Abstract
Abstract A needle which includes an elongated body formed with a front pointed tip for piercing through the work as well as with a pair of bores rearwardly of the tip for receiving the filamentary material. The body is formed at the front ends of these bores with a transverse notch which forms an open eye so that the filamentary material can extend forwardly along the interior of one of the bores, across the open eye, and then rearwardly along the interior of the other bores enabling the needle in this way to pierce through the work while maintaining the filamentary material out of engagement with the work.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
137 words
A needle comprising an elongated body having a longitudinal central axis and terminating at one end in a sharp, pointed tip for puncturing through work to which filamentary material is to be delivered by the needle, said body being formed on opposite sides of a plane which contains said axis with a pair of longitudinally extending bores and in the region of said tip with a transverse notch forming an open eye and communicating with front ends of said bores so that filamentary material may extend forwardly through one of said bores, across said open eye, and then rearwardly through the other of said bores, so that when said tip pierces through work the filamentary material will not engage the work and so that a loop can be pulled from Said body at said open eye thereof.
Claim 2
Dependent Claim
137 words
A needle comprising an elongated body having a longitudinal central axis and terminating at one end in a sharp, pointed tip for puncturing through work to which filamentary material is to be delivered by the needle, said body being formed on opposite sides of a plane which contains said axis with a pair of longitudinally extending bores and in the region of said tip with a transverse notch forming an open eye and communicating with front ends of said bores so that filamentary material may extend forwardly through one of said bores, across said open eye, and then rearwardly through the other of said bores, so that when said tip pierces through work the filamentary material will not engage the work and so that a loop can be pulled from Said body at said open eye thereof.
Claim 3
Dependent Claim
23 words
The combination of claim 1 and wherein said elongated said body is of a circular cross-section in any plane transverse to said axis.
Claim 4
Dependent Claim
35 words
The combination of claim 1 and wherein said body is formed along at least one side surface with a longitudinal opening extending through a wall of said body and communicating with one of said bores.
Claim 5
Dependent Claim
22 words
The combination of claim 3 and wherein said opening extends from said open eye along the entire length of said one bore.
Claim 6
Dependent Claim
33 words
The combination of claim 3 and wherein said body is provided along part of at least one edge which defines part of said opening with a cutting region for cutting the filamentary material.
Claim 7
Dependent Claim
31 words
The combination of claim 5 and wherein said body is formed along both edges between which said opening extends respectively with a pair of cutting regions for cutting the filamentary material.
Claim 8
Dependent Claim
50 words
The combination of claim 1 and wherein said body is formed in said plane on one side of said transverse notch which forms said open eye with an additional notch communicating with said open eye for facilitating grasping of the filamentary material in said open eye to form a loop.
Claim 9
Dependent Claim
65 words
The combination of claim 7 and wherein said body is formed in said plane with a pair of said additional notches respectively situated before and behind said transverse notch which forms said open eye and both communicating with said transverse notch for facilitating grasping of the filamentary material in the open eye either from the front of the filamentary material or from the rear thereof.
Claim 10
Dependent Claim
33 words
The combination of claim 8 and wherein said body is formed in said plane with an intermediate notch portion deeper than said transverse notch, extending across the latter, and interconnecting said additional notches.
Claim 11
Dependent Claim
74 words
The combination of claim 9 and wherein said elongated body is of a circular cross-section and has to the rear of said tip thereof a substantially constant diameter while said body gradually tapers from its constant diameter portion up to said tip thereof, and all of said notches being situated at a region of said body which is adjacent the constant diameter portion thereof where the body starts to taper toward the tip thereof.
