to say that tho inner ends of the levers J K are secured to it, the one above the other. 

 These levers are connected by rods N at their outer ends, and these have pivot-joints passing 

 tin .mgh tho levers. L M are other levers securod by pivots to J K, and to lugs by like joints 

 in the po^ts. There is a pulley attached to each side of the follower lever K; below the ends 

 of the connecting arms is a large roller 0. A rope R is secured at one end on the bottom of 

 the frame, then passes over the outside pulley at N, then down around the roller 0, then up 

 and over the nigh pulley N, then down and around the pulley on the bottom of the frame. 

 By pulling on this rope, by winding it upon a windlass, &c, the upper ends of the levers J K 

 are drawn down, and the follower thrust forward, pressing the hay, cotton, or other material 

 with great force. Tho levers have a quick motion and exert little power when they first 

 commence to act, but have a slow motion and exert the greatest power near the end of the 

 stroke; this is tho kind of motion required. The action of these levers is parallel, like that 

 of the joints of a parallel ruler. 



The ropo P is connected at one end to the follower, then passes over a pulley on the top- 

 scantling of the frame, and down over another pulley. This cord is for drawing back the 

 follower and olevating the levers, when the cotton or hay is pressed and secured in bale. 

 This press may have a door on one or both sides. The foregoing engraving represents a bale 

 in tho press, bound ready for removal from the door C, there being another such door on the 

 other side, so that the bale can be removed from either side of the press at pleasure. B B
