Abstract: 668. Smith, M. W. Jan. 10. Monotype and like machines.-Apparatus for casting or forming single types and setting them up in justified lines. Fig. 1 shows in sectional elevation the part of the machine for forming the types, and Fig. 19 an elevation of the arrangement for setting-up and justifying the types. The matrices or dies D are mounted on the ends of radially-sliding rods L, L', L<2>, L<3>, any one of which may be brought to the casting position M<1> above the mould m by operating a key B, B<1>, &c. The key stems operate levers l, l<1>, &c. connected to the ends of the rods L, L<1>, &c. Radial pivoted arms or levers may be used instead of the sliding rods L, L<1>, &c. The types may be cast by ejecting molten metal by any suitable arrangement into the lower ends of the moulds m in the mouldwheel M ; or they may be formed from cold metal by compression. In the arrangement shown, the wheel M has four moulds and is mounted on the shaft G moved a quarter turn intermittently to bring the moulds into the casting and ejecting positions successively. The mould cavities are adjustable for the various types by means of radial slides R drawn inwardly by springs and moved into the required positions by wedges g<2> operated in one direction by springs and in the other by a rod Q<3> connected to a lever Q<2> operated by a vertically-movable curved plate Q having projections q, q<1>, g<2>, &c. operated by fingers b, b<1>, b', &c. on the key stems. In a modification, the wedges g<2> are raised by a circular cam plate, and their downward movement at the casting point is limited by a projection on each of the slides R engaging a recess in the matrix head D. The wheel M is moved by pins w on the wheel W on the shaft G operated by a pawl v from an eccentric on the driving-shafting T. The mould-wheel is locked during the cast, by a slide engaging recesses in the wheel W. The matrix D is pressed down into the recess at the upper end of the mould cavity by a presser F operated by a lever f, rod e, and an eccentric on the shaft T. The types are ejected vertically from the mould by a sliding pusher, by which they are pushed up into a verticallysliding carrier P, Fig. 9, adapted to receive and grip the types and carry them up singly along a channel N, from which they drop down a chute N' into a sliding stick 2. The types are collected in the stick 2 against a sliding block 4 drawn to the left by a cord 6 and weight, and are pushed along past a pair of spring retainers 9 by a slide 11, 13 operating an inclined projection p<4> on the carrier P. Compressible space types are inserted from a chute N<2>. When a line is collected in the stick 2 an alarm is sounded and the stick is then moved forward (to the right) by a lever 14 and cam &c. As the stick moves forward, the block 4 engages and is stopped by an adjustable abutment 17 and the line is compressed to the required length. The justified line is pushed laterally by a slide into a galley 30 against a sliding block moving between the sides 18, 18<a>, of which 18<a> is adjustable. The slide by which the line is pushed into the galley is operated by a lever arrangement actuated by the stick 2 at the end of its forward movement. Leads may be inserted between the lines from a magazine 26, from which they are released singly by a hinged shutter 27.
