ABSTRACT:
Apparatus for transporting a sheet of glass in a vertical position where the apparatus has self-tightening tongs adapted to clasp an upper portion of the sheet. The tongs are operatively connected to a strap having a toothed support face. A beam supported by a trolley has a toothed support face thereon where the spaces between the teeth differ from the teeth of the strap. A differential block having a plurality of teeth on its upper side corresponding in shape and pitch to the teeth of the strap and having a plurality of teeth on its lower side corresponding in shape and pitch to the teeth of the beam is inserted between the support face of the beam and the strap to provide an adjustable connection between the beam and strap.
