Patent number: 11644045Abstract: In one aspect, a fan assembly is provided that can be manufactured while producing a significantly reduced amount of scrap material. More specifically, the fan assembly utilizes a hub ring and one or more hub strips to support a plurality of blades rather than a solid center disc or end disc used by some prior approaches. In another aspect, a method is provided that includes bending a member into an annular configuration and joining end portions of the member together to rigidly fix the member in the annular configuration. The rigid annular member may be used as an end ring, a hub ring, an orifice, or other component, while producing significantly less scrap material than traditional approaches.Type: GrantFiled: December 1, 2021Date of Patent: May 9, 2023Assignee: Revcor, Inc.Inventors: Craig R. Hall, Richard R. Shelby, Dominic Phillip Menoni, Stephen A. Adamski, Michael F. Buckley

Patent number: 9995316Abstract: A blower assembly having a housing and a cross flow fan rotatably mounted to the housing. Rotation of the fan drives fluid flow through the housing and produces an eccentric vortex of fluid flow in the housing. The fan has a circular blade support that induces fluid flow with rotation of the fan which interacts with the eccentric vortex. The circular blade support has at least one flow interrupter configured and arranged to rotate through the interaction of the eccentric vortex and the flow induced by the circular blade support to disrupt the interaction between the eccentric vortex and the flow induced by the circular blade support. In this manner, the at least one flow interrupter reduces the effect of the unstable vortex-blade support interaction on the airflow through the blower assembly which stabilizes the air loading on the blower assembly motor and reduces noise.Type: GrantFiled: March 11, 2014Date of Patent: June 12, 2018Assignee: Revcor, Inc.Inventors: Craig R. Hall, Nathan K. Shoemaker, Stephen A. Adamski

Patent number: 5699869Abstract: A gear box assembly for automatically engaging and disengaging an output gear which is non-rotatably concentrically mounted on a driven axle shaft attached to plural wheels in a children's ride-on toy is described. The assembly includes an electric motor with a pinion driving plural driven gears, and a yoke which is pivotable between two positions and provides a mount for at least one of the plural driven gears. In one position, the yoke pivotally engages the output gear and drives the vehicle's wheels, and in another position, the yoke pivotally disengages the output gear thereby allowing the vehicle's wheels to freely rotate without driving or back-driving the motor or other gears. In the preferred embodiment, the yoke is counterbalanced for rotation about a defined axis. In alternative embodiments, the yoke includes a friction member for developing friction between one of the driven gears to rotate the yoke into engagement.Type: GrantFiled: May 25, 1995Date of Patent: December 23, 1997Assignee: Mattel, Inc.Inventors: Daniel D.
