AUroMATIcALnY-THREADING LOOM-SHUTTLE.

Specification of :Letters Patent.

Patented .rune e2, 1909.

Application iednprir 29, tiene) serial No. 429,803;

To? allwhom it may concern: j j Be it knownthat I, JONAS NonrI-rnor, a citizen of the United States, and resident of I-Iopedale, county of Vorcester, State of Massachusetts, have invented certainI new and useful Improvements in Automatically- ThreadingLoom-Shuttles, of which thefol` lowing is a full, clear, and exact specification;

In automatic iilling changing looms lthe shuttle is the vital feature, for the meohan ical change of bobbins in the active shuttle requires the shuttle to contain a device which will not only hold the bobbin in proper i position while the yarn 1is being woven off,

but which will release the oldbobbin andre` ceive the new one almost instantaneously' at the time of the change. In addition rovision` must be made for engaging the f ing Y thread separately and carrying it into the delivery`-eye` without breakingg'so that the Y threadxwill deliver freely and properly as the `shuttle is picked. Furthermore the thread must be retained in its guiding and controlling means when the shuttle is stopped suddenlyat the end of each pick and the thread-controlling means should be properly guarded so that loops ofthread which are thrown forward at such times may not catch on any of the parts V*and break on the return pick of the shuttle. Devices to insure the proper performance 'of these functions,iand others to be referred to later, must be embodied in an object which 1s thrown across a loom from one hundred `and i'ifty to twoliundred times per minute,

sands of warp threads, which are not fully separated Vwhen the shuttle enters the space between them, and which are partially closed `when the Shuttle `completes its stroke, `so

. that the shuttle must be made with conical ends free from all projections orfroughness which would'icatch or break-a single warp thread. These are the main essentials of an automatic loom-shuttle, but there are to economize power and reduce wear and breakage incident to its rapid motion and suddenrstoppages. `A permanent and erliclentctenslonf deviceA for theiilhng 1s` a great desideratum. Tension 1s! necessary toprevellt bad selvages andkinks in the cloth,

and it is generally obtainedby the useofa piece olf-felt or flannel, which wears out and is'irregularin itsfoperation.A An adjustable metallidtension device is `also a desirable feature. j j j In-mv present inventionI have produced a shuttle whichfmeets' every requirement of weaving aswell as its numerous predecessors,

but which is greatly improved in various j important particulars. i

i improved shuttle is lighter than automatic shuttles now in use, because of the simplification of the threading means; it is very strong and durable, and it is provided with an adjustable, metallic tension device and it is thoroughly efficient in its action on the thread. The construction and arrangement ofthe threading means'is such that proper deliverable control of the illing thread is effected bythe motion of the lay before or coincident with the pick, rather than by the motion of the shuttle through the warp after the pick, this operation forming the subject-matter of `an application Se.

` No. 415,180 iiled by me and another on the 10th day of February, 1908.

My improved shuttle is so constructed j' that if a loop is formed and thrown forward `by the sudden `stop at the end of each pick,

it will not unthread the shuttle, loops so formed and thrown forward being directed to one side so that it is practically imposi sible for them to catch and hold on any part of the threading means.

matic loom shuttle which will make the I believe that I have produced an auto- 'time I have improved the shuttle in impor-` tant `particulars not directlyconnected `with the changes of filling, as will be described hereafter in the Specification and pointed out in the claims.

Figure 1 is a top plan view of the .thread-` delivering end of a loom shuttle embodying in its structure an approved form of my invention; Fig. 2 is a front elevation thereof; Fig. 3 is a cross-section on the line 3&3, Fig.

i 1, looking forward; Fig. i is a cross-section of the shuttle body on the line 4--4, Fig. 1,

with the threading means in elevation; Fig.

Fig. 7 is a perspective view of the delivery end of the shuttle showing the threading' means in position g Fig. 8 is a top plan view of the delivery end of the shuttle body, but with the threading means omitted; Fig. 9 is a cross-section about on the line 9 9, Fig.

1 1, looking` toward the left, to show more clearly the construction whereby the filling thread can freely pass from behind the beak of the threading means down under it and frontward, but cannot escape thereafter under the beak in a backward direction.

