    • 13,673. Cummings, W. July 31. Windows.-In order to allow sliding sashes to turn inwards for cleaning &c., a portion of the inside bead is hinged, the parting bead is detachable, and the sashes are fitted with hinge sockets or eyes which engage with pivoted plates, or fit over pivots fixed to the frame. The inside bead is fastened by a thumb-screw working in a fixed threaded socket or nut, and the parting bead is fastened by bevelled pin-and-socket plates I, H and a turn-buckle which engages with a slotted plate of the bead. The sash cord is looped round a hook or button D fixed in a recess in the sash stile, and the detached cord is retained by a fixed hook when the sash is turned inwards. Fig. 5 shows one of the hinges of the lower sash. A T-shaped plate K, fixed to the sash, is formed with a lug and socket which interlock with a flap J pivoted to the frame at L. Socket plates of the upper sash engage with pivots fixed to the pulley stile.
