Abstract
Abstract A corner conveyor for transferring articles between two endless conveyors, which generally extend at right angles to each other. The conveyor includes a pair of endless chains journaled around sprockets mounted on a pair of shafts which generally extend at right angles to each other. Upper and lower, nonparallel, curvilinear, guides are provided for guiding the upper and lower runs respectively, of each endless chain. The curvature of the lower guide is greater than that of the upper guide.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
66 words
A conveyor comprising: endless conveyor member means for conveying articles between angularly extending conveyors and including upper and lower runs; and vertically spaced upper and lower curvilinear guide means disposed out of vertical alignment for guiding said upper and lower runs, respectively, in different curvilinear paths between said angularly extending conveyors, the curvature of said lower run being greater than the curvature of said upper run.
Claim 2
Dependent Claim
66 words
A conveyor comprising: endless conveyor member means for conveying articles between angularly extending conveyors and including upper and lower runs; and vertically spaced upper and lower curvilinear guide means disposed out of vertical alignment for guiding said upper and lower runs, respectively, in different curvilinear paths between said angularly extending conveyors, the curvature of said lower run being greater than the curvature of said upper run.
Claim 3
Dependent Claim
32 words
A conveyor as set forth in claim 1 wherein said endless member means includes endless chains trained around sprockets mounted on generally horizontally extending shafts which extend angularly relative to each other.
Claim 4
Dependent Claim
32 words
The conveyor of claim 2 incLuding means for driving said endless chains at different linear velocities so that the orientation of the article relative to its path of travel remains substantially constant.
Claim 5
Dependent Claim
41 words
A conveyor as set forth in claim 2 wherein each of said upper and lower curvilinear guide means includes a pair of laterally spaced apart tracks for each of the upper and lower runs respectively of the pair of endless chains.
Claim 6
Dependent Claim
17 words
A conveyor as set forth in claim 2 wherein the shafts extend substantially normal to each other.
Claim 7
Dependent Claim
30 words
A conveyor as set forth in claim 5 including a plurality of stationary curvilinear pan support bars mounted just below the level of the upper runs of said endless chains.
Claim 8
Dependent Claim
49 words
A conveyor comprising: endless conveyor means for conveying articles between angularly extending conveyors and including first and second oppositely traveling conveyor runs; and first and second curvilinear guide means, having different curvatures, for guiding said first and second runs, respectively, in different curvilinear paths between said angularly extending conveyors.
Claim 9
Dependent Claim
49 words
A conveyor comprising: endless conveyor means for conveying articles between angularly extending conveyors and including first and second oppositely traveling conveyor runs; and first and second curvilinear guide means, having different curvatures, for guiding said first and second runs, respectively, in different curvilinear paths between said angularly extending conveyors.
