  • Patent number: 3944210
    Abstract: Apparatus for counting and endorsing documents and more particularly tickets dimensionally within the preferred range from 1 inch by 2 inches to 2 inches by 5.5 inches and in the thickness range from two mils to 14 mils. The stack of tickets is placed in an in-feed hopper and is engaged by an eccentric bottom feed picker to drive preferably the bottom-most document toward a drive wheel and stripper wheel assembly to permit documents to pass only in single file beyond the stripper device. The documents are fed in single file between cooperating belts until they are picked up by acceleration means which abruptly accelerates the documents to provide a gap therebetween suitable for counting purposes.The documents are driven into a stacker wherein they are stacked in the same order in which they were loaded into the in-feed hopper. A stacker arm provides pressure on the building stack which pressure is continually reduced as the stack increases in height to assure a smooth stacking operation.