The means for holding the bobbin in position in the usual elongated 'opening made for the purpose in the shuttle body 1 is not a part of my present invention, and may be ofany suitable construction, and I have shown herein only the end of the shuttle from which the filling thread is delivered, the threading means being located at the-adjacent end of the bobbin receiving opening 2. The'shuttle-body is cut away or inclined at its rear side to form one wall 3 of a substantially V- shaped opening or recess, the opposite wall thereof being formed by the diagonal side 4 4of the threading block, the wall 3 extending forward from the bobbin opening 2 to a point about opposite the beak 5, to be more particularly referred to later. Said wall has an overhang or jog 6 near its inner end, and opposite the beak it is cut away or recessed to form a pocket 7 into which the beak depends, the outer side of the pocket presenting a lip or guard 8 the front upright edge of p which stands forward slightly beyond the front edge of the beak.

Referring to Fig. 1 it will appear that the open base of the V-shaped opening formed by the walls?) and 4 extends from the bobbin opening well outward nearly to the beak, constituting the entrance to the passage through which the thread travels on its way from the tip of the bobbin to the deliveryeye of the shuttle, permitting the thread to freely enter the passage and drop into the best position to pass under the beak, when a change of filling occurs, the incline of the wall 3 causing the thread to slide downward toward the front of the shuttle and into the thread passage. Forward of the pocket 7 the shuttle wood is cut away to form a diagt onal groove 9 which terminates at the front downward at 16 back of the entrance slot 12,

and cut away at the front to leave the diagonal shoulder 17 which extends beyond the incline 16 to the slot 12. A vertical hole 19 is bored in the bed 15, and a second hole 20 is formed partly in the back wall of the bed and partly in the bottom of the recess 14, for ya purpose to be explained. .The lower part of the recess 14 forms the bottom of the longitudinal thread passage through which the thread travels to the delivery-eye, guided and controlled by the threading means which I Will now describe.

A metal casting of brass or other suitable metal is shaped to present a flat, elongated head 21 having a practically straight rear edge from which depends a web 22 the face of which forms the diagonal wall 4 hereinbefore referred to, the head being extended beyond thewall to cross or overhang the thread passage, terminating in the elongated, outwardly and frontwardly inclined beak 5 it being understood that the front of the shuttle is that side thereof containing the delivery eye. 'Ihe back wall 23 of the beak isY quite sharply beveled toward the'front of the shuttle, and approaches the adjacent portion of the shuttle wood opposite the pocket, the beak itself dipping into the pocket, see Fig. 9, and also Fig. 7, so that the guard lip projects in front of'it. A cylindrical tang 24 depending from the opposite end` of the head enters the hole 19 when the under side of the head seats on the bed 15, and the adj acent end of the web 22 is made rounding and extended at 25, to fit in the recess and hole 20, firmly positioning the threading block. The outer end of the web is inclined downward and inward from the under side of the beak to the tang 25, and a combined horn, thread-guide and down-hold is applied thereto. This -member I make of a piece of steel, see Figs. 4, 5 and 6,. and indicated at 26, curved in the direction of its length and having reduced ends which are snapped into sockets 27, 28, formed in the under part of the head and the tang 25, respectively, the resiliency of the steel, and the adjacent part of the shuttle body tightly holding the part 26 in place and obviating brazing, soldering or other mode of attachment. Viewing Fig. 4 the rear edge 29 extends diagonally from under the beak toward the rear wall of the thread passage, and at its lower end is notched at 30, the edge 29 and the convex face of thevpiece 26 constituting the horn to guide and direct the thread down into the `entrance slot 12 and thence to the deliveryeye of the shuttle while the notch 3() overhangs `the thread as it travels through the thread passage and holds -the thread down in proper position.` The relative positions of the 'downhold and the eye are very plainly y on the incline 16 shown in Fig. 8.

shown in Figs. 4t and A5.

The front -edgeof thehead 21 is of an elongated ovalshape, Figs. 1 and 7 and the head isconvexed and downturned at 81 to 'ht the front wall of the shuttle above the shoulder 117 and `to closely abut upon said shoulder,

.said slot and thence to the eye.

