Multipurpose double acting drum pedal

A double acting drum beater device having a beater adapted to strike an adjacent drumhead once for each downward movement of a foot operated pedal, and then a second time under direct control of the foot pedal during subsequent upward return movement of the pedal, said drum beater device comprising at least one beater arm arranged to swing in an arc about a rotatable axis, said rotatable axis being defined by a shaft supported by mounting means, which shaft is arranged to undertake oscillatory type rotational movements, an arm affixed to said shaft in an offset relation to said shaft, a pivotally mounted foot pedal operatively disposed adjacent said mounting means and having up and down movements in response to foot motion, a connecting link of rigid construction pivotally connected at its one end to a toe portion of said foot pedal, and pivotally connected at its other end to the end of said offset arm, said foot pedal, when its toe portion is in an upward position, having an angular relationship to the plane of said link, with the end of the link connected to the foot pedal being higher than the end connected to said offset arm, said foot pedal, when pushed downwardly, moving with respect to said link such that the planes of the pedal and link are momentarily in alignment, with the pedal and link thereafter moving to a position below the aligned positon, said pedal, acting through said rigid link, bringing about shaft oscillation and therefore the beater striking the drumhead during each downstroke as well as during each upstroke of said pedal, and in doing so moving through momentary positions of alignment with said link during motion in each direction.

A double acting drum beater device having a minimum number of functioning parts and utilizing beaters adapted to strike an adjacent drumhead once for each downward movement of a foot-operated pedal, and then a second time during the subsequent upward return movement of the pedal, said drum beater device comprising a pair of essentially parallel beaters each arranged to swing in an arc about a rotatable axis, said rotatable axis being defined by a shaft supported by mounting means, which shaft is arranged to undertake oscillatory type movements about its longitudinal axis, an arm attached to said shaft in an offset relation thereto, a foot pedal mounted adjacent said mounting means and having up and down operative movements, connecting link means of rigid construction pivotally connected to a toe portion of said foot pedal and pivotally connected to said offset arm, such that up and down movements of the toe portion of said pedal cause, through the dual pivot arrangement, said connecting link and said arm to move responsively and thus cause said shaft to oscillate in a rotary manner, said shaft rotating in a first direction and then in the opposite direction about its longitudinal axis during downward movement of said pedal, and thereafter rotating in both directions during the ensuing upward movement of the pedal, and means interconnecting said shaft and said beaters such that each of said beaters is caused by such shaft oscillations to strike an adjacent drumhead twice for each up-down cycle of said pedal.

A double acting drum beater device utilizing beaters adapted to strike an adjacent drumhead once for each downward movement of a foot-operated pedal, and then a second time during the subsequent upward return movement of the pedal, said drum beater device comprising a pair of beaters arranged to swing in an arc about a rotatable axis, said axis being defined by a shaft supported by mounting means, which shaft is arranged to undertake oscillatory type rotary movements about its longitudinal axis, at least one of said beaters being supported by a mount allowing for flexibility, the mount for each beater being secured to a separate sleeve disposed on said shaft, each of said sleeves being slidable along said shaft between operative and inoperative positions at the behest of an operator, with each sleeve being rotatable with said shaft only when it is in the operative position, a foot pedal mounted adjacent said mounting means and having up and down operative movements, an arm attached to said shaft in an offset relation thereto, connecting link means of rigid construction connecting a toe portion of said foot pedal to said arm, such that up and down movements of the toe portion of said pedal cause said connecting link and said arm to move responsively and thus cause said shaft to oscillate, said shaft rotating in a first direction and then in the opposite direction about its longitudinal axis during downward movement of said pedal, and thereafter rotating in both directions during the ensuing upward movement of the pedal, each of said beaters being caused by such shaft oscillations to strike an adjacent drumhead twice for each up-down cycle of said pedal when said sleeves are in said operative positions.

A double acting drum beater device having a beater adapted to strike an adjacent drumhead once for each downward movement of a foot operated pedal, and then a second time under direct control of the foot pedal during subsequent upward return movement of the pedal, said drum beater device comprising at least one beater arm arranged to swing in an arc about a rotatable axis, said rotatable axis being defined by a shaft supported by mounting means, which shaft is arranged to undertake oscillatory type rotational movements in response to foot pedal movements, a flexible spring-biased beater mount effectively mounted on said shaft so as to rotate therewith, a portion of said beater mount forming a support for said beater arm, an elongate arm affixed to a mid portion of said shaft in an offset relation thereto, said foot pedal having a pivotal support about which it is rockable so as to bring about up and down movements of a toe portion of said pedal, connecting link means of rigid construction pivotally connecting said toe portion of said foot pedal to said elongate arm, such that up and down movements of said toe portion cause said connecting link and said elongate arm to move responsively and thus to cause said shaft to oscillate rotationally, the flexible character of said beater mount permitting a controlled amount of overtravel of said shaft after said beater has struck the adjacent drumhead, and means for adjusting the strength of the spring bias of said beater mount.
