To all whom it 777/543./ concern:

Be it known that I, WILLIS W. KRUTSCH, residing at Little Rock, in the county of Pulaski and State of Arkansas, have invented 5 a new and usefull Cotton-Press, of which the following is a specification.

My invention relates to cotton-presses, and particularly to that class of presses which on account of their construction are known as 1o toggle-presses.

The objects of my invention are generally to improve presses of this class, to render them simpler, stronger, more durable, and easier and more effective in operation, and specially 15 to improve the construction of the various parts whereby such results may be attained; and with these objects in View my invention consists in the improved construction, arrangement, and combination of parts hereinzo after fully described and afterward specifically pointed out in the claims.

In order to enable others skilled in the a'rt to which myinvention most nearly appertains to make and use the same, I will nowproceed 25 to describev its construction and operation,

having reference to the accompanying drawings, forming part of this specification, in which- Y Figure 1 isa perspective View of a press 3o constructed in accordance with my invention in position for practical operation. Fig. 2 is a vertical longitudinal section through the same at another stage of the operation. Fig.

3 is a detail View of the crank detached from 3 5 the press, partly in section and partly in elevation. Fig. 4 is a detail perspective view of the crank detached. Fig. 5 is a detail perspective view of the outer portion of the crankshaft. Fig. 6 is a detail perspective view of 4o one of the toggle-levers. Fig. 7 is a detail perspective view of one ofthe toggle-lever bearing-plates. Fig. 8 is a detail'perspective view of one of the toggle-lever connecting-y spective view ofone of the vertical members of said clamp. Fig. 13 is a detail perspective view of the follower-block for the balingchamber. 5 5

Like numerals of reference mark the same parts wherever they occur in the different figures of the drawings.

Referring to the drawings by numerals, 1 and 2 are the sills, aud3 and 4v the plates, of 6o vthe framework upon which the operative parts of the press are mounted. The sills and plates are connected at their outer ends by uprights 5 and 6, said uprights being connected by cross-bars 7, 8, and 9 to properly 65 brace them and fix them at the proper distance apart. 1

At the inner end of the framework the sills and plates are connected by a metallic box 10, which rests upon the sills, while the plates 7o rest upon it, both sills and plate being rigidly bolted thereto. This box 10 is open at both ends and forms the chamber in which the cotton is received ready to be forced into the baling-chamber. The metal bar 11 is prop- 75 erly secured to the box 10 on one side, passed back parallel to the sills and plates at about midway between them, around the uprights 5 and 6, and along the other side in a similar position to be again fastenedto the opposite 8o side of the box 10, serving to reinforce the framework in withstanding the strain due to the operation of the press.

.Upon the plates 3 and 4 are placed trans verse beams 12 and 13, to which are secured 85 nprights 14, 15, 16, and 17, and these in turn are connected by plates or longitudinal beams 18and 19, the whole framework being stiftenedvby braces 2O and 21, secured by suitable bolts to the transverse `beams 12 and 13 and 9o the longitudinal beams 18 and 19.

On the longitudinal beams 1S and 19 are lsecured bearings in which isjournaled a shaft 22, carrying a pinion 23, engaging a' gearwheel 24 on a shaft 25, also j ournaled inbear- 95 ingsl secured to the longitudinal vbeams and carrying a pinion 26, which engageswith the gear-wheel 27 on the crank-shaft 28, likewise journaled in bearings secured to the longitudinal beam.

Upon the crank-shaft 28 is secured the crank 29, which is connected by a pitman to IOO the bar 30, which connects the two sets of toggle- levers 31, 32, 33, and 34, whereby the toggle-levers are forced to move in unison. The crank and crank-shaft are connected in a manner clearly illustrated in Figs. 3, 4, and 5, which will' provide for lost motion between them, for purposes hereinafter specified.

By reference to Fig. 5.it will be seen that the outer end of the crank-shaft 28,which enters the crank-arm, has one half cut away to a smaller diameter than the other half 35, so that when it is inserted in the opening in the crank-arm, as rshown in Fig. 3, a semicircular space 36 will be left around the side having the smaller diameter, into which space a feather 37 projects, so that when the shaft is turned there will be no movement of the crank-arm until one end or the other of the larger diameter 35 of the crankshaft strikes the feather.

