LOUIS GRIMOND MAOINTYRE, OF BROUGHTY FERRY, SCOTLAND.

PREPARATION OF JUTE AND OTHER FIBERS FOR SPINNING.

Application filed September 24, 1914.

To all whom it may concern Be it known that I, LOUIS Gnnroxp IVIAC INTYRE, a subject of the King of Great Britain, residing at Broughty Ferry, Forfarshire, Scotland, have invented certain new and useful Improvements in the Preparation of Jute and other Fibers for Spinning, of which the following is a specification.

At present, in the preparation of jute fibers for spinning, it is usual to deliver the sliver from the breaker card into cans and take the cans either directly to the finishing card or to a balling machine from which the balls are then taken to the finishing card from which, again, the sliver is delivered into cans and, thereafter, the sliver is taken, in succession, to the first drawing frame to be drawn, then to the finishing drawing frame and then to the roving frame, cans being employed in each case. In this process much labor is required when dealing with the various cans and transferring the same from -machine to machine. Further, although it has heretofore been proposed to make balling machines with means for automatically discharging the balls from the centers, yet at present it is general to use balling machines in which the sliver is wound upon wooden or other centers or mandrels which, when the balls are conipleted, have to be manually removed from the machine and conveyed, with the balls, to the finishing card from which they have to be conveyed back to the balling machine when the sliver has been wound therefrom. Much labor is involved in conveying the centers from machine to machine.

The object of the present invention is to obviate, as far as possible. the use of cans in the preparing process and of removable centers in the balling of the sliver and to attain this object I. under the present invention, deliver the sliver from the breaker card to balling mechanism, then to the finishing card, the first and second drawing frames and the roving frame in succession, the sliver from each machine being balled by balling mechanism instead of being delivered into cans.

The balling mechanism employed may be embodied in separate machines suitably situated adjacent the breaker card, the finishing card and the other machines employed in the process, or it may be constituted by mechanical devices built into, or attached to, the machines or it may consist of a suitable combination of both the aforesaid arrange Specification of Letters Patent.

Patented May 2, 1916.

Serial No. 863,306.

mentsQ Preferably, a separate balling machine is employed in conjunction with the breaker card and finishing card while me chanical balling devices are built into, or attached to, the other machines employed in the preparing process with the exception of the roving frame.

In order to obviate the use of loose or removable centers or mandrels in the balling process the sliver is wound, preferably, cylindrically or spirally, upon centers or spindles which are made in parts and which, when the ball is complete, are automatically moved apart so that the ball may be readily removed by mechanical means or otherwise. The parts are, preferably tapered so as to be more readily withdrawn from the balls while means, such as gilling pins, is provided in connection therewith for insuring that the sliver shall be gripped thereby and these pins may be capable of withdrawal within the parts. The parts may be in the form of truncated cones projccting inwardly from the centers of parallel disks and mav be driven at a varying speed so that. as the ball increases in diameter, the peripheral velocity thereof will remain practically constant while mechanism is, preferably. provided whereby, when a predetermined length of sliver is wound into a ball the centers are automatically withdrawn therefrom and the ball discharged from the machine.

The features of novelty constituting the present invention are pointed out in the claims at the end of this specification.

In order that the invention may be clearly understood reference will now be made to the drawings appended hereto and forming part of this specification and whereon:

Figure 1 is a diagrammatic view of an arrangement of the machinery for carrying out the process when preparing iute for spinning. Figs. 2 to 7 are views of a balling machine, constructed in accordance with the principles of this invention and shown simply by way of illustration or example, suitable for use in the preparation of jute or other fibers for spinning. Figs. 2 and 3 being elevations viewed from opposite sides of the machine. Figs. 4: and 5 plans. Fig. 6 an end elevation viewed from the end A, Fig. 1, and Fig. 7 a detail to an enlarged scale.

On the drawings like reference numerals indicate the same or similar parts throughout the several views while certain parts have been omitted from each view of the balling machine for the purpose of clearness.

