UNITED STATES PATENT OFFICE.

SHUTTLE.

Application filed April 13, 1923. Serial No. 631,917.

Q T all whom it may concern:

Be it known that I, JEAN B. DAUDELIN, a citizen of the United States, residing at Fall River, county of Bristol,' Common wealth of Massachusetts, have invented cer tain new and useful Improvements in Shuttles, of which the following is a specification.

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 Number 530,190, filed January 18, 1922, to which reference is made as illustrating the type of shuttle involved herein.

y directed to the means for guiding the weft through the shuttle eye, 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. v Throughout the specification and drawings like reference characters are correspondingly applied, and in the drawings Fig. 1 is a partial plan view at the thread- .ing end of an automatic loom shuttle of standard type equipped in accordance with my invention.

Fig. 2 is a side elevation thereof.

Fig. 3 is an end view of the automatic threader removed from the shuttle, and

Figs. 4 and 5 are diagrams illustrating the threading action, Fig. 4 showing the position of the weft in threading the shuttle, and Fig. 5 the position thereof after the shuttle has been threaded.

I have indicated generally at T-an automatic threader in accordance with my invention. The threader is mounted in approximately the longitudinal axis of the shuttle throat and as here shown is a metal casting comprising a top wall 1, a depending vertical side wall 2, a horizontal bottom wall 3 and an up-turned extension 4 definingwith said

walls

2 and 3 an open ended recess within which is mounted a thread guide 5.- V f i The guide 5-is preferably a helical coil, the outer end of which is bent substantially vertically downward as indicated at 6 to overlie the up-turned wall 4 of the threader. The extension 6, wall 4 and the opposite side wall 2 of the threader are pierced by a hole for the reception of an anchoring screw present invention is particularly -8 which passes transversely through the throat of the shuttle from side to side thereof, I v The upper face of the outermost turn of th guide coil is notched as indicated at 9 and said notch acts to prevent the weft W from slippingoff'the guide as it is drawn from the weft carrier 10 of the shuttle. The weft passes into the space between the outer turn of the guide and the anchoring portion 6 thereof and-inasmuch as the helical coil is preferably wound opposite to the unspooling action of the weft, the weft as it unwinds works its way towards the center of said coil where it is held against improper escape, being centered by the notch 9.

At its forward end, the top wall of the threader is provided with a downwardly ex tending guide surface 11 which is disposed substantially in line with the outer side wall of the threader. Adjacent and spaced 1 from said guide surface 11 is a downwardly turned tongue 12 between which and said guide surface the weft passes from the helical coil to the threading eye of the shuttle when the shuttle is being threaded. Ex-

tending as a continuation of the guide surface .11 is a vertically disposed snubbing post 13. Rising vertically from the bottom of the shuttle eye is a snubbing post 14.

The

posts

13 and 14 are disposed substan- I tially in line with each other at the inner end of the threading eye and in effect define the inner'end of said eye. In. addition toits guiding function the post 14 also assists to center the threader in the shuttle, the upper wall of the threader being pierced by a hole to receive said post. Beyond the pin 13, the top wall of the threader slopes downwardly and rearwardly as a guiding tongue 19. This tongue is tapped and threaded to receive an anchoring screw 20-.

The outer end of the threading eye is de fined by a pair of spaced vertically disposed

guide pins

15 and 16 which are clinched within the wood of the shuttle. At its upper end the pin 15 is bent over upon itself as indicated at 17, and extended across the delivery end of the threading eye to provide a guide for the weft effective to direct the weft in the eye during the threading of the shuttle and constituting an overlying guide to prevent improper escape of the weft from the eye by a direct upward lifting movement after the shuttle has been threaded. The terminus of the angularly' bent portion 17 of said guide pin 15 is disposed in a notch 18 out in the wood of the shuttle at the left hand side of the threading eye as viewed in Fig. 2, so that in threading the weft passes from the. helical coil 5 around the snubbing post 13, under the clown-turned tongue 19 at the forward end of the threader and is deflected along said guide portion 17 into the notch 18 from which it passes under the guide portion 17 into the threading eye. (See Fig. 4-.) The shuttle is now threaded and the weft drawsdirectly past the snubbing post 14 and out between the

pins

15 and 16, as shown in Fig. 5.

