6 Claims.

This invention relates to winding machines and particularly to a spool or bobbin supporting and rotating mechanism adapted to automatically disengage the spool or bobbin from 5 its driving wheel when the yarn being wound on the spool breaks and also when the spool is filled to a predetermined diameter or whenever desired to have the winding stopped by the operator for any reason.

10 An object of the present invention is to improve a device for rotatably supporting a spool or bobbin being wound with yarn so that its rotation may readily be stopped when filled with yarn or when the yarn being wound breaks or runs out or manually whenever the operator desires to stop the rotation of the spool.

A feature of importance whereby the above named objects are obtained is that a spring actuated member, normally retained during operation in a retracted position, when released by breakage of the yarn or filling of the spool with yarn to a predetermined diameterwill engage and elevate a cradle in which the spool is supported.

And finally it is an object of the invention to provide a member hinged to the spring actuated member and normally engaging a catch on an extended lever so that when this hinged member is swung laterally or when the lever is moved about its pivot the hinged member will disengage the spring actuated member from its latch and permit this latter member to swing upward about a horizontal axis and raise the spool sup- 35 porting cradle or yoke so that the spool will be disengaged from the rotating wheel.

With the above and other objects in view, my invention includes the feature of construction and operation set forth in the following specifi- 40 cation and illustrated in the accompanying drawing.

In the accompanying drawing annexed hereto and forming. a part of this specification, I

45 have shown my invention embodied in a textile winding machine for spools or bobbins having a single end wound thereon, but it will be understood that the invention can be otherwise embodied and that the drawing is not to be 50 construed as defining or limiting the scope of the invention, the claims appended to this specification being relied upon for that purpose.

In the drawing: Fig. lis a complete plan view of the spool 55 supporting and lifting device.

Fig. 2 is a side view of the device taken from the right hand side of Fig. 1.

Fig. 3 is a similar side view taken from the left hand side of Fig. 1.

Fig. 4 is a transverse sectional view taken 5 upon the plane of line 44 of Fig. 1, showing a spool mounted in the support and in contact with its driving roll or wheel,

Fig. 5 is a perspective view of one of the members of the supporting means looking forward from its axis of oscillation and Fig. 6 is a fragmentary horizontal sectional view.

In the above mentioned drawing, I have shown but one embodiment of the invention which is now deemed preferable, but it is to be understood that changes and modifications may be made within the scope of the appended claims without departing from the spirit of the invention.

Briefly, and in its preferred aspect, my invention may include the following principal parts; first a supporting bracket adapted to be clamped or otherwise secured." to longitudinally extending members of a textile machine; secend a spool supporting frame or cradle pivoted to the support for free swinging movement about a horizontal axis parallel to the length of the machine; third a spring actuated member connected to the spool cradle, fourth a hinged portion of the last mentioned member movable about an axis normal to the axis about which the cradle and spring actuated member oscillate, this hinged portion having a projection extending below the cradle; fifth a forwardly extended lever normally engaging the hinged portion of the spring actuated member during the winding operation and adapted when moved laterally to release the spring actuated member for swinging movement upward, which movement also raises the spool supporting cradle; sixth an abutment on the cradle adapted when the spool is filled to engage and move the. hinged portion to disengage the spring actuated member and permit swinging movement thereof and of the cradle; and seventh means on said hinged portion to reset the spring actuated member, the hinged portion having an extension also to prevent swinging movement of the forwardly extending lever when the cradle is raised to its upper and inoperative position.

Referring more in a particular to thefigures of the drawing, I provide a supporting bracket H] for a spool cradle or support ll pivoted thereto for movement about a horizontal axis extending longitudinally of the machine. Preferably and as shown in the drawing, the bracket I may be secured directly to horizontally extending supports I2 on the machine of usual or standard construction. In order to pivotally connect the bracket I8 and cradle II there is provided a shaft I3 extending through suitable aligned holes provided in these members. The cradle or supporting yoke II for the spool I4 may therefore swing upward or downward relative to the supporting bracket I8, the spool I4 being guided therein while resting upon and being rotated by a driving or friction wheel I5 directly below the spool. Slots I6 within the extended portion on' opposite sides of the cradle II engage studs extending from opposite ends of the spool. With the cradle II in its lower position the spool I4 may rest with the yarn being wound directly upon the driving wheel I5. When the cradle II is raised by means presently to be described the spool M will be elevated out of contact with its driving wheel I5 and therefore the rotation of the spool Will stop.

On one end of the shaft I3 pivotally connecting the cradle II and supporting bracket I8 is rigidly secured a member I! to which is hinged a member, I8 having a laterally extending portion I9 engaging under an extended part of the cradle II. The hinged member I8 swings about a vertical axis normal to and intersecting the axis about which the cradle II moves. Normally the member I! keyed or secured to the shaft I3 is spring pressed in a direction to force the hinged portion or member I8 and its extension I9 engaging below the cradle II so that when the spring is released, the parts will be moved upward. This in turn forces the cradle II upward when the hinged member I8 is released. To effect this spring action a helical spring 28 may be wrapped around the shaft I3, one end of which is suitably attached to the supporting bracket I8 and the opposite end of which is attached to the shaft I3. The torsion of the spring 28'is in a direction to move the hinged member I8, the member IT and the cradle II upward.

