Abstract

A combination cut/loop hook and clip for tufting machines in which the mounting portion of the hook remote from the beak includes a longitudinal groove for receiving the tail portion of the clip. The groove includes a pair of female formations in the form of holes for receiving corresponding male formations on the clip tail portion in a detachable press-fit relationship. The spacing between the formations are such that the crease of the enlarged portion of the clip properly resiliently engages the beak. A worn clip may be readily removed from the hook and replaced by another clip without discarding a useable hook.

Claims

1. A combination cut/loop hook and clip for a tufting machine, said hook comprising a substantially planar body member including a blade and a shank, said blade extending forwardly from the shank and terminating at a loop seizing beak, an elongated mounting portion extending rearwardly from the shank for mounting within the tufting machine, a neck defining a reference surface formed at the rear of said blade above the shank and at least another reference surface formed on the upper edge of the mounting portion substantially normal to the neck, an elongated groove formed in one planar surface of the mounting portion, said clip comprising an elongated member having an enlargement at one end thereof and a substantially planar tail portion extending therefrom, at least a substantial part of said tail portion being of a width and thickness receivable within said groove so that a surface of said mounting portion within said groove and a surface of said part form corresponding abutting surfaces, and the opposite surface of said part forms a substantially smooth coplanar continuation of said planar surface, protuberence means defining at least one male formation on one of said corresponding abutting surfaces, recess means defining a like number of female formations in the other of said corresponding abutting surfaces, said female formations being of a size to cooperatively and securely receive a respective male formation, said enlargement having a crease disposed out of the plane of said tail and said groove and said formations being disposed such that said tail portion is spaced from said blade and said crease resiliently engages said beak.

2. The combination as recited in claim 1, wherein said protuberence means is formed on said tail and said recess means is formed in said groove.

3. The combination as recited in claim 2, wherein there are two male formations and two female formations, each like formation being spaced apart an equal amount.

4. The combination as recited in claim 3, wherein said female formations are holes extending through said mounting portion.

5. The combination as recited in claim 2, wherein said male and female formations are of a size such that they may be press-fit together and readily detached.

6. The combination as recited in claim 5, wherein there are two male formations and two female formations, each like formation being spaced apart an equal amount.

7. The combination as recited in claim 6, wherein said female formations are holes extending through said mounting portion.
