A mechanism for converting reciprocating linear motion to rotary motion comprises an escape wheel rotatable in equal angular increments about an axis, a pallet for rotating the wheel, and a ramp member for actuating the pallet and controlling the displacement of the wheel. The escape wheel is rotated by the sequential application of torque by the pallet to pins extending from the face of the escape wheel, and displaced radially from the axis and angularly from each other. The direction of rotation of the escape wheel can be reversed in response to a change in the path of reciprocation of the input member, and the pallet limits rotation of the wheel to the equal angular increments regardless of overtravel of the input member. |
