WINDING-MACHINE.

Specification of Letters Patent.

Patented Oct. 19, 1909.

To all whom it may concern:

Be it known that I, SIMON W. l/VARDWELL, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Wind- -Machines, of which the following is a My invention consists particularly of de-' vlces for use with the traverse-regulating mechanism of a winding machine similar to that disclosed in my pending application, Serial No. 31,700, filed September 45th, 1908.

The accompanying drawings illustrate, respectively:Figure 1, a front elevation of the traverse regulating mechanism of the machine; Fig. 2, an end elevation of the same, showing the relation of the new device thereto; Figs. 3, 1 and 5, details of the arrangement and mode of operation of the parts. I

Referring to Figs. 1 and 2, 5 is the traverse cam of the winding machine, which, through suitable connections, imparts reciprocation to the yarn-depositing guide, not here shown, that lays the yarn on its holder. The means for connecting the cam 5 with the traverse-rod which carries the yarn-guide are identical with those described in my pending application above referred to and consist, in brief, of the following elements:

A lever 12, pivoted on the stud 11, carries at the extremity of its lower arm a roll 13 which engages the groove 6 of the cam 5. The upper arm of the lever 12 is curved and formed with an arcal slot 14 with rack-teeth 15 on one side. Fitted to the slot 14 and adapted to engage the teeth 15 is a pinion 20, rotatively secured to the end of a connecting-rod 19 which is fastened at its opposite end to the traverse-rod, not here shown.

The pinion 20 carries a ratchet wheel 23, which, through suitable instrumentalities, is caused to turn to travel the pinion 20 on the teeth 15 and vary the connecting-rods point of connection with the lever 12. The instrumentalities for turning the wheel 23 consist of a pawl 22 carrying a finger 21 which engages the teeth of the wheel intermittently,

each time the lever 12 is oscillated by the cam 5 to carry its upper arm to the right, as shown in Fig. 1. As the pinion 20 travels up on the lever 12, Fig. 1, showing it inits upper position on the arm of the lever, the pawl 22 is swung upward on its pivot 24; to cause the finger 21 to follow the wheel 23 to keep it in position to engage the teeth of the ratchet at each oscillation of the lever 12.

The movement of the pawl 22 is elfected through means controlled by the growing diameter of the yarn mass as the layers are built up on the tube or holder which serves as a central support or core for the bobbin. These means consist of a lever A which carries at one end the contact wheel 25, constituting an antifriction part'of the lever itself and adapted to initially bear on the surface of the tube or holder which is represented by the dot-anddash circle a, Fig. 2, and to be moved outward by the growing'diameter of the winding. The broken lines show the wheel and lever A at the start of the winding and the full lines represent their position when the base of the bobbin has attained its full diameter, represented by the dot-anddash circle Z2.

Fulcrumed on the stud 24, the pivot of the pawl 22, is a lever 43 formed with a quadrant as on which is an adjustable stop or detent 53, see Fig. 1. Pivoted on the pawl 22 is a latch 57 with its end 58 formed with a shoulder 59 adapted to engage the detent 53. The latch 57 when engaged with the detent 59 connects the pawl 22 with the lever 13 so that when the latter is swung upward on its pivot it raises the pawl 22 to cause the finger 21 to follow the wheel 23 as the latter travels upward on the lever 12. hen the pawl 22 has been moved to its predetermined upward limit, a suitably adjusted pin 61 supported in the frame of the apparatus engages a trigger arm of the latch 57 to free the detent 59 from the detent 53, as shown in Fig. 1, and the pawl 22 is then returned by gravity to its lowermost position. This action takes place when the base of the bobbin has been built up to the required diameter and relieves the wheel 23 from further engagement by the finger 21, so that the action of the lever 12 thereafter remains constant and further traverse of the yarn guide is effected with a uniform extent. v

The lever 43 is moved by the lever A through a connection or link 34 which has its ends formed to receive the balls 30 and 32 carried on said levers. The lever 43 is formed with a counterweight 44, the gravity of which tends to resist the downward movement of the wheel 25, and further serves to return the wheel 25 to its initial position at the completion of the winding as hereinafter more fully described.

It will be evident from the above descrip tion, and from reference to my pending application before referred to, that the operation of these devices is to cause the traverse guide to reciprocate'with a gradually increasing extent of traverse as the layers of yarn are deposited on the holder, so that a foundation cone is formed, upon which, subsequent layers of uniform traverse are deposited with the guide advancing along the length of the bobbin. It will also be understood that after the foundation cone is formed, the bobbin increases by longitudinal extension only, with the winding being done on the tapered surface of the cone so that the resultant package has a substantially fiat base, a cylindrical body, and a tapered nose from which the yarn is delivered in unwind- 1n The novel features of the present invention consist of means for controlling the position of the wheel 25 so that after the base of the bobbin reaches its predetermined diameter the wheel is automatically removed from further contact with the yarn mass. The present invention also includes devices for automatically returning the wheel to its initial position to wind a new bobbin after the finished bobbin is removed from the holder on the winding spindle and a new tube applied thereto.

