A cleaning system has a high velocity fan held within an air-directing casing movably mounted between the lower ends of an inverted U-shaped yoke. The blade configuration of the fan assures that air is directed outwardly in a narrow beam. The system rotates about a vertical extendable support tube and the casing and fan oscillate about a horizontal axis through a vertical angle which can extend from horizontal to near-vertical in the upper and lower direction. A crank arm connects to the U-shaped yoke and to one end of a crank rod which connects to the fan casing. Rotation of the crank arm displaces the crank rod so that the casing and fan oscillate about the horizontal axis. The crank arm is adjustable in length by spaced apart holes. The length of the crank rod is adjustable by using a two piece crank rod with the free end of each crank rod piece being adjustably secured to a connecting rod. The newly designed crank rod having additional spaced apart holes provides additional adjustability features.
In a cleaning system having a fan within a casing, a u-shaped yoke supporting the casing and fan providing vertical oscillating movement of the casing and fan with respect to the yoke, a vertical shaft connected to the yoke providing horizontal movement of the system about the vertical shaft, a crank rod movably connected to the casing, a crank arm movably connected to the yoke and the crank rod and having spaced apart holes therein to provide adjustment to the effective length of the crank rod, the combination with the crank arm and the crank rod of crank rod length adjusting means.
In a cleaning system having a fan within a casing, a U-shaped yoke supporting the casing and fan providing vertical oscillating movement of the casing and fan with respect to the yoke, a vertical support tube connected at one end to a supporting overhead mounting surface and the other end connected to the yoke providing horizontal movement of the system about the vertical support tube, a crank rod movably connected to the casing, a crank arm movably connected to the yoke and the crank rod and having spaced apart apertures therein to provide adjustment to the effective length of the crank rod, the combination with the crank arm, the crank rod and the vertical support tube of vertical support tube and crank rod length adjusting means.
