Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
156 words
In a tufting machine needle having a shank with an elongated blade depending from the shank and terminating in a tip, the improvement wherein said blade has a pair of eyes, an upper one of said eyes being located adjacent said shank and the other lower one of said eyes being located adjacent said tip, both of said eyes extending through said blade from one side thereof to the other, said one side of said blade having an elongated yarn guide groove extending laterally of said eyes from substantially said tip to said shank, said other side of said blade having a looper recess disposed between said eyes, said eyes being spaced apart vertically a substantial distance, so that when the needle is mounted in a tufting machine and backing fabric is presented to the needle, the upper eye adjacent the shank does not penetrate the backing fabric when the needle is in its lowermost position.
Claim 2
Dependent Claim

In a tufting machine needle having a shank with an elongated blade depending from the shank and terminating in a tip, the improvement wherein said blade has a pair of eyes, an upper one of said eyes being located adjacent said shank and the other lower one of said eyes being located adjacent said tip, both of said eyes extending through said blade from one side thereof to the other, said one side of said blade having an elongated yarn guide groove extending laterally of said eyes from substantially said tip to said shank, said other side of said blade having a looper recess disposed between said eyes, said eyes being spaced apart vertically a substantial distance, so that when the needle is mounted in a tufting machine and backing fabric is presented to the needle, the upper eye adjacent the shank does not penetrate the backing fabric when the needle is in its lowermost position.
Claim 3
Dependent Claim
36 words
The tufting needle according to claim 1 wherein said looper recess is located on said blade relative to said upper eye as to have passed through said backing when the needle is in said lowermost position.
Claim 4
Dependent Claim
59 words
The tufting needle according to claim 1 wherein said recess has a beveled surface on said blade inclining transversely across the center of the blade to merge with said other side of the blade and extending both transversely and longitudinally adjacent its upper and lower end portions to effect a gradual merger with said other side of the blade.
Claim 5
Dependent Claim
73 words
The tufting needle according to claim 1 wherein the lower end of said upper eye and the upper end of said lower eye have cuttings arranged relative to one another and said yarn guide groove in said one side of said blade to dispose a yarn in said groove laterally along one side of the groove when the yarn is threaded through both eyes so as to lay in said yarn guide groove.
Claim 6
Dependent Claim
61 words
The tufting needle according to claim 1 wherein said blade is relatively flat and said upper and lower eyes are vertically elongated and have widthwise dimensions corresponding to about half the width of the blade for accommodating a pair of pile yarns side by side in said yarn guide groove when both pile yarns are threaded through both of said eyes.
