CASWELL'S PRESS. 



Among the many contrivances, for obtaining great pressure, we 

 find a very simple one, invented by Lebbeus Caswell, of Harri-

B, a large cog-wheel, which is turned by the screw. 



C, a smaller cog-wheel on the same axis with B. This plays 

 into the cogs which are on the semi-circle D, and which is attached 

 to the lever E. 



F, is the fulcrum of the lever. 



G, a platform which may be moved to different parts of the lever.

nearer the fulcrum, the less distance does the lever move. Still if 

 may be modified so as to regulate this, and it will undoubtedly be 

 very useful for many purposes, — such as pressing cheese, cider, &c. 



INTERNAL IMPROVEMENT. 



Expeditious mode of conveying Kews, proposed.

 are among the contrivances in most general use for despatchirif^ 

 information. In turning over the leaves of a little work, calleri
