O.W. Timm Aircraft Company
|Founded||1922 Glendale California|
|Headquarters||Van Nuys, California|
|Subsidiaries||Timm Industries, Inc|
Between 1911 and 1922 O.W. Timm built several aircraft with varying success before he founded, in 1922, the O.W. Timm Aircraft Company. Timm manufactured six models of a parasol design, the Collegiate. In 1934 Otto and his brother Wally Timm joined to form a new company named the Timm Airplane Company to produce the Timm T-S140, a high wing twin engine aircraft using new features developed at NACA such as flaps and tricycle landing gear. Wally Timm formed his own Glendale based aviation company later on, the Wally Timm Inc.
The company developed a "plastic" material made of resin and wood similar to the Duramold process. The Duramold and Haskelite process was first developed in 1937. Followed by Gene Vidal's Weldwood and later the Aeromold process. The Aeromold process differs in that it is baked at a low 100 °F (38 °C) at cutting and forming, and 180 °F (82 °C) for fusing together sections after the resins are added.
In 1939, at the onset of World War II, the company operated as the Timm Aircraft Corporation, building the PT160K trainer prototype using the aeromold process. By 1941, the U.S Navy ordered the aeromold N2T-1 with a production run reaching 260 aircraft along with other small aircraft parts made of the aeromold process. Profits increased to $70,000 from $240 the year prior. The company also license-built 436 of the CG-4A glider used by allied troops. A Plywood construction variant, the CG-4B was developed by Timm in case of material shortages, but did not go into production.
After World War II, the company specialized in returning surplus Douglas C-47 aircraft back into airliner configurations. The company also created a subsidiary, Timm Industries, Inc to manufacture vending machines such as the Frank-O-Matic and Coca-Cola bottle dispensers.
In 1953, a proxy war among shareholders was started, with C. D. Rudolph winning control of the board. The company did not produce any new aircraft after this point.
