摘要： An electric sewing machine is provided on which it is feasible conveniently to perform variously programmed sewing, for example, continuous sewing for forming a desired zigzag seam and non-ravel seams at the start and the end of the zigzag seam. The sewing machine comprises:At least one regulator for influencing the operation of stitch forming instrumentalities thereof, i.e., an amplitude regulator and/or a feed regulator;A manual knob operatively connected to the regulator for setting the regulator at a desired setting;A single manually operable member shiftable among three specific positions,A first one for stopping the machine,A second one for running the machine under the operation of the knob to form the desired (e.g., zigzag) seam, andA third one for running the machine out of the operation of the knob to form a predetermined (e.g., non-ravel) seam.

摘要： A sewing machine comprising a frame, including a base, a free lower arm having a work supporting surface, a base plate, and a sub-table device for converting the sewing machine from a free arm type to a flat bed type and vice versa. The sub-table device includes a connection plate and a support plate, said connection plate being hinged to the base plate in a manner to be turned between a fallen position, in which the connection plate extends horizontally from and frontwards of the end of the base plate, and a raised position in which said connection plate is set upright on the end of the base plate, and said support plate is hinged to said connection plate in a manner to be movable between a lower position in which same is folded in superposed relation to the connection plate which assumes the fallen position and an upper position in which said support plate rises upright in side by side relation to said lower arm, with its top surface substantially continuous with the work supporting surface of the free lower arm.
