14 Claims.

,Ti' isinvention relates to shuttles for weaving and especially to what, are called automatic shuttles such as are used in automatic bobbin,

changing looms. In this type of loom there is a battery, chute er -magazine which holds a numberof fullbobbins, one of which replaces an empty or almost empty, bobbin in a shuttle after a feeler located somewhere in the loom indicates that the thread on such bobbin is almost exha'usted. I

Generally the full bobbin is forced down by a transfer hammer into the shuttle, taking the place of an empty bobbimthe end of its thread being attached to some part of thebattery, magazine or to someother part of the loom.

the first pick, the shuttle carrying the new, full bobbin is driven across the loom and on the next pick it is driven back. In shuttles where there is a shuttle eye outlet in the side, the thread cannot get permanently into the eye out,- let so that it is permanently trapped, until the second pick after transfer, because it must get around a nose and changeidirection almost ninety degrees. i

1 Most such shuttles have a nose extending forward at or near the top of the shuttle with ahook of some sort extending ldown near'its top so that on the first pick the thread drops down under this nose and is caught by the hook. There is also what is known as a horn'which extends :down and back from at or near the nose, this horn having a hookat the bottom, the purpose being to cause,

the thread on the second pickto slip down along the front of the horn behind this hook into a thread delivery passage to an eye outlet where it will be kept by :the hook, as a, trap, while the thread on the new ibobbin is running out.

There is also a central vertical inside thread postaround which theflthread bendslat an angle of about ninety degrees. r

Ordinarily'there isan axially extending threading slot and .a top thread groove in front of it. There is also an eye threading slot extending down and back at an angle from in front of the nose to a shuttle eye outlet.

With mydevice, there is no axial, forwardly extending threading slot, no top groove, no vertical, central inside post, no nose, no horn, and no angularly backwardly extending eye threading slot.

The main feature of my 'device is a single threading slot and thread p'assage which extend from the front of the "bobbin chamber straight and diagonally toward and out "the Side 0f the shuttle into a thread groove as a shuttle or thread eye outlet. u

The thread delivery eye passage forms part of this threading slot or connects with that slot at its bottom, both the slot and the thread delivery eyepassage being substantially straight.

Another novel feature of my device is the trap at the thread or shuttle eye outlet, which outlet is at the front end of the threading slot and of the thread delivery eye passage. The purpose of this construction is to cause the thread to slip down into and through ;the threading slot right into the trap and into the thread delivery eye passage and shuttle eye outlet on the first pick or at almost the instant the shuttle starts to move along the shuttle race on the lay on the first pick after transfer.

7 This shuttle eye outlet is so made, preferably with two vertical outlet pins, that as soon as the threadis in the trap it remains there and runs between these outlet pins until another bobbin is transferred. In other words, it is fully and finally threaded, r

I alsoprefer to provide the thread passage at its inlet with friction plates which also serve as thread guides or with a thread pin so placed that the thread makes no bend and touches: nothing after leaving the plates or pin until it runs around one of the Outlet pins into the thread block is used in a shuttle body made of wood or other material, with my device many parts are eliminatedand many processes are avoided because I Qan use a threading block with substantially parallel sides, bottom and top, which block can be slipped in at an angle from the eye side to a sim larly bored and cut block recess, or hole.

Moreover, the thread delivery passage in the block can be drilled as a straight, cylindrical hole and the threading slot can be cut as straight passages with a straight saw. a

The threading block can be held in place by suitable wings, ribs and grooves of different kinds and by a blockscrew in such a way that-they do not Weaken the shuttle.

By omitting the usual threading slot which runs axially and beyond which is a top groove, there is more stock at the front of the shuttle and the tendency to split at that point is greatly reduced.

The wear pins at front and back at the eye outlet can be made of very hard metal, porcelain or other 'wear resisting material and can be held entirely in the metal threading block instead of in the wood thereby rendering the construction stronger and allowing them to be easily replaced.

The entire construction of the threading block is much simpler than where an axial threading block with wings sunk in the wood, a forward nose, a horn and irregular passages is used as in the usual construction.

By making the sides. and bottomof the thread ing block cylindrical, it can be slipped into a drilled hole in the side of the shuttle body and as in this construction the block is held on they sides, part of the top and at the bottom, it does not rock on the attaching screw and cause trou desirable to help balance the shuttle, my device canbe used as part of a shuttle made of plastic or other material with no block of any kind.

A shuttle of my construction can of courseloe V threaded by hand.

In the drawings, Figs. 1 to 10 show a shuttle with a, preferred form of removable threading block.

In the drawings, S represents a shuttle of the automatic type having a tip I which I will call the front tip, a thread groove 2 along the side of the delivery eye passage outlet 2| and a bobbin recess 3 in which a bobbin B is shown as held by the usual holder ll, l2 representing the tip of the bobbin.

The above parts are substantially the same as in most automatic shuttles, the thread groove 2 which runs along the eye outlet side of the shuttle being to receive th thread T after it has com from the bobbin B and out through the eye, all in a well known manner.

' 4 represents a threading block recess which extends; from the middle front IU. of. the bobbin recess 3 diagonally forward to a position atthe eye side and at the thread groove 2 between the front tip and the front ll] of the bobbin recess 3.

