  "kind": "A",
  "title": "Automatic vending machine",
  "abstract": "By displaceably, rather than fixedly, supporting selected track segments in the gravity-fed storage chamber of an automatic vending machine, the kinetic energy developed in the stored goods as they fall in the storage chamber is dissipated by the displaceable track segments in a damping fashion and the goods are not subject to shock and damage.",
  "claims": [
    "1. A machine for automatically dispensing, goods, including: a serpentine-shaped vertical storage chamber for said goods, said chamber having an inlet and an outlet; said serpentine-shaped vertical storage chamber being formed by a series of vertically disposed, individually supported, horizontally-spaced and opposed arcuate track segments and a cooperating pair of side-plates; selected ones of said track segments being pivotally supported at their upper ends for rotation when engaged by said goods; said horizontally-spaced track segments being directly opposed.",
    "2. A machine for automatically dispensing goods, including: a serpentine-shaped vertical storage chamber for said goods, said chamber having an inlet and an outlet; said serpentine-shaped vertical storage chamber being formed by a series of vertically disposed, individually supported, horizontally-spaced and opposed arcuate track segments and a cooperating pair of side-plates; selected ones of said track segments being pivotally supported at their upper ends for rotation when engaged by said goods; said machine including, in addition, stop means supported proximate to the lower portion of each of said selected ones of said track segments for limiting the displacement thereof.",
    "3. A machine for automatically dispensing goods, including: a serpentine-shaped vertical storage chamber for said goods, said chamber having an inlet and an outlet; said serpentine-shaped vertical storage chamber being formed by a series of vertically disposed, individually supported, horizontally-spaced and opposed arcuate track segments and a cooperating pair of side-plates; selected ones of said track segments being pivotally supported at their upper ends for rotation when engaged by said goods; said horizontally-spaced track segments being partially opposed.",
    "4. A machine for automatically dispensing goods, including: a serpentine-shaped vertical storage chamber for said goods, said chamber having an inlet and an outlet; said serpentine-shaped vertical storage chamber being formed by a series of vertically disposed, individually supported, horizontally-spaced and opposed arcuate track segments and a cooperating pair of side-plates; selected ones of said track segments being pivotally supported at their upper ends for rotation when engaged by said goods; said selected ones of said track segments being pivotally supported above and proximate to their respective centers of gravity and each having a mass approximating that of one item of said goods, whereby selected ones of said arcuate track segments hang into the normal passage for said goods and dissipate the kinetic energy of each unit of said goods as it moves through such passage.",
    "5. Apparatus according to claim 4 which includes, in addition, a weight attached to each of said selected ones of said track segments to increase the effective mass of each such track segment.",
    "6. A machine for automatically dispensing goods, including: a serpentine-shaped vertical storage chamber for said goods, said chamber having an inlet and an outlet: said serpentine-shaped vertical storage chamber being formed by a series of vertically disposed, individually supported, horizontally-spaced and opposed arcuate track segments and a cooperating pair of side-plates; selected ones of said track segments being pivotally supported at their upper ends for rotation when engaged by said goods; said machine including, in addition, spring means coupled to said selected ones of said track segments for biasing said selected ones of said track segments towards said opposed arcuate track segments and into the path of said goods; the mass of each of said selected ones of said track means in combination with the force of said biasing spring approximating the force exerted by units of said goods passing through said storage chamber."
