Valair Inc. Clutch
Answer
•In the early days of transmissions, leather-lined, multiple-disc, oil-bathed clutches were in common use. Although the first use of a dry single-plate clutch was by Duryea in 1893, it was not until 1921 that a design was developed that would not burn out in a few hundred miles, thanks mainly to Englishman Herbert Frood, who perfected more durable friction materials.
