Attorney, Agent or FirmAbstractA fixture to facilitate measuring and adjusting the loft and lie angles of a golf club or iron comprises a guide having a plane indexing surface pivotally adjustable to various standard loft angles, and having upper and lower shoes for clamping the head of the club therebetween in predetermined alignment whereat the score lines on the club face are horizontal, the face is flush with the indexing surface, and the sole of the head is seated on the lower shoe at only two locations adjacent the rounded junctures respectively of the sole with the heel and toe of the head, the latter location being elevated with respect to the former. The upper shoe is movable parallel to the indexing surface toward the lower shoe in the clamping action, has a rounded cam engageable with only a mid-location of the top edge of the head for camming the head toward the indexing surface and lower shoe, and has limited universal lost motion for adjusting the cam to the angle of the top edge during the clamping action. A protractor selectively movable with respect to the club shaft has a loft angle indicator pivotal about a horizontal axis into parallelism with the shaft for indicating the deviation from a standard loft angle, and has a lie angle indicator pivotal on the loft indicator into parallelism with the shaft for indicating the lie angle.Field of SearchAngular measurement | |
