Abstract
A speed setting device for an industrial sewing machine comprises a lever pivotally mounted at one end thereof on a stationary wall and adapted to be pivotally moved in response to the foot pedal of the sewing machine. An arm is pivotally mounted at one end to the stationary wall and operatively engaged with the lever so that they rotate in unison about respective pivot points thereof. The pivot point of the second member is between the lever pivot point and the engagement point between the lever and arm. Thereby, the arm is rotated through an angle greater than the angle through which the lever is rotated in response to the angular displacement of the foot pedal. An angular displacement sensor detects the angular displacement of the arm to generate a speed setting signal.
