266,594. James, R. W., (Remington Typewriter Co.). July 12, 1926. Line-locking devices.-A locking-hook when operated by the line-locking stop prevents effective operation of the type-levers by engaging an arm connected to a universal bail operated by the type-levers; as applied to segment-shift machines the locking-hook is arranged to engage the arm in either the normal or the shift position, and the locking-hook may be arranged also to lock the segment-shift means; the locking-hook may be arranged to lock the space-bar by engaging a link in the space-bar action. The machine shown in Fig. 1 comprises (1) a vertically shiftable segment 19 supporting typelevers 17 and a universal bail 51 which is operated by heels 17a on the type-levers, (2) an escapement rocker 14 operated by a forked link 62 engaging an arm 60 on a rock-shaft 58 which is mounted on a bracket 59 on the segment and is provided with arms 56 connected to arms 55 on the universal bail, and (3) a link 79 operated, as described below, by the space-bar 68 and having a lip 80 for engaging the rocker 14. The locking-mechanism comprises a bell-crank 102 pivoted at 106 to the carriage 8 and formed with a lip 105 for engaging a bail 109 pivoted at 111 to the rail 5. A lug 114 on the bail engages a lug 117 on an arm 115 which is pivoted at 116 to the rail 5 and is formed with a locking-hook 118 adapted to engage arms 120, 127 secured to the rock-shaft 58 and link 79 respectively. When the segment is in normal position the locking-hook co-operates with the bottom edge 121 of the arm 120, and when the segment is depressed for shift, the locking-hook co-operates as shown in Fig. 5 with the top wall 122a of a slot in the arm 120. The arm 120 is pivoted by a screw 123 to an arm 119 on the rock-shaft and is adjustably secured by a screw 124 passing through a slot 125. The arm 127 is formed on a slotted member 126 which is adjustably secured to the link 79 by a screw 129. When the bell-crank 102 is rocked by the linelocking stop 90, the bail 109 is depressed and the locking-hook swings by gravity into ergagement with the arms 120, 127 and thereby locks the universal bail and the space-bar, and also locks the segment in the normal or shift position. The lock is released by tilting the stop-rack 88. The movements of the bell-crank are limited by stops on the carriage 8, a spring 108 normally retaining the bell-crank in contact with the forward stop. Case-shift mechanism; shift-key actions.-The segment 19 is guided vertically and is connected by links 49 to arms 46 on a rock-shaft 42 provided with an arm 41 carrying a roller 39 which engages shift-key levers 36, 37. The arm 41 fits loosely on the shaft and is secured to a block 44 which is secured to the shaft by a pin 45. The shift-key levers are pivoted on a stud 31 mounted in a bracket 3-t formed with a comb 35. The segment is normally held in raised position by a spring 29 connected to the pin 45 and a screwed hook 30 mounted in the stud 31. Space-key actions.-The space-bar levers 69 rock on the shaft 42 and are connected by a rod 7) carrying an arm 71 which is provided with a screw 72 engaging a lug 73 on lever 74 pivotally supported on a rocking arm 76. The lever 74 is connected to the above-described vertically movable link 79 having a lip 80 for engaging the escapement rocker 14. A returning-spring 83 is connected to the link. The space-bar carries a metal arm 85 having a pad 86 which co-operates with the base 1 to limit the upward movement of the space-bar. The downward movement is limited by a pad 87 carried by a bracket 87a on the base. Accenting-arrangements. - The accent-type levers 17<x> can print when the universal bail 51 is locked, the heels 17<a> provided on the ordinary type-levers being omitted from the accent-type levers.
