ABSTRACT:

BACKGROUND OF THE INVENTION
This invention relates generally to loading systems used for loading a fluid-like substance, such as crushed coal or other particulate material or liquids, into transport receptacles, such as intermediary dumper cars designed to load railroad cars, and more particularly, is concerned with such systems which are capable of loading transport receptacles while such receptacles are either stationary or in motion.
To enhance the flexibility and speed of a loading operation utilizing a fixed load point, it would be desirable to provide means for such a loading system which is capable of being interposed between the fixed load point and transport receptacles to be loaded for providing a moving load point.
Accordingly, it is an object of the present invention to provide new and improved means for transferring a fluid-like substance from a fixed load point to a transport receptacle.
Another object of the present invention is to provide such a means which is uncomplicated in construction yet effective in operation.
SUMMARY OF THE INVENTION
This invention resides in a material transfer system for transferring a material from a source to an open-topped receptacle wherein the material is capable of gravitationally flowing from a source.
The transfer system includes an open-topped dumper having an interior, an outer periphery which is substantially circular in form as the open top of the dumper is viewed downwardly theretoward so that the dumper is provided with a vertical center axis, and divider means for separating the interior of the dumper into open-topped compartments. Each compartment has a discharge port through which the contents of the compartment can be discharged.
The system further includes means for supporting the dumper for rotation about the vertical center axis of the dumper and means for rotating the dumper about the vertical center axis so that on one side of the vertical center axis of the dumper, the open tops of the compartments are movable into and out of vertical registry with material flowing therein from a source and so that on the opposite side of the vertical center axis of the dumper, the ports of the compartments are movable into and out of vertical registry with an open-topped receptacle to be filled from the dumper. Also associated with the dumper are means for selectively opening and closing the ports of the compartments so that discharge of material from each compartment is prevented when its port is not positioned in vertical registry with an open-topped receptacle to be filled from the dumper and so that discharge of material from each compartment is permitted when its port is positioned in vertical registry with an open-topped receptacle to be filled from the dumper.
