ABSTRACT:
Spheres are sequentially released into a pipeline from a sphere storage barrel in response to the opening and closing of a valve closure member by means of a sphere launching apparatus. The apparatus has a releasing means, pivotable about a first axis, for engaging the valve closure member and a catcher, pivotable about a second axis, for releasably engaging the spheres as well as an actuating link connecting the releasing means with the catcher.
In response to the opening and closing of the valve closure member, the catcher is angularly pivoted into and out of engagement with successive spheres at a first rate, upon angular pivoting of the releasing means at a second rate less than the first rate, to sequentially release spheres and to allow the valve closure member to substantially close before releasing the next sphere.
