Abstract: A spring attachment clip for the fastening of springs to furniture frames, the clip carrying its own means for being secured to the frame and having in addition means for reducing or eliminating audible noise as ordinarily caused by the action of the spring working against the clip. The clip configuration is adapted to permit its multiple formation in long strips intended to be fed into an automatic device which separates the individual clips from the strips and secures them to the frame. Additionally, the U-shaped edges of the spring engaging end of the clips are bevelled outward to strengthen the clip rendering it unnecessary to close the clip to prevent its opening under spring tension.

Abstract: An automatic means for the attachment of spring clips to wooden frame members of furniture which clips serve in the attachment of springs to the frame. The clips are preformed in long coiled strips and are fed therefrom into a pneumatic driving tool which separates individual clips from the strip and drives their pointed ends into the frame members at controlled spaced intervals as the frame member is fed past the driving tool.
