To all whom/ it 71mg concern:

Be it known that I, V ICTOR BELANGER, a citizen of the United States, residing at Marshfield, in the county of Plymouth and State of Massachusetts, have invented certain new and useful Improvements in Spinning or Twisting Machines, of which the following is a specification.

This invention has relation to spinning or IO twistingmachinery; andits objectistwofoldfirst, to increase the production of such machines and, second, to enhance the quality of their product. Up to the present time the production of such machines has been limited :5 by the inability of the drag or traveler to revolve in practical operation more than acertain speed (say about ten thousand revolutions per minute) without the traveler being heated and flying off the ring and becoming 2o useless, the heating of the traveler being caused by its friction against the ring, which friction increases according to the rapidity of revolution of the traveler. Consequently to obtain a greater production from a frame it has been necessary to lengthen the same and increase the number of spindles, this requiring greater floorspace and entailing an increased eXpense to the manufacturer in providing such floor-space and the additional number of spindles, bobbins, and other necessary supplies, According to the present invention, however, I am enabled with the same number of spindles to greatly increase the production of the frame without materially 5 adding to the cost of the frame or the expense of operating endearing for the same. In addition, my invention admits of a much larger quantity of yarn being wound upon the samesized bobbins and of its being wound more uniformly, thereby savingin cost of spooling, and, moreover, it causes a decrease in the number of breakages and therefore in the number of knots in the yarn and makes a saving in waste. These several ends are acoomplished by reducing the friction of the drag, and thereby permitting its more rapid revolution or rotation, so that the spindle may be driven at the very high rate of speed which recent improvements in spindles have made possible.

My improvement consists, essentially, in so organizing the frame that in practice the ring will rotate freely when the spindle is in motion and when so rotating will be free to yield in any direction under unbalanced strains arising from unequal pull of the yarn or other causes. I claim to be the first person to accomplish this important result, and the following are the means by which I accomplish it:

Instead of mounting the ring stationarily upon the rail (as has hitherto been the practice) or supporting it in ball-bearings (as has heretofore been proposed) I mountit on said rail in such manner that it may move radially relatively to the spindle and preferably axially, by which construction the ring may rotate under tension of the yarn when the spindle is in motion, and the speed of rotation can be increased far beyond the former limit of speed of the spindle without causing 7o undue friction, as is the case where a traveler rotates upon a stationary ring or where it is attempted to rotate a ring in ball-bearings.

Various means of permitting the radial movement of the ring relatively to the spin- 7 5 dle (which constitutes the leading feature of my invention) and also the axial or up-anddown movement (which constitutes another important feature thereof) may be adopted.

In the form which I at present prefer and which I have shown in my drawings and described in the following specification, the ring is mounted on the rail within a casing or other means for limiting the movements of the ring in such manner that the ring is capable of radial and axial movement relatively to the casing. I find that in operation the ring is raised from its support by the tension of the yarn and rotates with infrequent contact with the casing. In fact, it would seem 0 that in this construction the ring when rotated is to all intents and purposes normally free from engagement with any inclosing walls; but I believe it to be important to have the casing yielding in this form of the invention, so as to soften any contact bet-ween the ring and easing which takes place in practice.

In order to prevent the breakage of the yarn in overcoming the inertia of the ring when starting the spindle, I have heretofore 10o employed a traveler of the common type and have constructed the ring with a race to re ceive it, so that when the spindle first begins to rotate the traveler moves around the ring,

which remains quiescent; but as the speed increases the friction of the travelerwith the ring is sufficient to cause the ring to revolve slowly at first and then with increasing speed until it seems to revolve in unison with the traveler; but I do not regard the employment of a traveler as essential to my invention.

In operating the machine, I have found the tension on the yarn between the yarn-guide and the drag to be very light, and that the yarn balloons to some extent, and hence I employa guide or ballooning-controller, which may be mounted upon the ring-rail and movable therewith and which causes the arc in which the yarn moves to remain constant; but notwithstanding the light tension on the yarn between the two points referred to the.

thread in building is wound more tightly and compactly upon the bobbin than in previous methods of ring-spinning. This invention, I have discovered, spins thread for warps or fillings with equal facility, and the same ring may be employed for yarns of various weights or grades. Moreover, the yarn spun with my invention possesses greater strength and elasticity than when spun with the machines hitherto employed.

