  • Patent number: 4280266
    Abstract: A toy device adapted for threading beads upon a thread or line is disclosed. A container for beads is mounted to a preferably transparent chassis. The container has an outlet port or hole in a lower part thereof through which beads may fall out of the container one-by-one. A first end of the guide wire or like member is mounted substantially in the center of the outlet port. The container is continuously shaken through a hand actuated crank and ratchet gear assembly. As a result of the shaking, the beads undergo a random motion which eventually causes the beads to fall one-by-one through the outlet port onto the guide wire with the guide wire substantially centered in the central aperture of each bead. A bead advancing assembly which comprises two rotatable members having cut-away portions to capture the beads, is operatively associated with an intermediate portion of the guidewire.
