Definitions

  • the two flat surfaces 16 are formed on an inverted, generally U-shaped (in transverse vertical crosssection) member16A as best shown in FIG. 4.
  • the upper end of the arm 12 is disposed between the depending portions of the member 16A, and the lower end of the arm 12 is disposed within a guide slot 17 formed in a base 18.
  • the upper end of a vertical stand 19 supports the member 16A while the lower end of the stand 19 is supported by the base 18.
  • this embodiment of the invention there is a catch 13 fixed in the base 18 of the embodiment, designed to mate with a hook or the like on the end of the arm 12.
  • This catch defines the initial displacement of the pendulum and thereby fixes the time for motion of the pendulum for a given position of the weight on the arm.
  • the magnitude of the weight and its position on the arm may be varied thereby allowing, theoretically, infinite variation in the lengths of time for oscillation.
