MUMBAI, India, April 17 -- Intellectual Property India has published a patent application (202641042231 A) filed by Minu Mary Joy; Joy Paul; and Lipin Paul, Ernakulam, Kerala, on April 2, for 'a system for manually driving a centrifugal pump using a gear-operated lever and belt transmission.'
Inventor(s) include Minu Mary Joy; Joy Paul; and Lipin Paul.
The application for the patent was published on April 17, under issue no. 16/2026.
According to the abstract released by the Intellectual Property India: "The invention relates to manual fluid-handling equipment featuring a hand-operated gear-driven belt-and-pulley system for powering a centrifugal water pump. A support frame with bearing bushings and a pillow-block bearing houses a lever assembly pivoted on a fulcrum pin. The lever hub carries a large driving spur gear that meshes with a small driven spur gear on an intermediate shaft. The intermediate shaft also supports a first pulley connected by a flexible V-belt to a second pulley keyed to the pump input shaft. During operation, reciprocation of the dual lever arms causes oscillation about the fulcrum, rotating the large spur gear. Through the gear ratio and belt-pulley transmission, the system multiplies input speed and efficiently transfers power to the pump shaft, enabling continuous high-speed water discharge without requiring electricity or fuel-powered systems."
