An improved window assembly of the type having sliding, pivoting sashes, includes a window frame having a pair of jambs, a jamb liner secured to each of the jambs, a sash which is slidable within the jambs, and a frictional positioner shoe disposed within a channel in the jamb liner. The frictional positioner shoe provides frictional engagement between the sash and the jamb liners to securely hold the window in a raised position, and providing additional restraint against vertical movement of the shoe and rotational movement of the sash when it is tilted away from the plane of the window opening. Also provided is an improved window of the type having sliding, pivoting sashes, which include an elongate slidable member disposed within a channel in the jamb liner, and a rotatable member having an integrally attached brake member disposed within a bore passing through the elongate slidable member. The rotatable member has axial camming surfaces which engage complementary axial camming surfaces on the bore passing through the elongate slidable member. A pivot shaft connects the sash with the rotatable member, whereby rotation of the sash causes rotation of the rotatable member and engagement of the complementary camming surfaces, resulting in axial movement of the rotatable member toward and into engagement with a back wall of the channel.
