  • Patent number: 5266733
    Abstract: A high hat includes a ground supported stand with a vertical hollow tube through which a cymbal rod is operably mounted. A lower cymbal is mounted on the upper end of the tube with an upper cymbal connected to the upper end of the cymbal rod such that vertical movement of the cymbal rod will cause the upper and lower cymbals to contact one another for a percussive sound. A spring is connected to the cymbal rod to bias the rod into its upper position, wherein the upper cymbal is spaced upwardly away from the lower cymbal. An operable foot pedal is utilized to move the cymbal rod and cause the upper and lower cymbals to contact one another. The foot pedal includes a foot plate pivotally connected at a heel end to a base. A pair of sprockets are connected together and rotatably mounted on a shaft above the toe end of the foot plate.
