when the trap-doors are closed and the openings 19 in the digesters are also closed tight, so that there can be little or'no escape of steam. Steam is then turned on by the pipes 25 and 28 until the entire mass has been permeated and cooked, which usually occupies forty-five to sixty minutes, according to the steam-pressure. When the cooking process has been completed, the pressure is shut off from the port 28 and extra pressure is increased through the port 25. all moisture downward through the mass and through the bottom 21, from where it is driven oflf through the pipe 80 into condensing-t anks to cool, when the oilwill be released from the gelatin and water and may be drawn oil? into tanks arranged for its reception. After this the water is evaporated from the gelatin by heat, and the oil and the gelatin may then be refined and placed in con venient marketable form. After allmoisture has been ejected from the mass in the digesters, as before mentioned, the doors 24 are opened and the residue is then taken from the digesters, when two steam-pipesconneeted with said digester and passing into the same, and the outlets thereof being located respectively above and below said foraminous plate; and a steampressure-operated devicelocated to close one of said steam-pipes, substantially as specified. 2.

4. In an apparatus for the purpose described, the combination of a cylindrical digester having conoidal ends and provided between the same with a discharge-opening, a perforated bottom, a safety-vent 27 at the upper apex of the digester, and a dischargepipe at the lower apex of the same, substantially as described.
