Application filed July 1, 1914. Serial No. 848,358.

My improved machine, which is indicated generally in Figs. 1 and 2, consists of a cotton feeding device A, a forming device B, a pasting device C, a feeding device D, a cutter E, and duplicate rolling devices F and G.

Commencing with the cotton feeding device A, it consists of suitable frame-members 1 and 2 suspended over the table 3.

The cotton, which is in the form of a flat strip, indicated by 4, istaken from a roll 5 (Fig. 10) carriedby the frames 1 and 2. On starting, 'the cotton strip is fed by hand to the feed rollers 6 and 7, the roll 6 being rotatable only, the roll 7 being rotatable and also vertically movable. The roll '7 is moved vertically by means of cam-disks 8, having cam-spots 9. Adjacent the rolls 6 and 7, I locate a separator or clamping element 10 which acts to aid in the separation of the strips 4, into sections at the proper time. The clamp 19 is actuated by camdisks 11 having cam-spots 12, the said cams being carried by a rotatable shaft 13. The feeding and separating means of the device A consists of a plurality of belts 14, 14 provided with combs 15, 15, the said belts being operated by drums 16 and 17 having recesses 179 (Fig. 14). From the combs 15 the cotton strips pass into a chamber 18 and at certain eriods, as will-be hereinafter described. o operate the elements of the cotton-feeder A, various means can be employed, but I have herein illustrated an overhead driving device 23 consisting of a shaft 24 and pulleys thereon. To avoid undue complexity, the driving mechanism for the elements of the machine have been illustrated by dotted lines. The driving mechanism 23 operates a countershaft 25 and pul-- leys 26, 27 and 28 thereon, the pulley 29 being connected to the shaft 24. To prevent the belts14 from curving between the pulleys 16 and 17 I provide guides 14 14. V

The shaft 30 carries a sprocket-pulley 31,

'- connected by a chain 32 to the sprocket-puljections 19 former.

ley 26 on the shaft 25. The shaft 32 for the roll 7 carries a sprocket-pulley 33 connected by a chain 34 to the sprocket-pulley 35 on the shaft 36 for the drum 17, for the lower combs 15. sprocket gear 37 connected by a chain 38 to the sprocket pulley 27 on the shaft 25. To actuate the upper combs 15 and shaft 13 for the cam-disks 11, I mount upon the shaft 36 a gear 39 meshing with a gear 40 on the shaft 41 for the drum 17. The shaft 41 also carries a sprocket-pulley 42 which, by means of a chain 43, drives the shaft 13 by means of a sprocket-pulley 44 thereon. The roll 6 is operated by a sprocket-pulley 45 on the shaft 41 by means of a chain 46 and pulley 47 on the shaft 48 for the pulley 6.

The various driving devices will be timed to operate to lift the cams 8 to press the roll 7 against the cotton strip when the clamp or separator 10 is lowered to cause the strip 4 to separate or break by 15 on the belts 14 when a predetermined length of the same has been fed to the paper 19. After the section has been formed the roll 7 will lower and with roll 6 will act as a guide.

The paper 19 is fed by hand, at the initial starting of the machine, through the former B, which turns it up or forms it-into the container 49 (Fig. 8) for the sections of cotton 50 made from the strip 4 by the separating device 10. The former B can be made up in various ways, but I have herein shown it as consisting of a plate 51 (Fig. 12) turned over as at 52, the end 53 overlapping the end 54 and spaced therefrom. \Vhen the paper is fed into the former 3 the outer edges thereof will be turned over to overlap as shown in Fig. 12. Within the former B I place a shield 54 to prevent the cotton from bulging or in other Words, to keep it flat while it is passing through the There will of course not be any cotton in the container when the paper is first fed through the former. During the operation of the machine, the paper will be pulled through the former B, to form a continuous container, the cotton being carried along with the paper. The fingers or procatch in the cotton and assist in carrying it along.

he paper passes from the former B to the pasting device 0, one edge of the container being carried over a paste applying roller 55, the other edge being under the roller. As the paper is fed, the roller 55 applies the paper and roller, the paste being supplied by a paste-pot 56. The roller 55 is rotated by means of a sprocket-pulley 57 on its shaft 58, the pulley 57 being connected by a chain 59 to overhead shaft 24.

