Abstract: 988. Harrison, G., [Smyth Manufacturing Co.]. Jan. 14. Bookbinding.-The casing-in or bookbinding machine shown in vertical sections in Figs. 3 and 5 has a vertically-reciprocating book-supporting plate, two horizontally-reciprocating paste-boxes with rotary rolls which apply an extra quantity of paste near the joints of the book, an adjustable magazine and pushers for supplying cases, and adjustable stretching, jointing, folding, and clamping mechanisms. The supporting-plate 21 is provided with adjustable gauge fingers 22 and is guided by yielding pins 24 and adjustably held on an arm 20 of a carriage 19, which is connected by a link 18 to a lever 16 oscillated by a cam 15 on a shaft 14. This shaft is connected to the driving- shaft 1 by a clutch 4 operated by a treadle lever 8. A rib 25, Figs. 5 and 14, of the carriage, extends into openings in links 26 of two chains 27 passing round sprocket-wheels 28 and idlers 30 on arms 31 projecting from boxes 32 movable with the pasteboxes 52. Each wheel 28 is secured to a driving- part 29 of a clutch, and a groove in the driven part 35 is engaged by a friction pawl-block 37 on a pivoted pawl-plate 36, which is held normally eccentric by a spring and is reversed by means of spring wedges 42 on the links 26. Loose dowel pins 44 can be projected by means of a disc 45 and a handle into the gear 48 on the hub of a paste-distributing roll 50, meshing with gear on the paste-applying roll. The applying-rolls are turned backwards during the operation of the wedges 42 to coat a portion of their peripheries with an extra quantity of paste, determined by gauge plates. The paste-boxes are engaged by studs connected by links to arms on geared shafts, one of which has an adjustable rocker-arm adjustably linked to a lever oscillated by the cam 15. Flanges 53 of the paste-boxes fit loosely in grooves in the framing. A shaft 78, Fig. 3, is connected by gear 76 and a clutch 79, operated by a handle, to a pinion 74 engaging a rack 73 connected to a lever oscillated from the shaft 14. Gears, splined on the shaft 78, mesh with racks 83 on sliding-bars 86 supported by adjustable bars 88. Fingers, movably held in grooves in the bars 86, are adapted to engage the back edge of the lowest case of a pile placed between the bars 86. Nuts on the ends of the bars 88 engage right and left hand screws 92 provided with mitre gears 93 meshing with gears 94 on a shaft 95, one end of which is squared to receive a wrench. A shaft 109, Figs. 3 and 5, on the carriage 19 has a pinion 108 engaging a sliding- rack 107 provided with stud rolls 98, between which and rocker-arms on a vertical shaft, extends a rod. One of the rocker-arms is linked to a lever oscillated from the shaft 14. Cranks 110 on the shaft 109 are linked to slide bars 112 adjustably connected by a crosshead 113 carrying stretching, jointing, folding, and clamping mechanisms. A lever 115 oscillated from the gear 13 is attached to a rack 116 engaging a pinion 117 on a vertical shaft 118 provided with arms 119 connected by a rod 120. A lever 121 loosely engages the rod 120, and is connected by a spring link to a rack 123 engaging a segment 125 adjustably attached to a shaft 126, which has two pinions 129, each engaging racks 130, 131 supporting bars 132, 133 carrying studs with bars 135 and jaws 136. The bars 135 are normally held from the bars 132, 133 by springs. Levers 138, pivoted on the bars 135, are connected by rods adapted to swing and close the case against the book links 140 connecting each end of each bar 132, 133 with the adjacent lever 138. Nuts 142 on screws 143 project into recesses in the bars 112, and the screws have mitre gears 144 meshing with gears 145 on a shaft 146 squared to receive a wrench.
