Title: The Innovative Mind of Harry James Fruin
Introduction
Harry James Fruin, based in Staincross, England, is a notable inventor with two innovative patents under his name. His contributions to the field of mining technology have demonstrated significant advancements, particularly in haulage transmission systems and water jet applications in mining machinery.
Latest Patents
Fruin's latest invention is a **Mining Machine Haulage Transmission**. This system incorporates an overload protection arrangement featuring a torque sensing device that meticulously monitors the transmitted torque. If the torque exceeds a predetermined threshold, the system effectively decouples one or more clutches, disconnecting the transmission output from its input. This innovation allows for electrical output signals to control the clutches, ensuring operational efficiency and safety. Furthermore, an additional power source can be connected to operate the clutches, enhancing the control mechanism in situations of torque overload.
Another remarkable patent of Fruin is the **Mining Machine with Cam-Operated Water Jet Pump**. This device is designed to traverse mine faces and features a rotary drum equipped with liquid orifices to supply water under pressure. Each orifice generates a water jet with varying pressure, aimed at the material being mined during peak pressure moments. The operation involves reciprocal movement between numerous pistons and respective bores, facilitated by an eccentric bearing in the rotating drum. To augment the water jet cutting, this drum may also carry cutting picks, showcasing an innovative blend of mechanics and fluid dynamics.
