Abstract

Fig. 1 shows the normal position of the control armatures 10, 12, 14 without a magnet actuated. The air gap on the middle armature 12 is double the gap of the other two 10 and 14.

Velocity Control Mechanism

Fig. 1 shows the normal position of the control armatures 10, 12, 14 without a magnet actuated. The air gap on the middle armature 12 is double the gap of the other two 10 and 14.

In Fig. 2 the velocity-control armature 10 is shown picked and sealed when its coil 11 is activated. The middle armature 12 has been pulled down with the velocity-control armature and its air gap is now half what it was. This would be the condition of the middle armature whether one or both of the outside coils are activated. The bellcrank 16, which latches and unlatches a secondary mechanism, has moved as a result of the motion of the middle armature 12, but is still in a latched state.

In Fig. 3 the middle coil 13 has been activated, in addition to the velocity coil 11, bringing it to the sealed position. This final motion to the middle armature 12 moves the bellcrank 16 to a position that releases the secondary mechanism latch 18.