Referring to the drawings, which illustrate one embodiment of my invention and on which similar parts or features are indicated by similar reference-numerals, Figure 1 represents in front elevation a portion of a spinning-frame embodying my invention. Fig. 2 represents a section on the line a a of Fig. 1. Fig. 3 represents an enlarged elevation, partially in section, the spindle-rail, spindles and bobbins, and my ring and traveler. Fig. 4 represents the same in plan view. Figs. 5 and 6 represent the ring and traveler at rest and in operation, respectively.

driven by bands, tapes, cords, or belts 7 pass ing with the ring-rail.

The ring-rail is provided with a plurality of apertures 11, through each of which a spindle and bobbin extend upwardly, and in each I aperture is placed a ring-casing or ring-retainer. The casings in the present form of the invention are each formed in two parts or sections, one of which is rigidly secured to the rail, while the other of which is supported 3 ieldingly upon the same. The lower section is indicated at 12, and it is formed with a depending annular flange 13, which fits snugly in the aperture 11, the upper surface of the section being Hat and smooth, so that the lower edge of the ring may rest upon it, as shown in Fig. 10. The upper section or half 14 of the casing is ring-shaped (see Fig. 11) and may be formed with oppositelyarranged ears or lugs 15 15, apertured to receive screws 16 16, which fasten the casing on the rail. The apertures 17 17 in the lugs 15 are larger than the screws 16, so that the upper section of the casing is capable of being translated bodily vertically and also in any direction in a plane parallel to the face of the rail, and spiral springs 18 are placed under the heads of the screws in the counter- "sinks to hold the said section yieldingly in place. The upper part 14 of the casing has a concave inner surface 19,substantially similar to the inner surface of a truncated semisphere, for a purpose which will presently be apparent. The internal diameter of the lower portion of the upper section of the casing or retainer is greater than that of the lower section, so that there is provided an annular chamber with a fiat bottom wall and an inwardly-curving side wall, within which the ring is confined. The casing may be formed of any suit-able metal or a metal alloy, or it may be constructed of any suitable composition of pulp or fiber.

filled with elastic packing or other yielding material which would permit the desired movement of the ring within the casing, there would still be a space within my meaning. At its upper end the ring is formed with an upwardly-projecting annular flange 25 and a similar downwardly-projecting flange 26, which constitute a race for the traveler. A concentric outer guard flange 27 may be formed on the under side of the ring, which forms, with flange 26, a groove to receive the end 23 of the traveler 20.

The yarn is passed from the delivery-rolls 1 1 and the pigtail or guide at through the traveler to the bobbin, the ring resting quiescent upon the lower part of the casing, and when the spindle and bobbin are rotated at high speed the pull of the yarn upon the traveler causes the latter to revolve about the race on the ring. The friction of the traveler on the race causes the ring to rotate first slowly and then more rapidly until the traveler and ring appear to be moving in unison. The tension of the yarn as it is built upon the bobbin raises the ring from the lower section of the casing, and to the observer it seems to revolve out of. substantial contact with the casing. Apparently it eventually finds its center of rotation and revolves freely with little or no friction against the casing.

The main tension or stress upon the yarn is at points between the traveler and the bobbin, whereby the yarn between the traveler and the pigtail has a tendency to balloon freely, and hence to regulate the ballooning I employ any suitable device which will confine the yarn and render the are through which it moves substantially constant. The one which I have illustrated in Fig. 13 may be employed for this purpose. It consists of a standard 28, adjustably secured to the guard-rail 10 and terminating at its upper end in a shoulder-screw 29 to receive a plate 30. The plate is held in place by a milled nut 81, and it is formed with two tapering curved arms 82 82, whose inner edges form a semicircle. On the outer ends of said arms and in bearin gs formed on or secured to their outer edges are journaled two fingers 33, whose free ends overlap and complete the circle, of which the inner edges of the curved arms form a part. The rear portions of said fingers are straight, and their ends are bent at an angle to receive weights 3%, which normally hold the front portions of the lingers in the positions shown in Fig. 13. With this construction a circular guide is provided which controls or regulates the ballooning of the yarn, whereby the angle made by the yarn as it passes from said guide through the traveler to the bobbin remains constant. The bobbin enters the guide as the ring-rail is lowered, and at such time the bobbin maybe doffed, since the fingers automatically yield and rock in the bearings when the guard-rail is thrown backward, and the bobbin is thereby forced against their ends to permit its removal.

