the cistern, which can be lined 



with rollers on the two sides A

the washers, beaters or rollers are hung ; o o, represent a beater, &ic. 



attached to its rod F or/. This machine is operated by the upward 



and downward motion of the handle H, and can be variously modified. 



5. Application to Fvlling. 



Fig. 3 will serve to illustrate its application to a fulling mill or ma- 

 chine. There are two constructions to this application ; a vertical 

 and horizontal. Fig. 3 enlarged, _ f^'g- 4. 



will represent the vertical one. 

 The horizontal one is nearly the 

 same as the vertical, only that the 

 lever and rods have a horizontal 

 motion, and the cistern must be 

 modified a little to answer it. In 

 both constructions, the operating 

 power is to be applied to the han- 

 dle H. 



6. Application to an Aerostatic or 

 Hydrostatic Press. 

 Fig. 4 represents an aerostatic 

 or air, or a hydrostatic or water 

 press AB CD, its frame j ^-Tthe 

 airor water cistern, which in shape 

 resembles the segment of a hollow 

 sphere or hemisphere; T a strong 

 hollow cylinder inserted in, or at-" 

 tached to the bottom of the cistern; JVn the follower, a strong bar, 

 fitted to move up and down in the sides D Z? of the frame. To this
