Abstract

Mode selection disk 10, coupler 11, and interposer 12 are pivotally mounted on shaft 14. Pin 15, carried by disk 10, projects through one of the openings 16 in coupler 11 to interconnect the coupler and selection disk for pivotal motion in unison about the axis of shaft 14. Tension spring 19 urges coupler 11 in a counterclockwise direction, pivoting stud 20 against keystem ear 22 to urge key 24 toward the upward position against stop pin 26. Interposer 12 is normally biased toward the full line position shown by tension spring 28 and is moved to the broken line position by actuation of solenoid 30.

Multiple Mode Selection Mechanism

Mode selection disk 10, coupler 11, and interposer 12 are pivotally mounted on shaft 14. Pin 15, carried by disk 10, projects through one of the openings 16 in coupler 11 to interconnect the coupler and selection disk for pivotal motion in unison about the axis of shaft 14. Tension spring 19 urges coupler 11 in a counterclockwise direction, pivoting stud 20 against keystem ear 22 to urge key 24 toward the upward position against stop pin 26. Interposer 12 is normally biased toward the full line position shown by tension spring 28 and is moved to the broken line position by actuation of solenoid 30.

Selection of the mode is effected by the pivotal position achieved by sensing lever 33 when pivoted about the axis of shaft 34 in a clockwise direction. Lever sensing rail 35 moves to a point of tangency with one of the levels 1...5 in accordance with the position of disk 10 and interposer 12.

Under initial machine conditions, sensing lever 33 engages interposer 12 and is retained at level 1. When a given machine condition is satisfied, solenoid 30 is energized, moving interposer 12 to the broken line position when it is not engageable by lever 33.

Then when key 24 is not actuated, sensing lever 33 pivots to level 2 engaging the disk surface 37. When key 24 is depressed, disk 10 is pivoted clockwise causing sensing rail 35 to abut disk surface 38, thus sensing mode level 4. By positioning pin 15 in another aperture 16, the selection of...
