Abstract: 346,776. Bookbinding - m a chin e s . SCHRAMM, C., 91, Sylvan Avenue, West Hartford, and CLARK, E. W., 8, Nepaug Street, Hartford, both in Connecticut, U.S.A. Jan. 11, 1930, No. 1100. [Class 16.] A casing-in or book-binding machine comprises means for successively feeding fillers to elevating- blades, applying adhesive to the sides of the fillers whilst they are carried upwards on the blades, means for feeding cases into the path of the fillers and folding the cases against the sides of the fillers, and means for removing the cased fillers from the blades. The fillers 25, Figs. 1 and 4, are placed one at a time edgewise on a vertically adjustable bar 26 between laterally adjustable guide-plates 27. The fillers are fed along the bar 26 by a carrier comprising two successively-acting fingers 38, 39, and a pair of clamp-jaws 40, all of which are connected together so as to reciprocate along a pair of shafts 42. The fingers 38, 39 are mounted to oscillate, and the finger 38 turns in behind a filler and pushes it along to the finger 39, which, in turn, pushes the filler into the clamp-jaws 40, by which it is carried on to a saddle 56. The saddle comprises two spaced plates, in front of which is a pointed blade 59, which separates the mid-leaves of the filler, as it moves on to the saddle. The filler is pushed into correct position on the saddle by a header-arm 60, which is rocked towards the saddle from one side, and is then moved against the rear edge of the filler. The cases 68 are stacked in a magazine comprising adjustable corner-posts 69, and the lowest case is engaged and withdrawn by spring catches on a pair of slides 74, by which the case is delivered to a second pair of slides, also provided with spring catches, which deliver it to a position above the saddle. The slides are operated by racks engaging with gears 80, and the spring catches are withdrawn during the return movement of the slides. Should a filler fail to feed, the consequent closing of the clamp-jaws 40 causes the gears driving the slides 74 to be disconnected, so that the feed of the cases is stopped. The slides 74 carry the case beneath creasing-blades 109, Fig. 14, which are vertically adjustable on brackets 110, themselves horizontally adjustable on shafts 111. The side edges of the case are supported by plates 107, and the back by rails 108. An electrically-heated forming-head 114 is then lifted to shape the back and form the creases, after which the case is moved over the saddle. The fillers are lifted. from the saddle and carried up between adhesive-applying devices by blades 123, Fig. 1, on an intermittentlyfed endless chain 124. The chain is fed by two segmental racks 130, 131 engaging pinions, which are connected by ratchet-mechanism to one of the chain-sprockets. The sprocket is connected to its driving-means through a worm and worm wheel, to enable the position of the lifting-blades to be adjusted. As the filler rises from the saddle, it is pressed down on the lifting-blade by a levelling- member. The filler is raised between rolls 172, Fig. 10, by which adhesive is applied. The rolls 172 are supplied with paste by rolls 173 rotating in tanks 174, which are moved towards and away from the filler by levers 178. The rolls are driven by wormgearing, one member of which is arranged to slide on its shaft, in order to permit of the movement of the tank. The rolls are driven from an oscillating segment through ratchet-mechanism, so as to receive an intermittent feed. A short movement in the reverse direction is given to the paste rolls, to cause them to apply an extra amount of paste at the joints of the filler. This is effected by an arrangement of cam-projected pins on the driven member of the ratchet-mechanism, which are engaged by the driving member when near the end of its return or idle stroke. The lifting-blade 123 raises the filler up to the case, which then rises with it, and the sides of the case are folded down against the pasted sides of the filler by wire yokes 226, which are pressed down by springs. As the filler rises farther, the case is pressed against it by spring-pressed rolls 229, carried by slides 231, which are urged towards each other by cam action. The book is lifted from the blade 123 by plates 248 on the slides 231, which, together with the rolls 229, are caused to move vertically. The book is then grasped at the joints by jaws 249, Fig. 1, on a shaft 264, which swing over and drop the book into a delivery shoot 262.
