Abstract: 308,352. Camco (Machinery), Ltd., (Assignees of Hitchcock, R.). March 22, 1928, [Convention date]. Delivery apparatus.-Paper sheets being delivered from a folding or other machine are directed consecutively along different paths by means controlled by the sheets. As applied to a folding machine in which sets of buckling folders 17, 33, 40, Fig. 1 arranged perpendicularly to one another, are connected by inclined-roller feedtables 10, 26 provided with sheet-separating means as described in Specification 281,599 for forwarding sheets cut into two parts, the sorting and delivery apparatus is mounted in a separate frame 50 attached to the main machine and is driven from the shaft 47 of one of the delivery rollers' 45 of the machine. A fixed guide 58, Fig. 4, directs the sheet from the rollers 45 between rollers 59, 60 driven therefrom through an intermediate loose gear 53, Fig. 1. Beyond the rollers 59, 60 is a deflector 61 pivoted at 62 and operated by the rotation of a mutilated gear 85 connected thereto by a link 88 so as to direct sheets alternately to stacking conveyers 108, 110' running perpendicularly to one another. The means through which the sheet controls the rotation of the gear 85 comprises a crescent-shaped shoe 69 positioned above a steel part of the feed-roller 59, and pivoted at one end of a bell-crank lever 68, the other end of which is slidable along but controlled by stops 73, 75 and a spring 74 on a rod 72 in threaded engagement with a fixed bar 63 so that the pivot of the shoe can be adjusted and also at the same time it is capable of yielding slightly when unusually thick paper is being dealt with. The lever 68 is pivoted at 66 to a bracket 64 adjustably mounted on the bar 63. An upward extension 70 of the shoe 69 is connected by a spring 78 to the bar 63 which tends to hold the shoe in its normal position shown. Pivoted on a stud 79, Fig. 6, fixed to the frame 50, is a bellcrank lever 81, one end of which is bifurcated to engage the extension 70 and the other end of which has a downturned toe 82 adapted to engage one of four pins 83, 83<1>, 84, 84<1> rigidly mounted on the hub of the gear 85, and prevent the rotation thereof by a continuously-driven gear 90 through a friction clutch 92 on the shaft 86 thereof. In operation and with the parts as shown in Fig. 4, the sheet being delivered engages the shoe 69 and swings it about its pivot so that the bellcrank 81 is moved into its dotted position, Fig. 6, and the toe 82 releases the pin 83. The gear 85 is thereupon rotated through the clutch 92 until the pin 84 abuts against the toe. When the sheet leaves the rolls 59, 60, the shoe 69, and therefore the lever 81 and toe 82, are moved by the spring 78 back to their normal position so that the gear 85 is again free to rotate, and this time moves through about 180‹ until the pin 83<1> abuts against the toe 82, the deflector 61 by this movement being shifted so as to deflect the next sheet downwardly past a fixed guide 109 to the conveyer 110, where stops 111, Fig. 1, limit its forward movement. This sheet in its turn moves the shoe 69 so that the deflector 61 is subsequently reset to direct the succeeding sheet to the conveyer 108. After the friction clutch has started the rotation of the gear 85, the teeth on the gear 85 engage with teeth on a gear 102 driven continuously from the gear 90 through a gear 100, so that the gear is driven positively during the turning of the deflector 61. The shaft 99 of the gears 100, 102 is carried at one end of a bellcrank lever 9, Fig. 1, the other end being adjusted by a set-screw 999. The machine is particularly applicable where a number of signatures are printed on one sheet which is afterwards cut into the separate signatures, and may be modified so as to deflect the sheets into any required number of stacks.
