  • Patent number: 5495817
    Abstract: This invention is a dual foot pedal control for a sewing machine consisting of a foot activated tiltable pedal assembly mounted on a base member which is attached to a stabilizing mat. The stabilizing mat is positioned between the legs of a sewing machine table, on which a sewing machine is mounted. The tiltable pedal assembly is connected by rod to a sewing machine control arm which activates the sewing machine. In addition, the sewing machine is speed controlled by the counter-clockwise pressure on the pedal assembly which is transmitted by rod to the sewing machine control arm. The pedal assembly, when foot-tilted clockwise, activates an air control valve which directs compressed air to an air cylinder which is connected to and opens the presser foot of the sewing machine. When tilted counter-clockwise the air control valve dissipates air to the air cylinder allowing the presser foot to lower and clamp the material to be sewn.
