Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
180 words
A modular abrasive wheel assembly adapted for mounting on a driven arbor, said arbor having shoulder means spaced from the end thereof and having a nut threaded on said end, said assembly comprising a pair of opposed spaced cylindrical aluminum hubs, a frusto-conical surface on the outer periphery of each hub, said frusto-conical surfaces presenting a V-shaped profile in assembly, a separate unitary steel band around said hub, a coating of crushed tungsten carbide on the outer periphery of said band, a pair of spaced beveled surfaces on the inside diameter of said band, said beveled surfaces matching and engaging respective frusto-conical surfaces of said hubs near the sides of said assembly, an inner cylindrical surface connecting said beveled surfaces and being entirely spaced from said hubs, aligned central apertures through the sides of said hub, a bushing received in said apertures and mounted on said arbor, a plurality of threaded apertures through one of said hubs, a tap screw in each of said apertures, and a washer between said nut and said one hub, said washer covering said apertures.
Claim 2
Dependent Claim
180 words
A modular abrasive wheel assembly adapted for mounting on a driven arbor, said arbor having shoulder means spaced from the end thereof and having a nut threaded on said end, said assembly comprising a pair of opposed spaced cylindrical aluminum hubs, a frusto-conical surface on the outer periphery of each hub, said frusto-conical surfaces presenting a V-shaped profile in assembly, a separate unitary steel band around said hub, a coating of crushed tungsten carbide on the outer periphery of said band, a pair of spaced beveled surfaces on the inside diameter of said band, said beveled surfaces matching and engaging respective frusto-conical surfaces of said hubs near the sides of said assembly, an inner cylindrical surface connecting said beveled surfaces and being entirely spaced from said hubs, aligned central apertures through the sides of said hub, a bushing received in said apertures and mounted on said arbor, a plurality of threaded apertures through one of said hubs, a tap screw in each of said apertures, and a washer between said nut and said one hub, said washer covering said apertures.
Claim 3
Dependent Claim
138 words
A modular abrasive wheel assembly comprising a pair of opposed hubs, said hubs being spaced from one another to provide an air space therebetween, each hub having a frusto-conical outer periphery such that the hubs together present a V-shaped profile in the assembly, a unitary band around said hub, said band having a pair of spaced beveled inner surfaces engaging respective frusto-conical surfaces of said hubs at the sides of said assembly, a cylindrical inner surface connecting said beveled surfaces and spaced from said hubs, a coating of abrasive material on the outside surface of said band, and means within one of said hubs for forcing said hubs apart including a plurality of threaded apertures through the side of one of said hubs, and screws in said apertures, said screws being engageable with the other of said hubs.
Claim 4
Dependent Claim
138 words
A modular abrasive wheel assembly comprising a pair of opposed hubs, said hubs being spaced from one another to provide an air space therebetween, each hub having a frusto-conical outer periphery such that the hubs together present a V-shaped profile in the assembly, a unitary band around said hub, said band having a pair of spaced beveled inner surfaces engaging respective frusto-conical surfaces of said hubs at the sides of said assembly, a cylindrical inner surface connecting said beveled surfaces and spaced from said hubs, a coating of abrasive material on the outside surface of said band, and means within one of said hubs for forcing said hubs apart including a plurality of threaded apertures through the side of one of said hubs, and screws in said apertures, said screws being engageable with the other of said hubs.
Claim 5
Dependent Claim
134 words
A modular abrasive wheel assembly comprising a pair of opposed hubs, said hubs being spaced from one another to proVide an air space therebetween, each hub having a frusto-conical outer periphery such that the hubs together present a V-shaped profile in the assembly, a unitary band around said hub, said band having a pair of spaced beveled inner surfaces engaging respective frusto-conical surfaces of said hubs at the sides of said assembly, a cylindrical inner surface connecting said beveled surfaces and spaced from said hubs, a coating of abrasive material on the outside surface of said band, said hubs having aligned central axial apertures therein, a bushing removably mounted in said apertures, said bushing being shorter than the width of said assembly, and means within one of said hubs for forcing said hubs apart.
Claim 6
Dependent Claim
134 words
A modular abrasive wheel assembly comprising a pair of opposed hubs, said hubs being spaced from one another to proVide an air space therebetween, each hub having a frusto-conical outer periphery such that the hubs together present a V-shaped profile in the assembly, a unitary band around said hub, said band having a pair of spaced beveled inner surfaces engaging respective frusto-conical surfaces of said hubs at the sides of said assembly, a cylindrical inner surface connecting said beveled surfaces and spaced from said hubs, a coating of abrasive material on the outside surface of said band, said hubs having aligned central axial apertures therein, a bushing removably mounted in said apertures, said bushing being shorter than the width of said assembly, and means within one of said hubs for forcing said hubs apart.
Claim 7
Dependent Claim
27 words
The modular abrasive wheel assembly of claim 3 wherein said band is no thicker than about three-sixteenths of an inch and said hubs are composed of aluminum.
