'Specification of Letters Patent. -Patented J al1. 14, 1919.

Application filed August 31, 1917. SerialNo. 189,106.`

To all whom t may concern:

Be it known that I, JoznF Go'rERoH, a citizen of Austria, residing Vat Lawrence, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Filling -Feelers, of which the following is a specification.

This invention relates to filling feeler devices for looms. Its object is to provide means which will permit as much as possible of the filling on the bobbin in a shuttle to be used before the filling is replenished whereby there will be less filling wasted. It is more particularly adapted for looms in which the filling is automatically replenished, as by the substitution of a full bobbin for an empty one, but it can readily be adapted for use with almost any type of loom.

My device is especially useful on looms in which there is a battery of bobbins which are introduced one after another into a working shuttle. Such looms have a lay beam with a shuttle race and shuttle boxes with lling changing mechanism operative by a movable shifting arm. This shifting arm, whenever it is moved in a predetermined manner through the medium of devices of well known construction operative by feeler mechanism, operates ina well known manner to start the filling changing mechanism which, without stopping the loom, ejects the old bobbin and replaces it by a new one.

My invention relatesespeciallv 'to feelers which yoperate vertically into or through the bobbin recess in a shuttle. With my device there is no need of cutting a slot through the side of the shuttleV to permit the feeler finger to enter as the feeler comes down from the top "into the bobbinv recess. In my preferred form I use a caliper feeler the legs of which come downon both sides of the bobbin and which can be very accurately adjusted.

My device has few and simple parts `and can readily be attached to any of the ordinary looms. It can be adjusted with great accuracy, but has no delicate springs the Strength of which is' likely to vary. It cannot easily be injured by binding on the shuttle, by the shuttle rebounding, or by any Yof the various accidents which occur in the operation of looms.

It is so arranged that it cannot bind on the bobbin and will not be injured if the shuttle binder does not work and the shuttle rebounds. Y l

By a very slight change in v,the shape of my feeler shaft, it can operate .various types of shifting arms lsuch asthose which lare movable horizontally or vertically. vI prefer to use it in connectionwith a vertically movable shifting arm. I also prefer to use in connection with my caliper, an auxiliary feeler which may consist of a Vsingle blade at a distance from the main caliper Vsuflicient to reach the middle part of the bobbin. v

Such auxiliary blade I nd is of advantage inconnection with'bobbins ,which are defectively wound as on suchv-bobbins the usual type of feelers which operate inone l place only, are not satisfactory. Y

By sorting out the defectively` wound bobbins and using them in a loom provided with my auxiliary feeler, I can save a considerable amount vof filling which otherwise would be lost. In this manner, the process of rewinding such bobbins is done with.

If it seems desirable, in place of calipers, I can use in connection with a bobbin which has a longitudinal slot, a feeler which consists of a single downwardly extending blade in position to` enter the slot after the yarn has run out, provided the 4bobbin is'I so turned that the slot is vertical instead of horizontal.

When used with a loom having a battery, magazine, or boxes at one side, I prefer to -.locate my devices at the opposite side.`

In the drawings, Figure 1 is van elevation from the front of the loom showing my de-Y vice in connection with a layV beam, shuttle andl other parts with which it is in operative relation. Fig. 2 isa sectional elevation Yfrom the left on line 2 2 of Fig. l. Fig.

3 is a plan view of the feeler shaft and accompanying parts with an auxiliary feeler v in place. Fig. 4 is an enlarged view from the right of Fig. 3 on the line 4-4e Fig. 5 is an enlarged view similar to Fig. 4 with the spring plate and spring removed. Fig.

6 is an enlarged detail elevation of the feeler .Y

8, 9, and 10,'show different modifications of the knock-olf arm to adapt it for operation with different types of shifting arms. Fig. 11 shows another modification in which an independent knockoff arm is shown as attached to the slide stripV through the medium of the hub and feeler shaft. Fig. 12 is a detail view similar to Fig. 7, showing a single feeler member in connection with a vertically slotted bobbin. Fig. 13'is an elevation and Fig. 14 a plan view of my device adapted for a loom in which there is'no automaticv` lling replenishing mechanism, but wherein the 'shifting arm is arranged merely to operate filling changing mec anism to stop the loom.

In the drawings, M represents the lay, R the shuttle race thereon, A a shuttle box at one end thereof, P a picker, and L a plate attached to and forming part of the lay beam. In this plate L is a vertical slot 19 in which there is, vertically slidable, a slide strip 20. The strips 10 and 11 `hold this slide strip in position and it extends upward to a. point above the shuttle race, and also down below plate L as shown.

` Fixed to this slide strip is a feeler shaft 73 which extends across and over the shuttle race. To this feeler shaft in a. position to rock lengthwise of the lay beam is pivoted the vertically operable feeler mechanism to be described.

