Abstract: A kiln car superstructure is formed by inserting horizontal tying members into openings in hollow vertical support posts and interlocking the tying members within the posts. Two tying members are inserted into opposite openings in each post with each member extending to approximately the post center. Apertures through the tying members are located within the post interior when the tying members are positioned to form the superstructure. Locking pins are inserted into the apertures in the tying members and wedges are then inserted between the ends of the tying members. The wedges force the tying members apart which in turn force the locking pins against the interior of the post. The posts comprise sections which are stably stacked by means of post couplers having a center section sized to conform to the exterior of the post sections with reduced extensions on either side to enter the hollow interiors of the post sections.
Abstract: A framework for supporting ware to be kiln fired is constructed from a plurality of shelves or supporting arms which are engaged within horizontal slots in one or more vertical support posts. The shelves or supporting arms are secured to the support posts by locking pins which are inserted through apertures in the posts and shelves or support arms which apertures are aligned when the posts and shelves or support arms are properly engaged with one another. In an alternate embodiment, a supporting framework is constructed from vertical support members and support plates. Each vertical support member comprises a vertical support post preassembled with ware supporting arms which are interlocked to the post by a locking pin. Assembled vertical support members are received at either end by the support plates which include indentations for receiving the ends of the vertical support members.