As shown in Figs. 1 to 7, there is a mouth E,

to receive the thread '1, at the top of this block recess, formed by the wooden lips at 5, '5, which converge and extend downwardly while the sides 6, 6, are'parallel and the bottom at is substantially cylindrical in cross section.

A represents athreading block which in cross section substantially conforms to the shape of the block recess 4 whereby it can be slipped in fromthe outsideor slipped out if it becomes necessary to remove it. c 1

The front'part H) of bobbin recess 3 enters block recess 4 and Hi is a recess for friction plates}, 9, if they are used, and may be considered-an extension ofor part of eye passage 20. The eye passage 20 extends lengthwise through the thread block A, parallel with its side and bottom walls, from the back or inside end I9 and the recess H? for th friction device G, including the plates 8 and 9, to its outside end 2| which I will call the eye passage outlet. At this end just inside the outlet 2| is the thread trap V which includes a hook 23, thread passage 28 and trap thread guide 21.

Where a block such as A is usedE indicates the mouth which includes the converging lips 5, 5, in the shuttle bodyand'the lips 25, 25, in the block A. a This mouth and these lips are so made that-they so 'converge'as to direct the thread T int-o the'threading slot C and trap V. This threading slot C includes the part 22 which extends from the middle of the top near the back of eye passage 2!) forward and preferably at a slight angle away from the eye passage outlet and down at a tangent or near tangent to the front'of that passage just behind the trap V as shown'in' Figs. l'and Z'and 4 to 7 This part 22st the slot '0 stops just before it reaches the trapthread guide 21 and turns at 28 at about a right angle between the trap hook 23which is formed when it is being cut and the trap thread guide 2|,*Figs. 1,'4A, 6 and 7. 1

It will be observed that this trap thread guide 21 blocks the front. end of the part 22 of the threading slot C and that at the front or outlet end of the'block A, the lips 25,25, merge with the top faces or edges of the trap hook 23 and of trap thread guide 2Twhich'faces are preferably formed on, curves which slope in and down in opposite directionstowards each other and which intersect at a point'slightly above the thread center by the transfer the thread T is directed by the mouth, suchas E, intotheback endof the threadingslot C and when once started in that slot, thefiensionpn the thread as it partly untrap thread guide 21.

winds from its bobbin to the point where it is attached to the magazine, causes it to slip along lay moves from front to top center, the up and down movement of the thread as it unwinds, beingconiined betweenplates such as 8 and 9, and

the snap of the picker action combined with the backwardmovement of the lay, carries it down around-and under both parts of thetrap V namely the hook 23 and the guide 21 and through the slot part 28 into the eye passage 20 although usually the hammer action of the transfer itself causesthe thread to get into the eye passage before top center.

Where a threading block is used, Ifind it convenient to cast it with the sides of the threading mouth converging and extending down to where the threading slot will be cut. The front part where the thread trap willbe is also suitably formed.

The eye passage 20 is bored or drilled, preferably parallel with the sides of the-block, the parts 22 and 28 of slot are cut down into the eye passage, with 28 at a right angle as in Fig. 1 or at t l a different angle asin Fig. 13. The out part 28 forms {the trap hook 23 and separates it from the The thread groove 26 is cut and holes I6 and I I for pins P and F are drilled upfrom the bottom-across groove 25 where it intersects passage 20 and all sharp and rough edges are removed.

Extending down from under the thread guide 21is a vertical front outlet p'inF which extends across part of the thread groove 26 and across the front part of :the eye passage outlet 2|.

P is a vertical back outlet pin which extends across part of the thread groove 26 and across the back of the eye passage outlet 21 and 8 and 9 representfriction plates of a well known kind which slope forward and downand at the top have diverging lips I5, IS, in a position to receive the thread as soon as it starts unwinding from the tip 12 of the bobbin B on the first pick. These plates and particularly the one 9 on the eye side keep the thread T in the middleo'f the eye passage 20 until it engages either one of the pins F or P. After it leaves either one of these pins, it continues in the thread grooves 2 and 26 at no place coming in contact with any rough surfaces which might injure it.

D is a'fastening screw which as shown in Figs. 1 t0x10 passes down through a hole 28A in threading block A and into a nut 29 sunk in the wood of the shuttle S. l

Blates ii and 9 of friction member G are movable on a pin I3 and are pressed together by springs I4, 14. Pin i3 holds up thread T clear r of the =bottomof eye passage 20.

the threading block construction in which the block :is indicated by 0. Its cross section, as

shown in Fig. 11, is relatively rectangul'ar instead ofcylindric'al-as is also the recess 4| into which The "body of the shuttle is cut away at ,40, and the opening and lips 42, 42, of the threading slot 43-all converge to direct the thread through-thethreading slot 43 and into the thread delivery eye passage M. r

The trap hook 45 and thread guide 45 are substantially the same as in the other construction but the attaching screw 41 passes through the horizontal hole 49 in the body and 48 in the block instead of extending down vertically.

