UNITED STATES JEAN B. DAUDELIN, OF FALL RIVER, MASSACHUSETTS.

SHUTTLE.

Application filed April 13, 1923. Serial No. 631,918.

To all whom it may concern:

Be it known that l, J EAN B. DAUDELIN, a citizen of the United States, residing at Fall River, county of ,Bristol, Commonwealth of Massachusetts, have invented cert ain new and useful Improvements in Shuttles, of which the followingis a specilication'.

This invention relates to automatically threading shuttles for use in weft replenishing looms, and involves certain improvements over the shuttle described and claimed in my prior application, Serial No. 580,190, filed January 18, 1922, to which reference is made as illustrating the type of shuttle involved herein.

My present invention is particularly di rected to the construction of the threader it self, to the end that the shuttle may be quickly and conveniently threaded and that when threaded the weft will be prevented from improper escape from the threading eye during the run of the shuttle, and consists in the novel construction, combination, and relation of parts described and illustrated in the accompanying specification and drawings and particularly pointed out in the appended claims. Throughout the specification and drawings like reference characters are correspondingly applied, and in the drawings Fig. 1 is a partialplan view at the threading end of an automatic loom shuttle of standard. type equipped with a threader in accordance with my invention.

Fig. 2 is a side elevation thereof.

Figs. 3 and 4: are side elevations of the threader removed and viewed from the delivery and intake ends, respectively, of the threading eye, and

Figs. 5 and 6 are end elevations as viewed from the right and left, respectively, of Fig. 3.

I have indicated at 1 a portion of a loom shuttle of standard type, at 2 the shuttlethroat, at 3the threading eye and at 1 the weft carrier. My threader is indicated generally at T and is mounted in approximately the longitudinal axis of the shuttle throat. As here shown the threader is a metallic casting comprising a top wall 5, a depending vertical sidewall 6, a bottom wall 7 and an upturned vertical extension 8 defining with said walls 5, 6 and 7 an openended recess within which is mounted a thread guide 9. The bottom wall 7 has a depending stud 10 adapted to fit within a hole formed in the bottom of the shuttle throat and the vertical extension8 thereof is shouldered at one, end as indicated at 12 to fitwithin a vertical groove in the shuttle body and key the threader in the shuttle throat.

- The guide 9 is preferably a helical coil seated in the open-ended recess of the threader and at its rear end'abutting a narrow shoulder 10 formed on the under face of the top wall 5 of the threader. This shoulder prevents the weft W from lifting out of the coil during the run of the shuttle. Beyond the shoulder 10 the top wall 5 of the threader extends as a downturned guide tongue 11 effective in threading to direct the weft from the weft carrier downwardly into the guide coil.

One end of the coil is bent substantially vertically downwardly as indicated at 9, Figs. 4 and 5, to overlie the upturned wall 8 of the threader, the rear edge of said eX- tension 9 abutting the shoulder 12 of said wall. The extensions 8 and 9 and wall 6 are pierced by a hole 13 for the reception of the anchoring screw 1 1, Fig. 2, which passes transversely of the shuttle throat from side to side thereof and fixes the threader within said throat.

Beyond the forward end of the guide coil, the top wall of the threader is provided with a depending vertical snubbing post 15 disposed substantially in line with the axis of the guide coil. Forwardlyof said guide post 15 and offset laterally with respect thereto, is a downwardly and rearwardly tapering guide pin 16 formed integrally with the top wall of the threader and terminating short of the lower end of the snubbing post 15. The wall 6 of the threader is notched, as indicated at 17, Fig. 3, to permit the weft to pass laterally from the guide pin 16 "into the intake end of the threading eye. Extending laterally over the threading eye from thetop wall of the threader, is a downwardly and rearwardly disposed tongue 18 from which depends a vertical rib 19. The rib 19 is parallel to the longitudinal axis of the threading eye and slightly in advance thereof. There is a clearance between the forward edge of the tongue 18 and the wood of the shuttle at this side of the shuttle eye, such clearance conlet slot 31 of the eye.

, thenotch 17 into the eye.

stituting an inlet port 18 by means of which the weft, in threading, may enter the eye 3 from above, the rib 19 terminating short of the overlying tip of the tongue 18, as indicated at 19, Figs. 5 and 6, to permit the weft to clear said rib in entering the eye. The extreme forward end of the threader at the side opposite the tongue 18 is formed with a down-turned guide tongue 20.

The threading eye 3 is provided with a vertical inlet slot 21 opening into said eye from above and'connecting with the port 18, and at its delivery end, a pair of guide pins is set through the wood of the shuttle on either side of said eye. Thesepins define the delivery end of the eye. The intake end of the eye is defined by the metal of the threader on either side of the notch 17, the snubbing post 15 being disposed substantially in the longitudinal axis of the eye in rear of said notch.

In threading the shuttle, the weft from the weft carrier 4 is drawn into the space between the outermost turn of the helical guide coil and the anchoring portion 9 thereof, the guide coil being preferably wound in a direction opposite to the unspooling action of the weft so that the weft will automatically work its way towards the center of the coil. From the coil the weft passes over the snubbing post 15 and down the guide-pin 16 into the'port 18 along the forward side of the rib 19 and into the in- The shuttle is now threaded and the weft runs from the coil directly past the snubbing post 15 and through Any tendency of the weft to escape by direct, upward lifting movement is met by the rib- 19, which thus prevents the weft from drawing backwardly along the tongue 18 into the port 18. The

weft is therefore compelled to pass outwardly between the guide pins 22.

Various modifications in the form and construction of my device may obviously be resorted to without departing from the spirit of my invention if within the limits of the appended claims.

What I therefore claim and desire to secure by Letters Patent is 1. In a shuttle having a threading eye, a threader mounted longitudinally of the shuttle throat, a tongue overlying the threading eye and defining with the adja cent portion of the shuttle body a thread inlet port opening into said eye from above and a vertical rib depending from said tongue and extending above and parallel to the. longitudinal axis of said eye and constituting a barrier effective to prevent escape of the weft from said eye by an upward lifting movement.

2.

3. In a shuttle having a threading eye, a threader mounted longitudinally of the shuttle throatand having a notch defining the intake end of the threading eye, a tongue overlying said notch and defining with the adjacent portion of the shuttle bod a thread inlet port opening into said eye rom above, and a rib depending from said tongue and extending above and parallel to the threading eye in slightly offset relation to the longitudinal axis thereof and constituting a barrier effective to prevent escape of the weft from said eye by an upward lifting movement.
