Abstract
Abstract The embodiment of the invention disclosed herein is directed to a conveyor roller structure wherein the outer working sleeve portion of the roller is secured to a reusable drive shaft by means of a collar having a non-circular rotational-restricting surface welded to the sleeve at one end of the drive shaft. When the surface of the outer working sleeve of the roller is excessively worn it can be replaced by cutting the collar loose with a cutting torch and sliding the sleeve from the drive shaft. A new sleeve and collar are placed on the drive shaft and secured thereto, thereby allowing a substantial portion of the conveyor roller structure to be used again.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
197 words
A conveyor roller structure comprising: drive shaft means having one end thereof arranged to be journalled and the other end thereof arranged to be driven by drive means, roller sleeve means having end wall portions directed radially inwardly toward said drive shaft means, said end wall portions having apertures formed therein for receiving said drive shaft means, a noncircular rotational-restricting surface means formed on said drive shaft means to be positioned adjacent the axially outwardly located wall surface of one of said end wall portions, said noncircular rotational-restricting surface extending radially outwardly of said drive shaft means, a collar positioned over said drive shaft means to circumscribe said non-circular rotational-restricting surface means, said collar having an internal configuration firmly to engage said non-circular rotational-restricting surface means and a radially inwardly circular flange and means for securing said collar to said one of said wall portions tO capture said noncircular rotationalrestricting surface between said one end of said end wall portion and said radially inwardly circular flange, whereby relative rotational and axial movement between said drive shaft means and said roller sleeve means is prevented, and replacement of said roller sleeve means is accomplished by removing said collar.

A conveyor roller structure comprising: drive shaft means having one end thereof arranged to be journalled and the other end thereof arranged to be driven by drive means, roller sleeve means having end wall portions directed radially inwardly toward said drive shaft means, said end wall portions having apertures formed therein for receiving said drive shaft means, a noncircular rotational-restricting surface means formed on said drive shaft means to be positioned adjacent the axially outwardly located wall surface of one of said end wall portions, said noncircular rotational-restricting surface extending radially outwardly of said drive shaft means, a collar positioned over said drive shaft means to circumscribe said non-circular rotational-restricting surface means, said collar having an internal configuration firmly to engage said non-circular rotational-restricting surface means and a radially inwardly circular flange and means for securing said collar to said one of said wall portions tO capture said noncircular rotationalrestricting surface between said one end of said end wall portion and said radially inwardly circular flange, whereby relative rotational and axial movement between said drive shaft means and said roller sleeve means is prevented, and replacement of said roller sleeve means is accomplished by removing said collar.
Claim 3
Dependent Claim
38 words
The conveyor roller structure according to claim 1 wherein said non-circular rotational-restricting surface means is formed of a pair of diametrically opposed flat wall portions formed at the periphery of a circular section of said drive shaft means.
Claim 4
Dependent Claim
55 words
The conveyor roller structure according to claim 1 wherein at least one of said end wall portions of said roller sleeve means has a plurality of heat venting openings formed about the central aperture thereof for releasing heat buildup which occurs between said drive shaft means and the interior surface of said roller sleeve means.
Claim 5
Dependent Claim
54 words
The conveyor roller structure according to claim 1 wherein the apertures formed in said end wall portions to receive said drive shaft means are sized to be frictionally engaged with said drive shaft means to allow axial expansion of said roller sleeve means thereupon as the result of elevated temperatures which occur during operation.
Claim 6
Dependent Claim
44 words
The conveyor roller structure according to claim 1 wherein said means for securing said collar to said one of said wall portions comprises weld metal deposited about the periphery of said collar for weldably binding said collar to said one of said wall portions.
