  • Patent number: 4450666
    Abstract: The specification describes a bricking ring for use in positioning and temporarily retaining bricks in a circular overhead configuration. The bricking ring intended for use in lining kilns comprises a plurality of arcuate segments forming a semi-circular configuration. The segments are pivotally interconnected, and are attached to a central rigid support by means of arms the length of which is adjustable. Thus, the radius of the semi-circular configuration may be adjusted so that the bricking ring may be used in different diameter kilns or when the kiln is lined with a double layer of bricks.
