Abstract: 27,278. Bancroft, J. S. Jan. 30, [date applied for under Patents Act, A.D. 1901]. Monotype machines.-In type-casting machines of the kind described in Specification No. 8633, A.D. 1899. the mould-adjusting devices are controlled by the record strip which is provided with a special perforation for this purpose. The adj usting-mechanism consists of a series of separatelymovable pins 2, with which co-operate a pair of oppositely-moving jaws 3. These jaws position a stop-bar 4, which in turn determines the closed position of a second pair of moving jaws 5. These are connected by rods 6 with a pair of jaws which move the wedges which determine the size of the mould. Each pin 2 works through a guideplate 7, and is provided with a retracting-spring and a piston working in a cylinder. A pipe leads from each cylinder to one of the ports in the paper-feed mechanism. The jaws 3, 5 are guided upon rods 13 so as to reciprocate over the pins 2. To the jaws 3 are pivoted levers 14<a>, the other ends of which are connected by an adjustable link 15. One of the levers 14<a> is. pivotally, connected by a link 16 with the frame 1, and the other is connected by a linch 17 with an actuating- lever 18 pivoted on the frame. The jaws 5 are pivoted to a pair of levers 19, the other ends of which are connected by an adjustable link 20. One lever 19 is connected by a link 21 to the frame, and the other, by link 22, to the actuating- lever 18. The stop-bar 4 is. guided to reciprocate parallel with the jaws, and is furnished with teeth which receive the end of a locking-bolt 23 which holds the stop-bar after it has been adjusted by the jaws 3. Only one of the jaws 3 projects into the path of the pins 2 when elevated, and, in order that this jaw may advance first, the opposite jaw is connected by means of a lever and link 25 with a spring 24. The actuating lever 18 is connected with the main actuating-lever 390 of the die-case centering-mechanism by means of a link 26 and arms 27, 29 fixed to a rook-shaft 28. The arm 29 is connected through an elastic coupling with a pin 30 on the lever 18. On either side of the pin 30 are bearing-blocks 31, 32. The block 31 is fixed in the end of a sleeve 33 having slots for the passage of the pin 30. To the arm 29 is pivoted a sleeve 34, which surrounds the sleeve 33 and is also provided with elongated openings for the passage of the pin 30. The sleeve 33 is closed by a screw plug 35 and the sleeve 34 by a screw cap 36. Inclined faces are formed on the block 32, to which is attached a rod 38 passing through the plug 35 and cap 36 and secured by nuts or the like. Wedge blocks 39 are pressed by a spring 41 against the inclined faces of the block 32, and through these motion is transmitted to the pin 30 from the arm 29. The locking-bolt 23 receives motion from the actuating-lever 58 of the centering-pin or plunger through a link 42 and a lever 43 which engages shoulders on the locking-bolt. The lever 43 is fast on a shaft 44 carrying an arm to which is attached a rod for operating the locking- bolts of the die-case centering-mechanism; so that both sets of locking-bolts operate in unison.
