134 FEEDING WITH SUGAR BEETS, SUGAR, ETC. 



ment forces the cossettes from the upper broken spiral into the 

 lower continuous spiral. The motion is given by the pulley, 

 a', on whose axis a pinion, 6, works into a large cog-wheel, b f . 

 On the horizontal axis, K, two pinions of different sizes are 

 placed opposite to each other, the smaller of which, c, gearing 

 into the bevel wheel, c', on the axis of the inner cone, and the 

 larger pinion, d, gearing into d ', on the axis of the outer cone. 

 It is plain, therefore, that the cones will revolve in opposite 

 directions. The cones are slit in many places, as shown on the 

 broken portion of B. These are covered with finely perforated 

 tin, so that the sweet water may run off easily and at the same 

 time be freed from cossettes. 



There is a man-hole at the bottom of B to afford access to the 

 interior, and around the man-hole is a rim to prevent overflow 

 of the expressed water. C is. a hopper, and Hi are three iron 

 bands on the outside of cylinder, Z), to strengthen it at the 

 point of greatest pressure. There is an outer casing, ", whence 

 the liquid flows through GG into H. From the inner 

 cylinder the sweet water flows into some exit through the 

 hollow axis, which rests in the hollow step, F. The cost of 

 this press is greater than the Klusemann apparatus. During 

 recent years another press of the Bergreen model has come into 

 existence, an engraving of which is shown herewith. The 

 outer portion, A, of the old model is done away with. This 

 apparatus is cheaper and works very satisfactorily. 



Lallouette Another mode which for a time had some popularity, is the 

 press. Lallouette press, shown in Fig. 9, which is not without interest 

 as it has been used subsequently to the standard Klusemann 

 and other presses. The filling may be done with a pulp-pump,* 

 and 15 tons of pulp may be pressed in twenty-four hours. In 

 France this press was not only used for the refuse beet pulp, but 

 also for first and second pressing of the rasped beets. Mr. 

 Lallouette' s idea was to diminish the water in excess in the 

 diffusion pulp, so that the latter would contain no more of it 

 than the pressed diffusion cossettes. His experiments consisted 



* The pulp-pump is of curious construction. The valves must be necessarily 

 made large, not only to permit the passage of the liquid, but also of substances 

 in suspension.
