3 claims: 3 independent, 0 dependent

  1. 1
    What is claimed as new is as follows:1. A toy or amusement device, comprising: an elongated shaft, handle means at the ends of said shaft facilitating manual gripping and axial movement thereof, means defining the inward extent of said handle means, compression springs spaced inwardly of said defining means, and a hollow sphere slidable on said shaft between said compression springs in response to manually exerted 3,545,121 forces, said handle means comprising a series of indentations made in the circumference of the shaft, said defining means beng snap washers inserted in slots cut into the circumference of the shaft, said slots and said indentations being of a uniform depth and opposite each other, said slots being of the kerf type, said compression springs having a slightly larger inside diameter than said shaft diameter, and placed thereon in abutting relation to the defining means, said compression springs being of the coil-type with an end convolution of lesser diameter than the shaft which clampingly engages said shaft at the end of the spring abutting said defining means and the opposite end being free for compression.
  2. 2
    A manually manipulated amusement device comprising an elongated rigid shaft having a central portion, a sphere freely reciprocally mounted on the central portion of said shaft, energy storing and releasing means carried by said shaft at each end of the central portion in position for engagement by said sphere when approaching the end of movement in one direction for stopping the sphere while storing the kinetic energy and accelerating the sphere in the opposite directon by applyng the stored kinetic energy to the sphere, axial handle means at each end of said shaft by which the shaft may be grasped and moved longitudinally to initially move said sphere axially of said shaft into engagement with said energy storing and releasing means and subsequently increase the velocity of the sphere by axially moving said shaft in relation to the sphere, wherein said handle means includes a series of indentations formed in the circumference of the shaft, a washer at the inner end of each handle means defining the inward extent of said handle means, said energy storing and releasing means includes a coil compression spring having an inside diameter slightly larger than the shaft diameter and disposed in encircling relation on the shaft with the outer end of each spring abuttingly engaging the washer, the outer end convoluton of each spring having a diameter less than the diameter of the shaft and clampingly engaging the shaft for retaining the spring against the washer with the inner end of each spring being free of the shaft for compression.
  3. 3
    The structure as defined in claim 2 wherein the inner ends of the springs on the shaft are spaced apart a distance substantially greater than the diameter of the sphere thereby enabling movement of the sphere between the inner ends of the springs during reciprocation thereof with the compression springs cushioning movement of the sphere when decelerating the sphere and then accelerating the sphere in the opposite direction.
