Abstract

In a putter, at least one adjustable weight is provided which can be moved to different positions longitudinally along the putter head. The putter head is provided with a open channel with closed ends. The weight is slidably mounted within said outer chamber with bolts extending through a slot into a slide within the channel, and the bolt is adapted to be screw tightened into said slide to hold said weight in position. A vibration damping plate is disposed between the weight and the putter head. The front face of the putter is provided parallel vertical grooves defined in the front face, and the grooves are separated by flat lands between The grooves are arcuate in cross section so that the sidewalls of the groove slope is at an angle substantially less that perpendicular to the lands.

Claims

1. A putter comprising a putter head and a shaft fixed to said putter head,

said putter head defining a hollow channel extending longitudinally in said putter head,

a slot defined in said putter head in communication with said channel and extending parallel to said channel,

said putter head also defining an open outer chamber extending longitudinally in said putter head and parallel to said channel,

said slot providing an elongate opening between said channel and said chamber and having a width narrower than that of said channel and said chamber;

a weight slidably mounted within said outer chamber with a bolt extending through said slot between a slide within said channel and said weight, said bolt being adapted to be screw tightened to hold said weight in position.

2. A putter as recited in claim 1, wherein said outer chamber has closed rounded ends.

3. A putter as recited in claim 2, wherein said outer chamber has a depth at least as great as the width of the weight whereby the weight is mounted completely within the outer chamber.

4. A putter as recited in claim 1, further comprising a vibration damping plate defining said slot and sandwiched between said weight and said slide.

5. A putter as recited in claim 1, wherein said hollow channel has a rectangular cross section and said slide has a rectangular cross section and at least one rounded end.

6. A putter as recited in claim 1, wherein a plurality of weights are mounted in said putter head in a manner permitting the position of said weights to be adjusted along the length of said putter head.

7. A putter comprising a putter head, said putter head defining a hollow channel extending longitudinally in said putter head, a slot defined in said putter head communicating with said channel and extending parallel to said channel, a weight mounted on said putter head in a manner permitting the position of said weight to be slid to different positions along the length of said putter head, said weight being mounted on said putter head by a bolt extending through said slot between said weight and a slide within said channel and a plate made of vibration damping material sandwiched between said weight and said slide.

8. A putter a recited in claim 7, wherein a plurality of weights are mounted in said putter head in a manner permitting the position of said weights to be slid along the length of said putter head, said plate of vibration damping material being sandwiched between said weights and slide within said channel.

9. A putter as recited in claim 8, wherein said weights are held in position against said vibration damping plate by screw tightened bolts.

10. A putter comprising a putter head, a shaft fixed to said putter head, parallel vertical grooves defined in a front face of said putter head, said grooves being separated by flat lands between said grooves, said grooves being arcuate in cross section and being shaped so that the sidewalls of said grooves adjacent to said lands slope at an angle substantially less that perpendicular to said lands.
