Abstract
A horizontal ball return mechanism for propelling a bowling ball from one end of a bowling alley to the other includes a generally horizontal track with compression and decompression sections and a generally flat horizontal section therebetween. Two pulleys and an endless belt move a bowling ball along the track. The compression, decompression and a flat horizontal section lift a bowling ball upwardly against the belt, maintain the belt under compression as the ball moves along the generally flat section and lowers the ball before it passes under a second of the pulleys.