In Figs."14, 15, 1'6, thethreading block K is shaped in cross section very much like A but on each side has the longitudinal grooves 50, 50, which engage the ribs or projections 5|, 5|, extending into the block recess 52 whereby the block-is locked in place. The converging lips 56, 56 in the wood may be small in this case. The converginglip's 54, "54 are all that is necessary and the fastening means is shown as two vertical screws or pins 55, 55, which extend down from the top of the block through the projections 5|, 5|, thereby locking the device entirely and firmly in place.

As shown in Figs. 17, 18, 19 the threading block may be entirely omitted as Well as the friction plates and the outlet pins. In such a shuttle H, the lips 60, B0, connect with the threading slot 6| which enters or forms part of the thread delivery eye passage 62 with a trap hook 63 and thread guide 64, the outlet pins being replaced by rounded surfaces 65, 65, and the friction plates being replaced by felt pads El, 61. Preferably there is one rounded guide rib 65 at the inner end of passage 62 on the eye outlet side.

The characteristics of my device are that my threading slot starts atthe middle top of the front of the bobbin chamber so that thread, wound either way, will slip into it as soon as the lay starts to move back, or even before that if I use a friction device of the friction plate type with the friction plates sloping down and forward, as the thread is instantly caught and is held in line with and starts through the back of the threading slot.

The slope of the mouth such as E, at the back or near the'bobbin tip, down to the back entrance of the threading slot should be at a steep angle, the front or eye side being preferably steeper than the other side, as shown in Figs. 8, 9, and 10.

While preferably my threading slot extends from the back, forward and down at a small angle with the axis of the thread passage away from the outlet side so that the thread after it starts in the slot is being constantly pulled down until it engages the thread guide which extends from in front of the end of the threading slot out and down beyond the front and bottom part of the trap hook formed by the cutting of the threading slot, this threading slot may run parallel with the axis of the thread passage, provided the'thread guide extends in front of it over and down below the trap hook so formed whether it is down at the sidenear the bottom or at the top.

As my threading 's'lot starts at the middle top, the whirling or unwinding of the thread from the bobbin is of no help nor hindrance except that as the thread unwinds, it moves up and down between the friction plates and the downward motion, when combined with the diagonal pull along the axis of the thread passage as the lay moves back and the shuttle starts its pick, carries the thread down through the threading slot, around the trap hook and down over the thread guide until it is safely locked in position,

On account of the shapeof the trap hook and its association with thethread. guide it makes no difference which way thethread-shpsaround the eye outlet, as it willbe stoppedby the thread threaded, will slip down below. and betweenit' and the bottom of the cooperating trap hook or will slip down off the trap hook, around the tip or nose of the thread guide but cannot escape. W

The top faces of thetrap-hook and; of the trap guide curve or slopeso that they intersect and the bottom face of the guide comes below the tip of the hook as shown enlargedand exaggerated in Fig. 25. V

In Figs. 20 to 24, I show various combinations and modifications of the threading slot, thread passage, trap hook and thread guide. I

In Figs. 1 to 10, slot 22-is at an angle with the axis of passage 20, and hook 23 is at the right as is guide 21.

In Figs. 20 and 21 the threading slot 32 or 82 is at the top and parallel with the axis of thread passage 30 or 80, so that hook 33or 83 and guide 3! or 8'! are near thecenter of the eye passage and in Fig. 22 the hook 84 and thread guide 85 are over at. the left. p r

a double thread delivery passage formed'by holes 99 and 9| connected by a secondary threading slot 92, the primary threading slot being shown at 93 and forming the trap hook 94, while the thread guide 95 extends well down beyond and in front of it.

' In Fig. 24 is shown a double thread-passage formed by holes 96 and 91 connected by a slot 98, while 99 is the threading slot connecting with and forming trap hook I in front of which extends the thread guide IOI.

In my preferred construction, where I use a metal threading block extending diagonally such as A, O, or K, to keep the shuttle well balanced, leaving the front part of the shuttle near the tip with more wood or other material than in the usual construction, I bind the shuttle'body and block together by a bolt or screw. I thus secure a stronger construction and one which will resist the constant pounding of the loom.

If the block such as A, O, or K is inserted through a hole in which the material of the shuttle body overlaps part of the block or if one or the other has ribs or channels, any tendency of the block to loosen and pivot on the fastening device is stopped.

Fig. 25 is an elevational view and Fig. 26 is a horizontal sectional view, both diagrammatic ,and

enlarged, of a typical outlet of a thread eye passage showing the preferred shapes and positions of the trap hook and guide and of the outlet pins such as P and F with reference to a thread eye passage such as 20 and a thread groove such as 26,'which forms part of'the thread eyegroove such as 2 in the body of the shuttle.

Fig. 26 clearly shows that, preferably, pins P and F or their substitutes 65, 65, are so positioned that they intersect the walls of 20 and 26 so that each projects a little distance into both the.

eye passage and into the thread groove.

Preferably the bottom edges of the thread trap hook and guide are in the same curve, and the bottom edgeof the guide should not be above assmss thejbottom edge of the hook but itmay extend below that edge and down in front of thetoppart of the eye passage, and of, course it: should be outside and spaced fromthe trap hook.