Various modifications in the form and construction of my device may obviously be resorted to, all 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 mount-ed longitudinally of the shuttle throat and having a guide disposed transversely to the axis of said eye, a pair of spaced snubbing posts disposed in sub stantially longitudinal alignment with each other and defining the intake end of the threading eye, a pair of spaced guide pins disposed in substantially longitudinal alignment with each other and defining the delivery end of said eye, one of said guide pins being extended across the threading eye and constituting a guide for directing the weft into said eye as it draws past the forward snubbing post in threading and a barrier for preventing escape of the weft from said eye as it draws past the rear snubbing post after the shuttle has been threaded.

2. In a shuttle having a threading eye, a threader mounted longitudinally of the shuttle throat and having a guide disposed transversely to the axis of said eye, and a depending vertically disposed snubbing post, a snubbing post spaced from and disposed in substantially longitudinal alignment with said first named post and defining the intake end of the threading eye, a pair of spaced guide pins disposed in substantially longitudinal alignment with each other and defining the delivery end of said eye, said pair of guide pins and said pair of snubbing posts being arranged in substantially horizontal alignment relative to each other, and the upper end of the guide pin aligned with the forward snubbing post being extended across the threading eye and constituting a guide for directing the weft into said eye as it draws pastthe forward snubbing post in threading and a barrier for preventing escape of the weft from said eye as it draws past the rear snubbing post after the shuttle has been threaded.

3. In a shuttle having a threading eye, a

threader mounted in the shuttle throat and having a helical guide coil disposed transversely to the axis of said eye, said coil having a notch in its outermost turn effective to prevent the weft from slipping off the coil, a pair of spaced snubbing posts defining the intake end of said eye, and a pair of spaced aligned guide pins defining the delivery end of said eye.

4. In a shuttle having a threading eye, a threader mounted in the shuttle throat and having a tongue overlying the threading eye, a guide pin at the delivery end of said eye and having its upper end extended towards the opposite side of the threading eye and spaced therefrom to permit passage of the weft running over said bent portion into the eye in threading the shuttle, said bent portion when the shuttle is threaded constituting a barrier overlying the threading eye and effective to prevent escape of the weft by direct upward lifting movement.

5. In a shuttle having a threading eye, a threader mounted in the shuttle throat and having a downwardly turned tongue overlying the threading eye, a guide pin set through the wood of the shuttle at the delivery end of said eye and having its upper end bent downwardly and extended towards the opposite side of the threading eye and spaced therefrom to permit passage of the weft running over said bent portion into the eye in threading the shuttle, said bent portion when the shuttle is threaded constituting a barrier overlyingthe threading eye and effective to prevent escape of the weft by direct upward lifting movement, and a pair of spaced vertically disposed posts at the inner end of the threading eye, one of said posts constituting a snubber past which the weft is drawn into said eye during the threading action of the shuttle and the other post constituting a snubber past which the weft runs directly into said eye after the shuttle has been threaded.

6. In a shuttle having a threading eye, a threader mounted in the shuttle throat and having a tongue overlying the threading eye and a guide in rear of said tongue and disposed transversely to the axis of said eye, a pair of guide pins defining the delivery end of said eye, one of said pins bent over at its upper end and extended towards the opposite pin but spaced therefrom to permit passage of the weft running over said bent portion into the eye in the threading of the shuttle, said bent portion when the shuttle is threaded. constituting a barrier overlying the threading eye and effective to prevent escape of the weft by direct upward-lifting movement. e

, 7. In a shuttle having athreading eye, a

threader mounted in the shuttle throatiand posed transversely t0 the axis of said eye, a pair of guide pins defining the delivery end of said eye, one of said pins bent over at its upper end and extended towards the opposite pin but spaced therefrom to permit passage of the weft running over said bent portion into the eye in the threading of the shuttle, said bent portion when the shuttle is threaded constituting a barrier overlying the threading eye and effective to pre-' vent escape of the weft by direct upward lifting movement, and a pair of spaced vertically disposed posts defining the inner end of the threading eye and aligned with said pair of guide pins, one of said posts c0n-. stituting a snubber past which the weft is drawn into said eye during the threading action of the shuttle and the other post constituting a snubber past which the weft runs directl into said eye after the shuttle has been t readed.

In testimony whereof I afiix my signature in presence of two witnesses.
