Did you know your Sewing Machine Treadle was invented by Allen Bradley In 1925?
This is depicted amongst the one hundred innovations featured in the amazing “Wall of Glass” mosaic commissioned by Allen Bradley in 1956. AB developed the first SEWING MACHINE Treadle control with Lynde Bradley’s carbon pile rheostat. It was used with sewing machine motors, for stepless control. It operated by applying force on the top of the foot pedal. This changed the resistance and varied the speed of the motor and your sewing stitch! Photo: lillian Sizemore
