Button Hole Attachment

This invention is designed as an improvement on the button-hole attachment for sewing machines for which Letters Patent of the United States, Serial No. 98.778, were allowed me on 27th of October 1883 (Patent US 292.591 dated January 29, 1884). The objects of this invention are to regulate the speed of the form-plate by automatically operating mechanism, to provide improved devices for operating the reciprocating plate, to provide an improved device for barring the end of a button-hole and an improved device for holding and guiding a cording thread or cord and for assuring an even and regular looped button-hole stitch and also to provide improved cloth-clamps and button-hole form plates for such attachments as are respectively designed for light or domestic work and for heavy or manufacturing work.
