ABSTRACT:
A weathertight sash window assembly including a pair of first and second engaging members disposed on and extending longitudinally of a pair of meeting first and second stiles, respectively. The first engaging member is movable between a first position in which the first engaging member pulls or draws the second engaging member toward the interior of the window assembly to force the second stile firmly on to the first stile throughout their length and a second position in which the first engaging member releases the second engaging member to allow the second stile off the first stile. The sash window assembly further includes means on the first stile for moving the first engaging member between the first and second positions in response to movement of a first fastener member between its locked and unlocked positions.
