Abstract

A gobo having linear motion is inserted to the narrow iris slot of a conventional ellipsoidal stage light. The linear moving pattern includes a housing, a drive roller and a motor, a return roller, and an endless pattern loop. The housing has a narrowed end for protruding into the instrument at the iris slot and holding the return roller on one side of the light. The housing has a broad end for mounting outside of the ellipsoidal stage light for holding the drive roller and motor at the other side of the light. The broad end of the housing has two spring-biased hinged clamps for clamping the linear moving pattern into a single unitary linear moving pattern iris insert. A first motor clamp holds the drive roller and motor in place. A second pattern clamp tensions and dimensions the endless pattern loop for extension into and out of the iris slot of the ellipsoidal light. The endless pattern loop is first threaded to the return roller and the return roller mounted to the narrow end of the housing. The drive roller and motor is threaded to the endless pattern loop, placed into the housing at the broad end, and locked into place by the motor clamp. The tension clamp is dropped over the endless pattern loop to dimension and tension the endless pattern loop at two parallel and linear runs on opposite sides of the iris slot. The unitary linear moving pattern iris insert is inserted to ellipsoidal stage lighting instrument at the iris slot for operation.
