Abstract: 158,539. Lanston Monotype Corporation, Ltd., (Assignees of Indahl, M. C.). Jan. 31, 1920, [Convention date]. Galley -mechanism for single type composing and casting machines. Relates to means for casting type in Semitic and like languages in machines such as that described in Specification 8633/99, and comprises lifter - mechanism having a platform and a wall to support the foot and one side of each type during the raising of a line of type from the linechannel to the galley. The characters on the matrices are reversed, and the lines are delivered to a galley 1, Fig. 1, located at the left of the machine and above the line-channel I from which the line is raised by a pivoted lifter comprising a frame 2 pivoted on a shaft 3. The frame 2 comprises sidebars connected together by a cross-bar 14 and a channel member 15, Fig. 3, which carries a typeline platform 17 and a column-pusher 19 by which the line is pushed into the galley. In the lower position of the lifter, the platform 17 rests upon the type-channel plate 18 which is recessed to receive it, the line being transferred to the platform 17 by the line-hook K. The columnpusher 19 has a stem 20 passing through the members 15, 14, and adapted to be actuated by a lever 21 and a rod 24 from a cam on the known disc M. A bolt 26 carrying nuts 27 serves as a stop for the pusher. A second cam on the disc M operates a lever 29 carrying a rule-operating rod 32 on which the outer end of the line-rule 34 is pivotally mounted. The other end of. the rule slides vertically in a groove in a. guide-block 35 which is adjusted simultaneously with the linechannel, and has an extension 35<1> projecting over the line-channel and serving as a guide for the rear end of the line. The outer end of the rule is adjusted laterally by means of a nut 37. The lever 29 also carries a lifter-operating rod 39 which contacts with a lever 40 pivoted in arms 42 of a hub-member 43 which is journaled in arms 45 on the lifter-frame 2, The arms 42 carry an adjustable stop 48, Fig. 1, which is normally held down on the frame 2 by a strong spring 52, and a stop 47 on the lever 40 is normally held down on the frame 2 by a relatively weak spring 46. The vertical arm of the lever 40 rests alongside a fixed wiper-plate 13 so that, as the rod 39 rises, it lifts the frame 2 until the end of the lever 40 rises above the plate 13, after which the lifter ceases to rise and the lever 40 is rocked against the pull of the spring 46. The rule 34 is simultaneously lifted by the rod 32, but continues to rise after the lifter 2 has come to rest. When the rule 34 has risen above the top of the line of type, the pusher 19 is operated to push the line into the galley. The rise of the lifter is adjusted by means of the adjustable stop 48 on the arms 42. The spring 52 which holds down the arms 42 serves to present damage in the event of the lifter being unable to rise. Owing to the arcual movement of the lifter, the line of type is tilted as it rises, and is not only supported by the platform 17 but also leans against the pusher 19. The lifter may be raised by hand to give access to the line-channel. Specification 28692/10 is referred to.
