Abstract
A sewing machine provided with a set of pattern generating cams is also provided with a user-operated multi-setting pattern selector dial. When the selector dial is turned to a particular setting, to thereby cause the pattern generating cams to generate the corresponding pattern, a first mechanism automatically selects a respective feed pitch (amount of cloth feed per needle penetration), appropriate for the type of pattern selected. Accordingly, the user is not troubled to determine, by trial or error or otherwise, what feed pitch values would be clearly unsuitable for the selected pattern, and is instead automatically presented with a standard feed pitch value appropriate for the selected pattern. However, the user can also turn a second selector dial to increase the automatically selected standard feed pitch value by an amount up to 50% thereof, or alternatively to decrease the automatically selected feed pitch value by an amount up to 50% thereof, for example to take into account unusual thinness or thickness of the cloth being sewn on.
