DEFINITION

Classification: 198/638

(under subclass 618) Apparatus which projects material to be conveyed by, first exerting a force on said material to move the same, and then causing said force to be released from said material, whereby said material will be projected and continue to move unsupported, in a trajectory, over a horizontal distance.
