Specification of Letters Patent. Patented Nov. 23, 1915.
Application filed August 16, 1915. Serial No. 45,623.
the following description, in connection with the accompanying drawings, is a specificae tion, like characters on the drawings representing like parts.
This invention relates to spinning rings and particularly to stationarily mounted spinning rings.
In order that the principle of the invention maybe readily understood, I have represented a single embodiment thereofin the accompanying drawing, wherein Figure 1 is a plan view on an enlarged scale, of a spinning ring embodying my invention; Fig. 2 is a vertical, central section thereof also on an enlarged scale; and Fig.
'3 is a vertical section through one side of the ring on a still more enlarged scale.
An important object of my invention is to provide a spinning ring of such construction as to result in amaterial reduction in the friction of the traveler thereon. further object is to provide a spinning ring of such construction that the traveler can be more readily applied thereto and without straining the traveler, thus materially re-- ducing the weight thereof.
A still further object is to enable the use. of heavier travelers than heretofore in spinning various counts of yarn.
Further objects of the invention will be set forth hereinafter.
So far as I am aware, no successful spinning ring has been produced, except by forging, which is machined down and then case-hardened and polished. The ring heretherefore of true circular form, a desideratum not secured through the use of sheet metal.
The preferred form of traveler is one formed of mild steel, case-hardened. Economical commercial production requires all travelers to be symmetrical in form or double ended, so that they may be placed upon the ring without any requirement that one end or the other be made the inner end. In accordance with the preferred embodiment of my invention I have provided a ring peculiarly adapted to receive a traveler of such double-ended formation, though my invention is not limited to the use of such a traveler. p
Referring'more particularly to the drawing, the spinning ring is indicated generally at 1. While the ring is preferably stationarily mounted upon the ring frame in any usual manner, it may be of the so-called rotary type. It is formed as a forging, machined down and case-hardened and polished, and therefore is of a unitary structure.
I have herein represented it as having a lower or basal flange 2, which may be of any suitable construction, not herein necessary more fully to set forth. The ring is provided with a body portion 3 and an upper or I traveler flange or race, indicated generally at 4:. The said traveler flange is composed of a portion 5 extending inward from the body portion 3, and a portion 6 extending outward therefrom. Preferably, the traveler flange is of slightly less width than heretofore. At its inner edge, the said flange may be of usual or desired vertical thickness or extent and is herein represented as curved orrounded in vertical section.
The traveler is indicated generally at 7, it being preferably double-ended. The centrifugal action due to spinning throws the traveler downward, and hence it must be bowed up considerably from the ring so as to allow the yarn suflicient space and so as not to make contact with the ring. Such centrifugal action tends to throw the outer terminal of the traveler in close'to or in contact with the vertical wall or body supporting said flange.
Not only does the centrifugal action tend to throw the traveler outward and to force its inner end against the inner flange of the ring, but the pull of the yarn tends to trip the traveler and lifts its outer end, the greater part of the wear being borne by the inner end of the traveler. The pull or strain of the yarn in spinning is, however, constantly varied, due to numerous causes, among which may be mentioned the traverse motion of the frame and the different diameters of the bobbin onto which the yarn is laid and the uneven pull upon the yarn. The result is that in the spinning operation, the traveler has a rocking and unsteady motion, the outer end thereof rising and falling due to said and perhaps other causes. The higher the speed, the more frequent the rocking motion of the traveler and the greater will be the wear upon the inner end thereof,
owing to the increased centrifugal force exerted. The said rising and falling movements of the traveler result in intermittent contact of the inner surface of the traveler with the top surface of the spinning ring traveler flange, thus greatly increasing the friction between the ring and the traveler.
It has heretofore been proposed to form the top surface of the traveler flange with a downward slope to a thin outer edge. In practice, this has resulted in a marked decrease in the friction between the ring and traveler. The ring herein disclosed is an improvement upon such form of ring.
