‘casing 28. Intermediate lever 52 includes a stud 58 ?xed
for movement therewith. Stud 58 is adapted to coact
with a second longitudinal notch 66 formed in slide bolt
26 such that as remote handle 18 is rotated in a counter
clockwise direction, as viewed in FIGURE 1, intermedi
ate lever 52 will be rotated in a clockwise direction. As
viewed in FIGURES 2 and 3, the clockwise or rightward
movement of lever 52 moves stud 58 to the right to re
