  • Patent number: 10269334
    Abstract: A cam operated drum tuning system which is rotatable clockwise and counterclockwise to tunes a musical drum. A cam ring mechanism employs multiple helical tracks. A removable radius plate and tool facilitates rotation. The timing system may be attached directly to drum lugs, to a retrofit ring attached to the lugs, or to a full floating I or II framework which use edge or full floater rings, and/or adjustable pull rods to connect the top and/or bottom tuning systems so that nothing need contact the drum shell. Eccentric micro tuners adjust the rim rollers which ride on the inner hoop, which has a lip on the underside to add overlap. Elevators are fused to raise and/or lower the cam ring to align it perpendicular to the bearing edge of the drum shell.

  • Patent number: 9053685
    Abstract: Methods and devices for attaching a one touch tuning system to different drum types. Components preferably include a retrofit ring for fitting the one touch tuning system to a lug style drum, and elevators to attach and adjust the height of the tuning system on the drum. On full floating drums, a framework is provided so that no hardware need be attached to the drum's shell. Framework may also include adjustable pull rods which can attach a tuning system on one end of the drum to another tuning system on the opposite end. Twisting the adjustable pull rods one direction extends the length of them, twisting the opposite direction retracts them thereby shortening the overall length of the framework in relation to the depth of the drum shell. Offset rim rollers help align the inner hoop and rotating actuator rings to offer more precise tuning and free movement.

  • Patent number: 7501567
    Abstract: A drum tuning system which rotates clockwise or counterclockwise to adjust the tension of a drum head fitted over the open end of a drum body. It utilizes a rotating ring having numerous opposing equally spaced vertically projecting tabs along the top of the body's diameter, each with inward facing wheels that ride on the horizontal surface of a separate inner hoop bearing down on the drum head. The rotating actuator ring is fitted with multiple radial cleats projecting from its outside diameter for grasping it. A radius plate having horizontal holes extends from the drum body, and a tool engages the radial cleats on the rotating actuator ring to facilitate rotation. Multiple adjustable eccentric lugs are used to raise and lower the drum camming mechanism in relation to the open end of the drum body where attached. Horizontal projecting links support the drum attached to suspension mounting systems.
