A simple yet effective system for cleaning fans and air circulators facilitates the cleaning of ceiling and hard-to-reach units without having to remove the blades or other parts to be cleaned. A flexible bag encloses parts of a fan to be cleaned. A source of compressed air is used for inflating the bag, and a source of vacuum is used for collecting particulates used for cleaning. A user-controlled nozzle is used for spraying particulates against parts of the fan to be cleaned. The user-controlled nozzle terminates in a narrow tube operative to puncture the bag, which is preferably a transparent plastic bag. The source of compressed air and the source of vacuum may share a common vacuum unit with particulate filter such as a 'shop-vac' type of equipment. The particulates used for cleaning may include any suitable abrasive though, in the preferred embodiment, granulated walnut or other nut shells are used. In contrast to devices that clean with liquids, the enclosure may envelope the motor and blades.

Fan cleaning method and apparatus

The invention pertains to a clutch for an oscillating fan wherein the clutch may be preadjusted for producing various degrees of oscillation, but will automatically adjust to a lesser degree of oscillation if the fan movement is restrained due to the fan's encounter with a stationary object. If necessary, the fan oscillation will automatically adjust to 0&#xb0; oscillation if a severe obstruction is encountered.

Oscillating fan clutch

A barrel fan for the heavy duty circulation of air at the floor level consisting of a cylindrical tubular housing having a guarded rotating propeller blade therein. The blade is driven by a belt connected to an electric motor located on the lower exterior portion of the housing preferably shielded by a skirt in ventilating communication with the housing interior for motor cooling purposes. The motor is pivotally mounted and a spring interposed between the motor and housing maintains the tension within the belt.

Barrel fan with enclosed motor

An air circulating fan wherein the fan components are shipped disassembled. All of the fasteners used to assemble the fan components may be operated without tools, utilizing thumb screws and the like wherein the fan is capable of a &ldquo;toolless&rdquo; assembly. A hand operated fan mounting clamp includes a safety device to prevent loosening due to vibration.

Toolless assembled fan

The invention pertains to a universal bracket for mounting a fan motor assembly upon a support structure. The universal bracket consists of a plurality of low cost fabricated components and incorporates an optional dual construction whereby the components may be assembled to form a construction adapted for ceiling mounting or, in the alternative, to form a construction adapted for wall mounting. The components permit quick and easy assembly and disassembly of the universal bracket, and, in either construction, a swivel relationship exists between the assembled components permitting limited universal angular adjustment of the supported fan motor assembly.
