disks is the greatest, and at a the least, the cossettes reach a con- 

 tracted wedge-shaped chamber whose walls continually move 

 towards the smallest space, and are carried around by the fric- 

 tion and rotation of the disks. As the latter gradually approach 

 the narrowest portion of the space a, the narrowing disks exert 

 a most powerful pressure on the cossettes, while the liquid con- 

 tained in the latter passes through the perforated surfaces of the 

 pressing disks. The pressed cossettes, passing the narrowest 

 portion a after which the distance between the disk-surfaces 

 again widens are forced by the following mass against the fast 

 scraper F out through the opening M in the jacket, and form a 

 tolerably consistent mass. The pressed-out water flows through 

 larger openings in the jacket, into a drain H. 



The degree of pressure on the cossette, which is in proportion 

 to the distances between the disk-surfaces a,, a, can be altered 

 by altering the press disks A, A t , 

 which can be moved on the axis 

 C C, by set-screws provided for 

 that purpose. 



The cone cossette press can be 

 placed either on the surface of the 

 ground, or over chambers which 

 can be used for other purposes, 

 provided the liquid can be carried 

 off properly, since the machine 

 has no separated parts, and the 

 pressed cossettes fall from it at 

 the height of one metre, so that a 

 transporter can be run under to be 

 filled, and carry the cossettes to 

 another place. 



In most cases it would be best, 

 especially if Klusemann's press is 

 to be run with it, to arrange this 

 press directly under the cossette 

 elevator, in the story over the 

 cossette storage room, as shown in 



the accompanying small cut. When there is sufficient height
