On page 5G, Vol. XII, of the SCIENTIFIC AMERICAN, we illustrated and described an improved cotton press invented by J. A. Dis-brow, of Poughkeepsie, N. Y., and to that page we must refer the reader who wishes to obtain an intimate knowledge of the interior construction of the one now under consideration, as in that respect they are similar. It may be well to state that the follower is drawn down by ropes, which in some measure relieve the sides of the box from the great pressure of the cotton or hay on the sides. The invention in the present modification is in the mode of operating the drums on which the ropes are wound, and this will be seen from the accompanying engraving and description. A is the box, being secured at the top, B, and having two doors, D, for the admission of the material to be pressed ; when full, these are kept quite close by bars, E, fitting into catches, F. G is the base, provided with a small guide wheel, H, which steadies the press on the circular cog wheel, I, by moving in a smooth way, N. The press can be moved round this circle on a pivot in its center, by the lever, L. When the press is moved round, the large wheel, J, is rotated, and with it the small one, M, on its shaft. This gears into K, the shaft of which also carries the drum that winds up the rope and draws down the follower, so that by moving E the press is operated. It is a convenient press, and was patented by the inventer February 2, 1858, by addressing whom, orR. L. Allen, 189 and 191 Water street, New York, more information can be obtained
