The Shameless Plug was invented by Patrick Shameless McGuffin in 1921.
(His name is the consequence of the arbitrary spelling of an official at
Ellis Island, when he arrived as a child in 1879, and he didn't want to
call his invention a "McGuffin".) It uses a screw thread to cam out a
series of fingers in the perimeter of the device, which compresses a
washer of vulcanised rubber, asbestos, or some other suitable material,
ensuring an airtight seal. The plug is easily removed by the use of a
spanner, and requires only a plain hole -- no need to cut threads.
Unfortunately there was only a limited market for this device, which
largely evaporated during the Great Depression. The inventor died a
pauper in Milwaukee in 1931, allegedly drowned when a vat of soup
tippled at a soup kitchen.
