118 Account of a new Pummice Press. 



is laid a lattice bottom, which is supported by three ribs 

 of one inch and quarter wide, and half an inch thick. 

 Upon this lattice, an hair cloth or coarse bagging should 

 be spread, and it will be best to spread the same cloth 

 on three sides of the cribb, by which means the must 

 will run off quite fine. One side of the cribb is of 

 plank, and pressed against the uprights by the floor, 

 which is wedged on, by double wedges; and the other 

 three sides are tenoned into the plank side, with headed 

 pins, long enough to be readily knocked out when the 

 pummice is sufficiently pressed. That side of the cribb 

 is then to be turned outward, the pummice thrown out, 

 and the cribb returned to its place and refilled. The 

 side planks are tenoned together, and dove tailed up- 

 wards, at the outer end, and downwards at the foot of 

 the uprights. 



The whole space occupied by the press is 13 feet 7 

 inches. The frame of the cribb is pinned together, so 

 as to be very readily taken apart, into the three sides. 

 The whole press can be taken apart in about 20 minutes, 

 and put together again in less than an hour : and the 

 whole so taken apart, can be laid in a box 20 inches 

 square, and 8 feet in length. 



In my press the side planks are 10 inches apart, and 

 bottomed to receive the juice, which is to be drawn off 

 near the second lever. 



The side plank lying on the out side of the uprights, 

 is seven feet four inches long, from out to out. 



When only one pair of levers are used, as shewn in the 

 cut, the space for the other pair, between the uprights, 

 is occupied by a square block through which the pin at 

 A, passes, which keeps this le^•er steadily in its place.
