Abstract: 16,011. Justice, P. M., [Dougall, J. R.]. July 20. Linotype machines.-The assembler E, Figs. 2, 4, and 7, is mounted in a vertical pivot e for horizontal oscillation, so that the matrices are received and delivered in directions at an angle. The channelled part e' of the assembler is mounted to slide on the lower pivoted part e'. A hand-lever e<3> is jointed to the part e', and is pivoted to the part e<2> and also connected to the part e' by a spring e<4>. The lever e<3> and the assembler are locked in either position by means of a fixed notched plate e<5>, which also serves to hold the parts e', e<3> forward during rotation. The matrices are held in the assembler between spring pawls e<12> and a sliding finger e<6>. The finger e<6> is on a slide e<7>, which is mounted in a groove in the assembler, and acts on a friction slide e<9> through a spring e<8>. This finger slide also serves for ejecting the matrices, by engagement of a toothed spring pawl e<15> with a toothed actuating-bar e<16> linked to a vibrating lever e<18>. The action is moderated by means of a piston and rod e<10> and a dash-pot e". The pawl e<15> is normally held down by a latch e<19>, which is released by means of a finger lever e<20>. The pawl e<15> is disengaged from the bar e<16> by means of an inclined slide e<22>, which is actuated by a finger lever to engage an arm e<21> of the pawl. The pawls e<12> are released by means of sliding pins e<14> adapted to engage the framing. A stop lever e<30> is formed with a shoulder to serve as a stop for the bar e<16> and is also notched at the forward end e<31> to interlock with an arm e<32> on the assembler. A line support G is carried in front of the mould H on a vertical slide provided with a lifting-spring. The matrix line is sustained during delivery by means of a vertically-sliding finger I, Figs. 2 and 19, on the bar e<16>; the finger I is operated by means of a pivoted switch bar on the support G. The mould H, Figs. 2 and 17, is in the usual form of a slotted block, and is mounted on an arm h of a horizontal shaft h<1> adapted to rock and slide endwise. A horizontal shoulder is provided on the mould to overlie the lips or shoulders on the matrices and effect alignment on the rise of the support G, and end lips or shoulders are provided to confine the ends of the matrix line. A justifier bar is carried on a rod j, Fig. 2, actuated by a lever j<1>. The melting-pot K, Figs. 2 and 7, is supported by legs mounted on a horizontal shaft, and is held forward against gravity by a.lever k<2>, which is pivoted to the framing and acts on a spring mounted on an eye-bolt loosely connecting the lever to the pot, and carries an antifriction roller co-operating with a cam k<4> on a shaft k<5>. The plunger k<6> is actuated by a spring-depressed lever k<7> operated by a cam k<9> on the shaft k<5>. The slug is trimmed in the mould type-high by means of a knife S, Fig. 17, adjustably bolted to a framing arm provided with a roller m for contact with the arm h. The slug is delivered by a sliding blade N between adjustable vertical trimming-blades and into a shoot, which is formed with a shoulder or offset, so that the slug is turned over endwise and slides into a galley provided with a sliding support and a vibrating pusher. The matrices and spacers are delivered from the support G, Fig. 7, by means of the finger I, the matrices being transferred to a toothed elevator bar W, Figs. 2 and 19, for delivery to a distributer bar T, and the spacers being transferred to a carrier V for delivery to the space magazine F. The elevator W is guided by a fixed twisted bar w, and descends by gravity, and is raised by a chain w<3>, which is passed over a fixed pulley w<4>, a pulley w<5> on a vibrating arm w<6>, a fixed pulley w<7> and back to the arm w<6>. A roller w<8> on the arm w<6> engages a cam on a shaft x<3>. The carrier V is supported by wrists on two horizontal crank arms v, v<1> carried respectively by a vertical guide rod v<2> and a vertical shaft v<3> mounted to rotate and to slide through guides in the framing. The cranks v, v<1> are connected by a collar and groove and also by pinions v', v<5>. The spacers are retained in the carrier V by means of pivoted pawls v<16>. The shaft v<3> is provided with a grooved collar embraced by a lever v<6> linked to a lever v<8> actuated by a cam on the shaft x<3>, Fig. 27, and a pinion on the shaft v<3> meshes with a spring-returned rack linked to a lever v<14> actuated by another cam on the shaft x<3>. The shaft x<3> is geared to a driving- shaft x, Figs. 27 and 28, provided with a loose driving-pulley X and a clutch comprising shoes controlled by toggle levers x<5> on a rod x' sliding within the shaft. The rod x' is urged inwards by a spring x<6>, and is moved outwards by means of a collar x<7> on a forked lever x<8>. The lever x<8> is connected to a bar x<9> linked to a hand-lever x<10>, Fig. 2, and is also operated automatically by means of a latch x<12> and projections x<13> on a cam on the shaft x<3>. The latch x<12> is released on operating the bar x<9>, which is borne by an arm x<16> on the shaft x<15> carrying another arm x<14> connected to the latch. Another arm x<17> on the shaft x<15> terminates in a stud or pin disposed in the path of the lever e<18>, Figs. 7 and 27, which is urged rearwards by a spring e<25> against the action of a cam e<26> on the shaft x<3>. A latch e<27> on the framing serves to hold the lever e<18> forward and is connected with a sliding rod e<28> extending into the path of the assembler. The lever j<1>, Fig. 2, actuating the justifier bar, is urged upwards by a spring j<2> and operated by a cam on the shaft x<3>. The ejector blade is connected by a rod to a lever n' loose on the shaft k<5>, and a revolving arm on the shaft k<5> carries a pin sliding in the outer angular end of the lever n' and tripped by an incline on the framing. The lever n<1> is spring-returned and is provided with a handle. The shaft k<5> is connected by mitre gear to an intermediate shaft k<10>, which carries a pinion engaging a sector rack on the gear wheel x<2> on the shaft x<3>. The pinion has a square hub co-operating with delay surfaces on the gear wheel. The mould shaft h<1>, Fig. 17, is provided with a crank h<5> connected by a rod h<6> to a crank wheel on the pinion shaft actuated intermittently by a rack on a cam wheel on the shaft x<3>, Fig. 2, and the pinion is provided with a square hub or delay surface corresponding with the cam surface. The shaft h<1> is moved endwise by means of the cam wheel and a rocking-frame. The slide for transferring the matrices from the elevator W, Fig. 2, to the distributer bar T is linked to a lever w<10>, which is attached to a hub mounted on the framing and provided with a second arm w<11> actuated by a cam on the gear wheel x<2>. In order to adjust the machine for lines of different lengths, the bar e<16> is provided with an adjusting-screw for controlling the advance. The machine may be arranged for automatic operation throughout.
