A rod connected to the pin serves to raise and lower the upper ends of tlio two con-necting rods, and in doing so the field magnets are separated or brought together, as the casemay be. When used in connection with a sewing machine, the motor is secured to the underside of the table in an inverteil position, and the regulating lever connected to the this position the field magnets fall apart of their own weight and the machine does notwork. It is only when the treadle is pressed and the magnets are brought together that mo-tion is obtained. It is evident that by varying the distance between the armature and themagnets any desired speed can be obtained for fast or slow work. The armature ehaft is.
