Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
72 words
An elongated rotor for flexible screw-type conveyors and the like comprising an elongated helical strip having a round bead extending along the central axis thereof and constituting a continuous core formed integrally therewith, and a plurality of stranded cables wound about said bead with the same pitch as said helical strip, said cables lying in engagement with one another and said bead and retaining said helical strip securely in its helical configuration.
Claim 2
Dependent Claim
72 words
An elongated rotor for flexible screw-type conveyors and the like comprising an elongated helical strip having a round bead extending along the central axis thereof and constituting a continuous core formed integrally therewith, and a plurality of stranded cables wound about said bead with the same pitch as said helical strip, said cables lying in engagement with one another and said bead and retaining said helical strip securely in its helical configuration.
Claim 3
Dependent Claim
25 words
The rotor of claim 1 wherein said cables and said strip are of synthetic plastic material having a specific gravity less than that of water.
Claim 4
Dependent Claim
76 words
An elongated rotor for flexible screw-type conveyors comprising a central tension carrying rope, a second rope extending about said tension rope in helical configuration, means for bonding said second rope to said tension rope, said second rope having a hollow tubular center member of flexible fluid-tight material, a terminal fitting, a member rotatable with respect thereto, and means for affording communication for fluid from said relatively rotatable member through said fitting to said center tubular member.
Claim 5
Dependent Claim
76 words
An elongated rotor for flexible screw-type conveyors comprising a central tension carrying rope, a second rope extending about said tension rope in helical configuration, means for bonding said second rope to said tension rope, said second rope having a hollow tubular center member of flexible fluid-tight material, a terminal fitting, a member rotatable with respect thereto, and means for affording communication for fluid from said relatively rotatable member through said fitting to said center tubular member.
Claim 6
Dependent Claim
54 words
An elongated rotor for flexible screw-type conveyors comprising a central tension carrying multiple strand rope, a helical member bonded to said rope for rotation therewith, and means on said helical member spaced from and facing said rope and proViding an axially facing open channel extending from said member about the periphery of said rope.
Claim 7
Dependent Claim
54 words
An elongated rotor for flexible screw-type conveyors comprising a central tension carrying multiple strand rope, a helical member bonded to said rope for rotation therewith, and means on said helical member spaced from and facing said rope and proViding an axially facing open channel extending from said member about the periphery of said rope.
Claim 8
Dependent Claim
43 words
The rotor of claim 3 including at least two helical cables wound in opposite directions about said central rope for gripping said central tension carrying rope tightly when under tension and for facilitating the connection of a driving member to said central rope.
Claim 9
Dependent Claim
38 words
The rotor of claim 5 including a rigid fitting mounted about said central rope at the end thereof and having at least one passage for receiving said cables and means for connecting said cables securely to said fitting.
Claim 10
Dependent Claim
20 words
The rotor of claim 2 including tubes of synthetic plastic material each closely surrounding a respective one of said cables.
