Abstract: 434,503. Sheet delivery apparatus. QUICK, C. G., BALL, D. A., and WHITEHEAD, W. A., 109, Borough Road, London. April 19, 1934, No. 11852. [Class 100 (i)] A mechanism for delivering the products from a printing- machine in counted batches comprises two delivery flys 1, 3 arranged side by side, the flys being rotated in opposite directions and receiving products directed thereto by a switch operated periodically to cause a number of products to pass successively to each fly, each fly delivering its products against a stop associated with a respective tray from which they are removed by a conveyer in such a way that the products from one tray are superposed on those from the other tray. The products from the machine are folded off by rollers 7, 8 beneath, which is the switch device comprising arms 12, 13 rocked by a parallel-motion linkage from a lever 17 secured to a hub 32 rotatable on the shaft 5 of the fly 1. Pivoted to the hub 32 is a lever 28 carrying a roller 27 movable in a radial slot 29 in a fixed bracket 30 and controlled by a cam groove 26 in a disc 24 also rotatable on the shaft 5. The disc 24 on its other face is formed with radial grooves 25 engageable by rollers 23 secured to a gearwheel 20 rotatable by a gear-wheel secured to the shaft 5. To ensure that the disc 24 is stopped in the correct position, a flange 48 on the wheel is formed with openings corresponding with the positions of the grooves 25, the openings being engaged during the periods of rest of the disc by a roller 40 which is adapted to be disengaged just prior to the entrance of one of the rollers 23 into a groove 25. The flys deliver their products with the folded edges oppositely directed into trays formed by spaced members 51, 54 respectively, stops 53, 55 acting to cause correct delivery. The tray formed by the members 54 is arranged at a higher level than that formed by the members 51, and the trays may be movable towards and from the flys so that the distance through which the products fall is maintained constant. Beneath the trays is a conveyer formed by endless chains carrying fingers 57 which pass between the members 51, 54 and carry the products forward to the delivery point, the chains being provided with sectional shaped supports 67 for the products. The fingers are pivotally mounted on the chains and are provided with rollers 59 engaging a cam track 61 which prevents the fingers from turning due to the propulsion of the products. At the end of the track 61, the fingers are allowed to turn, and rollers 60 thereon engage a cam track 62 to hold the fingers in folded condition, the cam track being shaped at 63 to turn the fingers into operative position again. In order to prevent damage, the posts 56 carrying the members 54 are free to turn against the action of springs to enable an obstruction to be cleared, and arms 65 are adapted to be depressed by projections on the chains and to be raised by springs 66 when a bundle of products has passed to sweep any obstruction off the chains before the fingers 57 are moved downwardly.
