J. P. KING 7 YARN GUIDE FOR BRAIDER CARRIERS Filed Dec. 21, 1945 IQVENTOR Ma v ATTORNEYS Patented Mar. 9, 1948 UNITED STATES PATENT OFFICE YARN GUIDE FOR BRAIDER CARRIERS John P. King, Pawtucket, R. I.,.assignor to Smith- King Company, a corporation of Rhode Island Application December 21, 1945, Serial No. 636,374

2 Claims. 1'

This invention relates to a device for handlin yarn in the textile industry, one example of which may be a braider carrier for use on braiding machines, as shown in my Patent No. 2,258,018, dated October 7, 1941.

In the use of yarns having a, high abrasive character such for instance as yarn formed of glass or nylon, it is found that the guide through which the yarn operates becomes worn to such an extent that its replacement isnecessary; and usually the part upon which the yarn guide is formed must be completely replaced as the yarn guide is an integral part thereof, it being necessary that the yarn guide and the part which supports it be firmly and rigidly attached.

One of the objects of this invention is to provide a yarn guide which is separably connected, although rigidly connected, to the part upon which it is mounted which yarn guide may be removed if it is worn and replaced by a fresh yarn guide in a simple and quick operation.

Another object of the invention is to provide a yarn guide which is resiliently attached or which has a resilient jaw for gripping the part upon which it is mounted whereby the yarn guide may be sprung from supported position and removed by merely pressing the fresh yarn guide onto the support on which it is mounted.

Another object of the invention is to provide a replaceable thread guide which need use no rivet for attachment.

Another object of the invention is to arrange a thread guide and its support so that the thread will continually tend to pull it onto its support.

With these and other objects in View, the invention consists of certain novel features of construction, as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings:

Fig. l is a side elevation illustrating a braider carrier with certain parts omitted but illustrating the sliding weight with my improved yarn guide attached thereto.

Fig. 2 is a perspective view of this weight, detached from the carrier and illustrating my yarn guide in assembled position therewith.

Fig. 3 is a perspective view of the weight alone.

Fig. 4 is a perspective view of the thread guide alone.

Fig. 5 is a sectional view on line 5-5 of Fig. 1 with the parts below the section omitted.

Fig. 6 is a central sectional view through the thread guide and support.

Fig. 7 is a fragmental elevation of the thread guide support.

2. Fig. 8 is a view similar to Fig. 6 showing a modification.

In proceeding with the. part with which the thread guide is assembled. to which this thread. guide is attached. by

springing the jaws into position. Interlocking. means are provided for preventingrocking oflthe thread guide when in such position.

With reference to the drawings, 10 designates generally a braider carrier as shown more fully in my Patent No. 2,258,018 having a base Il, yarn package spindle l2 and a weight guide post. 13 upon which there is mounted the weight which. maintains a tension on thread l5 shown by the dash-dot line as leading from the package not shown beneath the thread guide I6, and thence up through the pig-tail guide 9 at the top of post [3. This thread guide serves to direct the path of the thread in connection with the tension weight M which slides up and down along the post 13 to maintain a proper tension upon the thread. This weight operates a latch for releasing thread from the yarn package in the usual manner which, as it forms no part of this invention, is not shown.

The weight, designated generally I4, is provided with a support ll extending outwardly from a portion of the body thereof and is provided with a rib l8 extending longitudinally of the weight. This support serves for the mounting of the thread guide, designated generally [6 and shown in perspective in Fig. 4, and in section in Fig. 6.

This thread guide has a hook 19 formed by stock doubled upon itself, causing arms 20 and 2| to be in spaced relation while the resilient arm 22 extends upwardly generally parallel to portion 20 and is resilient to an extent to provide gripping jaws between the

parts

20 and 22. The arm 22 is provided with an inwardly extending rib 23 extending a portion of the length thereof (see Fig. 6) which fits the concavity of the rib I8 in the support l1 while the portion 2a of the guide I9 is also provided with a concavity 24 to fit the other surface of the rib l8 on this support. This concavity 24 provides a rib 25 extending inwardly of the hook and following about the hook into the arm 2| as shown more clearly in Figs. 4 and 6.

This ribbed formation extending centrally of this guide serves not only to prevent rocking of the guide when in assembled position on the support I! but also serves to materially stiffen the. parts of the guide and in the hook portion serves to provide at the bite of the bend a smooth arcuthis invention I. provide a: pair of jaws resiliently related and a support. on.

ate surface to nicely conduct the thread along this surface and provide for some traverse of the thread by reason of the movement of the weight and the changing of the position of the guides l6 and 9 so that wear is distributed along this arcuate surface.

A notch 2'! is provided in the support l1 so as to leave -a recess 28 as shown in Fig.4. and Fig. 2 for the insertion of a small instru'mentsuch as a screw driver for snapping off or prying off the guide l6 from its support when it is desired to replace this guide with a fresh one.

From the above it will be apparentthat the a support l1 may serve to hayemountedi upon it a hook shaped yarn guide byc reasoni of merely pressing the yarn guide into position,the re being such a relationship between the thickness of the support l1 and the distance between the

parts

20 and 22 of the yarn guide that a tight gripping relation is had .to hold the yarnguide firmly in position. A notch in the end of thesupport permitsof easy access for removal ofthe yarn'guide,

secure the yarn guide in position.

The reverse bending of the guide and arrangementis such that pull on the yarn' tends to pull the "guide toward its seated position on the support preventing it fromfcomingloose due to vibra-- tion in the running ofthe carrier. To insure even further security of'holding the supports I! may be provided with serrations 30 extending horizontally along the'concavity 21' and the rib 23 may be provided with similar serrations 3! similarly extending along the portion thereof which engagesthis, notch 21 to interfit therewith.

fromjits pos ition, no rivets being necessary to I claim:

1. In a braider carrier, a weight, a support thereon, a one piece yarn guide bent into S shape with one loop providing one resilient jaw of a clamp to engage said support and grip the same, the other loop acting as a yarn guide through which the yarn passes.

2,. In a braider carrier, a weight, asupport thereon, a one piece yarn guide bent into S shape with one loop providing one resilient jaw of a clamp to engage said support and grip the same, the other loop acting as a yarn guide through which the yarnpasses, the stock of said guide being longitudinally offset to provide a rib to stifien the same.
