Patent number: 7553065Abstract: The present invention is a mixing device and a method of mixing viscous fluids with a mixing device. The mixing device includes a shaft and a first and second supports mounted for rotation with the shaft. A plurality of vanes extend from each support, the vanes defining open ends of the mixer into which fluid is drawn, and openings between the vanes through which fluid is expelled. In use, the mixing device is located in a viscous fluid and the shaft is rotated, thereby effecting rotation of the vanes, causing fluid to move through the vanes and mix the fluid.Type: GrantFiled: January 17, 2008Date of Patent: June 30, 2009Assignee: Site-b CompanyInventor: Ronnald B. King

Patent number: 7473026Abstract: In a method of cleaning a rotary mixing device having a mixer portion and a driving shaft, a shield is located over at least the mixer portion. The mixing device is rotated, expelling material clinging to or trapped by the mixing portion, such as paint, from the mixer portion of the mixing device. This material is blocked or caught by the shield. In one embodiment, the shield is cylindrical in shape and has a base with an opening through which the shaft of the mixing device may extend, and an open second end leading to an interior area for containing the mixer portion of the mixing device.Type: GrantFiled: April 8, 2008Date of Patent: January 6, 2009Assignee: Site-b CompanyInventors: Ross Clawson, Randy Hansen, Jane Wasley

Patent number: 7334936Abstract: The present invention is a mixing device and a method of mixing viscous fluids with a mixing device. The mixing device includes a shaft and a support mounted for rotation with the shaft. A plurality of vanes extend from the support and are mounted for rotation with the shaft, the vanes extending generally parallel to the shaft and positioned radially outward from the shaft. The vanes have a sloping inner edge which is positioned closer to the shaft at a first portion of the vane than a second portion of the vane. In use, the mixing device is located in a viscous fluid and the shaft is rotated, thereby effecting rotation of the vanes, causing fluid to move through the vanes and mix the fluid.Type: GrantFiled: June 21, 2006Date of Patent: February 26, 2008Assignee: Site-b CompanyInventor: Ronnald B.

Patent number: 7226205Abstract: A mixing device includes vanes arranged so that the outer edges of the vanes define a frusto-conical surface in order to facilitate improved circulation of the liquid being mixed. In one embodiment, the outer edges of the vanes are tapered outward to form the frusto-conical surface. In an alternative embodiment, the inner and outer edges of the vanes are aligned with each other, and the vanes are tilted relative to a central axis to form the frusto-conical surface. Turbines extend between the vanes and shaft for rotating the mixing device. The turbines are arranged to avoid inhibiting entry of liquids through the top and bottom of the mixing device. Feet extend downward from the bottom edge of the mixing device to facilitate mixing of liquids on the bottom of the container.Type: GrantFiled: December 5, 2005Date of Patent: June 5, 2007Assignee: Site-b CompanyInventors: Donald Gringer, Yuan Fang Cheng, Howard Soled

Patent number: 6971788Abstract: A mixing device includes vanes arranged so that the outer edges of the vanes define a frusto-conical surface in order to facilitate improved circulation of the liquid being mixed. Each vane is preferably curved, either lengthwise, widthwise, or both. In one embodiment, the outer edges of the vanes are tapered outward to form the frusto-conical surface. In an alternative embodiment, the inner and outer edges of the vanes are aligned with each other, and the vanes are tilted relative to a central axis to form the frusto-conical surface. The vanes may extend between upper and lower rims having the same or different diameters. Turbines extend between the vanes and shaft for rotating the mixing device. The turbines are arranged to avoid inhibiting entry of liquids through the top and bottom of the mixing device. Feet extend downward from the bottom edge of the mixing device to facilitate mixing of liquids on the bottom of the container.Type: GrantFiled: February 27, 2004Date of Patent: December 6, 2005Assignee: Site-b CompanyInventors: Donald Gringer, Yuan Fang Cheng, Howard Soled

Patent number: 6848823Abstract: A method of mixing viscous fluids is disclosed. The method comprises rotating a mixing apparatus (20) in a container (42) of fluid (44). The mixing apparatus comprises a cage (21) located at the end of the shaft (22). The cage (21) comprises a central circular disc (24) with an outer edge (43) and top (38) and bottom (40) sides. A number of vanes (26) extending from each side of the disc (24), the vanes (26) spacedly located near the outer edge of the plate. The free ends of the vanes (26) are connected by a hoop (38,40) to maintain their spaced relationship.Type: GrantFiled: February 6, 2003Date of Patent: February 1, 2005Assignee: Site-b CompanyInventors: David Marshall King, Ronnald Brian King, Thomas Arnold Martin