The automatic control of the wheel 25 is effected through means connected with and operated by the starting handle 97 of the machine. The handle 97 is mounted on a rod 63 which serves as a rocker-shaft to operate the clutch devices of the machine, not here shown as they may be of any suitable arrangement as usually provided in winding' machines. The handle 97 normally stands in a vertical position when the machine is inoperative and is rocked in the direction indicated by the arrow 0 in Fig. 2, to the position here illustrated, to start the machine. Suitable detents are provided to retain the handle in this position during the winding and upon the release of the detents a spring or equivalent device returns the handle to its vertical position and rocks the rod 63'to stop the machine. These parts are not shown as they are well known in connection with their use on this class of machines and do not form essential elements of the present invention.

The handle 97 is mounted on the rod 63 by means of a collar 64 secured to the rod and formed with two lugs 65G5 between which the handle is held by a pin 66. The pin 66 serves as a pivot, allowing the handle to be rocked independently of the rod 63 in a plane at right angles to its movement when rocking the rod. For convenience in describing the operation of the starting handle the movement of the latter in the direction of the arrow 0, Fig. 2, will hereafter be referred to, as to the right; movement in the opposite direction, as to the left; in Fig. 3, movement in the direction of the arrow cl, as backward; and in the opposite direction, as forward. The two last named movements are designed to operate the holder or mandrel 88 which secures the bobbin tube 87 011 the spindle 3, Fig. 3.

As described in my pending application, Serial No. 451,700, filed September 4th, 1908, the holder 88 is of slightly tapered form with its larger end hollow and split longitudinally to form expansible segments 88 grooved at 90 to form teeth 90 on the outer surface. The end of the holder is formed with a head 91 having a cylindrical bore 92 with a bevel 93 at the inner end thereof. A sleeve 94, slidable on the spindle 3, has a circular flange 95 with a beveled edge 96 to engage the bevel 93 and open the bore of the head to admit the flange 95. The sleeve 94 is shiftable on the spindle 3 by means of the handle 97 which. has a toe 98 extending between the two fianges 99 and 100, see Figs. 3 and 4. Movement of the handle 97 backward in the direction indicated by arrow (Z, Fig. 3, slides the sleeve 94 outward on the spindle to release the segments 88 and allow them to contract so that the tube 87 may be forced snugly on to the holder. After the tube is in position, the handle 97 is pulled forward to slide the sleeve 94 backward on the spindle to expand the segments and engage the teeth 90 with the inner surface of the tube to hold it firmly in position for the winding.

Operated from the toe 98 of the handle 97 is the controlling device for the contact wheel 25. This consists of a member hinged to a portion of the frame 71 of the machine by the pin 72 which extends through two ears 73 and 74 on the member 70,see Fig. 2. Dependent from the main portion of the member 70 is a curved arm which is located adjacent the arm 26 of the lever A and adapted to bear against the right angled projection 26 on said lever, see Fig. 3. Near the end of the arm 75 is a beveled projection 76, so located that when the projection 26 rides over it, it will carry the wheel 25 away from contact with the base of the bobbin as hereafter more fully explained.

Pivoted at 77 on the member 70 is a lever 7 8 which is formed at its end with a hooked arm 79 bent at right angles at to adapt it to be engaged by the toe 98 of the lever 97.

The lever 78 also has an car 81 bent at right angles to the main portion and adapted to rest on the rim of the flange 99. Extending upward from the main portion, the member 70 has an arm 82 which is bent at right angles at its end to form a stop 83 to limit the inward movement of the lever 78. The lever 78 is normally forced against the stop 83 by a spring 84 which bears against the edge of the lever and is coiled around the pivot 77. The spring 84 then extends to the hinge of the member 70, being coiled around the pin 72 with its end 85 hearing against the frame 71 so that it tends to swing the member 70 against the lever A to provide a yielding friction on the latter. The friction of the member 70 onthe lever A has a steadying effect upon the latter so that the wheel 25, in riding on the yarn mass, should the surface of the winding become slightly uneven, will be prevented from vibrating or chattering. A smooth, even movement of the wheel outward from the tube is thus provided for. Further, the action of the spring 84 on the member 7 0 tends to force the projection 26 on the lever A down the incline of the beveled projection 76, after it has been carried over the rise of the projection by the effect of the winding bearing on the wheel 25, so that the wheel is moved away from further contact with the bobbin after the base of the latter has reached the predetermined diameter. By releasing the member 70 from engagement with the lever A, the latter is allowed to swing upward to its initial position to bring the wheel 25 against the tube to start the winding of a new bobbin. This release is eifected by the movement of the sleeve 94 when the latter is slid back on the spindle to expand the tube holder to engage the tube.