From the pasting device C the paper The shaft 36 carries a the pull of the teeth paste to the contacting surfaces of passes between the feeding and pressing rollers 59 and 60 rotatably supported by brackets 61. The roller 60 not only rotates, but is moved toward or away from the roller 59 by means of cams 62 on the shaft 63, which cams impinge upon the outer ends of the shaft 64 for the roller 59. The cams 62 are operated by a sprocket-pulley 65 on the shaft 63, a chain 66 and a sprocket pulley 67 on the shaft 25. The roller 60 will be lowered as soon as the container is fed to the rolling device. The roller 60 is operated by a sprocket pulley 68 on a shaft 69 (which will be described hereinafter) through the medium of a chain 70 and sprocket-pulley 71 on the shaft 64 for the roller 60. The roller 59 is driven by a. gear 72 on the shaft 69 meshing with the gear 73 on the shaft 74 for the roller 59.

Adjacent the, feeders 59 and 60, I place the cutting device E which consists of a pivotally mounted knife or cutter 75, Fig. 3, the function of which is to cut the container 49 into strips or sections, which are afterward rolled, into the shape shown in Fig. 9 by the rolling device F and G. As can be seen the cutter 75 is pivotally secured as at 76, to the bracket 61, a spring 77 being used to force the cutter 75 downwardly to sever the strip. The cutter 75 is raised to its high position by a cam 78 operated by a pinion 79 which in turn meshes with an intermittent gear 80 on the shaft 81. The shaft 81 carries a gear 82 meshing with a gear 83 (Fig. 2) on the shaft 63. The cam 78 is turned to permit the cutter 75 to move downwardly and sever the strip as soon as the strip has been fed a predetermined distance. Just before the paper is entirely rolled, the cutter acts. The strip will be engaged by the rolling devices as soon as the end thereof reaches the clamps of the rolling devices after said end has passed by the cutter 75 being fed thereto by the feeders 59 and 60. As soon as the strip is engaged by the rolling device, the shaft 60 will drop, thereby stopping the feeding of the strip by the rollers-59 and 60, the rolling device continuing the feeding of the strip, and as soon as the severed end of the strip, at the cutter, reaches the clamps of the rolling device, it will be grasped thereby and commence to roll up.

As the rolling devices are duplicates, I will describe but one, applying similar refernce numerals to corresponding parts in each. Referring to Fig. 4, the rolling devices consist of a rotatable clamp 84 comprising jaw-members 85 pivoted, as at 86, to retractable arms 87 carried by a gear 88 slidably mounted in a slee'" 89, carried by the bracket 90. The gear 88 is operated in one direction to open the jaws 85 by a spring 91, and in the other direction to close the jaws by a cam 92 rotatably mounted in a standard will have entered 93. The shaft 94 of the cam 92 carries a pinion 94 meshing with an intermittent gear 95, by which means it is driven. The gear 95 is driven by a bevel-gear 96 and bevel pinion 97. The pinion 97 is carried by a shaft 69 (Fig. 2) which in turn is driven from the overhead shaft 24 by means of a sprocket pulley 99 and chain 100.

To open the jaws 85 when the arms 87 are forced backwardly by the spring 91, I employ a spring 101 which, when the arms 87 are retracted, forces the jaws apart, the aws swinging upon the pivots 86. The pinion 94 is driven by an intermittent gear 95 to cause the gear 94 to make one revolution to release the rolled up container and to be ready to roll a new one. When the end of the strip reaches the jaws, they will close upon it, the mechanism being timed for such result.

The rotation of the gear 88 is accomplished by aid of the pinion 102 which is connected to the shaft 103 by a friction clutch 104. The clutch 104 is thrown out by a yoke-lever 105 'pivotally secured to a bracket 106 throu 'h which the shaft 103 passes. The .yokeever 105 is operated by a cam 107 carried by a shaft 108 which carries a gear 109 meshing with an intermittent pinion 110 on the shaft 111. The shaft 111 is supported by a bracket 112. A spring 118 throws in the clutch 104 after the high part of the cam 107 clears the lever 105.

