Latest Patents

Qing Hai Xu holds a patent for a "Multi-gear synchro-moving riving knife system with quick release device." This invention teaches how to build a woodworking table saw where a splitter or riving knife moves in synchronization with the saw blade. The design incorporates an idle gear that engages in planetary circular action around a fixed quadrant gear, ensuring that any height adjustment or angle tilting of the saw blade results in the same movement of the splitter/riving knife. This maintains a constant linear difference, typically 5 mm, between the saw blade and the splitter/riving knife. Additionally, the invention features a spring pressure plate mechanism, along with lug bolts and a spring-loaded secure pin device, allowing for easy installation, changeover, and removal of the splitter/riving knife without the need for tools.
