ABSTRACT:
There is disclosed a metal window frame in which balance mechanisms are positioned in the upper portions of the jambs adjacent the sides of a fixed pane or panes, the front faces of the housings for such mechanisms being in a plane parallel to the outer face of a sash that is slidable from a closed position in the lower portion of the frame to a fully open position in the upper portion thereof. The mechanisms and sash are coupled via identical foot structures which are attached to the lower ends of the balances, and which have hook portions extending through the plane of the outer face portion of the sash so as to maintain engagement with the lower end of the sash throughout its normal movement. Catches in the jambs limit the upper position of the foot structures when the sash is raised to an uppermost position for removal from the frame. In takeout position, the sash is movable laterally so that one side passes into the adjacent jamb without contacting the balance, the other side of the sash clearing its jamb so it can be swung clear and permit the sash to be lifted out of the frame. Upon reinsertion of the sash and lowering it, respective hook portions of the foot structures are automatically engaged by the sash for normal operation.
