.11 Claims. 1

The present invention relates to spinning, twisting and like apparatus, and more in particular to improved mechanism to replace the spinning rings, travelers, flyers, throwers and the like on present forms of spinning and twisting machines.

The chief objective of prior art machines as well as that of the present invention is to wind roving or fiber upon a spindle while simultaneously applying a twist to the fiber to make it stronger and keepin the same under tension during the winding period. Since modern :production methods demand high rotative spindle speeds, it is readily apparent that such .a device must be well constructed and balanced to withstand the high rotative speeds, yet delicate enough to handle light fibersin giving the necessary twist and applying the proper tension during thewinding period.

Another object of the invention is to provide mechanism which makes itpossible to runspinning and twisting frames at rotative speeds higher than permissablewith those machines of the prior art.

Another object of the invention is to provide apparatus of the character described which provides uniform twistingof the fiber while applying constant tension to the same as it is being wound upon the cylinder.

A further object of the invention is to provide apparatus which eliminates all of the priorart reciprocating traveling-mechanism formerly. used, and provides an air driven, rotating traveler drum, which is spun in botha vertical and a horizontal plane to impart twisting andwinding to the fiber into a package.

Another object of the invention is to provide apparatus which eliminates the .ring travelers of the prior art devices.

Another object of theinvention is to provide spinning apparatus which maintains .uniform tension'from anempty package to av full one.

Still another object of the invention is toprovide apparatus. permitting. the winding of i a. larger packageof the fiber than hertofore accomplished,

Further objects and advantages will become apparent inthe course .of the followin detailed descriptionofv the inventionwhenviewed together withthe accompanying drawing in which:

Fig. 1 is a vertical cross sectionotanembodimentof my invention inspinning, twisting and like apparatus.

Fig.2 is atop view thereof.

Fig. 3 is .averticalsectional View taken along lines 13- 3 or Fig.1.

,-.In the drawin nu e I 0 .de isnat s armdrical pot the bottom I l of which is provided with an upset boss 12 having an axial were I 3 by which the same may be mounted on any vertically disposed rotatablespindle.

On the inner wall surface of the pot I0 I have provided two diametrically opposed guide bars I4, disposed vertically along the pot walls and held in position by means of screwsl5. Each guide bar [4' is provided with a 'slot I16 on its inner face extendin from the top end to a point near the bottom thereof.

Fitted over the top of the not H] I have provided a flanged rim I1 having diametrically opposed, elongated slots {8 formed on the top face thereof.

"Ifhe guideor driving drum i9 is mounted on a shaft 20 having sealed anti-friction bearings 2| on each end thereof and adapted to ride in the slots [6 of the guide bars l4, and provided with convex Caps 2 to prevent wedging in the slots. Mounted oneach end of the driving drum is are air vanes 22 held to the drum proper by means of screws 23 or the like. In cooperation with these vanes 22 I have provided troughs 24, the bottoms of which are extended through the bottom of the pot It). At the lower ends of these troughs 24 I have provided gate valves 25 which are pivoted at 25" and which control the quantity of air passing up through the troughs 24 to the vanes as the pot is being rotated by the spindle.

-It will be noted that upon the periphery of the traveler drum i9 Ihave formed a groove 26 constituting oppositely inclined spirals which operate to reverse the traverse of the strand whereby the fiber is moved backward and forward during its winding period.

Above the traveler drum and resting on the same is the cylinder 21 alsomounted on a shaft 28 whoseouter ends are mounted in anti-friction bearings 28' to ride in the slot l6 of the guide bars [4. Convex bearing caps 28" are provided to prevent wedging inthe slots.

In the inside bottom of the pot Ill I have .provided opposed cross bars 29 positioned in the manner shown in Figs. 2 and 3. In operating the device, the thread or yarns are brought through a thread guide (not shown) preferably located over the central vertical axis of the pot, inaccordance withstandard practice, and then extended through one of the slots 18 of the upper flanged rim l1, and brought down under the corresponding lower cross .bar 29 and positioned .in the spiralgroove 2B cutinthe faceof the traveler drum I 9, and finally wound around in a cross spiral on the cylinder 21.

Witha fixe'd spindle speedand a given area of 3 opening of the gate valves 25 for the admission of air, there is provided a constant speed of rotation for the driving drum l9 and consequently a constant, uniform tension on the fibers. The cylinder 21 onto which the fibers are wound is rotated with a constantly changing speed as the yarn builds up on it, and this change in speed or difference between the speed of the drivin drum and the speed of the cylinder causes the yarn to be wound so that succeeding turns are spaced out across the cylinder to fill all the space uniformly rather than to have each successive 7 mounted for vertical movement in said pot, and

layer directly on top of the preceding, as would i be the case if the speed of the cylinder were constant.

Since the cylinder 21 rests upon the drivin drum l9, it will be driven by the driving drum and will rotate in the opposite direction thereto, winding the threads or yarns in a criss-cross spiral. 'Very, very light tensions are necessary in spinning, and the size of applicants driving drum and winding cylinder are such that the finest threads will overcome the friction in the antifriction bearings in which these rotating parts are mounted; and the fact that constant, uniform tension is maintained all the Way from an empty package to a full package permits extremely high spindle speed to be employed.

The size of the package produced on my apparatus will be five times as large as that produced by a 2 spinning ring operatin on the present spinning frames. This means a continuous thread without knots with a sufficient yardage to make a full beam to be put on as warp on the looms, and the doifing period is five times as long as with the present day 2" spinning ring. My package can be taken directly from the spinning frame and placed on a high speed beamer, thus eliminating a very expensive machine and an expensive operation in rewinding and knotting such as is now practiced.

' My device is versatile and will handle all types of natural and synthetic fibers in either slack or hard twist. It can be installed on presentspinning frames withonly a slight change in the geared end of the frame. No ring travelers are used, so that the cost of travelers is eliminated as well as the cost of installing and changing them;

and the use of my device further removes theneed on present spinning frames of all the ring rails, lifting rods, counterweights, gearing and builder cams and cam followers.

It will be obvious that my invention provides needed apparatus of great convenience and usefulness, and that while I have illustrated and described my invention in a very practical embodiment thereof without attempting to illusztrate. or describe other embodiments thereof which I contemplate, various modifications and changes may be made without departing from the scope of my invention as defined in the appended claims.
