Abstract
A lock-out assembly having a latching mechanism by which means a plunger may be manually depressed and latched in a lock-out position in which a lock pin is pre-set by engagement with an actuator rod of an empty/load valve or the like, so that in response to axial extension of the actuator rod sufficient to align a locking groove in the actuator rod with the lock pin, locking engagement therebetween will occur to limit further axial extension of the actuator rod, without any further action on the part of the operator. Automatic disengagement of the lock pin from the locking groove of the actuator rod occurs in response to axial retraction of the actuator rod, by effecting disengagement of the latching mechanism to allow a return spring to reset the plunger.
