Abstract
Abstract A cleaner for a conveyor belt. The cleaner is mounted below and across the returning run of the conveyor belt so as to scrape off leavings adhered to the belt. The cleaner comprises a beam mounted transversely to the returning run of the conveyor belt and a plurality of scraper means fixed to the beam. The scraper means includes a scraping member having a tip of super-hard metal at the upper end thereof, a plate for mounting the scraping member on a thick resilient member fixed to the beam, the tip of the scraping member being adapted to follow the vibrations of the belt by means of the resilient member. A transverse groove can be provided in the upper and/or lower face of the resilient member. The resilient member may be in the shape of a substantially triangular pillar.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
118 words
A cleaner for a conveyor belt comprising a beam mounted below a return run of a conveyor belt transversely to the direction of movement thereof, a plurality of scraper means mounted along said beam, each consisting of a resilient member consisting of a solid block of resilient material having two spaced plate attaching surfaces thereon, a scraper member plate having the surface at the lower end thereof fixed to one of the plate attaching surfaces on said resilient member and a scraping member on the upper end of said scraper member plate, and a mounting plate having the surface fixed to the other plate attaching surface of said resilient member, said mounting plate being attached to said beam.
Claim 2
Dependent Claim
118 words
A cleaner for a conveyor belt comprising a beam mounted below a return run of a conveyor belt transversely to the direction of movement thereof, a plurality of scraper means mounted along said beam, each consisting of a resilient member consisting of a solid block of resilient material having two spaced plate attaching surfaces thereon, a scraper member plate having the surface at the lower end thereof fixed to one of the plate attaching surfaces on said resilient member and a scraping member on the upper end of said scraper member plate, and a mounting plate having the surface fixed to the other plate attaching surface of said resilient member, said mounting plate being attached to said beam.
Claim 3
Dependent Claim
52 words
A cleaner as claimed in claim 1 in which said solid block of resilient member is a rectangular cross-section block with one of said plate attaching surfaces being on one vertically oriented face of said block and the other plate attaching surface being on the opposite vertically oriented face of said block.
Claim 4
Dependent Claim
48 words
A cleaner as claimed in claim 2 in which said beam has a horizontal surface thereon and a vertical flange projecting upwardly from said horizontal surface to which said mounting plate is attached, the lower surface of said block being spaced above the horizontal surface of said beam.
Claim 5
Dependent Claim
34 words
A cleaner as claimed in claim 2 in which said block has a transverse groove in at least one of the horizontal surfaces of said block, said groove having a concavely curved cross section.
Claim 6
Dependent Claim
20 words
A cleaner as claimed in claim 4 in which said groove is in only the upper surface of the block.
Claim 7
Dependent Claim
20 words
A cleaner as claimed in claim 4 in which said groove is in only the lower surface of the block.
Claim 8
Dependent Claim
18 words
A cleaner as claimed in claim 4 in which both surfaces of said block have a groove therein.
Claim 9
Dependent Claim
78 words
A cleaner as claimed in claim 1 in which said block is a right triangular prism in which the bottom oblong surface thereof constitutes one of said plate attaching faces and the upper portion of the vertical oblong surface constitutes the other plate attaching face, the bottom oblong surface being attached to said mounting plate, and the remaining oblong surface being on a slant and being opposed to the lower surface of the return run of the belt.
Claim 10
Dependent Claim
44 words
A cleaner as claimed in claim 1 further comprising angle adjusting means on said beam to which said mounting plates are attached, said angle adjusting means being movable to adjust the angle of said scraper means relative to the return run of the belt.
