Abstract: Providing visual cues to a golfer to instruct or remind the golfer as to aspects of better play. The visual cues are placed on a device which may be planted on a golf course to mark ball location on the golf course, so that the ball may be removed and subsequently replaced at the same location. The apparatus may comprise a circular pad bearing indicia which is visible from above and a spike which projects downwardly to engage the ground. An associated method combines the functions of marking ball location and receiving golfing instruction, using the novel apparatus.

Abstract: The specification discloses a bearing lubricating system including a shaft having two inner raceways formed therearound and a concentric bore formed in the shaft. Passageways communicate between the bore and the inboard portion of the inner raceways. Balls are provided having radii slightly less than the arc radii of the raceways. The bearing structure is completed by an outer ring having two outer raceways formed therein. The outer raceways in the outer ring are separated more than the separation between the inner raceways in the shaft such that the balls contact the inner and outer raceways at an angle to a plane perpendicular to the axis of the bearings. As a result, the balls contact the inner raceways on the outboard portion of the raceways to prevent the balls from contacting the opening of the passageways into the inner raceways. The bore formed in the shaft is threaded along its entire length and is loaded with a suitable lubricant.
