1 PIRN-BOBBIN-WINDING Application filed Kay 15, 1926. Serial No. 109,898.

My invention relates to a pirn bobbin winding machine of ring or clrcular form.

The object of the present invention is to improve and simplify the construction and z-irrangement of winding machines of this type to thereby increase the winding power whilst decreasing the floor space per spindle required for installing the machine.

I arrange a plurality of bobbins around and in contact with the periphery of a rotating friction disc, each bobbin spindle being supported at the'upper end by an upper ring frame and at the lower end by a lower ring frame, and all bobbins are simultaneously rotated by the rotation of the friction disc, so as to effect the winding operation by feeding the yarn passing through a guide hook fixed to a traversing ring frame, which ring frame is arranged between the upper and lower supporting ring frame and which is raised and lowered being driven from the vertical shaft of the rotating friction disc. Each bobbin spindle is arranged in such a manner that it is automatically lifted slowly during the winding operation and is finally withdrawn from the lower supporting ring frame upon the completion of the Winding operation.

In the accompanying drawings in which have illustrated my invention, Fig. 1 is a vertical sectional elevation of the Winding machine embodying the invention, 5 Fig. 2 a plan thereof one-half of the upper structure being omitted to show the driving gear.

Fig. 3 an enlarged detail view showing one of the bobbins and a part of the rotating friction disc, and

Fig. 4 a view seen from left of Figure 3,

Figs. 5, 6 and 7 are enlarged sectional elevation, plan, and cross section, respectively, of one of the bearing blocks mounted 0n the lower supporting ring frame.

On the standard 1 is mounted a lower supporting ring frame 2. J ournaled in the supporting arm of the ring frame 2 at the center thereof is a vertical shaft 3 which is conveniently supported in the thrust bearing 3 shown in Fig. 1. The shaft 3 is pro vided with fixed and loose pulleys 4 near its lower end and is connected to a. suitable source of power. To the up er end of the shaft 3 is secured a friction isc 5 which is formed with a conical flange 6, which as 'ing operation. spindle 12 is held slightly inclined toward shown in cross section has a curved outer surface.

To the horizontal annular flange 7 of the ring frame 2 are secured upright brackets 8 which carry at their upper ends an upper supporting ring frame 9.- Radial arms 10 are secured to this frame 9, each being provided with a bearing hole 11 for receiving the upper end of a bobbin spindle 12. The

lower end of the spindle 12 is slidably mounted in the horizontal flange 7 of the lower ring frame 2 extending through a central bore in the bearing block 13 mounted on said flange 7. The bobbin 14 mounted on the spindle 1.2 is held in frictionally contact with the circumference 6 of the friction disc 5, whereby a winding motion is imparted to the bobbin. A plurality of bobbins are arranged around and in contact with the disc- 5, and all bobbins are revolved simultaneously by the rotation of said disc, whereby the yarn winding operation is effected. A means is provided for lifting the bobbins slowly at a constant rate during the winding operation. Another means is provided whereby the bobbin is automatically disengaged from the friction disc 5 when the lower end of the spindle 12 is lifted and withdrawn from the bore in the bearing block 13 upon the completion of the wind- For these purposes, the

the direction of rotation of the disc 5, which is indicated by the arrow shown in Figure 4, so that the bobbin 14 may be readily lifted axially during its rotation. As shown 1n detail in Figures 5, 6 and 7, the bearing block 13 for the spindle carries a wooden bearing member 28 having a bore for receiving the spindle, and on the outer side 1t is formed with an inclined cavity 30 in which the lower end of the spindle 12 is adapted to rest when lifted out from the bore 29, the bobbin being thus in the disengaged position.

Surrounding the standard 1 there is provided a holding seat 15 on which cheese, cop yarn, or hank yarn may be placed. From the cop A, the yarn is fed to the bobbm passing through the guide 16 and the guide hook 17, which are mounted on the ring frame 2,

"and through another guide hook 19 which is supported by the traverse frame 18 of ring vertical shaft 3 is a worm 20 meshing with a worm-wheel 21, the latter carrying a cam 22. The lever 23 pivoted at one end to the standard 1 is in operative engagement with said cam 22, preferably by means of a roller. At its other end the lever 23 is pivoted to a crosshead or collar 24 which is slidably mounted on the shaft 3, and this collar 24 is connected to the traverse ring frame 18 by means of rods 25. By the above-mentioned mechanism. the traverse frame 18 carrying the guide hooks 19 is raised and lowered upon the rotation of the vertical shaft 3, thus resulting in the yarn being fed under a regular tension.

At the bottom of the machine, beneath the holding seat 15, there is provided a round box for the reception of empty bobbins, while at the top of the machine on the upper ring frame 9 is mounted a box 27 for the reception of the loaded or full bobbins.

As will be seen from the foregoing description, in the winding machine according to this invention which is' made in ring or circular form, and in which many bobbins are arranged around and in contact with the rotating friction disc 5, an increased.

efliciency may be obtained, whilst the compactness of this form of construction enables the machine to be installed occupying "a smaller floor space per spindle as compared with the ordinary bobbin winding machine. the outer surface of the flange 6 of the rotating disc 5, the bobbin is engaged by said disc at one point only, so that wear of the yarn is decreased to a minimum, rendering the machine applicable to the winding of any dyed yarn. Owing to the slight tilting of the bobbin spindle in the direction of rotation of the friction disc, the bobbin is readily lifted slowly during the winding Because of the curved ormation of' operation, so that the winding operation may be accomplished producing a minimum breakage of the yarn and enabling the yarn to be wound tightly on the bobbin.

What I claim is 1. A pirn bobbin winding machine comprising a rotating disc coaxially mounted on the vertical driving shaft, a plurality of bobbins arranged around and in contact with the periphery of said rotating disc, an upper ring frame for supporting the upper end of the bobbin spindle, a lower ring frame for supporting the lower end of the bobbin spindle, a traversing frame arranged between said upper and lower ring frame, means for imparting to said traversing frame upward and downward movement upon rotation of the driving vertical shaft, and means for slowly lifting the bobbins during the winding operation, thereby causing the lower ends of the bobbin spindles to be withdrawn from the lower ring frame upon the completion of the winding operation.

2. A pirn bobbin winding machine as specified in claim 1, wherein said rotating disc is provided with an annular flange having a curved outer surface.

3. A pirn bobbin winding machine as specified in claim 1, wherein the bobbin spindle is slightly inclined to the vertical in the direction of rotation of said rotating disc.

4. A pirn bobbin winding machine as specified in claim 1, comprising bearing blocks mounted on said lower ring frame, each block having a central bore for the bobbin spindle and a cavity for receiving and retaining the lower end of the bobbin spindle upon the latter having been withdrawn from said central bore upon completion of the winding operation.

In testimony whereof I afiix my signature.
