SPECIFICATION forming part of Letters Patent No. 772,527, dated October 18, 1904.

Application filed September 23, 1903. Serial No. 174,301. (No model.)

To (tZZ whom, it may concern.-

Be it known that I, LEMUEL MELLETT," a citizen ofthe United States, residing in Somerville, in-the county of Middlesex and State of Massachusetts,have invented an Improvement in Travelers for Spinning-Rings, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to spinning and twistv ing machines,'and more particularly to the traveler employed in connection therewith. In machines of the class described and known to me the-traveler is usually made of steel and fits loosely over a ring, the said traveler being made substantially semicircular in shape and provided with inturned ends which extend, under the upper part or head of the ring. In practice the traveler is revolved at a high speed, usually from eight to ten thousand revolutions per minute. The traveler when at rest occupies a position radially with relation to or substantially at right angles to its path of movement; but in operation the thread cants the traveler with relation to its path of movement, so that it does not remain substantially at right angles thereto, but is moved into a position which is inclined with relation to said path of movement, in which position one end of the inner inturned end or flange on the traveler is broughtnearer to the ring than the opposite end of said flange, so that when the traveler is moving at a high speed centrifugal action moves the traveler outward and brings the rear end of the inner flange or inturned portion of the traveler into contact with the ring, thereby creating friction, which results in imposing a drag or brake on the traveler and consequent strain on the thread and also unduly heats the contacting end of the inturned flange on the traveler, which renders the latter so brittle as to befrequently broken, thereby rendering the traveler useless. So,

also, the contacting end of the inturned edge of the traveler frequently cuts or digs into the side of the ring, which renders the ring imperfect and frequently useless.

The present invention has for its object to provide a traveler with which the above-noted objections or defects are overcome and with which a higher speed may be obtained without breaking the thread. In accordance with this invention the traveler is constructed so as to offer a'resistance' to the'air on the outer side of the traveler, whereby the action oftravelersh'own in Fig. 3; Fig. 5, a plan view of the traveler shown in Fig. 3 inverted; Fig. 6 a plan view of a spinning-ring with a modified form of traveler; and Fig. 7, a cross section on the line 7 7 Fig. 6.

Referring to the drawings,'a represents a spinning ring such as now commonly employed and upon which ismounted to move thereon a traveler embodying this invention.

The traveler referred to may and preferably will be made as shown in Figs. 3 to 5, inclusive, and consists of a band-strip or body portion 6, provided with inturned ends or flanges c d, which may be designated, respectively, the inner and outer ends or flanges. In accordance with this invention the outer flange d is extended at an angle to the body portion 6 so as to form a traveler which is wider at its rear than at its front side and is provided with an outwardly -'inclined outer side. The inner flange 0 may also be inclined with relation to the strip or band I); but good results may be obtained with the inner flange substantially parallel with the body portion 6.

By reference to Fig. 1 it will be seen that the thread 6 passed under the traveler has a tendency under tension to cant or turn the traveler from a radial position with relation to the ring to one at an angle to said ring, which has the eifect of bringing the rear end 10 of the inner flange nearer the web 12 of the ring a, so that when the traveler is revolved at a high speed said rear end is brought into contact with the inner surface of the web 12 under the influence of centrifugal action; but by reason of the outer flange extending outwardly, as represented, a substantial area of surface on the outer side of the traveler is oifered to the air, which, as the traveler revolves at a high speed, exerts a pressure on the outer surface of the traveler and moves the same in opposition to centrifugal action, thereby keeping the inner flange of the traveler free from the spinning-ring and enabling the traveler to be revolved at an increased speed without injury to the traveler and ring and without breaking the thread. In other words, the outwardly-inclined outer surface of the traveler offers a greater resistance to the movement of the traveler than the inner surface of the same, which resistance is utiliZed to move the traveler toward or into the normal radial position with relation to the spinning ring, and thus remove the inner flange from engagement with the inner side of the ring, and thereby overcome the defects and objections above noted and inherent in travelers as now commonly constructed.

I may prefer to construct the traveler as shown in Figs. 1 to 5, inclusive; but I do not .desire to limit my invention in this respect,

as good results may be obtained with the travelers as now commonly made by providing their outer sides or flanges with an air-resisting surface, which may be made in the form of a fixed or stationary wing or projection 15 on the outer side of the traveler, as shown in Figs. 6 and 7.

I claim 1. A traveler for spinning-rings consisting of a body portion adapted to extend over the spinning-ring and inturned ends or flanges attached to said body portion and extended at an angle thereto toward each other and away from the same edge or side of the said body portion, substantially as described.

2. A traveler for spinning-rings consisting of a body portion adapted to extend over the spinning-ring and provided with inturned ends or flanges, the outer flange extending outwardly at an angle to said body portion to form a traveler wider at its rear than at its front side, substantially as described.

3. A traveler for spinning-rings consisting of a body portion adapted to extend over the spinning-ring and provided with inner and outer inturned ends or flanges, said outer flange having provision which is lixed with relation to said body portion for effecting movement of the traveler in opposition to centrifugal action to keep the inner flange of the traveler out of contact with the ring, substantially as described.

4. The combination with a spinning-ring, of a traveler mounted thereon and provided on the outer side of the spinning-ring with stationary or fixed means for offering a greater resistance to the air than on the inner side of said ring, substantially as described.

5. A traveler for spinning-rings provided with a body portion and with an air-resisting surface on its outer side extended at an angle to said body portion and having a iixed or stationary relation to said body portion.

6. A traveler for spinning-rings provided on its outer side with a fixed or stationary surface to ofler a resistance to the air and ciiect movement of the traveler in operation in opposition to centrifugal action, substantially as described.

7. Atraveler for spinning-rings consisting of a body portion adapted to extend over the spinning-ring and converging inturned ends or flanges attached to said body portion, for the purpose specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
