angle-brace

Century Dictionary and Cyclopedia

1. n. In carpentry: A piece of timber having its two ends fixed to the two pieces forming adjacent members in a system of framing, and subtending the angle formed by their junction. When it is fixed between the opposite angles of a quadrangular frame, it is called a diagonal brace or diagonal tie, and when placed near a corner , an angle-tie.
2. n. An instrument consisting of a rectangular crank-frame, like the carpenter's brace (see brace), but usually much stronger, carrying a parallel tool-spindle which ends in a pad or bit-socket of the ordinary form, and carries a small bevel-wheel gearing into a second wheel on the axis of a winch-handle, by which motion is communicated to the drill. This tool is chiefly used for boring holes in positions, as corners, where the ordinary brace cannot be conveniently applied. For heavy work it is usually mounted in an ordinary drill-frame. Also called corner-drill.