WVhen preparing jute for spinning 1 prefer to arrange the machinery in the manner shown at Fig. 1 where A is a barrow of raw jute, B the breaker card, C the finishing card, D the first drawing frame, E the second drawing frame and F the roving frame. With this arrangement the sliver c is fed from the breaker card to a balling machine G, of the construction shown at Figs. 2 to 7, by means of which it is formed into balls which are taken to the finishing card C. One of the balls is shown at y. The sliver m from this machine passes to a second balling machine H, this balling machine being the same as that shown at G, but shown in side view, the sliver passing through a guide funnel z to the balling machine. The balls from the machine H are taken to the first drawing frame D, one of the balls being shown at y and, from this drawing frame, the sliver passes to a third balling machine I, the balls made by which are transferred to a second drawing frame E one of the balls being shown at 3 and, from this frame, the sliver m passes to another balling machine J the balls from which are conveyed to the roving frame F. One of the balls is shown on the roving frame at y and from this machine the rovings pass, as shown, to the bobbins 2 in the usual way. It will be seen, with this process of preparation, that no cans are used, the sliver, in each case, being balled instead of being delivered into cans.

The balling machine illustrated at Figs. 2 to 7 of the drawings comprises a base plate 10 having side frames 11 thereon in which are mounted, in axial alinement, bearing bushes 12 (see Fig: 7) carrying hollow journals 13 having shoulders or stops 14 and feather keys 15 at the interior thereof and sprocket wheels 22 secured on the exterior thereof. Co-axial with the hollow journals 13 are spindles 16 journaled in bearing plates 17 on the frames 11 and carrying collars 18 recessed for the reception of the keys 15 and slidably mounted in the hollow journals 13. Integral with the spindles 16 and projecting from the juxtaposed faces of the collars 18 are truncated cones 19 having pins 21 projecting therefrom and cylindrical portions at the bases thereof while, secured on the opposite ends of said spindles, are grooved collars 24. The cylindrical portions 20 are slidably mounted in openings in metallic disks 23 secured to the hollow journals 13 which are of such length that, when the collars 18 abut against the disks 23, the apices of the truncated cones 19 contact, or nearly contact, with one another.

J ournaled in bearing brackets 25 on the base plate 10 is a main driving shaft 26 carrying bevel pinions 27 and 28 and a sleeve 29, the two former being secured to the shaft 26 While the latter is rotatably mounted thereon. Secured on the sleeve 29 are a. bevel pinion 30 and a pair of sprocket wheels 31, the former being connected with the bevel pinion 28 by means of a pair of differential pinions 32 carried by a hollow spur wheel 33 while the latter are connected with the sprocket wheel 22 by driving chains 34. Journaled, in bearing brackets 36 on the base plate 10, is a shaft 37 having a bevel pinion and pinion 38 secured thereon. The bevel pinion 35 meshes with the bevel pinion 27 on the shaft 26 while the pinion 38 meshes with an idle pinion 39 carried by a pin 40 adjustably mounted in a slot 41 in an extension 42 of one of the brackets 36. The idle pinion 39 meshes with a spur wheel 43 secured on a shaft 44 journaled in bearings 45, carried by a side frame 11, and a bracket 47, mounted on the base plate 10. Secured on the shaft 44 are a worm 46 and bevel pinion 48, the latter meshing with a bevel pinion 49 secured on a shaft 50 journaled in bearings 51, carried by a side frame 11 and the bracket 47. Secured on the shaft 50 is a bevel pinion 52 meshing with bevel pinions 53 and 54, the former of which is securely mounted on a vertical shaft 55 carried in a foot step bearing 56 on the base plate 10 while the latter is secured to a friction disk 57 rotatably mounted on the shaft 55. Between the friction disk 57 and a corresponding friction disk 58 secured on the shaft 55 is located a friction wheel 59 slidably and non-rotatably mounted on a shaft 60 and having a grooved extension 61 thereon with which engages a collar 62 secured to a bracket 63. The shaft 60 is journaled in a bracket 64 on a frame 11 and has a bevel pinion 65 secured thereon which engages a bevel pinion 66 on a shaft 67 journaled in a bearing 68 (Fig. 4) and carrying a pinion 69 engaging the hollow spur wheel 33.

