Abstract: 349,578. Delivery apparatus for printing &c. machines. WINKLER, A. and DœNNEBIER, M., Neuwied, Germany. Feb. 27, 1930, No. 6570. Convention date, Nov. 2, 1929. [Class 100 (i).] The products from printing, newspaper-stuffing, and similar machines are delivered to a pile table 22 from which, after a predetermined and variable number have been collected, they are conveyed to a table where they are added to the previously collected batches in a different angular position to the adjacent batches. Drop-rollers 11 operated in time with the operations of a newspaper-stuffing machine 1 by a cam 15, Fig. 1, on a shaft 4 driven from a shaft 5 co-operate with discs 10 on the shaft 4 to deliver each product on to the table 22 against fixed stops 21. Fingers 24, 25 carried at their upper ends on shafts 26, 27 respectively are oscillated from a cam 28 on the shaft 4 through mechanism 29 .. 32 and cooperate with fixed stops 23 so as to form the pile correctly. After a predetermined number of products have been delivered, the table 22 is moved along guides 48 transversely to the direction of delivery of the products thereto and deposits the batch on rollers 69, 70 which convey it to a table 76. The mechanism controlling the movement of the table 22 comprises a ratchet-wheel 39 aid pawl 38, the pawl being pivoted on a two - armed lever 36 freely rotatable on the shaft 35 of the wheel 39 and oscillated once for each revolution of the shaft 4 by a cam 33. Fingers 41 pivoted at 40 and having lower extensions 43 extend between the drop-rollers 11 and the discs 10 and prevent operation of the wheel 39 unless a product is delivered by engagement of the extensions 43 with a tail part 38<1> cn the pawl 38 so as to lift the pawl from the wheel 39. An annular ring 58 fixed to the disc 39 has recesses 59 therein the distances between which determine the number of sheets to each hatch, so that variation of the number is obtained by securing filling members in some of the recesses. A roller 64, Fig. 2, on a spring-controlled lever 66, runs on the ring 58 and drops into the recesses 59. A link 67 connects the lower end of the lever 66 to a segmental member 68 freely mounted on a shaft 50. Fixed to the shaft 50 is a lever 49- forked to engage a cross-member 46 on the table 22 -and also a segmental member 56 having on its periphery a recess 55 which is shielded by the member 68 when the roller 54 is not in one of the recesses 59. A lever 54 freely mounted on the shaft 50 and oscillated from the shaft 5 of the roller 69 through link mechanism 51, 52 carries a hook-shaped pawl 53 which normally rides over the peripheries of the members 56, 68. When the roller 64 drops into a recess 59, the member 68 noves so as to allow the pawl 53 to drop into the recess 55 so as to impart one to-and-fro movement to the lever 49, and therefore the table 22. An arm 80 fixed to and extending downwardly from the shaft 50 is caused by the oscillation of the shaft 50 and through link-and-lever mechanism 81 .. 92 to throw into operation a one-revolution clutch 93 whereby a shaft 94 is coupled to mechanism driving it from the shaft 5. A toothed sector 101 is oscillated from the shaft 94 through a crank 98 and connecting-rod 99 so as to drive a toothed wheel 103 having coaxial therewith another toothed wheel engaging a rack formed on a vertically-slidable circular bar 78 to which the table 76 is secured. A vertical reciprocation is thus imparted to the table 76 so as to lift the batch s, Fig. 4, delivered thereto and add it to the stack S containing the previously collected batches. Plates 79, 79<1> support the pile S and are slotted at 106 so as to allow corresponding projecting parts on the table 76 to pass therethrough. When the uppermost product of the batch s is just below the stack S the plates 79, 791 are moved away from beneath the stack and the table 76 carries the combined stack upwardly beyond the plates 79, 79<1> which are then caused to return to their original position so that as the table 76 falls, the stack is left supported by the plates. Levers 104, 104<1> carry the plates 79, 791 and are operated from a cam 113 on a shaft 108 driven from the shaft 94 so as to move the plates 79, 79<1> as described above. The cam 113 is adjustable so as to vary the timing of the outward movement of the plates 79, 791 according to the height of the batch s. The table 76 is rotated through 180‹ between alternate reciprocations so that alternate batches in the stack S have their folded edges pointing in opposite directions. For this purpose a curved guide 120 rotatable on the bar 78 is provided, and a roller 123 on the bar 78 is adapted to ride thereon. As shown in Fig. 2, the next two succeeding reciprocations of the bar 78 cause it to be turned through 180‹ during the first reciprocation and to remain stationary angularly during the next reciprocation. In order that the bar 78 may be turned through 180‹ during the next reciprocation it is necessary that the guide 120 should previously be rotated through 180‹ so that the guide and roller 123 are again in the relative positions shown. For this purpose a gear wheel 124 on the shaft 94 having teeth only over half its circumference drives a gear wheel 125 having a pin 127<1> operating a Geneva stop motion 129 geared to a toothed wheel 121 fixed to the guide 120.
