Abstract: 420,017. Type-bar-making machines. HART, H., 9, Kingsway, London.-(Mergenthaler Linotype Co. ; 29, Ryerson Street, Brooklyn, New York, U.S.A.) May 23, 1933, No. 14881. [Class 100 (iii)] Assembling matrices ; galleys and galley mechanism; driving-mechanism.-In a slugcasting machine having means for controlling the presentation of the line to the mould a plurality of times to cast a corresponding number of duplicate slugs, the control means are actuated directly from the main drive shaft and are also adjustable to vary the number of slugs cast from each line. This adjustable control means is connected by a lever to a slide on the vice frame, the slide being adapted when moved out of its normal position, (1) to introduce a stop into the path of the line transporter which limits its upward movement to prevent the removal of the composed line therefrom until the last duplicate slug has been cast; (2) to pull forward the control rod, which trips the clutch control dog, and maintains the clutch in engagement until the duplicate slugs are cast; (3) to lock the assembler in normal position during the casting of duplicate slugs ; (4) to effect the operation of a gate which causes the slugs to be delivered into one compartment or another of a galley which holds the duplicate slugs in separate columns. When the slide is returned to normal position, the various members are also returned to operate in the usual way. The main drive shaft M, Fig. 2, is driven through a spring-actuated clutch thrown into action by a trip dog J, which is carried by a cam J fast to the main shaft and disengages the clutch by depressing a stop lever J<2>. The clutch engages when the delivery slide is released by the arm C' which moves the dog J to clear the stop lever J<2>. The trip dog J is also manually controlled from a lever through a :rod J<8> which carries a pin J' adapted when the lever is swung forwardly to rotate a sleeve J<3> carrying an arm J<5> which then engages and moves the trip dog J to engage the clutch. The adjustable control member for the recasting mechanism comprises a member F provided with a plurality of cam members F<1> which may be manually adjusted into and out of alignment with the rear end L' of a lever L. Underlying the cam members F<1> is a ratchet wheel F<3> adapted to be engaged by a stud M<2> carried by a main drive gear M<1>, so that at each complete rotation of the gear M<1>, the member F is rotated through a distance equal to the pitch between two cam members. The lever L is pivoted to a bracket L<1> and is provided at its other end with a pin L<2> which engages between the arms S' of a member S<8> connected to the slide S which is mounted in a channel bracket S secured to the vice frame V, Fig. 6. The pin L<2> may be disengaged from the member S<8> when the machine is not used for casting duplicates. The slide is capable of lateral movement determined by brackets S<2>, S<3> thereon which abut against fixed stops S<4>, S<5> at the limits of this movement. When the slide abuts against the stop S<5> the various recasting mechanisms are rendered effective ; when the slide abuts against the stop S<4>, these elements are inactive, and the line is transferred from the first elevator for distribution and a new composed line delivered thereto in the usual manner. If two duplicate slugs are required the cam elements F<1> are adjusted so that every alternate one is in alignment with the lever L, when the slide S will be moved against the stop S<5> during one cycle of operations, but during the next cycle the slide will return to normal position under the influence of a spring L<6> attached to the lever L ; by adjusting a proper number of cams F<1> to align with the lever L any desired number of duplicates may be obtained. The slide S operates the recasting mechanisms as follows : The movement of the transporter E may be limited by a stop V<1> pivoted to the vice frame adjacent the transporter, which is then rotated to bring an arm V<2> beneath an adjustable projection E<1> on the transporter slide, so that the latter cannot ascend to its uppermost position and the transfer of the line is prevented by a pin on the transporter, which is not raised sufficiently high to clear a projection on the transfer slide. The stop V<1> is rotated by a pin S<10> adjustably held in the bracket S<2> of the slide S and engaging a notch V<3> on the member V<4>, which is pivotally attached to the stop V<1> so that it can be swung down out of engagement with the pin S<10>; as the slide S<1> moves to the right, Fig. 6, i.e. towards the stop S<5>, the stop V<1> is rotated into its active position. The clutch dog J is rendered inoperative by the movement of the slide through a plate J<10> which is pivoted to a bracket J<9> on which is carried the rod J<8> operating the clutch release dog. On the operative movement of the slide, a pin J<12> on the plate J<10> is engaged by a dog S<11> pivotally attached to the slide and spring- pressed against the pin, and swings the plate J<10> and thence moves the rod J<B> to effect the clutch engagement, which is maintained until the slide is retracted. The assembler B is locked by the movement of the slide through a dog K which is swung into alignment with a lug B<1> on the assembler. This is effected by mounting the dog on a rotatable rod K', the lower end of which carries an arm K<2> and set-screw K<3> adapted to abut against a rearwardly projecting arm j<2> of the manual clutchcontrol lever j, so that when the rod J<8> is pulled forward by the slide S<1> for setting the elements for the recasting operations, the lever j is displaced and consequently the dog K is swung into alignment with the lug B<1> on the assembler, and remains there until the slide S is withdrawn, when the spring K<4> effects its return. A more positive return of the dog K is effected by the space-band lever when the transfer slide is operated after the casting of the last duplicate slug, when a dog K<6> on an upstanding arm K<5> at the front end of the space-band-lever rockshaft G<3> contacts with a pin K' on the vertical shaft K<1> and positively pushes the assembler lock dog out of alignment with the assembler lug B<1>. The galley R is provided with two compartments for holding the slugs in separate columns in order that duplicate slugs may be kept apart. The compartments comprise an upper one R<2> and a lower one R<3>, and the first slug is ejected into the lower and the duplicates into the upper compartment, this being effected from the slide S by means of a vertically-moving gate R<1>, which is carried by a pivoted arm R<4>. When the slide S moves to the right, the arm R<4> and the gate R<1> are raised by means of an upstanding pin S<15> fixed to the slide and projecting upwardly into engagement with a downwardly sloping plate R<5> attached to the pivoted arm R<4>; upon the return of the slide, the gate is lowered by gravity.
