APPARATUS FOR TRANSFERRRING FLOWABLE MATERIALS FROM A FIRST VESSEL INTO A SECOND VESSEL ABSTRACT OF THE DISCLOSURE Apparatus for transferring pulverulent or granular material from an opening at the lower end of a silo into a vessel which is moved to a position below such opening has a vertical duct with a rigid upper section which is affixed to the silo, a rigid lower section which is surrounded by and is rigidly connected to a downwardly tapering funnel and serves to discharge flowable material into the vessel by way of an opening in the top wall of the vessel, and a bellows which is disposed between and is separably connected with the two rigid sections. The lower section and the funnel are movable up and down by means of a winch and several cables or chains whose lower end portions are attached to the funnel and/or to the lower section. A cover which normally overlies the open upper side of the funnel is movable to a raised position in which it surrounds the upper section of the duct. This provides room for insertion of an outer bellows whose lower end portion is sealingly connectable with the upper end portion of the funnel and whose upper end portion is connectable with the marginal portion of the cover. Air which is expelled from the vessel flows between the funnel and the lower section of the duct in the lower position of the cover; such air escapes by way of a pipe on the cover. When the cover is raised and the outer bellows surrounds the bellows of the duct, the compartment admits air into the annular space between the two bellows, and the air again escapes by way of the aforementioned pipe on the cover. - 2 -
