Abstract: An upwardly opening generally cylindrical decorative cover including a bottom wall having a central opening formed therein is provided and the cover is upwardly displaceable over the lower portion of a dependingly supported ceiling fan motor controlling switch housing with the central opening in the bottom wall of the cover snugly receive all but the upper portion of the switch housing therethrough and the inner periphery of the bottom wall disposed about the central opening abutted against a mounting flange structure carried by an upper portion of the switch housing and removably anchored thereagainst. The upper open portion of the cover is loosely telescoped upwardly over those portions of the ceiling fan motor projecting below the blades of the ceiling fan and disposed between the blades and the dependingly supported switch housing. The bottom wall of the cover may include openings therethrough for the passage of motor cooling air therethrough.

Abstract: An electric ceiling fan of minimum practical axial depth for conserving needed head room includes a wheel-like frame; a fan motor nested therein; a fan blades assembly nested around and driven by such motor; a shallow support adapted to be attached directly to a ceiling; shallow hanger arms pivotally suspending the frame from the support for generally varying the air flow; a shallow, air pervious upper guard enclosing the motor and fan blades assembly; a step motor nested in the frame beneath the fan motor; a thin air pervious lower guard nested within the frame, driven by the step motor in the same direction as the fan blades assembly, but at much lower speed, and having radially spaced parallel vanes directing the downwardly flowing air in both axial and outwardly inclined, slowly revolving columns, for distributing the air over a wider area, while avoiding excessive air flow and "dead spots" beneath the fan; and a control mechanism including a separate switch for operating the step motor independently of t

Abstract: An arrangement for isolating engine noises and vibrations or the like from the blades of a ceiling fan include a blade-mounting ring, to which the blade irons are directly attached, and a plurality of elastomeric grommets or bushings carried on the ring. Partially threaded studs extend through the grommets and into the rotor cage to suspend the blade-mounting ring slightly below the rotor cage by the transfer of weight of the blades through the rubber grommets. The blade-iron feet enclose the grommets and prevent the inadvertent withdrawal of the stud members therefrom.

Abstract: An improved ceiling fan including a housing to be hung down from a ceiling and a motor having a stationary stator and a rotatable rotor which rotates a number of blades to create a stream of air. One or more electrical heating elements are positioned within the housing and around the outside of the rotor. A radial fan arrangement generates a flow of air through the housing, over the heating elements, and out into the stream of air created by the rotation of the blades.

Abstract: A heated ceiling fan comprising a plurality of blades with heating means in each of the blades.

Abstract: A fan blade, preferably for use with a ceiling fan, is constructed hollow with a top and bottom located so as to provide an air space sufficiently large enough to house one or more germicidal lights, preferably ultraviolet, in such manner that the light will burn while the fan blade rotates. Filtering pads, preferably charcoal impregnated and usually comprised of a plastic foam, are located at the leading and trailing edges of the air space between the top and bottom of the hollow blade for the absorption of smoke and other objectionable odors as the air passes through the lamp area. Preferably the leading edge is provided with pocket means to receive the air. Baffles may be provided to prevent the germicidal light from casting its light outside the confines of the hollow blade. The ends of the blade joining the leading and trailing edges thereof are closed.

Abstract: A ceiling fan is disclosed which is suspended from the ceiling in a conventional manner, and includes a plurality of fan blades secured to a rotatably driven outer portion of the motor assembly. The motor assembly is surrounded by a housing including top and bottom plates in a clamped engagement with an annular translucent panel, disposed peripherally between the plates, and including an annular fluorescent light bulb disposed within the housing in a surrounding relation to the motor assembly, including a support structure to hold the light bulb in a generally central position between the plates.

Abstract: Two position fan blade attachments or blade iron assemblies for sealing fans provide for the individual adjustment of the paddle-type blades into two preselected angular positions providing for either a downward or upward flow of air. The blade attachments provide detents or interengaging locking cams which are maintained in either one of the preselected positions by a spring and by the centrifugal force applied to the blade. In one embodiment, the interengaging structure includes a leaf spring which has two recesses or openings engageable with a ball. In another embodiment pairs of inclined ramps are mutually engageable with corresponding pairs of camming recesses.

Abstract: A compact, combined ceiling mounted fan and lighting fixture (10) that eliminates flicker effect and provides soft, indirect lighting includes a housing (11) capable of being mounted to the ceiling, a fan motor (12) for rotating the fan blades (15) and mounted within housing (11), a light source (13) for generating illumination mounted to the housing (11) above the fan blades (15), and a shield (14) for insuring that substantially all illumination from the light source (13) is projected away from the fan blades (15). A single switching control (45) is provided for operating both a motor speed control switch (41) and a light control switch (42). The switching control (45) extends beneath fan motor (12) and fan blades (15) to permit safe and convenient operation by the user.

Abstract: The invention pertains to a swag kit for ceiling mounted fans wherein the kit includes a flexible electrical conductor supported within a chain, the upper region of the chain being connected to a ceiling plate while the lower region of the conductor connects to a switch box containing a switch for the fan, and may also include a light switch. A line cord is connected to a switch within the switch box, and the ceiling plate functions to electrically isolate the fan connections from the ceiling in compliance with code regulations. Conductor strain relief means are provided at both the ceiling plate and switch box, and a chain receiving hook is homogeneously defined upon the ceiling plate to support the chain without tensioning the conductor.

Abstract: The pitch of a rotating propeller blade is adjusted to selectively increase the pitch of the blade or to selectively decrease the pitch of the blade. The blade is connected to a rotating hub by bearings that allow the blade to change pitch. A two-direction D.C. motor mounted on the rotating hub is selectively energized to increase or decrease the pitch of the blade. A pair of sensors are mounted on the rotating hub at different distances from the hub's axis of rotation. The first sensor is adapted to generate a signal for energizing the motor in a first direction and increase the pitch of the blade. The second sensor is adapted to generate a signal for energizing the motor in a second direction and decrease the pitch of the blade.

Abstract: First and second windmill wheels are mounted on and non-rotatably connected by shaft means, which define a vertical axis. Each of said windmill wheels has rigidly interconnected vanes, which are adapted to return opposite to the direction of the wind. Said two windmill wheels define axially outermost flight circle planes which intersect at an acute angle. The vanes of each of said windmill wheels are adapted to describe an orbital line, which is tangent to a corresponding orbital line described by the vanes of the other windmill wheel at an apex, which is disposed between said flight circle planes. Control means are operable to move said windmill wheels relative to each other so as to move said apex about said vertical axis and thus to vary said angle when measured in a vertical plane that is at right angles to the direction of the wind.
