Abstract
A training device useful with a putter having a head and a shaft extending from the head has a sight line, which may be delineated by a taut string, and two rails for guiding the shaft as the putter is swung through a limited range defined by the rails. The limited range includes an intermediate position, in which the head of the putter is positioned in a lowermost position, a subrange of back-swing positions, in which the head of the putter is raised from the lowermost position, and a subrange of follow-through positions, in which the head is raised from the lowermost position. Each rail has a guiding surface. The rails are adapted to be adjustably curved into any of various configurations such that the shaft when guided along the guiding surfaces is positioned in a position farthest from the sight line when the putter is positioned in the intermediate position with the head positioned in the lowermost position and such that the shaft is positioned in positions closer to the sight line when the putter is swung through either subrange with the head raised from the lowermost position. The rails are arranged such that an imaginary line tangent to the guiding surfaces of the rails, in an imaginary plane intersecting the rails at any position within the limited range, is inclined approximately at a constant inclination relative to a horizontal plane. The rails are adjustable so as to adjust the constant inclination.

A device and method for improving the putting of a golf ball is described herein. The instructional device employs a sighting member and a shaft guide to assist in aligning and stroking a golf putt. The device is configured such that a golfer or instructor may develop each putting skill independently or in combination with the other skills. The device comprises two stands, set apart, with the sighting member attached to the top of each stand. A square face indicator may be positioned perpendicular to the sighting member, and the shaft guide may couple to a side of the stands. A method for improving the putting of a golf ball is also described herein, where the method addresses finding and verifying a sight line that extends from a golf ball to a desired target, aligning a golf putter face squarely to said sight line, and moving a putter shaft parallel to said sight line.

The lower portion will be located on the desired surface for putting and the upper portion will be elevated from this lower portion. The lower portion acts as a supports and supports the upper portion which includes a horizontal bar member. This horizontal bar member acts as a guide. Thus for utilization, the user places a golf ball in front of the horizontal bar member. The club's head is placed behind the ball and the shaft will rest against the horizontal bar. This will force the shaft to move in a straight and forward position thus improving on the golfer's swing and putting capabilities.
