Abstract

A tufting machine hook with a spring clip secured at one end to the hook shank is resiliently engaged on a face of the bill by a flag on the clip adjacent the other end. An intermediate portion of the clip is bent so as to be disposed out of the plane of the face engaged and toward the opposite face. In one embodiment the face to which the clip is secured and the face engaged by the flag are on the same side and the free end of the clip is elongated. In the other embodiment the clip is secured to the shank at the opposite side to the face engaged by the flag and the clip is bent to cross the plane of the hook.

Claims

1. In combination, a hook and spring clip for use in a tufting machine, said hook being planar and comprising a shank having a mounting portion and a bill extending therefrom to define a throat therebetween, said bill having a top edge and a bottom edge extending from said throat to form a nose, said spring clip having one end secured to the shank and extending to a free end through an intermediate portion generally in spaced parallel relation to said bill, a flag adjacent the free end resiliently engaging said nose at one face of said hook, said flag being defined by a pair of webs converging at a crease in said clip, a first of said webs extending toward said free end, the other of said webs extending toward said intermediate portion and merging into said intermediate portion at an angle, said intermediate portion being disposed beneath said bill and spaced out of the plane of said one face of said hook engaged by said flag toward the other face of said hook.

2. In the combination recited in claim 1 wherein said intermediate portion is disposed intermediate the planes of the sides of said hook.

3. In the combination as recited in claims 1 or 2 wherein said first of said webs terminates in a nose at the free end of the clip, said nose being elongated from said first web to said free end.

4. In the combination as recited in claim 1 wherein said clip is secured to said shank on one face thereof, said intermediate portion is disposed in a plane substantially co-planar with said one face of said shank, and said one face of the shank being the face opposite to the face of the bill engaged by said flag.

5. In the combination as recited in claim 4 wherein said other of said web is bent at a first angle to form a part thereof substantially parallel to said intermediate portion.

6. In the combination as recited in claim 5 wherein said part of said web parallel to said intermediate portion extends beyond the nose of said hook relative to said shank, and said web has a second part thereof at an angle to said first part and crossing the planes of the faces of said hook to merge with said intermediate portion.