Atwistin g or spinning frame equipped with my invention is capable of a much greater production than has ever been possible with any other frame heretofore proposed or used, and, in fact, its production is limited only by the highest speed at which the frames may be safely driven, and so far as I have been able to observe the number of breakages in the yarn in a given length thereof is much less than where the ordinary frames are used. This seems to be due to the fact that the drag moves with substantially no frictional contact with the casing and that therefore there are no sudden jerks and strains upon the yarn, and in this connection it will be seen that not only is the ring capable of moving relatively to the casing, but in case the ring contacts with the casing the latter yields slightly and imposes no rigid abutment to prevent it from free revolution.

The shape of the ring and the casin g appears to aid in the ring finding its center of rotation under the pull of the yarn, and I am led to believe that an air-cushion is formed between the ring and its casing.

The invention is applicable for use in connection with yarn of all kinds and grades, from the lightest to the heaviest, and maybe employed for twisting as well as spinnin Moreover, I am able to spin yarn suitable for both warp and filling. The tests which I have made upon yarn spun by my invention seem to indicate that it is more elastic, more even, and much better in many respects than the same grade of yarn spun by other frames.

The same ring and traveler may be used for yarns of different grades, though I prefer to form them according to the work which they are to perform.

In employing the term casing as defining the retainer for the ring I mean to include any contrivance for limiting the movement of the ring by which the ring is enabled to perform its described functions in twisting and laying the yarn upon the cops or bobbins.

It is evident that the invention is limited in no wise to the details of construction which I have seen fit to illustrate and describe, for, so far as I am aware, I am the first to provide a drag consisting of a revoluble ring which is movable radially or laterally, whether used with or without a traveler.

.llaving thus explained the nature of the invention and described a way of constructing and using the same, although with out having attempted to set forth all of the forms in which it may be made or all of the modes of its use, I declare that what I claim is- 1. In a spinning or twisting frame, a rotatable ring freely yielding in any direction under unbalanced strains.-

2. The combination of a rotatable ring capable of radial movement relatively to the spindle under the stress of the yarn, and means for limiting the movement of the ring.

3. The combination of a rotatable ring ca-- pable of axial movement relatively to the spin die under the stress of the yarn, and means for limiting the movement of the ring.

4. The combination of a ring-casing, and a rotatable ring capable of radial movement relatively to said casing.

5. The combination with a ring-casing, of a rotatable ring loosely confined by said casing to yield perceptibly laterally.

15. The combination of a ring-casing and a ring movable radially and axially relatively to said casing, said ring and easing having adjacent surfaces curved in the direction of their axes.

16. A dra'g for a spinning or twisting frame consisting of a bell-shaped ring.

I 17. A drag for a spinning or twisting frame consisting of a bell-shaped ring having a race to receive a traveler. r

18. The combination of a radially-movable rotatable ring, means for limiting the radial movement of said ring, and a traveler revoluble on said ring.

19. The combination of a rotatable ring axially and radially movable relatively to the spindle, said ring having a race, a traveler revoluble about the said race, and means for limiting the described movement of said ring.

20. The combination of a rotatable ring having a race, a traveler revoluble about said race, and yielding means for limiting the radial or axial movement of said ring.

21. The combination with a rail and a yarndrag supported thereon, of a ballooning-regulator carried by the rail and adapted to inclose the bobbin, said regulator having rockin g weighted arms releasing the bobbin when moved laterally.

22. The combination with a rotatable ring capable of axial movement relatively to the spindle under the stress of the yarn, and means for limiting the movement of the ring, of a device for regulating the ballooning of the yarn.
