Fans for use with turbine ventilators, and methods and apparatus for supporting the same
First Claim
1. Method for positioning and supporting a revolving fan for use in conjunction with a rotary turbine ventilator, comprising positioning the fan adjacent to but outside of the air inlet of the rotary turbine ventilator with the axis of the fan directed toward a central part of the air inlet in the direction of air flow from the fan, and providing a support for the fan in the described position, whereby the fan when operated to impel air into the ventilator inlet will cause aspiration of additional air into the inlet from around the air stream delivered by the fan into the inlet.

- 6. In combination with a rotary ventilator and a fan-motor assembly mounted beneath said ventilator, apparatus comprising a first elongate element adapted for connection at an intermediate point of its length to the motor of said fan-motor assembly, second and third elongate elements each bendable to L-shaped form intermediate of their lengths whereby one end of each of said second and third elongate elements may be connected to supports at opposite sides of said rotary ventilator and the other end of each of said second and third elongate elements may be connected against the opposite ends of said first elongate element, said other ends of said second and third elongate elements being disposable in line with or at any angle to said first elongate element whereby said one ends of said second and third elongate elements may be connected to supports at different distances apart, said second and third elongate elements being bendable at different points of their lengths to adjust the fan distance from the rotary ventilator.
- 11. In combination with a rotary ventilator and a fan-motor assembly mounted beneath said ventilator, apparatus comprising an elongate element adapted for connection at an intermediate point of its length to the motor of said fan-motor assembly, a pair of L-shaped elements each connectable at the other end against opposite ends of said elongate element, said other ends of said L-shaped elements being disposable in line with or at any angle to said elongate element whereby said one ends of said L-shaped elements may be connected to supports at different distances apart.
