Definitions

  • the invention relates to improvements in or modifications of the key-controlled driving mechanism for typewriters, type-setting machines or the like,.claimed in my U. S. A. Patent 1,652,430, and consists firstl inthe fact that in order to eliminate the -shaped operable members or connecting rods for the cams or eccentrics illustrated in the constructional example of the main patent a pivoted yoke or cam carrier is formed which acts on the connecting rod, preferably on the end thereof.
  • The'pivoted yoke or cam carrier in this case preferably carries both the locking device and, if desired, the spring for .holding the eccentric or cam in the position
  • the pivoted yoke or cam carrier preferably receives its rearward movement from the connectingrod and is limited in its rearward movement by 'a .stop.

  • the push lever 2 is conne'cte at one endwith a spring 3, while the otherend faces a locking pawl 4.
  • the pawl 4 prevents an eccentric disc or cam 5 from rotating in the direction of the'arrow a.

It is subjected to the action of a spring 9, which is likewise secured in the eccentric pivoted yoke. --The pivoted yoke is held by a buffer 16 in such a way that no undesiredcontactof the eccentric" 5 with the rotating yoke a short distance towards the right ( Figure 1).