The worm 46 meshes with a worm wheel 70 rotatably carried by a pin 71 adjustably mounted in a slot 72 (see Fig. 2) in a side frame 11. Secured to the worm wheel 70 is a pinion 73 engaging a spur wheel 74 secured on a shaft 75 journaled in the side frame 11 and having a cam 76 securely mounted thereon. Engaging the periphery of the cam 76 is a roller 77 mounted at the free end of an arm 78 secured on a rocking shaft 79 journaled in the side frames 11 and having arms 82 and 83 secured thereon. The arm 82 has a roller mounted at the free end thereof and engaging the end of a rod 81 rectangular at its lower end and slidably mounted in guides 84 on a frame 11. The upper portion of the rod 81 is reduced and has a collar or stop 85 thereon between which and the uppermost guide 84 a spring 86 is compressed. Mounted on the rod 81 is a pin 87 engaging a slot 88 in a bell crank lever 89 loosely mounted on a shaft 90 journaled in the side brackets 11. Mounted on the bell crank lever 89 is a pawl 92 engaging the teeth of a ratchet wheel 93 securely mounted on the shaft 90 on which are also secured spur wheels 91 meshing With spur wheels 94 carried on pins projecting from the side frames 11 and engaging pinions 95 secured on spindles 96 journaled in the side frames 11 and having grooved cams 97 (one only being shown at Fig. 6) securely mounted thereon. Engaging the grooved cams 97 are pins 98 projecting from arms 99 pivoted in brackets 100 on the side frames 11 and having bifurcated portions 101 formed thereon through which pins 102 project into the grooved collars 24.

Pivoted, at 108, to the rod 81 is a link 109 pivoted to an arm 111 secured on a shaft journaled in the frames 11 and on which is also secured a pair of arms 112. The arms 112 are pivotally connected to rods 115 having stop nuts 116 thereon and slidably mounted in levers 117 fulcrumed to the side frames 11 at 118 and having pins or projections 119 thereon resting upon arms 120 which, in turn, rest on springpressed pins 122 slidably mounted in brackets 123 on the frames 11. The arms 120 have stops 121 thereon which are adapted to contact with stops 123 on the grooved cams 124.

Pivoted to the arm 83 (see Fig. 6) is a threaded rod 103 having nuts 105 thereon and engaging one arm of a cranked striker rod 104 which bears against the nuts 105. and is pivoted on or about a shaft 106 mounted in the side frames 11 and has a striker plate 107 formed at the extremity of the other arm thereof. The striker-rod is pressed into contact with the nuts 105 by a spring 113 compressed between one arm of said striker rod and a stop 114 on a rod 152 projecting from a frame 11.

Rotatably mounted on a pin or stay 125 connecting the side frames 11 are arms 126 carrying a bracket 127 in which a drum 128 is rotatably mounted between non-friction roller bearings 129. Pivoted, at 130, to the arms 126 are rods 131 having racks. 132. formed at the lower ends thereof. en gaging spur wheels 133 mounted on pins 134, carried by the side frames 11. and engaging pinions 135 secured on a shaft 136 journaled in the frames 11 and having a grooved cam or scroll 137 secured thereon. (In Figs. 2 and 3 the center line 137 of the groove only is shown). Engaging the roove of the cam 137 is a pin or roller T38 mounted on a rod 139 connected with a rod 140 which, in turn. is connected with the bracket 63. Adjustably secured to the arm 139 is a channel iron 153 (see Fig. 4) to which are secured a pair of arms 154 ad justably and turnably secured, at their upper ends, in slots 155 formed in brackets 156 carried by the frames 11.

