Industry History | Rockwell Automation — One Thousand Dollars for a Crane Controller in Walker's Point
kevin
People treat Rockwell Automation as a Milwaukee campus at 1201 South Second Street that always sold FactoryTalk software and a four-faced clock.
The first book was a carbon-pile rheostat for industrial cranes.
In 1903 Dr. Stanton Allen and Lynde Bradley formed the Compression Rheostat Company in the Pfeiffer and Smith machine shop in Walker's Point, with a one-thousand-dollar investment in 1903 dollars.
Lynde had already built a carbon-disc controller in Milwaukee Electric workshops; the pair finished a current-controlled version on 18 August 1901, and Milwaukee Electric adopted it.
In 1904 nineteen-year-old Harry Bradley joined his brother, and the crane controller was shown at the St. Louis World's Fair.
The firm took the Allen-Bradley name in 1909.
Wartime panels for Navy ships, then small resistors that went into Depression-era radios, kept the shop on South Second Street while the plant grew around it.
The clock tower that still faces the harbor district was finished with a 1960s renovation and became the public face of the works.
Rockwell International bought Allen-Bradley in 1985 for 1.651 billion dollars in 1985 dollars, then the largest acquisition in Wisconsin history.
The mechanism has not changed.
A mill or a crane needs a controller that can take current without burning the motor, and the shop that first sold that box still sits on the same block.
A visitor walking South Second Street sees the clock before the software campus.
The brand outgrew the machine shop.
The shop is where the controller started.
