Filed:

May 19, 2005

Appl. No.:

11/132341

Inventors:

William Bailey - Plano TX, US
Stephen Carey - Smyrna TN, US

International Classification:

F16K 31/04

US Classification:

137601090

Abstract:

A damper actuator mounting system having a bracket for coupling a power operated mechanism to an air handling duct, the bracket having a support portion which has a plurality of supporting apertures and a plurality of supporting fasteners, and in which the supporting apertures are adapted to receive the supporting fasteners for adjustably securing and supporting the power operated mechanism, and the bracket having a mounting portion which has mounting fasteners and apertures for securing the bracket to the duct.

Appl. No.:

16/248878

Inventors:

- Stittsville, CA
Stephen Dane Carey - La Vergne TN, US

Assignee:

T.A. Morrison & Co. Inc. - Stittsville

International Classification:

F24F 13/14
F24F 13/15

Abstract:

A damper comprises a generally rectangular frame extending between opposed open faces and defining an airflow region. One or more damper blades comprises a substantially air-impermeable vane pivotally mounted between the sides of the frame and pivotable between an open position and a closed position. In the closed position an edge of the adjacent blade abuts a blade stop surface formed along each end, such that in the closed position one edge of the blade adjacent to each end of the frame extends into a recess and abuts the blade stop surface, to prevent air from flowing between the blade and the end of the frame. In the preferred embodiments the blade stop surfaces are integrally formed in each end panel.

Assignee:

T.A. MORRISON & CO. INC. - Stittsville

International Classification:

F24F 13/14

Abstract:

A backdraft damper for permitting a flow of air in an outflow direction and preventing the flow of air in a backdraft direction has a frame provided with a transverse opening allowing the passage of air through the frame. One or more blades extend across the frame and are mounted to the frame about a central portion by pivot members, for rotation between open and closed positions. Each blade comprises a blade body having a leading portion upstream of the central portion, the leading portion of the blade body comprising a channel, a trailing portion downstream of the central portion, the trailing portion of the blade having a larger surface area than the leading portion and comprising a seal disposed adjacent to a distal edge of the trailing portion, for sealing against either the leading portion of an adjacent blade or a blade stop projecting from the frame, and a counterweight disposed in the channel, whereby the counterweight balances the blade such that the blade is biased to the closed position by gravity and movable to the open position by the force of air flowing through the frame in the outflow direction.
