ABSTRACT:
A sewing machine frame and cover construction and fastening means for securing a warped cover in place over a frame opening without imparting frame distorting stresses. To obviate imparting stresses to the sewing machine frame as result of clamping a warped cover thereto, surfaces are provided at locations on the frame and cover chosen so that the surfaces engage simultaneously in spaced localized areas when the warped cover is positioned loosely over the frame opening. Fastening means located within the localized areas of engagement of these surfaces clamp the cover securely in place without disturbing the warp.
