COTTON-PRESS.

SPECIFICATION forming part of Letters Patent No. 643,995, dated February 20, 1900.

Application filed September 23, 1899, Serial No. 731,403. (No model.)

To all whom, it may concern:

Be it known that I, HENRY L. WHITMAN, a citizen of the United States, residing at the city of St. Louis, in the State of Missouri, have invented certain neviT and useful Improvements in Cotton-Presses, of which the following is a full, clear, and eXact description, reference being had to the accompanying drawings, forming part of this specification.

For the economical baling of cotton at the present day it is necessary to produce a bale of sufficient density in the original operation without subsequently subjecting the bale to the compress, also to make up the bale of a continuous web, and to perform the operation continuously both as to the feeding from the gins and the formation, tying, and delivering of the finished bales. Cylindrical baling has been resorted to as embodying some of these advantages; but this form of bale is objectionable owing to the loss of space and danger from tire resulting from the air-spaces between the bales which it occasions in shipping and storing and because of ill effects which the process has upon the liber. It has been proposed to make rectangular bales of a continuous web; but it has heretofore been impracticable to carry this out in continuous operation in a single press.

The object of my invention is to provide a single apparatus that will receive cotton from a plurality of gins Withoutinterruption, form the cotton into a continuous web or bat, feed the web or bat continuously into a single cotton-box ofacontinuously-operatingpress,and compress the material thus introduced and move it continuously forward to the dischargepoint Without interruption, all these steps being performed Without injury to the fiber.

My invention consists in the features above mentioned and in the details of construction of the various parts of the press, as hereinafter described and claimed.

Figure I is a side elevation of my improved press. Fig. II is a side elevation of one of the boxes in which the web-pressing-roller shafts are mounted, the said shafts being shown in cross-section. Fig. III is an elevation of one end of two of the web-pressing rollers and the driving-Wheels carried thereby.A Fig. IV is a side elevation of one of the bearing-boxes in which the webpressingroller shafts are mounted, the joining pinions on two of said shafts, and the pinions of the shafts by which the endless feeding-carriers are driven.

1 designates the baling-box, the general form and construction of which may be whateveris suitable to receive the reciprocating traverser 2, as no invention is herein claimed, perse, for a baling-box. The traverser 2 is connected to a pitman 3, that in turn is suitably connected to a shaft 4E, driven from a shaft 5, equipped with a drive-pulley 6. I have not attempted to show in detail the mechanism for moving the traverser, as various forms of mechanism may be used for this purpose. A form of mechanism well adapted 'for the purpose is set forth in Patent No. 363,269, issued vto Charles E. IVhitman May 17, 1887. ing-box is to be provided with the usual form of retainers. l

On the shaft@c is a gear-wheel 7, that meshes with a gear-wheel on a shaft 8, that carries a drive-wheel i), which receives the travel 0f an endless drive-chain 10. The drive-chain 10 passes beneath an idler 11 to a second drivewheel 12 on a shaft 13. The shaft 13 carries a pressing-roller 14E.

15 designates journal-box frames in which the shaft 13 is mounted, the said shaft being The bal- IOO backed by a lnovable bearing16, yieldingly held by a spring 17, the tension of which is controlled by a set-screw 18.

19 designates the shaft of a pressing-roller 20, occupying the same horizontal plane as the roller '14. On the shaft 13 is a pinion 21, that meshes with acorresponding pinion (not shown) on the shaft 19, through means of which motion from the shaft 13 is communicated to the shaft 19, whereby the rollers 14 and 20 are caused to travel toward each other. The shaft 13 being backed by the spring 17 is permitted to move away from the shaft 19 when abnormal pressure is created between the rollers 14 and 20 by an excess of' lnaterial passing between said rollers in the manner hereinafter explained. The pressing-rollers being located over the opening of the feed-box permits the web or bat to pass to the feed-opening by gravity, and it folds itself each time the plunger recedes without the aid of mechanical means for producing the folds.

