To all who??? it nuty concern.-

Be it known that we, EVERETT S. WOOD and J oNAs NORTHROP, citizens of the United States, and residents of Hopedale, county of \Vorcester, State of Massachusetts, have invented an Improvement in Filling-Exhaustion-Indicating Mechanism for Looms, of which the following descri tion, in connection with the accompanying awings, is aspecification, like letters on the drawings representing like parts.

In order to positively control and efiect a change in the operation of a loom when the filling in the runnin -shuttle has become substantiaTll exhauste or Woven off to a predeterminec extent, various instrumentalities or mechanisms have been devised and put into practical operation.

The change in the operation of the loom may be the automatic stoppage-thereof to enable manual replenishment of filling to be made, or it may be the actuation of mechanism to automatically effect replenishment of the running filling without stopping the loom.

Automatic filling replenishment may be effected by mechanism of the Northrop type, as disclosed in United States Patent No. 529,940 and other patents, wherein a fresh supply of filling is inserted automatically in the running shuttle of the automatically self-threading class without stopping the loom. Such looms are in extensive use, and we have herein illustrated one practical embodiment of our invention in connection with a loom of the Northrop type above referred to.

Our present invention has for its object the production of novel and eflicient mechanism to control and effect a desired change in the operation of the loom when the running fillingis substantially exhausted or Woven off to a predetermined extent, and, broadly considered, our invention comprehends purely mechanical control of the loom in ccntradistinction to electric or electromechanical control.

In the present embodiment of our invention the filling-exhaustiomindicating mechanism comprehends a mechanical feeler device governed and operated solely by or through means within the shuttle. the effective action of such device occurring when the running filling is exhausted to the'predetermined extent, taking place without contact between the filling in the shuttle and anypart of the feeler device.

The feeler device comprehends two movable members, one of which intermittingly impinges upon and is moved by means within the shuttle until the running filling is sub-. stantially exhausted, the second member,

up to that time inactive or passive, thereupon impinging upon other means within the shuttle and by such impingement becoming active and effecting the actuation of the loom-controlling mechanism.

An actuator, as it has been termed hereinafter, is mounted on one of said members and controlled by the other member, the actuator being ositioned inoperatively by the latter until t 1e predetermined filling exhaustion is attained, whereupon the member becoming active operates while the actuator is operatively positioned and the desired change in the operation of the loom is efi'ected.

As will appear hereinafter, there is no pressure upon the filling in the shuttle at the instant one of the members of the feeler device changes from passive to active condition a given forming-tool a constant radial distance or difference in diameter is insured between the barrel or step of the filling-carrier and its headthat is, the external diameters of the head and barrel will differ by exactly the same amount in any number of bobbins finished by the same forming-tool or duplicates thereof. Consequently it is as accurate to feel between the yarn or filling on the filling-carrier and the head thereof as between the filling and the part of the carrier on which the filling is actually wound. This we utilize in the preferred embodiment of our present invention, as will appear hereinafter. There is great advantage, moreover, in employing a feoler device sult is attained+-vizi a feeler wherein the actuating or active part or member nevercontacts with the filling, and especially in such a feeler device which ef-. fect's'a change in the operation of t'he-loont immediately upon contact with some means within the shuttle, such as the filling-carrier o,r something pertaining thereto. i

The construction and operation of-our present apparatus is such that premature action is impossible, and a much desired rede'vioe depend ingsolely on thefilling-carrier or means within the shuttleand 'at the same time the structureis exceedingly simple and certain ineits operation. v i v I In our invention noadjustment is required, for the relative position between the impinging faces of the members of the feeler device isin the first instance made and1adapt-' ed to the particular-form of filling-carrier to 1' be used. Furthermore, it matters notwhat shuttle is used, whether it be a little larger or a little smaller or whether theshuttle 'is new or nearly worn out. 7

As will appear hereinafter, the relative forward position of the shuttle in the shuttleboxv and the position of the lay at the end of its forward beat have no effect upon the acobtainable.

