RING TRAVELER.

Application filed August 16, 1923. Serial No. @57,815.

To all whom it may concern:

Be it known that I, MICHAEL J. SHnnu-mm a citizen of the United States, residing at New Bedford, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Ring Travelers; and I do hereby declare thefol lowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to, a novel form of ring traveler for spinning, and twisting machines and has for its object to provide a device of the character indicated which will reduce the friction between the traveler and the ring to a minimum, which will maintain a uniform tension on the thread, and which will deliver the thread to the bobbin, tube or other receiving element without impairing the nap on the thread, the device as a whole constituting a strong durable construction, capable of application to any of the standard types of spinning and twisting machines.

The invention is, illustrated in the accompanying drawing, in which Fig. 1 is an elevation of a single spindle of a spinning machine and its'associated ring, with the traveler applied thereto.

Fig. 2 is an enlarged elevation, the ring being shown in fragmentary section.

Fig. 3 is an elevation at right angles to that shownin Fig. 2.

Referring tothe drawing, 1 indicates a spindle of an ordinary splnning machine adapted to receive the usual bobbin or tube upon which the thread is laid up, as indicated at 2 Surrounding the spindle 1 is the usual ring 3, upon which the traveler, carrying the thread guide, rotates about the spindle.

The traveler comprises a body portion 10, generally elliptical in shape, having its lower side open, preferably made of flat spring steel, the ends and upper mid section of the body portion being ground or machined to form bearings for rollers 11, 11 and 12, the rollers 11 engaging the under side of the top flange of the ring and the roller 12 engaging the upper face of the ring, as more particularly shown in Fig. 2. In order to apply the roller 12 in position, it is preferably split longitudinally and the two halves are fitted over the bearing in the mid section of the body and secured Either formed as an integral part of, or

suitably connected to the body 10, is an arm13, preferably of spring steel, which extends upwardly from and over the body 10, terminating at its end in a loop oreye 14, in which is mounted a thimble or ferrule 15 of wear resisting material, such as porcelain, bakelite or the like, the arm and the eye on the end thereof constituting the thread guide, for directing the thread onto the bobbin or tube, as the traveler moves around the ring. v The particular advantage of employing a thimble of the character described in the eye of the thread guide, is the fact that neither the thimble nor the thread is impaired during a normal operation of the machine, as'there is practically no wear on the interior of the thimble and the thread passes through the thimble in engagement with the smooth surface thereof without suffering any abradi-ng action which would tend to rub the nan or loose fibre off the thread, whichis a very common and persistent objection to they use of thread guides in which the thread is brought directly in contact with a metallic surface.

In order to maintain a practically uniform tension on the thread, at all times, a helical spring 16 is interposed between the arm 13 and the body 10, preferably in the manner shown in Fig, 2, one end of the spring being connected to a small eye or arm 13 intermediate the length of the latter and the opposite end of said spring being secured to an eye on the body portion 10 of the traveler.

Experience has demonstrated that a traveler constructed and arranged as described, is capable of use with various sized threads, so that it is not necessary to supply a separate traveler for each particular size of thread. It has also been demonstrated, by practical application, that the traveler requires much less force to carry it around the ring and that the force required is pracis being laid up, and the properamount of tension may be accurately determined by the strength of the spring 16.

From the foregoing-description, it will be apparent that the traveler is highly eflicient in operation, in that it practically eliminates friction in its operation, insures a substantially uniform tension on the thread at all times, and completely avoids the. objectionable abrading ofthe thread, which tends to strip thenap therefrom. Furthermore, be-

- cause of thepeculiar structural form and arrangementof parts, the traveler is exceptionally durable and, as it is substantially immune from all of thewearing effects of the ordinary type of traveler, it will outlast the latter many times.

Also, within reasonable limits,':asingle traveler may be employed for various sized threads, thereby obviating thenecessity of applying a differ ent traveler for each diflerent size of thread.

' A VVha-t I claim is;

- wardly from and over said body, said arm tension spring having a ithread'guide'on its end, and a connected to said arm and body.

3. A travelerf for spinning and twisting machines comprising a body portion adaptedto engage a ring, an arm connected to one side of the body and extending upwardly from and over the body, the said arm having a thread 'guide'on its outer end, and a tensionspringconnectedto said arm intermediate the length of the latter and to the opposite side of the body.

4. A traveler for spinning and twisting machines comprising a body portion adapted to engage a ring, an arm extending upwardly from said body, said arm having a thread guide including a loop on the end of the arm and a thimble of wear resisting material within said loop, and a tension spring connected to said arm and body.

, 5. A traveler for spinning and twisting machines comprising a body portion adapted to engage a ring, an arm extending upwardly from said body, said arm having a thread guide including a loop on the end of the arm and a thimble of porcelain or the like within said loop, and a tension spring connected to said arm and body.

6. A traveler for spinning and twisting machines which comprises a body portion substantially elliptical in form having one side open, rollers journaled on the ends adjacent the open side and on the upper mid sectionof the body and adapted to engage the lower and upper surfaces of a ring, and an arm extending upwardly from said body said arm having a thread guide on its outer end.

7. A traveler for spinning and twisting machines which comprises a body portion of flat spring metal bent to substantially elliptical form open on one side and having reduced bearing sections formed on the ends adjacent the open side and on the upper mid section, rollers journaled on said bearin sections adapted to engage the lower an upper surfaces of a ring, and an arm extending upwardly from said body said arm having a thread guide on its outer end.

In testimony whereof I afiix my signature.

MICHAEL J. SHEEHAN.
