"Lochman’s Rotary Type Cork Press was invented by C.A. Lochman in 1867, and patented by the Enterprise Manufacturing Company the same year. It is called Lochman’s Cork Press and was made of cast iron with a black japanned finish and came in two sizes. The smaller model has a wheel of ~3.5 inches in diameter and the larger size wheel is ~4.5 inches." -Richardson, The Pill Rollers
