Perimeter weighted golf club head
First Claim
1. A perimeter weighted iron type golf club head comprising:
- a) a metallic body characterized by, a hosel for attaching to a shaft, a heel angularly contiguous with the hosel, an upper top ridge and juxtapositioned sole, both interfacing with the heel, a toe connected to the top ridge and sole, this combination defining a front striking face and a rear wall,b) said body rear wall having an integral mating surface around an outside edge of the heel, top ridge, toe and sole, said body mating surface formed of a recessed channel having a pair of outwardly extending legs.c) a mating peripheral weighted skirt of a dissimilar metal heavier in equivalent mass weight than the body base metal and of a peripheral shape conforming to the mating surface of the rear wall, andd) fastening means for joining the weighted skirt to the mating surface of the body rear wall, thereby locating the heads center of gravity rearward from the front striking face and said fastening means having each leg of the recessed channel bent inwardly forming a swaging rim captivating the skirt with parent metal of the mating surface channel.

Abstract
A perimeter weighted golf club head which has a body (40) defining a hosel (42), a heel (44), a ridge (46) of top (74), a sole (48) and toe (50). The combination forming a front face (52) and rear wall (54). The rear wall contains an integral mating surface (56) around which a weighted skirt (60) is attached. The skirt completely surrounds the periphery of the front face of the body and is of a metal heavier in equivalent mass weight than the body base material. The skirt material includes but is not limited to tungsten, depleted uranium, lead and their alloys in the base state or sintered together. The skirt is attached to its mating surface by brazing, swaging or using structural adhesives. A second embodiment includes a hollow (66) around the perimeter in which molten lead is poured. A third embodiment utilizes a segmented weighted skirt in a number of pieces to customize the head to the golfer. Both iron-type and wood type golf club heads are included in this invention.
