Improved Cotton Press

1872 Scientific American  
In this eotton press, the follower is moved from bottom apwards, forcing the cotton into the upper part of the ma chine, by the action of hand power applilild through the in genious combination of mechanical devices below described. The engraving shows a perspective view of the apparatus with the follower at its lowest position. A is the press case. Hinged thereto on either �ide, and opening from the top eownward, are two doors, B, one of which is represented as open and raised, and the other
more » ... ed, and the other as shut. A cover, D, closes the top of the press case. This opens upward on the pivots, E, and is moved by the hand levers, F F. When ahut it is firmly fastened by the bar, G, the extrem ities of which are held in the metal links, H, at tached to the beams, I. J is the follower, con .tructed as shown, attached to which, on either lide of the press, are the notched bars, K, which are confined in suitable iuides, L L. The cotton being placed in position, the lower doors, B, and the cover, D, closed, the bars and, at the same time, the follower, are raised by means of the lev ere, M. These are pivoted to supports, N, and to their short arms are attached links, 0, which, pase ing over the bars,. engage in th8ir notches, thus lifting them, when the outer ends of the levers are forced down. P shows one of the holding pawls, which retain the bars when the links go back to engage a lower notch after lifting the bars to the hight of their range. Also attached to each end of the follower are ropes, Q, which, passing over pulley, R, on the supports, N, serve to lower
