ABSTRACT:
A motor driven caging system for free gyros which cages both the inner and outer gimbals thereof and locks in both the caging and uncaging positions by an over center mechanism is disclosed. The motor drives a crank which in turn drives a somewhat compliant linkage which actuates a cam to first cage the outer gimbal and a fork to then cage the inner gimbal. The crank moves through an angle somewhat over 180 degrees between the caged and uncaged positions, with the caging mechanism having a maximum motion slightly less than that encouraged by the crank extreme, whereby the compliant linkage is elastically deflected as the crank moves past the maximum excursion point to a positive stop soon thereafter. Control of the motor is provided by a switch actuated by the caging mechanism drive as it approaches either the caging position stop or the uncaging position stop.
