## Abstract

A lower work tool having a one-piece open style design with a plurality of openings and an upper work tool having a housing and cover plate each forming a plurality of openings.

## Claims

### Claim 1

A tool mechanism for use in the deep rolling of crankshafts or like products, comprising:
a) a housing having a side forming an annular opening,
b) a cage formed at one end of said housing,
c) work rollers operatively mounted in said cage and operatively inclined outward to physically engage a fillet of said crankshaft, and
d) at least one annular cover plate secured to said housing at said annular opening, said annular cover plate having a plurality of openings.

### Claim 2 (depends on 1)

The tool mechanism of claim 1 wherein said housing forms a second plurality of openings at a side opposite said annular opening.

### Claim 3 (depends on 2)

The tool mechanism of claim 2 wherein said first and second plurality of openings form disjoined concentric circles radiating outwardly from the center of said housing and cover plate, respectively.

### Claim 4 (depends on 1)

The tool mechanism of claim 1 wherein said housing and cover plate are manufactured from 4140 preheat, armorclad coat, steel.

### Claim 5

A tool mechanism for use in the deep rolling of crankshafts or like products, comprising:
a) two receiving rollers,
b) a pair of spaced hubs rotatably supporting said receiving rollers, and
c) a main body essentially forming an L shape member, said L shape member supporting two laterally spaced sides, each side is symmetrically aligned relative to the other and each side forms a pair of spaced ridges, with said ridges supporting said hubs.

### Claim 6 (depends on 5)

A tool mechanism of claim 5 wherein said main body and ridges form a plurality of openings.

### Claim 7 (depends on 5)

A tool mechanism of claim 5 wherein said main body is manufactured from 4140 preheat, armorclad coat, steel.

### Claim 8

A tool mechanism for use in the deep rolling of crankshafts or like products, comprising:
a) a housing having a side forming an annular opening,
b) a cage formed at one end of said housing,
c) work rollers operatively mounted in said cage and operatively inclined outward to physically engage a fillet of said crankshaft,
d) at least one annular cover plate secured to said housing at said annular opening, said annular cover plate having a plurality of openings,
e) two receiving rollers,
f) a pair of hubs rotatably supporting said receiving rollers, and
g) a main body essentially forming an L shape member, said L shape member supporting two laterally spaced sides, each side is symmetrically aligned relative to the other and each side forms a pair of spaced ridges, with said ridges supporting said hubs, said receiving rollers engage said fillet of said crankshaft opposite said engagement by said work rollers during the deep rolling process.

### Claim 9 (depends on 8)

The tool mechanism of claim 8 wherein said housing forms a second plurality of openings at a side opposite said annular opening.

### Claim 10 (depends on 9)

The tool mechanism of claim 9 wherein said first and second plurality of openings form disjoined concentric circles radiating outwardly from the center of said housing and cover plate, respectively.

### Claim 11 (depends on 8)

A tool mechanism of claim 8 wherein said main body and ridges form a plurality of openings.

### Claim 12 (depends on 8)

A tool mechanism of claim 8 wherein said main body and housing is manufactured from 4140 preheat, armorclad coat, steel.
