Abstract
555,962. Type-bar making machines. TURNER, H. K. (Mergenthaler Linotype Co.). Sept. 8, 1942, No. 12655. [Class 100 (iii)] Ejecting type-bars.-Ejector-adjusting mechanism of the kind described in Specification 541,166 is controlled by a regularly moving organ of the.machine, such as the justification-lever, as it operates during the first machine cycle after the selection of a mould, and the selection of the appropriate ejector is effected by a rotatable stop-carrier geared to the mould-disc. The selection is effected, as heretofore, through a vertically movable selector-bar E<SP>3</SP>, Fig. 2, operated by a lever E, which is held in adjusted position by a pawl e engaging with a toothed sector mounted on the machine frame. When the mould-driving pinion C is drawn forwards by means of its knob C<SP>4</SP> for effecting a change of mould, it rocks an arm G<SP>1</SP> on - a shaft G, which carries a pusher-plate G<SP>2</SP> adapted to retract the pawl e and release the selector-mechanism for adjustment. The lever E is connected to, and operated by, a transverse lever F, Fig. 1, the opposite end of which is connected by a link J<SP>3</SP> to an arm J<SP>2</SP>, Fig. 6, rotatable on the shaft G. The arm J<SP>2</SP> carries a plunger J<SP>5</SP> sliding in a casing J<SP>1</SP> and supported by a spring J. The upper end of the plunger J<SP>5</SP> bears against the justification-lever H, and the spring J is normally in compression. When the pawl e is withdrawn, the expansion of the spring rocks the levers F<SP>3</SP> E and moves the selector-bar E<SP>3</SP> into its lowest or neutral position, corresponding to an ejector of minimum width. When the lever H rises during justification, the levers F, E are rocked in the reverse direction by gravity, and a banking-slide J<SP>4</SP>, connected to the lever F, is raised into contact with one of a series of stops K<SP>1</SP> on a rotatable carrier K, which is geared to the mould-driving pinion C. The stops are adjustable in a radial direction on the carrier by hand in accordance with the length of the various moulds, and are held in position by rack devices.
