TRAVELER WITH MAXIMUM DIAMETER WEAR RESISTANT INSERT Filed June 30, 1964 INVENTORA Lou/5 H Mam/v HTTOR/VEY United States Patent 3,302,383 TRAVELER WITH MAXIMUM DIAMETER WEAR RESISTANT INSERT Louis H. Morin, Bronx, N.Y., assignor to Coats & Clark Inc., New York, N.Y., a corporation of Delaware Filed June 30, 1964, Ser. No. 379,272 1 Claim. (Cl. 57-125) This invention relates to travelers formed of plastic material and incorporating in the juncture of the hook end with the shank end of the traveler a tubular wearresistant member or insert, having flared ends providing between the juncture of said hook and shank parts a maximum diameter thread or yarn engaging wear resistant surface. More particularly, the invention deals with a traveler of the character defined, wherein that part of the molded body of the traveler arranged within said member or insert is substantially of reel formation to provide a strong coupling between the otherwise relatively thin or lightweight hook and shank parts.

Still more particularly, the invention deals in a traveler structure, wherein the adjacent spaced portions of the hook and shank parts terminate in disc-like members fully enveloping terminal ends of said wear resistant member or insert.

The novel features of the invention will be best understood from the following description, when taken together with the accompanying drawing, in which certain embodiments of the invention are disclosed and, in which, the separate parts are designated by suitable reference characters in each of the views and, in which:

FIG. 1 is an enlarged side view of the large hook end portion of a molded plastic traveler, illustrating the wear resistant member at the juncture of the hook and shank parts of the traveler.

FIG. 2 is a view looking generally in the direction of the arrow 2 of FIG. 1, with parts of the construction broken away and parts shown in section; and

FIG. 3 is a view looking generally in the direction of the arrow 3 of FIG. 1, with parts of the structure broken away and with part in section.

The present invention deals with the formation of molded plastic travelers having tubular-type wear resistant members or inserts.

In illustrating one adaptation and use of my invention, I have shown in FIG. 1 in the accompanying drawing a molded plastic traveler body 10. At 11 is shown one end portion of the shank part of the traveler body, namely that end with which the large hook part 12 is united through the medium of an integral bridging part 13, generally of reel formation. The part 13 forms the backing and support for a wear resistant member or insert 14, the latter being in the form of a tubular body having flared ends 15 and 16 arranged upon the flared sides 17 and 18 of the bridging part 13, as clearly illustrated, in part, in FIG. 2 of the drawing. The terminal ends 19 and 20 of the member 14 terminate in and are fully enveloped by disc- like ends 21, 22 on the shank part 11 and hook part 12 where these parts integrally join the reel part 13, again, as clearly illustrated in the sectional portion of FIG. 2.

Considering FIGS. 2 and 3 of the drawing, it will appear that the width or transverse dimensions of the shank part 11 and hook part 12 are materially less than the smallest diameter of the reel part 13. Thus, said reel part 13, in addition to forming a. substantial backing for the member 14, also provides a reinforced coupling or bridging member between the parts 11 and 12, the latter being further amplified by the discs 21 and 22 which envelop the terminal ends 19 and 20 of the member 14. At the same time, the metallic wear resistant member 14 serves to also reinforce the coupling between the shank part 11 and the hook part 12.

It will be apparent, from a consideration of FIGS. 1 and 2 of the drawing, that the wear resistant member or insert 14 provides a maximum diameter wear resistance between the disc ends 21 and 22, thereby creating a larger radial arc of contact of the thread or yarn operating upon the member 14, resulting in a longer life use of the traveler.

The tubular wear resistant member or insert is generally of hourglass cross-sectional contour and the entire peripheral surface of said member is exposed between inner surfaces of the disc- like ends 21 and 22, as will be clearly apparent from a consideration of FIGS. 1 and 2. It will also be noted that outer and inner edge surfaces of the shank part and hook part extend to and register with the largest diameter of the ends of the member 14. However, portions of the material of the disc- like ends 21 and 22 overlie the terminal ends 19 and 20, as clearly noted in the sectional portion of FIG. 2 of the drawing.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:

A molded plastic traveler having a hook part, a shank part, an integral hour glass shaped bridging part uniting said hook and shank parts, a thin walled tubular wear resistant member immovably encircling the bridging part, flared sides on the bridging part, flared ends on said member arranged upon said flared sides, the maximum diameters of said member and said flared sides being substantially the same, the shank and hook parts, where they integrally join the bridging part, including disc-like ends, and said disc-like ends enevioping the terminal ends of said wear resistant member.
