Abstract:

A single-blade fan apparatus includes a blade assembly having a hub presenting a longitudinal aperture adapted for receipt on the fan apparatus, a single blade protruding radially from the hub in a first direction, and a counterweight body protruding radially from the hub in a second direction opposite the first direction. The hub, blade and counterweight body are formed of a unitary piece of aluminum, zinc or synthetic resin material. A method of constructing the blade assembly includes providing a mold including a hub cavity, a blade cavity protruding from the hub cavity in a first direction, and a counterweight-body cavity protruding radially from the hub in a second direction opposite the first direction, and fitting a removable mold insert in the blade cavity. The first mold insert fills a portion of the blade cavity remote from the hub cavity. Aluminum, zinc or synthetic resin material is then cast or injected into the mold with the mold insert in place to form the blade assembly, resulting in the formation of a blade assembly including a blade having a dimension in the first direction that is shorter than the dimension of the blade in the first direction would be if the injection step was carried out with the mold insert removed from the blade cavity.

International Classification:

A47B091/00

US Classification:

248/346200

Abstract:

A pedestal apparatus for use in supporting a powered fan includes a hollow pedestal, a tubular column including a lower end supported on the pedestal, ballast supported within the interior space of the pedestal for lowering the center of gravity of the apparatus to restrain tipping, and a dampening element disposed within the tubular column for dampening vibration of the apparatus during use of the powered fan. The ballast and dampening element can be provided by the end user, reducing the weight of the apparatus as manufactured and shipped.

Assignee:

Emerson Electric Co. - St. Louis MO

International Classification:

F04D 2938

US Classification:

416202

Abstract:

An impeller for a fan, with improved performance characteristics, has a central hub with a plurality of wings extending radially outwardly therefrom. The impeller also has a plurality of blades, such that each blade is attached in an extending manner from a corresponding one of the wings. When in combination with a fan having a motor, the motor imparts rotation to the impeller in a forward direction. Each blade is angled backwardly, at a selected angle, relative to its corresponding wing and the forward, rotational direction of the impeller. In an alternate embodiment, each wing of the hub has a first portion extending radially outward from the hub and a second, outer portion angled backwardly relative to the first portion of the wing and the forward direction of the impeller. A method of manufacture is provided.

US Classification:

416237

Abstract:

An attachment for improving the efficiency of a fluid circulation device such as a fan comprises a back connector portion for connecting to a fan blade and a lobe which protrudes from a leading edge of the fan blade. An impeller has a plurality of fan blades extending from a central hub, and the impeller is rotated by an electrical motor. The impeller is housed within a fan guard. As the impeller is rotated, the lobes operate to pick up air passing around the preceding blade and continue accelerating the air to increase efficiency and flow.

International Classification:

F04D 2970

US Classification:

416146R

Abstract:

An air circulation fan has front and rear fan guard members, a motor, a propeller, and a removable shroud covering an outer peripheral portion of the front fan guard member. The removable shroud forms an annular ring having a central, air discharge opening. In one embodiment, the removable shroud is formed from an integral piece of elastomeric material. In another embodiment, the shroud is formed from a plurality of identical plastic shroud portions. Each shroud portion is formed of plastic and covers a section of the outer peripheral portion of the front fan guard member. Each shroud portion has clips for clipping the portion to the front fan guard member. In one embodiment, fan blades, conventionally used on box-type fans, having an inner, leading cut-away notch and a trailing flared portion. The presence of the shroud and such blades make the fan useful in agricultural settings, such as in poultry barns. In operation of the fan, the shroud greatly reduces the noise generated by the fan.

Abstract:

A ventilation system is operable to ventilate gases from an enclosed building. The ventilation system broadly includes a ventilation tube, a ventilation fan, and a flexible flow-through coupler. The tube is operable to extend into and out of the building for transmitting gases along the length of the tube. The fan is in fluid communication with the ventilation tube and is located to pump gases along the tube length. The coupler connects and fluidly communicates the fan to the ventilation tube, with the flexible coupler isolating at least part of the ventilation tube from vibration caused by the fan. The coupler comprises a flexible material with a Shore A hardness less than about 50.
