Y., assignor to U. S. Ring Traveler Company, Providence, R. I. , a corporation of Rhode Island Application October 4, 1937, Serial No. 167,294 5 Claims. This invention relates to improvements in ring travelers, and particularly of the vertical type of travelers adapted for use in twisting machines, and of such construction as will avoid and over come objections to ring travelers heretofore in general use. The present invention relates to a traveler for use in twisting machines and in the handling of various kinds of yarn. Prior to the development 10 of the present traveler the usual type of vertical traveler was made with the two ends, or horn and foot portions, at substantially a 90° angle with the body or shank or back of the traveler. Such a traveler in use lies at an angle such that the top of the traveler leads the bottom of the traveler in revolving around the ring. Traveling in this fashion at considerable velocity the tend ency is for the air to pushdown on the top of the traveler and hold down on the bottom of the 20 traveler with the net result that the entire trav eler is forced downwardly by the air. In the case of o?set travelers heretofore in use the top or horn and bottom oi.’ the travelers are bent at such an angle to the body of the trav eler that said portions are substantially parallel to the upper and lower edges of the ring while the traveler is in use. In the use of a traveler of this nature there would be normally no air pressure causing either a lift or a downward push on the traveler. The present invention relates to an improve ment in a traveler wherein the horn or top of the traveler is bent at an angle greater than the angle at which the traveler lies in use, that is, wherein the forward edge of the horn is at an angle to the rear edge forming in effect a pocket wherein the air is caught under such top portion with the result that as the traveler moves around on the ring the air pressure on the inner face 40 of the horn will tend to lift the traveler upwardly away from the ring against the force of gravity which normally would hold the traveler down on the ring. One form of my invention is shown in the ac companying drawing wherein corresponding nu merals of reference indicate corresponding parts in the several views, and in which:— Fig. 1 is a rear perspective View of my inven tion showing its use on a vertical twister ring; Fig. 2 is a fragmentary view of a ring with a rear view of the traveler mounted thereon; Fig. 3 is a section on the line 3—3 of Fig. 2; and Fig. 4 is a fragmentary view of the ring, in front elevation, with a traveler mounted thereon. (Cl. 118-61) In the drawing, I0 designates a vertical twister ring in the rail ll, of a twister frame, of any usual construction, wherein the ring has recip rocating vertical movement in the direction of the arrows shown in Fig. 1. In this ?gure there 5 is also shown a portion l2 of the yarn or thread which is delivered to the traveler l3 from the usual delivery rolls and which passes from the traveler to the spool or bobbin on which the yarn is being wound. 10 The present traveler, as shown in perspective in Fig. 1, comprises a foot portion I4 which en compasses the lower edge of the ring In and is substantially parallel thereto, the outer end of this foot portion being bent upwardly as at I5 in 15 the usual manner. This traveler has a shank portion l6 which extends upwardly and inwardly as at I‘! to a point l8 where it merges with the horn or top portion l9 of the traveler. Said horn or top portion l9 extends on its rear or trailing edge from the point l8 substantially out wardly on a line parallel with the bottom foot portion. From the front or leading edge '20 of the horn portion the top portion [9 extends out wardly and upwardly at an angle to the rear edge 25 and the horn portion terminates in a portion 2| bent sharply downward, thus forming in effect a pocket 22 for the air; the air pressure against the under surface of the horn, as indicated by the arrow in Fig. 1, causing the lifting or ele- 30 vating of the traveler and raising of the same against the force of gravity when the traveler is revolving around the ring. The main feature of the present traveler is the provision of a horn portion of this character such 35 that the air is caused to contact with the under surface of the horn portion and the traveler is thereby always held in position on the ring with the horn portion above and free of the ring, while in 1186. 40 The advantages: in the use of such a traveler will be obvious from the opening statement here in and. it will be readily seen that in operation the traveler is held, as shown in all of the ?gures, with the upper end of the shank of the traveler 45 ' ' and the horn portion above and away from the upper edge of the ring, whereby a. pocket is pro vided such that the air is directed against the under face of the. horn or head portion, holding the same away from the upper edge of the ring 50 r and obviously avoiding any tendency of the yarn becoming soiled by reason of grease or oil from the traveler. It will also be seen that in the use of the present traveler considerable friction is avoided in that in use no portion of the horn or 55 2 2,108,027 3.
