You can find most blades on our ceiling fan blade accessories page. Work stations are ergonomically designed for ease of operation. 3.  Contact Us   | 5, an illustration is offered of the usual distortion which accompanies the formation of the mounting pad by typical prior-art methods. When the temperature rises, flip the switch on the gorgeously rendered Sabal Palm Island Ceiling Fan to cool down your space. This invention relates to a process for forming a sheet metal fan blade of a type particularly adapted to be employed in conjunction with the fan in an automotive cooling system. Thus, a ceiling fan only moves the air around. Then, a stamping die set is formed which has a configuration similar to that shown at FIG. A ceiling fan blade includes a foamed layer, two paper layers, and two cover layers. In the formation of certain types of fans, it is desirable from an aerodynamic efficiency standpoint to make the fan blade of cylindrical form and of any desired outline. The term cylindrical, as used in the claims, is intended to embrace conical shapes as well as cylindrical shapes. The designe of the fan , baldes,and all the other such parts are carried out in the Reaserch and Development ( R&D ) department . The simultaneous provision of rib 16 with the flat mounting pad precludes the distortion into regions such as 24 and 26 of FIG. SECURITY INTEREST;ASSIGNOR:ELJER MANUFACTURING, INC.;REEL/FRAME:006587/0240, Owner name: As the hot air rises up, the blades of the fan slice this air and push it down. 1.
