Abstract
A mechanical assembly for alternately producing displacement of a carriage with respect to a carriage track and rotation of a gear mounted on the carriage, in response to torque provided from a single drive motor including: a latching assembly, having a latched state and an unlatched state, operably associated with the carriage for preventing relative movement between the carriage and the track during the latched state; and a locking assembly, having a locked state and an unlocked state, operatively associated with the gear for preventing relative rotation of the gear during the locked state.
Claims6
A mechanical assembly for clutchlessly alternately producing displacement of a carriage with respect to a carriage track and rotation of a gear mounted on the carriage, in response to torque provided from a single drive motor comprising:
- a) latching means, having a latched state and an unlatched state, operably associated with said carriage for latchingly preventing relative movement between said carriage and said track during said latched state;
- b) locking means, having a locked state and an unlocked state, operatively associated with said gear for lockingly preventing relative rotation of said gear during said locked state.
A method of clutchlessly, alternately producing displacement of a carriage with respect to a carriage track and rotation of a gear mounted on the carriage, in response to torque provided to the gear from a single drive motor comprising:
- a) preventing relative movement between the carriage and the track by placing a latching assembly associated with the carriage in a latched state;
- b) enabling relative rotation of the gear while the latch is in the latched state by placing a locking assembly associated with the gear in an unlocked state;
- c) preventing relative rotation of the gear by placing the locking assembly associated with the gear in a locked state;
- and
- d) enabling relative movement between the carriage and the track while the locking assembly is in the locked state by placing a latching assembly associated with the carriage in an unlatched state.
