Abstract: 215. Wheatley, W. H., [Scott, W.]. Jan. 4. Collecting-apparatus ; cutting and perforating apparatus; delivery apparatus; rotary machines; folding paper.-Delivery mechanism, more particularly for rotary all-size printing-machines, is arranged with primary and secondary adjustable folding - devices, so that the sheets, of any predetermined size, after being printed are first folded one or more times, or not at all, and also pasted, associated, and slit if desired, and then may pass to the secondary folding-devices to be further folder once or oftener, and delivered in any required form. The sheets pass from the last of any desired number of printing-couples 12, 13, Fig. 1, to a cylinder 16, having adjustable folding- devices such as grippers 19, folding-nippers 24, and creaser blade 26, all mounted so as to be adjustable circumferentially, and also capable of being put out of action altogether, the cams for operating the devices being also adjustable. These devices co-operate with the grippers 35 and the creaser 38, . adjustably supported, on the cylinder 17, to give the sheets one or two folds, or none at all; by increasing the number of folding-cylinders, any number of folds may be given before the sheets are passed on to the collecting- cylinder 18, which may also be provided with grippers 39 and a folding-nipper 40, in connexion with which throw-off fingers 41, 42 are provided, the nippers being adjustably mounted, and the actuating cams being also adjustable to fold any desired size of sheet at any desired point. For transverse pasting, blades 51, 52, 53, fed from ductors 54, 55, are provided, and for longitudinal pasting a ductor-fed roll 56, these devices being placed at any suitable point in the primary or secondary folding-devices. When the cylinder 18 is used for collecting, the cam 57, pivoted at 58, is caused by the cam 59 to move into position to open the nippers 40 or the grippers 39 only once every several revolutions. When the cylinder 18 is not collecting, the cam 57 remains always in its working position. The sheets pass from the cylinder 18, through the longitudinal slitter 3, by which they are slit at any desired part, along a path 66 to a switch 68, by which they are either passed direct to the delivery mechanism 5, or up the sheet path 67 to the secondary folding-devices 4, which are shown in side view in Fig. 1 and of which half are shown in side view in Fig. 9. The secondary folding-devices consist preferably of one or more pairs of folding-rollers 72, 73 with superposed creaser blades 74, forming folding-sets independently and slidably mounted on transverse framework 80, 82 and adjustable by screws 85, 86, simultaneously actuated by gearing from a handle 94. The rollers 72, 73 and the actuating- mechanism of the creaser blades 74 are driven by splined shafts and bevel-wheels. Each set folds one section of the slit sheets at any desired point, the folded products then passing down automatically-adjustable telescopic guides 99 to the transfer rolls 97, 98, where, by means of a movable switch, the sheets are run on together or separately to transverse folding-devices 121, or to longitudinal folding-devious past the roller 113, removable stops being placed in the path of the sheets if it is desired to fold them by the devices 121. Similar stops 126, Fig. 1, allow the sheets to be passed either through the rollers 72, 73 or direct to a delivery device at 127. The sheets, after being folded by rollers 121, may receive an additional fold at 125. Means is provided to put out of action any of the devices which are not required.
