Abstract: 24,922. Taylor, J. J., and Shiley, R. Nov. 16. Folding paper ; feeding sheets.-Fig. 3 sbows a sectional side elevation of a folding-machine specially adapted for folding books. The table or bed 2 is formed with a slot for the operation of the folding - devices and the feed slide 10, which latter reciprocates in guides 9 and a slotted plate 7 bridging the outer end of the slot in the bed 2. The books &c. to be folded are placed in a hopper formed by upright strips 11 adjustably fixed on the plate 7. The front strips are so set that one book may be carried under them by the slide 10, which is stepped to form a recessed or lower front part on which the book is carried forward, the step or shoulder engaging the rear edge of the book. The folding-devices consist of a fixed blade 45, a movable blade 37, and folding-jaws 34, Figs. 3 and 8. The blade 37 is fixed by a clamp 40, 41 in an arm 38 projecting from a rod 16 reciprocated vertically in guides on a hanger 4 depending from the bed 2. The rod 16 is operated by a rod 19 and an eccentric 17 on the driving- shaft 5. A transverse bar 47 fixed to the rod 16 has eyes sliding on vertical pins fixed on the bed 2, and prevents rotatory movement of the rod 16 &c. The jaws 34 are pivoted at 31 in plates or brackets 30 bolted to the upper end of a rod 24 movable vertically in a sleeve 25 which is guided to move vertically upon a plate 26 adjustable on the hanger 4 by screws 4<1>. The upper end of the plate 26 is formed with extensions on which the blade 45 is fixed. The rod 24 is moved vertically by a cam 43, and the tube 25 by a cam 42. The book moved forward by the feed slide is gripped along the fold line between the blades 37, 45, and is then folded over the blade 37 by the jaws 34 as they rise with the rod 24. The blade 37 is then raised and the jaws 34 are closed to press and complete the fold. The upper edge of the blade 45 is grooved longitudinally to hold the book securely during the folding. The jaws 34 are opened by a spring, and are closed at the proper time by the conical upper end of the tube 25 engaging downward projections from the jaws. The folded book &c. is drawn into a receiving - trough 51, through a side opening therein, by an ejector 55 which straddles the blade 37 and has depending end pieces 56 for engaging the book. The ejector is carried by a rod 54 attached to a slide 57 operated by a bell-crank lever 59 having an adjustable pin 62 engaged by a slotted link 63 connected to a projection 64 on the rod 16. The books are moved along the trough 51 against a block 69, Fig. 11, by a sliding pusher 66, and are retained by spring detents 79, 82. The pusher 66 is reciprocated by a rod connected to a lever operated by the rod 16. The books are centered, with respect to the folding blades, by a pair of side pushers 85, Fig. 8, which are pivoted and operated to swing to and from each other. The supports on which they are pivoted are adj ustable. They are operated by levers &c. connected with a lever 90 on which is a spring engaged by a projection 92 on the rod 16. Another projection operates the lever 90 to return the pushers 85 to their outer position. The parts of the machine may be brought to the required positions, when desired, by rotating the shaft 5 by means of a crank handle applied to a pinion in mesh with the gear 100.
