Abstract

539,919. Type-bar-making machines. INTERTYPE, Ltd. Nov. 1, 1940, No. 15990. Convention date, Dec. 30, 1039. [Class 100 iii)] Assembling and distributing matrices. In machines adapted for handling 72 and 90 character founts, and having two distributers, two fixed assembler entrances, and a single set of key-operated rods adjustable by means of a hand-lever for releasing matrices from either magazine of a pair, a single adjustable distributer box, adapted to direct matrices to the proper distributer, is also operated by the hand-lever. The esoapements are operated by two sets of rods 16, 17, Fig. 1, adapted for 90 and 72 character founts respectively, and either set is actuated by a single set of key-operated rods 27 mounted in a swinging frame 28, which is adjusted by means of a hand-lever 30. The hand-lever also acts through a link 60 and a lever 64 to adjust a pivoted distributer box 52, shown in plan in Fig. 6 into engagement 'with one or the other of two distributers 22, 23. The distributer-box is carried by an arm 53 movable about a pivot 54 and is locked in either position by a lever 83, which engages in notches 84, 85. The lever 83 is itself locked by a pawl 90, which is withdrawn by one or the other of two pins 94, 95 on the distributer shifter-slide, 58 that transfers the matrix line to the distributer. A change of distributer therefore cannot be made whilst there are matrices undelivered to the distributer. When the pawl 90 has been withdrawn, the locking-lever 83 can be retracted by a cam-lever 77 operated from the lever 64. A lost-motion connection allows the lever 83 to be moved before the distributer-box is shifted. Change of distributer after composition is prevented by a locking-bar, which is moved into the path of the hand-lever by the assembler-slide when the first matrix enters the assembler. Means are provided for preventing a magazine containing a 72-character fount from cooperating with the lower assembler-entrance 19, which is designed for 90-character founts. The 72-character magazines are wider at their lower ends, and rollers are provided on the machine frame between which a 90-character magazine can pass, but which support a 72-character magazine at a level at which its escapements cannot be operated. Specifications 14582/90, [Class 100]. 262,670, [Class 100 (iii)], 422,524 and 532,723 and U.S.A. Specifications 1,202,719 and 1,960,182 are referred to.
