Patent number: 6505864Abstract: A fabricated connector for oval shaped cross section ducts is provided. The fabricated connector has two oval shaped connector elements, each of which are formed from two semi-circular rings to which universal connectors are permanently affixed on each end of the semi-circular rings by the manufacturer. The semi-circular rings with universal connectors attached are then shipped to the field where angle pieces are inserted and fixed between the universal connectors of the two semi-circular rings to form the precise shape of oval connector desired.Type: GrantFiled: July 3, 2001Date of Patent: January 14, 2003Assignee: Ductmate Industries, Inc.Inventor: Alan B.

Patent number: 6505441Abstract: A duct access door for use with ducts that carry cooking vapors and greases is a “sandwich” type door that has inner and outer plates, the inner plate being positioned inside the duct and the outer plate outside the duct with a heat resistant gasket attached to the outer plate. Strategically located bolts draw the plates together at their corners to provide compression of the gasket and prevent leaking of vapors and greases.Type: GrantFiled: March 15, 2001Date of Patent: January 14, 2003Assignee: Ductmate Industries, Inc.Inventors: Alan B. Shuey, Vincent L. Bloom

Patent number: 6209850Abstract: A damper mounting assembly for mounting a damper within an HVAC duct is provided. A damper mounting assembly has attachment clips secured to the damper blade before the damper blade is positioned within the duct. Shaft segments are inserted from outside the duct through axially aligned holes in the duct and are permanently received within the attachment clips affixed to the damper blade to provide support and control for the damper blade within the duct. A damper control handle is affixed to one of the shaft segments so that the position of the damper blade within the duct may be adjusted and thereafter locked in place.Type: GrantFiled: October 19, 1999Date of Patent: April 3, 2001Assignee: Ductmate Industries, Inc.Inventor: Edward F. Rafalski

Patent number: 5901502Abstract: A duct access door to close and seal a circular opening in an HVAC duct is provided. The access door includes an outer cover which completely covers the circular hole and has a gasket for sealing against the duct. An inner panel fits within the circular hole and threaded fastener bias the outer cover towards the inner panel to seal the circular hole in the duct. Insulation may be provided between the outer cover and the inner panel of the access door if desired.Type: GrantFiled: July 21, 1997Date of Patent: May 11, 1999Assignee: Ductmate Industries, Inc.Inventors: Edward F.

Patent number: 5529092Abstract: An air turning vane and rail assembly for use in heating, ventilating and air conditioning ducts is provided. The rail is formed with tabs that are partially punched from the sheet metal rail and bent to a position perpendicular to the rail. The tabs are further bent to generally approximate the arcuate shape of the vanes to be received by the rail. The tabs extend the full width of the vanes that are positioned on them. Either single walled or double walled turning vanes are positioned on the tabs and the tabs and the vanes are crimped together to retain the vanes on the tabs. Because the tabs extend the full width of the vanes, the vanes are automatically positioned so that they are parallel to each other and so that their vertical center lines are aligned with each other.Type: GrantFiled: March 24, 1995Date of Patent: June 25, 1996Assignee: Ductmate Industries, Inc.Inventor: Bruce C. Arnoldt

Patent number: 5135270Abstract: Apparatus for connecting the ends of a pair of oval duct sections includes a pair of arcuate frame sections and a pair of linear intermediate frame sections that are connected to each other by connector pieces having leg portions extending into receivers in the profile of the frame sections. The connector pieces have stop members which abut the edges of the frame sections and provide a gap therebetween. The lower stop member is offset rearwardly from the body portion of the connector piece and the edge portion of the oval duct extends outwardly into the gap portion. The oval duct end portions are connected to the duct connector frame members and pairs of frame members are positioned in adjacent relation with a gasket member therebetween. The connecting members include a securing device to secure the adjacent frame members to each other and exert a compressive force on the gasket member therebetween.Type: GrantFiled: August 16, 1989Date of Patent: August 4, 1992Assignee: Ductmate Industries, Inc.Inventors: Peter J. Arnoldt, Frederick J. Arnoldt
