Abstract: A method for applying a putter alignment indicator to a putter to aid in aligning the putter during a putting stroke. The method includes providing a substantially planar alignment surface and having a golfer, while standing in the golfer's normal putting stance, place the striking surface of the putter head against the substantially planar alignment surface. A light source directs a beam of light onto the elongated shaft to create a shadow on the heel portion of the putter head. The position of the light source is adjusted until the first edge and the second edge of the shadow, as viewed by the golfer when standing in the golfer's normal putting stance, appear adjacent to or directly behind the shaft. An alignment indicator is applied to the putter head adjacent to at least one edge of the shadow.

The body and cap define a void and the center of gravity of the putter head is within the void.

Abstract: There is disclosed a golf club such as a putter and in one embodiment an attachment for the same. The club head has at least one striking face, a rear face and side faces or edges defining a body of a predetermined thickness to which a shaft is attached. Within the body of the head there is provided a recess in a form which opens into the rear face of the head or as a closed aperture completely defined within the body which is of marginally greater dimensions than, and adapted to receive an object such as a conventionally sized golf ball. The recess or aperture can be disposed of substantially centrally of the head behind the striking face of the club head so that the “sweet spot” on the striking face can be substantially centrally disposed of said recess or aperture. Ideal toe-heel weight distribution can be achieved in this manner.

Abstract: The present invention provides a golf putter having a shaft attached to the club face of the head by a hosel. The hosel is attached to the face with the bottom of the hosel flush with the bottom of the head and the bottom of the face. The hosel maintains the face and the shaft in spaced parallel planes to define a space between the face and the shaft. The hosel may have a circular cross sectional shape or another cross sectional shape that allows the golfer to better see the bottom of the hosel. The present invention provides a golf putter that allows the golfer to clearly see the bottom of the hosel and, thus, gauge the distance to the ground and the bottom of the golf putter so that the golfer can know how far he may come up in the stroke to apply a top spin to the golf ball without topping the ball and allows the golfer to apply a pulling stroke rather than a pushing stroke.

Abstract: A new golf swing training device for providing a visual frame of reference for correctly completing the swing of a golf club having the training device installed thereon.

The inventive device includes a training device comprising a guidance device for removably attaching to a golf club, and a mounting means for removably mounting the guidance device to the golf club. The golf club is of the type having a shaft and a club head with a face.

Abstract: A novel and unique golf club, particularly a putter, is disclosed which has an effective structure for attaching the shaft of the club to the club head, such that the result is a self-compensating putter and consistently accurate putts. In a preferred embodiment, a golf club is provided which comprises a shaft and a club head having a front face. The club head has a length along which the front face extends. Advantageously, the shaft is attached to the club head at two discrete mounting locations along the length of the club head, which results in a consistently stable and comfortable swing.

Abstract: Golf club sight alignment device comprising a plurality of rectilinear slots or grooves disposed in the top surface of the club head from the face to the back of the club head at predetermined angles of incidence to the bottom of the club head and having predetermined depth and width such that one holding the golf club can correctly position the golf club by visually perceiving the light reflected from the bottoms of the grooves or slots at maximum visual acuity to ascertain when the club is correctly positioned for striking a golf ball.

Abstract: The present invention provides for a "rifle sighting system" on the top surface of the clubhead which allows the golfer at the address position to align the ball where the center marker on the clubface will be at impact. This system factors in the effect the downward bowing of the shaft on the forward swing has on the center of the clubface's position at impact. It also factors in the parallax visual error the golfer experiences as he tries to align the center of the clubface to the ball.

Abstract: A sports swing exercise device composed of a weight attached to a shaft by means of a spring.
