' SHUTTI-LEFEYE.

new and useful Improvements in Shuttle Eyes, ofwhich the following is a specific'atlOIL.

This invention relates to certain new and useful nrnprovements 1n shuttle eyes, and

r the primary object thereof is ,to providean eye which has means incorporated therein for stopping and cutting any bunch of thread passing to theeye l In the weaving of tirefabric it is'essential that there should be no knots that is to say in the sense of a bunch woven into the fabric, and accordingly the presentinvention aims to provide an eye which will stop and cut the bunch, or break the yarn.

A further object of the invention is to provide means for attaining the function above pointed out, which can be easily and simply made or provided, and more specifically to provide for such formation by simple and opposite drilling operations.

The invention still further aims to simplify the construction of eye of this character, and to generally improve same.

Further and other ob ects w1ll be later set forth and manlfested 1n the course of the following description.

In the drawings:

Figure 1, is a top plan view of the invention embodied in a shuttle;

Fig. 2, is a side elevation;

Fig. 3, is a top plan view of the eye par tially formed and shown removed from the shuttle, and

4.. is a section on line 4-4: of Fig. '3. In proceeding in accordance with the present invention an eye is employed whichhas an axial thread passage 1, a radial slot 2 leading into the passage and a diagonal out or slot 3. while the periphery of the eye is reduced in diameter at 4c, the slot 3. terminating in the guide hole 5. The opposite end of the eye is threaded at 6, to permit same to be secured in position and removed at will.

The interior of the passage 1, is provided with a pair of somewhat sharp cutting points 7 which extend inwardly toward each other in confronting relation and are Y pa e to al ow the thread to p ss/th re Specification of ietters' Patent. lflatented Deg, 13, 19121, Application" filed rebruar lafliezi. .Serial No. 444323 between as shown in Fig. 4:, of the drawings. These points or extensions. are formed by first boring on drilling from each end of the body with abit having a point to cut or form approximately V-shaped'bottoms indicated at 7*, in Fig. 3, following which, the-thread '6, is formed or cut; the slot3 and the 'guidehole lfnext formed, and finally the radial slot 2, .thelatter passing through the web 8, formed'by the bored parts 7*, to thus provide the space 9, separating-the cuttingpoints or extensions as depicted 1n' F1g;4L..

" In operation, 'thethreadpasses froni the bobbin and'through the throat into the slot 3 and guide eye 5, and thence enters the passage 1, and out from the delivery'side of the eye. If, in its passage through the space 9, -the' thread should have a bunch or the like, same will be caught by the points or projections 9, and cut, thus -pre-- venting the weaving of knots or bunches into the fabric. In order to prevent accidental unthreading, a ledge 10, is formed in the shuttle body and extends-above the periph-. eral cut-out 4:, so as to thereby guide the yarn or thread. 7 I I From the above it will be apparent that the threadis notv only out if possessed of bunches or knots, but in addition means are,

provided to prevent accidental unthreading.

and at the same time a-unitary structureis provided which can be simply and easily made and at slight cost. I

Having thus described my inventiomwhat I claim as new and desire to secure byLetters Patent is: l V

r 1. In a shuttle, an eye having an axial passage and formed with a radial slot lead; ing thereinto and a diagonal slot, terminating in a guide hole, and having a peripheral cut-out extending from the radial slot upwardly, a guard borneby the'shuttle body and extending above the lower end of the peripheral cut-out. and a pair of cutting projections extending into the axial-passage and having theirv free ends confronting and spaced and formed to permit the I passage of the yarn and to cut same upon any bunches or knots borne by the yarn encoun'teringthe projections.

2. In a shuttle, an eye having an axial thread passage and having a web extending across its interior, said eye having a transverseslot and a radial slot, the latter extending diametrically through the Web and communicating with the transverse slot.

31 In a shuttle, an eye having a thread passage and a pair of diametrically opposed approximately segmental shaped thread cutters in the passage extending inwardly from the circumferential wall of the passage and having their chords free and spaced apart.

4. In a shuttle, an eye having a thread thread passage, a radial slot extending axially ofthe eye and leading from the passage through the periphery of the eye, a

peripheral cut-out extending from the slot up along side of the eye, and a transverse slot formed in the eye and terminatingin a guide hole, one end of the transverse slot extending into the radial slot.

7. In a shuttle, an eye having a bore extending inwardly from each end to leave a web therebetween, the latter having opposed concave faces, the bores forming a thread passage, the eye having a slot extending into the passage and through the Web.

8. In a shuttle, an eye having an axial thread passage and having a web extending across its interior and having a cut to form a pair of opposed cutting members therein each having a free end, and having their free ends spaced from one another.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
