Ventilating Rooms.

An Ingenious and effective appliance to be attached to hinged windows has been invented, for the purpose of ventilating rooms with casement windows, especially sick rooms, hospitals, schools or any other place where an abundance of pure air without draught is absolutely essential. This apparatus, which Is attached to windows hinged to the frame, commonly known as “French casements,” consists of a wooden skeleton framework, projecting vertically at the side of the window frame opposite to the hinges, and has at the top and bottom triangular frames extending to the hinged side of the sash frame. This skeleton frame is filled in with perforated metal, wire gauze, or any other porous weather proof material, and may project either outwards or inwards, according to the direction In which the window opens. The amount of ventilation* may be further regulated by means of a sliding shutter or a blind, which may be adjusted as required to either cover or expose the perforations.
