Abstract
Abstract A needle for delivering filamentary material to work which is pierced by the needle. The needle has an elongated blade which terminates at one end in a sharp pointed tip which is adapted to puncture through the work while delivering the filamentary material thereto. The blade has opposed faces and fixedly carries at one of the latter faces a partition which extends longitudinally of the blade from the tip thereof and which is situated between the opposed side edges of the blade. The partition terminates in an outer free edge which is inclined to and merges with the tip of the blade, and this partition is formed in the region of the tip with an open eye which contains the filamentary material and is designed to allow free access to the material and within which the filamentary material is adapted to extend. Just rearwardly of the open eye the partition carries at opposite sides thereof a pair of tubular guides for the filamentary material so that these tubular guides prevent direct contact between the filamentary material and the work until the needle is withdrawn from the work.

Claim 1
Independent Claim
204 words
A needle comprising an elongated blade 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 blade having a pair of opposed faces, a partition fixed to said blade at one of said faces thereof, extending longitudinally along said one face of said blade between opposed side edges of said blade and rearwardly from said tip thereof, said partition being perpendicular to said one face of said blade and terminating distant from said one face of said blade in an elongated free edge which in the region of said tip is inclined toward and merges into said tip, said partition being formed in the region of said tip with an eye through which the filamentary material is adapted to extend, and said partition having a pair of opposed side faces which respectively carry to the rear of but adjacent said eye a pair of elongated tubular filament guides which extend with said partition longitudinally of said blade and which are adapted to contain the filamentary material to guide the latter while preventing direct contact between the filamentary material and the work until the needle is withdrawn from the work.
Claim 2
Dependent Claim
204 words
A needle comprising an elongated blade 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 blade having a pair of opposed faces, a partition fixed to said blade at one of said faces thereof, extending longitudinally along said one face of said blade between opposed side edges of said blade and rearwardly from said tip thereof, said partition being perpendicular to said one face of said blade and terminating distant from said one face of said blade in an elongated free edge which in the region of said tip is inclined toward and merges into said tip, said partition being formed in the region of said tip with an eye through which the filamentary material is adapted to extend, and said partition having a pair of opposed side faces which respectively carry to the rear of but adjacent said eye a pair of elongated tubular filament guides which extend with said partition longitudinally of said blade and which are adapted to contain the filamentary material to guide the latter while preventing direct contact between the filamentary material and the work until the needle is withdrawn from the work.
Claim 3
Dependent Claim
19 words
The combination of claim 1 and wherein said eye extends through and interrupts said free edge of said partition.
Claim 4
Dependent Claim
62 words
The combination of claim 1 and wherein one of said tubular guides is in the form of a complete tube for completely enclosing the filamentary material while the other of said tubular guides is formed with an elongated outer cutout extending along the entire length of said other tubular guide so that the latter only partially encloses the filamentary material passing therethrough.
Claim 5
Dependent Claim
40 words
The combination of claim 1 and wherein one of said tubular guides is formed at is end which is closest to said open eye, directly next to said partition, with an elongated notch for facilitating access to the filamentary material.
Claim 6
Dependent Claim
29 words
The combination of claim 1 and wherein said blade has cutting edges respectively extending along said opposed side edges thereof and meeting at and forming part of said tip.
Claim 7
Dependent Claim
11 words
The combination of claim 1 and wherein said blade is flat.
Claim 8
Dependent Claim
15 words
The combination of claim 1 and wherein said free edge of said partition is rounded.
Claim 9
Dependent Claim
29 words
The combination of claim 1 and wherein said eye has a rounded edge around which the filamentary material is guided from one to the other of said tubular guides.
Claim 10
Dependent Claim
131 words
The combination of claim 1 and wherein said opposed side edges of said blade are in the form of sharp cutting edges which meet at said tip, said free edge of said partition being rounded and said eye extending through and interrupting said free edge of said partition to form an open eye, one of said tubular guides forming a complete tube for completely enclosing the filamentary material and the other of said tubular guides being formed with an elongated cutout extending longitudinally of said other tubular guide so that the latter only partially encloses the filamentary material, and said one tubular guide being formed at its end which is nearest to said eye with an elongated notch situated directly next to said partition for facilitating access to the filamentary material.
