  • Patent number: 9495827
    Abstract: A reel assembly for a gaming machine includes an inner drive ring defining an annular inner rim, an outer ring, and a support substrate. The outer ring is spaced from and coaxially positioned relative to the inner drive ring, and the outer ring defines an annular outer rim. The support substrate has opposing side edges each coupled to a different one of the annular inner rim and the annular outer rim. The support substrate extends substantially unsupported between the annular inner rim and the annular outer rim in a substantially continuous manner maintaining the annular inner rim spaced from the annular out rim.
    Type: Grant

  • Patent number: 9361751
    Abstract: A reel assembly for a gaming machine includes a central hub and a clip. The central hub defines an opening through an axial center of the central hub and includes two enclosed channels each positioned on an opposite side of the opening. Each of the two enclosed channels has an open end facing the opening. The clip includes a U-shaped main body and two opposing flanges. The U-shaped main body has opposing ends. The two opposing flanges each extend away from a different one of the opposing ends of the U-shaped main body. Each of the two opposing flanges of the clip fits through the open end of a different one of the two enclosed channels such that the clip is linearly slidable between the two enclosed channels while each of the two opposing flanges remains at least partially maintained with the corresponding different one of the two enclosed channels.
