Abstract: 288,589. Canadian American Machinery Co., Ltd., (Assignees of Olson, A., and Tufts, L. R.). April 13, 1927, [Convention date]. Delivery apparatus.-In a buckling-folder machine in which the sheets after receiving parallel folds in one set of folders 28, Fig. 6, are directed either on to a feed table 14 forwarding them into another set of folders 31, or to a delivery device 67, the setting of the directing device causes the actuation of the mechanism to which the sheets are to be directed, and also the disconnection of the alternative mechanism from the drive. The machine is driven from an inclined shaft 36, Fig. 5, which through a gear train 37 - - 40 drives the rollers 24 - - 26 of the first set of folders. Driven also from the gear 39 through intermediate gears 41, 43 is a shaft 44 on which is adjustably pivoted a pair of brackets 45, 46 carrying feed-roller shafts 47, 48 and a guide plate 9. The shafts 47, 48, carrying rubber-surfaced feed-rollers 51, are geared together and driven from the gear 43 through an intermediate gear 50 mounted on a stub shaft 49 also carried by the bracket 45. When the feed-table 14 and the second set of folders 31 are in operation, the brackets are in their lower position, as determined by slots 78 in the brackets and bolts 80 on the framing, the sheets passing from the rollers 25, 26 over the plate 9 between the rollers 51 on to the table 14 where the sheets are directed at right-angles to their former path into the folders 31 by a fixed guide and inclined rollers 15 in the usual way. The gear 50, in this position of the brackets 45, 46, engages a gear 53 on one end of a shaft 22 which through bevel gearing drives a shaft 19 carrying a pulley 18 over which passes a belt 16 driving the rollers 15 of the feedtable. At the opposite end to the gear 53, the shaft 22 is geared to a short shaft which drives the rollers of the second folding set through bevel gearing 58 - - 60. In order to direct the sheets to the delivery device the brackets 45, 46 are raised together with the parts mounted thereon, the gears 50, 53 thus becoming disengaged, so that the shaft 22, the feed-table 14, and folders 31 are rendered inoperative. The delivery device comprises an endless band 67 mounted on rollers 65, 66 journaled in side members 64 of a frame which is supported above the side members 13 of the feed-table 14 by blocks 62 having pins 63 fitting into holes in the members 13 so that the frame is correctly positioned. The roller 65 is driven from the shaft 47 through reduction gearing 72 mounted on one of the side members 64, the speed of the band 67 being such that the sheets delivered thereto overlap one another in close order so that they can be removed in stacks. The shaft of the roller 66 is adjustably mounted, being pressed outwardly by screw-adjusted springs 68 so as to tension the belts 67. The delivery device may be extended by a table 76 having pins 77 fitting into recesses in the side members 64. The folders 28 may be preceded by a similar set of folders from which the sheets are forwarded to the folders 28 over a table 13.
