to open, and to release the blank, \vliich falls upon the face of the lower die. The 

 opening of the finger, or hand, is effected by a pin which works in a slit in the moveable 

 finger of L. The continuation of the motion which draws back L, causes the rods E, 

 which are carried by the main screw D, to release the collar by the levers o. The 

 collar being thus relieved from downward pressure, rises by the elasticity of the 

 springs until it wholly encloses the blank which has been left on the lower die. The 

 rods E pass through the shoulder of the frame of the press, and are destined for

another service besides that just described ; for the main screw D, which travels 

 through a female-screw fixed in the frame of the press, thereby receives its power to 

 rise or fall upon each part of a revolution, whereas the upper die must strike the 

 blank a blow just such as would be struck by a hammer, and without a twisting 

 motion ; therefore that motion of D is lost just below the lower D, where D fits into a 

 cup suspended rigidly on, and is preventud frum twisting by, the rods i, as shown at r.
