Claims5
A transmission comprising:
- first input means rotatable in a first direction and an opposite second direction;
- second input means independently operable from said first input means and rotatable in said first direction and said second direction;
- output means;
- engaging means for directly engaging between said first input means and said output means and between said second input means and said output means for transferring rotation of said first input means and said second input means independently to said output means;
- and
- output reversing means, independently operable from said first and second input means and said output means, for providing a first position of said engaging means such that said engaging means transfer rotation of said first input means and said second input means in said first direction into rotation of said output means in said first direction and for providing a second position of said engaging means such that said engaging means transfer rotation of said first input means and said second input means in said second direction into rotation of said output means in said second direction.
