Patent number: 4674627Abstract: An easily-cleaned, rubberized conveyor assembly especially adapted for conveying granular or semi-fluid material. The present invention is particularly concerned with conveying food materials where cleaning and sanitary conditions are important. The invention is also particularly described with regard to a conveyor for the bottom of a holding or surge bin, but has other applications. In the invention, upright side guards along opposite sides of a continuous rubberized belt separate the belt into a central load-carrying portion and outer edge aligned portions. Connections connect the edge aligned portions to supporting girts beneath the belt, the girts in turn being attached to endless conveyor chains on opposite sides of the belt. Preferably, the side guards are rubberized elements vulcanized to the belt surface, thereby providing an assembly having a load-carrying area free of cracks or crevices.Type: GrantFiled: November 8, 1984Date of Patent: June 23, 1987Assignee: Proctor & Schwartz, Inc.Inventor: Dussan V. Benlcio I.

Patent number: 4619576Abstract: A feed system for feeding light-weight materials, such as tobacco, into large blending and/or bulking bins. The present invention resides primarily in a novel, light-weight feed system comprising a trolley and a shuttle conveyor adapted to reciprocatingly feed rapidly in either a longitudinal or lateral direction with a minimum amount of inertia during acceleration and deacceleration. A feed conveyor deposits said material onto the shuttle conveyor, said feed conveyor comprising drive elements adapted to synchronize movement of the feed conveyor with movement of the shuttle conveyor. The shuttle conveyor, at least in the X direction, is unencumbered mechanically by the feed conveyor.Type: GrantFiled: August 28, 1985Date of Patent: October 28, 1986Assignee: Proctor & Schwartz Inc.Inventors: Kurudamannil A.
