Patent number: 6170415Abstract: A sewing machine with multiple needles employs, for each needle, a needle bar guide in the shape of the letter “c” and cooperates with a projection. The needle bar guide holds a needle bar by passing the needle bar through holes formed at upper and lower positions of the needle bar guide. Therefore, when the projection is rotated in a boss, the needle bar guide is also rotated, and the end of the needle is oscillated. When the projection is moved back and forth in the boss, the end of the needle is also moved in the same manner. Consequently, a deviation in the relative position between a needle and a rotary hook caused by a slight difference in machining and assembly accuracy can be adjusted for every needle.Type: GrantFiled: September 30, 1999Date of Patent: January 9, 2001Assignee: Brother Kogyo Kabushiki KaishaInventors: Kazushi Inoue, Hitomi Ori, Motonari Nakano, Yoshihisa Nozaki
