摘要： A new and improved portable zigzag straight stitch walking foot sewing machine comprising a longer needle stroke, a larger presser foot having a radiused bottom, a throat plate having a larger opening therein, an inner presser foot having a relatively high lift permitting the easy insertion or removal of fabric which a new and improved spring loaded connecting rod that operates to prevent the fabric from being drawn into the presser foot opening and feed mechanism. In a specific embodiment, the new and improved portable zigzag straight stitch walking foot sewing machine includes a new and improved throw mechanism which is not biased and a retro fix stop device for reproducibly controlling the stitch length.

摘要： A sewing machine having a locking pin clutch mechanism allowing the user to selectively engage the flywheel or balance wheel for transmitting power to the main drive shaft. The locking pin may also have a line of weakness to function as a shear pin. The locking pin may be removable from the flywheel, and the flywheel retaining locking knob may include an aperture for storing the locking pin. In alternate embodiments, the locking pin may be held captive in the flywheel when the clutch is disengaged.
