Abstract: III. Disclosed is an air make-up unit mounted within the confines of a conventional outside wall of a frame buildins between the 16" on-center studs. The unit includes a rotary blower with a horizontal tangential discharge, the latter having heating elements therein and being encased in a vertical wall of insulation which extends within an insulated air chamber defined by a telescoping outer casing. Positive air pressure is maintained within the building by air-pressure-sensitive controls located within the building and controlling the two-speed motor. The latter is thermostatically controlled to be operated at a slower speed when colder weather prevails. It is also controlled and energized by a humidistat located within the building to force outside air into the building and diminish the humidity therein when needed.

Abstract: LIGHT GAUGE SHEET METAL FORMING MACHINE of the Invention A semi-automatic sheet metal forming machine for forming light gauge metal having a bed formed of a plurality of adjustable and interchangeable spaced spacer plates of various widths, a forming bar having a plurality of removable and interchangeable forming fingers of various widths, and a clamping bar including a plurality of removable slidably mounted clamping fingers of various widths, she clamping bar and forming bar being hydraulically operated and synchronized for semi-automatic repeated forming operations. By adjusting and utilizing different width combinations of the clamping and forming fingers and spacer plates, an operator can perform almost any desired sheet metal forming operation which heretofore would have required separate and expensive special dies. .
