Thomas B. Jeffery was born in Stoke, Devonshire, England. At the age of eighteen he emmigrated to the United States, and moved to Chicago. Later he worked making models of inventions for submission to the U.S. Patent Office by inventors. With partner R. Phillip Gormully he formed a bicycle company and became the 2nd largest bicycle manufacturing company in the U.S. One of his accomplisments was developing a clincher rim and tire so that pneumatic tires could be used more effectively on bicycles.
The Gormully and Jeffery bicycles included a model called the Rambler. In 1900 Jeffery and Gormully sold their interest in their bicycle company and bought a factory in Kenosha Wisconsin, and began making automobiles. They kept the mark Rambler, and their cars were called Ramblers. This is Jeffery’s first automobile. Some of his early designs had a front mounted engine, and a steering wheel, but his first production models conservatively followed the Duryea pattern, and had a tiller and a rear engine.
The Ramblers costs in the $750 to $850 range, and has an 8-hp, 1.6L, 1-cyl. engine mounted beneath the seat. In the first year of sales the Rambler became the second largest selling car, with 1500 automibiles sold, second to Oldsmobile.