The four toggle-levers are exactly alike in construction, being bifurcated or forked and formed with cylindrical ends or journals 38, 39, and 40, as clearly shown in Fig. 6, said journals being provided with end openings to receive screws or bolts 41 and 42, by means of which they are connected together through the medium of links 43, the inner journals of the toggles 3l and 32 resting in semicylindrical bearings 44 and 45 in the lower end of the connecting-bar 30 and the journals 38 of the toggle- levers 33 and 34 resti'ngin similarbearings 46 and 47 in the upper end of said connecting-bar 30.

The pitman 48 is bifurcated, forming arms 49 and 50, which are widest apart on the horizontal plane of the connection between the toggles 33 and 34,'said arms 49 and 50 straddling said toggle-levers at their point of connection and being brought nearly together at their lower ends, where they are provided with openings 51 and are mounted to form journals 52 to fit in semicylindrical bearings 53 in the upper side of the end block of the connecting-bar 30.

The arms 49 and 50 straddle the connectingbar 30, the journals 52 resting in the bearings 53 and a suitable bolt 54 being passed through the opening 5l in the bearings 52 and a registering opening 55 in the connecting-bar, whereby the pitman and connectingbar are pivotally connected.

56 and 57 are the connecting-plates for the outer ends of the toggle-levers and 34, while similar plates 58 and 59 form bearings for the outer ends of the toggle-levers 31 and 32. These plates are all constructed alike, and the illustration in detail in Fig. 7 of plate 58 will serve with its description for all the otherplates. Each of these plates 56, 57, 58, and 59 are provided with semicylindrical bearings 60 near the bottom and 61 near the top. In the rear of these bearings are formed recesses 62 and 63, and suitable bolt- holes 64, 65, and 66 are provided to receive the attaching-bolts. The plates 56 and 57 are secured upon the cross-bars 7, 8, and 9, bringing the bearings 60 of each plate in position to receive .consists of a metallic strap 68, located in the recesses 62 and 63 and having its ends bent inward Vto lie upon each side of the bearingplate, said ends being provided with openings concentric with the curve of the bearing 60 or 6l and registering with the opening 69 through each of the journals 39 and 40. It

will be observed that the joint formed between the toggle- levers 3l, 32, 33, and 34 with the connecting-bar 30 and with the bearing- plates 56, 57, 58, and 59, and the joint between the journals 52 on the lower ends of the arms 49 and 50 of the pitman 48 and the bearings 53 in the lower end of the connecting-block 30 are all knuckle-joints, and the `bolts 41 and 42, which connect the straps 43 with the journals 38 of the toggle-levers, as

well as the bolt 54, which connects the lower end of the pitman-arms with the connectingbar 30, are all concentric with the curves of the various bearings.

The box l0 may be termed the receivingboX or receiver of the press, and the hop per 70 will be mounted above it, in which to deposit the cotton to be pressed into a bale.

j The baling-chamber, which communicates with the receiving-box, has its top and sides composed of four corner- plates 7l, 72, 73, and 74, (see Figs. 1, 2, and 10,) and a suiiicient number of longitudinal side bars or slats 75 76 77 78 79 8O 81 82, eight being shown in this instance, two on each side. These side bars are all formed exactly alike and, with the corner plates, are bolted to the sides of the box 10.

sides and side plates will include the top and bottom of the box 10 and top and bottom bars or slats. Theinner ends of these side bars and the corner-plates are farther apart than their outer ends, whereby the baling-chamber is tapered, being slightly smaller at its discharge end.

