In an effort to protect their business and creative interests, the Bradley and Hubbard Manufacturing Company patented 238 new inventions, improvements to mechanical devices or processes, and innovative product designs over the course of its 88 year existence. Although the company marked their own products with the company logo, making them easily identifiable as Bradley and Hubbard, they also supplied parts for many other lighting manufacturers on which they may have only marked the device with a patent date. This searchable database contains all 238 patents assigned to the company with a brief description of the device, improvement or design, patent date, patent name, patentee or inventor’s name, and the original patent images.
