ABSTRACT:
Transparent storm sash panes are carefully measured and precut for particular window dimensions. The precut rectangular pane is positioned in a gauging slot of a storm sash fabricating apparatus in which an adjustable stop is moved into opposition with a punch unit engaging opposite edges of the pane to thereby establish the proper length of a storm sash frame side to be punched from an extrusion of aluminum or the like. The punch is operated to form an interlocking end on one frame side and simultaneously to form such end on another frame side. Two pairs of frame sides thus produced in the apparatus are placed over the marginal edges of the precut pane, the frame sides being of channel formation, and are secured rigidly at the four corners of the pane by corner end caps or connectors having recesses to interlock with punched tabs on the opposite ends of the frame members. Accuracy of size, durability and economy of manufacturing for the storm sashes are assured.
