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: A knockdown spring unit for seating furniture has lift springs connectible to a rail of a frame of the furniture and releasably attachable to a suitable platform arrangement forming a seating surface. The platform arrangement can either be fastened directly to the frame at points opposite connection of the lift springs to the frame, or the platform arrangement can be supported entirely by the lift springs for indirect attachment to the frame. Each of the lift springs has a coil portion which terminates at a one end thereof in an eye and at the other end thereof in a stem disposed extending transversely from the turns of the coil portion and forming a hook provided with a substantially V-shaped bend the vertex of which is normally disposed adjacent the eye of the spring when the spring is in an undeflected state.
Abstract: A metallic clip designed for holding the end bar of a sinuous cushion-supporting spring in position on one rail of an article of furniture and also having associated therewith jaw portions which straddle the rail and, when pressed inwardly against the rail, seize the sides of such rail and maintain the clip firmly in position on the rail. In one form of the invention, a string of such clips are held together in slightly spaced side-by-side fashion by a liner strip which is seated within the reentrant or reverse bends of the clips so that individual clips may be successively severed from the strip for application to the rail. In a modified form of the clip, means are provided whereby the clips may be stacked together loosely against complete separation so that individual clips may be successively removed from the stack at will for rail application.