To operate the shaft 111 I secure to the same a gear 113 and to operate the gear 113, I provide a pinion 114 carried by a shaft 115. The shaft 115 carries a sprocket-pulley 116, which by means of a chain 117 (Fig. 1) is driven by the overhead shaft 24. Just before the roll is completed the knife 75 actuates to sever the strip. Simultaneously the jaws 85 will open, releasing the roll of cotton by reason of the fact that the said jaws will be withdrawn by the action of the spring 91; the cam 92 will in the meantime have been rotated out of contact with the sleeve 89. During the rolling operation the said cam will remain in contact with said sleeve. Immediately before the above described operation on the part of the jaws 85, the cam 107 will leave the lever 105, allowing the spring 118 to pull the clutch 106 away from the gear 102, thereby causing the rolling device to come to rest by the time the roll is completed.

To cause'the rolling device to stop in the proper position, I provide a stop-pin 119, adapted to enter a recess 120 in the gear 102. The pin 119 is forced into the said recess by the action of the cam 121 upon the lever 12'). against the tension of a spring 123. The pin 119 will enter the recess 120 just before the clutch 104 leaves the gear, hence by the time the clutch leaves the gear the pin 119 the recess and stopped filling with cotton.

the rolling device. As

further rotation by 121 is carried by the will be seen, the cam shaft 111.

The pasting device 55 (Fig. 7) is of arbitrary construction andis made" up, in this instance, of a plurality of paste-applying rollers 124 rotating in a casing 125. A single pasting-roller may, however, be used. The paste comes from the pot 56 and passes through openings 126 in the neck 127 of said pot. Shortly before the jaws -85 grip the strip or container, said grippin'g being caused by the cam 92, the pin 119 will leave the recess 120 and the gears 86 and 102 will rotate, causing the container to wind up. Thecontainer and its cotton will wind up with a constantly increasing speed, due to itsi'ncreasing diameter. To put a tension on the container, while being wound, I provide the tension device 128 adjacent the winding device (see Figs. 2 and 13). The tension device 128 is orced upwardly against the container by springs 129. While the container is being wound up at one end, the device A feeds cotton to the container or upon the paper which finally becomes the container.

As "the speed of the paper-container will be variable, that is, slow at first and then gradually in'creasingand the feeding of the cotton is constant, it is preferable to provide means to collect or pile up the cotton when its speed is greater than that of the paper, in order that there will be a reserve supply when the speed of the paper becomes greater than the feeding of the cotton. The function of the chamber 18 is to collect the piled up cotton at the time when the speed of the paper container is at its minimum. During the time that the paper-container and its cotton is being wound up to the required size, the advancing paper-container will be When the paper-conhave been wound nearly to the required size, the knife 75 will act to cut the container. We will now have another section to be wound up and cut off at' the next operation of the machine. The -cams 8 are timed to delay the feeding of the cotton strip for another section until the paper-container has been fed slightly in order to leave some free paper to be turned up at the ends to seal the end of the container, and to start a new container.

The function of the feeding rollers 59 and is to deliver the paper container to the jaws of the rolling device. After the jaws of the rolling device have gripped the container, the cam 62 will be rotated sufliciently topermit the roller 60 to drop, thereby preventing tainer and its cotton further feeding of the paper by the said rollers 59 and 60. The actual feeding of the container is accomplished by the rolling device, and not by the rollers 59 and 60 which act only after the cutting operation.

as it is evident the paper will be drawn along or fed as it is wound up.

The spring-door 128 acts as a drag upon the container to cause it to windtightly. As soon as arms 87 are retracted, the slant 87 of grippers will leave rollers 87, thereby allowing spring 101 to open jaws. During the rolling operation the cam 92 will remain as shown, but at about the time that the roll is completed, the teeth of the gear 95 will mesh with the teeth of the gear 94, causing the cam to leave the bushing 89, at which time the jaws will spring open quickly, and at about the same time the rolling device will stop. The jaws will at the proper time slowly close and be ready for the next rolling operation.
