Abstract: The vertical slide in the latch linkage of an exit device is coupled for vertical movement together with a channel inside the door stile. The channel holds a pair of blocks having inclined surfaces held in touching relation and relatively slideable. The vertical latch-operating rod is attached to the first of the blocks and the other block is secured to the channel by a horizontally disposed threaded adjusting element.

The other block is restricted from lateral movement only by the threaded element, and turning the threaded element moves that block from side to side in the channel to raise or lower the first block as the inclined surfaces slide. This changes the effective length of the rod. The turning of the threaded element may be done from the outside of the door through an access hole.

Abstract: A cone clutch sleeve (18) on a main shaft (15) is moved axially between forward and reverse counter-rotating gears (13 and 14) by a yoke (102) having mirror-image oppositely tapered cams (108 and 109) on opposite sides thereof which are selectively rotatable to engage eccentric rings (132 and 133) on the forward and reverse gears. This engagement drives the yoke away from the one engaged gear and toward the other gear to in turn drive the clutch sleeve out of engagement with the one gear such that torque applied through the cam-engaged gear ring assists clutch disengagement of the one gear such that requisite shift force decreases as speed and torque increases. The eccentric face surface of each ring actuates the yoke and drives the sleeve member out of engagement with the one gear and into engagement with the other gear with a pulsed impact hammer effect due to the eccentricity of the face surface as it rotates in a circumferential plane about the main shaft.
