Flying buttress

Definition and stakes

1911 Encyclopædia Britannica, Volume 10… (1911)

“ As a vertical buttress, placed at a distance, possesses greater power of resistance to thrust than if attached to the wall carrying the vault, vertical buttresses as at Lincoln and Westminster Abbey were built outside the chapterhouse to receive the thrust. All vertical buttresses are, as a rule, in addition weighted with pinnacles to give them greater power of resistance. ”

“ The water from the gutter behind the parapet is carried out on to the backs of the flying-buttresses by means of holes cut through the stonework. Into these pipes are passed which convey the water through to the open gutter channels of the buttresses. The backs of the raking buttresses, though they are sharply weathered to throw the water from them quickly, are also covered with lead as a further protection. These buttresses have carried the thrust of the vaults down-wards with safety for about six hundred years. ”