On the shaft 19 is a drive-wheel 22, the purpose of which will be hereinafter stated. At the opposite end of the shaft 19 is a spurwheel 23, that meshes with a spur-wheel 24, mounted upon an upper shaft 25, equipped with a pressing-roller 26. The opposite end of the shaft 25 from that upon which the spurwheel is mounted is equipped with a spurwheel 27, (see Figs. 1 and 111,) that meshes with a spur-wheel 28 on a shaft 29, equipped with a pressing-roller 30. The shaft 29 is backed by a bearing 31, yieldingly held by a spring 32, similar to that by which the shaft 13 is held, the tension of said spring being regulated by an adjustment-screw 33. From the foregoing it will be seen that the shafts are arranged in upper and lower pairs and that the shaft 19 is driven from the shaft 13, the rollers on said shafts turning toward each other. The shaft 19 drives the shaft 25,which in turn drives the shaft 29, thereby causing the upper pair of rollers 26 and 30 to turn toward each other similarly to the lower pair 14 and 20.

34 designates a chute leading to the upper pair of pressing- rollers 26 and 30.

35 designates a framework on which a hopper 36 is mounted,said hopperbeingsustained at its upper end by stays 37.

38 designates an-endless drive-chain that travels on the drive-wheel 22, carried by the shaft 19, and the drive-wheel 39, mounted on a shaft 40, for transmitting power from the shaft 19 to the shaft 40 and actuating the cotton-feed in the hopper. The drive-chain 38 is held taut by an idler 41.

The hopper 36 is composed of two sides 36, connected by cross-bars 36", (see Fig. 1,) and two sides 42, arranged interior of the crossbars 36h, sustained at their lower ends by bracket-arms 43. (See Fig. V11.) The upper end of the chute 34 is connected to the lower end of the hopper sides 42 by straps 44. (See Fig. V11.) On the shaft 40, at the opposite end from that which carries the drive-wheel 39, is a spur-Wheel 45. rlhe spur-Wheel 45 engages a spur-Wheel 46 (see Fig. IV) on a shaft 47, arranged parallel to the shaft 40. The shafts 40 and 47 are mounted in hearings supported by the framework 35. The shaft 40 carries a roller 40a, and the shaft 47 carries a roller 471. (See Fig. V.) On the shafts 40 and 47 are chain-wheels 48, (see Figs. 1 and VIL) that receive endless drive-chains 49, which extend to the upper end of the hopper 36 and over drive-wheels 50, mounted at the upper end of the hopper on shafts 5l. The drive-chains 38 have connected thereto slats 52, (see Fig. VI,) and secured to these slats are endless aprons 53, that travel with the chains, the aprons traveling on the rollers 40 and 47a and similar rollers carried by thc shafts 51.

54 designates a support movably mounted on top of the traverser 2 and connected to said traverser by keepers 55, which engage the lower intnrned edges 56 of the support, (see Fig. XIIL) while permitting a sliding movement of said support on the traverser. The support 54 is box-shaped in form, is open at its rear end, and is constructed with a forward tapering end 57.

58 are bars secured to the traverser at it rear upper end and provided with upturned outer ends 59, that receive slide-rods 60, the opposite ends of which are mounted in ears 6l on cross-bars 62, carried by the support 54.

The object in making the support 54 movable with relation to the plunger is to provide a stationary rest for the bat during the period when the plunger is making the last part of its forward stroke, is com pressing the cotton, and is making the first part of its rearward stroke.

63 is astrengthening-bar that joins the side Walls of the support 54 at its rear end. The support is adapted to travel with the traverser 2 in its forward movement, being held in normal position by springs 64 on the slide-rods 60, bearing against the upturned ends 59 of the bars 58 and against the ears 61 of the cross-bars 62. 1n the forward stroke of the traverser 2 the support 54 is carried therewith, as indicated by dotted lines, Fig. IX. Each forward stroke of the traverser results in the compression of the web of cotton fed into the baling-cha-mber from the compression- rollers 14, 20, 26, and 30, as indicated by dotted lines, Fig. 1X. The web of cotton descends into the billing-chamber from the pressing-rollers in aloop, as seen by the dotted lines, Fig. IX, and as the traverser is carried thereagainst in its forward stroke it presses against the said loop, which is carried therewith and compressed into continuous unbroken folds extending vertically throughout the formed bale. Before, however, the traverser reaches the extent of its forward stroke the corresponding movement of t-he support 54 is arrested by spring-catches 65, that engage in recesses 66 in tho side walls of the IOO IIO

