A sphere launching apparatus for selectively admitting spheres into a pipeline and comprising an angularly disposed support or track for storing a plurality of the spheres thereon, an access port at one end of the track for receiving the spheres therethrough for disposition onto the track, a discharge port at the opposite end of the track for discharging the spheres therefrom and injecting the spheres into the pipeline, the support member being interposed between the access port and discharge port for supporting the spheres in two parallel but offset substantially sequential relationship upon the track, and a release mechanism extending into the proximity of the support or track for alternate engagement with the leading sphere of each of the two parallel sequences thereof for releasing a single sphere at a time for passage through the discharge port for injection into the pipeline.
