  • Patent number: 9586105
    Abstract: A golf club head having a high COR at its face center and a center of gravity located at a point close to the face and the sole is disclosed herein. In particular, the golf club head comprises a hollow body including a weight lip and face component, and the weight lip extends from the sole inside the body towards the face component without making contact with the face component. The golf club head preferably is a two-piece iron-type golf club head, and each piece is heat treated differently before being welded together to further optimize center of gravity location, ball speed, and COR distribution across the face.

  • Patent number: 7427043
    Abstract: A combination includes a family of cartridge drives (12) including a first cartridge drive and a second cartridge drive, and a family of cartridges (14) including a first cartridge and a second cartridge. The first cartridge drive includes a first protrusion pattern (32), and the second cartridge drive includes a second protrusion pattern (32) that is different than the first protrusion pattern (32). The first cartridge includes a first recess pattern (62) that receives the first protrusion pattern (32) thereby allowing full insertion of the first cartridge into the first cartridge drive. The second cartridge includes a second recess pattern (62) that receives the second protrusion pattern (32) thereby allowing full insertion of the second cartridge into the second cartridge drive. The second protrusion pattern (32) can impede full insertion of the first cartridge into the second cartridge drive.

  • Patent number: 6929208
    Abstract: A cartridge assembly (10) includes a cartridge (12) and a cartridge retainer (14). The cartridge (12) includes a reel (22) having a rotational axis (46) and a flange (48, 50). The cartridge (12) also includes a cartridge housing (16) that rotatably secures the reel (22). The cartridge housing includes one or more interior surfaces (19, 21). The reel (22) is adapted to tilt relative to the cartridge housing (16). The cartridge housing (16) includes a plurality of ribs (30) each having a chamfer (72). The ribs (30) can be disposed on an upper housing section (18) and/or a lower housing section (20) of the cartridge housing (16). The reel (22) has a contact tilt angle ?1 relative to the interior surface (19, 21), and at least one of the chamfers (72) has a chamfer angle ?2 relative to the interior surface (19, 21) that is substantially similar to the contact tilt angle ?1. The flange (48, 50) contacts the chamfer (72) so that the flange (48, 50) is substantially parallel with the chamfer (72).
