Abstract
An oil filter crushing apparatus has a crushing frame (12, 312) mounting a filter platform (16, 316) on which a used oil filter is supported on end for crushing by a ram device (40, 336) having a single ram rod (52, 338). An air spring actuating device (42, 344) is mounted on the frame (12, 312) and operates on low pressure shop air for selectively forcing the ram device (40, 336) downwardly to crush the filter against the platform (16, 316).
