Machine for controllably flying a flag in the absence of natural wind
Abstract:
A machine for controllably flying a flag indoors or outdoors in the absence of natural wind; said machine constituted of a base member having enough depth to house and protect electronic and/or electro-mechanical drive components etc.; said drive components including, but not limited to at least one electric motor mechanically coupled to a drive shaft of a cylindrical centrifugal fan via pulleys; said fan, as well as an air foil member and a flag pole housed in a long tubular wind pipe rigidly secured atop aforementioned base member in such a manner that when the aforesaid motor(s) actuates the aforesaid fan member via the aforesaid shaft, air pulled in through holes on the wind pipe is blown past the aforesaid airfoil, and then past the flagpole and attached flag, thereby causing said flag to rise and flap in the natural manner; an airfoil angle of attack knob atop the aforementioned wind pipe, in conjunction with a motor speed control knob atop the aforementioned base member, providing affective means of changing or modifying the flying pattern or flapping of aforesaid flag; a synthesized music circuit consisting of several songs preferably national anthems or state songs programmed into its memory is looped together with a programmable timer and an LCD display and control panel for permitting timed actuations of the machine ala electronic alarms.
