Abstract: An air curtain mounting structure which includes mounting plates with T-shaped mounting tabs extending upward. Each end of the air curtain cabinet has a pair of slots formed in the upper surface near the side walls of the cabinet. The slots are collinear and a spaced apart a distance equal to the distance between the mounting tabs. The mounting plates are attached to the side walls of the air curtain cabinet. A pair of hollow, parallel, steel channels are provided having a groove in a bottom surface so that the mounting tabs are supported by the channels. The channels may further be attached to cross members which in turn are suspended from rods or triangular brackets. The rods depend from a ceiling or other support structure, while the triangular bracket attach to a wall. Multiple air curtains may be positioned in side-by-side configuration.

Abstract: An overhead suspended fan has a canopy with a top seal on a support shaft and a bottom seal which is mounted on a rim of a cup-shaped member supported above the motor housing bearing and which has an annular portion engaging the inside of the bottom portion of the canopy and an open shoulder upon which the bottom end of the canopy rests; an inner lip on the annular portion of the bottom seal defines a groove interlocking with the rim of the annular member. An outward and downward flaring skirt on the second seal forms a narrow restricted clearance with a frustoconical portion of the motor housing; a second cup-shaped member mounted on the top portion of the housing has a rim extending upward within a depending annulus of the second seal to prevent water flow to the housing bearing.
