Adjustable drum beating apparatus

1. An adjustable drum beating device, comprising, in combination,

a) at least one rotor operable to rotate a drum beater,

b) a foot pedal driven flexible driver having a path of engagement with the rotor and operable to rotate the rotor, the driver having adjustable connection to the rotor to effectively adjust the position of the foot pedal relative to the rotor,

c) there being adjustably relatively movable parts assembled as parts of the rotor to adjust the configuration of said path of engagement of the flexible driver with the rotor, the driver engaging both of said parts, one of said parts being a pusher locally peripherally bounded by the driver so as to push the driver outwardly as said one part is moved relative to another said part, there being guide means to enable guided bodily displacement of said one part outwardly relative to said other part and retention means to then retain said one part in a selected outwardly displaced position, relative to said other part.

2. The combination of claim 1 wherein said retention means comprises a threaded fastener retained by at least one of said parts.

3. The combination of claim 1 wherein said retention means includes a clamp to clamp together said parts after adjusted relative movement of the parts.

4. The combination of claim 3 wherein said clamp projects in a direction generally parallel to an axis defined by said at least one rotor.

5. The combination of claim 1 wherein said adjustable connection of the driver to the rotor includes a releasable clamp retaining an end portion of the flexible driver to said rotor, and spaced from said retention means.

6. The combination of claim 1 wherein said adjustable movable parts have adjustable slide interconnection.

7. The combination of claim 1 wherein said adjustably movable parts have adjustable pivotal interconnection.

8. The combination of claim 1 including a tension spring urging the rotor toward a rest position, the spring having an end portion remote from the rotor, and a swivel connection between said spring end portion and a support.

9. The combination of claim 1 including a base plate, at least one pedestal on a base plate, an axle carried by the pedestal, and defining an axis, the rotor carried by the axle to rotate about said axis, the foot pedal carried to pivot relative to the base plate.

10. An adjustable drum beating device, comprising

a) at least one rotor operable to rotate a drum beater,

b) a foot pedal driven flexible driver having a path of engagement with the rotor and operable to rotate the rotor, the driver having adjustable connection to the rotor to effectively adjust the position of the foot pedal relative to the rotor,

c) there being adjustably relatively movable parts associated with said at least one rotor to adjust the configuration of said path of engagement of the flexible driver with the rotor, the driver engaging both of said parts,

d) said adjustable connection of the driver to the rotor including a releasable clamp retaining an end portion of the flexible driver to said rotor,

e) said releasable clamp includes adjustably interengagable teeth carried by said rotor and by said flexible driver.

11. The combination of claim 10 wherein the releasable clamp also includes a fastener operable to hold said teeth in interengagement.

12. An adjustable drum beating device, comprising

a) at least one rotor operable to rotate a drum beater,

b) a foot pedal driven flexible driver having a path of engagement with the rotor and operable to rotate the rotor, the driver having adjustable connection to the rotor to effectively adjust the position of the foot pedal relative to the rotor,

c) the rotor having relatively adjustable movable sections which are interconnected in selected relative positions in which the driver is held Pushed relatively away from the rotor, and one section is pushed outwardly relative to the other section, to shorten the effective length of the driver,

d) and retention means for retaining said sections in said selected relative positions.

13. adjustable drum beating device, comprising

a) at least one rotor operable to rotate a drum beater,

b) a foot pedal driven flexible driver having a path of engagement with the rotor and operable to rotate the rotor,

c) there being adjustably relatively movable parts assembled and connected as parts of the rotor to adjust the configuration of said path of engagement of the flexible driver with the rotor,

d) one of said Parts peripherally bounded by the driver so as to push the driver outwardly,

e) and retention means for returning said parts in selected relative positions, in which one part is replaced displaced outwardly away from an axis defined by the rotor.
