Application filed September 12, 1912. Serial No. 719,959:

and State of Massachusetts, have invented certain new and useful Improvements in Loom-Shuttles, ot whichtheA following is a speciication.

This invention relates to improvements in automatically ,threading loom shuttles such as are employed in wett-replenishing looms in which the weft-replenishment is accomplished by ejectiug the spent weft-carrierfrom the shuttle and substitut-ing a lled weft-carrier therefor. Such loom shuttles are provided with slotted eyes into which the wett thread automatically enters as a result of the flights of the shuttle through the shed.

In order to prevent the thread cutting into the wood of the shuttle it has been a common practice to guard the shuttle-eye by means qf metal guides against which the thread runs. Such metallic guides are not eilective in the case of worsted, woolen and other coarse yarns which rapidly cut into the metal' which results in the frequent cutting and breaking of the threads.

In old-style shuttles used on common looms and provided with eyes having unbroken peri heries, it was customary to efnploy porc ain eyes with such threads through which the thread was drawn commonly by sucking it through. Such eyes are not capable of use in wet-replenishing looms of the type underconsideration.

Various expedients i for curingthe difficulties incident to metallic. guides in automatically. threading shuttles when worsted and similar rough yarns are employed. For example, it has been .proposed to provide metallic guide rollers which rotate as the, yarn is drawn over them, thusincreasing the surface over which the yarn is drawn, as in the .United `States LettersPatent of Draper, No. 968,647, August 30, 1910, but this involves a necessarily expensive construction, careful work being necessary to enable thel necessarily and such rotating guide rollers simply postpone the cutting by the yarns and do not avoid it. It has also been proposed to equip the shuttle-eye with a slotted porcelainV block, as in theUnited States Letters Patent of Stimpson, No. 1,017,065, February 13, 1912. In the pracing and eyeportion being broken away havebeen suggested one of the vitreous gu1de posts.

- vice which tical manufacture and use of such porcelain l blocks it-has been found almost impossible to make a shape which will not vbe broken withthe jar of the shuttle in the loom.

In accordance with the present invention, guide posts .of vitreous material, preferably porcelain, are so constructed and mounted in the shuttle as to .avoidy the objections heretofore encountered with porcelain blocks,l

and the present improved porcelain guide posts wear indefinitely whenworsted and similar yarns are employed. v

The accompanying drawings illustrate the present improved vitreous guide posts applied to an automatically threading shuttle, having the automatic threading devices which are disclosed in the United States Letters Patent of Stimpson, No. 933,497, September 7 1909.

In the drawings- Figure 1, is a plan view of the threading and eye-end of a shuttle equipped with the present improved vitre-A ous guide posts, a port-ion of the sheetmetal threading device being broken away to facilitate the illustration. vFig. 2, is a similar view of theshuttlebut showing the threadof the shuttle in horizontal section. Fig. 3, is a side view of the shuttle looking toward the eye, and parts and Ishown in vertical section. Fig. 4, is the plane indicated by the line 4-4, in Fig. 1. Figs. 5, and 6, are perspective views of the vitreous guide posts. Fig. 7, is a side view of the sheet-metal threading device showing the adaptation thereof to receive FigQS, isa vertical transverse section through the inner guide post and the parts of the shuttle immediately associated therewith. Fig. 9', is a detail upsidedown view of the wooden holder for the top of the inner guide post. As shown in the drawings, A, is' the shuttle having a slotted side-eye B, in one side, and C, is the sheet-metal threading deis substantially `like that shown in the. aforesaid Stimpson Patent, No. 933,497, except that it is recessed vertlcally, as shown'at a, in Figs. 1 and 7, at its side wall next to the eye B, for the purpose o accommodating the inn'er guide post and the ened for the same purpose, as shown, ex-

tending toward the eye B, only a short disa transverse section in cylinders,

tance beyond the usual fastening bolt D, `instead of extending substantiallyI tothe rear edge of the eye as in said Stimpson patent.

The'threading device has 'the usual longi- `The inner guide post E, is located so that the yarn extend-ing from the weft-carrier within the kshuttle lengthwise of the longitudinal thread passage o?, and thence laterally out through the eye B, will come in contact with its surface, as shown in Fig. 2. Otherwise stated, this E, intercepts the path of the yarn as it passes from the weft-carrier within the shuttle to the eye. The other two outer porcelain posts "F Gr, guard the front and back of the eye B. When the shuttle is traveling forward, the -yarn runs against the guide post G; and when the shuttle is traveling in the opposite direction the yarn runs against the guide post F.

y The porcelain posts are preferably hollow as illustrated in the drawings, since when so constructed they have been found less liable to break in useand they Iare more easily removed from the shuttle for repairs in case occasion should arise for replacing them with other porcelain posts. The two outer guide posts F, and G, are alike and hence both are illustrated by Fig. 5, and they are bot-h inserted and held within the shuttle in dilerence being that they are located on opposite sides of the shuttle eye. The inner guide post E, is longer than the two outer guide posts, as shown in Figs. 4c, and 6, and

' appropriate vertical holes are spective guide posts snugly lit.

it is inserted in the shuttle and held at its bottom therein the same way as the two outer guide posts, but its upper end is secured by a special holder. The three porcelain guide posts are held snugly and securely in place so that there is no rotation or other movement of the shut-tle.

For the reception of the threev guide posts bored from the bottom of the shuttle in which the re- Each guide post is held in place by a wooden block H, which is glued into the bottom of the appropriate bore after its guide post has been inserted. The upper end of each outer guide post H, is retained in place by means of a socket I, formed in the body of the shuttle adjacent to where the threading slote, communicates with the eye and where thewood of the shuttle body overhangs the eye. As shown in Fig. 2, the bores for the reception of outer posts F, and G, are so located thereof during the use 'o f the periphery of these inner guide post' the same way, the only' with respect to the sides of the shuttle eye B, that'a suiiicient portion of the periphery of the posts F, and G, is exposed for the yarn to run over, while the major portion guide posts 1s within the bores so that they are protected by the wood of the shuttle body.

A special construction is employed for holdingthe upper end of the long inner porcelain post E. The holder K, for the upperend of the porcelain post E, is a sepavrate piece of wood, glued into place to the i body of the shuttle, being glued at itsbottom and at its-vertical walls where it is adjacent to the wooden body of theshuttle. This `wooden holder has top vand bottom flanges f, g, which are appropriately bored to receive the inner porcelain post E. The socket L, in the upper flange f, which receives the upper end of the porcelain post does not extend clear' through said fiange, and the upper face of said flange is beveled as shown in Figs. 4, 8,- and 9, to aid in directing the yarn into the thread Apassage d. The automatically threading shuttle thus equipped with the hollow porcelain guide posts, firmly held in place in the shuttle, meets all the practical requirements where worsted and vsimilar rough yarns are used.
