Abstract: 6331. Lanston Monotype Corporation, and Pierpont, F. H. March 14. Single-type composing and casting machines; type-setting machines.-In type-casting or typesetting machines of the kind provided with a die-case, matrix-carrier, or magazine adjustable in two directions for character selection, the capacity of the machine is increased without any increase, or only a small increase in the number of parts of the selecting and positioning mechanism, by the addition to the die-case, matrix-carrier, or magazine of one or more sections, in one or both directions, repeating a part or the whole of the matrices or types in different styles, and the provision of mechanism, controlled for example from a pattern or record strip, for rendering any one of these sections subject to the control of the selecting and positioning mechanism. These sections may be detachable. Fig. 1 shows die-case mechanism of the kind described in Specification 8633/99, provided with the usual gauge pins H, H<1>, stops D, E, and positioning-mechanisms F, G, but having an additional die-case section A' duplicating part of the main die-case A and selected bv an extra stop D' adjusted alternately with the stop D for engagement by the usual secondary jaws F<5>, F‹ of the positioning- mechanism F. The shift signal comprises two perforations controlling ports j<7>, j<10>, and is presented either with the justification-space signal, or in conjunction with a justification signal at the beginning of a line, in which case, as the pump is thrown out of action, a space is not cast. The justification-space matrix is repeated in the added section, and again in the part of the die-case not duplicated, and the space is cast from either of the two extra matrices according to the position in the diecase of the character corresponding to the signal preceding the shift signal. The stops D, D' are pivoted on the die-case slide C, and are forced alternately into operative position, against the action of returning-springs D<2>, by means of a pivoted latch M oscillated against the action of a returning-spring m<3> by a bail L, which, when rocked, engages a tail-piece m<4> on the latch. The port j<7> controls a pin h<7> of the series H, and an air conduit n<9> to a cylinder n<15>, Fig. 2, containing a piston valve n<14> controlling a conduit n<10>. The port j<10> controls the justification-space designating-pin H<0> and the supply of air to the conduit n<10>. When the ports j<7>, j<10> are both uncovered, air passes from the conduit n<10> through the valve n<14> to actuate a piston N<1>, which operates ratchet mechanism N<4>, N' to rotate a cam or star-wheel N<7> controlling a valve N<8>. This valve controls the communication between a constant air-supply pipe N<4> and a conduit N'‹ for a piston N<12> connected with the bail L, and is alternately opened and closed at successive shift signals. In a modification, the stops D, D' are arranged to slide, and are connected by linkage controlled by the bail L. Fig. 12 shows the shift mechanism of another modification, in which the stops are projections on opposite sides of a member, for example the die-case draw-rod, mounted for rotation effected through connexions from a link C‹. A latch P on a reciprocating rod P', for example the type pusher, is rocked by either of two pistons Q, Q<1> into position to engage one or other of two double-shouldered projections C", C<10> on levers C‹, C<8>, so that in one journey of the rod P<1> the lever C<8> is set with a stop C<12> or C<13> in position to rock a lever C<7> connected to the link C<6> at the next journey of the rod P<1>. Two shift signals are used, one for each portion Q, Q', respectively in connexion with the pins h<7>, H<0>, Fig. 1, and the pin h<7> and a second pin of the series H, and controlling a supply conduit Q<8> and valve conduits Q<9>, Q<10>. Specification 2949/05 is also referred to.
