in the mechanic arts, a machine of wood or iron, serving to squeeze any body very close, generally by means of a screw.

Presses usually consist of six pieces; two flat smooth planks, between which the things to be pressed are laid; two screws or worms fastened to the lower plank, and passing through two holes in the upper; and two nuts in form of an S, that serve to drive the upper plank, which is moveable, against the lower which is fixed.

Presses used for expressing liquors are in most respects the same with the common press, only the under plank is perforated with a great number of holes for the juice to run through. Others have only one screw or arbor, passing through the middle of the moveable plank, which descends into a kind of square box, full of holes, through which the juices flow as the arbor is turned.
