Abstract: 12,118. McClellan, J., McClellan, G. H., McKibbin, G. H., and Everett, B. June 13. Bookbinding.-Leaves of a book to be bound are fed to supports D<7>, Figs. 2 and 3, and lowered between pasting-plates C<7>, and then the back or cover is fed to tables D<2>, the plates C<7> are pressed against the leaves and withdrawn, and the support D<7> moves upwards and carries with it the back or cover, which is pressed down against the gummed outer leaves by hand &c. The machine is driven from a shaft a geared to a shaft a<5> and provided with any suitable clutch mechanism a<6>. The support D<7> moves at one end in a groove in a standard D<9>, and is adjustably secured at the other end to a bar D<4> reciprocated by a circular cam B<4> on the shaft a<5>. Triangular cams B<3> on the shaft a<5> oscillate rods B<5> carrying pins B<9> engaging slotted heads of levers b<2>, both of which have also a segmental head b<4> engaging a wheel b<6> on a shaft b<5> provided with a clutch head b<7>, with which a clutch head C<9> on the hub C<8> of the corresponding pasting-plate C<7> is intermittently engaged by sliding, to give the plate a half-rotation in a paste tub E. The pasting-plates are carried on extensions C<3> of plates C', which are fitted in grooved supports C and linked to arms C<5> of rock-shafts B actuated from grooved cams a<8> on the shaft a<5>. The plates C' also carry the tables D<2>. The tub E is supported on a shaft E' adjusted by means of a lever and secured by a set-screw. Each extension C<3> carries oppositely-projecting arms G<3>, G<4>, at the back of the latter of which is a movable support G<6> connected to a sliding block G<7> provided with a spring tongue G<8> for removing excess of paste from the adjacent plate C'. The block is connected to the extension C<3> by a spring. Each arm G<3>, G<4> carries at its free end a head m for adjustably supporting a scraper m<2>, which extends across the face of the corresponding plate C'. The edges of the leaves are protected from paste by supplemental larger leaves placed detachably within the outer leaves. These supplemental leaves g, Fig. 2, are removed by jaws k<2> of clamps k, only one of which is shown. The clamp is adjustably secured on a cross-bar K carried by a rod h<7> fixed to a wheel h, which is partially rotated by means of links h<2>, h<3>, h<5> from a head on the corresponding arm C<5>, Fig. 3, and returned by the action of a spring h<6>. One of the fingers k' of the jaw k<2> is operated by a stop-pin k<4> to open the jaws, as shown in dotted lines, and, as the clamp moves towards the position shown in full lines, the jaws close on the sheet g, which is carried round and released by the action of a stop-pin k<5>. Means for feeding books and covers are shown in Figs. 8 and 9, omitting most of the parts shown in Figs. 2 and 3. The books 23 to be bound are supported vertically in a gravitating carriage 22, mounted on rollers or wheels 21 on an inclined track 20. A sliding bar 29, mounted in standards 28, is actuated by an arm 18<c> of a lever 18, which is pivoted to an arm 16 secured to the frame 7, connected to the frame by a spring, and provided with a pin engaging a groove in a cam-wheel 9 on a power shaft 8. An arm 31 on the bar 29 is provided with a pivoted pawl, and is adapted to engage the foremost book 23 and transfer it to, and move it along, a blade or support 34 secured to a shaft 11 actuated from an eccentric 10 on the shaft 8 and corresponding to the support D', Figs. 2 and 3. The backs 40 are carried on a table 38 provided with an inclined support 41 and secured to the supported end of the blade 34, and are transferred to movable tables 35 by a suction device comprising a shaft mounted in bearings depending from the table 38 and provided with blocks 45 for tubular arms 47, which are provided with suction caps 48 and connected by flexible tubes 49 to a pump 14 actuated by an arm of the shaft 11. An adjustable bar 37 with an extension 37<a> is secured to the frame and projects parallel to the table 38. An angular arm on one of the blocks 45 carries a roller adapted to move on the part 37<a>, and is connected to a cord 52 carrying a weight 54. A sliding bar 56 is connected to cords 55 carrying weights 59, and provided with rollers bearing on the supports 38 and 41. Springs, not shown, prevent the removal of more than one back at a time. In a modification of the book-feeding device, the carriage is moved intermittently up an inclined track by means of a rack and pinion and a ratchet-wheel operated from the power shaft. A stationary gauge 60 is provided on the support 34, Fig. 9 A modified form of gauge is shown in Fig. 16, and consists of an arm 82 pivoted on an adjustable support 80 and adapted to be struck by a fixed finger 87 and engaged with a spring 85 as the support moves downwards for the pasting-operation, and released by a finger 86 on the upward motion so that it takes up the gauge position shown in dotted lines.
