  • Tremolo block
    Patent number: 8008559
    Abstract: A tremolo assembly includes a metallic block having an upper end near a pivoting mounting point. The lower end of the block depends downwardly into a space within a guitar body. The tremolo block has a proportionately greater mass near the lower end relative to the upper end that enhances the “vibrato” effect of the tremolo assembly.

  • Wheeled accessory for equipment stands
    Patent number: 5484154
    Abstract: A retractable wheeled accessory for equipment stands is disclosed as having a collapsible axle tube pivotally attached to two interface members which are removably attached to an equipment stand such as a tripod. Wheels are connected to the axle by way of offset crank members. Pivotal rotation of the axle tube by movement of a level arm causes the wheels to alternately engage and disengage a supporting surface. The invention can accommodate various positions of a tripod by adjusting the track of the wheel via the collapsible axle tube and by permitting the two interface members to pivot independently of the orientation of the axle tube.
