 1, between rollers 8, and may then be passed to either side over guide-pulleys, and conducted to join the web from the press B, after it has been longitudinally folded by the folder 7, and as it passes to the rollers 9, or to the associating-drum 12. In this case, the upper web may pass round the rollers 12<1>, 10<1>, 13<1>, 33, 35, 36, 42, and then either over the small tape rollers to rollers 9, or over the drum 10 and guides 17 to rollers 12. The upper cntting-blades on the cylinders 10<1> or 11<1> are in this case removed. If desired, the upper web may be cut and associated before being passed down the tapes as before, or folding-blades may be added to the cylinder 13<1> to fold the sheet transversely between the rollers 13<1> before they pass down the tapes 31, 41. The rollers 36, 42, at the end of swinging arms 40, may be positioned to deliver the sheets either to -the lower folding and associating cylinders 12, 10, to meet the sheets from the lower web, or to the rollers 24, 21, carrying tapes by which the folded sheets from both webs are passed to the rollers 27 and the folding-blade 26 to receive a final fold. The machines may operate quite independently, in which case the switch 8, used to deflect the upper sheets to the lower folding &c. devices, is put out of action, and the upper sheets are then passed between tapes to a final folding- apparatus 26', the lower sheets being folded &c. independently in a similar manner, or otherwise, as desired.
