Abstract
A bowling alley having at least one elongated bowling ball runway, at least one downwardly offset concave gutter sidewisely depending from the runway, and at least one upwardly offset partition bar sidewisely depending from the opposite side edge of the gutter. A first wear-resistant semi-rigid protecting capping removably covers the upper portion of the partition bar. A second wear-resistant flexible protecting lining removably covers the top face of the gutter. Each of the capping and lining further has lengthwise ridges, whereby should the bowling ball engage the gutter or the bar, the ridges will bias the bowling ball travel in a path parallel to the elongated runway while prolonging the useful lifetime of the bowling alley. The cappings and linings also decrease the noise produced by the bowling balls.
