To all whom it may concern: A l

Be it known that I, WILLIAM'E. Srxsrrmno, of it. Joseph, in the county of Buchanam'and State of Missouri, have invented certain'new and useful Improvementsv in Hayand Cotton-Presses; and I do hereby declare the following to be a fulliclear,` and exact description thereof, reference bein`ghad to the Accompanying drawings of the same, making partof this speciication, and in which- Figure lrepreseuts a side elevation; of af press, embracingmy improvements;

Figure 2 represents a vertical section oil ythe same; Figure 3 represents a horizontal section of one side af the press; and i Figure 4 represents one of the gauge-slides, showing the scales by which the movements o ,theslides are graduated, and the scales for dete ming the weight oi' the bale. My improvements relate to that class o f;prcs'ses operated by hand, and consist inconneqtji gthe. .fo1-

lower to the operating-screws, by means of 'haiiis and intermediate nuts, in connection 'with'auxiliarynts,' ner. .that

in either end of the followerin suoli a apap the power of the screw will be applied to thez'ioilhwcr by means oi' chains and intermediate nuts only at the commencement of the pressing, and subsequently through the direct connection of the lfoll x\ vex 'by means of the auxiliary nuts with the screws, thereby obtaining a double connection with said screwsfor the purpose of 'increasing the power in proportion to the increased resistance of the article being pressed, thereby relieving the screws of the danger of breaking their threads, to which they arc always liable with a single connection with the follower.

My improvement also relates to the arrawfement of gauging-slides, supported and operated by tht'cllower. for the purpose of ibrming the sides of theease, and regulating, during the operation of pressing, the position of the follower, keeping it equal-at bhth ends, and. thereby prevent the binding ofthe fp lower-by reason of its assuming an inclined position v within the press, while heilig raised or lowered. l;

My improvement also consists in providing the-'slides with scales of numerals, arranged in connection ,with the 4scale of inches,for the pprposc oi'mcertalning and determining the weight of the bale, x 'rdiug to the degree of impression given to it bylf he press, whereby the press is made to indica-te, arri-,oni tically, the exact weight of the bale while linden".preislnc1 In the accompanying drawingss .7

The flame A ism-ade in the form oi' an iprightoblong box, supported b v sills B, and constructed 4in a substantial manner. Within this box, tlieffollower C is placed, and at thc top, thc head-block; Ltshingcd and secured by rings E, fitting over the projecting ends F, of the headblock, in the usual manner. The press is alsoprovided with side-doors G, hinged so as to drop down out of the way while strapping the bale, and secured, when closed, by cross-bars H, fitting into staples on the doors and the flame, in the usual manner.

At the opposite sides of the press, l arrange a vertical screw-shaft, I, permanently connected to the upper part of the flame, and supported by a collar, J. These screw-shafts I, do not extend to the bottom of the frame, but Aare united to the follower on either'side, by lmeans of two chains, L L, and an intermediate nut, M, so that when the follower is down, it issuspended and supported by the chains alone, as shown intig. 1. The opposite ends of the follower project through openings N, in the sides of the box, and the chains L L, by whichthe follower is suspended, are placed on either side of, and parallel to the screw-shaft, and'unite the followerto the intermediate nut M, which is prevented fromtuming with the'screw I by. contact with the side of the slides Q.

This connection of thc followerl with the screw, by means of the chains, is sutlicient to produce the vrcquired degree of power at the commencement ofthe operation of compressing a bale, but as the pressing advances, and the resistance of the bale increases, the strain upon the chains and the single connection ofthe intermediate nut` becomes very great, and endangers the breaking of the chains and the threads of the said nut. To prevent this, therefore, and to increase the power'of the screw in proportion to the increased resistance of the bale, I arrange an auxiliary nut, P, in each end of the follower, fitted with a female screw of a. diameter corresponding to that of the screw-shaft, so that the follower ascends by its connection with the -intermediate nut, until the force upon the screws is measurably increased, when they are caused to take into the auxiliary nuts of the follower, as shown in iig. 2. Thus, 'the lower nuts come to therc'lif of the upper ones, and constitute a double connection with the screw, thereby doubling the power of the screw, by equaliziug the force between the intermediate and auxiliary nuts. This method of increasing the power of the screw is of great importance, and permits the bale to'bc compressed with a' far greater degree of compactness than could be obtained by the single con` n ection of the followerwith the screw, as heretofore.

