The Neatest and Lightest Wind Mill Model Described
A compact wind mill model is praised for simplicity and completeness with few parts, strong construction, and precise tuning. It claims superior wind sensitivity, staying plumb on the tower, and consistent windward facing in gear, unlike mills using side vanes weights or springs.
Self Governing Mill Stays Steady In Varying Winds
Describes a mill that runs more days a year in lighter winds, its self governing design keeps a steady speed across wind velocities, resists storm damage, and never turns when closed despite no weight spring or brake.
Aira Mill Claims Simplicity Through Light Top Iron Load
The claim emphasizes light top tower iron, noting 80 to 90 lbs in the mill top versus 200 to 500 lbs in rivals. It argues heavy, supposedly strong components fail first due to poor construction and describes how the mill sits on the tower after twelve years of construction experience.

Aira Wind Mill Design Claims Superior Plumb and Wind Facing
The article discusses the Aira wind mill that uses a gas pipe mast through a top collar and down four feet into the tower to bear the mill weight. It argues this design avoids tower plumb issues, reduces friction wear, and keeps the mill facing squarely to the wind, unlike competing mills with side vanes or cap-mounted arrangements.

Mills Run Fast or Slow in Wind Says Chronicle
ACommon complaint against self governing mills notes they speed in a stiff breeze before closing and strain towers and pumps, shortening life, or they fail to pump in wind. The same mill may swing to both extremes, while in the Aira the vane is used for a Grid.

Ingenious Windmill Device Promises Frictionless Operation
A description praises a new windmill device by Aira that operates on independent bearings, eliminating wheel weight on the vane. Experts expect it to remain unsurpassed, as it withstands weather changes and reduces friction, appealing to those familiar with windmills.
Windmill Gear Alignment Improves Turbine Response
The report discusses mill design changes that reduce friction and improve wind capture. It notes the Governor's prompt action and describes a main shaft spanning the mill head with the face wheel behind the head, allowing a compact brace and closer vane alignment to the wheel.
Africa style windmill feature boosts steadiness and efficiency
The article extols the Afra mill as superior for storm endurance claiming no brake is needed when closed. It argues the mill stays balanced and plumb, faces wind squarely, and features an Adjustable Stroke to tailor pumping action. It asserts the Afra runs in lighter winds than any mill.
Azra Mill Construction Quality Highlighted
The Azra is built from the best market materials with top workmanship. Castings are premier, shaft is steel, bearings run in Babbitt with oil cups, and wear parts are adjustable for easy tightening.
