' 2 claims. (01. l q-9.5)

My invention relates to new and useful improvements in textile machlnes and more particularly to spinning, doubling and twisting machines. e e

One of the principal objects of my invention is to provide a spinner whereon the cop or package is maintained in a stationary condition and the thread or the like delivered therefrom by the rotation of the spindle, thereby delivering two turns of twist for each rotation of the spindle.

Another object of my invention is to provide a device of the above described character wherein the package or cop is prevented from rotation with the spindle by or through the action of a magnetic force. g A further object ofmy invention is to provide a device of the above described character wherein the magnetic elements utilized for preventing rotation of the package also serve to counteract or ease the vertical thrust on the spindle by the package, thus minimizing the amount of power required inthe operation. a A still further object of my invention is to provide a device of theabove described character capable of being secured to spinners, already in use and which is easy in attachment, simple in construction, durable in use, efllcient in operation and economical in manufacture.

from the following description, appended claims and annexed drawings. r

Referring to the drawings wherein like reference characters designate like parts throughout Fig. 1 is a front elevation of my invention. Fig. 2 is a top planview thereof. Fig. 3 is a sectional view taken on the line 3-3 of Figure 1, the samebeing illustrated as mounted on a section of a bolster rail.

In practicing my invention, with reference to the preferred embodiment shown in Figures 1 to 4 inclusive of the drawings, there is illustrated a section of r a bolster rail 5 of ordinary construc: tion, the. same constituting a part of a textile Other objects and advantages will be apparent Fig. 6 is a side elevation, partly in section, of r the modified form illustrated in Figure 5.

machine (not shown), for instance a spinning, doubling and twisting machine. Threadedly secured on the rail 5 is a vertically extending spindle bolster 6 through the upper end of which is rotatably mounted the lower end of a spindle I having fixed thereon a spindle whirl 8 for receiving the conventional belt whereby the spindle is rotated relative to the bolster and bolster rail. Intermediate of the ends thereof, the bolster 6 is fashioned with a circumferentially extending flange 9. Subjacent said flange said bolster is threadedly secured to an arm ill of a magnet support ll of nonferrous metal. The body of said magnet support is formed with a chamber H, the bottom of which is centrally apertured as at l3 whereby the spindle including the whirl 8 may be removed therethrough. The upper end of the spindle has secured thereto a ball bearing assembly I 4 effecting a bearing connection with a bearing sleeve I5 formed on the lower face of a cylindrical shaped package support l6 whereby to efiect a free rotation of the spindle relative to said support. A collar ll embraces in spaced relation the'sleeve l5 and is secured to the spindie 1 subjacent said bearingassembly to form an oil reservoir in which the bearing assembly rotates. within said reservoir to form a continuous bath for the relative moving parts.

A suitable oilcrother liquid is provided posed permanent magnets l9 secured on the upl per face of the magnet support on each side of the package support. Said magnets are arranged in relation to the ring l8 in a manner whereby the magnetic force serves to counteract the vertical thrust on the spindle by urging the ring l8 upwardly to the position illustrated in Figure 3. Mounted on the upper surface of the package support is a package or cop 20 of ordinary construction and formed witha longitudinallyem tending bore 2|. Said bore isof a larger diameter than the outside diameter of theupper end of the spindle 1 extending therein to permit free rotation of the spindle relativeto the package and package support. Inserted downwardly into the bore 2| is a hollow thread tube 22, the same being of a sufficient outside diameter to effect a snug flt with the wall of the bore M to prevent relative rotation therewith. The upper end of the threadtube extends beyond the top of the package and is fashioned with a flange 22 enusin said top and forming a bearing surface for a tension flyer 24 freely rotatable on the upper end of the thread tube. The tension flyer is formed with a laterally extending arm terminating at the outer end thereof in an eye which receives therethrough a delivery length of a thread T.

Secured to the lower end of the collar I! are a pair of oppositely disposed arms 25 constituting the spinning flyer. Said arms are fashioned on the outer ends thereof with eyes to receive the thread T. Subjacent the lower end of the collar II, the spindle I is fashioned with a pair of oppositely disposed ports 26 communicating with a vertically extending thread passage 21.

