Abstract
The invention relates to tilt-out window assemblies in which a window sash may be rotated from its normal vertical position causing a slide block connected to a spring balance assembly to be locked into place to prevent release of the spring balance assembly on tilting or removal of the window sash from the window frame. The slide block rides in the jamb channel in which the window sash normally slides up and down and incorporates a rotatable locking cam. The locking cam is rotated on tilting of the window sash so as to force a set of locking members against the sides of the window frame jamb channel to engage the block into a fixed position in the channel. The window sash is operatively connected to the locking cam to provide rotation thereof to lock the slidable block. The window sash may be removed from the frame and from engagement with the locking cam if desired.
