Method for making a roller assembly for grain shellers
First Claim
1. A method for making a roller assembly, the method comprising providing a round, tubular, rigid metal first sleeve, forming first and second apertures extending radially through said first sleeve, bonding a second sleeve to the entire exterior surface of said first sleeve with material of said second sleeve entering and filling said first apertures during said bonding, shielding said second apertures such that said material does not enter said second apertures during said bonding, and removing said shielding after said bonding, to provide a laminate sleeve assembly with parts of said second sleeve extending through said first sleeve to the interior surface of said first sleeve, and providing a mounting hub assembly comprising a circular wall having ribs extending from said wall and substantially normal thereto, sliding said sleeve assembly onto said ribs, providing locking plates adapted for connection to said wall and having recess means therein alignable with said sleeve assembly second apertures, locating pins in said locking plate recess means, disposing said locking plates such that said pins enter said sleeve assembly second apertures, and fixing said locking plates to said wall, whereby to connect said sleeve assembly to said mounting hub to form said roller assembly.

Abstract
A method for making a roller sleeve assembly comprising providing a metal sleeve, forming apertures extending radially through the sleeve, bonding a flexible sleeve to the exterior of the metal sleeve and permitting the flexible sleeve material to fill certain of the apertures. The invention further contemplates a method for making a roller assembly comprising sliding the above-described sleeve assembly onto a hub comprising a circular wall with ribs extending normally therefrom, and providing locking plates and cooperative pins for locking the sleeve assembly onto the hub, with the pins disposed partly in the locking plates and partly in other of the sleeve assembly apertures.

9. A method for making a roller assembly, the method comprising providing a rigid metal first sleeve, forming first and second apertures extending radially through said first sleeve, bonding a second sleeve to the substantially entire exterior surface of said first sleeve with material of said second sleeve entering and filling said first aperture during said bonding, providing a mounting hub assembly comprising a wall having ribs extending therefrom, said ribs being disposed in circular fashion and adapted to slidingly receive said first sleeve, and providing means on said hub assembly for locking said first sleeve onto said hub assembly, said locking means including pin means adapted to extend into said second aperture of said first sleeve.
