Description: |
| There is no patent drawing. This patent improves on patent 95,824 by adding "pulverized carbonate of baryta or Witherite to the mixture of emery, sand, and oxide of zinc before adding the chloride of zinc, when making emery-wheels." Carbonate of baryta, or Witherite, is a barium carbonate mineral, and is found in Vermont among other places.The inventor manufactured emery wheels. He went bankrupt in 1873 or '74. The 1873 Boston Directory lists "Merrill E. C. emery-wheels, &c. 114 Elliot, house at West Charleston, Vt." According to the 1883-84 "Gazetteer and Business Directory of Lamoille and Orleans Counties, Vt", "The Vermont Emery Wheel Co., located at West Charleston, was organized in 1874. It is a stock company, with Charles Carpenter as treasurer and managing director. The business was originally established by E. C. Merrill, in 1870. About $15,000 to $20,000 worth of emery wheels are manufactured per year." |
