Abstract
Abstract A tufting needle construction in which the axis of the eye and point portion of the needle is parallel but offset relative to the axis of the needle and the blade of the needle just above the needle eye is parallel but offset relative to the eye and point portion to form the clearance above the eye portion of the needle. The axis of the eye and point portion passes into the clearance above the eye. The construction is such that the cross section of the needle at the eye is less than that of known needles of similar gauge and the clearance above the eye may be equal to or greater than that of such known needles.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
106 words
A needle for tufting or the like including a shank having a longitudinal axis, a blade extending from said shank, an eye and point portion including a transverse eye connected to said blade and terminating in a tip, said blade having a longitudinal groove on one side terminating at the eye, said eye and point portion having an axis parallel to and offset relative to said longitudinal axis away from said groove side, and means defining a shoulder at the junction of the eye and point portion with the blade on the side toward which the axis is offset to define a clearance above the eye.
Claim 2
Dependent Claim
106 words
A needle for tufting or the like including a shank having a longitudinal axis, a blade extending from said shank, an eye and point portion including a transverse eye connected to said blade and terminating in a tip, said blade having a longitudinal groove on one side terminating at the eye, said eye and point portion having an axis parallel to and offset relative to said longitudinal axis away from said groove side, and means defining a shoulder at the junction of the eye and point portion with the blade on the side toward which the axis is offset to define a clearance above the eye.
Claim 3
Dependent Claim
23 words
A needle as recited in claim 1 wherein the axis of the eye and point portion passes through the clearance above the eye.
Claim 4
Dependent Claim
34 words
A needle as recited in claim 1 where said blade on the groove side adjacent said junction is deflected toward said longitudinal axis to define a ramp merging with the eye and point portion.
Claim 5
Dependent Claim
27 words
A needle as recited in claim 3 wherein the sides of said blade at the clearance above the eye is narrower than the remainder of the blade.
Claim 6
Dependent Claim
32 words
A needle as recited in claim 3 wherein the axis of the blade in the clearance above the eye is offset from said longitudinal axis toward the groove side of said blade.
Claim 7
Dependent Claim
19 words
A needle as recited in claim 5 wherein said axis of the blade is parallel to the longitudinal axis.
Claim 8
Dependent Claim
57 words
A needle as recited in claim 6 wherein the blade on the groove side in the clearance above the eye spaced from said ramp is deflected toward the longitudinal axis to define an upper offset angle with the longitudinal axis, said upper offset angle being less than the angle made by said ramp with said longitudinal axis.
