Abstract

Abstract A power file with a plurality of pans which are mounted on an endless conveyor for movement in a continuous orbit of travel. Side strut column members having upper and lower box members support the pans and conveyor mechanism. The pans each have a reinforced back wall with a plurality of gussets hung from the back wall which support a single thickness bottom wall eliminating bottom wall reinforcing members. A box trim bead is formed at the front edge of the bottom wall to provide stiffness for the bottom wall and to trap filed material. A plurality of slots in the back wall and front box trim bead hold removable dividers in the pans. Splicing members permit several file column sections to be mounted vertically upon one another forming a power file several stories high which can be shipped in knockeddown form and assembled at the installation site.
