Abstract
A device for loading granular material containing some foreign matter into a container, such as a railroad car, has upper and lower chutes arranged in parallel. The upper chute has a bottom screen for allowing the foreign matter to fall through to the lower chute. The grain flow remaining on the upper chute is discharged down the center of the car and fills toward the sides, while the foreign matter falling to the lower chute is distributed evenly by sidewardly extending wings out toward the sides and in towards the center of the car. By the operation of the device, the foreign matter carried in the grain is evenly distributed and mixed throughout the car, and the tendency of the foreign matter to concentrate along the center under the hatchway of the car is prevented. A sample of the grain taken from the hatchway of the car thereby contains a truer percentage of foreign matter to grain than would occur by conventional loading devices.
