Abstract: 331,588. Dawson, J. C., Williams, J. C., and Camco (Machinery), Ltd. April 6, 1929. Delivery apparatus.-In machines such as folding-machines in which tapes convey paper or like sheets from one folding section to a succeeding section, the tape-driving mechanism can be arranged so that any desired set of tapes move at reduced speed and cause the sheets delivered thereto to be piled thereon in overlapping formation. The general arrangement described comprises a set of buckling-folders 12, Fig. 1, from which the sheets are conveyed by tapes 15 to a knife-folder 17 imparting a right-angle fold. After leaving the folder 17, the sheet may have imparted to it a parallel fold by a buckling-folder 26, Fig. 4, before being delivered by tapes 21 to a knife-folder 25 operating at right-angles to the blade 17. From the folder 25 the sheet drops on to tapes 28 delivering to a tray 31. The tapes 15 may be driven at normal speed by the engagement of an adjustable gear 58 on the shaft 18<1> of one of the tape rollers with gears 59 driven from the main shaft 52 of the machine. Further, the shaft 22<1> of the tapes 21 also may be run at normal speed by means of a vertical shaft 44 connected by bevel gearing 33, 45 and 46, 50 with the shafts 18<1>, 22<1> respectively. If it is desired to deliver the sheets directly after they have left the folders 12, the tapes 15 are driven at a slow speed and the folded sheets are piled thereon in overlapping relation and deposited in a tray 20. For this purpose, the gear 58 is disconnected from the gears 59 and the drive is obtained from the cam-shaft 52 operating the folding-knives. An axially-adjustable stub-shaft 34 is driven by reduction gearing 35, 51 from the shaft and carries two bevel gears 36, 37 either of which can be caused to engage a bevel-gear 41 on the shaft 22<1>. The shaft 18<1> is then driven from the shaft 22<1> through the medium of the shaft 44. When the sheets are to be delivered from the tapes 21 to a container 27 or 27', the tapes 21 are driven from the shaft 52 at a slow speed as just described, and the gears 33, 45 disengaged so that the tapes 15 are driven at normal speed by the gearing 58, 59. The direction in which the tapes 21 deliver the sheets is determined by which of the gears 36, 37 on the adjustable shaft 34 is engaged with the gear 41 on the shaft 22<1>. If the sheet is to pass through all the folders, the tapes 15, 21 are driven at normal speed from the gearing 59, the shaft 34 being adjusted so that the gear 41 is disengaged from both of the gears 36, 37. The final delivery tapes 28 are driven from the shaft 52 and reduction gearing 35, 51 at a slow speed through intermediate chain-gearing 53 - - 56 and deposit the sheets in a receiver 31. The folding- knives can be rendered inoperative as necessary. The tapes 21 may be guided so as to have an inclined run just beneath the delivery point of the buckling-feeder 26 so as to decrease the distance the sheets have to drop. Also, the buckling-folder 26 may be constructed as described in Specification 330,343, [Class 100 (ii), Printing processes &c.], so that the fold imparted thereby may be reversed if desired.
