Construction of Doors or Window-Sashes.

Patent for "improvements in the construction of doors and window-sashes, the object being to provide a door or window-sash which shall be constructed of two pieces of timber united by means of a key to prevent warping or twisting" (lines 8-13). The panel of the door or the pane of glass can also be united by the key. This design lightens and cheapens doors and window-sashes.
