Abstract: 374. Nind, F. G., and Julyan, F. Jan. 7, 1909, [Convention date]. Feeding sheets etc.; delivery apparatus.-A folding - machine more especially adapted for folding small-sheets of paper with one transverse fold to be followed by two folds at rightangles to the first fold is constructed with a buckling - roller carried in a reciprocating frame, and this roller separates a sheet from a pile and in conjunction with a second roller produces the first fold. The machine is of the kind described in Specification 6518/07. The pile is adjustable in height, and the sheets are supported on their edges and are pressed forwards by a spring- controlled follower-plate which is adjustable vertically and about three axes at rightangles to each other, so that sheets of varying stiffness, thickness, size, and weight c a n be readily folded. As shown, the pile of sheets is pressed by a followerplate 25, carried by a spring - controlled carriage 24, against vertical bars 75, 76, Fig. 10, and the sheets rest on supports 77, which are vertically adjustable by means of pinions 81 in blocks 78 embracing the bars 75, which are formed with racks to engage the pinions 81. The pinions are actuated by a handle 82 and a rod 80, and the bars 77 are locked in adjusted position by screws 83, which engage recesses in bosses on the handles 82. The follower-plate 25 is supported in a manner to allow vertical adjustment by a rod 66 provided with an adjustable collar 73, which rests on one collar 67 and is guided by a second collar 68 on a plate 69, Figs. 9, 10, and 11, pivoted to a plate 59 pivoted to the carriage 24. The plate 25 is adjustable about its vertical axis 66 by means of screws 74, and about an horizontal pin 61 on which the plate 59 is pivoted. The pin 61 passes through arms 57, 58 depending from the carriage 24, the arm 58 being formed with a hole to receive a screw 64 with a nut 65, which locks the plate 59 in its adjusted position. The plate 25 is also adjustable about the horizontal pivot connecting the plates 59, 69, this pivot being perpendicular to the pin 61. The plate 69 is secured in this adjusted position by means of two screws 72, which pass through slots in the heads 70 of the plate 69. The first fold is produced by a buckler roll 30 formed of a number of sections of yielding material, some of which are fluted, arranged on a shaft of square section which is adjustably secured by set-screws 40, Fig. 11, to a rocking frame 36. The frame 36 is oscillated to cause the roll 30 to separate a sheet from the pile, buckle it, and fold it with the aid of a positively-driven roll 31, which is in gear with the roll 30. The frame is oscillated by the action of an adjustable screw 54 carried by an arm 52 on a shaft 51, which is oscillated by a cam 46 acting on a block 47 adjustably secured to a block 48 on the shaft 51. The screw 54 acts on an arm 56 depending from the frame 36, a wear-taking pivoted plate 55 transmitting the motion. The folded sheet is guided from the final folding rolls 89, 90 by star wheels 156, Fig. 4, adjustable to a slight extent, and guides 147 direct the sheets to a delivery table formed of arms 148 connected by a cross-bar 149 adjustably fixed by a bolt 151 and thumb nut 152 to a vertical hanger 150. The wheels 156 engage the ends of the folded sheet and push it forward, and a guard strip 154 prevents the sheets from moving off at the inner sides of the arms 148. The guide arms 147 are attached to the rear of the arms which carry the blade 132.