The flange 17 and the portion 18 of the shuttle-wood act as a species of guard to prevent the thread from drawing under the apex 33 of the downturned part 81 of the head, for as the thread must draw across those parts of the wood when pulled rearwardly directly yfrom the slot 12, as might happen, it cannot pass under the apex and be caught between it and the underlying Wood of the shuttle.-

Looking at Fig. 2 it will be seen that the flattened headhas a slight upward incline in a `diagonal direction to the beak, so that adjacent the latter the head is somewhat higher than the part of the shuttle-body behind it, see Figs. 3 and 4.

On the web 22 an overhanging hook 35 is formed, turned toward the jog or projection 6, see Fig. 1, but at a higher level than the downhold 30, though both the hook and downhold overhang the thread passage, asin Figs. 1, 3 and 4.

When a fresh bobbin is inserted in the shuttle the descent of the bobbin carries the filling thread leading therefrom down over the inclined wall 3 of the tl-shaped recess 3, et so that it will drop into the inner end of the thread passage, sliding over the oppositely inclined faces of the jog 6 and hook 35 and under the latter, soi that the thread cannot be thrown out at that point before the shuttle is completely threaded, or at any time thereafter. That is, after the thread passes under the hook it cannot be disengaged therefrom hy an upward and forward throw, for the jog 6 sheds the thread toward the front of the shuttle and thereby acts as a guard for the hook. As the thread passes down between the hook and its guard it is brought down behind the inclined face 23 at the back of the beak, which is at the highest part of the head 2.1, so that when the thread is tightened it slides downsuch face and behind the `tipof the beak the velevation of the head insuring tle is picked from the shuttle-box.

the positioning of the thread behind the beak Y as the bobbinV is transferred. ln the loom the lay at this point in the threading operation moves backand the thread held at a point exterior to the shuttle, is depressed and passes under the beak and across the guard 8, and is then drawn finto the groove 9 in front of the beak, all before or at the time the shut- Having passed under the beak and up in front of it `the thread is in deliverable condition and the shuttle is effectively threaded, for the thread draws outward along the groove 9 as the shuttle is moved across the lay and is trapped between the beak and the horn, and is prevented from escaping backward nnder the beak by the guard 8. The thread has a direct and free passage from the bobbin through the controlling means on the first pick after filling change, the thread traveling in a path closely approaching the longitudinal axis of the bobbin, and a so-called hopper-misthread is eliminated. As the shuttle continues itsmovement across the lay it is impossible for any mal-positioning of the thread, as the changing angle between the shuttle path and the filling leading from the shuttle to the filling-end holder has no effect upon the thread or its freedom of delivery. So far the thread has not been finally positioned in the thread passagenor led to the deliveryeye, as will be manifest, but on the return pick the thread is drawn up over the part 10 of the front wall of the groove 9 and thence down between the inclined face 11 and the opposed part 3a of the head of the threading block into the entrance slot 12 and the eye, at the same time slidingdown along the horn and into the downhold notch 30, and across the convex face of the steel plate 26. The shuttle is now completely threaded and the filling-thread is thereafter delivered through the eye 13, the downhold 30 retaining it in proper position and also keeping it in engagement with the `tension device, not yet described, the steel horn and downhold preventing cutting and wearing by the constant friction of the thread.

An ample space for the whirling or whipping motion of the thread as itleaves the tip end of the bobbin is provided by the V-shaped entrance to the thread passage, so that there is practically no chance for the thread to catch or hold, and any outward throw of the thread is caught by the hook 35 and held from passing toward and under the beak. The diagonal wall e of the threading device tends to direct any loops which may be formed toward the back of the shuttle and away from the beak, preventing catching of the loop or unthreading. The inclined or beveled rear wall tends to turn the unwinding thread toward the opposite side` ofthe thread passage, away from the entrance thereto, obviating any accidental release by the whirling motion of thethread and also facilitating the initial steps of the threading operation, as have been pointed out.

