Claims22
An apparatus comprising:
- a main gear and a bias gear, wherein said main gear and said bias gear comprise a shared axis of rotation;
- said main gear defining a first hole, wherein said first hole is displaced radially from a center of said main gear;
- said bias gear defining a second hole, wherein said second hole is displaced radially from a center of said bias gear;
- a pin extending through said first hole and said second hole, and having a lobe thereon, wherein said lobe is disposed at least partially within said second hole;
- wherein said pin has a first rotational position and a second rotational position;
- and
- wherein said pin is rotationally locked in said first rotational position and in said first rotational position said lobe is clear of a side wall of said second hole, and wherein in said second rotational position said lobe alters a rotational alignment of said bias gear relative to said main gear, wherein said pin is axially movable in said first and second holes to unlock said pin and allow rotation of said pin from said first rotational position to said second rotational position.

An apparatus comprising:
- a main gear and a bias gear, wherein said main gear and said bias gear comprise a shared axis of rotation;
- said main gear defining a first hole, wherein said first hole is displaced radially from a center of said main gear;
- said bias gear defining a second hole, wherein said second hole is displaced radially from a center of said bias gear;
- a pin extending through said first hole and said second hole, and having a lobe thereon, wherein said lobe is disposed at least partially within said second hole;
- a detent securing said pin in said first rotational position, wherein said detent comprises a spring;
- wherein said pin has a first rotational position and a second rotational position;
- and wherein said pin is rotationally locked in said first rotational position and in said first rotational position said lobe is clear of a side wall of said second hole, and wherein in said second rotational position said lobe alters a rotational alignment of said bias gear relative to said main gear.
4 more elements
An apparatus comprising:
- a main gear and a bias gear, wherein said main gear and said bias gear are positioned relative to one another on a shared axis of rotation;
- said main gear including gear teeth and defining a first hole, wherein said first hole is displaced radially from a center of said main gear;
- said bias gear including gear teeth and defining a second hole, wherein said second hole is displaced radially from a center of said bias gear;
- a pin extending through said first hole and said second hole, and having a lobe thereon, wherein said lobe is disposed at least partially within said second hole and said pin is biased outwardly from said second hole away from said main gear;
- wherein said pin has a first rotational position and a second rotational position;
- and
- wherein in said first rotational position said pin is rotationally locked relative to said main gear and said bias gear, and wherein said pin is displaced into said second hole to unlock said pin to allow rotation of said pin to said second rotational position and to contact said lobe with a sidewall of said second hole to align said gear teeth of said bias gear with said gear teeth of said main gear.
