Sash guide and balance lock structure in pivoted window structure, which window structure includes an elongated hollow jamb member having a slot in one side thereof and an adjacent pivoted window sash, which sash guide and balance lock structure comprises a pivot shoe positioned within the jamb member for reciprocal movement therewithin having an opening therethrough aligned with the slot in the jamb member and including resilient tab portions extending centrally from the rear side of the pivot shoe and toward the bottom thereof, on each side of the opening terminating in cam portions, and a cylinder cam including a cylindrical shank having an axially extending non-circular opening therein extending through the opening in the pivot shoe and a flat head having a resilient periphery on the cylindrical shank having notches in opposite portions. Said pivot shoe and cylinder cam being constructed and arranged so that on pivotal movement of the cylinder cam relative to the pivot shoe the head of the cylinder cam moves behind the tab portions of the pivot shoe to expand the pivot shoe to resiliently force the tab portions into engagement with the rear wall of the jamb member and to face the opposite side of the pivot shoe into engagement with the jamb member at each side of the slot. A non-circular actuating member is secured to the window sash and inserted within the non-circular opening in the cylinder cam shank for pivoting the cylinder cam relative to the pivot shoe on pivoting of the window sash with respect to the jamb member.
