  • This invention relatesto' improvements in cotton-presses, and provides a press which is capable of taking the cotton right from the gin or condenser and compressing it intoa bale of great density and of substantially rectangular shape and which is so simple in operation and so economical of power as to be adapted to the use of the ordinary cotton:
  • the fibers are torn and matted, and the air confined in the bale not only renders it more readily inflammable, but not being able to escape is compressed, making the bale strongly elastic and difficult to compress and confine to its compressed limits. It has in fact been found that the cotton can be com pressed to a greater density with less power and in a condition wherein it will form a compact and substantially inelastic bale by di- 1 rest compression of the bat as it leaves the. condenser into the form of a dense strip,
  • FIG. 1 is a somewhat diagrammatic side elevation of a cotton-press embodying my invention, showing the general relations of the several parts to one another and to the condenser of a-gin.
  • FIG. 2 is a top view of the apparatus, including the compressing-rolls and the baling-press.
  • Figs. 3 and 4 are respectively a side elevation and a vertical section of the baling-press in the condition of operation.
  • Fig. 5 is a side view of the baling-press as it appears after the bale is formed and clamped, the box wherein the' bale is formed having been lowered.
  • Figs. 6 and 7 are respectively side and top views of the bat-folding apparatus, and Fig. 8 shows a detail thereof.
  • Fig. 9 shows the compressed and clamped bale and the plunger-plate above but removed from same.
  • Fig. 10 shows the completed bale.-
  • Myimproved machine comprises three main portions-namely, a series of I'OllGX'S for successively compressing the bat until it reaches a maximum density, a folding or laying apparatus for folding it into the press-box, and a pressing device for compressing the successive layers into the box.
  • 1 2 3 4 5 6 representthree sets of rollers 'journaled in a suitable frame 7 and driven by appropriate gearing, as by gear-wheels 8 and The distances between these rollers are adjusted and determined by suitable adjusting devices, such as adj listing-screws 10, applied to the bearings 11 of said rollers, and the distance is greatest from the first set of rollers 1 2 and successively less for the following sets.
  • suitable adjusting devices such as adj listing-screws 10
  • the bat (represented as coming from the condenser 12 of a cotton-ginning apparatus) passes between these sets of rollers in'succession, and is thus gradually and suecessively compressed. A much more uniform and dense'c'ompression-is thus attained than would be possible with a single set of rollers.
  • the continuous and compressed bat proceeds to the folding apparatus, which is placed in the part of the baling apparatus adjacent to the plunger and serves to fold the bat in layers into the pressbox 16.
  • the bat after leaving the rolls aforesaid first passes over a pusher roller or rod 17,
  • a reciprocating slide 18 which causes said pusher 17 to travel back and forth above the press-box, and thus to lay the bat in successive layers or folds'into the pressbox.
  • This reciprocating slide is operated by a connection-rod and crank connection from a shaft 13, driven by pulley 14, which is operated by belting or in any suitable manner, so as to be set in operation when required.
  • the press-box 16 slides vertically in a frame 19, and a supporting-platen 20 slides vertically within said press-box, being supported and actuated by a screw 21, the term vertically being here used in the sense of perpendicular to the plane of the platen and the term supporting, as applied to'the platen, referring to its function of supporting the cotton against the compressive action of the plunger.
  • the screw 21 is in turn supported and actuated by a nut 22, which is driven through gears 23 23 from driving-shaft 24.
  • Two sets of driving-pulleys 25 26 are provided for this shaft the pulley 25 serving to drive the shaft slowly for the movement of the platen 20 away from the plunger and the pulley 26 reversing the motion and givinga comparatively rapid upward movement.
  • Each of these pulleys has a loose pulley 27 or 28 and suitable beltshifting devices for throwing it out of action.
  • the box 16 is also provided with means for moving it toward and away from the plunger, such means consisting, for example, of a rack 29 on each side of the box, pinions 30, engag ing with said racks, worms 31 onshaft 32 driving said pinions, and suitable direct and reverse driving-pulleys 33 34. on said shaft, a loose. pulley 35 and belt-shifting mechanism being provided to enable the said box 16 to be raised or lowered or held in either position.
  • a plunger 36 guided in the frame so as to reciprocate vertically-that is,in a direction perpendicular to the plane of the plungeris operated by cranks 37 on shaft 38, which is journaled in the frame and carries a fly-wheel 39- and fast and loose pulleys 40 and 41, said cranks beingconnected to the plunger.
  • plunger is shown in I Fig. 9.
  • Belt-shifting devices are also provided for these pulleys, whereby the motion of the plunger may be arrested or-started, as required.
  • Arms 63 pivoted to the side of the frame, can be dropped or'turned onto the guiding projections 15 of the plunger when the latter is in its lowest position,-so as tolock, it in that position.
  • This plunger makes an up-and-dowu or reciprocating stroke for each to-and-fro movement of the pusher It, the plunger coming down onto the bat just as the pusher retreats to its innermost position-that is, nearest to the compressing-rolls 5 6.
  • a plate 42 is attached to-the bottom of plunger 36 by means of swiveled bolts which enter slots 44 in the plunge a secured by hand-nu s 45 and a Plate 46 Tests stituting retaining devices for the bat.
  • the plunger 36 also carries fingers 57,.which engage with arms 58 on the pivoted comb or clamp 48 as the plunger descends,
  • this folding and compressing apparatus is as follows: The box l6, 113V:- ing been run up to'the position shown in Fig. 1 and the supporting-platen 20 also having been run up to its highest position and the plunger being raised, the lower piece of bagging is placed on the supporting-plate, the
  • the bat is fed continuously through ,the compressingrolls 12 3 4 5 6 and is laid down layer after layer by the pusher 17, each forward movement of the pusher carrying a loop of the bat to the outer end of v the box 16, where it is caught .by the clamp or comb 48, and the back movement of the pusher then throws the arms 49 out.
  • the plunger 36 comes down and compresses the two layers thus deposited on the platen 20, and as said plunger rises the slide 18, having completed its inward movement, allows the arms 49 to fly in over the uppermost layer of the bat and to form which the pusher can carry the bat.
  • the platen 20 has been gradually, under theoperation of its supporting-screw, withdrawn from the plunger, and this operation is so adjusted that the fall .duringone about equal to the eventual thickness of two. layers of the bat.
  • the folding device keeps piling in additional layers of the bat they are pressed down successively by theplunger and the supporting platen falls snfficiently to make room for the next layers, and so the operation proceeds until the box isfull.
  • the apparatus is then stopped. 'lhe upper piece

  • bagging or covering of some sort. will be applied to the bale, the same being partly inserted at the bale is commenced and partly laid on top the bale before the plungeris brought down for the last time, the covering then being drawn together and the ties placedover it.
  • a distinguishing feature in the operation of this machine is its graduated-action, where by the cotton is compressed and the air removed from same in three well-defined steps.

  • the folding of the cotton-bat is elfected at a time when the plunger has been raised or withdrawn so far as to be completely free of the cotton and of the folding apparatus, so that the latter can pcrate freely and without any resistance from the plunger, and also that the folding apparatus is then entirely withdrawn from the path of the plunger, so that the latter can operate without interference therefrom.
  • folding apparatus and the com pressing-plunger are thus brought into action alternately.
  • the action of the folding apparatus might lay down more than one fold between the successive operations of the plunger and, on the other hand, that each action of the plunger-might efiect severalcom' pressions between the successive actions of the folding apparatus.
