Abstract: 367,997. Delivery-apparatus for paperfolding machines. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Wood Newspaper Machinery Corporation ; 501, 5th Avenue, New York, U.S.A.) Jan. 17, 1931, No. 1648. [Class 100 (i).] Folding and delivery apparatus for printed products comprises a pair of folding units, delivery apparatus for each folding unit and means whereby the delivery-apparatus of either folder can be reversed so that the products of that folder can be transferred to the delivery of the other folder. Each folding unit, which comprises folding and cutting cylinders 15, 16 respectively, is mounted in a frame 10 consisting of a single casting. The products from each folding cylinder are forwarded by folding rollers 19 to a delivery-fly 32 depositing them on endless tapes 31, those for the two folders normally moving in opposite directions, i.e. when both folders are operative. Driven from the shaft of each folding cylinder 15 through mechanism 20, 21, 22 is a pair of gear wheels 23, 24 and, for normal working, the gear wheels 23 engage gears 25 on the flyshafts 26 and rotate the flys. The shafts 30 of the tape pulleys 72 are driven by gearing 25, 25a, 28b, 29 from the shafts 26. Two sets of bearings 39, 40 are provided for each shaft 26 such that when the shaft is in the bearing 40, the gears 23, 25 interengage, but when the shaft is in the bearing 39, the gear 25 engages the gear 24 and the fly and delivery tapes are driven in the reverse direction. If therefore it is desired to deliver the products from the left-hand unit to the right, Fig. 1, the left-hand shaft 26 with the fly 32 thereon is removed, and the right-hand shaft 26 also is removed and placed in the bearings 39 of the left-hand unit. In order to convey the products from the tapes 3 of the left-hand unit to those of the right-hand unit, intermediate tapes 31<1> are provided which pass over pulleys 73 coupled to the shafts 30 by freewheel mechanism so that during normal working they are not operated, but if either set of tapes 31 is driven in the reverse direction, the tapes 31<1> and the other set of tapes 31 are driven therefrom. In order to provide for the removal of each shaft 26, the lower halves of the bearings 39, 40 are formed on a casting 38, Fig. 8, connected by a pin-and-slot arrangement 44, 45 to a pivoted frame 35 which is held in operative position by fly-nut connection 48, 49 and rests, when lowered, on a cross-bar 33. Inclined rails 46 are provided on the casting 38 on which the shafts 26 can be rolled into or out of the unit. A device is provided for dividing the delivered products into counted batches and comprises the usual pusher-finger 66 pivoted to a frame 51 and operated from a cam disc 55 through levers 57 .. 63. The disc 55 is loose on the shaft 26 and is driven by gearing 27, 28 from a shaft 28a carrying the gear 28b. The frame 51 carrying the counting apparatus is pivoted on the shaft 26 and has a hooked end 52 which is engaged with the crossbar 33 when the frame 35 is raised so as to keep the frames in place.
