This press can be operated by any convenient power, and is intended to compress the cotton both laterally and vertically by the same application of power. This end is attained by having one side of the press-box made movable, and arranged so that it may slide. This is done by means of toggles and slides, as will be seen by a reference to the illustrations, of which Fig. 1 is a perspective view of the press. Fig. 2 a side view of the connecting links, and Fig. 3 a vertical section of the press. Similar letters refer to the same parts in each. A represents a suitable framing, in which a press-box, B, is secured, and C is a screw which passes vertically through the cross-tjes, a and b, in the upper p%rt of the framing ; D is a nut fitted on the screw, C, between a and 6, and provided with two bevel wheels, c and d, the upper wheel, c, being much larger than the lower one, d. Small friction rollers are interposed between the top of D and a, to lessen the friction when the press is in operation. F is a horizontal shaft placed in the upper portion of the framing, and having a driving wheel, g, on its outer end ; the inner part of this shaft has its bearings in a lever, h, by which it may be raised or lowered, and, by means of pinions, i and j upon it can be thrown in gear with either the upper or lower wheel of the nut, D. To the lower end of the screw, c, is attached a follower, E. The side of the press-box, h, is made movable or allowed to slide laterally in either direction indicated by the arrows 1 and 2, (Fig. 2,) this side having horizontal bars, / /, attached to it, one at its upper, the other at its lower end. To each of the bars, I I, there is attached a metal bar, m w, these bars rest on guides or cross-pieces in the framing, and to the front part of each bar, m, one lever, n, of a toggle is pivoted, the other levers, o, of the toggle being pivoted to the framing as seen at . There are toggles at each end of the press-box connected by a vertical bar, G. To each of these bars, G, a curved bar, I, is pivoted near its lower end, and these bars, I, have projections, j and r, upon them, the projections, y, being much longer than r, and their distance apart is equal to the thickness of the follower, E, as seen in Fig. 3. The operation is as follows : —Suppose the follower, E, to be in an elevated state, the cotton is placed in the box, B, and motion is given the nut, D, by turning the pinion, i, in gear with the wheel, c, the projections on I project underneath the ends of E, the nut D is now rotated in the direction of the arrow, 3, (Fig. 3) and the screw C and follower descend, pressing or forcing down the bars, G, which actuate the toggles and cause the side, h, of the press-box to be moved inward. As the bars, I I, descend, they are gradually forced outward, in consequence of springs, a', that are attached to their inner sides, leaning against the ends of the press-box ; and by the time the toggles are -fully extended and the side, K, forced in the requisite distance, the bars, 11, are forced outward so far that the proj ections are bey ond the ends of the followers. The follower then acts on the cotton, pressing it vertically, and when the cotton is sufficiently compressed in this direction, the bale is bound as usual, and the motion of D reversed, so that the follower, E, may ascend; and on its rising, it catches against the projec- tions, 7, which always extend over the edges or ends of the follower. The bars, 11, therefore, rise with the follower, and the side, IC, is moved outwards by the toggles as indicated by arrow 1, in Fig. 2. The projections fall under the follower when it has reached Its proper hight, and the press is again ready for operation. This press is remarkably compact and strong, and bj- first exerting the pressure on the sides of the bale, gives a more close one than when the pressure of the follower alone is employed. It is the invention of F. Vf. Witting, of Twelve-mile, Colette Gin, Texas, and any further information may be obtained by addressing him, care of C. Eckhardt, York-town, Texas. A patent was obtained for this press last week, as will be seen by referring to our List of Claims on another page.
