Abstract
A window assembly comprises a window sash having a pair of secondary stiles which are hinged to a surrounding frame and at one of their ends to opposite sides respectively of the sash, and operating and locking mechanism including an operating member having three operating conditions whereby in a first of said conditions with the sash in a closed position the operating member locks the sash to the frame, in a second of said conditions the operating member frees the sash from the frame and locks the stiles to the sash to permit tilting of the sash with said stiles from the closed position into a ventilating position and in a third of said conditions the operating member unlocks said stiles from the sash to permit the sash to be rotated horizontally about said one end of said stiles and into a reversed position.

A window assembly comprising a window sash, a surrounding frame, the sash having a pair of secondary stiles which are hinged to the frame and to opposite sides respectively of the sash so that the sash can be tilted with said stiles from a closed position into a ventilating position and can be rotated horizontally about one of the ends of said stiles into a reversed position, and the assembly further comprising operating and locking mechanism including an operating member which in a first condition with the sash in the closed position locks the sash to the frame, in a second condition frees the sash from the frame and locks said stiles to the sash to permit tilting of the sash to the ventilating position and in a third condition with the sash in the ventilating position unlocks said stiles from said sash to permit rotation of the sash with respect to said stiles.
A window assembly including a window sash surrounded by a relatively fixed frame, the sash including secondary stiles between each of two opposite sides of the sash and the frame, a hinge providing a connection between one end of each secondary stile and one of the said sides of the sash, a slidable connection system between each secondary stile and the frame, and an operating and locking mechanism housed in the sash and including a rotatable operating member, a first locking bolt engageable in the frame and two second locking bolts engageable in respective ones of the secondary stiles, wherein with the sash in the closed position within the frame the operating member is rotatable in one direction to cause the first locking bolt to engage the frame, and in the other direction to cause the first locking bolt to disengage the frame and the second locking bolts to engage said secondary stiles respectively to permit tilting of the sash about said slidable connection system and into an open position in which it projects inwardly from the frame for ventilation, and with the movable member in the open position the operating member is rotatable to cause the second locking bolts to disengage the respective secondary stiles to permit rotation of the sash with respect to said stiles about said hinges for reversing said sash.
