Patent ID: 8800754

Claim:
A conveyor system comprising: a. a plurality of first drive tube couplings, wherein each first drive tube coupling of the plurality of first drive tube couplings comprises i. a base portion, wherein the base portion comprises a face and a thickness, and ii. an elongated portion, wherein the elongated portion extends from the face of the base portion at a first end, wherein the elongated portion further comprises at least one rib extending from the face of the base portion toward a distal end of the elongated portion, wherein the elongated portion comprises a cross-section; b. a plurality of second drive tube couplings, wherein each second drive tube coupling of the plurality of second drive tube couplings comprises i. a coupling spacer, wherein the coupling spacer comprises a face and a thickness, and ii. a coupler, wherein the coupler comprises an elongated member that abuts the face of the coupling spacer and extends substantially perpendicular thereto, wherein the coupler comprises a cross-section, wherein the cross-section of the elongated portion is different than the cross-section of the coupler; wherein the thickness of the base portion of each of the first drive tube couplings is substantially equal to the thickness of the coupling spacer of each of the second drive tube couplings.
