Some sources say that his last name is Cummings, and some say it is Cumming. Does anyone know which one is right?Reseacher1996

Source PDF

ATTOW there is just one source, a PDF from twyfordbathrooms.com. The URL for that PDF no longer works, and I had a look at their site map and couldn't see a replacement. I was, however, able to get the PDF from http://web.archive.org/web/20070626202546/http://www.twyfordbathrooms.com/default.asp?path=1;52;8648;8723 Open4D (talk) 11:45, 7 July 2013 (UTC)

S-trap

There seems to be confusion about Cumming(s) and his 1775 patent, particularly regarding the S-trap.

Although his 1775 patent for a valve water closet includes one in the waste pipe, the main elements of his patent were the sliding valve, low-level water inlet and linking the flush valve with the water inlet valve to allow the pan to be emptied, flushed and refilled with a single pull, which were themselves significant enough improvements to warrant his reputation as a sanitary pioneer. Adam Hart-Davis notes that Cumming's patent described the S-trap as "too well known to require a description here" which suggests that Cumming did not invent it himself, or at least that it was not new in this patent. Including claims that he invented the S-trap would seem to be promoting a 'fact' that is not at all certain; it is, however, significant that he included it in the first patent for a flush toilet.
