Abstract
Abstract This practice weight is basically a disk of molded rubber based plastic material having a circular rim in which a metal ring is encased concentrically with the disk, the disk having a center hole and radial slits extending therefrom to the rim portion to provide resilient friction tabs or fingers that are yieldable in both directions permitting slipping the practice weight on over the handle grip down to the head for practice swings and later removal of the practice weight in the reverse direction, the tabs or fingers engaging the hosel firmly enough to hold the practice weight in place properly during the practice swings. An elongated radially outwardly extending rubber based plastic tab can be molded in one piece with the disk ending in an outwardly tapered pointed wedge, this tab being long enough to permit bending it into a semicircle behind the head after the practice weight is in place at or adjacent the head on an iron, when the pointed end of the wedge is forced through the center hole of the disk upwardly far enough to jam it on the hosel of the club and thereby fasten the practice weight securely against slipping down past the heel of the club head in practice swings and coming into contact with the ground.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
152 words
For use on a golf club having a shaft and a head thereon, a practice swing weight attachment comprising a metal weight ring of a diameter that is small in relation to the length dimension of the head but large in relation to the diameter of the shaft and adapted to be assembled on the lower end of the shaft over its upper end, and means in substantially coplanar relationship to said ring and extending radially inwardly relative to the ring for supporting said ring in a fixed substantiAlly concentric relationship to said shaft adjacent the club head, said means being in the form of flexible and resilient fingers that are yieldable to permit passing the device over the upper end of the shaft, the fingers thereafter springing back to substantially coplanar relationship to said ring and frictionally gripping said shaft to resist axial displacement from a set position on said shaft.
Claim 2
Dependent Claim
152 words
For use on a golf club having a shaft and a head thereon, a practice swing weight attachment comprising a metal weight ring of a diameter that is small in relation to the length dimension of the head but large in relation to the diameter of the shaft and adapted to be assembled on the lower end of the shaft over its upper end, and means in substantially coplanar relationship to said ring and extending radially inwardly relative to the ring for supporting said ring in a fixed substantiAlly concentric relationship to said shaft adjacent the club head, said means being in the form of flexible and resilient fingers that are yieldable to permit passing the device over the upper end of the shaft, the fingers thereafter springing back to substantially coplanar relationship to said ring and frictionally gripping said shaft to resist axial displacement from a set position on said shaft.

Claim 6
Dependent Claim
119 words
A golf practice swing attachment as set forth in claim 1 wherein the last-mentioned means comprises a rubberlike disk having a rim portion in which the ring is encased in substantially concentric relationship to a center hole provided in the disk through which the shaft of the club is entered, said disk having a plurality of substantially radial slits provided therein extending outwardly from the center hole thereby defining substantially radial tabs or fingers that are resilient and yieldable in either direction, and the center hole being small in relation to the diameter of the shaft so that said tabs or fingers provide friction grips to hold said practice swing weight in operative relationship to the shaft and head.
Claim 7
Dependent Claim
106 words
For use on a golf club having a shaft and a head thereon, a practice swing weight attachment comprising a metal weight ring and a rubberlike disk having a rim portion in which the ring is encased in substantially concentric relationship to a center hole provided in the disk through which the shaft of the club is entered, said rim having integral therewith an outwardly extending flexible tab that is adapted to be flexed inwardly and is long enough so that its outer end portion can be thrust into the center hole to help secure the practice swing weight in its operative position on the club.
Claim 8
Dependent Claim
106 words
For use on a golf club having a shaft and a head thereon, a practice swing weight attachment comprising a metal weight ring and a rubberlike disk having a rim portion in which the ring is encased in substantially concentric relationship to a center hole provided in the disk through which the shaft of the club is entered, said rim having integral therewith an outwardly extending flexible tab that is adapted to be flexed inwardly and is long enough so that its outer end portion can be thrust into the center hole to help secure the practice swing weight in its operative position on the club.
Claim 9
Dependent Claim
33 words
A golf practice swing attachment as set forth in claim 6, wherein the outer flexible tab has an enlarged wedge provided on the outer end thereof for wedging engagement in the center hole.
Claim 10
Dependent Claim
128 words
A golf practice swing attachment as set forth in claim 6 wherein said disk has a plurality of substantially radial slits provided therein extending outwardly from the center hole thereby defining substantially radial tabs that are resilient and yieldable in either direction, and the center hole being small in relation to the diameter of the shaft so that said tabs provide friction grips to hold said practice swing weight in operative relationship to the shaft and head, the flexible outer tab being thrust into the center hole between the shaft and the inner end of at least one of the other tabs, the outer tab being adapted to be cut off next to the disk when the practice swing weight attachment is to be used only on woods.
