15 Claims.

This invention relates to winding machines and more particularly to an improved device for arresting the operation of the machine when the package being wound reaches a predetermined SIZE.

The present invention is particularly directed to winding machines of the type generally disclosed in United States Patent No. 801,941 to tional winding machine, it is to be understood that it is not limited to application thereto. In the description, the conventional parts'of the gitudinally of the core by.a thread guide that bears against the surface of the winding swings away from the spindle as the wound package increases in size. The form of device for stopping the winding machine generally employed with this type of winding machine and shown in the Wardwell patent has the disadvantages of being somewhat slow-acting and of increasing the pressure of the thread guide against -the surface of the winding asthe package-approaches the predetermined size to whichthe stopping device has been set.- The slow-acting characteristic of the device results in cones-of non-uniform weight but, what is more important, the increased pressure on the package during actuation of the stopping device deforms the cone.

It is an object of-the invention to provide a novel form of device for automatically stopping the winding when the package reaches a predetermined size which device avoids the exertion of undue pressure of the'guide against the package. Another object is to provide such a. device which is simple in character and which may be a readily attached to standard machines without a altering the structure thereof. Another object is to provide such a device which is'adapted to cooperate with the mechanism for stopping'the device automatically upon breakage or exhaustion of the supply of the yarn or strand being wound. A further object'is to provide a device which is adjustable in character so that a package of any desired size may be obtained upon the machine or machines to 'whic h'the attach- 7 present invention applied thereto,

Figure 2 is a side elevational view of the winding machine shown'in Figure 1.

While the invention will be. described hereincular type of'convenwinding machine will first be described and this will be followed by a description of the part which constitute the present invention.

Referring to the drawing, reference numeral 2 designates the fixed main frame of the machine. At the top of frame 2, a rotating spindle 3 1s journaled in suitable bearings and is adapted to be driven by means of a belt pulley or other suitable mechanism (not shown). The spindle is adapted to receive a cone or cop tube 4 upon which the package 5 is to be wound. v

A shaft 6 is journaled in the frame 2 and extends in a direction parallel to the winding spindle 3. This shaft 6 is connected to the spindle and is driven therefrom by suitable means, such as gears, a belt and pulleys, sprockets and chain (not shown). The shaft 6 also carries a helical grooved cam I for rotation therewith.

, A traverse frame 8 is pivotally mounted upon. the shaft 6 upon which it is suitably balanced a porcelain bail I] may be rotatably supported on a wire l2 whose depending legs adjacent the I control the operation of the spindle 3 and the ends of the bail are suitably fastened within recesses in the plate ID by means of set screws l3. The traverse frame 8 is constructed to provide a horizontal groove through which a traverse bar ll may reciprocate. A thread guide l5, whose upper end is adapted to press lightly against the package being wound is fastened toone endof the traverse bar l4 for reciprocation therewith.

ing back toward the spindle by means of a lever l8 having one end fastened thereto at I!) and the other end engaging within a groove formed underneath a segment 20 which is pivotally fastened to the main frame 2 at 2|.

The operation of the winding machine is controlled by a starting lever or handle 22-, mounted on one end of a rotatable rod 23, supported in bearings at the top of the main frame 2. The opposite end of the rod 23 carries means for operating a clutch or similar device (not shown) to other parts of the machine driven therefrom. A lever 24 is mounted adjacent the starting lever 22 on the rod 23 so that it rocks therewith. One end of lever is normally biassed in a counterclockwise direction by a spring 25 fastened to the frame 2 and is provided with a braking means 26 which is adapted to press against the spindle 3 and to stop the rotation thereof when the lever 22 is in the, stop position 'in which position the clutch or other device for operating the spindle 3 'is disengaged. The other end of the lever 24 is formed as a curved arm having a hook 21 at its end. -When the starting lever 22 is in operating position, in which the clutch is'engaged with the spindle 3 and the brake is lifted therefrom (as shown in Figure 1), the hook 21 engages another hook 23 secured to or constituting part of the pivoted segment. The machine may be maintained in running position'by setting these hooks 21 and28 in opposition to the spring V 25 which otherwise would tend to set the brake and to swing the starting lever 22 into the stop position.

