1938 Diamond T truck
The Diamond T Motor Car Company was founded in Chicago in 1905 by C. A. Tilt. Reportedly, the company name was created when Tilt’s shoe-making father fashioned a logo featuring a big “T” (for Tilt) framed by a diamond, which signified high quality.[1] The company's hood emblem on trucks was a sled dog in harness. From its beginnings manufacturing touring cars, the company later became known for its trucks. By 1967, as a subsidiary of White Motor Corporation, it was merged with Reo Motor Company to become Diamond Reo Trucks, Inc.[2]
During World War II, Diamond T produced a prototype of a heavy truck in the 980/981, a prime mover which was adapted and quickly acquired by the British Purchasing Commission for duty as a tank transporter tractor. Coupled with a Rogers trailer, the truck gave sterling service with the British Army in North Africa Campaign, where its power and rugged construction allowed the rescue of damaged tanks in the most demanding of conditions.[3] [citation needed] In addition Diamond T built the entire range of the G509 series 4 ton 6X6s, including cargo, dump, semi tractor, and wrecker trucks,[4] as well as some lighter trucks, and even G7102 half tracks.[5] Diamond T ranked 47th among United States corporations in the value of World War II military production contracts.[6] Diamond T manufactured three pickup trucks: The Model 80,201 and the Model 202. The pickups were powered by the Hercules QX-series 6-cylinder engines. The model 80 was produced from 1936 to 1938 and the Model 201 was produced from 1938 to 1949.
Commercial models
1928–1929 brought major mechanical improvements across the entire range. A closed cab with doors was introduced. All-wheel hydraulic drum brakes were used. Six-cylinder engines were available from Continental and Hercules for heavy trucks and a four-cylinder Buda powered light trucks. All trucks had geared-differential rear axles. By 1929 there were chassis load ratings (the weight of the body and payload) up to 12 tons (10,900 kg) on three axles.
1933–1935 In 1933 a new all-steel covered cab with doors and roll-up windows was introduced. In a 1935 model year style change it had been improved with a "streamlined" V-style windshield. This cab would be used on commercial and military trucks until replaced in 1951. In 1935 the trucks were also improved mechanically and new models were introduced. They developed through the rest of the 1930s. In 1935, Diamond T sold 6454 units and in 1936 it increased to 8750 trucks [8]. In 1938, Diamond T sold 4393 units and in 1939 it increased to 5412 trucks [9]. In 1940 Hercules six-cylinder gasoline and diesel engines up to 118 horsepower (88 kW) were used and Cummins diesels up to 200 horsepower (150 kW) were introduced in 1940.
1940–1942 In 1940 Hercules six-cylinder gasoline and diesel engines up to 118 horsepower (88 kW) were used and Cummins diesels up to 200 horsepower (150 kW) were introduced. In 1942 improved models went into production and then stopped after only 530 units for military production of tactical trucks and half-tracks.
1946–1947 Production of commercial trucks was stopped for military production in 1942. A small number of commercial trucks began to be built in 1944 and more in 1945. In 1946, the first year of full commercial production, there were five models, in 1947 there were fourteen. After World War II heavy trucks were measured by Gross Vehicle Weight Rating (GVWR), the total weight of the chassis, body, and payload. In 1947 there were chassis rated from 8,000 pounds (3,600 kg) to 36,000 pounds (16,000 kg) with conventional, sleeper, and COE models. Annual model changes were discontinued and many models continued unchanged until 1950. Gasoline and diesel engines were offered by Continental, Cummins, and Hercules. Single and tandem rear axles were available in many wheelbases.
