Fig. 8 is a top plan of the clutch, pinion, and segment for reversing the accumulator. Fig. 9 is a detail section, on an enlarged scale, of the accumulator-roll. Fig. 10 is a detail of the bagging-clamp and its controlling-handle. Fig. 11 yis a detail section through one end of a side bar, show- Fig. .12' isa detail horizontal section of the feedroller.'A Fig. 13 is a side elevation of the tubular union G2; and Fig. 13a, an end View thereof, showing one of the flanged ends removed. yFig. 14 is a side elevation of the pressure-cylinder, and Fig. 14. an end view thereof. Figs. 15, 15:L are detail views showing side elevations of the stationary rollerframes.

Theimain frame of the press consists, essentially, of four .tubular stringers-o'r side pieces A, united' at their front ends by a rectangular cross-frame B,N preferably having downward extensions b, constituting feet or supports. At the rear ends the top and bottom side pieces are connected by upright frames extensions b. J ust insidel the `frame C the side pieces support other verticalA frames,

`which may 'be convenientlyV termed roller- C, having extensions o, corresponding to the frames D D, (shown in Figs. 15,15%) prefer- 95 ably fixed on the side pieces and united to bolted toV the Banged bearing extensions d on the framesy D, as shown in Figs. 2 and G.

Suitable transverse bearings are formed in the framesD for supporting the two stationary pressing-rollers E, such rollers receiving motion through gear-wheels E', carried at one end of the roller-shafts and both meshing with an intermediate gear E2 on an intermediate drive shaft E3, passing through the union Dl and at its opposite end carrying a relatively large bevelgear E, adapted to mesh with a bevel-gearf on the main driveshaft F.

The two movable pressing-rollers G are journaled in frames G', preferably castings, and having concave seats g", formed therein for the reception of the top and bottom side pieces, as will be best understood by reference to Fig. 4. These movable roller-frames are preferably connected by a tubular union G2, corresponding to the union D, but preferably connected with the frames G in such manner as to be capable of affording aslight sidewise play-as, for instance, by forming the bolt-holes in the flanged ends g2 of the union G2 somewhat elongated or of larger diameter than the bolts, as shown in Fig. 13% The flanged ends g2a bear against fianges g3, fixed to the inner-sides of frames G', as shown in Fig. 4, and the latter flanges have boltholes which register with the holes 92C.

The movable pressing-rollers are driven by a gearing corresponding to the gearing for the xed rollers-that is to say, they have gear-wheels g, mounted on their shafts at one end and meshing with an intermediate gear g', carried by an intermediate shaft g2, extending through the union G2 and carrying at its opposite end a large bevel-gear f 3, meshing with a. gear g4, adapted to be driven by the drive-shaft F. This drive-shaft F is journaled in yoke-shaped projections D5-and G5 on the sides of frames D and G', respectively, and in order toimpart rotation to the gear g4 with the frame G5 atany point of adjustvment the shaftis preferably squared throughout a portion of its length, as at F', and the gear-wheel is formed with a corresponding openingthrough which the shaft passes. The shaft F receives its rotation from a large gear F2, with which a small gear F3, connected with the fast pulley of the fast and loose beltpulleys F4, meshes. The pulleys and gearwheel F3 are mounted in a swinging frame FG, having the drive-shaft as an axis, whereby it may adjust itself to a counter-shaft in any position with relation to the press and also take up any slack in the belt. The movable pressing-rollers are advanced, retracted, or held up with the desired pressure by steam-power. For this purpose a cylinder I-I is employed, said cylinder being journaled on vertical trunnions 71. in the end frame B, as shown in Fig. 3, while the piston or ram H takes its bearing against a central boss or flange h on the union G2, which latter, as before stated, may have a slight rocking movement by means of the elongated boltholes in its fian ged ends. With this construction slight twist or pivotal action of the rolls,

especially should the bale be slightly irregular, is compensated for without straining the frame or causing side wear in the gland or on the piston, as will be readily understood.

The bale is adapted to be formed between the four pressing-rollers and also between fiat heads or disks, which give shape and prevent friction to the ends of the bale. These heads or disks (lettered I in the drawings) are journaled to rotate in a sliding frame K, mounted between the top and bottom side pieces, and they are adapted to be advanced or withdrawn, so as to be in position to form the bale ends or so as to release the formed bale by hand-wheels I', the hubs t'of which (see Fig. 5) are threaded into the frames K and in turn constitute the bearings in which the heads rotate. Thus while the heads are free to rotate with the bale as it is formed or pressed they may be quickly and easily retracted to release the formed bale and as quickly set up again for the formation of a new bale.

