&c, 'like two combs, one fastened on each side, the teeth of 



one going into the interstices of the other, so that it may 



effectually prevent the book falling too low, whether the 



press is open little or much. 



In the common press, the book is put in the middle, 

 and there is a screw at each end to force the press to- 

 gether ; but in this press, the book being put at one end, 

 there is a screw about tlie middle to force the press toge- 

 ther, and another screw at the lower end to force it 

 open, and consequently press the book tighter, exactly 

 on the principles of cabinet-makers' hand-screws.
