Abstract
A mechanism for controlling functions such as step-by-step carriage return, line spacing and rapid carriage return in a typewriter comprises a single cam adapted to oscillate a single actuating member. The actuating member carries a selector which can be positioned to selectively actuate levers controlling the various functions. The selector is positioned by a single lever which is tilted by different amounts by sliding bars each associated with a key corresponding to a given function. In its rest position, said lever locks the actuating member with the cam disengaged from a driving roller.
Claims9
In a typewriter, a mechanism for selectively controlling at least two functions, said mechanism comprising a driving member, a single cam cooperating with said driving member, control levers for each of said functions, an actuating member acting on said control levers, a selector member carried by said actuating member for selectively coupling said actuating member to the control lever of the selected function, a single lever providing means for placing said cam in driving contact with said driving member and for positioning said selector member, and means for selectively acting on said lever to select each of said functions.
In a typewriter, a selector mechanism comprising a single movably mounted first member;
- means for moving said first member with an oscillating movement;
- a piece movably mounted on said first member between a plurality of discrete positions;
- a plurality of movably mounted second members controlling a plurality of respective functions to be performed, said second members being disposed so as to be selectively actuated by said piece during an oscillation of said first member according to the position of said piece on said first member;
- and means for selectively positioning said piece on said first member to cooperate with at least one second member.
In a typewriter, means for selectively controlling a plurality of levers, said means comprising an actuating member, means for transmitting movement between the actuating member and said levers, a single cam causing displacement of said actuating member, said means for transmitting movement comprising a single selector member carried by said actuating member and displaceable into a first position in which it transmits movements of said actuating member to one of said levers and in a second position in which it transmits said movement to another of said levers.
