  • Patent number: 4343557
    Abstract: A typewriter space bar touch control apparatus comprises a bell crank member, mounted on a support frame, which supports the space bar and a lever member which engages the bell crank when the space bar is depressed more than a small initial displacement. The motion of the bell crank is resisted by a helical tension spring and the engagement of the bell crank by the lever causes an operator to sense a sudden increase in resistance to displacement. Position transducers are provided on the support frame to sense the position of the lever member and the initial small displacement of the space bar corresponds to single space operation and larger displacement corresponds to repeat space operation.
