Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
116 words
An article of commerce for abrading irregularly shaped objects comprising: (a) a sheet of non-resilient flexible woven material cut on the bias so as to be formable to conform to the configuration of an irregularly shaped object having multiple planes and having the further characteristic of retaining said irregular configuration in said multiple planes until the sheet is formed into another configuration; (b) a layer of flexible adhesive also conformable to said multiple planes and adherent on said sheet material; and (c) abrasive material bonded to said sheet by said adhesive layer, said sheet, adhesive and abrasive being shapable to conform simultaneous to the multiple planes of the irregular surface of an object to be abraded.
Claim 2
Dependent Claim
116 words
An article of commerce for abrading irregularly shaped objects comprising: (a) a sheet of non-resilient flexible woven material cut on the bias so as to be formable to conform to the configuration of an irregularly shaped object having multiple planes and having the further characteristic of retaining said irregular configuration in said multiple planes until the sheet is formed into another configuration; (b) a layer of flexible adhesive also conformable to said multiple planes and adherent on said sheet material; and (c) abrasive material bonded to said sheet by said adhesive layer, said sheet, adhesive and abrasive being shapable to conform simultaneous to the multiple planes of the irregular surface of an object to be abraded.
Claim 3
Dependent Claim
93 words
An article of commerce for abrading irregularly shaped objects, comprising: (a) a mass of moldable material having the characteristic of plasticity so as to enable said mass to be molded a desired configuration such that the surfaces of said mass conform to an irregularly shaped surface to abraded, said moldable mass having the further characteristic of retaining said desired configuration until said mass is again molded into another configuration; and (b) a layer of abrasive material adherent to said mass and conformable with said mass to the irregularly shaped surface to be abraded.
Claim 4
Dependent Claim
93 words
An article of commerce for abrading irregularly shaped objects, comprising: (a) a mass of moldable material having the characteristic of plasticity so as to enable said mass to be molded a desired configuration such that the surfaces of said mass conform to an irregularly shaped surface to abraded, said moldable mass having the further characteristic of retaining said desired configuration until said mass is again molded into another configuration; and (b) a layer of abrasive material adherent to said mass and conformable with said mass to the irregularly shaped surface to be abraded.
Claim 5
Dependent Claim
26 words
The combination according to claim 2, in which a membrane is adhered to said mass of moldable material, and said abrasive is adhered to said membrane.
Claim 6
Dependent Claim
71 words
The combination according to claim 2, wherein said mass having the characteristic of plasticity is enclosed within a membrane which is impervious to fluids and which is conformable with said mass to the irregularly shaped surface to be abraded, wherein a sheet of non-resilient flexible material formable about said mass is disposed over said membrane, and wherein a layer of abrasive material is adhered to said sheet of non-resilient flexible material.
Claim 7
Dependent Claim
108 words
An article of commerce for abrading irregularly shaped objects, comprising: (a) a body of material having the characteristic of plasticity to enable conformation of surfaces of the body of material to an irregularly shaped surface to be abraded, said body of material having the further characteristic of retaining the surface configuration thereof; (b) a sheet of non-resilient flexible material draped about said body and conformable thereto; (c) a layer of flexible adhesive adherent on said sheet material; and (d) abrasive material bonded to said sheet by said adhesive layer whereby said sheet, adhesive and abrasive may be shaped to conform to the irregularly shaped surface to be abraded.
Claim 8
Dependent Claim
108 words
An article of commerce for abrading irregularly shaped objects, comprising: (a) a body of material having the characteristic of plasticity to enable conformation of surfaces of the body of material to an irregularly shaped surface to be abraded, said body of material having the further characteristic of retaining the surface configuration thereof; (b) a sheet of non-resilient flexible material draped about said body and conformable thereto; (c) a layer of flexible adhesive adherent on said sheet material; and (d) abrasive material bonded to said sheet by said adhesive layer whereby said sheet, adhesive and abrasive may be shaped to conform to the irregularly shaped surface to be abraded.
Claim 9
Dependent Claim
128 words
An article of commerce for abrading irregularly shaped objects comprising: (a) a mass of moldable material having the characteristic of plasticity so as to enable said mass to be molded into a desired configuration such that the surfaces of said mass conform to an irregularly shaped surface to be abraded, said moldable mass having the further characteristic of retaining said desired configuration until said mass is again molded into another configuration; (b) a fluid impervious membrane having said mass of moldable material enclosed therein, said membrane being conformable with said mass to the irregularly shaped surface to be abraded; (c) sheet of non-resilient flexible material formable about said mass disposed over said membrane; and (d) a layer of abrasive material adhered to said sheet of non-resilient flexible material.
Claim 10
Dependent Claim
128 words
An article of commerce for abrading irregularly shaped objects comprising: (a) a mass of moldable material having the characteristic of plasticity so as to enable said mass to be molded into a desired configuration such that the surfaces of said mass conform to an irregularly shaped surface to be abraded, said moldable mass having the further characteristic of retaining said desired configuration until said mass is again molded into another configuration; (b) a fluid impervious membrane having said mass of moldable material enclosed therein, said membrane being conformable with said mass to the irregularly shaped surface to be abraded; (c) sheet of non-resilient flexible material formable about said mass disposed over said membrane; and (d) a layer of abrasive material adhered to said sheet of non-resilient flexible material.
Claim 11
Dependent Claim
