July 28, 1931. .G. H. GILLIGAN RING TRAVELER Filed Dec. 10, 1930 Patented July 28, 1931 UNITED STATES ISLAND OFFICE j GEORGE H. GILLIGAN, or PROVIDENCE, RrionE ISLAND, ASSIGNOR mo U. s. RING TRAVELER COMPANY, or PROVIDENCE, RHODE ISLAND, ,A- CORPORATION or RHoDE RING TR vELER' Application filed December 10,1930. Serial No. 501,208.

My invention relates to' ring travelers of the horizontal or bow type for use upon spin ning or twisting rings. V

In this type of traveler the body isarched and terminates at its lower end with horizontally inwardly directed aligned horns at their free ends.

The material for the travelers is automatically cut in length from a metallic strip or rod, and subsequently bent, hardened and polished. The cutting or severing operation leaves the blanks with rough or wire edge terminal faces, which even the final step of polishing frequently fails to eliminate.

] In the final product the roughness appears at the free ends of the horns which are presented to the ring web as the traveler rides around the ring, and cutting or scoring of the web occurs along a line of continuous contact, and the traveler itself becomes worn, which results in expense by reason of replacements and stoppages.

the ends of the traveler are successfully This wear is very pronounced even when smoothed, and at best present relatively sharp or penetrating projections to the ring web.

The essential objects of my invention are to overcome the disadvantages above adverted to, prevent the scoring of the ring by the traveler, assist maintaining the traveler in upright running position, and to effect the desired objects in a simple and inexpensive structure.

To the above ends essentially my'invention consists in such parts and in such combinations of parts as fall within the scope of the appended claims. f

In the accompanying a part of this specification,

Figure 1 is a plan of a spinning or twisting ring engaged'by my novel traveler,

Figure 2, a fragmentary sectional view of the same taken on line 22 of Figure 1, V

Figure 3, a perspective view of my traveler detached, and

' vIt is in conjunction with a ring having drawings which form.

detail vie'w of a modified form 'As herein shown 7 represents a ring of the horizontal type commonly employed upon spinning andfltwisting machines, and comprises a vertical body or web 8, a base 9, and a horizontal top flange 10 extending laterally of both faces ofthe web. 1

the type of flange 10 herein above set forth that my traveler 12 is intended to be employed.

The latter is bent up from a substantially flatmetallic blank, and comprises an arched body or bow 13, horizontal horns 14, and terminal bearing member s. consisting of fingers l5, continuous with the free ends of the horns, directed toward the bow, and disposed at substantially right angles to the latter. The bearing faces of the fingers are indicated at 16.

In Figure 2 the traveler is shown applied I to the ring in an operating position. Centrifugal force, during movement of the they web 8, at the point where the impinging power is greatest. ,Under these conditions also the parallel relation of the contacting fingers 15 to the web; tends toassist maintaining the traveler 12 in a horizontal rather than tilting position relatively to the ring.

It will be noted that the presence of the members 15 renders impossible the scoring of' the ring which centrifugal action would occasion were they absent.

In the modification of my,invention shown in Figure '5 the terminal edges 23 of the bearing members or fingers are transversely curved.

Having thus described certain illustrative embodiments of my invention, it is understood 1 that the specific terms employed are used in a descriptive sense only, and are not'for the stantially right angles to the horns and di rected toward the bow providing a flat bearing surface for the traveler.

2. In combination with the web and flange of a spinning or twisting ring, a ring traveler comprising a bow spanning the ring, horns upon the bow extending towards the web,

and terminal bearing members upon the horns disposed at substantially right angles towsthe horns andvdirectedvtoward the bow, providing a fla t bearing surface for the traveler with the web.

3. A ring traveler comprising a bow i nwardly directed horns upon the ends of the bow, flat bearing members continuous with the ends of the horns extending at substantially right angles to the horns and vertically directed toward thebow.

4..A ring traveler comprising a bow, inwardly directedhorns upon the bow, terminal bearingmembers upon the horns disposed at substantially right angles to the horns and directed toward the bow, providing a flat bearing surface for the traveler, the terminalaedgessof the: bearing members being curved transversely.

In testimony whereof I have aflixed my signature.

GEORGE H. GILLIGAN.
