Next, a stainless- steel press with a screw-driven plunger was constructed (fig, 3).

 with end plate removed: (A) Chamber; (B) funnel for adding diet; (C) copper 

 tube; (D) large copper tube containing 15 smaller copper tubes; (E) center 

 of large copper tube: (F) pipe used for axle and circulation of water inside 

 chamber; (G) end plates. 



The press, with a chamber (A) having a capacity of 2,500 ml. , was built with a 

 funnel (B) so that the melted diet could be poured directly into the chamber and then 

 forced out through a 5- inch pipe fitting (C) in the end plate (G). One end of a 25-foot 

 length of 5- inch copper tubing was fastened to the pipe fitting, coiled, and immersed in 

 a tank of cold water. It was hoped that the hot medium could be forced through the 

 tubing, cooled by the water, and be extruded as a continuous cylindrical rod of diet. 

 The continuous moving of the medium as it cooled in the tube caused the partially 

 solidified mass to crumple and emerge from the tube as a paste. 



A revolving cooling device (fig. 3) was then constructed, for which a large copper 

 tube (D) 3 inches in diameter and 18 inches long served as the chamber. Two end plates 

 were fastened to the chamber and 15 smaller copper tubes one- fourth inch in diameter 

 were each inserted through the end plates of the large copper tube so that they were all 

 equidistant from its center (E). The resultant chamber resembled the barrels of a 

 Gatling gun. A pipe one-half inch in diameter and 22 inches long (F) was run through 

 the center of each end plate to act as an axle and also to permit cold water to be 

 circulated inside the chamber and around the 5- inch copper tubes.
