MUMBAI, India, Jan. 23 -- Intellectual Property India has published a patent application (202521045338 A) filed by Saurabh Harishchand Gupta, Pune, Maharashtra, on May 10, 2025, for 'pneumatic gear shifter.'
Inventor(s) include Shubhangi Manwatkar; Sushil B Chopade; Vishal Abhiman Meshram; Siddheshwar Suresh Shirbhate; Amit Narwade; and Sagar Uttamrao Chirade.
The application for the patent was published on Jan. 23, under issue no. 04/2026.
According to the abstract released by the Intellectual Property India: "In pneumatic gear shifter, a gear shifter mechanism is designed and applied to achieve the variable speed required for the casting core of the work piece as the cross section of the work piece is varying and to make the shifting process faster and less destructible for the operator. The new device must be reliable, with small dimensions, low construction and maintenance cost. This project aims to improve gear shifting process using devices as : a manual two speed gear box, two pneumatic double acting cylinders, two pneumatic two position five ways directional control valves, an electrical motor, a belt, two pulleys, limit switches, push buttons, bulbs, a table (holder) and power supply. According to suggested gear shifting method the operator can select the transmission gear ratio without taking much effort. Using this method variable speed can be obtained on the vertical drilling machine and it leaves to the operator the excitement of choosing the shifting moment without much effort. By using pneumatic gear shifter, cycle time decreases and the production rate increases."
