  "title": "How Walter Hunt Invented the Modern Safety Pin",
  "original_title": "Walter hunt",
  "summary": "Walter Hunt's 1849 patent for a simple, coiled wire device that keeps sharp points covered while fastening fabric.",
  "what_it_does": "The device consists of a single piece of wire bent into a spring-like coil at one end. This coil provides the tension necessary to keep the pin closed. The other end features a protective sheath or guard that covers the sharp point of the pin when it is snapped into place. This mechanism allows the pin to pierce fabric and remain securely fastened without pricking the user.",
  "what_it_does_not_cover": [
    "Does not cover straight pins lacking a protective clasp mechanism.",
    "Does not cover buttons, zippers, or other types of mechanical fasteners.",
    "Does not cover the use of multiple materials, as the patent specifically details a single continuous wire structure."
