Abstract
Abstract A conveyor in which a three-dimensionally closed chain carrying a plurality of uniformly spaced horizontal spindles has mounted thereon rods with platforms for supporting the piles or batches. In places where the rods are mounted on respective spindles, each spindle has fixed thereto a half-coupling held in permanent engagement with another half-coupling freely rotatable about the horizontal spindle and fixed to the rod. The provision of the half-couplings prevents a rocking motion of the platforms, as the chain is being forwarded, because any deviation of a platform from the horizontal position results in the two respective halfcouplings being displaced relative to each other.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
142 words
A conveyor for forwarding piles of printed signatures such as newspapers, including a closed three-dimensional chain adapted to be advanced; means for effecting advancing of said chain; a plurality of substantially horizontal spindles uniformly spaced along said chain and carried thereby; a respective plurality of rods mounted on said spindles in a cantilever fashion, platforms for supporting said piles of printed signatures mounted on said rods; a first half-coupling fixed to each said spindle at the area of mounting thereon of the respective one of said rods; a second half-coupling freely rotatable about each said spindle and fixed to the respective one of said rods, said half-couplings being maintained in permanent resilient engagement to retain said respective platforms together with said piles carried thereby against rocking motion, as said chain is being advanced; and means urging said half-couplings into permanent resilient engagement.
Claim 2
Dependent Claim
142 words
A conveyor for forwarding piles of printed signatures such as newspapers, including a closed three-dimensional chain adapted to be advanced; means for effecting advancing of said chain; a plurality of substantially horizontal spindles uniformly spaced along said chain and carried thereby; a respective plurality of rods mounted on said spindles in a cantilever fashion, platforms for supporting said piles of printed signatures mounted on said rods; a first half-coupling fixed to each said spindle at the area of mounting thereon of the respective one of said rods; a second half-coupling freely rotatable about each said spindle and fixed to the respective one of said rods, said half-couplings being maintained in permanent resilient engagement to retain said respective platforms together with said piles carried thereby against rocking motion, as said chain is being advanced; and means urging said half-couplings into permanent resilient engagement.
Claim 3
Dependent Claim
42 words
The conveyor as claimed in claim 1, wherein said half-coupling fixed to said spindle is integral with said spindle, and said means urging said half-couplings into permanent resilient engagement including a spring having one end thereof secured to said substantially horizontal spindle.
Claim 4
Dependent Claim
26 words
The conveyor as claimed in claim 1, wherein said half-couplings have serrated engagement surfaces to increase friction between said respective engagement surfaces of said two half-couplings.
Claim 5
Dependent Claim
75 words
The conveyor as claimed in claim 1, including a follower mounted on each said substantially horizontall spindle, said chain having portions of the path thereof, where the plane of said path varies, and a stationary cam mounted adjacent to each said portion to be engaged by said follower to effect correction of the position occupied in space by the respective ones of said platforms, as said chain travels from one said portion to another one.
Claim 6
Dependent Claim
63 words
The conveyor as claimed in claim 1, including a follower mounted on each said platform, said chain having portions of the path thereof, corresponding the areas, respectively, of loading and unloading of said platforms, and a stationary cam mounted adjacent to each said portion to be engaged by said follower to index the respective one of said platforms into a strictly horizontal position.
