To all whom it may concern:

Be it known that I, FRANKLIN ALLEN, a citizen of the United States, and resident of l/Valtham, county of Middlesex, State of Ivlassachusctts, have invented an Im rovement in Filling-Exhaustion-Indicating lechscription, in connection'with the accompanying drawing, is a specification, like letters on the drawing representing like parts.

This invention has for its object the production'oi novel filling-exhaustion indicating mechanism for looms whereby the detection of substantial exhaustion of filling in the running shuttle is made effective to cause a change in the operation of the loom, such for instance as its stoppage automatically or the automatic replenishment of therunning filling. i

The operation of the mechanism embodied in my present invention is based upon the relative penetrability of the' filling mass and the material of which the filling carrier or bobbin is composed and upon which the filling is wound, and while broadly this principlc is found in United States Patent N 0. 823123 granted May 22, 1906 to C. F. Roper,

different from the invention forming the sub ject matter of'this application. Herein the said members moving unison until sub stantial filling exhaustion is reached. Therenpon the penetrating member is moved, by engagement with the filling-carrier, relatively to the impinging; member, such initial relative movement releasing the members, which up to that time have been locked together. When unlocked a secondary or ef-- festive relative movement is imparted to the penetrating member, causing the desired change in the operation of the loom through Until the secondary 1novement'.is effected the feeler de-' vice is dead or inactive with respect to the instrumentality which causesthe change in the operation of the loom, an actuator re maining inoperative throughout the time the 'ieeler device is dead and being operatively positioned and rendered active only when the eli'ective movement of-the members of the present invention is Wholly different from the a paratus disclosed in the Roper patent a ore'said, wherein an actuator 18 inoperatively positioned on each detecting pick until the-predetermined fillin cxhaustionis reached, such positioning of t e actuator being efiected by a relative movement of the feeler members while sufiicient filling is present in the shuttle.

The various novel features of my inven-- tion will be fully described in the subjoined specification and particularly pointed out in t efollowing claims.

Figure 1 is a top plan view, centrally broken out, of a suiiicient portion of a loom, with one embodiment of my presentinvention applied thereto; top plan view of the feeler device in normal condition, with a filling-carrier and filling Fig. 2 is an enlarged mass thereon, the filling being shown as reduced to such an extentthat the feeler device is just about to be operated to cause a change in the operation of the loom; Fig. 3 is a side elevation of the feeler device, view-- ing it from the left hand side of the loom, the parts being in the condition shown in Figs. 1 and 2; Fig. 4 is a view similar to Fig. 1 but showing the fe eler members after they have been moved relatively to operatively position the actuator; sectional detail on the line 55, Fig. 4, Fig. 6 is an enlarged detail on the line 6*6, Fig. 1, looking toward the right, and Fig. 7 is a detail of the front end of the latch-carrier and the feeler-controlled lifter to cooperate therewith.

The breast-beam A, lay'A, filling-feeder F of the replenishing mechanism to hold the filling-carriers or bobbins b on which the mass of filling is wound, the transfe'rrer f and the controlling rock-shaft d are and may be of well known construction in automatic filling-replenishing looms, the shipper N and its notched holding-plate N, the. knock- Fig; 5' is a longitudinal of? lever n, n and the shuttle S, Fig. 1, havi'ecler device occurs. In this respect Inyl mounted on a latch-carrier fulcrumcd on a.

slide 0 adjacent the guide for the slide m of the usual fork m the weft-hammer W acting to move the slide outward upon filling failure, to thereby operate the lmockoff lever n n and release the shipper.

The latch-carrierhas a foot 0, to be referred to hereinafter, and a spring 8 Fig. 6, normally acts to elevate the latch c above the path of a shoulder w on the weft-hammer, the structure described being substantially as shown in the Marcoux patent, but 0 erating in a slightly different manner. hat

3 is,- in the patent a device is intermittingly movedbeneath and awayf'rom the foot 0 until redetermined filling exhaustion is reache and, at such timesaid device remains beneath the foot when the weft-hammer W moves forward to, effect engagement between the shoulder w and the latch 0*, but herein the foot 0 remains down and the latch .u until filling replenishment is called for, an then the foot is lifted, as will be described, to lower the latch into operative position.

When

so lowered the shoulder to? engages the latch 0 and the slide a is moved outward,

shank between the rocking an upturned arm (1 fast on the rockshaft d", turning the latter and effecting the operation of the replenishing mechanism in well known manner.

Upon the outer end of the plate N I secure a stand 5 having bearings 6, 7 to receive and slidably su port a carriage 8 having a cylin-' body 13 and a lateral, broad head 14,which' presents a face 15 to intermittingglenter the shuttle and impinge upon the ing mass therein. p

The body 13 is provided with longitudinal slots 16, see Fig. 5 through which are extended screws 17 and 18, into the part 12 of the carriage, the screw 18 clamping the feeler member 13 to the carriage while. longitudinal movement of said member isp'ermissible, a stop-screw l9 and checknut 19 helping to maintain the adjustment and also to effect a fine adjustment when the clamping screw 18 is slightly loosened.

i. The screw 17 is made'long enough to extend-through and form a fulcrum for an actuator, shown as an arm 20, mounted to swing laterally above the feeler member13, said actuator being bent upward as-shown in The end of the actuator adjacent its fulcrum is widened laterally and provided with aslot21, to receive a leg 22 extended upward from the penetrating member 23 of the feeler device, shown as an elongated and flat metal bar having at its rear end a pron 24.

