I SHUTTLE; Application filed January 18, "1922. Serial No. "530,190. To all whom it may concern. Be it known that I, JEANBAPTISTE -DAU- enmity-a citizen of the United States, residing at Fall River, county of Bristol, Commonwealth of Massachusetts, have invented certain new and useful Improvements in Shuttles, of which the following is a specification. i This invention relates to-shutt'les, and particularly to an automatically threading shuttle for "use in Weft replenishing looms, and-consists in the novel-construction, comb-i'nation and relationof parts described and illustrated in the accompanying specification and drawings, and particularly pointed out 'in the appended claims. dore specifically, my present invention relates to the means for guiding the Weft from *the Weftcarrier to the eye of the i'kccording to my invention, '1 mount-in "the shuttle throat between the Weft carrier andey'e a guide in the form of a helix which is preferably Wound in a direction opposite to the'unspooling action of the "weft from the Weft carrier so that the rotary motion of the Weft asit is drawn from the Wet carrier causes the Weft to Work inwardly towards the center of the helix Where it 18 held against improper escape. The construction and 'o aera'tio'nof my invention, together With selected embodiments which i Well 'illustrate'the principles involved, are described and illustrated in the iaccoinipa-n yi'n'g specification and d r a W in g s, throughout which like reference characters are correspondingly employed, and in the drawings: I -Figs, 1 and 2 'air eplan and side views, respectively, "of the threading end of an automatically threading shuttle of standardtype equipped in accordance With my invention. Fig. 3 is a perspective view of the autoinaticthreader removed from the shuttle and particularly showing the Weft guide, and i Figs. 4 and 5 are detail views of the eye piece removed from the shuttle. I have indicated at 1 the threading end of an automatically threading shuttle of standard type, atQ the shuttle throat, and at 3 a filled Weft carrier.

The passage 11 is formed as aslot cut vertically in "the body of the -eye piece beyond the post 10, leaving spaced side wallet and ti The Wall 6 of the eye piece diarthest removed froin the wvelit carrier, *is laterally cleared away adjacent the postlO '1;o provide au'veft inlet ehrough vvhi ch theyveft W =tWisting past said post l Oi fir'om the weft carrier enters the slot ll.

The outer end of the helix 'is be'nt subst an'tially "vertically downward {as indicated =at 22 and hooked The deflection bf "the aiiiilib'f- The helix is preferably wound in a direction opposite to the unspooling action of the weft. As the weft unwinds, it works its way towards the center of the guide where it is held against improper escape. The cover plate 18 of the casting is preferably extended horizontally, as indicated at 23, to overhang the guide coil 21 and maintain overhead bearing thereupon. Beyond the forward end of the guide 21 the cover plate 18 of the threader is provided with a downwardly extending guide surface 24: which is disposed substantia ly in line with the outer side wall 17 of the threader and past which the weft twists and is directed into the slot 11 of the eye piece. When the threader and eye piece are as sembled within the shuttle, the guide surface 2st fits over the forward edge of the snubbing post of the eye piece and said post itself is disposed in the space separating said guide surface 24 from the adjacent vertical forward edge of the wall 17 of the threader. Beyond the guide surface 24 the top wall of the threader is turned downwardly as a horn offset relative to said guide surface and between which and the guide surface 24 the weft passes into the eye piece. At the delivery end of the eye piece the cover 18 of the threader is turned down as a tongue 26 which overlies the slot 11 of the eye piece and with the shoulders 15 and 16 thereof prevents upward movement of the weft. The under edge of the tongue 26 is preferably notched centrally as indicated at 27 to overlie the threading passage 11 of the eye piece. The threader itself is fixed in the shuttle by a screw which passes through the walls 17 and 19. In threading the shuttle, the weft is drawn along the rounded outer face of the guide 22 between the guide surfaces 24 and 25 of the threader and the post 10 of the eye piece into the passage 11 0f the eye piece. As the weft passes into the eye piece, it slides down the outer convolution of the guide 21 and works itself through the passage 29 towards the center of the helix. Vvhile I have shown and described my invention in its adaptation to an auton1atically threading shuttle, it will be understood that the principles involved are applicable to a hand threading shuttle, and that the invention is to be so construed. Various other 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. an automatically threading shuttle having a weft carrier, an eye, and a threader located between said weft carrier and eye, a guide carried by said threader and consist-ing of a plurality of spaced helical. turns laid in a direction opposite to the unspooling action of the weft whereby the weft will automatically work itself inwardly towards the center of the guideas it runs from the weft carrier. 2. In an automatically threaded shuttle having an eye piece, a threader comprising a spaced horizontal top wall, a depending substantially vertical wall and an extension of said vertical wall spaced therefrom and defining therewith and with the top wall a recess, and a guide mounted in said recess and consisting of a plurality of spaced helical turns, the outer turn being extended as an attaching portion engaged with said e2;- tension of the vertical wall of the threader. 3. In an automatically threaded shuttle having an eye piece, a threader comprising a spaced. horizontal top wall, a depending substantially vertical wall and an extension of said vertical wall spaced therefrom and defining therewith and with the top wall a recess, and a guide mounted in said recess and consisting of a plurality of spaced turns. 4i. In an automatically threading shuttle having an eye piece, a threader consisting of a substantially horizontal top wall, a depending side wall, a horizontal bottom wall at the lower edge of said side wall and a sub stantially vertical side wall rising from said bottom wall and defining with said opposite wall and said top and bottom walls an open ended recess, a guide mounted in said recess and consisting of a plurality of spaced turns, the outer turn extending as an attaching portion disposed against said upturned side wall and fastened thereto. 5. In an automatically threading shuttle having an eye piece, a threader consisting of a substantially horizontal top wall, a depending side wall, a horizontal bottom wall at the lower edge of said side wall and a substantially vertical side wall rising from said bottom wall and defining with said opposite side wall and said top and bottom walls an open ended recess, a guide mounted in said recess and consisting of a plurality of spaced turns; the outer turn extending as an attaching portion disposed against said upturned side wall and fastened thereto, and a pair of spaced thread deflecting surfaces extending from said top wall of the threader beyond said guide for deflecting the weft into said eye. 6. In an automatically threading shuttle, an eye piece having a snubbing post and a threading passage beyond said post, a threader consisting of a substantially horizontal top wall, a depending side wall, a horizontal bottom wall at the lower edge of said side wall and a substantially vertical side wall rising from said bottom wall and defining with said opposite side wall and said top and bottom walls, an open ended recess, a pair of spaced thread deflecting surfaces extending from said top wall of the threader adjacent said snubbing post, and a guide mounted in said recess of the t-hreader in rear of said deflecting surfaces. 7 In an automatically threading shuttle, an eye piece consisting of a member having a substantially flat surface over which the thread runs and having between the ends of said surface a substantially vertical snubbing post, said member beyond said snubbing post having a pair of spaced walls and the space between said walls providing athread passage. 8. In an automatically threading shuttle, an eye piece consisting of a member having a substantially flat surface over which the thread runs and having between the ends of said surface a substantially vertical snub JEAN BAPTISTE DAUDELIN. lVitnesses 'LILLIAN F.
