Gormully & Jeffery was an American bicycle company, founded in Chicago by Thomas B. Jeffery and R. Phillip Gormully in 1878. It was at one time the second largest bicycle manufacturer in the US, and was sold to the American Bicycle Company in 1900.
The Rambler is an American bicycle brand manufactured by the Gormully & Jeffery Mfg. Co., in Chicago from 1878 to 1900. This bicycle brand was created by Thomas B. Jeffery and was the predecessor to Jeffery's Rambler automobile.
In 1897 Jeffery built his first automobile, it was a simple single cylinder car with bicycle wheels. It was a forerunner of the 1901 Rambler Model A.[1]
In 1900 Thomas B. Jeffery sold his successful bicycle company to focus on Rambler automobiles after the exhibition of a $900 Runabout at auto shows got favorable responses.
The Rambler was still a proud piece of machinery when low prices took precedence over high quality. Its body featured flared metal tubing for extra strength at the joints, which were brazed by immersion in molten brass. These techniques continued even after Gormully & Jeffery (G&J) and Rambler became names of the American Bicycle Company, or Bicycle Trust, which was not known for the best manufacturing techniques in all of its lines.
Thomas B. Jeffery was an inventor and bicycle manufacturer with his partner, R. Philip Gormully, who built and sold Rambler bicycles through his company, Gormully & Jeffery Mfg. Co., in Chicago from 1878 to 1900. The Rambler was still a proud piece of machinery when low prices took precedence over high quality. Its body featured flared metal tubing for extra strength at the joints, which were brazed by immersion in molten brass. These techniques continued even after Gormully & Jeffery (G&J) and Rambler became names of the American Bicycle Company, or Bicycle Trust, which was not known for the best manufacturing techniques in all of its lines. By 1900, Gormully & Jeffery was the country's second-largest bicycle maker and Jeffery had gained fame for developing, among other things, the clincher rim that enabled pneumatic tires to be used.
Jeffery's patent
Invention of Clincher Rim
Dunlop's pneumatic tires for bikes were pretty much like the garden hoses they started out as. They were tubular in shape, and were secured to the bike rims by glue, and air pressure pressing them against the rim. The rims were wooden, and had a concave surface for receiving the tube. These tires sometimes came off the rims, and a more secure type of tire was needed. Thomas B. Jeffery came up with an improved tire that was held on by a wire that was embedded in the rubber of the tire, and the wire could be tightened onto the rim. He got a patent on the ancestor of all clincher tires in 1882.
