Latest Patents

One of his latest inventions is the Self-centering clamp. This clamping device is designed to ensure that a workpiece fixed between the jaws of the clamp is self-centered. It achieves this by coupling the jaws to a pair of linkages that rotate through the same angle, allowing for linear movement across the surface of the device. The clamping device utilizes a coupled linkage, such as a 180° bell crank, in combination with slots for retaining opposing jaws. This design provides a fast and accurate self-centering arrangement. Additionally, the clamping device can be located within a hollow workpiece and controlled to move the jaws outward, engaging the inner surface in a self-aligned configuration.

Another significant patent is the Pipe cutting apparatus and method of using the same. This apparatus includes a housing with a central aperture for holding the pipe in a fixed position. A rotatable collar is mounted on the outer surface of the fixed housing, with a cutting head attached to the collar. The cutting head is designed to translate forward and backward, allowing for complex cuts without moving the pipe. Various cutting tools, such as laser and plasma, can be attached to the cutting head, enabling a range of tasks including cutting through the pipe, inscribing on the surface, and forming through-holes.
