  • Patent number: 5393039
    Abstract: Similar to a paddle wheel, a rotary magazine for storing and conveying articles is mounted to turn about a horizontal axis and has radially extending vanes spaced around and fixed to the periphery of a central cylinder. At an accessible region an article is loaded axially into the space between an adjacent pair of vanes. It is kept from falling out by support from a cylindrical surface separate from the magazine and spaced slightly beyond the outermost tips of the vanes. The surface partially encircles the magazine from its lowermost region up to the level where the article will not fall out. A single ejector ejects in the axial direction each article in turn as rotation of the magazine carries it from the loading region to an ejection location.Optionally, an article can be treated, e.g. cooled, heated, irradiated, etc. in a treating chamber located on the path between loading region and ejection location.

  • Patent number: 4205717
    Abstract: A plurality of carriages, each containing a pouring ladle, are provided for pouring molten metal into moving molds of a conveyor. The carriages are essentially driven from a single motor and move in a closed loop containing a loading zone and a pouring zone. Each carriage contains a clutch pump to control movement along the loop. Rotation of ladles to a pour position is attained by use of a parallelogram linkage on the carriage and remotely located variable pour rate controls. A sensor system including an extension arm is supported by each carriage for sensing the presence of a mold car and for causing the carriage to match the speed of the mold.
