Abstract
Abstract The invention is concerned with cleaning of material from conveyor belts and consists of at least one pair of blades each extending partway across a belt to be cleaned. The contiguous ends of the blades are made to overlap each other in the vicinity of the center line of the belt. The blades are mounted so that they can pivot about axes located parallel to and within the width of the belts while carried in mountings which can pivot about axes transverse to the belt. There may be a plurality of pairs of blades and the mountings will be supported in hangers which are also pivoted about axes extending across the belt.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
134 words
A conveyor belt cleaner, comprising: a plurality of blades engagable with a conveyor belt for scraping same clean, the length of each blade being substantially less than the width of the major portion of said conveyor belt; and means separately mounting said blades for pivotal movement about their separate respective axes of rotation substantially parallel to the longitudinal axiS of said belt; said blades being mounted transversely of said belt such that adjacent blades are offset with respect to each other and such that opposite end portions of said adjacent blades overlap each other in spaced relation near the center of said belt and further such that the combined width of said blades extends across the major portion of the width of said belt from the center of the belt toward the edges thereof.
Claim 2
Dependent Claim
134 words
A conveyor belt cleaner, comprising: a plurality of blades engagable with a conveyor belt for scraping same clean, the length of each blade being substantially less than the width of the major portion of said conveyor belt; and means separately mounting said blades for pivotal movement about their separate respective axes of rotation substantially parallel to the longitudinal axiS of said belt; said blades being mounted transversely of said belt such that adjacent blades are offset with respect to each other and such that opposite end portions of said adjacent blades overlap each other in spaced relation near the center of said belt and further such that the combined width of said blades extends across the major portion of the width of said belt from the center of the belt toward the edges thereof.
Claim 3
Dependent Claim
24 words
A conveyor belt cleaner according to claim 1, wherein said blades are disposed substantially at right angles to the longitudinal axis of said belt.
Claim 4
Dependent Claim
32 words
A conveyor belt cleaner according to claim 1, comprising further mounting means mounting said blades for pivotal movement about an axis of rotation substantially perpendicular to the longitudinal axis of said belt.
Claim 5
Dependent Claim
41 words
A conveyor belt cleaner according to claim 3, wherein said separate mounting means comprises first and second members fixed to said further mounting means, said blades being mounted on said first and second members, respectively, for rotation relative to said members.
Claim 6
Dependent Claim
93 words
A conveyor belt cleaner according to claim 3, comprising a plurality of pairs of said overlapping blades, said pairs of blades being located along the direction of travel of said belt and wherein at least one pair of blades is mounted on one side of said further mounting means relative to the longitudinal direction of movement of said belt and at least one further pair of blades is mounted on the opposite side of said further mounting means from said pair of blades relative to the longitudinal direction of movement of said belt.
Claim 7
Dependent Claim
44 words
A conveyor belt cleaner according to claim 5, wherein at least two pairs of blades are mounted on said further mounting means on said one side thereof and one pair of blades is mounted on said further mounting means on said opposite side thereof.
Claim 8
Dependent Claim
45 words
A conveyor belt cleaner according to claim 1, wherein said plurality of blades comprises a plurality of pairs of said overlapping blades mounted on said mounting means, said pairs of blades being located one behind the other in the direction of travel of said belt.
