MAGNUS SWENSON, OF CHICAGO, ILLINOIS, ASSIGNOR, BY MESNE ASSIGrN MENTS, TO THE AMERICAN COTTON COMPANY, OF NEW YORK, N. Y.

COTTON-PRESS.

` SPECIFICATION forming part of Letters Patent No. 658,050, dated September 18, 1900.

Application and Aprn 11, 189.5.

F0-@ZZ whom it may concern: Y

Be it known that I, MAGNUs SWENsoN, a resident of Chicago, in the county of Cook and `State of Illinois, have invented new and use- 5 fulImprovements in Cotton-Presses, of which the following is a specification.

This invention relates to improvements in what may be termed rotary cotton-presses, comprising a spool on which a cylindrical bale Io is formed and driven compression-rolls arranged on opposite sides of said spool and adapted to subject the bale formed thereon to the desired pressure. Presses` of this type are specially designed and vadapted for use at x5 the place of ginning in combination with the gin and condenser, the bat of cotton passing directly from the condenser to the press, thus l necessitating but ,a single handling of the cotton. As heretofore constructed, however,

zo presses of this type have been objectionable for the reason that their operation has not been continuous-that is, after the formation of a bale of desired size it has been necessary to stop the gin and condenser while the z 5 bale Was being covered and discharged, Which involved a great Waste of time.

The object ofv the present invention is to provide a press in which the baling shall proceed continuously, thereby obviating the ne- 3o cessity of stopping the gin and condenser. In the preferable form thereof now known to me a press embodying my. invention comprises a middle stationary roll, movable compression-rolls arranged on each side thereof,

3 5 and baling-spools supported on movable centers, one on each side of4 the stationary roll, between said stationary roll and the movable compression-rolls.

' The invention also covers the various other 4o features, combinations of features, and details of construction hereinafter described, and pointed out in the claims.

In the accompanying drawings a press em-` bodying my improvements is fully described.

45 Figure lis a top plan view of said press. Fig.

2 is a side elevation thereof, and Fig. 3 a longitudinal section showing the press in use with an'ordinary condenser for forming a bat.l

Referring now to the drawings, A is the` 5o frame of the machine, in which the operative parts thereof are supported, said frame consentira. 545,303. ci@ modelo sisting of horizontally-disposed side pieces a., end pieces c', connecting the same at their ends, and supporting-legs or standards d2. Supported so as to rotate freelyin suitable bearings formed in the side frame-pieces d is a stationary compression-roll B, on each side of which are arranged compression-rolls B'B2, revolubly supported in suitable bearingblocks b, fitted to and longitudinally movable in guide slotsor Ways b', formed in the side frame-pieces a, and a balingspool B3, supported so as to rotate freely upon withdrawable centers mounted in sliding blocks b2, fitted to and longitudinally movable in the guide slots or Ways b in the same manner as the blocks b, said baling-spools B3 being located between the stationary roll B and the movable compression-rolls B B2. The bearing-blocks b of the rolls B B2 are connected by cross-heads B4, While the blocks b2, supporting the baling-spools, are disconnected and freely-movable independently of each other. In the construction shown the spoolsupporting centers instead of being mounted directly in the bearing-blocks b2 are iitted to bearings formed longitudinal through the hubs of disks B5, Which are fitted to suitable bearings formed in said blocks b2, so that said disks shall be freely revoluble. Rotary movement in the same direction is imparted to the compression-rolls in the following manner: Secured to the shafts of the compression-rolls are spur-gears C C C2, which mesh With pinions C3 C4 C5, secured to pinion-shafts c c c2, of which the shaft c is stationary and the shafts c c2 are mounted in the movable bearing-blocksfb. Secured to the shafts o' c2, respectively, are sprocket-Wheels c3 c, corresponding sprocket-wheels c5 c6 being se cured to the shaft c, and chain belts C6 C7 are adjusted thereto. f

The press is driven from any suitable source of power bymeans of abelt adjusted to a driving-p ulley C8, secured to a shaft c7, a pinion on which meshes with a gear-wheel secured to the shaft c, all in an obvious manner.

To facilitate the discharge of the bale formed between the compression-rolls B B2, means are provided for stopping the rll B2 independently of the other driven parts. This can be effected in a simple manner by driving said roll through the medium `of .a v

clutch mechanism. In the drawings I have shown the clutch as applied to the sprocketwheel c4. In like manner in order to facilitate the discharge of the bale formed on the front spool the pinion C3 is secured to its shaft by means of a suitable clutch. -In dis-5 charging the forward bales, however, it is necessary that both the roll B and the roll B2V be stopped, and this is eifected in a simple! manner as follows: A

The sprocket-wheel ci instead of being secured directly to the shaft c is rigidly secured to a sleeve formed integral with the hub of the pinion C3. Engaging or disengaging the clutch applied to the pinion C3 will thus operate to start or stop the rolls B and B2 simul-I taneously.

