Abstract: 25,291. Thompson, W, P., [Lewis, W. I.]. Nov. 21. Glueing.-A machine for attaching fly-leaves, cuts, engravings, &c. to signatures may operate automatically throughout, or the work may be fed and removed and papers folded by hand. Two or more signatures at a time may be acted on by the duplication of various parts of the machine, and if the head-end-registering mechanism is fixed in reversed position, back and front end-papers may be attached to separate piles of signatures at one time. Signatures x piled in the magazine c with their folded edges forward are fed automatically by suction cups d and nippers f, f The suction cup d is carried on a lever d<1> driven from a cam on an auxiliary shaft 1 geared to the main shaft b. Air is exhausted by the pump d<9>, which is operated through levers d<10>, d<11>, driven from a cam on a second auxiliary shaft 4, and by the spring d<15>. Separating-blades e are introduced between the bottom signature and the remainder of the pile by a set of levers operated by a cam on the shaft 4, and lift the pile to allow the nippers f, f to grip the lowest one. The jaw f is fixed to the movable frame g; the jaw f is fixed to the spindle f<2>, sliding in the rocker f<3> and carrying collars f<5>. The jaws are opened and closed by the rocker f<3> engaging these collars, the closing being effected through a spring f thus allowing for variable thickness in the signatures. The rocker f<3> is actuated through levers f<61>, f<9>, f<10> from a cam on the shaft 4. The signature is gripped by the jaws f, f<1>, and is carried forward and dropped on to an inclined table h which may have travelling tapes to feed the signature up to the stop-pins i on the bar i<1>. Glue or other cementitious material is applied to its edge by a dabbing-strip k, mounted on a shaft k<1> which carries a crank k<2> connected by a pin joint to a link k<4> pivoted to the machine frame. The gear wheel k<7> is fast on the shaft k, and the link k<12>, which is loose on both shafts, causes it to engage the loose pinion k<8> on the shaft m of the glueing-roller m<1>, which runs in a vessel of glue. The pinion m is driven from the shaft 1 by a chain k<1> running on a sprocket-wheel k<9>. The roller m<1> is geared to the shaft k<1> by toothed gear (not shown). The edge of the pad k is thus moved in a vertical arc between the roller m<1> and the signature, which it presses, while glueing, against the bar i<1>, which is rocked about the pivot i<3> by a rod i<6> operated by the spring i<x> and a cam on the shaft 1. To prevent the signature from sticking to the pad k, the clamping-bar p is lowered against the action of the spring p<2> by the bar i<1> to hold the signature against the table h, which is thus slightly depressed. Guides p<3> prevent the signature from riding over the bar p. The bar i<1> is next slightly lifted to permit the table h and the signature to rise clear of the table o<2>, to which the fly-leaf is passed from the rear table o<10> along the feed-tapes o, being folded by the bar p<4> on the way. The lifting of the glued signature permits the fly-leaf to pass up to the guides i without touching the glued surface. The feed-gauge o<11> and presser-roll o<18> are operated from the bell crank o<15> and a cam on the shaft 4, the fly-leaf passes up to the stop o<25>, and the arm p<4> folds it between the rollers o<5>, o<6>. The guiderolls over which the tapes run may be chain-geared. Head-end register is obtained by the side-jog mechanism shown in Figs. 5 and 8. The plate q is movable sideways with the spindle q<1>, which carries a collar q<8> engaging with a forked lever q<5> the lower end of which is moved by a cam q<11> at the end of a crank q<12> on the shaft g', sn that at each movement of the frame g the plate q is moved and brings the signature and end-paper into exact register. The bar p is then forced down and the glued signature thus lowered on to the fly-leaf by a projection on the frame g engaging the bar p. A pair of nippers s, s<1> similar to the nippers f, f<1> seize the signature and end-paper, press them together, and withdraw them from the table h, the pins i being moved out of their path. The signature is discharged from the nippers s, s' by wires t<1> on a rock-sbaft t, pushing it out when the arm t<2> on the rock-shaft engages the fixed cam-piece t<3>. If desired, the glue &c. may be applied directly to the fly-leaf instead of to the signature.
