Patent ID: 7183680

Claim:
An apparatus comprising: a mounting rod; a rotatable hub rotatably mounted on the mounting rod, the hub comprising: a platform; an electrical contact track comprising first and second generally circular contacts fixed to the platform; and a central wheel fixed relative to the platform and aligned with the electrical contact track; the apparatus further comprising: a transverse support mounted to and rotatable with the rotatable hub, wherein the transverse support is perpendicular to the mounting rod and comprises first and second distal mounts spaced radially from the rotatable hub; first and second electrical devices respectively mounted at the first and second distal mounts of the transverse support; first and second leads respectively connected to the first and second electrical devices and to the first and second generally circular contacts; a power supply fixedly mounted to the mounting rod, the power supply comprising first and second conductors spaced radially from the mounting rod and respectively contacting the first and second generally circular contacts; a drive wheel spaced radially from the mounting rod and drivingly coupled to the rotatable hub central wheel; a motor fixedly mounted to the mounting rod and driving the drive wheel, whereby the first and second electrical devices are capable of receiving power from a fixedly mounted power supply while the electrical devices rotate about the mounting rod as the fixedly mounted motor causes the rotatable hub to rotate.