In order to provide for movement of the rolls B B2 to form a bale of desired size, the chain belts O6 C7 are much longer than necessary at the initial point in the baling opera-1v tion, and the return side thereof will hangi loose. In the case of the chain belt C7, which drives the rear roll, the duty comes on theZ upper side thereof, the lower side being the; return side and hanging free. In the case of j the chain belt C6, which drives the forwardl roll, however, the duty comes on the lower. side thereof, and the upper side, being the return side, will hang loose, and unless thejl sprocket-wheels are made much larger than! is desirable will when the rolls are close to gether come into contact with the lower section of said chain belt, thus creating a strongj liability of its becoming entangled therewith, as a result of which the press would either be stopped or broken. To prevent this, means are provided for supporting the upper loose section of the chain belt C, as follows:

Pivotally supported between its ends upon the shaft c' is a lever C9, adjacent to one end of which is pivoted an idle pulley es, over which the chain belt C6 passes, said pulley` being preferably provided with guide-flanges, whereby said chain belt will be prevented from running of from said pulley. Secured to the opposite end of said lever C9 is a weight o9, which is sufficiently heavy to counterbalance the pulley and the loose section of the chain belt, and by making the weight adj ustable toward and from the pivotal point of the lever the tension on said loose section of the chain belt may be regulated, as desired, within limits.

The means for generating the pressure on the bale are the same as shown and claimed in an application for Letters Patent heretofore filed by me on the 26th day of March, 1895, Serial No. 543,244, and are as follows:

A rod or bar d connects each of the crossheads Btwith a piston tted to a cylinder D, secured to the frame of the machine in proper position. The end of the cylinder adjacent to the cross-head will preferably be open, and a pipe d' communicates with the closed end of said cylinder. In said pipe d' is a safetyvalve D', which maybe adjusted so as to open at any desired pressure in the cylinder. Preferably, also, water or other substantially-inelastic liquid will be employed to generate the pressure in the cylinder. It is thus evident that as the size of the bale increasesthe pressure thereupon will begenerated automatically.

By forming bales on the spools B 13'2 alternately it is obvious that the baling can proceed practically as a continuous operation, the only occasion for delay being the very short space of time required to discharge the bale formed on the front spool, it being possible to discharge a bale formed on the rear spool without stopping the front baling-rolls. Thus, referring to Fig. 3, showingl an ordinary condenser E for forming a sheet or bat of cotton, it will be noted that the sheet or bat is first directed to the spool between the central roll B and one of the movable rolls and that after the bale is formed on that spool the bat is directed to the other spool and a new bale started thereon. This alternate formation of the bales on the two spools makes it possible to carry on practically a continuous operation, the condenser or other bat-former running continuously.

I claim- 1. The combination with a single bat-forming apparatus, of two sets of rotary cottonpressing appliances to which the bat is alternately fed, a bale being first formed in one of said appliances and then in the other ofy said appliances,whereby the process of forming a bale in either one may go on while a previously-finished bale is being removed from the other.

2. Inacottonpress,three compressing-rolls having their axes substantially in linewith each other, mechanism for operating said rolls to provide for the formation of a bale alternately between the intermediate roll and each of the other two rolls, and a core-rod supported at each side of said intermediate roll.

3. In a rotary cotton-press, the combination of a stationary compression-roll, compressionrolls movable toward and from said stationary roll, movably-supported baling-spools arranged, one between the stationary roll and each movable roll, means to hold the movable rolls yieldingly in contact with their respective baling-spools, or the bale formed thereon, and means to rotate said compression-rolls, substantially as described.

4. In a rotary cotton-press, the combination of a middle stationary compression-roll, compression-rolls movable toward and from said stationary roll, baling-spools arranged, one between the stationary roll and each movable roll, said rolls and spools forming substantially a horizontal series, means to hold the movable rolls yieldingly in contact with their respective baling-spools, or with the bales formed thereon, means to rotate said compression-rolls, means to independently en- IIO 658,056 Y s e gage and disengage the rear compression-roll from the driving mechanism and means to simultaneously engage and disengage the middle and rear compression-rolls from the driving mechanism, substantially as described.
