GUIDE FOR YARN CARRIERS Original Filed Nov. 4, 1948 v INVENTOR. EDWARD JENTSCH aw J M ATTORNEYS United States Patent Ofiice 2,694,303 Patented Nov. 16, 1954 GUIDE FOR YARN CARRIERS Edward Jentsch, Clifton, N. J.

Original application November 4, 1948, Serial No. 58,267, now Patent No. 2,656,692, dated October 27, 1953. Divided and this application September 2, 1953, Serial No. 378,071

6 Claims. (Cl. 66-126) The present invention relates to new and useful improvements in yarn carriers and relates more particularly to a yarn carrier wherein the thread is supported in spaced relation to the carrier on removable elements.

The present application is a division of my copending application Serial No. 58,267 filed November 4, 1948 for Guide for Yarn Carrier, now Patent No. 2,656,692.

In the past whenever the portions of a yarn carrier over which a thread ran became worn by reason of the continuous movement of the thread over the carrier or were otherwise damaged, it was necessary to discard the entire yarn carrier and replace it with an entire new carrier which was both expensive and wasteful. The present invention is directed to providing a yarn carrier with thread supporting and guiding means of wear resistant material that hold the thread away from the surface of the carrier itself to prevent wear on the carrier and which are removably secured to the carrier so that they may be replaced upon becoming worn or otherwise damaged. The various objects and advantages of my invention will be apparent and best understood from the following description and the accompanying drawings in which:

Fig. 1 is a perspective view of a portion of a yarn carrier embodying my invention;

Fig. 2 is a plan view of a portion of the carrier with the thread guide as illustrated in Fig. 1;

Fig. 3 is an end view in partial section of carrier and thread guide illustrated in Fig. 2;

Fig. 4 is a plan view of a modified form of thread guide embodying the invention;

Fig. 5 is an end view in partial section of the thread guide illustrated in Fig. 4;

Fig. 6 is a plan view of another form of thread guide embodying the invention;

Fig. 8 is a plan view of another form of thread guide embodying the invention; and

Fig. 9 is an end view in partial section of the thread guide illustrated in Fig. 8.

Referring now to the drawings in detail there is a yarn carrier 1 of a type suitable for use in full fashioned hosiery machines. It will be understood, of course, that the present invention is not limited to a particular type of yarn carrier, but may be applied to various types of yarn carriers.

The carrier 1 may be provided with one or more thread guides, designated generally by the number 2 in Fig. l. The thread guide 2 directs a thread 3 in its movement over the carrier to a suitable thread-guide tube 4 that is held between spring-jaws at the end of the carrier. The thread guide 2, as illustrated in Figs. 1-3, has a U -s haped support member 5 that is secured in inverted posltion on the carrier 1. The support 5 projects from the surface of the carrier 1 with the legs of the support 5 definmg a passageway 6 through which the thread may pass as it moves across the carrier to a delivery po nt and the passageway 6 will serve to direct the thread in its movement across the carrier.

The U-shaped support 5 has outwardly pro ecting shoulders that extend over and engage with portions of a circular thread-supporting member 7. The thread-supporting member 7 is made of wear resisting materlal, such as a hardened steel wire that is resiliently deformable and is removably secured to the carrier by the support 5. The thread 3 in its movement across the carrier and through the support 5 rests on the thread-supporting member 7 and is held in spaced relation to the surface of the carrier. Thus, any wear due to the movement of the thread across the carrier takes place on the threadsupporting member 7 rather than on the surface of the carrier. The top of the support 5 may be sloped downwardly so that the thread-supporting member 7 may be forced downwardly over the top of the support 5 and is deformed sufficiently in this manner to permit portions of the thread-supporting member to be engaged beneath the shoulders of the support 5. The thread-supporting member 7 may be easily removed from the support 5 by deforming the ring with a pair of pliers to a shape that will permit the member 7 to pass over the shoulders of the support 5. I

In addition to supporting the thread 3 and holding the thread away from the surface of the carrier 1 so as to prevent wear on the carrier, the ring 7 also reduces the area of the carrier contacting with the thread and consequently reduces the frictional drag on the thread 3 as it moves across the carrier. This makes it possible to guide the thread more easily and accurately and with reduced breakage.

In the form of the invention illustrated in Figs. 4 and 5, there is a U-shaped support 8 that is carried by the carnor 1 in an upright position. A circular, thread-supporting member 9 is removably held between the legs of the U-shaped support 8. The thread-supporting member 9 is made of wear resisting material and the thread 3 runs through a central opening in the thread-supporting member 9. Thus, the thread-supporting member 9 directs the thread and holds the thread in spaced relation to the surface of the carrier. The opposed surfaces of the legs of the U-shaped support 8 may be shaped to prevent lateral displacement of the thread-supporting member 9 when it is wedged between them.

In the form of the thread guide illustrated in Figs. 6 and 7, there is a supporting member 10 that has a passageway or opening 11 through which the thread 3 passes. As the thread 3 passes through the passageway 11, it runs over a thread-supporting member in the form of a wire clip 12 of wear resistant material. The ends of the wire clip 12 are fitted into openings in the sides of the support 10 to hold the wire clip in place on the carrier and the wire clip 12 may be readily removed or replaced by spreading the ends of the clip 12 and moving it onto or off of the support 10.

In the form of the thread guide illustrated in Figs. 8 and 9, there is a supporting member 13 that has a passageway or opening 14 through which the thread 3 passes. A thread-supporting member in the form of a rod 15 of wear resistant material extends through the legs of the support 13 and across the bottom of the passageway 14 in the support. The rod 15 is removably held in the legs of the support 13 and may be removed for replacement by sliding it out of the legs of the support 13.

The supports to which the replaceable thread-support-- ing members are removably secured may also be removably secured to the carrier, if desired, and in such case the thread-supporting member may be made a part of the support and removed with it. It will be noted, however, that in any case, the thread-supporting member is removable from portions of the thread guide 2 with the carrier and may be replaced without discarding the entire carrier since such members become worn from the movement of the thread 3 across the carrier and require frequent re-' placement.

It will be apparent that those skilled in the art may make various changes and modifications in the embodiments of my invention as illustrated and described herein without departing from the scope of the claims as appended hereto.

I claim:
