Abstract

1,134,771. Typewriters. SCM CORP. 28 Nov., 1966 [26 Nov., 1965], No. 53193/66. Heading B6F. In a typewriter of the kind having a horizontally sliding platen carriage 12, line-spacing actuators are effected by power, e.g. a motor 74, Fig. 2, through a mechanism 32, 34 which provides an accelerating motion during a first portion of the platen line-spacing action and a decelerating motion during the remaining portion of the line-spacing action. The acceleration motion is derived from a crank 32, adjustably secured in relation to a shaft 30 non-rotatively but slidable in a pulley 84. This pulley is driven by a belt 86 and another pulley 72 driven one revolution each time a torsion spring clutch 20 is operated by a latch mechanism (42, 52, Fig. 3) and a power driven shaft 66. The latch is operated by a key from a link 40 or by an arm 174 extending from an actuator 162 operated from a carriage-return key interconnected by a link 160. Long feed; multiple action keys.-A continuous or repeat line-spacing operation may be effected by depressing the line-spacing key beyond the normal single operation depth. When this is done the arm 42 which is pulled by the link 40, causes, by the extra movement, a finger (152) to move a notch (58) clear of the clutch spring end (60) for as many cycles as the key is held depressed. Variable line-spacing.-The crank 32, Fig. 5, is connected to an actuator 34 which has a pin 112 which rests on a cam surface 114 of a variable line-space lever 116. In a threeincrement line space operation the pin immediately drops into a space between the teeth of a ratchet wheel 36 but if two or one increment spacing is required the cam is moved counterclockwise, Fig. 5, and is positioned by a spring detent mechanism 118-120, 122, 124, 126, 128.