The operation of the whole mechanism will now be fully explained :Assuming that a bobbin has been completed on the ma- 1 chine, then the parts will be in the position illustrated by Figs. 1, 2 and 3, excepting the pawl 22 which will be returned to its initial, lowermost position through gravity, upon the release of the latch 57, as before described. The lever A will be in the position shown by full lines in Fig. 2, held by the engagement of the beveled projection 76 with the arm 26 of the lever, as shown particularly in the plan view, Fig. 4. The sleeve 94 is in its rearward position with the flange 95 engaging the bore 92 to hold the segments of the tube 88 expanded and gripping the tube 87. The handle 97 is in the position shown in Fig. 2 while the machine is winding, with the toe 98 engaging the end 80 of the lever 78 to keep the ear 81 just clear from contact with the rim of the flange 99. This prevents frictional wear between the ear and the flange while the latter is rotating with the winding spindle; but when the machine stops, the handle 97 is returned to its vertical position and the toe 98 releases the lever 78 and allows the ear 81 to bear on the rim of the flange. The flange 99 is represented by a broken line in Fig. 2, as it woiiild obscure the other parts to show it in ful To release the teeth of the holder from the tube 87, to allow the dofling of the completed bobbin, the handle 97 is pressed back in the direction indicated by the arrow d, Fig. 3. This movement of the handle slides the sleeve 94 outward on the spindle 3, carrying the flange 99 out from under the car 81 and allowing the lever 78 to be moved inward under influence of the spring 84. The lever 78 moves inward against the stop 83 with the ear 81 back of the flange 99, as shown by broken lines, Fig. 2. After the full bobbin is removed and a new tube placed on the holder, the handle 97 is pulled forward to slide the sleeve 94 backward to expand the segments of the holder. As the sleeve 94 slides backward, the rear face of the flange 99 engages the ear 81, see plan view, Fig. 5, and moves the lever 78 bodily to swing the member and carry the arm away from the lever A. This frees the beveled projection 76 from the projection 26 and the lever A is moved upward, under the influence of the counterweight 44 on the connected lever 43, until the wheel 25 bears on the surface of the tube 87, as represented by dash lines, Fig. 2. It is now necessary to move the lever 78 to remove its ear 81 from behind the flange 99 so that the member 70 may again be swung outward on its pivot 72 with the arm 75 bearing against the lever A. This is accomplished by the movement of the handle 97 to the right, Fig. 2, to start the machine, the toe 98 engaging the end 80 of the lever 78 and moving the latter outward until the ear 81 is free to spring back over the rim of the flange 99. As before explained, the toe 98 remains in contact with the lever 78 to keep the ear 81 free from the flange 99 during the winding.

As the machine continues to operate, the yarn is built up on the base of the holder and as each layer is added the wheel 25 moves outward to regulate the traverse of the yarn guide, all as previously explained. As the lever A moves downward on the arm 75 the projection 26 finally encounters the bevel 76, rides up over the latter, and the pressure of the spring 84 causes the bevel to act as a wedge to force the lever A still farther downward and remove the wheel 25 from contact with the winding. The pin 61, Fig. 1, is so adjusted that at this point the latch 57 is released from engagement with the lever 43 and the pawl 22 drops back to its lowermost position. This prevents further engagement of the wheel 23 so that the traverse of the guide thereafter remains constant and the bobbin grows by longitudinal extension, without any further increase in diameter. It will be understood that the longitudinal growth of the bobbin is efiected through the means of a progression Wheel, not here shown, but described in my pend ing application before referred to, which contacts with the surface of the winding and feeds the guide along its traverse rod.

After the bobbin is completed by the addition of layers wound on the conical sur face of the heel or base, it is removed by manipulation of the handle 97, as first explained. The wheel 23 is next turned back to its lowermost position on the lever 12. The handle 97 is then pressed backward to secure the new tube on the holder and after the yarn is led through the guide with its end secured to the holder the machine is started by rocking the handle to the right, Fig. 2. It will now be understood that the simple manipulation of the starting handle serves to return the wheel 25 to its initial position and upon the return of the wheel the latch 57 engages the lever 43 so that when the wheel 25 moves outward again, under influence of the winding, it regulates the position of the pawl 22 which, in turn, acts on the wheel 23 to control the traverse of the yarn guide.

The parts are automatically controlled by the shifting of the starting handle so that the operator is relieved of all care in setting them to secure their proper adjustment and coaction.

I do not herein claim the mechanisms previously shown and described in my pending applications, Serial Nos. 541,700 and 541,701, filed September 1th, 1908, by themselves, but only in combination with the new and improved devices now disclosed.
