Abstract
A device for measuring the passage of a predetermined length of cloth at right angles to the needle of a sewing machine comprises a frame carrying an arm mounted about a shaft and urged resiliently towards the cloth by a spring adapted to put a pinion in contact with the cloth. A shaft carries a barrel in contact with a gear fixedly connected to the pinion, the barrel enclosing a spring. The barrel is connected to a terminal by a sliding contact and carries a pin which extends into an arcuate groove in a drum while passing through an arcuate aperture in a plate. Contact elements are disposed at one end of the groove and at one end of the arcuate aperture, the pin being able to move from one to the other of these contact elements. The contact elements press against the internal surface of a metallic ring carried by the drum, the external surface of this ring being connected to a second terminal by a sliding contact.
