  • Glass accumulator
    Patent number: 4108319
    Abstract: A glass accumulator includes a first pair and a second pair of helically threaded rotating shafts angled away from each other. The first and second pair of shafts are rotated in opposite directions to vertically displace glass sheets from a horizontal conveyor and accumulate the glass sheets at the top of the shafts. Angling the pair of shafts away from each other minimizes contact between surfaces of the helical threads and the glass sheets.
