Abstract: 427,438. Delivery mechanism for printing-machines. QUICK, C. G., BALL, D. A., and WHITEHEAD, W. A., 109, Borough Road, London. Jan. 6, 1934, No. 590. [Class 100 (i)] In delivery mechanism for use with means for feeding a succession or stream of products passing from a printing - machine, two flys are arranged in side-by-side relationship about the feeding zone and rotated in opposite directions, the pockets of the flys being in out-of-phase relationship such that a pocket of one fly is first presented to take a product, whereafter a pocket of the other fly is presented to take the next product, and so on, the flys operating to take alternate products. As shown, the two flys 1, 2 are similar and are each provided with two sets of blades which are spaced 180‹ around the hub to provide two pockets. The products are fed to a point midway between the flys by the folding-off rollers 9, 10 of a folding and cutting cylinder 11 of a printing-machine. Two continuously-driven belts or chain conveyers 12, 13, driven in opposite directions, are situated below the flys. Discs 14, 15 are positioned to extend between the arms of the flys, so that as the latter rotate with a product in one of their pockets, the edge of the product is moved into engagement with the corresponding discs and is caused thereby, as the fly continues its rotation, to move out of the pocket and to drop on the corresponding conveyer 12 or 13 which then carries the product towards the side of the machine, the successive products on the conveyers being spread out on the conveyer. In order to enable the products to be counted, the discs 14, 15 are constructed and actuated as described in Specification 424,422 whereby certain products are allowed to travel further with the flys before they are ejected, these products thus lying over the products previously delivered to the corresponding conveyer. Each fly is shown as having recesses for four pockets, but two of them have short arms which only function in conjunction with the inner fixed ends of the blades forming the pockets on the other fly to steady the trailing ends of the products carried by that fly ; if it is desired to deliver all the products to only one side of the machine, then the short arms of the fly to be employed are removed and substituted by the blades taken from the other fly, in which case the products from the folding-off rollers 9, 10 will be taken by one fly only, and delivered to one conveyer belt. The distance between the two flys, and the position of the flys with respect to the path followed by a product issuing from the rollers 9, 10 can be adjusted, since the shafts 7, 8 of the flys are mounted in brackets which can be adjusted by hand-wheels 31, 32, worm or skew gearing, and screw-threaded rods. The drive for the flys, conveyers, and counting- mechanisms is effected in the following manner. A main driving gear-wheel 34 is fast with an internally-toothed wheel 35 in mesh with a pinion 36 which is fast with a worm 37. The worm 37 meshes with a worm-wheel 38 fast on a shaft 39 provided with right and left hand worms 40, 41 meshing with wormwheels fast with the shafts 7, 8 of the flys, so that these flys are rotated in opposite directions. The counting - mechanisms are driven from the shafts 7, 8 as described in Specification 424,422. The conveyers 12, 13 are driven through spur, worm or skew and worm-wheel, and chain gearing from the gearwheel 34.
