SPINNING-RINGS.- Y

Specification forming part of Letters PatentNo. 180,611, dated August 1, 1876; application led May 26, 1876.

To all whom it may concern Be it known that I, WLLLIAM H. MAGEE, of Woonsocket,in the county of Providence and State of Rhode Island, have invented an Improved SpinningRing, of which the following is a specification:

This invention relates to a spinning-ring, and has particular reference to the position or 1 location of the'race on which the traveler runs.

The office of the traveler in spinning is to j produce drag on the thread, keep it smooth and uniform, and permit it to be wound on the bobbin as tightly and evenly' as possible, without breaking or stretching the thread, which is directed by the traveler to the bobbin as the ring-railis raised and lowered.

In the ordinary ring the thread meets thev traveler near its center, and the centrifugal force of the traveler, in its rapid rotation, is sufficient to cause the outer end ot the trav' eler to rise and drag its inner end against the 1 inner side of the ring and under side of the race, while the' outer-end runs clear of the race, the friction producedbein' g, therefore, on but one end of the traveler, which causes the traveler to move unsteadily, or oscillate at its outer end, causing an unsteady drag on the thread, which breaks it or makes it. rough, and the traveler so lifted is sometimes pulled or thrown from the race.

Sonie -rings have been provided with inclined and beveled races, arranged at the inner portions of the rings, as in United States Patents Nos. 24,681 and 24,169; but it will be noticed that the strain of the thread on the traveler and the action of centrifugal force tend to lift the traveler, and cause it to bear at its inner and lower end against the ring with greatest force.

A race arranged lower on the inner than the outer portion of the ring obstructs the winding operation, and the draft cannot be made as steady and uniform as it would were the race located lowest at the outer portion ofthe ring.

Figure l represents one of my improved rings in section and applied to a bobbin, and Fig. 2 represents a section of au ordinary racel and a traveler.

My improved ring is provided at top with an outwardlyinclined race, a, on which is placed a traveler, b, through which the thread c is led, it passing from the usual guide-eye through the traveler and onto the bobbin, tube, or spindle. This race is inclined, substantially as shown in the drawings, and is provided at its inner portion with an inclined or rounded way, c, against which the inner end of the traveler moves; and at its extreme outer edge f the traveler is rounded or chainfered, to permit the thread toengage the traveler very close to its inner end, and so that the yarn extending from the bobbin to the trav- 4eler will be substantially on a level with the extreme upper' edge g of the inner ange, such edge being located in a circle of larger diameter than the circle formed by the annularlyprojecting portion h, just below the edge g.`

By constructing the race and placing it in an inclined position, substantially as described andl shown, and so that the traveler, in its rotation'about the race, will, owing to its cen- 'trifugalactioin keep both its ends against the ring, I am enabled to use a very light traveler, and one by which the uniformity of the drag on the thread may be increased, for when both ends of the traveler bear constantly on the ring it will loe` obvious that its motion will be more uniform and steady, and it will not oscillate as does the traveler on an ordinary ring, so constructed that both ends ofthe traveler fail to find a constant bearing thereon.

Another important advantage gained by the location of the race as described is that the yarn is enabled to encircle and pull against the traveler much nearer its inner end than has been heretofore the case, and this insures a steadier draft than is the casewhen the yarn passes about a traveler near its center.

The centrifugal action of the traveler, in connection with the upward draft of the yarn, tends to keep thc outer end ofthe traveler always against the outer portion of the ring-race, and the force with which the inner end of the traveler bears on the ring is varied according to the draft between the bobbin and traveler. When the bobbin first receives the thread the yarn extending from the bobbin to the traveler assumes a position with relation to the circumference of the bobbin more nearly the bobbin is being filled, for the spindle turns' at the same speed; but when the yarnisgbeing.

Wound on the bobbin, the latter being small, the draft onthe yarn is suiicienhand it acts to pull the traveler toward the then outer portion of the bobbin, which is then nearer the center of the ring than when the bobbin is mostly filled; and this inwarddraft, although insufficient to remove the inner end ofthe traveler from the race, does act to lessen the amount of its friction on the inner portion 'of' the race, making the friction :less than `when the yarn, proceeding from the full bobbin, acts on the traveler, for then the centrifugal action of the traveler, being less impeded,enables they traveler to bear at its inner end with greater -force than when Athe bobbin is first ,being Wound, and in this Way the draft on the yarnV and centrifugal action of the traveler tend to vmake the drag on the yarn and thewinding action more nearly uniform than is :the case with the ordinary ring and traveler, and va very light vtraveler may be used.

Ring-travel ers h ave frequently to be changed according to the size ofthe yarn or thread; but in all cases with aring and traveler constructed as above described, thevtraveler may be lighter than the traveler of van ordinary ring, for the drag on the yarn is evener, it1 being produced principally -by friction of both ends of the traveler against the ring or race, instead of by the Weight of the traveler, as heretofore common, and consequently a lighter traveler produces as much drag, and thedrag is more uniform, which enablesthe production of more even thread, and enables it to `be Wound closer.

ItL will be obvious that .thetraveler b, acted upon by the thread at or near the inner end Ofthbravelr,.n-stead @fatter nearfitscenter, n andnear .the topfof the Qrace, vvill move the y traveler with the greatest uniformity 4and with the least possible tendency to vibration.

When in action, the inner end of the travveler is ,held by the lthlfad and actionof ycentrifugal -force'against thefrace at a'point above `the point atyvhich .the outerendof the traveler meets the race. This ring may be made adjustableqon the .race through an ordinary holder. The race on this ring is arranged entirely outside of a line coinciding with the interior of the ring,and the traveler in action -moves ina circle of greater diameter than the diameter'of the interior portion of the ring, and this construction enables a bobbin to be wound full enough to fill the interior of the ring; but this inclined race may vmade nearerfthe centenof nthe .rin g Awithout departing from rthis invention.

II claim- 1. A spinning-ring, Yprovidedwith .an .outwardly-inclined race, shapedat itsinner side `,Substantiallyas .s.eft.forth, and with itsouter l edge lovverthan the innery edge, substantially as described.

2.l A .rin`gprovded with a race outwardly inclined, substantially as shown and described,

' in combinationwitha traveler adapted, owing to the actionof centrifugal force, to bear on and move withboth ends against the race, substantially as described.

3. As a newarticleI of manufacture, .aspin- 'ning-ring provided` with an outwardly-inclined circular raoe,the interior diameter of which is greater than-the smallestinterior diameter of the body ofthe ring, substan tially as described.

In testimony .whereof I have signed ,my name-to this yspecification in .the presenceof two subscribingwitnesses.
