(1) Amending the introduction to make it clear that Cumming included an S-trap in his design for a valve closet but removing the claim that he invented it (see talk), & noting that he improved the flush mechanism. (2) in 'Career' altering the description of his 1775 patent to make it clear that the valve, not the S-trap, kept water in the pan (as can be seen from the diagram) and that he linked the flush valve and water inlet. undo Tag: Visual edit
