Specification of Letters Patent. 7 I 1}"agtented l t/lay 1917,

Application filed December 31,1914. Seria1-No.879, 875.

To all whom it mayconcer'n:

Be it known that I, ADELBERT P. HINE, a citizen of the United States, residing in Woodbury, in the county of Litchfield and State of Connecticut, have invented certain new and useful Improvements in Spinning- Rings, of which the following is a specification.

This invention relates to that class of rings whichare used in the art of ring spinning, and which are provided with tracks or guide surfaces for the thread-carrying travelers. Owing to the high-speed of the travelers,-commonly reaching eightthousand revolutions per. minute,these rings require their track-surfaces to be made extremely hard, and also extremely smooth. And owing to the short life of the rings, whereby the Consumption of them aggregates many millions per annum, the requirements of the tradehave become most exacting, not onlyas to relative durability and precision, but also for a greater value with a reduced cost. It is, therefore, the object of my present improvements to furnish a spinning ring having superior operational qualities, and one which, while adapted to be made of sheet or plate metal, shall also have a simple construction in which the track-surfaces will be formed on one surface only of the metal, while the sectional form shall be such as to favor the necessary hardening and polishing operations with a minimum impairment and def ormation of the metal.

In the accompanying drawing, Figure 1 is a plan view,shown partially broken away,-of,a sheet-metal spinning ring made in accordance with my present invention.

Fig. 2 is a vertical section in line 2, 2, of Fig. l.

Fig. 3 is asectional view similar to Fig. 2, for illustrating a modified arrangement of certain features.

Fig. 4 is anenlarged transverse section of the ring, asjshown in the left-hand portion of Fig. 2, for more fully. illustrating the track-zone locations and the relation of the ring-head to atraveler carried thereon.

Fig. 4 is a partial plan view as seen from above in Fig. 4L, these two figures being drawn in alinement to facilitate comparison thereof. 4

Figs. 5 and 6 are views similar to Fig. 4, for illustrating certain features in modified arrangements, plained.

Similar characters designate like parts in all the views.

In Figs. 1, 2 and 3, the hollow ring head is designated by H, the annular web by N, and the base, or base-fiange, by B. In Fig. 2, the inner portion of the hollow head H is shown joining the web N, while in Fig. 8,'that arrangement is reversed; so that here the outer portion of the head (here designated by H) joins the web N; of these two arrangements, the one shown in Fig. 3, is also shown in Figs. 4E and 5, while the arrangement'of Fig. 3 is the one shown in Fig. 6. In Figs. 1, 2, 3, 4 and 5, some space is indicated at S, but the proportionate amount of this space may be varied. In Fig. 5 the modified form of the head H is further distinguished by H and, similarly, in Fig. 6, by H H, this member has an interior space, C, so that at no point is there any doubling or folding of any part of the sheet-metal upon another part thereof. A

The web N, of the ring preferably consists of an annular member and is herein shown made of a single thickness of metal. On the lower edge thereof, the web N joins with a base member, as B, which is preferably of the form (substantially as shown) of an outwardly-extending flange having,- relatively to the height of the web,a considerable width radially of the ring, this being the arrangement herein illustrated in all the views. In this construction, the base-and-web portion of the ring is in the nature of an annular device having in section an L-shaped form (Fig. 4), and having the section'so proportioned as to afford a high degree of stability and resistance to injury, with a minimum of metal, and of cost of manufacture.

On its upper edge, the web N is shown reinforced and stiffened in a corresponding manner. The juncture attheangle-or bend 2, of the web N, integrally joins the web with the head H, and in j a directionv laterally thereto at the line of said juncture, so that by such angular construction, each said part operates as a stiffening member for the other. Thus the immediately adjacent and comas hereinafter more fully ex- 'bined portions of. the web and head have substantially an L-shaped form, while the In each form of the head.

base and web, together with that part of the head which is contiguous to the web, form a section having a s o-called Z-shape, which ment, as shown in Figs; 2, 4, and 5, the

angle-portions at 2 and 3, are located in re versed directions, respectively; this provides for direct and free access to the interior of the angles by tools used in finishing the rings, and, later, for polishing and cleaning the hardened rings.

The ring proper may be saidto com-v prise the traveler-tracks, and these may con sist'of arcs or segments, each havinga similarity of relationto a geometric center or axial line. In Figs. 2,4, 4 thosearcs or zones comprise the outer-track surface, or track-zone, 4, and the inner track-surface, or track-zone, 5, and these arcs or zones are each shown of the form of a circular-arc, and, also, each said are is of a similar radial distance from the center-point, or axial line :0. These respective radial distances may, however, be varied, and be unlike'in measurement, without changing that similarity of relation which consists in the concentricity relatively to said axial line, which is located within the. space C, of the hollow head-portion H, of the rings Such an arrangement is illustrated in Fig. 5, where the respective track-zones or segments 4and 5 are each concentric with relation to the axis 00, although one said segment has curvature different from the other. i

