  • Patent number: 5431378
    Abstract: A method and an article for assembling a compression die spring in a spring pocket formed in a die member includes a retainer having an outer edge that is larger in width than the diameter of the sidewall of the spring pocket in order to form an interference fit with the sidewall and, thereby, retains a spring, a portion of which is spanned by the member in the spring pocket. The retainer has four legs whose distal ends are on a circle whose diameter is larger than the diameter of the pocket sidewall. At least two of the legs are configured to straddle a turn of the spring to allow the retainer to be juxtaposed with the spring with all four legs extending outwardly from the spring to engage the pocket sidewall. In one embodiment, the outer edge of the retainer is turned in order to accommodate variations in diameter of the pocket sidewall.

  • Patent number: 4916798
    Abstract: Applique or similar object is simultaneously formed and affixed to a baseplate by juxtaposing a plate of contributing material adjacent the baseplate and forcing a punch entirely through the contributing material to shear the object from the plate of contributing material. The object, in turn, shears a slug from the baseplate, which is positioned against a die opening, forming an opening in the baseplate in which the object is retained by interference fit. The method may be used to affix objects from a contributing material that is either harder than or softer than the baseplate material.
