Popis:	The roofing of buildings in which a vaulted or domed ceiling projects above the level of the wall plate presents a structural problem because a continuous tie beam cannot be used. British and American carpenters adopted quite different solutions to this problem. The British solution was to use a raised tie beam, and variations on this theme were adopted by a number of carpenters from the seventeenth to the nineteenth centuries. It also appears in both British and American carpenters' manuals. In the roof structures of a number of Connecticut churches, however, the tie beam is divided and arranged in the form of a scissors. This type of structure has a structural advantage when used in association with light walls of brick or timber. These roofs form a group associated with Ithiel Town, who was probably responsible for the design.
