Pull chain bulb socket

In 1896, the first U.S. patent for an electric light bulb socket featuring an on-and-off pull chain was issued to Harvey Hubbell of Bridgeport, Connecticut (No. 565,541). On 8 Nov 1904, he patented a separable electric plug (No. 774250) adapting an Edison screw socket to a flat prong style. His inventions are now familiar throughout North America. His manufacturing company, Harvey Hubbell Inc. still exists today.
