Abstract
Abstract A putting aid includes a base bar and an upright bar pivotally connected to the center of the base bar to be foldable into alignment with the base bar for storage in a golf bag and to be held in a position perpendicular to the base bar for use. Clips support the upright bar on the shaft of a putter, and a bubble level is on the base bar for leveling the base bar accurately horizontally. A pair of sighting bars are pivotally mounted at opposite ends of the base bar and extend to the upright bar where a scale extends upward from the base bar so that elevated inclination of the sighting bars can be read on the scale. A table on the upright bar above the scale is then used for computing lateral distance from a hole for aiming a putt, with the lateral distance being a function of the putt distance and the green inclination as measured by one of the sighting bars and the scale.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
204 words
A putting aid comprising: a. a base bar; b. an upright bar pivotally connected to a central region of said base bar to be foldable into parallel relation with said base bar; c. means for holding said upright bar in a position perpendicular with said base bar during use of said aid; d. clip means on said upright bar for attaching said upright bar to the shaft of a putter; e. a bubble level on said base bar for leveling said base bar accurately horizontally; f. a pair of sighting bars; g. means for pivotally mounting each of said sighting bars on respective opposite ends of said base bar; h. each of said sighting bars extending from said respective opposite ends of said base bar to the region of said upright bar; i. a scale extending upward from said base bar on said upright bar so that elevated inclinations of said sighting bars are readable on said scale; and j. a table arranged on said upright bar above said scale for computing lateral distance from a hole for aiming a putt, said lateral distance being a function of putt distance and green inclination as measured by one of said sighting bars and said scale.
