Abstract
The present invention is directed to a locking slide block slidably and pivotably mounting a window sash to a side member of a window frame having a vertical jamb channel. The locking slide block has a housing with oppositely disposed sliding surfaces for guiding the housing in the jamb channel. Operably connected to the housing is a locking means for selectively engaging the jamb channel and locking the housing in a fixed position, and a cam for selectively operating the locking means. A sash pivot operatively connected to the cam is operably connectable to the sash. The housing also has a sash pivot retainer spring. A retaining means is utilized to protect a free second end of the retainer spring from bowing and deforming due to forces applied to the window sash in operation.
