Apparatus for lining kilns, tunnels and the like

Apparatus for lining with brick a kiln, tunnel or like arcuate surface comprising a frame adapted to be mounted within the surface to be lined, means for mounting on said frame at least one arcuate member adapted to extend in spaced relation to the surface to be lined and adapted to locate and support a column, of brick substantially in the space between said member and said surface, said arcuate member comprising a continuous longitudinally deformable metal base strip supported on said frame, said base strip having flexible side bands bonded thereto to define a continuous trough that opens outwardly, an elongated tubular expansible member extending in overlying relation along said base strip so as to lie along the bottom of the trough, and a relatively solid flexible member loosely overlying said expansible member.