This slide strip and shaft carrying the feeler devices, are associated with means independent of the'shuttle to permit them to to drop and to lift them just before the shuttle is picked. Such mechanism is shown as including a connecting rod 22 pivoted to the slide strip at 21 and bent in any suitable fashion to clear the other parts of the loom. Its lower end is substantially vertical, and adjustably the guards 23 and 24.

Fixed to any part of the loom frame such as 37, by means of a frame 36 and a bolt 38, is a standard 35 to the top of which at, 33 is pivoted a rocking arm T which extends out around the rod 22 between the guards 23 and 24. This arm T may have a horizontal spring rod 40 extending from it connected to one end of a lifting spring 39, the other end of which is attached at 41 to another part of the frame ofthe loom.

lTo arm is fixed a projection 32 which extends int-o the line of travel of a cam F attached thereto are carried by any convenient shaft 30 which y and slide 2O will keep the feeler shaft and feeler raised away from the bobbin. At a point which is predetermined so as to be just as the shuttle is entering the shuttle box; on the side of the loom away from the battery, cam. F depresses arm T against spring 39 allowing the feeler arm and feeler to descend'by gravity.V Just before the shuttle is picked, cam F is Vso made and timed that projection 32 slips off allowing spring 39 to act in such a manner that the feeler shaft and feeler are suddenly kicked up out of the way of the shuttle.. This kick is in the nature of a'blow and tends to release the feeler mechanism in case it might otherwise be jammed or bound'onV t-herbobbin.

VThe feeler mechanism includes a hub H pivoted on the feeler shaft, and a caliper feeler which includes one leg 52 integral with hub H, and another leg 53 which is' shown as extending up alongside of hub H, and as being pivotal on the feeler shaft and extending Vdownward parallelwith leg 52.

The part 53 is attached to the hub I-I by means of a screw 55. This screw 55 may be Yes headed and have the usual slot for a screw driver. It is shown as Unthreaded where it passes through hole 57 in the hub and as threaded the rest ofthe way to its tip. It

also has an annular groove 56 with which a Y Pivoted onV feeler shaft 73 is a spring plate 71 which extends downward and is slotted at 81 so as to pass snugly around screw 55 as shown in Fig. 4 and Fig. 6. A returning spring 5l at one end passes through a hole in shaft 73 andat the other end into a hole Y in spring plate 71, whereby as the parts are held together by `screw 55, the spring tends t0 return them when they are'turned against its pressure. This spring is preferably 'of helical form and longV enough to permit of considerable compression to allow the bracket which carries theV supplemental feeler 60 to be inserted between the spring plate and legr53. Its pressure'holds these parts together.

To hold the hub inV osition on its other side, I usea collar 77 wiich is fixed to shaft 73 by means of a projecting set screw 78. I Y

prefer to so locate this set screw that it will project into the path of the upper back corner 74 of leg 52 and serve asa stop-to limit its movement from the pressure of spring 51, whereby it will be held normally in such a position that the caliper feeler formed by- V legs 52 and 53 will be directly'over the bobbin B in the shuttle S.

As shown in Figs. 1, 2, 3, 6, 7, 8, and 9, the feeler shaft after it passes the hub isr integral with and forms party of a knock-off arm.

This knock-off arm can be bent in various ways, as shown in Figs. 8, 9, and 10, as well as Figs. 1, 2, and 6, so as to be in operative relation with the shifting arm which stops the loom or which changes the filling as, for instance, by ejecting ,theV bobbin from the shuttle and replacing it by a new one.

In Figs. 1, 2, and 6, this shifting arm 84 is shown as located under the knock-ofi' arm and as operable when it is pushed downward by the weight thereof.

In Fig. 8, 100 represents the uptur-ned slanting tip of the knock-0E arm, and 101 the shifting arm which, as shown bythe dotted lines', will be forced crosswise of the lay beam when the arm descends.

Fig. 9 showsvthe tip 102 bent at right-an;

gles and angularly so that when the knockolf arm descends, it will force the shiftingarm in a direction lengthwise of the lay beam, as shown by its dotted position, from its full line position 103.

Y In Fig. 10, I show the tip 104e of the' down, to the right or left, or toward and from the lay beam.

As shown in Fig. 11, I may use separate Vmembers for the feeler shaft shown as 108,

which is cut `of beyond collar 77 and the knock-oil' arm 106, which is shown as attached to hub H by means of a screw 107.

I findit desirable with certain 'bobbins, es-

pecially those which are defectively wound in such a manner that the 4yarn unwinds from the part near the head where my calipers ordinarily engage the bobbin, before it unwinds from the middle part, to use an auxiliary feeler which will hold up the parts until the yarn at the point where itl operates has also unwound.

