Abstract

Workpieces are advanced using a series of hydraulically operated jacks disposed in a regular series below a channel in the sole plate of pref. a progressive heating oven. The jacks periodically raise the work pieces to be independent of the oven housing which is then hydraulically moved forward, the vertical jacks replace the work pieces and the oven is returned to its origin. The pieces are thus cyclically advanced through the oven by a device which may be fully automated and inexpensive in construction.