press-box, thereby limitingthe movement of said support. When the support reaches the end of its stroke, it impinges against the Web of cotton descending in the paling-chamber, and the incoming web is held or supported on the tapering forward end 57 of the support until the backward stroke of the traverser occurs, when return movement is imparted to the support and spring catches 65 are withdrawn. As the traverser moves backward theweb of cotton falls 'from the forward end of the support into the baliug-chamber and continues to be fed from the pressingrollers into a loop, as before, to be taken up and compressed on the next succeeding forward stroke of the traverser.

It will be observed from Fig. IX that by the construction of the plunger a space is left between its upper side and the top of the cotton-box, as well as between said portion of the cotton-box and the point at which the support 54 is arrested, and thus provides a passage for the bat, so that it can continue back past the pressing-point, and severance of the bat will be prevented.

67 designates plates carried by the journalbox frames 15. On these plates 67 are guides GS, forming guideways 69, that receive a division-board 70, (see dotted lines, Figs. IX and X,) by which the individual bales of cotton are separated as formed.. The divisionboard 70 is normally supported above the baling-chamber in the position indicated until such time as the formation of a bale has been completed, when it is automatically dropped, as will presently appear.

7l designates slides of angle shape in crosssection which rest upon the inturned lower edges of the plates 67 (see Fig. X) aud slide beneath a heel 7 2, projecting from one of the guides 68. The inner end of the slide 7l is arranged to be projected across the guideways 69 between the guides 68, Where it forms a support for the division-board 70.

7 3 designates springs pivoted to the plates 67 at 74. One end of each of these springs bears against the adjacent guide 68, while the opposite end bears against a stud 71a, carried by the slide 7l, thereby providing for the ac- -tion of the spring against said slide to hold it normally projected inwardly, so as to retain the inner end in position to support the division-board 70.

75 designates a cross-rod that connects the slides at the opposite sides of the press. The rod 75 is pivotally seated in the vertical anges of the slides 71 and carries hooks 76. When suicien't cotton has been fed into the press and compressed therein to form a bale, the operator drops the hooks 76 from a raised position to that seen in full lines, Fig. IX, and on the next succeeding backward stroke of the traverser the said hooks are struck by the rear end of the support 54 and moved outwardly or rearwardly, thereby effecting a pull upon the slides 7l, resulting in the inner end of Said slide being Withdrawn from the lower end of the guideway 69 to permit the divisionboard 70 to descend into the baling-chamber, in which it is carried forward against the end of the bale previously formed on t-he next succeeding forward stroke of the traverser.

In order to prevent damage to the press-box by the division-board and sustain the latter in vertical position in its fall into the chamber, I have provided a pair of spring-controlled arms 77, (see Fig. VIIL) pivoted at 7 S to the press-box and having their free ends extending into the baling-chamber through openings in the side of the box. These arms are backed by springs 79 and are provided with curving upper edges that receive the impact of the division-board as it falls into the baling-charnber. The division-board strikes against the said arms, forcing them outwardly against the action of the springs 79, and descends slowly to the bottom of the balingchamber, against which it rests in an upright position, being held by the said arms until such time as the traverser strikes it and carries it forward against the bale previously produced.

From the foregoing description it will be observed that the bales are tied during the movement of the condensed cotton toward the discharge end of the press, the bale thus formed in front making the press-head for the succeedin g bale, and the bales are delivered in continuous process. I am therefore enabled for the first time to do away with interruption in the feed from the gins, or an interruption in the formation of the continuous web or bat between the feed-rollers, or in the reciprocation of the plunger, and the operation, therefore, while confined to a single press, is strictly continuous. I therefore term the apparatus a continuous press. The cotton is in the desired condition, the form of the bale meets all requirements, and the fiber is uninjured by any part of the process.

It will be understood that the bale is tied in the well-known manner followed in baling hay-that is to say, division-boards are inserted at suitable intervals, baling-wires are passed through. the grooves in the boards and through thc openings in the side walls of the press, and the ends tied before the bale has expanded.