One of the objects of the present invention is to dispense with the use of a core or mandrel about which to form a bale. To accomplish this object, it is highly desirable that the axis of the heads should coincide at all times with the axis of the bale. In the present press the axis of the heads is maintained at a point equidistant between the pressingrolls by journaling on the hubs of the handwheels or heads equalizngbars or levers L and connecting theends of these bars or levers, by means oflinks L', with the xed frame on the one hand and with the frame of the movable rollers on the other hand. From this it follows that the heads are moved positively and maintained at all times in proper position concentric with the bale. Even in the initial stages of formation the heads are correctly positioned, and as the cotton accumulates between the rollers and pressure is exerted against the heads they begin to rotate and aid in supporting the bale during the subsequent stages of its formation.

The frames D are provided at the top with upward extensions having vertical slot-bearings D therein for the reception of the journals of a feed-roller M, preferably held down against the top presser-roller by springs m, located above the journals and the tension of which may be regulated by set-screws-m'. The feed-roller M is hollow and its inner ends are adapted to receive heads M M. The shaft M2 of said roller is hollowed at each end and provided with ports M3, opening into the interior of said roller, aiordin g communication therewith through suitable swivel connections (not shown) with the exhaust of the pressure-cylinder, whereby the exhaust-steam is passed, by means of a suitable hose or pipe, (not shown,) to and through the cylinder, heating it, for the purposes hereinafter mentioned.

The cotton-bat is fed in over the table N by means of an endless belt N', which at the taneously passesit down vbetween the four pressing-rollers under pressure, excluding the forward end 'passes around a roller N2, journaled in proximity tothe roller M. The two rollers M and N2 therefore insure thefeeding' ofthe bat to the pressing-rollers, and the roller M,Wrkin'gwith considerable pressure against the top' pressing-roller, subjects the'bat to a preliminary compression, heats it, and simulair as the bat is pressed into bale form.

The cotton-bat is supplied from the conf denser continuously,'and as the bale reaches the desired size' and weight an accumulator.

the machina accumulator consists ofl f a roller O, having teeth in one side so setthatl when the roller'is dropped down on the bat said teeth will `pick-the batlup and separate that portion from the preceding portion, as

shownin'Fig. l, The belt continuing tomo-ve causes the accumulator-'roller to rotate andV windthe bat about it until lthe press is ready for the formation of a' newbale,wheri therollerl is raised and the bat allowed to `i'eed'forward` under the roller until itis caught by'the roller M and fed'downbetween the pr'ejssing-rolls.v

. Thev pull thus given 'to the bat Ion the accuf mulator-roll gives the roll a reyerse rotation,v

causing it to discharge its bat, which feeds along ontop ofthemainfbat andis incorpo` rated into the bale.

Various mechanisms may be employed for securing the reversero'tationiof the accumulator-rollgf but 1 prefer to reverse the position of the roller end forend andallow it to drop down onto the bat and belt, when it will unwind itscotton and layit smoothly on the" mainbat.

For the purposeof handling the accumulator-roll inthis'way it is journaled in aU- shaped frame P, centrally journaled at pon a secondA frame P the latterI 'in turn being journaled in` brackets P2, secured to the belttable or other suitable support.

If'the frame P"be turnedf up, the frame P and accumulator-roll may be'turned end for end and again lowered,l and I prefer' to em? ploy mechanism for raising the frame and automatically reversing the roller. The means forraising the frarnePf consists of a pulley p, secured to theframel"v and connected by a loose belt pf with a 'pulley p? on the end of the cross-shaft E3 Witha tightener p3, whereby the pulley p 'may belpartially rotated and the frameraised'by simply 'tightening the belli. l l

' The frame P supports a cross-shaft Q, held against rotation by brackets 1', and this shaft pinion Q3 on a shaft Q4, 'connected`fa'xially with the frame P,' is adapted to m`esh. The, pinion Q3 is loose on th'eV shaft Q4 and is adapt- The clutch is formed by a simple ratchet-collarQ5; keyed to the shaft' and held-in mesh with a ratchet-face on the pinion bya sprigtQ. With this' construction the lupwar'dl move# mentor swing of the frames P and P causes thepinion to'engage the segment and the framePv to rotate a half-turn; but as the frames descend the ratchet connection prevents frame P'fromrotating reversely,and consequently the roller isE reversed end'for end. To again cause the roller to engage and accumulate the bat', it is/ag'ain reversed, only this time it'is reversed while 'empty.""It' will be understood that the 'teeth are so pointed or shaped that they will2 engragethe bat when the'roller is in one position,'but Will'draw out of v'and not pick up the bat when the roller is intheother position."

