Abstract: An apparatus for conveying solids from a lower to a higher elevation, such as metal cuttings from machine coolants, including a horizontal auger rotatably mounted in the semi-circular bottom of an open top hopper, one end of the hopper being open, an inclined auger rotatably mounted in a semi-circular bottomed inclined housing, the lower end of the housing communicating with the open end of the hopper, and the lower end of the inclined auger being below the hopper, the housing having a discharge chute at the upper end, liquids and solids inter-mixed being deposited into the opened top of the hopper to permit the liquids to overflow the hopper while the rotating horizontal auger moves solids onto the inclined auger which moves the solids upwardly within the housing, allowing the liquid to be drained therefrom and back into the hopper, the solids being discharged out the outlet chute and the liquids permitted to be returned for reuse or disposal.

Abstract: An apparatus for separating solids, such as metal cuttings, from liquids, such as machine coolant, the apparatus having an upwardly inclined elongated housing which in cross-section is U-shaped with a semi-circular bottom and parallel sides, the housing being opened at the top and covered throughout its length by a removable lid, a helix rotated in the housing and extending from the lower end to the upper end, the housing having a solids discharge chute near the upper end, a gear motor mounted on the upper end of the housing for rotation of the helix and having at the lower end an upwardly extending fluid inlet chamber, the open top serving as an inlet by which solids containing liquids is conducted into the apparatus and having an upwardly extending overflow chamber connected with the lower portion of the housing, the walls of the overflow chamber being of less height than the inlet chamber, the inlet chamber, the overflow chamber and the lower portion of the housing together forming a quiescent zone in whic
