Frame Timbers

The various timbers that compose a frame bend, as the floor-timber, the first, second, third and fourth futtocks, and top-timber, which are united by a proper shift to each other, and bolted through each shift. They are often kept open for the advantage of the air, and fillings fayed between them in wake of the bolts. Some ships are composed of frames only, and are supposed to be of equal strength with others of larger scantling.
