Origins of the Liquid Filled Golf Ball
If you follow the Golf-Patents blog then you probably realize that I was fascinated by a recent Callaway ball patent (just see my prior posts here and here). The Callaway invention is directed to internal structures in the ball that divert liquid as the ball spins to control the spin of the ball.
The Callaway patent inspired some research into the origins of liquid filled golf balls (and there have been many!). The earliest US disclosure of a liquid filled golf ball is found in USPN 715295 titled “Playing Ball,” which was filed in 1902. What an amazing century old golf ball design. Check it out.