A framework consisting of two sides and a top and bottom barincloses the outer ends of the side bars and corner-plates, the side bars being marked 83 and 84, the bottom bar 85, and the top bar 86. each of these four bars is T-shaped, the stem of the T representing the bar itself and theiiange 87 thereof resting atwise against the outside of the side slat-s of the baling-chamber. Each of these bars 83, 84, 85, and 86 is provided with grooves 88, in number to correspond with the number of side slats., intov which grooves angular ribs 89 on the outside'- It will be noted here that the terms IOO lIIC

V1 zo The main body of of the side slats are iitted, as most clearly shown in Fig. 10. One of the side clampingbars 8i, which is a duplicate of 82, is illustrated in detail in Fig. l2. It will be'observed that its ends 90 and 91 are thickened and provided on theirinner sides with triangular recesses 92 and 93 and that its extreme ends are rounded and provided with openings or boltholes 9i and 95. The top and bottom pieces are duplicates of each other, and the top piece 86 is illustrated in detail in Fig. 11. In addition to the details hereinbefore described it will be observed that the top piece is beveled at each end, as at 96 and 97, to enter the triangular recesses 92 and 93 in the side bars 83 and 84, its flat inner flange 87 being cut away at its ends 98 and 99 to rest against the fiat inner iianges 87 ofthe side bars 83 and 84. Upon the top of the top bar 86 and the bottom of the bottom bar 85 are secured saddles or bearing-pieces 100 and 101. In the seats or bearings in which are located threaded rods or bolts 102 and 103 is an angular block 104: at the center of said rods, resting between the saddles A100 and 101 and preventing the longitudinal movement of said rods. Right and left hand threaded ends 105 and 106 pass through the bolt-holes 94 in the ends of the side bars 83 and 8l and are provided on the outside of said bars with nuts 107 and 108. By means of these threaded rods 102 and 103 and threaded ends 107 and 108 .the end frame, consistingof the side bars 83 and 84 and the top and bottom bars 85 and 86, are rigidly secured together, and the proper position of this framework with relation to the length of the side slats and corner-bars is fixed by placing the side bars 83 and 84 between lugs or stops 109, formed on the outside of the corner-bars. In Fig. 13 I have illustrated the follower-block for the balingchamber, which consists of a board or plate 110, preferably rectangular in shape and of a size equal to the end of a bale when pressed and tied. A series of blocks 111 are secured on each surface of this plate, leaving parallel spaces 112 and 113, crossing each other at right angles, as clearly shown. One of these blocks is placed in the baling-chamber in front of the hay, and as the hay is pressed against it it moves toward the end of the chamber until sufficient hay has been pressed in behind it to form a bale, when a second follower-block or separator is inserted behind the hay and the operation continued while pressing hay against the second block, causing it and the iirst block and the inclosed hay to be continued in its passage through the baling-chamber until forced out at the forward end. During the passage of the bale of hay through the baling-chamber suitable binding-wire 1141E is Wrapped about it, being passed through the parallel rectangularly-arranged spaces in the inner sides of the for# ward and rear follower-blocks 110, as clearly shown in Fig. 2. l

The construction and operation of my in' `"ention will be readily understood from the foregoing description.

lVhile I have illustrated and described the best means now known to me for carrying out my invention, I do not wish to be understood as restricting myself to the exact details of construction shown and described, but hold that any slight changes or variations, such as might suggest themselves to the ordinary mechanic, would properly fall within the limit and scope of my invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

1. In a press, the combination of a plunger, toggle-levers connected at one end to the plunger and at the other end to the frame of the press, a pitman pivotally secured to the toggle-joint, a shaft having a recess in one side of its journal, and a crank pivoted on the shaft and having a feather in the recess thereof, substantially as described.

2. In a press the combination of the connecting-bar for the toggles having semicylindrical bearings on each side at its top and bottom, and on the inner side of its head or lower end, the double pairs of toggle-levers, each lever having a cylindrical journal to engage one of the side bearings, links for connecting the levers of each pair and holding them in the bearings, the bifurcated pitman having the lower ends of its forked arms rounded and seated in the last-mentioned bearing, and the bolt connecting the forked arms of the pitman with the connecting-bar concentrically located with reference to the curved bearings, substantially as described.

3. In a press the combination of the side pieces consisting of T-bars having thickened ends with triangular projections in the inner sides thereof, with the end bars T-shaped in cross-section having the en ds of the rib portionbeveled off to enter the triangular re cesses in the side parts, and the ends of the flange cut oif to form shoulders to rest against the inside of the side bars, and suitable means for clamping the side bars and end bars together, substantially as described.
