Filter Press: Iron Plates and Frames Clamped by a Jack-Screw (Spencer, 1917)
The sugar-house filter press: a row of iron plates and frames, each covered with filter cloth, hung on a heavy framework and squeezed together by a strong jack-screw. The cloth itself seals the joints. Mud pumped in collects as cake in the frames, and the clear liquid runs out through cocks on the plates.
Result: a plate-and-frame filter press that works best at about 40 lb per square inch.

Make the plates and frames
Make the plates and frames
Make the plates and frames of iron, with outlet openings and cocks on the plates for the filtered liquid. For a frame (side-feed) press, cast a lug on each frame and plate with an opening, so the lugs line up into a mud channel. For a centre-feed press, make heavy recessed plates with a round opening in each instead. Ours: iron castings. Not given: sizes, the number of chambers.

Build the frame and jack-screw
Build the frame and jack-screw
Build a heavy framework that carries the plates and frames in a row, with a powerful jack-screw at one end to clamp them together. Not given: the framework's sizes and metal.

Dress it with cloth
Dress it with cloth
Hang a heavy cotton filter cloth over each plate, with a thin cotton cloth over it to protect it from wear; the cloth makes the joints between plates and frames. In a frame press the cloth has no hole, and rubber rings or cloth 'stockings' seal between the lugs. In a centre-feed press, cut a hole in the cloth to match each plate's opening and clamp the cloth to the plate there. Screw the pack tight.

Steam it and press
Steam it and press
Before use, blow steam through the press until it comes freely from the cocks. Pump the mud in: about 40 lb per square inch gives very good work, and juice is pumped in at up to about 45 lb. More pressure risks breaking the press and blinding the cloths. The solids collect in the frames and the clear liquid runs off at the cocks. To wash the cake, close the cocks on the water plates and force water through it. Ours: a diaphragm pump.
