Rockwell Automation Headquarters and Allen Bradley Clock Tower

The Allen-Bradley Clock Tower, owned by Allen-Bradley, a product brand of Rockwell Automation, has long been a landmark in Milwaukee. According to the Guinness Book of World Records: "The largest four-faced clock is that on the research and office addition of the Allen-Bradley Company. Each face has a diameter of 40 feet, 3-1/2 inches. Dedicated on October 31, 1962, it rises 280 feet from the streets of Milwaukee, and requires 34.6 kilowatts of electricity for lighting and power. The original plan for the clock tower date as far back as 1959, when it appears on early drawings for the proposed addition.Created by architect Fitzhugh Scott, the plans included several towers in its design, only one of which would house a clock. This was scaled back, however a smaller tower on an existing building was kept and modified to display the outdoor temperature using a large digital display. The interest in creating the tower was Harry Bradley, younger of the firm's two founding brothers. An inventor, Bradley including in his tinkering several of the clocks which he owned. The current clock tower stands at 283 ft. (86.26 m). Because the octagonal faces are nearly twice the size of the faces of London’s Big Ben, chimes were never added in order to allow Big Ben to remain the largest four-faced chiming clock in the world. Both towers held their respective titles of largest clocks in the world until the completion of the Abraj Al Bait clock tower in Mecca, Saudi Arabia. Each hour hand of the Allen-Bradley Clock Tower is 15.8 feet (4.8 m) long and weighs 490 pounds (220 kg). Each minute hand is 20 feet (6.1 m) long and weighs 530 pounds (240 kg). The hour markings are 4 feet (1.2 m) high.
