Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
130 words
A method of assembling a spaghetti seal in a groove in a first part to be sealed to a confronting second part, said groove including a bottom and an opening remote from said bottom, comprising the steps of: providing a spaghetti seal comprising an elastomeric sealing member for sealing against said confronting second part, and a stiffening member affixed thereto to rigidify said sealing member for installation, said stiffening member having a base, and installing said spaghetti seal by inserting said stiffening member into said groove so that said stiffening member enters said groove opening before said elastomeric sealing member, with said sealing member projecting outwardly of said groove opening to confront said confronting second part and said base of said stiffening member resting along the bottom of said groove.
Claim 2
Independent Claim
130 words
A method of assembling a spaghetti seal in a groove in a first part to be sealed to a confronting second part, said groove including a bottom and an opening remote from said bottom, comprising the steps of: providing a spaghetti seal comprising an elastomeric sealing member for sealing against said confronting second part, and a stiffening member affixed thereto to rigidify said sealing member for installation, said stiffening member having a base, and installing said spaghetti seal by inserting said stiffening member into said groove so that said stiffening member enters said groove opening before said elastomeric sealing member, with said sealing member projecting outwardly of said groove opening to confront said confronting second part and said base of said stiffening member resting along the bottom of said groove.
Claim 3
Dependent Claim
46 words
The method of claim 1 wherein said groove further includes opposing sides and said elastomeric sealing member further includes a pair of opposing retaining beads, and wherein said spaghetti seal is installed so that said retaining beads frictionally bear against said opposing sides of said groove.
Claim 4
Dependent Claim
40 words
The method of claim 1 wherein said elastomeric sealing member further includes a pair of sealing ribs projecting away from said stiffening member, and wherein said spaghetti seal is installed so that said sealing ribs project beyond said groove opening.
Claim 5
Independent Claim
176 words
A method of assembling a spaghetti seal in a narrow groove in a first automotive engine part to be sealed to a confronting second automotive engine part, said groove including a bottom, opposing side walls, and an opening opposite said bottom, comprising the steps of: providing a spaghetti seal comprising a limp elastomeric sealing member for sealing against said confronting second part, and a stiffening member affixed thereto to rigidify said limp sealing member, said sealing member having a head portion surrounded by said stiffening member and shoulders abutting against said stiffening member, said sealing member further having sides and a pair of opposing retaining beads projecting outwardly from said sides and beyond said stiffening member, positioning said spaghetti seal to overlie said groove, and installing said spaghetti seal by forcing said stiffening member into said groove so that said stiffening member lies entirely within said groove along said groove bottom and said retaining beads resiliently bear against the groove walls, said sealing member projecting outwardly from said groove opening to confront said confronting second part.
Claim 6
Independent Claim
176 words
A method of assembling a spaghetti seal in a narrow groove in a first automotive engine part to be sealed to a confronting second automotive engine part, said groove including a bottom, opposing side walls, and an opening opposite said bottom, comprising the steps of: providing a spaghetti seal comprising a limp elastomeric sealing member for sealing against said confronting second part, and a stiffening member affixed thereto to rigidify said limp sealing member, said sealing member having a head portion surrounded by said stiffening member and shoulders abutting against said stiffening member, said sealing member further having sides and a pair of opposing retaining beads projecting outwardly from said sides and beyond said stiffening member, positioning said spaghetti seal to overlie said groove, and installing said spaghetti seal by forcing said stiffening member into said groove so that said stiffening member lies entirely within said groove along said groove bottom and said retaining beads resiliently bear against the groove walls, said sealing member projecting outwardly from said groove opening to confront said confronting second part.
Claim 7
Dependent Claim
58 words
The method of claim 4 wherein said sealing member further includes a pair of sealing ribs projecting away from said stiffening member, wherein said rigidifying member is plastic, and wherein said installing step further includes the step of forcing said stiffening member into said groove to a depth such that said sealing ribs remain outside of said groove.
