Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
182 words
A rotary brush comprising: a central hub having a peripheral edge, and wherein a plurality of apertures are formed in predetermined positions adjacent to the peripheral edge of the central hub; and a plurality of knots of wires, each knot of wire individually received through each of the peripherally positioned apertures, and wherein the individual knots of wires include a plurality of individual wires which are twisted about each other, the knots of wires including both standard twist, and full cable twist knots which are positioned in alternating relationship about the peripheral edge of the central hub, and wherein each knot of wire has a proximal end which is positioned adjacent to the central hub and a distal end which defines a knot face, and wherein the knot face of the individual standard twist knots have a given width dimension, and the knot face of the individual full cable twist knots have a width dimension which is less than the width dimension of the standard twist knots, and wherein the individual knot faces form a brush face having a variable width dimension.
Claim 2
Dependent Claim
182 words
A rotary brush comprising: a central hub having a peripheral edge, and wherein a plurality of apertures are formed in predetermined positions adjacent to the peripheral edge of the central hub; and a plurality of knots of wires, each knot of wire individually received through each of the peripherally positioned apertures, and wherein the individual knots of wires include a plurality of individual wires which are twisted about each other, the knots of wires including both standard twist, and full cable twist knots which are positioned in alternating relationship about the peripheral edge of the central hub, and wherein each knot of wire has a proximal end which is positioned adjacent to the central hub and a distal end which defines a knot face, and wherein the knot face of the individual standard twist knots have a given width dimension, and the knot face of the individual full cable twist knots have a width dimension which is less than the width dimension of the standard twist knots, and wherein the individual knot faces form a brush face having a variable width dimension.
Claim 3
Dependent Claim
20 words
A rotary brush as claimed in claim 1, and wherein the individual knots of wire have substantially the same length.
Claim 4
Dependent Claim
128 words
A rotary brush comprising: a central hub having a peripheral edge, and wherein a plurality of apertures are formed in the hub and located in predetermined spaced relation along the peripheral edge; and a plurality of knots of wires, each knot of wire individually received in each of the apertures and wherein the individual knots include a plurality of individual wires which are twisted about each other, and wherein each knot of wire has a distal end defining a knot face which has a predetermined width dimension, and wherein the individual knot faces are oriented in alternating relationship such that each knot face is positioned immediately adjacent to another knot face which has a different width dimension thereby forming a brush face having an undulating width face dimension.
Claim 5
Dependent Claim
128 words
A rotary brush comprising: a central hub having a peripheral edge, and wherein a plurality of apertures are formed in the hub and located in predetermined spaced relation along the peripheral edge; and a plurality of knots of wires, each knot of wire individually received in each of the apertures and wherein the individual knots include a plurality of individual wires which are twisted about each other, and wherein each knot of wire has a distal end defining a knot face which has a predetermined width dimension, and wherein the individual knot faces are oriented in alternating relationship such that each knot face is positioned immediately adjacent to another knot face which has a different width dimension thereby forming a brush face having an undulating width face dimension.
Claim 6
Dependent Claim
34 words
A rotary brush as claimed in claim 3, and wherein the individual knots of wire include standard twist and full cable twist knots in alternating positions about the peripheral edge of the central hub.
Claim 7
Dependent Claim
118 words
A rotary brush comprising: a central hub having a peripheral edge and a plurality of apertures formed in predetermined positions adjacent to the peripheral edge of the central hub; and a plurality of knots of wire, each knot of wire individually received through each of the peripherally positioned apertures and wherein the individual knots include a plurality of individual wires which are twisted about each other, and wherein the knots of wires include both standard twist and full cable twist knots which are positioned in alternating relationship about the peripheral edge of the central hub, and wherein the individual knots of wires are of substantially identical length and form a brush face having an undulating width face dimension.
Claim 8
Dependent Claim
118 words
A rotary brush comprising: a central hub having a peripheral edge and a plurality of apertures formed in predetermined positions adjacent to the peripheral edge of the central hub; and a plurality of knots of wire, each knot of wire individually received through each of the peripherally positioned apertures and wherein the individual knots include a plurality of individual wires which are twisted about each other, and wherein the knots of wires include both standard twist and full cable twist knots which are positioned in alternating relationship about the peripheral edge of the central hub, and wherein the individual knots of wires are of substantially identical length and form a brush face having an undulating width face dimension.
