Abstract: 16,266. Richards, B. G. July 15. Delivery apparatus.- A stacking machine for use more particularly with book and like assembling-machines such as are described in Specification 16,210/13, has the following features-(1) means, preferably comprising downwardly projecting members 21 on travelling chains 11 co-operating with upwardly-projecting members 10 on a conveyer 7, to push the books &c. along a slotted inclined table 3; (2) means, such as trapdoors 22, for permitting the articles to fall through the table 1, which forms an extension of the table 3; and (3) automatic means for tripping and resetting the doors. The books drop on to a catching- member or hopper 39 which is rotated through half a revolution between the dropping of one book and the next, to reverse the position of every other book. Means such as trap-doors 40 are also provided in the hopper 39, and have tripping and resetting means to allow the books to drop into one of a series of receivers 129 mounted on an intermittently rotating table 105. The chains 11 and 7 are suitably geared together and positively driven. Guides 12 and supporting-rollers 13 are provided for the chains 11, the links of which carry at suitable intervals supporting-lugs 17 and adjustable transverse bars 19, on which the fingers 21 are mounted. Between the fingers 21 are adjustable pins 36 so positioned that, when a book is situated above the trap-doors 22, pivoted at 23, a finger 36 acts on a trip-lever 33, and, by means of a rod 32, releases spring catches 27 which allow the doors 22 to drop. When the book has dropped, an adjustable finger 74 mounted on a shaft 77, and moved into the path of the fingers 21 by the dropping of the doors, is engaged by one of these fingers and, through lever devices, closes the doors 22 again. The hopper 39 is carried by a gear 41 running on a ball bearing 46 and rotated through half a revolution at intervals by a clutch-operated pinion 52. The clutch 54 is operated through levers from an adjustable finger 65 projecting into the path of the pins 68, 68<1>, which operate the finger 65 to keep the clutch 54 in engagement sufficiently long to give the wheel 41 enough impetus to carry it around until the spring catches 71 again engage the notches 70 and hold the hopper in reversed position. The pins 68, 68<1> are only on every other bar 19, so that only every other book is reversed. The trap-doors 40 are released by catches 90, which are released through lever-mechanism operated from the finger 74 and shaft 77 at the same time as the doors 22 are closed. The receivers 129, into which the books are dropped, have notches or gaps 130 into which a hand may be passed for removing the pile of books. At the front end of the receivers 129 are adjustable angle-irons 120 forming guides for the book edges. The angle-irons 121 at the rear end of the receivers are also adjustable, but have the rear portion 122 pivoted and spring held to permit of easy removal of the pile. At suitable intervals, the table 105 is rotated through a quarter of a revolution by a gear 106, loose on the shaft 49 and driven through a clutch operated by levers from a finger 114 so positioned as only to engage with the pins 68<1>, which are longer than the pins 68. The table 105 is mounted on ball bearings, and is held in position by adjustably spring-pressed rollers 117 engaging notches 116.
