ABSTRACT:
The machine housing of a sewing machine is divided into a bed part provided with a hollow standard and an arm part which overhangs the flat horizontal face of the machine bed part. The machine arm part is connected to the upper end of the standard by a number of fastening bolts. A reamer bolt is first inserted into the upper end of the standard through the bottom of the bed part to provisionally connect the arm part to the standard, and then an eccentric pin inserted into respective bores provided in both parts of the housing is rotated to turn the machine arm part around the reamer bolt with respect to the machine bed part. After the arm part has been adjusted with the flat face of the bed part both parts are fastened to each other by fastening bolts.