In Fig. 4, the head is shown in transverse section, and in the form of ring shown in this figure, the inner and outer track-zones 5, 4, are of convex curvature outwardly rela tively to the axis w, and constitute integrallyconnected single-thickness parts of a headsection which is of a continuouscurvature throughout the sectional circumference thereof. These features are also found in a somewhat modified form, in the constructions illustrated in Figs. 5 and 6, as will now be evident. I I

One feature of my present improvements is the provision, on the head of the ring, of two oppositely-disposed trackzones each 7 having 1n the plane of the ring axis, a con vex curvature throughout the width thereof. One of these track-zones,'as 4, is the outside track, While the opposite said zone, as 5, Fig. 4, is the inside track. In the preferred form and arrangement, each of said zones is in the form of a segment which, (as indicated in the enlarged sectional view Fig; 4), constitutes a part of a head member that in section is of a continuous curvature throughout the cross-sectional extent, or circumference thereof. In the form, shown in Fig; 4, this continuous curvature is substanthe track-zones.

tial'ly uniform throughout the, circumference of the head H, so that the outer track-segment 4'is connected with the inner'traclzsegment 5, by an intermediate portion, or

top-zone, as 6, having the'same curvature as may. have, not only 'a continuous, and, ex-

ternally, a convex and outwardflcurvature throughout the cross-sectional length,orextent thereof, but this curvature may be uni' form in amount in allparts of that length, and the oppositely-located segmental .pjortions thereof may constitute bearing-zones which are of equal convexity the onewith theother. j V Y A further featureof the forms of ringhead as shown in the drawing, is that the head may have the metal in all portions thereof, curved in two directions, and in directions substantially transverse to each other in any one part of the ring-head. For instance, in Fig. 4,-when compared with Figs. 1 and 4'-*,it will be seen that each part of the outer track-zone 4 is curved convexly as regards a plane transversely of the ring-axis 00, and is also curved convexly relatively to, or in, a plane at right-angles to said axis, (as seen in plan View), and thus has a double-convexity. On the inner trackzone, however, the metal, while curved con- Thus the head 'member' which one pair is located in a reversed arv rangement relatively tothe other pair.

The construction heredescribed has the important advantage that during the forming processes the metalin the head H, is subjected to a forming-action which throughout the head, is of a minimum degree of variation, and which therefore leaves the metal of the entire head-portion of the ring with the highest degree of uniformity, and with a minimum degree of structural or molecular impairment. 'One object of this construction is to obtain by means of qualitieshere pointedout, a corresponding uniformity of result When the rings are later subjected to the operations of hardening and polishing. Since the exterior track-zone surfaces require extreme hardness, the uniformity of the metal in the head, tends materially to secure uniformity of surface hardness and'texture, and also tends to reduce to a minimum the distortion and breakage ordinarily resulting from the heating and hardening processes. These losses are frequently excessive, and even under favorable conditions have heretofore been suflicient to materially increase the cost of manufacturin spinning rings of the ordinary kinds, besides decreasing the average life of the usable product of such manufac-' wrought into rings by the aid of highly finished dies and tools, so that subsequently to the hardening, only a slight degree of re-polishing will be required.

In the forms shown in Figs. 5 and 6, the ring-section may be said to comprise two arcs, preferably circular, Which, though on different radii, are substantially concentric (especially when they are circular arcs) to the same center, as w. The traveler, as T, is non-reversible, being incapable of being put into any working position, unless applied in one'and the proper way. This feature permits of a construction whereby to minimize the so-called wedging-action which normally occurs to some extent when the ring-section is made up of circular arcs of equal radii, .as in Fig. 4. In Figs. 4, 5, 6, theapproximate direction of the draft of the thread, is indicated by the arrows 7, while in Figs. 4, 4*, an ordinary arrangement, (or position) of the thread is indicated by 8.

In Fig. 4*, the thread 8 is shown running toa bobbin located at 9, centrally of the ring,

in a well-known manner. The improved constructions of the traveler T, which are herein shown for more fully illustrating the construction of the ring, are not claimed herein, but are reserved to constitute in part the subject-matter of a separate application to be concurrently pending herewith.

Having thus described my invention, I claim:

1. A spinning ring comprising a hollow head having integrally-connected inner and outer track-zones which in transverse section are curved in opposite directions, respec tively, one of said track-zones having the transverse curvature thereof greater than such curvature of the other said zone, and said track-zones being each located concentrically with relation to one axial line within the space of the hollow ring-head.

2. A spinning ring comprising a hollow head having integrally-connected inner and outer track-zones which in transverse section are curved in opposite directions, respectively, and each with an outward convexity, said outer track-zone having the transverse curvature thereof greater than such curvature of the inner said zone.

3. A spinning ring comprising a hollow head portion having inner and outer trackzones which in transverse section are curved in opposite directions, one of said trackzones having the transverse curvature thereof greater than such curvature of the other of said zones in combination with a loop-form traveler having converging curved ends which respectively are adapted to bear on said track-zones of the ring.
