DEFINITION

Classification: 198/633

(under subclass 618) Apparatus wherein the conveyor section has either (a) a means associated therewith which in its operative position presents a nonload-supporting means which may be engaged by, or engages, the load as it is moved by said section to stop, slow or cause the load to be manipulated or deflected from the path of movement imparted only by said conveyor section; or (b) a means movable to a position where it will cause the load moved only by the conveyor section to be removed and supported from the influence of said section for the purpose of stopping the motion of the load, and which then may subsequently return the load to the conveyor section for continued conveyance thereby.

(1) Note. This subclass includes those patents claiming a single conveyor section and having a load deflector means which is movable from and to operative position, or is

adjustable to various operative positions. When it is clear from the claimed disclosure that the function of the deflector is to increase or decrease the number of streams or to ultimately select the load destination, etc., see subclasses above., e.g., 348+, 418+, 434+. See (3) Note for subclass 434.

(2) Note. This subclass also includes patents having means which may be placed in the path of the conveyed load to check the load against movement counter to its intended direction.

SEE OR SEARCH THIS CLASS, SUBCLASS:

456+, for a conveyor system having means to laterally shift the load on one or more of the conveying elements of the system.

530+, for gravity conveyors combined with power-driven conveyors and having gate means to stop the movement of the load thereon. 534, for flow-restricting structure in a system comprising a gravity conveyor and a power-driven conveyor, which structure may be a means to change the movement of the load for this or an indented subclass.

599, for a system of plural conveyors combined with a passive member that deflects a load from the travel direction imparted thereto by one of said conveyors.

836, for endless conveyor sections having passive load retainer means associated therewith which simply holds the load against falling from the belt or moving relative to the belt.
