Accordion-arm spinning wheel consists of two vertical wooden uprights that hold two horizontal rails. A diagonal board goes from the lower rail through the right-hand upright. At the top of it is a solid wooden drive wheel and to the left is the accelerating wheel that is the same size. A wooden frame that can contract or expand is attached to the upper rail with the spindle unit on the last section of the frame. A foot pedal and a footman connect to a rod on the frame.
