ABSTRACT:
There is disclosed an article treating apparatus particularly apparatus for pressure-impregnating or vacuum impregnating porous articles such as metal castings. A holder for the articles or a metal basket containing them is disposed in an autoclave and can be rotated about a horizontal axis. It has a horizontal through-passageway so that articles to be treated can be simultaneously loaded at one end of the passageway and unloaded at the other end of the passageway by an indexing mechanism. The indexing mechanism has a plurality of pusher arms which can be moved laterally into the path of the articles and then moved horizontally to push the articles along rails into and out of the passageway. The holder is stopped at a predetermined rotary position in which a longitudinal slot is opposite the pusher arms so that unloading and loading may be effected simultaneously with a single movement of the indexing mechanism, a pusher arm passing completely through the slot. The lower part of the pressure vessel contains liquid impregnant and the holder can be rocked between an upper loading and unloading (and spin) position and a lower immersed position.
