Abstract: The double hydrostatic oil press as constructed by us operates upon the seed, or other substance to be pressed, by means of two pistons which are forced out of the opposite ends of a cylinder placed horizontally, which two pistons are subjected simultaneously to the power produced by the ordinary hydrostatic press, or any forcing pump operating upon the same principle. Claim: The employment of two pistons operated upon in the manner, and for the purposes herein set forth for pressing oil from seeds, and for pressing other articles to which the same may be adapted by means of hydrostatic pressure, by which means the labor of so doing is lessened, not because any increase of power is obtained, but because two charges are pressed at the same time, and the charging with water, and also the discharging has to be less frequently performed.
