Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 102 words
The method of forming a bore having a cushioned bottom in a polyester foam body which comprises, rotating and penetrating into the body, a hollow interior boring tool having a cylindrical exterior surface and a sharp edge extremity formed by an inwardly tapered section extending into the hollow interior, whereby to sever the material from the body to form a cylindrical bore whilst the severed material remains connected to the body in advance of said edge, gathering the material severed inwardly into the interior aforesaid and twisting the material as the bore is formed, the severed material remaining connected to the body.
Claim 2
Independent Claim 102 words
The method of forming a bore having a cushioned bottom in a polyester foam body which comprises, rotating and penetrating into the body, a hollow interior boring tool having a cylindrical exterior surface and a sharp edge extremity formed by an inwardly tapered section extending into the hollow interior, whereby to sever the material from the body to form a cylindrical bore whilst the severed material remains connected to the body in advance of said edge, gathering the material severed inwardly into the interior aforesaid and twisting the material as the bore is formed, the severed material remaining connected to the body.
Claim 3
Independent Claim 116 words
The method of forming a bore having a cushioned bottom in a polyester foam body which comprises, rotating and penetrating into the body, a hollow interior boring tool having a cylindrical exterior surface and a sharp edge extremity formed by an inwardly tapered section extending into the hollow interior, whereby to sever the material from the body to form a cylindrical bore whilst the material remains connected to the body in advance of said edge, gathering the material severed inwardly into the interior aforesaid and twisting the material as the bore is formed and thereafter withdrawing the tool during rotation thereof, the severed material remaining connected to the body at the lower end of said material.
Claim 4
Independent Claim 116 words
The method of forming a bore having a cushioned bottom in a polyester foam body which comprises, rotating and penetrating into the body, a hollow interior boring tool having a cylindrical exterior surface and a sharp edge extremity formed by an inwardly tapered section extending into the hollow interior, whereby to sever the material from the body to form a cylindrical bore whilst the material remains connected to the body in advance of said edge, gathering the material severed inwardly into the interior aforesaid and twisting the material as the bore is formed and thereafter withdrawing the tool during rotation thereof, the severed material remaining connected to the body at the lower end of said material.
Claim 5
Dependent Claim 33 words
The method of claim 1, wherein the gathering and twisting of the severed material causes the same to be compressed in proportion to the diameter and depth of the interior of the tool.
Claim 6
Dependent Claim 32 words
The method of claim 1, wherein the severed material is compressed into the interior of the tool and twisted whilst connection of the severed material is maintained beyond the point of severance.
Claim 7
Dependent Claim 25 words
The method of claim 2, wherein the tool is rotated at a speed in the order of 5000 RPM, during its severing and withdrawal operation.
Claim 8
Dependent Claim 22 words
An article as claimed in claim 1, wherein the cushioning means comprises material severed from the body during formation of the bore.
Claim 9
Dependent Claim 22 words
An article as claimed in claim 6, wherein the material is twisted and compressed and positioned at the bottom of the bore.
Claim 10
Dependent Claim 20 words
An article as claimed in claim 7, wherein the cushioning means is integrally connected to the bottom of the bore.
Claim 11
Dependent Claim 32 words
An article as claimed in claim 7, wherein the cushioning means comprises material severed from the body without creating dust during formation of the bore, and such material is twisted and compressed.