In hand-presses, where the follower is operated by screw-shafts, the former is liable to assume arr inclined position, and bind against the sides of the b'ox. To maintain the follower always parallel to the top of the press, I arrange a vertical-sliding gauge-board, Q,.on either side of the press, next to the screw-shafts, so

. are fitted into grooves a, fig. 3, in` the sides of thei turn the shaft, either to the right or left, to elevate or 'saving niucluy time, labor, and expense, in weighing the article after it is. pressed and baled, it being ready thattheir lower 4endsrest upon the opposite ends of the follower," at V, fig. 2. These gauge-boards are of a length nearly equal to the height of the press, and

press, so as to close the opening N, in which the ends of the Iillcvfer move, and forma part of' the inner casing the Lbpposite sides of the press, in such manner as t' 4rise and fall with the follower. These slides are prorlided with scales on their outer sides, so that the opblrators can observe, lalike from the opposite sidesinfl theV press, theexact degree of elevation or descent` `the slides, while .turning the screws, and ther-ebl aintain the follower in a horizontal position, and effect a free and perfect operation ofthe press.

The 'screws are provided, near their upper ends, with notched circular heads and `a. hand-lever, S, is also fitted tn eaclx ,screw-shaft, so as to ,embrace these notched; lxjea'da jin such manner that a' continuous spring-arm, T, secured to either side of thelever, will take iinto the notches of the circular head, and Athus depress the follower. A

Both sides' of the gauge-boards may be provided with scales, so that either operator-can see the scale of the opposite `gauge,.witl1out requiring the operators to gtell the divisions of the scales as the operation progresses, by which means they can always graduate the position of' the slides.

vlhese' gauging-scales also perform :mother impor. tant fanctioxgthatof determining the exact weight of the bagby suitable figures, indicating different weights at diisent degrees of compression. This feature adds greatlyto the utility of the gauging-slides, and constitutes n, automatic weighing-press, according to the degree'of.- compression the bale may receive, thereby forth,I rnarltet as delivered from the press. The gaugipg'mf' :the scales, to ascertain the weight, must be determined from the area of the press, according to they degree of compression of the bale, indicated by. 'the ,sca-le.

- AsI'OttQn, hay, and hops, would occupy a different area, ithe'isame degree of compression, there will be no difficult-yin determining the exact weight from the l BEST AVAlLABLE CQP subdivisions of the scales, and these several scalesI of' inches and numerals may be arranged to be read from the bottom or top ofthe slides, as convenience and facility may determine.

The scale of inches and feet is arranged 'so as to be read in connection with the scales of pounds and hun- Adred weight. The slides, therefore, serve three purposes, viz, movable slides to the openings Nain the press-easing; to maintain the follower in a horizontal position; and to indicate., automatically, the weight ot the bale, when pressed, whatever the degree of compression, or the character ofthe article being pressed.

The top of the fra me A constitutes the fixed guide, from which to read the scales, and to determine'the position of the follower.

Having described my impmvements,

I claim- 1. The combination and arrangement of the intermediate nuts M, the screw-shaft I; and the connectl ing-chains L, with the follower O, and auxiliary nuts P, substantially as before described.

2. Thecombination and arrangement of the gang ing-slides Q with the follower of a press, for the `pu!-- pose of ascertaining and regulating-the ascent and descent ofthe follower alike at both ends, substantially as before described. Y

3. The gauging-slides Q, arranged so as to-form the sides of' the opening N, in which the follower moves, while, at the same time, they are free to rise and fall with the follower, as before described.-

4. The means herein described and represented for#l determining, automatically, in a press, the weight of the bale, according to its degree of' compression, substantially as before described.

5., The gauging-boards Q, provided with sea-les, for determining both tbe degree of compression and the weight of the bale, according to any degree of' compression, as herein described.

In testimony whereof, I have hereunto signed my name. L
