DEFINITION

Classification: 198/588

(under subclass 587) Apparatus including means for changing the length of the path over which the load is conveyed.

(1) Note. Included here are (a) conveyors movable relative to each other so that one conveyor can discharge the load at different points along the available path of load travel on the other conveyor, and (b) plural conveyors, at least one of which includes means for varying its conveying length (e.g., and endless belt conveyor having a belt storage loop that can be shortened while the length of the belt conveying reach is increased during operation of the conveyor, or an endless belt conveyor provided with means for facilitating the addition or removal of links or panel sections of its loop when the conveyor is not operating).

(2) Note. A vibratory conveyor is included here if it includes two platforms which successively carry the load, and which can be shifted relative to each other, while the conveyor is operating, to thereby change the length of the conveying path. This subclass does not include a vibratory conveyor having two platforms which successively carry the load, and which can only be shifted relative to each other

while the conveyor is not operating (e.g., a vibratory trough consisting of two sections that can be fixedly connected together by means of bolts, or the like, with different overlapping of adjacent end portions of said sections). See subclasses 752.1+.
