Inventors:

Robert L. Elder - Columbus MS, US

International Classification:

A45F 5/00

US Classification:

294157, 294152

Abstract:

This device provides a simple,adaptable, reusible means of gripping a variety of bags, that is, bags of variable materials,variable contents, variable sizes, and variable weights; and may be used by two persons for lifting a single bagIt is comprised of two handles with a rope threaded through the two handles to form a closed loop. It works by positioning the loop around a bag lieing flat with the handles at the bag end, pulling the rope under the corners of the bag, and lifting the handles.The lifting force positions the rope under the bag,thereby providing the lifter a substantial and convienient method of gripping the bag.

Abstract:

A system for loading coal (particles) into railroad cars 16 wherein a control weight of a railroad car 16 loaded with coal (particles) is established and a maximum permissible weight of a railroad car 16 loaded with coal (particles) is known, the control weight being less than the maximum permissible weight, The system utilizes a continuous loading system 12 and a batch loading system 14. Coal (particles) first is loaded into each of the railroad cars 16 utilizing the continuous loading system 12 and the continuous loading system 12 is designed such that the continuous loading system 12 loads an amount of coal (particles) into each of the railroad cars 16 having a weight less than the predetermined control weight. After coal (particles) intially has been loaded into each of the railroad cars 16 by the continuous loading system 12, then coal (particles) is loaded into each of the railroad cars 16 utilizing the batch loading system 14 and the batch loading system 14 is operated to discharge an amount of coal (particles) into each of the railroad cars 16 equal to the difference between the control weight and the partially loaded weight of the railroad cars 16 after initially being filled utilizing the continuous loading system 12.