I lind it convenient to equip one of a number of looms with such feeler and to use up all defective bobbins therewith. I arrange my device so that this feeler can be readily attached or removed as I will now describe.

I provide a bracket 59 which is preferably formed of an angular piece of sheet metal with a vertical extension 146 in which from the top there extends downward a slot 145 of such size that it will readily slip upward over shaft 7 3, and at the bottom a slot 80 of such size that screw 55 will pass through it with a running tit.

The other part of bracket 59 extends ou in al direction toward the middle of the bobbin and has near its end a slot 147. The eeler preferably includes a blade 60 of the thickness of the caliper portion of leg 53 VVshaft 7 3 and then twisting or pushing it to the left so that slot 80 passes over screw 55, and then allowing spring 51 to bring the parts back to their normal position.

Vith my construction, by adjusting collar 77 and screw 55, my calipers can be made of any desired size and located directly over the center at one end ofthe bobbin and as the whole mechanism is permitted to drop by the cam and accompanying parts at the time when the shuttle is stationary in the box, it' properly adjusted the calipers will stop. at the point shown in Fig. 2 until the yarn has been unwound to the predetermined point, after which the calipers, hub, knockoff arm, etc., will drop to the position shown bythe dotted lines in Fig. 6, thus operating the lling changing mechanism.

My device avoids the objection to some other caliper feelers that if they strike the wood of the shuttle, in case it rebounds too far, damage is done, as no injury occurs ii the wood is struck. Moreover, if the shuttle binder fails to work and the shuttle reboundsl after the calipers have engaged the bobbin, no harm is done as the calipers are thrown up out of the way, as shown by the dotted lines in Fig. 7, and are Vquickly returned to operative position by spring 51.

Vspring 39, or if the spring should break or should be too weak', the hub and calipers, being` pivoted to rock lengthwise .of the lay beam, will be swept out of the way by the movement of the shuttle. f l

It is evident that instead of extending the knock-ott arm to reach the shitting arm, the shifting arm could be lengthened or bent in order to reach thel knock-off arm.

TWhile I prefer to use two-legged calipers in connection with a bob-bin which has no slot. thereby saving the expense oi forming a slot in the bobb'in, I may however, as shown in Fig. 12, use for a feeler a single Cil blade 150 in connection with a bobbin such as 151 with a slot 152 which is turned to the vertical position instead of the horizontal.

1With such an arrangement, when the yarn 153 which, as shown, extends across the slot in such a manner as to keep the blade 150-out of slot 152, runs out to such a pointthat the blade is allowed to fall through as shown by the dotted lines, the shifter arm will be operated in the same Vmanner as when the caliper feeler is used.'Y

In such a case, however, guard 23 should be so adjusted that the blade cannot go too far into the bobbin, asy it mightfpossibly catch in the slot and prevent the shuttle from sweeping it up ont of the way as shown by the Vdotted lines, if the lifting springs should fail to act. Y

My invention covers a downwardly depending feeler free to move vertically and adapted to rock lengthwise of the lay beamV and means independent of the Vshuttle to permit it to drop and to lift it just before the shuttle is picked.

By the use of the term filling changing mechanism in this specification, I intendto cover broadly any mechanism which will act either to automatically replenish the filling by changing the shuttle or bobbin, replacing either by a full one without finally stopping the loom, or mechanism which merely stops the loom so that the filling can be changed by hand.

I show such a construction in Figs. 13 a-nd 14 which represent one end of the breast beam at one side of a plain or fancy loom. When used on a fancy loom, I prefer to place my devices at the side opposite from the boxes.

160 is the breast beam, 161 the shipper handle which, when the loom is running, rests in a notch 164 from slot 162 in guide 163, 172 is the slide, 170 the filling fork fingers, 171 the weft hammer, 175 the shipper knockoff lever, all of well known construction.

To the breast beam at 185 preferably over the knock-off lever, I pivot a member having an arm 187 adapted to engage the shipper handle and to move it to stop the loom, as shown by the dotted lines, and an arm 186.

' To arm 186 I pivot a tip lever K one end of which 183 is the shifting arm and extends out under knock-0H' arm 73 while the other end 182 which is the heavier rests normally on stop 184.

To weft hammer 171, I attach a nger'180 with a head 173 which extends out sidewise and normally moves back and forth with kthe weft hammer over the end 182 of the tip lever. IVhen the yarn has almost run out, my feeler drops, and arm 73 engages shifting Varm 183 by bearing down on it. This lifts end 182, as shown by the dotted lines dotted lines in Fig. 14, thus moving shipper 161 to stop the loom.

Wy device does not interfere with the feeler fork mechanism for stopping the loom when the filling breaks, but also stops the loom just before the filling on a bobbin runsk out, thereby making it unnecessary for the Vweaver to turn back the chain to locate the pick.V Y
