1868.] Practical Carpentry and Joinery. 375 CASEMENT WINDOWS. CASEMENT Windows are such as open on hinges, like shutters ; and are far cheaper than any other windows. The}* are mostlj- made to open inwards ; and offer the advantage over the ordi- nary lift-sash of greater ventilation when open, and no meeting-rail across the middle of the sash when shut, as in other windows. When properly constructed, casement sashes are tighter, admit less draft, and do not rattle in the wind. The objections to casement sashes are twofold : one is the difficulty of exclud- ing the rain from the crevice between the sash and the window-sill ; the other, their liability to swing to and fro, when open, and the difficulty of so regulating them, as to admit a greater or less quan- tity of air. These objections have been completely obviated by an improvement made and patented by Dr. E. C. Evans, of Montgomery county. This improvement consists simply of a mova- ble sill, which is interposed between the bottom edge of the sash and the perma- nent sill of the window frame It is made of a strip of wood, or metal, four or five inches wide, which extends across the sill; and is so constructed, as effect- ually to exclude the wind and rain. The advantage that this weather-strip has over others is, that in it there is one piece extending across the width of the window, thus breaking the joint between the two sashes. It is >y this joint — which is unbroken in all other weather-strips — that the greater part of the rain-water enters. This weather-strip has been in suc- cessful use, for more than two years. A model may be seen at this Office. The Casement-Sash is a very desirable feature in Domestic Architecture ; and it has been long a source of perplexity to the profession, how to manage this favorite feature, without incurring the weather 'penalty. But now we see the way clear ; and thank Dr. Evans in the name of all designers of Gothic, Old Fig. I. Fro. 2. A, The Slip. A, The Slip. B, The Window-Sill. B, Window-Sill.
