Abstract: 19,360. Church, W. H. Aug. 28. Bending; shearing.-A machine for manufacturing shoe, corset, or similar lacings, and for automatically applying metal tips to the same, is shown in plan in Fig. 1, and in elevation in Fig. 2. A belt on a loose pulley b<1> drives a shaft 31, which through pinions b<4>, b<5> drives a cam shaft 32. Through slip-pinions b<6>, b<7> an intermittent motion equal to one-third of a revolution of the shaft 32 is given to a centre cam shaft 33. A cam shaft 34 is driven from a shaft 31 through bevel-gearing s<1>, s<2>, 8<4>, s<5>. The machine is started by a clutch b<2> connecting the pulley b<1> to the shaft 31 ; the clutch is operated by a lever c, Fig. 13, which turns a spindle c<1> against the action of a spring c<2>, a vertical forked arm c' on the spindle c<1> operating the clutch. The lacing-material t is fed from a can x through the slot d<6> in a bell-crank lever d, the end d<5> of which, when a knot occurs in the material t, operates a latch d' to release the lever c, allowing the spring c' to disconnect the clutch b<2> and stop the machine. The material is fed through a tension guide l<4> by a lacing-clamp carrier e<5>, travelling on guides e<3>, e<4> and operated by an endless chain e' on sprocket-wheels e<2>, e<2> driven from the shaft 32 through bevel -wheels f<5>, f<4> and pinions f<2>, f<3>. The clamp e<5>, Fig. 23, is connected to the chain e<1> and has jaws e<7>; e<8> to grip the lace, the jaw e<8> being slidable. The jaws are held in the clamping position by a spring, and are opened by the engagement of a roller e<11> with cam-surfaces e<6>, e<12> on the guide e<3>. The tension guide l<4> is reciprocated twice for each revolution of the shaft 31 to place the material t, first in the lacing carrier e<5>, next in the tip-forming mechanism g, and then in the tip-cutting mechanism m. While the tip is being applied, a reciprocating transverse lacing-carrier device k and the tension guide l<4> hold the lace, the jaws of the carrier e<5> having been released by the cam e<l2>. The lace is then moved into the tip-cutting mechanism m; and fingers of three stretch-eliminating devices n seize the lace. hold it till the tip is cut, and drop it on to one of the four arms of a rotatable lacing-receiver p, the lace being forced from the fingers by a forked rod o. When an arm has received a gross of laces, the receiver is given one-quarter of a turn, to bring an empty arm into position, by mechanism r operated from the lower cam shaft 34. The tipforming mechanism g, Figs. 11 and 24, comprises a plunger g<2> operated by a lever h<1> through a cam h<4> on the shaft 31. A strip of tip-stock v of double width is fed from a reel w between rollers to the dies, where it is first indented by a reciprocating die g<14>. A die g<8> on the plunger has a projecting end g<9> and a semicircular recess ending in a cutting- edge g<11>. The end g<9> bends the strip v into the semicircular recess g<7> in a fixed lower die g<5>, and; when the recesses g<10>, g<7> coincide, a double tip is cut off and folded round the lace. The tip is then cut in the middle by a fixed cutting-blade m<2> Fig. 11, and a vertical reciprocating blade m<3>. The blade m<3> is reciprocated by a connecting-rod m<4> on an eccentric ,disk m<6> driven through gearing from the shaft 34.
