A type action for a power-driven typewriter comprising
- a pivotally mounted type bar,
- a pivotally mounted intermediate lever,
- a link to connect said type bar to said intermediate lever,
- a toothed power roll, constantly rotating at a normal speed and having teeth at the circumference thereof,
- a driving pawl pivotally mounted on said intermediate lever and having a tooth disposed to be engageable by a tooth of said power roll to be driven thereby to pivot said intermediate lever and accordingly said type bar in a typing direction to effect typing of the character on said type bar, said driving pawl further having a finger and a sidewardly extending lug formed thereon,
- a guide bracket for guiding said driving pawl for motion with and on said intermediate lever,
- means for urging said driving pawl, intermediate lever and type bar to respective normal rest positions in which a tooth of said driving pawl is held cleared of a tooth of the power roll,
- a spring-urged pivotally mounted key lever depressible to a first position and to a second deeper position, said key lever includes an arm extending upwardly in parallel with and adjacent said trigger lever, and said arm of the key lever has at the upper end thereof a cam portion,
- a trigger lever pivotally mounted on said key lever and having a hook and a lug formed thereon,
- a spring stretched between said key lever and said trigger lever to bias the latter to a normal position in which said hook of the trigger lever overlies the top of said finger of the driving pawl, and
- means for preventing said trigger lever from interfering with said driving pawl when said key lever is in said second position,
- wherein said driving pawl is pivoted by said trigger lever in response to depression of said key lever to bring said tooth thereon into the circular path defined by said tooth of the power roll to be subsequently engaged by said power roll,
- said trigger lever is yieldably pivoted when it is engaged at said hook thereof by said finger of the driving pawl during return stroke of said pawl to the normal position, and
- said cam portion of said arm of said key lever is cleared of said driving pawl lug when said key lever is in the normal rest position or is depressed to the first position and is engaged with said lug of the driving pawl during a return stroke of the latter when said key lever is held depressed to the second position to bring said tooth of said driving pawl into the circular path defined by said teeth of the power roll thereby permitting a repetitive cycle of typing operation to be initiated.
