Weighted golf irons and method of making same

An improved weighted golf irons and method of making same comprising adding a divider to a cavity in the iron, the divider dimensioned to be contained within and traverse the cavity walls, and providing means for anchoring the divider to the walls.

golf ironss are normally made of cast steel. Frequently additional weights are inlaid to provide a sweet spot which improves the performance of the club.

Providing such a “sweet spot” has been known to include casting the iron head with a cavity that is filled with weights. Usually a plurality of small weights are used in order to weight each head carefully for the particular user.

Having determined the number and position of the weights, the cavity is filled with a material such as epoxy. It has been known to add a decorative epoxy layer to the cavity to add glamour to the club.

Golf clubs can be subjected to extremes of temperature. In particular, this may occur when the clubs are carried on an airplane. As a result of extreme temperature changes, upon occasion an epoxy filling may separate somewhat from the wall of a cavity. The present inventor has discovered that the addition of a divider, and more particularly, a metal bar dividing the cavity substantially into two parts and anchored inside the cavity to the cavity walls, significantly reduces any problem with the epoxy separating from the walls due to use, wear and the environment.

In a golf irons having a cavity filled with a plurality of weights and epoxy, an improvement is disclosed comprising a divider dimensioned to be contained within and to traverse the cavity from wall to wall, and including means for attaching the divider to the walls of the cavity.

In preferred embodiments the divider comprises a metal bar. Attaching means can comprise one or more slots in portions of the cavity wall, the slots dimensioned to receive an end of the bar. A 3/32 inch diameter metal bar has been determined to comprise an adequate bar.

In preparing the golf irons, the head is prepared with a cavity in the rear of the iron. The divider may then be attached within the cavity. In a preferred embodiment the divider is attached by slipping the ends of a metal bar into two opposing slots provided in wall portions of the cavity. The cavity is then filled by curing resin over weights added to the cavity .

Applicant has previously invented a weighted inlaid golf irons and method of making same. The disclosure of that patent is hereby incorporated by reference.

It shows a golf irons prepared substantially according to the now existing art. A cavity is shown on the rear of the iron. The cavity is filled with small weights, preferably of a size similar to B–B’s. A standard number 8 lead shot was determined to be adequate. In most cases between 219 grams and 229 grams of weight is added to the club.
