Abstract

Abstract A conveyor roll adapted for mounting on a shaft comprises a pair of opposed roll halves of a resilient material of semi-cylindrical shape, each having a semi-cylindrical recess. A pair of opposed semi-cylindrical metal insert halves are nested and secured within each roll half and have assembly ends projecting axially outward of the roll halves. Each insert half has an elongated semi-cylindrical recess snugly receiving said shaft. Fasteners interconnect the assembly ends of the inserts securing the inserts together upon the shaft and securing the roll halves together.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 110 words
A conveyor roll adapted for mounting on a shaft comprising a pair of opposed symmetrical roll halves of a non-metallic resilient material of semi-cylindrical shape with parallel end walls, each roll half having a semi-cylindrical recess; a pair of opposed semi-cylindrical metal insert halves nested within and (secured within) bonded to each roll half, respectively and having assembly ends projecting axially outward of said end walls; each insert half having an elongated semi-cylindrical recess snugly receiving said shaft; and fastening means interconnecting said insert half assembly ends face to face, interconnecting said roll halves face to face and for securing the assembled roll halves and insert halves to said shaft.
Claim 2
Dependent Claim 110 words
A conveyor roll adapted for mounting on a shaft comprising a pair of opposed symmetrical roll halves of a non-metallic resilient material of semi-cylindrical shape with parallel end walls, each roll half having a semi-cylindrical recess; a pair of opposed semi-cylindrical metal insert halves nested within and (secured within) bonded to each roll half, respectively and having assembly ends projecting axially outward of said end walls; each insert half having an elongated semi-cylindrical recess snugly receiving said shaft; and fastening means interconnecting said insert half assembly ends face to face, interconnecting said roll halves face to face and for securing the assembled roll halves and insert halves to said shaft.
Claim 3
Dependent Claim 105 words
A conveyor roll adapted for mounting on a shaft comprising a pair of opposed roll halves of a resilient material of semi-cylindrical shape having opposed sides; each roll half having a semi-cylindrical recess; a pair of opposed semi-cylindrical metal insert halves nested within and (secured within) bonded to each roll half respectively; the ends of said insert halves projecting axially outward of said sides; each insert half having an elongated semi-cylindrical recess receiving said shaft; and fastening means interconnecting said projecting insert ends face to face, interconnecting said roll halves face to face and securing the assembled roll halves and insert halves to said shaft.
Claim 4
Dependent Claim 105 words
A conveyor roll adapted for mounting on a shaft comprising a pair of opposed roll halves of a resilient material of semi-cylindrical shape having opposed sides; each roll half having a semi-cylindrical recess; a pair of opposed semi-cylindrical metal insert halves nested within and (secured within) bonded to each roll half respectively; the ends of said insert halves projecting axially outward of said sides; each insert half having an elongated semi-cylindrical recess receiving said shaft; and fastening means interconnecting said projecting insert ends face to face, interconnecting said roll halves face to face and securing the assembled roll halves and insert halves to said shaft.
Claim 5
Dependent Claim 55 words
In the conveyor roll of claim 1, the semi-cylindrical recess in each roll half defining a pair of spaced end faces; the semi-cylindrical recess in each insert half defining a pair of spaced end faces; the respective opposed end faces being in snug surface engagement to define a cylindrical conveyor roll and a cylindrical insert.
Claim 6
Dependent Claim 15 words
In the conveyor roll of claim 1, each roll half being rectangular in cross section.
Claim 7
Dependent Claim 51 words
In the conveyor roll of claim 1, there being a laterally spaced pair of aligned transverse bores in said insert half projecting ends upon opposite sides thereof, one of said aligned bores being threaded; said fastening means being screws projected through said bores respectively and threaded into said threaded bores respectively.
Claim 8
Dependent Claim 45 words
In the conveyor roll of claim 1, said shaft being journalled upon a pair of bearing supports; said conveyor roll when worn or damaged being removable from said shaft and replaceable by a disassembly and subsequent assembly of said fastening means, without disassembling said shaft.
Claim 9
Dependent Claim 32 words
In the conveyor roll of claim 3, the end faces of said roll halves projecting outwardly of said insert half end faces, the assembled roll halves when secured together being in compression.
Claim 10
Dependent Claim 206 words
A conveyor roll adapted for mounting on a shaft comprising a pair of opposed symmetrical roll halves of a non-metallic resilient material of semi-cylindrical shape with parallel end walls, each roll having a semi-cylindrical recess; a pair of opposed semi-cylindrical metal insert halves nested within and bonded to each roll half, respectively and having assembly ends projecting axially outward of said end walls; each insert half having an elongated semi-cylindrical recess snugly receiving said shaft; and fastening means interconnecting said insert half assembly ends face to face, interconnecting said roll halves face to face and for securing the assembled roll halves and insert halves to said shaft; the semi-cylindrical recess in each roll half defining a pair of spaced end faces; the semi-cylindrical recess in each insert half defining a pair of spaced end faces; the respective opposed end faces being in snug surface engagement to define a cylindrical conveyor roll and a cylindrical insert; each roll half being rectangular in cross-section; there being a laterally spaced pair of aligned transverse bores in said insert half projecting ends upon opposite sides thereof, one of said aligned bores being threaded; said fastening means being screws projected through said bores respectively and threaded into said threaded bores respectively.
Claim 11
