Abstract: 20,589. Stubbs, W. T., and Stubbs, J. H. Sept. 24. Reeling cords and twine.-Consists of a machine for winding cord, twine, or the like on to cylindrical or conical bobbins or tubes. The paper or other tube, on which the cord is to be wound, is placed upon an elastic sleeve b<1>, Fig. 3, on a mandrel b and the sleeve is expanded by means of a taper nut b<2> to secure the tube. Each mandrel b is attached at one end by a socket-and-pin joint to a rotatable spindle e which is mounted in the side a' of a cradle a. The other end of the mandrel is removably held in a notch in the side a' of the cradle by a plate spring. The spindle e is rotated by means of a chain-wheel g and a chain h from a chain-wheel i on the driving-shaft d. The wheel i is loose on the shaft d, along which it may be moved to cause a projection i<1> on the wheel to engage a projection j<1> on a collar j fast on the shaft, the wheel i being thereby driven. The wheel may also be moved in the opposite direction to cause a projection i<2> upon it to engage a projection k on the cradle a in order to stop the rotation of the wheel. The cradle a is mounted so as to be capable of being oscillated on a sleeve c surrounding the shaft d, and the side a<2> may be adjusted relatively to the side a' so that it may be positioned for winding the cord in cylindrical or in conical form. A lower extension o, Fig. 2, of the cradle a is provided with holes, to any one of which a chain attached to a weight p may be hooked. The weight causes the cord tube to be pressed against a roller l mounted in bearings in brackets m in order that the cord may be wound in compact form. The cord is laid on the tube by a guide n which is mounted upon a rod q. This rod is reciprocated in suitable guides by a grooved cam, which is driven at an adjustablespeed through cone pulleys and spur gearing from the driving- shaft. A plate u is mounted so as to be capable of oscillation on a shaft v carried by a bracket w, and carries an oscillatable box rprovided with a projecting finger r<2>. A lever y is mounted on a stud 2 carried by a projecting part 3 on the bracket w, and the downward movement of the lever y is limited by a projection y<2> coming against the part 3. When the lever y is lowered, a hook y' upon it engages the finger r<2> and holds the plate u in its normal position, and a rod 4 secured in ears on the plate n projects into a slot in the lever y. A lever z is capable of oscillation on the sleeve c, and its lower end is connected to a weight 1. A projection z<1> on the lever x rests upon the rod, thus maintaining the lever z in its normal position. Projections z<2>, z<3> on the lever z act upon a crossbar 5 forming part of the cradle a, the projection z<2> acting at times to bring the tube on the mandrel b against the roller l, and the projection z<3> to remove it from the roller. A lever 8, Fig. 3, is mounted on an axle 7 carried by the cradle a, and is provided with a fork engaging a groove in the chainwheel i. The lever 8 is acted upon by a spring 11 so that its horizontal arm bears against a fixed cam 10 on the sleeve c. When the machine is at rest. the cradle a is in such a position that the mandrel b is away from the roller l, and the lever y is in the position L. To start the machine, the lever y is lowered, causing the hook y' to engage the finger r<2> and the rod 4 to act upon the lever z. This lever is turned against the action of the weight 1, and the projection z<2> pushes the cradle a in the direction opposite to that of the arrow H to allow the cord tube to bear against the roller l. At the same time, the arm of the lever 8 on the cam 10 is moved to allow the spring 11 to act on the lever and move the chain-wheel i, causing the projection i<1> to engage the projection j<1> and the chain-wheel i and the mandrel b to be rotated. The oscillatable box r carried by the plate u is provided with detector-wires s which are supported by the cords passing through eyes at their upper ends If a cord breaks, the corresponding wire s falls and is engaged by a cam t, and the box r is oscillated, causing the finger r<2> to be disengaged from the hook y'. The weight 1 turns the lever z in the direction indicated by the arrow H, and the projection z<3> acting upon the bar 5 moves the cradle a and causes the lever 8 to be acted upon by the cam 10 to disengage the projection i<1> from the projection j<1>, and to bring the projection i<2> into engagement with the projection k, thus stopping the revolution of the mandrel b. The further action of the cam 10 moves the wheel i back a short distance so that the wheel and the mandrel are free to be turned by hand. An adjustable finger 13 is pivoted to the cross-bar 5, and its lower end 15 bears upon the plate u. As the yarn is wound upon the tube, the pressure of the roller l causes the cradle a to be moved in the direction of the arrow H, until, when the winding is completed, the end 16 of the finger 13 acts against the finger r<2> and disengages it from the hook y<1>, causing the mandrel to be stopped in the manner described. In order to stop the winding more rapidly, a movable cam may be used instead of the fixed cam 10. The cam is rotatable on the sleeve c and is connected by a connecting-rod to the plate u. The movement of the plate and the opposite movement of the cradle act together and cause a more rapid action of the lever 8. When two or more cords are being wound together, they pass from a guide 27 over a flannel-covered board 19 and over a movable rod 26 to the detectors s. The cords then pass upwards over a roller at the top of the machine, and over a roller 73 to the guide n. The rod 26 is carried by arms 25 on a shaft 24, to which is secured an arm 35 having a stud engaged by a groove in a cam 30. This cam is arranged to be oscillated by an arm 32 and an adjustable rod 33 connected to the extension o of the cradle a. When the winding is commenced, the rod 26 is in the position shown, so that the cords pass over the whole length of the plate 19. As the cord is wound and the cradle is moved away from the roller l, the cam 30 is turned gradually, and the rod 26 is moved towards the position N, thus causing the tension to be diminished gradually. When single cords are being wound, the board 19 is replaced by two plates 36, Fig. 6, which are provided with projections 37 entering holes 38 in the opposite plates. The projections enter the holes most deeply at the inner end. The cord passes between the plates and is deflected into a zig-zag course by the projections. The rod 26 is moved as before to diminish the tension. In another form of tension device, shown in Fig. 9, the cord passes between a pair of guides 53 round pins 42 projecting from a disc 41 provided with an axle carried by a frame 44. The frame is detachably mounted on a rail 23 by means of lugs 54 and pins 55. The disc 41 may be rotated through pinions and a spur-wheel by a rack 49, which is moved by means of a groove 58 in a cam 59. The cam is gradually turned in the manner described above by connection with the extension o of the cradle. When the mandrel is stopped, the disc is in such a position that the pins 42 are one on each side of the line between the guides 53, so that the cord may be readily placed between them. When the cradle is moved to commence the winding, the disc is rotated by the motion of the rack into the position shown, and as the winding proceeds the disc is gradually turned back to diminish the tension. The upper guide 53 is in front of the lower guide, so that the cord is inclined and one part does not rub against another. In a modified form of this tension device, three discs 41 provided with pins are employed, and are placed one above another. The discs are slightly rotated to cause the yarn to follow a zig-zag course. The cams for operating the rack 49 may be provided with a groove suitable for operating the rod 26 in the devices shown in Figs. 2 and 6, in order that any of the devices may be used as required.