I have herein shown the tension device as a transversely arranged pin threaded at 36 to screw into a hole 37 in the back wall of the shuttle and having an eccentrically mounted, cylindrical bearing or engaging portion 38 for the thread as it passes from the obbin to the downhold 30, the thread engaging portion being located above the downhold, as clearly shown in Ifig. 4, and crossing the space between the converging walls 3, 4 below and somewhat nearer the bobbin opening than the hook 35. The front end of the tension device is circularly enlarged at 39 and concentric with the threaded part 36, to enter snugly a circular seat 40 in the web of the threading block, the support of the tension device being provided by the engagement of the part 36 with the threaded hole 37, but the engagement of the enlargement 39 with the threading block serves to positively and securely retain the latter in position in the shuttle. The end of the part 36 is slotted or otherwise shaped to be engaged by a suitable tool whereby it is screwed into operative osition, and then turned angularly more or ess to increase or decrease the tension. The higher the eccentric bearing portion 38 relative to the downhold 30 the greater the tension, as the thread must make a sharper turn or deflection, while the tension is reduced by turning down the portion 33 to decrease the deflection of the thread, the adjustment being instantly effected from the outside of the shuttle and varying between quite wide limits. This tension device presents no obstacle to the threading o eration, and its location in the shuttle is so -far from the tip of the bobbin that any failure of the holding means to maintain the bobbin properly centered has no effect on the roper operation of the tension device, an diminishes the chance of thread breakage if the bobbin is off center. Heretofore this has been sometimes comensated for by using an unduly large shuttle for a given length of bobbin, in order to give more freedom to the thread as it draws off over the bobbin tip, but I eliminate such a make-shift arrangement, the thread having ample freedom of movement around the bobbin tip and between it and the tension means. In practice the enlargement 39 is preferably wholly within the seat 4:0, so that no possible engagement with the thread can occur, and by utilizing the tension device to also hold the threading block in place I dispense with a separate holding screw or stud, simplifying and cheapening construction.

Referring to Figs. 1, 2 and 7, the head 2l is widest on aline drawn across it from the apex 33 of the depending portion 31, the width gradually decreasing to the beak, this decrease, in connection with the shape of the head causing a thread loop to draw outward and off the beak without breakage. That is, should a loop by chance be thrown outward and drop its bight over the beak the pull on the thread would draw the loo taut and slide it along the head, to the beak and then off the latter into the threading passage, without breaking the thread or unthreading it from the shuttle, the described action being permitted by the ta ering shape Vof the head and beak. Shoud the thread be. thrown outward from the tip of the bobbin behind and thence under the beak, forming a partial loop around the adjacentV portion of the head and thereby diminishingV temporarily the com lete control of the thread, the' pull on the latter will at once draw the looped part along the head and again into operative position without breakage of the thread or unthreading of the shuttle, which action, so far vas I am aware, has not been possible hitherto in automatically threading loom-shuttles.

In the specification and claims I have considered the front side or wall of the shuttle to be the one which is nearest the fell of the cloth, and the back or rear side or Wall to be the one nearestl the reed on the lay, and in the shuttle Vherein illustrated the thread delivery-eye is in the front side of the shuttle. The movement of the shuttle transversely to its length effected by the lay before the pick I term a backward movement, as at such time the shuttle is moved backward'.

bodily from the front of the loom. Such parts of the threading device as trend toward the front of the shuttle are indicated by the term frontward, while those parts which trend to the rear or back of the shuttle are defined by the terms lrearward or backward.

In order to distinguish between the entrance and eXit portions of the thread passage I have considered its entrance or inner end to be the one nearest the bobbin opening in the shuttle body, and its outer or exit end to be the one nearest the adjacent tip of the shuttle, and the direction of a part toward that tip of the shuttle is designated as outward while the term inward is used for the opposite direction. Thus, in deiining the beak I have referred to it as frontwardly and outwardly inclined, meaning rthereby that it is inclined toward the front of the shuttle and also toward the tip of the shuttle nearest the beak.

I have explained the novel features of construction and arrangement embodied in my l improved shuttle, one practical form of which yeaeoie broadly new inshuttles of this type to provide means mounted on the shuttle and relatively immovable to attain automatically an sertion of a bobbin, and having relatively immovable means mounted thereon provided with a thread engaging and directing portion to engage and assume deliverable control of the illing'thread upon relative movement of the shuttle and a part of the thread exterior' thereto in a direction transverse to the length of the shuttle.
