New Window Construction. (ROBERTS' PATENT).

The importance of a constant supply of fresh air 'to, and the withdrawal of impure air from, occupied rooms cannot be too highly estimated. The oldfashioned sliding sash window lamentably fails for this purpose, for the reason that an open window usually results in a dangerous draught or cannot be used in bad weather.

•Mr. Roberts is a civil engineer, who has devoted serious|study to the problem of ventilation, and he has succeeded in designing a window which has already been largely adopted, and which is certain to advance in popular favour as its merits become generally known. Roberts' patent window, as shown in our illustrations, has two superposed sashes, each pivoted at its lower end in the frame, and capable of being securely closed, as shown m fig. i, or inclined inwardly to an angle, as shown in fig. 2, in which position free inlet for air is provided without the possibility of down or side draughts, while vitiated air is allowed to escape. When turned at right angles upon their pivots, as shown in fig. 3,

both upper and lower sashes may be cleaned upon both sides of the glass from the mside of the room. Provision is made for the almost instantaneous

removal of the sashes from the frame when occasion demands. Sash weights are not required with the Roberts' window, but they may be readily attached if it is desired to make the sashes to slide as well as to turn upon their pivots.
