Harold Livesey, Spondon, near Derby, England, assignors to Celanese Corporation oi America, a corporation of Delaware Application August 20, 1935, Serial No. 36,942 In Great Britain September 3, 1934 '7 Claims.
This invention relates to textile apparatus, and particularly to cap-spinning apparatus for the twisting and winding of threads, the object of the invention being to extend the usefulness of cap-spinning devices both as to speed of operation and size of package to be formed by such devices.
The cap of a cap-spinning device is carried by the upper end of a stationary spindle extending upwardly through the axis of the bobbin or other package support surrounding the spindle, the cap depending about the package support so that its lower edge forms a guide to conduct the thread to the support. Traversing of the package support along the cap spindle causes the thread, which has been twisted by its rotation about the cap after leaving a balloon guide disposed some distance above the cap, to be traversed along the support by the cap edge. Winding of the thread takes place at the rate at which the thread is delivered to the balloon guide, the revolutions of the package support in excess of those necessary to effect the winding serving to impart twist to the thread.
Since only the package support rotates, the cap-spinning device is capable of high rates of twisting, and is particularly serviceable for applying twist to threads delivered at a high rate, as, for example, in the production of artificial silk threads by the dry-spinning operation. It has been found, however, that with high package speeds and/or with large package supports vibration is sometimes set up in the cap, no doubt due to the necessary disposition of the cap at some distance above the point at which the cap spindle is secured to its supporting rail. The present invention reduces this tendency to vibration, and its consequent interference with the twisting and winding operation.
According to the invention the cap is provided with damping means comprising a mass capable of limited movement with respect to the cap.
The movement of such a mass may be limited by the boundaries of a cavity in the cap and in which the mass moves, and/or by spring means. Such spring means may also serve to secure the mass to the cap.
In the accompanying drawing a number of capspinning devices in accordance with the present invention are illustrated.
Figure 1 shows an elevation in section of a capspinning device in which the mass is located in a cavity in the head of the cap.
Figure 2 illustrates a device in which the mass is in the form of an annulus anchored to the neck of the cap by means of springs.
Figure 3 is a plan View of Figure 2.
Figure 4 shows a modified form of the device shown in Figures 2' and 3.
Figure 5 shows a further form of device in which the mass is in the form of a'weight arranged eccentrically with respect to the neck of the cap.
, Figure 6 is a plan view of the device shown in Fig. 5.
Referring to Figure l, a cap I in operation is supported on the spindle 8 fitting into the tapered bore in the boss 9. The cap is provided with a false top I!) which forms the cavity II in which iron filings, sand or other hard granular material !2 is placed.
Referring to Figures 2 and 3, the cap I3 has anchored to the neck It thereof by springs IS an annulus [6, for example of lead.
Referring to Figure 4, anchoredto the top of the cap l3 by the springs I! there is an annulus I8.
Referring to Figures 5 and 6, the cap I 3 has anchored to the neck l4 thereof the weight 19 by an extension'of the spring 20.

1. A cap spinning device provided with damping means said device comprising a non-rotary cap, a mass located in proximity to the head of said cap, and means for retaining said mass on said cap, said means permitting a limited movement of said mass with respect to the axis of said cap and resisting such movement. a
2. A cap spinning device having a cavity located in the head of the non-rotary cap adapted to receive granular material and to permit limited movement of said material with respect to the axis of the cap.
3. A cap spinning device provided with damping means comprising a mass located in proximity to the head of the non-rotary cap and spring means securing the mass to the cap and permitting limited movement of said mass with respect to theaxis of the cap.

5. A cap spinning device comprising anonrotary cap provided with a cavity in the head thereof and a mass that is located in said cavity whereby said mass is permitted'limited movement with respect to the axis of the cap and such movement is resisted by the interior surface of said cavity. a
'6. A cap spinning device comprising a nonrctary cap provided with a cavity on the head thereof and a mass of granular material that is located in said cavity, whereby said mass is permitted limited movement with respect to the axis of the cap, and such movement is resisted by the interior surface of said cavity.
7. A cap spinning device provided with damping means comprising a non-rotary cap, a. mass located in proximity to the head of said cap and spring means for retaining said mass on said cap, said spring means permitting a limited movement of saidmass with respect to the axis of the cap and resisting such movement.