The inner edge of the traveler flange is indicated at 8, it being preferably of the usual vertical extent. The outer edge of said ring is indicated at 9. It is preferably thin and is outwardly directed and in thepreferred embodiment presents a single circumferential line. The top surface of the traveler flange is concaved or recessed, as indicated at 10, from a point substantially at the top of the inner edge 8 substantially to the outer edge 9. Thus the top surface of said traveler flange lies below a straight inclined line joining the top of said inner edge 8 and said outer edge 9. While within the scope of my invention, the angle or degree of slope of the top surface may be varied, I have obtained excellent results when employing substantially the slope indicated. While preferably the recessed or concaved portion of the top surface of the traveler flange extends to or substantially to the inner vertical edge of the traveler flange, such concaved or recessed formation or portion may terminate at an intermediate point between the innerand outer edges. The best results, however, are secured by having the recessed or concaved portion extend to or substantially to said inner edge.
While the under surface of the traveler flange 4 may be of suitable construction, I preferably form the under surface 11 of the inner portion 5 of the traveler flange in a horizontal plane, thus providing a substantiallv sharp, inner angle 12, where said surface 11 merges into the surface of the body portion 3 of the ring. The under surface 13 of the outer portion 6 of the traveler flange, while generally horizontal, preferably has an inner curved portion 14 merging into the outer surface of the body portion 3 of the ring.
In the disclosed embodiment of the invention, the thin outer edge 9 lies below and edge and also the concaved top surface, I am not aware that a concaved or top surface of a spinning ring is old per 86. I therefore desire to claim such feature of my invention broadly, inasmuch as in certain embodiments thereof, it may be employed apart from the other features of the invention.
The thin outer edge of the traveler flange permits a traveler to be positioned upon the flange by slight finger pressure, inasmuch as even though the traveler be very slightly expanded in pushing it past the thin edge, such condition of expansion exists but for an almost inappreciable length of time. \Vith an outer flange of usual thickness, it is necessary to expand the traveler by a tool in applying such traveler to the ring.
The concaved or recessed top surface of the traveler flange affords a larger air space beneath the traveler whereby the traveler is kept cool and less liable to magnetize or burn off when running at high speed. Moreover, it is my belief that the thin outer edge of the traveler flafige assists in a rapid dissipation of heat generated in the ring incident to the spinning operation.
Obviously the lower flange of the ring may be of the same construction as the up per flange, thereby making the ring reversible.
I have found that in the practice of my invention I can employ heavier travelers than heretofore, thus winding the yarn more tightly and permitting more yarn to be wound in a single package. In accordance with my invention, I have provided a spinning ring having an upstanding body and a traveler flange, said flange having an outer, sharp or thin edge markedly increasing in vertical thickness inwardly from said edge, the under side of the outer portion of the flange extending directly to and merging into the upstanding. body and the top of said flange sloping upwardly and inwardly to provide a friction reducing inclined zone, the inner edge of the flange being of markedly greater vertical extent than said outer edge, and said outer edge being in a transverse plane that is below the plane of the under side of the inner edge of said traveler flange.
Having thus described one illustrative embodiment of my invention, I desire it to be understood that although specific terms are employed they are used in a generic and descriptive sense and not for purposes of limitation, the scope of the invention being set forth in the following claims.
Claims- 1. A spinning ring provided with a traveler flange having a thin, outer edge and an inner edge of greater vertical extent, the top of said flange being circumferentially concave 2' A spinning ring having an upstanding body and a traveler flange, said flange having an outer sharp edge markedly increasing in vertical thickness inwardly from said edge, the under side of the outer portion of the flange extending directly to and merging into the upstanding body and the top of said flange sloping upwardly and inwardly to provide a friction reducing inclined zone, the inner edge of the flange being of markedly greater vertical extent than said outer edge, and said outer edge being in a transverse plane that is below the Plane of the under side of the inner portion of said traveler flange. g
