Abstract: A fan having a rectangular frame including a bottom wall, two side walls, and a top wall, and a motor-driven impeller supported within the frame for causing air to move through the frame in an axial direction. The frame has at least one, and preferably two, stabilizing feet moveable between an extended position, in which each foot projects axially beyond the contour of the fan frame, and a retracted position, in which the foot does not project axially beyond the contour of the fan frame. Resilient elements, such as springs, constantly urge the stabilizing feet toward their extended positions. The stabilizing feet may be pivotally mounted on the fan frame, and stops are provided against which each foot abuts when the foot is in its extended position.

Abstract: A cotton candy making apparatus includes a hollow rotary member to be rotated, the rotary member being provided with a supply port for supplying sugar to the interior thereof and path for delivering molten sugar to a peripheral edge of the rotary member, a heating device located below the rotary member to heat the rotary member and hence heat and melt sugar in the rotary member, a fan for producing an air flow to the rotary member, the fan being rotated together with the rotary member, and a deflection device arranged between the fan and the heating device to guide the air flow from the fan to the peripheral edge of the rotary member. The rotary member has an extended flange extending radially outward from the peripheral edge of the rotary member.