. tion, arrangement, andoperation of our joined specification and .running shuttle being shown invention will-be fully described 'in'the subparticularly pointed out in the following claims. g

When the rear end. of. the latch is moved .weft hamrfier, the forward movement ofthe latter pushes the latch forward and through arm d turns the. rock-shaft d in the direction of arrow 200, Fig. 2, to effect the operation of-the replenishing mechanism.

means which herein'govern the time of opering mechanism, but onlywhen the'running filling becomes exhausted to apredetermined extentfso that premature filling replenishmentha-nnot takeplace, while the actionis ,certainandpositive when the predetermined exhaustion is attained. p

As is usual in apparatus of thisgeneral character, the shuttle'hasa side opening 1 to register with the openingl K in the front wall 2 of the feeling or indicating shuttle-box 3, Fig. 1; i

The shuttle is shown ashavi'ng spring-j aws and in Figs; 1,4, and-5 we have shown a compound carrier comprising a skewer '5, having rings on its-butt 6, and a bobbinhaving a barthe skewer and be held in position by suitable catches 9, the jaws 4 engaging the rings on the butt 6. It is to be understood, however, that this compound filling-carrier is not of I fner se, and so far as concerns its behavior in ejected therefrom it diii'ers in no way from shuttle S, the controllingrjock shaftd to'efshuttle, the upturned armd fast on said rockconnections constitute loom controlling;

ationoffthe replenishing mechanism. The

' actuation ofsuch controlling means is effected by or through ,filling-exhaustion-indicat rel 7 and a head 8- andadapterl to slip onto 1 tion on theeline 8 8, Fig.1 ,taken' through the center of the feeler member} proper of the I feeler device, the parts being in normal posiinto position to be engaged bythe headof-the 4 (U engage and support the filling-carrier,

itself novel, nor do we make any claim thereto the shuttle or when transferred thereto or the ordinary one-piece bobbin or filling-carrier.

The barrel 7 and head 8 are accurately formed by a tool of the precise shape required, so that the difference in niameter between said parts is a constant quantity, and we avail ourselves of this fact in that emboiiment of our inventionwherein the feeling action is between the yarn or filling and the head, as will appear.

The holiing-plate 10 for the shipper S" has at its outer end a vertically-aajustable bracket 11, on which is secured a stand 12, preferably inclined at such an angle that the" feeler moves in a path closely coincident with the path of the lay A substantially as in our prior patent, No. 789,472, dated May 9, 1905, and as shown in Fig. 2. Said stand is con veniently made in two parts bolted together and chambered out at 12*, Figs. 8 and 9, to receive a transverse and rectangular enlargement 13 on one member, termed the carrier, of the feeler device forming a part of the exhaustion-indicating mechanism.

The carrieris made as a fiat elongated metal late 14, extending. rearwardly from the en argement or cross-head 13, a preferably cylindrical shank 15 extending forward from the latter and freely sliding through an opening in the front end of the stand 12.

The cross-head slides in the chamber 12 and is guided therein, a spring 15*, coiled around the shank between the front end of the stand and the cross-head, acting to project or move the carrier rearward to the position shown in Figs. 1, 4, 8, and 9, the rear end of the stand limiting such movement.

The body portion 14 of the carrier slides within a suitable opening in the rear end' of the stand, and the rear end of the carrier is laterally enlarged to form -a head 16, having a transverse impinging face or edge 17..

Upturned parallel ears 1-8 are formed on the carrier, which latter is longitudinally out out at 19 from the cross-head to the ears, leaving a transverse bar 20 between their bases, and beyond the bar the carrier is cut out or apertured at 21. thehead being longitudinally recessed at 22' to form a seat for and in which slides the feeler member, to be described.

An actuator is mounted on the carrier, and it is herein shown as an'elongated' arm 23, fulcrumed between the ears 18. on a'pin 24,

and having a short lug 25 depending below i the fulcrum, the actuator extending forward above the carrier and projecting above the top of the stand 12, as shown clearly in Figs.

8 and 9.

The th rd member of the feeler device and what may be termed the feeler proper, is mounted on thecarrer and has "a limited movement relative thereto. and .by or through such movement-controls the actuator. 23.1 -Herein the feeler is shown as an elongated bar 26, having a somewhat broader head 27, which fits slidably in the seat 22 ofthe carrier-head and rests upon the bottom thereof, the body portion of the feelerbeing disposed within the slot 19 and at its forward end resting on guide ribs or lec ges 28. (Shown in dotted lines, Fig. 4.) The .feeler is also slidably supported on the crossbar 20, Figs. 8v and 9, and is slightly for the purpose.

, The feeler-head 27 has an impinging face or edge 29 and a transverse recess 30 in its under side to receive the portion of the carrierhead 16 beyond the opening or aperture 21, the fore-andeaft width. of the recess 30 being such that a slight longitudinal movementof the feeler can'be effected with relation to the carrier.

