发明名称 Sewing machine positioning pin
摘要 A positioning pin which permits a sewing machine cabinet to be adapted to accommodate a variety of sewing machines. The positioning pin has a flange dividing the pin into two unequal lengths. The positioning pins are received by bores formed in the base of the sewing machine and the cabinet work surface to properly locate the sewing machine with respect to the work surface. The pins may be reversed end-for-end to adapt to sewing machines having bases with differing heights.
