Abstract
A clamp for a buttonhole sewing machine includes two curved cantilevered arms which arch forward and downward to parallel feet portion. The clamp is supported on an extension of a movable clamping plate and moves with the clamping plate. A lever compresses a spring, pushing the clamp into firm engagement with the workpiece on the movable clamping plate. A detent holds the spring compressed and the clamp engaged until the end of the cycle, when the detent is released and the spring pushes the clamp upward so that the workpiece may be moved.
