Abstract: A sewing machine having a substantially U-shaped structure includes a bed section, a barrel section connected to the bed section in a substantially perpendicular fashion, and a bracket connected to the arm barrel section in a substantially perpendicular fashion and extended substantially parallel to the bed section. The bracket includes an opening at an upper surface of the bracket and an arm cover engageable with the upper surface of the bracket for closing the arm opening. The arm cover is substantially flush with the upper surface of the bracket when engaged with the upper surface.
