| 2002 | Invention patented by Thomas C. Frampton on January 7th, 2002. Abstract: A mounting arrangement for a ceiling fan has one or more blades located in the same semicircle of rotation so as to produce a center of rotational gravity that lies outside the vertical axis of the rotating fan. A ceiling fan has a counter balancing stabilizing member located in another semicircle of rotation to stabilize the rotating weight of the blade(s) so that during operation of the fan, the center of rotational gravity lies on the fan's axis. A single bladed ceiling fan has a blade with an elongated arcuate body that tapers from one end to its other end. A stabilizing member depends from the blade. There is an opening in the stabilizing member for creating drag when the blade rotates. A cover is provided for covering the opening. |
