label: Description
content: This is a patent model for a tile-making machine, patented by Pierre Hervier of New York City, NY on November 10, 1874. The machine was created to simplify the tile removal process and enhance the performance of molds. It consists of a two-part mold that is connected by a hinge – the upper section swings open and allows for easy tile extraction. Both the die and the mold faces are covered with plaster of Paris, which absorbs moisture from the clay to prevent sticking to ensure a clean release of the formed tile. The tile mold slides into position on guide grooves and is held in place by a plate and stop mechanism to align correctly with the die before compression—resulting in more efficient, non-stick tile production.
