Abstract: 628,810. Printing-machines. GOSS PRINTING PRESS CO., Ltd., WHITEHEAD, W. A., and LONG, S. W. H. Feb. 28, 1946, No. 6319. [Class 100 (i)] [Also in Groups XXIV and XXXVIII] A delivery mechanism for use with printing. and like machines wherefrom sheet products are delivered in succession to a conveyer through the medium of a rotary delivery fly comprises a second conveyer adapted to be moved, at predetermined intervals, into and out of an operative position wherein it is disposed in the path of products deposited on the first-mentioned conveyer, said second conveyer being driven at a faster speed than the first so that when in its operative position it will accelerate the removal of the deposited batch of products from the latter, and camoperated means, operated in timed relation with said second -conveyer and with the delivery fly, adapted temporarily to interrupt the delivery of products from said fly at such times as the second conveyer is in its operative position. Newspapers are deposited in regular succession by a rotary S-fly 10 on to a conveyer 13 carried on drums 14, 16, 31, the drums 16, 31 being carried on arms 17, 29 fixed to rockshafts 18, 22. A second and more rapidly moving conveyer 19 comprises a plurality of laterally spaced conveyer bands interposed transversely of the mechanism between similar bands of the conveyer 13, and is carried on drums 23, 20, 30, the drums 20, 30 being carried on arms 21, 28 fixed to the shafts 22, 18. When a predetermined number of newspapers, constituting a batch, has been deposited in overlapping relationship on the conveyer 13, the drums 16, 31 are lowered and the drums 30, 20 raised, so as to bring the conveyer 19 into operative position and accelerate the removal of the batch, by rocking the shafts 18, 22 through link and lever mechanism 32, 33, 38, 36 operated by a cam 35 on a shaft 72 rotated in timed relationship with the shaft 51 carrying the fly. The shaft 72 also carries a rotary member to which are pivoted retaining members 40 having fingers 42 which act to retain the newspapers deposited from the fly until the previous batch has been removed and the conveyer 13 returned to operative position, and thereafter to deposit the retained newspapers in correct relationship on the conveyer. The fingers 42 are accelerated to the right, in the conveying direction, on entering and leaving their retaining zone, and to the left while passing through the zone, by means of rollers engaging a stationary cam 46. The batches pass from the conveyer 19 to a main conveyer by which they are carried to a compartmented conveyer or bundling apparatus driven in synchronized relationship with the shafts 51, 72 by means of spur and chain gearing. After the fly has been stopped, the bundling apparatus can be driven by an independent electric motor to dispose of batches left on the conveyers. After such independent operation, the bundling apparatus may be out of synchronization with the depositing means, and correct phase relationship is restored by a mechanical device (see Group XXIV) or by an electrical device (see Group XXXVIII).
