Patent ID: 7594789

Claim:
An overhead carrier support adapted to support a substrate carrier having an overhead transfer flange, the overhead carrier support comprising: a support plate including a top and bottom surface; at least one coupling clamp fixed to the support plate and extending upwardly from the top surface, the at least one coupling clamp adapted to couple the overhead carrier support to a moveable track of an overhead transfer conveyor; a first side; a second side opposite the first side; a first blade receiver fixed below the support plate and including an upward facing groove, the first blade receiver and the upward facing groove further extending along the first side and adapted to receive a downwardly extending first blade of the overhead transfer flange of a substrate carrier; and a second blade receiver fixed below the support plate and including an upward facing groove, the second blade receiver and the upward facing groove further extending along the second side and adapted to receive a downwardly extending second blade of the overhead transfer flange of a substrate carrier; wherein the first blade receiver and the second blade receiver are angled at a third angle relative to each other such that the first blade receiver is oriented non-parallel to the second blade receiver and are adapted to allow a blade edge of the first blade and a blade edge of the second blade of the overhead transfer flange to settle into the first blade receiver and the second blade receiver, respectively, by a force of gravity.
