Title: Case sealer base leveler

Abstract: A leveling or elevational positional adjustment system comprises a leg frame member, a leg extension member, and a leg extension stop member. The leg frame member comprises an external corner component having a substantially arcuate configuration, and an internal cross-plate component disposed across the interior of the corner component. The leg extension member has an arcuate cross-sectional configuration essentially matching that of the external corner component of the leg frame member so as to be disposed in surface-to-surface contact with the external corner component of the leg frame member when the leg extension is inserted into the leg frame member, and the leg extension stop member has an external arcuate cross-sectional configuration also substantially matching that of the leg extension member. An actuator screw is mounted upon the cross-plate component of the frame member and is engaged with the leg extension stop member so as to effectively force the leg extension stop member into surface-to-surface contact with the leg extension member such that the leg extension member is in turn forced into surface-to-surface contact with the leg frame member. The leg extension member is positionally adjusted to, and retained at, any particular longitudinal position with respect to the leg frame member simply by untightening the actuator screw, adjusting the disposition of the leg extension member relative to the leg frame member, and retightening the actuator screw.
