  "title": "Cutting device",
  "abstract": "A cutting device which retains a severed portion of an object between two jaws. The cutting device is a mechanism such as shears, clippers or cutters having a jaw and a blade which close against each other so as to cut an object, and a second jaw which moves as said blade moves so as to retain a severed portion of the object which has been cut between said jaws, keeping the severed portion from falling away.",
  "claims": [
    "1. A cutting device which will retain an object which has been severed, comprising: a. a first jaw; b. a blade attached to said first jaw which is in a pivotal relationship with said first jaw, wherein said blade closes against said first jaw so as to sever an object as said first jaw and said blade are pivoted toward each other; and c. a second jaw which is attached to said blade by means which allows said blade and said second jaw to pivot relative to each other about a common point, and wherein said blade and said second jaw are in a spring biased relationship by means of a coil spring located over said means which allows said blade and said second jaw to pivot relative to each other, so that as said first jaw and said blade are pivoted toward each other so as to close, a portion of said object which has been severed is retained between said first jaw and said second jaw by said spring biasing means.",
    "2. A cutting device as described in claim 1, wherein said means which allows said blade and said second jaw to pivot about a common point is a pin located through a void in said blade and in said second jaw, and wherein one end of said coil spring is mounted to said pin, with the opposite end of said coil spring mounted to a point on said second jaw.",
    "3. A cutting device which will retain an object which has been severed as described in claim 2, wherein said first jaw, said blade, and said second jaw are mounted to each other by a single, common pin which allows said first jaw, said blade and said second jaw to pivot about said common pin.",
    "4. A cutting device which will retain an object which has been severed, as described in claim 3, further comprising a protrusion from said second jaw located opposite a surface of said second jaw which faces said first jaw, and which contacts said blade so as to limit travel of said second jaw relative to said blade.",
    "5. A cutting device which will retain an object which has been severed, as described in claim 2, further comprising a protrusion from said second jaw located opposite a surface of said second jaw which faces said first jaw, and which contacts said blade so as to limit travel of said second jaw relative to said blade.",
    "6. A cutting device which will retain an object which has been severed as described in claim 1, wherein said first jaw, said blade, and said second jaw are mounted to each other by a single, common means which allows said first jaw, said blade and said second jaw to pivot about a common point.",
    "7. A cutting device which will retain an object which has been severed, as described in claim 6, further comprising a protrusion from said second jaw located opposite a surface of said second jaw which faces said first jaw, and which contacts said blade so as to limit travel of said second jaw relative to said blade.",
    "8. A cutting device which will retain an object which has been severed, as described in claim 1, further comprising a protrusion from said second jaw located opposite a surface of said second jaw which faces said first jaw, and which contacts said blade so as to limit travel of said second jaw relative to said blade."
