In 1902 catalog Lunkenheimer added the acorns to all of their chime whistles. In 1906 all of the plain and chime whistles carried the acorns on the dome. The only exceptions were the Mockingbird and Fire Alarm, which retained the bald dome. In this year also, all of the whistles with integral valves had gone to the adjustable fulcrum allowing the lever to be attached in an infinite number of directions.
By 1906, the locomotive style vertical valve had disappeared from the line-up. Also, in 1906 a long bell whistle was added, sporting a 3:1 length to diameter ratio. A flanged base whistle also was added in the same year. By this time the side arms of the three bell chime manifold lost their gentle curves and became almost straight.
In 1912 an extra long (4:1) bell iron whistle in sizes up to 12” was added and the vertical valve or locomotive style whistles made a brief reappearance.
In 1918 a patent was granted to Lunkenheimer for their reversible lever that could allow the lever to be mounted in two different positions.
In 1920 the Lunkenhimer catalog shows an iron single bell chime in sizes ranging from 2” – 4” diameter
Over the next 80 years the product line remained relatively unchanged The fire alarms, Mockingbirds and three bell chimes were ultimately dropped, but the complete line of plain bell and chimes whistles remained virtually unchanged over the years. While still in business as a producer of specialty valves, the Lunkenheimer Company produces whistles on a very limited scale.
