Abstract (en)
[origin: US4929177A] An especially adapted kiln car transfer apparatus includes a transfer carriage for supporting at least one kiln car. The transfer carriage itself is supported upon transverse tracks (i.e., relative to the longitudinal dimension of the tunnel kilns with which the transfer apparatus is associated) so as to be capable of movements between adjacent ends of a pair of tunnel kilns. A generally inverted U-shaped housing is carried by the transfer carriage and defines an interior space sized and configured to accept a kiln car. A reciprocally movable wall structure is disposed within the housing's interior space. The wall structure may thus move between the opposing open ends of the housing in response to the continual advancement of the kiln car onto the transfer carriage, and hence, into the interior space defined by the housing. In such a manner, the movable wall minimizes heat build-up within the transfer apparatus, since only a minimal region of the transfer apparatus is exposed directly to heat radiating from the ware at any give time during the transfer operation. Preferably, transverse seals are associated with the movable wall structure and are adapted to provide a thermal barrier between the kiln car and the carriage assembly.
