' This invention relates to a spinning ring traveler such as used in ring-spinning and twisting in the textile industry and has for its purpose to provide a traveler that has a longer life than previously known types and is not affected as to wear by friction imposed by the strands of yarns or threads as they move in contact with the traveler.
Travelers for the purpose have in the past been made from metal, "principally bronze, and from linear condensation polymers such as nylon," and it is a particular purpose of the invention to provide a traveler with a hard abrasion-resistant insert covering the surface that is contacted by the strands or threads, the abrasion-resistant insert being interlocked with the body of the traveler and rigidly attached thereto, with a formation such as to make possible a rigid permanent union with the traveler and to provide a properly shaped strand-engaging surface that takes the wear and protectsthe body of the metal or nylon traveler from direct contact with the strand. I A more particular object of the invention is to afford a hard abrasion-resistant insert of firehardened material of such shape and construction as to insure interlocking against relative lateral movement while reducing to a minimum the friction between the strand and traveler as the strand moves in contact therewith. a I
To these and'other ends, the inventionconsists in the construction and arrangement that will appear clearly from the following description when read in conjunction with the accompanying drawings, the novel features being pointed out in the claims following the specification.
In the drawings: I Fig. l is a view in side elevation of a traveler made from nylon and provided with an interlocked and rigidly attached strand-engaging insert of abrasion-resistant fire-hardened material, accordance with a preferred embodiment of the invention; d J
" Fig. 2 is a side elevation of the same;
" "Fig. 3 is an enlarged detail sectional view taken on line 3-3 of Fig. l; 1

".R eferring more particularly to the drawings in which like reference numerals refer to the same parts throughout the severalviews; the invention 11 Claims. (Cl. 57-125) taken is applicable to a "nylon or similar traveler as disclosed in Patent No. 2,326,828, or tea bronze or other metal traveler, as conventionally employed in the textile industry in connection with spinning and twisting machines, and embodies a wear surface consisting of an insert of extremely hard wear-resistantfire-hardened refractory material interlocked with and rigidly attached to the traveler, and having a form that insures permanent integral connection with the traveler and reduces to a minimum the friction between the traveler and the yarn or thread moving in contact therewith, While eliminating appreciable wear on the traveler, and this is accomplished in the case of the nylon traveler by molding the insert into the traveler, utilizing an insert of the form illustrated in Figs. 1 to 3 inclusive.
For this purpose, an insert of hard wear-resistant fire-hardened material such as disclosed in Patent No. 2,463,979, March 8, 1949, is employed, although any other material of suitable refractory character may be used. The insert includes a body that has a concave surface transversely, as indicated at I, Fig. 1, and a convex surface laterally or in a plane perpendicular to the plane of Fig. 1, as indicated at 2, Fig. 2. The numeral 3 designates a groove formed in the hard abrasionresistant insert extending around the under surface of the hook portion. The traveler which is formed of a linear condensation polymer such as nylon includes a hook portion G that is molded around the wear-resistant insert, forming an interlocking connection with the groove 3 which is thus embedded in the nylon, as shown in Fig. 2, and'when thus molded into place, the concave transverse surface I. of the insert forms a continuation of the adjacent under surfaces of the traveler, the insert being relatively thick at its central portion and including'ta'pering sides of gradually reducing thickness, as indicated at 5, the outer surfaces of which merge into the-adjacent outer surfacesof the traveler. -The numeral 6 designates a boss-or projection formed on the insert and'embedded in the molded nylon, acting to prevent relativeimovement of the insert transversely of the traveler.
With this construction and arrangement, the
wear-resistant insert is rigidly secured to the traveler, being anchored against relative movement in any direction, and affords a thick central surface 2 ata point approximately centrally or adjacent to the center of the concave surface I.
The insert is so formed that when united to thetraveler, it merges into the adjacent surfaces of the traveler and forms continuations of the under and side surfaces of the traveler, whereby the strand as it is drawn through .the traveler in contact with the wear-resistant surface is always in contact with such surface and is effectively prevented from contacting the body of the traveler at any part thereof.
The invention oe likewise incorporated in a bronze or other metal traveler including a hook portion at its upper end of substantially rectangular cross-section, -to the under surface of which is applied a wear-resistant element of any suitable refractory or other hard material that is fire-hardened, such wear-resistant insert including a thickened portion 8 at itscenter and tapering portions Q at its sides of gradually reducing thickness. The insert also has a bottom surface ll that is concave transversely and of convex formation laterally as shown at i2 in .a plane perpendicularto the plane of Fig. i. The upper surface of the insert is of convex formation to conform .to the hook portion 2' and provided with a circumferential groove 53 that receives the curved hook portion 1 seated therein .andvis thereby held against relative lateral rnovement. The wear-resistant insert fits somewhat tightly into the slightly resilient hook portion which retains the insert by a compressing or spring action after the insert is forced into operative position within the traveler, where it is securely held against lateral movement by the side walls l t-of the insert that extend to the top of the hook portion of the traveler seated therebetween. In order to prevent relative .endwise -or transverse movement between the insert and traveler, or possibility of loosening, a body of solder or other suitable adhesive material is applied bet veen the adjacent surfaces of the insert and traveler as indicated at 55.
While the invention has been described with .reference to the-particular structure shown here- .in, it is-not confined to the details'disclosed, and this application is intended to cover such modifications or departures as may comewithin the purposes of the improvement or the scope of the following claims.
