This mechanism is a simplified variant of the carpenters’ bench-clamp shown in No. 174. Instead of two jaws that both turn on screws, this design uses a single pivoted clamp working against a fixed side-piece.

180. This only differs from 174 in being composed of a single pivoted clamp operating in connection with a fixed side-piece.

As the screw is turned, it drives the pivoted clamp, causing it to swing and press the workpiece firmly against the fixed side-piece. Because only one jaw needs to move, the mechanism is simpler than No. 174, while still achieving a secure clamping action.
