Oil Expressing Box.

Patent for a new and improved oil-expressing box. In this design, "the follower is adapted to fit the box, so as to obviate the need of any joint-closing device, and the face of the follower at its side edges is raised to better confine the bag in place, and at its center or central portion is channeled and provided with a false bottom to provide for the escape of the oil" (lines 24-31)
