David Fisher's name doesn't come up very often, but he is responsible for two devices that we take for granted, the joiner's clamp and furniture casters.
The joiner's clamp made the work of furniture workers easier and more productive. He patented the device on April 20, 1875. It was used to apply balanced pressure, binding together pieces of wood, and allowing the furniture maker to continue working on the furniture, thus saving time and enhancing productivity.
Fisher then went on to invent furniture casters, patenting his invention in March, 1876. This made moving heavy pieces of furniture much easier. The free turning wheel allowed one person to safely and efficiently move furniture around, drastically cutting down on the labor required for this task.
