Mrs Potts sad iron

In 1871, Mary Florence Potts of Ottumwa, Iowa patented the "Mrs. Potts' sad iron (No.113,448). The invention is a detachable handle for pressing irons. Thus a person could heat a number of iron bodies on a stove, using each in turn with one handle. It was widely manufactured and licensed in the U.S. and Europe with advertising featuring her picture. The body of the iron was cast hollow and was later filled with an insulating material, such as plaster of Paris, cement or clay. Mrs. Potts claimed in her patent that this material held the heat longer so that more garments could be ironed without reheating the iron. Three irons, one handle and one stand were sold as a set. Mrs. Potts' iron is well known by antique dealers and collectors.
