Definitions

  • This invent-ion relates to escapement mechanism for controlling the. movement of the typewriter platen: carriage in front stroke HWewriting machines in which the 5 inio-vemient or spacing is prod-uceld by means 7 of a double-armed lever which-is struc k'by the type bars near the printing point.
  • Aflfnrther advantage .ofjthe invention is 7 that it enables ,.a much more compact ar rangement of'the parts :to be attained than. has hitherto been possible since, in the new' 35 a device, twosmallstraightlevers which take up little space are used and the dog-rocker and escapement wheel are situated behind thesaid levers.
  • the invention has the advantageover the well-known devices that the well-known noise and clatter I of the escapement'mechanism is reduced to shows the typewriter with the I escapement vl brought about by .the double-armed lever which is control-led 'by the type bars, 'en- II Furthermore, the newdevice can beused I I I I II I I ';p0rt l8 r estsf on a bracketfflrl. mounted onthe carriage support 23 accompanying drawing in which.