A light spring 31, seated in a socket 32 in the carrier cross-head 13, bears against a shoulder 33 on the front end ofthe feeler, the strength of-the s ring being sufficient merely to project the eeler when unopposed into the position shown in Figs. 4 and 8.

A positive cohnection is provided between the feeler and the actuator 23 by introducing the lower end of the lug 25 between transverse ahutments or shoulders 34 on the body or shank of the feeler.

Owing to the eatdiflerence in lever-arms, comparing the ug 25 and the actuator 23, the slight forward movement of the feeler on the carrier is sufficient to elevate the tip of recessed the actuator a considerable distance above the top of the stand 12, as shown in Fig. 9.

By properly shaping the adjacent faces of the lug 25 and the rearmost shoulder .34 said faces come into parallel contact when the actuator is elevated, Fig. 9, or in inoperative position, thereby preventing said actuator from being unduly elevated and acting as a limiting-stop for the said actuator when it is moved into inoperative position.

-When the lay boxed in the shuttle-box 3, the feeler will enterthe shuttle and its face 29 will impinge upon the filling, and. the feeler will thereby first be moved forward upon and relative to the carrier for the slight distance permitted by the clearance of the recess 30 in the feelerhead. Then the continued forward movement of the lay will'move both feeler andbeats up and the shuttle is I carrier forward in unison'against the action of to position lnoperatively the actuator 23 by swinging the-latter into the position shown in Fig. 9, and consequently when the carrierbegins to move forward with the feeler the actuator is inoperative and so remains during that forward stroke. On the return stroke as the lay swings back the spring 15 returns or projects the carrier rearward to the full extent of its movement, Fig. 8, and as the filling recedes from the impinging face 29 of the feeler the weight of the actuator and the stress of the light spring 31 operates to reset tuator, as described, and then the feeler and feeler device.

carrier will move outward in unison, the feeler thus intermittingly impinging on and being moved by means within the shuttle, such means herein being the filling; but manifestiy the amplitude of filling-induced movementof feeler and carrier will gradually decrease as the filling diminishes and the distance between the barrel of the filling-carrier and the surface of the filling decreases. This gradual and intermittent diminution in the amplitude of the stroke of the carrier and feeler (movin in unison) proceeds until the filling in the s uttle is substantially exhausted or exhausted to a predetermined extent.

Referring to Fig. 4, it will be seen that there is substantially the same relative distance between the impinging faces 29 and. 17-

of the feeler and the carrier when the said members are normal as between the surfaces of the barrel and head 7 and 8 of the bobbin in the shuttle and that the face 29 of the feeler extends by that amount beyond the face 17 of the feeler-carrier. The smaller part of the filling-carrier is opposite the more extended part of the feeler device or barrel opposite feeler, while the larger part of the filling-carrier is opposite the less extended partviz., the impinging face 17 of the Aspreviously pointed out, the construction'of both fillingcarrier and feeler device can be made with the requireddegree of accuracy inthe .first instance, s9 that no adjustmentis left to the unskilled handling of the loom operator in the mill.

Ve have herein embodied our invention in such a structure that as the amplitude of filling-induced movement of the feeler member gradually decreases the distance between the impinging face 17 of the feeler-carrier and some means within the shuttle gradually decreases, so that when the desired or predetermined filling exhaustion is reached such face 17 will impinge upon the means withinthe shuttle. In Figs. 1 and 4 such means is the head 8 of the filling-carrier or bobbin, the slot 1 in the shuttle-wall being made long enough to permit ready entrance of the carrirr-head 16', with ample clearance. (See l i'g. 4..) As the face 17 is quite wide, a con siderable variation in the position of the shuttle in the shuttle-box may occur without causing the part 8 within the shuttle to move forward out of range of the impinging portion of the feeler-carrier. Furthermore, as the impingement of both feeler and feelercarrier is upon separate things, both Within the shuttle, and maintaining a certain relation to each other, it will be manifest that variations in the lay-stroke will have no effect whatever upon the operation of the feeler device. At the instant that the diminution in the diameter of the yarn mass permits the feeler-head to extend so far into the shuttle that there can be no filling-induced movement of the feeler the latter remains dead, inert, or passive on the carrier, and the actuator will remain quiescent and in its operative position, Fig. 8. The feelenpreviously active and by its action positionmg inoperatively the actuator and also maintaining the carrier passive, now becomes passive, while the carrier changes from a passive to an ac. tive condition, for it immediately impinges upon the head-8 of the filling-carrier and is moved' forward thereby as the lay completes its forward beat, the carrier and actuator moving forward together as a unit. The feeler is of course moved forward with the carrier; but the feeler is absolutely inert and non-contacting with the filling remaining on the barrel of the filling-carrier, the remaining filling being indicated at f, Fig. 4. Such filling remainder may be of any desired quan tity; but it is in practice at least suflicient to extend a couple of times across the .lay to insurea complete pick of filling in the cloth after exhaustion indication and before filling replenishment, reducing the waste to the lowest possible degree.

