Button-Hole-Feeding Mechanisms for Sewing Machine

My invention relates principally to improvements in mechanisms for feeding to sewing machines button-holes having one end rounded or eyelet-shaped. The general object of my improvements is to provide a very effective, durable and easily adjustable mechanism, which, when properly combined with a sewing machine adapted to make the common lock-stitch, chain-stitch, or other suitable stitch from a continuous thread or continuous threads, shall be capable of holding and automatically feeding to the stitch forming devices of the sewing machine fabrics having button-holes of various sizes with one end rounded or eyelet-shaped, so as to thereby cause the rapid and thorough binding of the edges of such button-holes all around by a series of over edge-stitches, which radiate along the semicircular end and are substantially parallel along the sides of each button-hole and which, by adjustments in said mechanism, can be made of different uniform lengths and at various uniform distances apart and to firmly bar the narrow end of the button-hole.
