The 1915 GE Three-Star was the second introduction of the "AO" style of fan. Also known as a loop-handle. This fan included a fully cast iron construction, having eliminated the problematic pot-metal components from the previous four years (although the early version of the three-star did in fact have a pot metal oscillator wheel). Three adjustments were made simple by the ergonomic "star" adjustment knobs for oscillations on/off, pivot around the vertical axis, and oscillation range.
These small considerations make using a three-star oscillator an absolute pleasure in this modern age; it is also extremely quiet as a result of the six-blade design. One of the most sought after fans in the GE catalog, this fan is extraordinary in design and function.
