Allen-Bradley

Allen-Bradley is the brand-name of a line of factory automation equipment owned by Rockwell Automation. The company, with revenues of approximately US $6.4 billion in 2013, manufactures programmable logic controllers (PLC), human-machine interfaces, sensors, safety components and systems, software, drives and drive systems, contactors, motor control centers, and systems of such products. Rockwell Automation also provides asset-management services including repair and consulting. Rockwell Automation's headquarters is in Milwaukee, Wisconsin.

The Allen-Bradley Clock Tower is a Milwaukee landmark featuring the largest four-sided clock in the Western Hemisphere.

In 1893 Lynde Bradley constructed his first carbon pile rheostat, used to operate a toy lathe.

In 1901, with $1000 Dr. Stanton Allen and Lynde Bradley developed a current controlled carbon disc compression-type motor controller for industrial cranes in the workshops of the Milwaukee Electric Company, completing it on August 18th, 1901. Milwaukee Electric would soon after adopt the device.

Allen-Bradley began in 1903 as the Compression Rheostat Launch Company in the Pfeiffer & Smith Machine Shop. They signed an agreement with the American Fuse Company of Muskegon Michigan.

In 1904, 19-year-old Harry Bradley joined his brother in the business, and the company's first patented product, the crane controller, was demonstrated at the St. Louis World's Fair the same year. Also in 1904 they started marketing the controller with the Allen-Bradley brand, reasoning that with proper advertising, the name would survive as a valuable entity even if their relationship with American Fuse soured.

In 1909, Dr. Stanton Allen and Lynde Bradley resigned from the American Fuse Company and returned from Oregon to Milwaukee. American fuse offered $10,000 for their patents, a $5,000 dollar lump sum, and employment at a rate of $150 a month. They were politely declined.

In 1910, the company was renamed the Allen-Bradley Company in an effort to distinguish itself from the American Electric Fuse Company's continued fraudulent use of their names and patents.
