Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
271 words
In article conveying and orienting apparatus for articles moved from a common feed path selectively into either of a pair of separate paths, the improvement comprising: a feed conveyor defining a plane of article movement and operative to move articles in spaced apart relation along a path ending at a discharge end; a pair of article receiving roller conveyors defining planes of article movement and having article receiving ends adjacent each other and adjacent said feed conveyor discharge end, said pair of article receiving roller conveyors being on opposite sides of an axis substantially centered with said feed conveyor path; an article steering wheel located in the article receiving end of each of said article receiving roller conveyors, each steering wheel being oppositely angularly oriented and movable to have the periphery thereof project above the plane of article movement from said feed conveyor to an article receiving roller conveyor to engage and direct articles toward the opposite one of said article receiving roller conveyors and initiating a turning response in the articles; means operably mounting said steering wheels such that the periphery of only one at a time is above the plane of said paths of article conveyance for the purpose of engaging and directing the articles onto an article receiving roller conveyor; and means beyond each of said steering wheels in the direction of article movement and operably disposed in said pair of article receiving roller conveyors to be engaged by articles directed into said article receiving roller conveyors and continue a change in the turning response of such articles to change the orientation from that on said feed conveyor.
Claim 2
Dependent Claim

In article conveying and orienting apparatus for articles moved from a common feed path selectively into either of a pair of separate paths, the improvement comprising: a feed conveyor defining a plane of article movement and operative to move articles in spaced apart relation along a path ending at a discharge end; a pair of article receiving roller conveyors defining planes of article movement and having article receiving ends adjacent each other and adjacent said feed conveyor discharge end, said pair of article receiving roller conveyors being on opposite sides of an axis substantially centered with said feed conveyor path; an article steering wheel located in the article receiving end of each of said article receiving roller conveyors, each steering wheel being oppositely angularly oriented and movable to have the periphery thereof project above the plane of article movement from said feed conveyor to an article receiving roller conveyor to engage and direct articles toward the opposite one of said article receiving roller conveyors and initiating a turning response in the articles; means operably mounting said steering wheels such that the periphery of only one at a time is above the plane of said paths of article conveyance for the purpose of engaging and directing the articles onto an article receiving roller conveyor; and means beyond each of said steering wheels in the direction of article movement and operably disposed in said pair of article receiving roller conveyors to be engaged by articles directed into said article receiving roller conveyors and continue a change in the turning response of such articles to change the orientation from that on said feed conveyor.
Claim 3
Dependent Claim
55 words
The apparatus of claim 1, wherein said steering wheels have a peripheral speed faster than said feed conveyor to accelerate each article, and said means to effect a change in the orientation of accelerated articles comprise freely rotatable rollers having axes of rotation at angles to the path of article movement in said separate paths.
Claim 4
Dependent Claim
31 words
The apparatus of claim 1, wherein said means beyond each of said steering wheels is adjustable between positions ineffective to change the orientation of articles and positions effective to do so.
Claim 5
Dependent Claim
50 words
The apparatus of claim 2, wherein said means beyond each of said steering wheels is movable to project above the plane of article movement whereby to elevate a portion of an article during accelerated movement and allow the momentum of the article free play to effect the change of orientation.
Claim 6
Dependent Claim
45 words
The apparatus of claim 2, wherein said freely rotatable rollers have axes of rotation at approximately 40° to the rollers in said article receiving roller conveyors, and said steering wheels have axes of rotation different from said first mentioned axes for said freely rotatable rollers.
