Abstract
Abstract A vertically and horizontally displaceable coal outlet guide is shiftable in respect to the lower tubular discharge of a coke furnace charging truck. The lower coal outlet guide is of frustoconical construction and it includes an upper top cover plate which may be adjustably positioned in respect to a lower plate for the purpose of orienting the opening in the upper portion of the guide with the discharge tube at the lower end of a conical charging truck. The lower guiding portion is supported on pivotal arms and it is confined for vertical guiding movement by guide bars which are guided in sleeve members carried on each side of the charging truck. The lower coal guide extension is shiftable upwardly and downwardly by a fluid-operated piston and cylinder combination which is mounted on the truck and connected to the lower portion through a pivotal lever member.
