Abstract
In accordance with one embodiment, a bowling ball weighing apparatus comprises a weight scale and a bowling ball support assembly. The apparatus comprises a ball support assembly and a weight scale. The ball support assembly has a cradle which holds the bowling ball and the assembly has weight supports. Whenever the scale is read, one of these weight supports is supported by the scale and another is supported apart from the scale. In a first orientation of the bowling ball with a first hemisphere of the ball closer to the weight support supported by the scale, a first scale reading is determined. Then in a second orientation with the first hemisphere of the ball farther from the weight support supported by the scale, a second scale reading is determined. Comparison of the two scale readings allows determination of the weight imbalance of the ball's two hemispheres. This weighing apparatus is able to use a single, readily available commercial scale, making it low in cost to produce, and the use of an electronic weight scale allows fast, accurate readings.