Upper and lower spinning rings 28 surround the package support and are connected to the upper and lower faces of the magnets I9 respectively. The inner peripheries of the rings 29 extend slightly beyond the pole faces of the magnets to prevent the thread T engaging said pole faces. As illustrated in Figure 4 a shuttle hook comprising a handle 30 having a flexible elongated tool 3i terminating in' a hook section 32 is provided for threading the device as hereinafter set forth.

In operation, withreference to the structure illustrated in Figures 1 to 4 inclusive, a package containing a full supply of thread is positioned upon the package support It, the upper end of the spindle I extending a distance within the bore 2|. The lower end of the thread tube 22 is inserted within the bore of the package and the tension flyer 24 positioned about the upper end of the thread tube. In this position of the parts the hook section 32 of the shuttle hook is inserted through one of the thread ports 29, upwardly through the thread passage 21 and through the bore of the thread tube 22. The end of the delivery thread T is passed through the eye in the tension flyer 24 and secured to the hook section 32, and'the shuttle hook withdrawn. Upon withdrawal of the shuttle hook, theend of the thread is passed through an eye in one of the arms of the spinning flyer 25 and upwardly between the package support including thering it and the magnet l9 including the spinning rings 28. The end-is then drawn upwardly for attachment to another package through appropriate rollers and the like. Upon completion of the threading of the device, as heretofore described, power is supplied through the medium of a belt engaging the spinning whirl I. Thus the spindle is rotated while the package and package support are maintained in a stationary position due to the coaction of the magnets l9 and the ring I8. Rotation of the spindle causes the spinning fiyer to likewise rotate, thereby imparting a double twist to the thread for each revolution of the spindle. As this action takes place, the thread is drawn downwardly through the thread'tube causing the tension flyer to rotate about the tube during the unwindingof the thread from the package.

When the thread from a package has become exhaustedit is only necessary to remove the thread tube including the tension flyer, empty package and position a filled package with the thread tube and tension flyer connected thereto on the support.

In the modifiedform illustrated in Figures and 6, the ferromagnetic ring 35 extends across thebottom of the package support and is centrally apertured as at 35 for receiving therethrough the spindle and collar illustrated in Figure 3. In this instance, the support 21 has secured to the upper face thereof a ring holder 38 for maintaining a spinning ring 39 in position about the package support, said ring having oifset ends 40 whereby the thread may be inserted between said ends within the support 21. Electro-inagnets ll are attached to the vertically extending sections 42 of the support 31, and through the medium of the ring 39 form a magnet circuit entirely surrounding the ring 35 thus increasing the area of the magnetic field.

In the modified form illustrated in Figures 7 and 8, the package support 50 is mounted over the spindle in the same manner as the form illustrated in Figures 5 and 6 and a plurality of packages are positioned on said support and held thereon by means of vertically extending shafts 5!, each having rotatably mounted tension flyers 52. The lower end of a thread tube 53 is secured to the package support 5| and the upper end has secured thereon a thread cradle 54 having a plurality of outwardly. extending arms, one for each package. The arms are fashioned with thread supports 55 over which the threads T are trained and extend downwardly through the thread tube 53. Said threads extend through the spindle in the same manner as in the instance of Figure 3 and are trained upwardly about the outer periphery of the package support. Laterally extending from the upper section of the thread tube are a plurality of drop wire supports 56 for guiding and supporting a plurality of drop wires 51, each of said wires are fashioned at the upper end thereof with a hook section 58 for engagement over a thread T and the lower end pivotally connected to one end of a bell crank lever 59 pivotally mounted within the support 50. The other end of the bell crank lever is pivotally connected to an arm 59 having an outer end extending within an aperture in the side of the support 50. The outer ends of the arm 60 are each fashioned with cutting edges iii and are maintained, during the normal operation of the device, in retracted position relative to the outer periphery of the support 55. From the foregoing it will be apparent that as the thread is drawn downwardly through the thread tube 53 each of the tension flyers 52 will be rotated due to the unwinding of the thread about the package in the same manner as in the instance of the single package illustrated in the preferred embodiment. During the operation should one of the threads T break, the respective drop wire supports suspended thereon will of a consequence drop downwardly and actuate the bell crank lever 59. This actuation of the bell crank lever 59 serves to project the respective arm 50 into the path of the threads adjacent the side of the package support and sever the same. This severance of the thread serves to operate a stop mechanism on the machine for preventing further rotation of the spindle until such time as the device is rethreaded for operation.