In operation of the machine, the yarn passes 1 first through a tension device 29 over the guide 30, under a break or exhaustion detector 3|, over the porcelain bail H and through the traverse guide I! to the package. Thebreak detector 3| comprises a device pivotally mounted at 32 upon segment 20. The device is composed of two arms 33 and 34, one of which 33 extends toward a wheel 35 having-numerous prodections or ridges an 38 thereon mounted upon the cam shaft i for rotation thereby. The other arm 34 is bent to form a horizontal-extension 31 adapted'to ride upon the yarn and along which the yarn may be traversed to a certain extent. The extension 31 may be bent at the end to form a hook 38 to prevent the yarn from accidentally slipping out of engagement therewtih. The first arm 33 is of such length and the entire detector device 3| is so balanced that upon breakage of the yarn, the device swings in a clockwise direction to bring arm 33 into the path of the projections 36 upon the rotating wheel 35 which in turn forces the segment 20 in a counterclockwise direction willciently to release the two hooks 21 and 28 and thereby permit the spring 25 to throw the start-.

may be pivoted upon the same pivot 32 as the" end breakage detector 3| though this is not es- I sential. This arm 39 is provided with one projection 40 which is adapted-to serve as a resting stop to support the arm in an upright position upon the segment 20 at an angle slightly inclined from the vertical (as shown in Figure 1 which shows the machine as the package approaches full size). The amount of this angle is preferably as small as is consistent with the vibration inherent in the operation of the machine or associated with neighboring machines. The free end of the arm 3915 provided with a second pro-' jection H which is adapted to strike the arm ll of the end breakage detector 3! "when the upwardly extending arm 391s swung out of its resting position. The weight oicarm 39 may vary .widely,--being made heavier when operating with greater tension in the course of yarn approaching the package. I: desired, the-projection 4! may beithreaded to receive interchangeable intemallythreaded sleeves of various weights similar to the sleeve ll described hereinbelow.

This sizing stop" arm or impact member II is adapted to be operated upon engagement by any part of the traverse frame 8. Preferably, the part whichengages the stop arm 39 is readily adjustable. For example, an L-shaped member 42 may have one leg 43 provided with threads adapting it .to receive an internally threaded sleeve I4 and a lock nut 45 to lock it in any desired position along the length of the threaded leg 43. This Lshaped member may be fastened to any part of the traverse frame 8. As shown in the drawing, it is fastened to the frame 3 by means of one of theset screws employed in holding the when for the porcelain bail ll.

Besides the adjustment that is possible by merely screwing the sleeve 44 to a different posi- 2 tion, an adjustment may be accomplished in exlt-reme cases by replacing the sleeve itself with a sleeve of longeror shorter length.

The operation of the sizing device is readily apparent from the preceding description and invalves the swinging of the upright stop'arm 3.

through the slight angl e fromthe vertical to. throw it outof balance upon which the stop arm of its own weight strikes and swings the end breakage detector device 3| with its arm 23 into n the path of the rotating wheel which in turn causes the liftingof the segment 20 and disengagement of the hooks 21 and 28 with the consequent stopping of the machine. All that is required to set the sizing device upon starting the 5 machine anew is to' swing the stop arm-.39 into its upright position with the projection resting upon the segment 20.

- From the description of the device of the invention, it is apparent that it is quick in action and involves only a slight amount of pressure for a relatively shorttlme. during the last part of the winding. It is simple in character, readily attachable to any winding machine and is easily adjusted.

In-the present specification and claims, the term package is used inageneral sense to indicate any form of wound .mass' and the term yarn" is intended to designate any kind of strand material whether textile or otherwise.

While a preferred embodiment of the invention has been disclosed, it is to be understood that changes and variations may be made without departing from the spirit and the scope of the invention as'defined by the appended claims.
