Originally known as Pittsburgh Equitable Meter and Manufacturing Company, which was created in 1927 with the merger of two meter companies. They relocated to Brooklyn in 1941. About the same time, they purchased the Crescent Machine Co. Also in 1945, Rockwell purchased Delta Manufacturing Co., and made it its Delta Power Tool Division. Shortly thereafter, Delta tools were labeled "Delta Rockwell".

After that busy 1945 year, Rockwell made a series of product and company acquisitions:

In 1973, Rockwell Manufacturing Company merged with North American Rockwell to become Rockwell International Corp. In 1981, the Porter-Cable line was sold to Pentair Inc. of St. Paul, MN. On April 12, 1984, the remaining machinery and tool operations were also sold to Pentair, which renamed it Delta International Machinery Corp.

If you are looking for parts, service, or manuals for your Rockwell woodworking machine, look also in the entry for Delta Manufacturing Co.
