IMPROVEMENT IN COTTON-PRESSES.

Specification forming part of Letters Patent No. 3,885, dated January 16, 1845.

To. all whom it may concern:

Be it known that I, PHILos B. TYLER, of New Orleans, of the State of Louisiana, have invented a new and Improved Press for Oompressing Cotton, Hay, and other Substances; and I do hereby' declare that the following is a full, clear, and exact description of theconstruction ofthe same, reference being had to the annexed drawings, making a part of this specication, in which- Figure 1 is a front elevation, and Fig. 2 an edge or side view.

The nature of my invention consists in applying power to the compression of cotton or other substances through the intervention of two sectors gearing into a double rack attached directly to the piston of a steam-cylinder, or connected with the piston-rod by connecting-chains, in a manner well known to all mechanics, and connected with the platen by the means of two bars or rods, said connecting-rods being attached to the sectors at a point within their circumference which, when they revolve by the action of the racks, raise the platen with a power increasing in the proportion, or nearly so, of the increased resistance of the material under pressure.

The drawings willfshow the manner in which I intend to construct my press for the compression of bales of cotton.

Let A be the cap of the frame; B, the bed; G, the platen; D D, columns; E E, the sectors;

'F F, the rods connecting the platen with the sectors G, the double rack gearing into the sectors and connected directly with the piston H; I, the steam-cylinder; J, the steam-chest, in which is the valve operating upon the proper steamways for lling and exhausting the cylinder.

It will be seen that, for obvious reasons, I employtwo sectors, one ofwhich-is connected to each end of the platen by means of the rods F F;

and, in order to determine the best position for connecting the platen with the sectors, it is necessary to ascertain by experiment the ratio of increase of the resistance as the compression advances. Vitli this view I have made a series of experiments with bales of cotton, and` have regulated the distance of the connectingrods from the center of the sectors according to the results of my experiments. In ,my press I attach the connecting-rods to the sectors two feet from their centers and about nine inches below the line drawn from the center of. one sector to the center of the other when the platen is at the lowest point, which will give an increase of the power of the press ,y

What I claim, and desire to secure by Letters Patent, is-

The arrangement of the sectors anddoublerack piston-rod, in combination with the folA lowerof the press by means of the connectingrods, to adapt the movement of the platen or follower to the increased resistancev of the cotton, and thus attain the greatest amount of effect with the least expenditure of power, as described.