The change in the operation of the loom is effected by or throughthe exhaustion-indicating mechanism with absolute promptness and precision at the proper instant, and at such instant there is non-contaction between the filling and the feeler proper, or indeed, any part of the feeler device. The operation of the latteris dependent solely upon the filling-carrier in the structure so far described or on something closely pertaining to the filling-carrier and within the shuttle, as will be explained. There can be no premature change in the operation of the loom, however, for while there is sufficient filling within the shuttle to impart a movementto the feeler by impingement thereon suchmovement will inoperatively position the actuator, so that the loom operation cannot be changed until just exactly-the desired degree of filling exhaustion is reached. Until such time the feeler is primarily moved by impinging on the filling, while a secondary movement of the feeler-carrier-is effected through said feeler but when the latter noncontacts with the filling the feeler-carrier is moved immediately and primarily.

Means for causing the forward movement of the operatively-positioned actuator to effeet a change in the operation of the loom will be described; but as such means is substantially the same as shown and described the stand 12, the cam-slot 39 in said ear, and

crumed on the stud 42.'

the controller for the transmitter may be and are all as in our patent just referred to, the

as an arm 40, fulcontroller being shown The free end of the controller passes through the cam-slot 39,

under the guide 38, and across the top of" the stand 12, the end or foot 43 of the controller extending into the operative path of movement of the actuator 23, the tip of the latter being beveled at 45, while the rear 'edge of the root is notched at 44, Figs. 8 and 9. Nor mally the controller is in the low portion of the cam-slot 39, and if movement of the controller is effected toward the front of the loom it will act through the cam-slot to depress the adjacent end of the transmitter, rocking the latter on its fulcrum and movin the. latch (1- into position to be engaged an moved by the actuator or weft-hammer W. No movement of the controller 40 can be el- "fected so long as fillin -induced movement of the feeler inoperative y positions the actuator with its shar ened tip above the foot 43 of the controll er, and when such tip passes forward beyond the notched edge 44 of the possibility cooperate with and move the controller.

When, however, the predetermined filling exhaustion occurs, the actuator remains oploom-stopping mechanism constitutes means,

eratively positioned, as the f'eeler-carrier impinges upon means within the shuttle, and as the lay moves the feeler-carrier forward the tip of the actuator engages the notched edge 44 of the controller-foot, moving the controller. forward and first unlocking and then operatively rockingl the transmitter. A spring 46 acts norma ly to hold the controller in the low or rear end of the cam-slot 39, locking the transmitter in inoperative position. Either a filling-replenishing mechanism or a to control or effect a change in the operation of the loom, and the filling-exhaustmn-indieating mechanism governs the o eration of Instea of arranging the feeler device to cooperate with a compound filling support or carrier, such as is illustrated in Figs. 4 and 5, an ordinary onepiece filling-carrier or bobbin may be used, as

The operation of the leeler device does not difl er, however, from that already described, the filling impinging on the i'eeler until substantial filling exhaustion, and immediately the feelercarrier impinges on the butt 50, and the chan e in the operation of the. loom is etfectec We can also arrange the teeler to cooperate with the filling on the filling-carrier until predetermined exhaustion and the feeler-carrier to immediately impinge on the holding-jaws 4, as shown in Fig. 7, the only change required being in making the slot 1 in the shuttle-wall long enough to expose a per- When this arrangement is employed, it will be manifest that the distance between the barrel 52 of the fillin -carrier, Fig. 7, and the outer face of the hol ing-jaws is the critical distance, as it may be termed, and the normal distance between the impinging faces 29 and 17 of the Whichever arrangement be employed it will be manifest that one member of the impinges on and is moved by means within the shuttle, such as the filling, until predetermined filling exhaustion, and her of the ,feele'r device impinges on means also within the shutter, but other than. the first-named means or the filling, and thereupon a change in the operation of the loom is effected.

In each of Figs. 4, 6, and 7 the filling is supposed to have been exhausted to the predetermined extent, so that the other means within the shuttle is impinged on by the feeler-carrier or member of the feeler device which is not the feeler proper.