The penetrating member is s lidably supported on the part 12 of the carriage, a ainst the adjacent upright and longitudina edge of the body 13 of the'impinging member, and is held against it by means of a latch 25 fulcrumed at 26 on the part 12 of the carria e, andacted upon by a suitable spring 27, t e s ring at all times acting to press the toe of t 1e latch against the side of the penetrating member 23. Said member has on its outer side a cam portion 28, and slight notches 29 and 30 are formed in its edge at the opposite ends of the cam surface 28.

Referring to Fig. 2, the normal relative po- .sitionv of the impinging and penetrating members of the feeler device is shown, the toe at such time entering the notch 29, and holding the penetrating member from any movement relative to the impinging member, and at such time the prong 24 extends slightly beyond the contact face 15 of the impinging member. On every alternate ick, when the shuttle is in the sl1uttle-b0x Fig. 1, the feeler members enter the shuttle through the a ertures 3 and 4, Fig. 1, and cooperate with t e mass of filling on the filling-carrier or bobbin b, and the face 15 of. the im inging member impin es upon the filling, w ile the iplrlong 24 slight y penetrates or sinks in to the ing, and as the lay com letes its forward movement, the pressure of the filling upon the impinging member moves it forward against the action of the spring 10, and the penetrating member 23 is moved forward in unison, as the softness of the filling penetrated by the prjong 24 is insufficient to dis- "engage or release the latch 25. As the filling is woven off, the diameter of'the mass of filling gradually decreases. and the impinging and enetratin members gradually a roach the barre l of the filling-carrier or befiin. So long as there is a sufficient thickness of filling to act upon the impinging member of the feeler device, and prevent the prong of the penetrating member from contacting with the wood of the filling-carrier there will be no change in the relative positionof the two members of the feeler device, and they will remain locked together by the latch 25.

When, however, the thickness of the remain- ,1

ing filling mass is so slight that the prong 24 engages the carrier 1) before the face 15 mm pinges on the filling, then the penetratm member 23 will have imparted to it an initiad forwardmovement relative to the impinging member sufficient to disengage the latch from thenotch; 29. The members of the feeler device are. now unlocked, and the,

spring 27 actsthrough the latch to press its toe against the-cam surface 28, thereby e1- seams,

position shown in Fig. 4. This secondary movement acts through the lug 22, which is eccentric to the studlrf of the actuator 20, to swing the actuator into operative position, as shown in Fig. 4. When the secondary movement of the penetratingmember is c ompleted, the latch toe entersj the notch 30, and serves to hold the penetrating member from further vforward movement relative to the impinging member. IA link 31islconnected atitsouterend with the upturned-free end of the actuator 20 and atits inner end has adjust ably connected with it-loy a clamp screw 32, 1, atip-piece 33, the tree end of right. guides 35, see Figs. 1 and 6, adjacent the foot 0 of the latch-carrier. The upper 'edge of the tip 33 is beveled at 34, see Fig. 7,

to pass under and cooperate with the corres ondin beveled under face 0 of the foot 0. Vl hen t e actuator20 is operatively ositioned, as has been described, the lin -moved in the direction of the arrow 50, Figs.

1 and 7, the incline or cam 34 passing under the foot of, and 'lfiting it to rock the latchcarrier. 0 into the position shown in Fig. 6. Thereby, the latch 0 is positioned in the path of the shoulder 'w on the weft hammer, and the forward'movement of the latter acts to effect a change or replenishment of filling I by cooperation of the sllde c with the arm d From the foregoing it will be obvious that so long as .there is suificient filling present in theshuttle to permit the penetrating memher to penetrate the filling mass without engaging the filling-carrier, there will be no relative movement between the two members of the fecler device, and saidmembers .Will move back and forth in unison, but as soon as the filling issutficiently exhausted to permit the engagement of the penetrating member with the filling-carrier, the initial relative movement of the feeler members will be effected to unlock them, and the amplified andsecondary relative movement is effected automatically to 'operatively osition the actuator and effect a change in t 1e operation of the loom, such change being herein shown as a replenishment of filling.

To reset the feeler mechanism after fillingreplenishment I have provided the side of the latch-carrier c with an upright, beveled or cam face cfi which wipes across the end of the tip 33 of the link as the slide 0 is moved forward, and pushes the tip and link 31 outward oppositely to the arrow 50, to swing back the actuator 20 from the position shown in Fig. 4 to that shownin Figs.-1 and 2, the toeof the latch .25 being thrown into engage ment with the notch 29 by the action of the spring 27, so that the parts are thus reset automatically, and without any attention on the partof the loom-attendant.