In operation, the shaft 26 is driven in any suitable and well known manner and, through the medium of the diflerential gear. drives the sprocket wheels 31 which through the medium of the driving chains 34 and sprocket wheels 22. rotate the hollow journals 13 and truncated cones 19. The rotation of the shaft 26 transmits movement. through the medium of the bevel pinions 27 and 35. shaft 37. spur wheels 38 and 43, and pinion to the shaft 50 which, in turn. causes the bevel pinion to rotate the friction disks 57 and in opposite directions. through the medium of the bevel pinions and 54 and shaft Slirer may be fed automatically in any well-known manner onto the truncated cones 19 and is caused to adhere thereto bv the pins 21 and. as the ball increases in diameter, it causes the arms 126 (through the medium of the drum 128 which bears on the ball) to turn about the shaft 125. thereby raising the rods 131 and causing the racks 132 to rotate the spur wheels which. in turn, turn. the shaft 136. through the medium of the pinions 135. and so cause the cam 137 to move the rods 139 and 140 and bracket 63 in the direction of the arrow (1. This movement of the bracket 63 causes the friction wheel to move toward the peripheries of the friction disks 57 and 58 and thereby cause the speed of rotation of the shafts 60 and 67 to accelerate. This change in velocity of the speed of rotation of the shaft 67 is transmitted to the hollow spur wheel 33, which causes the differential pinions 32 to overrun the bevel pinions 28 and 30 and thereby reduce the speed of the sleeve 29 and sprocket wheels 31 thereon which then rotate the truncated cones 19 at a lower ve locity and so insure that the peripheral speed of the ball of sliver shall remain pract-ieallv constant for all diameters. The rotation of the shaft 44 causes the worm 46 to turn the worm wheel 70 which, through the medium of the pinion 73. rotates the shaft 75 and causes the cam 76 to depress the roller 77 and so cause the arm 78 to rock the shaft '79. This movement of the shaft 79 causes the arm 82 to raise the rod 81 and compress the spring 86 and so cause the pawl 92 to override certain teeth of the ratchet wheel 93 and. simultaneously, causes the arm 83 to move the rod 103 downwardly so as to allow the striker arm 104 to turn about the shaft 106 under the action of the spring 113 and so cause the striker plate 107 to move away from the cones 19 as the ball increases in diameter.

The cam 76 is so constructed that, when a predetermined amount of sliver has been wound upon the truncated cones 19, it completes one revolution and thereby releases the spring 86 which forces the rod 81 downward and thereby causes the pawl 92 to r0- tate the ratchet wheel 93 which, through the medium of the shaft 90, rotates the spur wheels 91 which, through the medium of spur wheels 94 and pinions 95, rotate the grooved cams 97. and thereby swing the arms 99 about the bearings 100 and withdraw the truncated cones 19 from the ball of sliver and into the hollow journals 13. As the rod 81 moves upward the stop nuts 116 cause the lever 117 to depress the arm 120 and so move the stop 121 out of contact with the projections 123. consequently the aforesaid rotation of the cams 97 is possible. Immediately the projection 123 is moved beyond the stop 121 said latter is again raised by the spring-pressed pin 122 and moves-into the path of rotation of the diametrically opposite stop 123, thereby preventing the cams 97 from making more than half a revolution. lVhen the truncated cones 19 are withdrawn into the hollow j ournal 13, as aforesaid, the collars 18 abut against the internal shoulders 14 and move the journal 13 against the bearing plates 17 thereby drawing the disks 23 apart and freeing the ball of sliver. The rocking movement of the shaft 79, caused by the release of the spring 86. also causes the arm 83 to raise the rod 103 and cause the stop nuts 105 to force the striker plate 107 against the ball of sliver and discharge it from the machine. As the ball is discharged the arms 126 return to their original position, as indicated on the drawings, thereby causing the cam 137, through the medium of the rods 131, racks 132, spur wheels 133 and pinions 135, to return the friction wheel 139 to its position nearest the center of the friction disks 57 and 58 thereby causing the differential gear to increase the speed of rotation of the sprocket wheels 31 to their maximum ready for the winding of a further ball of sliver which immediately commences as the sliver feed does not cease.

Although I have referred to the sliver as being made into balls (technically so called) the more correct expression would be short cylinders.