On the hinged member I8: is a lateral extension or offset 2| adapted in one position of the hinged member I8 to engage under a horizontally and forwardly extending lever 22. The lever 22 is shown in full lines in Fig. 1 in its extreme right hand position. Spring 32 between lever 22 and the supporting bracket I8 normally holds lever 22 in this limited position, there being an abutment 39 on lever 22 engaging against the front of member ID preventing further movement of lever 22 byspring 32 beyond the limit position shown in Fig. 1. When in latched position with the lever 22 the hinged member I8 is in its lower position holding the spring pressed member I! down and permitting the cradle II to drop to its lowest position. To unlatch the hinged member I8 and permit this member to swing upward and raise the spool cradle I I, it is only necessary to move the hinged member I8 about its vertical axis toward the right or to move the lever 22 to the left about its axis which is also vertical. Preferably and as shown in the drawing the: lever 22 is attached rigidly at the lower end ofa short shaft 23 extending vertically and supported within suitably spaced holes in the supporting bracket III. A spring 24 extending between the hinged member I8 and the supporting bracket Ill normally forces the member I8 toward its position to engage the abutment 2| and hold the member I8 in latched position with the lever 22.

Below the abutment 2|, the member I8 is continued downward as indicated at 25 in Figs. 2, 3 and 4, this surface serving to bear against the 5 lever 22 when member I8 has been released and v has swung upward. With the lever 22 in contact with this surface 25 the lever is held in its extreme left-hand position and is not therefore oscillated back and forth as the lever 22 is engaged by the traverse rod 35 with which the machine is provided. The upper end of the hinged member I8 is provided with a finger pressing portion 26 at an oblique angle adapted to facilitate depressing and laterally swinging the member IB by the operator. By pressing upon the portion 28 the inclination of the end portion 26 is such that the hinged member naturally swings laterally as it is forced downward to again engage the hinged member I8 with the lever 22 and retain them in interlocked position. With these parts again latched winding continues.

In order to stop rotation of the spool or bobbin when filled with yarn or thread means are provided for swinging the hinged member I8 in a direction to unlatch the spring pressed member I1 and lift the supporting cradle I I and thus raise the spool from its driving wheel I5. For

this purpose a short upwardly extending pro 30 justed position by means of a nut on the screw and bearing against the projection 28. The rearward end of the screw 29 is adjacent a lateral projection 3! of the hinged member I8. As the diameter of the wound yarn on the spool I4 increases and the cradle II rises the screw 29 contacts with the projecting BI and moves the member I3 to unlatch the projection 2i on the hinged member I8 from the lever or arm 22. The supporting cradle II then is moved upward by spring 28 to disengage the spool from its driving wheel I5. By adjusting the position of the screw 29 the amount of yarn or thread wound upon the spool I4 before being disengaged from its driving means I5 may be widely varied.

In operation the supporting cradle II is permitted to swing freely so that the spool I4 may rest by gravity upon its driving wheel I5. During the winding operation the material being wound is guided by'the usual grooved porcelain roll 36 mounted on the traverse bar 35 reciprocated back and forth to wind the yarn evenly the entire length of the spool. Should the thread being wound break or run out the arm 31 on which the guide roll is carried would move to a position intercepting the lever or arm 22 and thus swing this member from the position shown in full lines to the position shown in dot and dash lines. (See Fig. 1.) This movement of the lever 22 would disengage the hinged member l8 by the arm 22 riding off the abutment 2|. The member I8 and the member I! would therefore be released and would be moved upwardly by the spring I3. This movement due to the lateral projection I9 on the member I8 will cause the support II to be raised and thus stop further rotation of the spool. Preferably and as shown in Figs. 2, 3 and 4, a light spring 32 normally holds the lever 22 toward its latching position with member I8.

Any form of guide for the yarn being wound may be provided, the one shown being of standard or usual form. Preferably and as indicated in the drawing, the traverse bar 35 is supported for longitudinal reciprocation upon suitable mounted rollers 38. These supporting rollers are mounted at the forward ends of brackets 39 which in turn are secured to the longitudinal members 12 on which the supporting members H! for the cradles H are fixed. As rollers 38 are provided both above and below the bar 35 the bar is retained in proper position but is free to move axially. In operation of the winding machine the bar 35 is slowly reciprocated a proper distance back and forth for the width of spools being wound. Means for this purpose are not shown as they form no part of the present invention. To mount the arms 31 carrying the yarn guiding members 36 holders 4| may be suitably clamped to the rod 35. The arms 3! have a depending extension of sufficient weight to hold the arms 31, when no yarn is passing over the guides 36, in position to strike against. and oscillate the arm or lever 22 to release member l8 and raise cradle H. With yarn being wound, however, the tension is suflicient to retain the arms 3? in a position avoiding contact with the lever 22 and preventing release and upward movement of member I 8 and cradle H.
