' RING TRAVELER Filed 001;. 4, 1937 Patented F ch. 8, 1938 UNITED STATES PATENT OFFICE RING TRAVELER Sam Tour, New York, N. Y., assignor to U. S. Ring Traveler Company, Providence, R. I. a

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 overcome 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 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 tendency is for the air to pushdown on the top of the traveler and hold down on the bottom of the traveler with the net result that the entire traveler is forced downwardly by the air.

In the case of ofiset travelers heretofore in use the top or horn and bottom oi. the travelers are bent at such an angle to the body of the traveler 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 improvement 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 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 accompanying drawing wherein corresponding numerals of reference indicate corresponding parts in the several views, and in which:-

Fig. 1 is a rear perspective View of my invention 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 33 of Fig. 2; and

Fig. 4 is a fragmentary view of the ring, in front elevation, with a traveler mounted thereon.

In the drawing, I designates a vertical twister ring in the rail ll, of a twister frame, of any usual construction, wherein the ring has reciprocating vertical movement in the direction of the arrows shown in Fig. 1. In this figure 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.

The present traveler, as shown in perspective in Fig. 1, comprises a foot portion I4 which encompasses 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 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 outwardly 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 outwardly and upwardly at an angle to the rear edge 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 elevating 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 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.

The advantages: in the use of such a traveler will be obvious from the opening statement herein and. it will be readily seen that in operation the traveler is held, as shown in all of the figures,

with the upper end of the shank of the traveler and the horn portion above and away from the upper edge of the ring, whereby a. pocket is provided 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 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 5 top of the traveler contacts with the ring, the same being held by the pressure of the air away from the upper edge of the ring.

The present traveler, in use, due to the elevation thereof by the air pressure under the top of the traveler insures a minimum of friction and eliminates excessive ring and traveler wear present in a number of travelers heretofore in use which contact at some point the upper edge of the ring.

With the foregoing and other objects in view the present invention consists of an improved construction in air lift travelers which will be more fully described and particularly pointed out in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of. the United States, is:--

1. A ring traveler for vertical twister rings, formed with a foot, a shank extending upwardly therefrom and merging into a head or horn portion, the head or horn portion extending outwardly and upwardly from the shank at its leading edge and substantially horizontally at its trailing edge, thereby forming a pocket whereby the air in the operation of the traveler contacts with the under surface of said horn portion.

2. A ring traveler for vertical twister rings, formed with a foot, a shank portion, a foot portion extending at substantially right angles outwardly from the shank, and a head or horn portion, extending outwardly and upwardly from. the shank portion at its leading edge and substantially horizontally at its trailing edge and thereby forming a pocket whereby in the revolution of the traveler the air pressure against the under surface of said horn portion lifts or elevates said traveler.

edge of the foot, the head 3. A ring traveler for vertical twister rings, formed with a foot, a shank extending upwardly therefrom and merging into a head or horn portion, the inner edge of the shank portion being substantially parallel with the corresponding portion extending outwardly from the shank with its trailing edge substantially at right angles to the shank and its leading edge at an obtuse angle thereto, thereby forming a pocket whereby air contacting the under surface of the horn when in operation causes the traveler to be lifted away from the upper edge of the ring.

4. A ring traveler for twister rings, formed with a foot, a shank extending upwardly therefrom and merging into a horn or top portion, the foot extending outwardly at substantially a right angle to the shank portion and the leading edge of the horn extending outwardly and upwardly at an angle to the shank portion and the trailing edge extending outwardly substantially horizontally.

5. A ring traveler for twister rings, formed with a foot, a shank extending upwardly therefrom and merging into a horn or top portion, the foot extending outwardly at substantially a right angle to the shank, and the horn extending outwardly and upwardly at its leading edge at substantially an obtuse angle and at its trailing edge at substantially a right angle, whereby a pocket is formed and the air contacting the under surface of the horn during the operation of the traveler is caused to lift the same away from the upper edge of the ring.