j. Baggig for 'coyering the bale'is supplied from-a reel convenientlyarrangedwith A'ref- 'erence to the` 4machine and passes through clampingjaws R on the ends of arms R,j`our' jnaled in brackets R2 on'the side frames, adapt# ed to be oscillated by'ah'and-le R3. The endet the bagging R4 dependsfrom the clamp, and as thebale is finished* the clamps fare delpressed,allowing the end lofthe baggingbtrl bei caught between the` baley and'uppe'rjroll of the stationary rolls, as shown 'in-Fig; j1-,f and drawnaround .thebalebythe action of theffour pressing-rolls. YAsrthe clamps areunder tension, the bagging is held tautjan'd the rollsthereforedraw it'tig'htlyfaround theL bale. Whenthe bale has completed 'a4 revolution, the clamps are elevated to-draw out a new 'depending' portion andthev bagging se'vf- 'ered. The twoends on the bale are now fastened together, whenk thebale is jready to be discharged, which Yis'done by turning the ing the pressure-rollersjbak- IOO even shouldfthe vc'ontrol'-'valves be opened to`I kBy reference to Fig. 11 it will be seen that the side barsl are connected ywithv tliejend frames' by being let yinto sockets therein, the Sidebars'beng shoulderedat wjand the' whole frame 'is' held together bytie-rods tu, extending through the sidebars and' having hers or disks and'fnutswgapplied-to theirends outside fjthe end frames; t

To'insure the parallel advance dft'he mbfv iab'lerollers, the frames G may be providedl 4with downward extensions `Y, adapted It`o iform bearings for a cross-shaftYQfon which shaftgear-wheels or pinions Y2 are rigidly mounted. These pinions Y2 mesh in racks YS, secured to the under side bars A and serve, as j ust stated, to insure the parallelism of the rollers in their back-and-forth movements.

It will be seen that the tubular unions D and G2 aiford a housing for the shafts E3 and g2, making the bearings dust-proof, the frame more compact by utilizing the shafts as crossties, and also facilitates separating the parts for shipment or for access thereto for purposes of cleaning, repair, or renewal.

In operation steam is admitted to the rear end of the cylinder by moving the bar S' in the proper direction, thereby bringing the pressing-rollers together', and in the formation of the bale the elastic tension of the steam in the rear end of the cylinder determines the density ofthe bale,for in the formation of the bale the movable pressing-rollers are forced back against the pressure of the steam in the cylinder. The bat is fed in over the table N', down between the feed-rollers,'.and into a space or pocket formed between the four pressing-rollers, where it is rolled into a cylindrical mass which is conned at the ends by the movable heads I. As the size of the bale increases and the movable pressing-rollers retreat the heads move proportionately through the described connections, whereby the centers of the heads are maintained in alinement with the axis of the bale at all times. The bale having reached the desired size,the accumulator-roll O is lowered into engagment with the bat, or if it has been runningin contact therewith in inoperative position it is reversed, so as to cause its teeth to catch or engage the bat, sever it, and by contact with the belt be rotated, so as to wind the bat about itself. The portion of the bat forward of the point of severance winds in about the bale, and when completely wound in the bagging-clamp is 10W- ered, permitting the end of the bagging to catch between the upper roller of the stationary rollers and the bale which draws the bagging in contact with the other pressingrollers and so around the bale. At this moment the operation of the pressing-rollers is stopped byshifting'the driving-belt or otherwise, the bagging severed, and the ends united by sewing or fastening. This completes the formation of the bale in the machine, and the movable pressing-rollers may be backed o by admitting steam to the forward end of the cylinder-and the bale released by backing 0E the heads I through the medium of the hand-wheels I I, when it may be removed from the press. In the meantime the bat has been accumulating on the accumulator-roll, and when the pressing-rolls have been brought together belt p is tightened, thereby raising the accumulator-frames P P', and by the engagement of the gear-wheel Q3 and segment Q2 the frame l) and the accumulator-roll and the bat carried thereby are given a-halftl1rn bodily and lowered into operative position, when the accumulator-.will unwind its bat on top of the bat which is being fed forward by the belt. Thus the two layers of bat are conducted by the belt to the feedrollers. After the accumulatorroller is relieved of its bat it may be slightly raised, or, if desired, allowed to continue to run in contact with the bat in inoperative positionthat is, with the teeth so inclined that they will not engage with or catch the bat. As the bat is passed down between the four pressing-rollers the Aroller M heats it suiciently to soften the liber and adapt it to pack closer under the pressure of the pressing-rolls as they simultaneously wind the bat under pressure into the bale.

The headsl support the ends of the bale during its formation, and being revoluble as soon as the pressure of the sides or edges of the bat is sufiicient to cause frictional contact with the heads it causes them to revolve with the winding bat during formation of the bale, and thus prevent friction and injury to the fiber at the ends of the bale.
