To all 'wlwm'z't may concern: v

Be it known that I, ALONZO E. RHQADES, a citizen of the United States, and resident of Hop'edale, county of \Vorcester, State of Massachusetts, have invented an Improvement in I illing-Replenishing Feeler-Looms, of which the following description, in connection with the accompanying drawing, is a'specification,'like letters on the drawing repre "nting like parts. v This invention relates to looms of the type wherein the filling in the working shuttle is replenished automatically from time to time by or through the instrumentality of feeler mechanism which intermitti'ngly cooperates with and detern'iines the volume of filling in the shuttle and causes-the replenishment of filling when the working shuttle is substantially exhausted.

the feeler mechanism being constructed and arrangedto detect a predetermined degree of exhaustion or diminution of the volume of filling in the shuttle "by or through the diameter of thefilling mass the operative movement of the feeler proper being .efi'ected by or through the shuttle as it-entersthe shuttle-box.

My present invention has provision for detecting a' predetermined degree of exhaustion or diminution of the volume of the lilling in the shuttle by or through the diameter of the yarn mass, in the shuttle, but the operation of the feeler proper, and the feeler mechanism as a whole, is governed or controlled. by means wholly independent of the shuttle, and the various novel features of my 'a portion of an automatic filling replenish- 7 tion- 'of;. the .feeler mechanism; a

present invention will be fully described in the subjoined specification and particularly pointed out in the following claims.

Figure 1 is a left hand side elevation of ing loom of the Northrop type with one form of my present invention embodied therein, the nearer end of the lay, its shuttle-box, and shuttle therein being shown in section; Fig.2 is a top plan view of the mechanism at the left hand side of the loom shown in Fig. 1 and. i'nthe same relative positions as'therein illustrated; Fig. 3 is a' front elevation of the left hand end of the lay with the feeling shuttle-box and a por- Fig.- 4 is a similar view of some of the parts shown in as in la tent Xo.

As willappear by detailed description." hereinafter the feeler is mounted. upon; a support or carrier pivotally connected with .60 I the lay, and the movement of the feeler t0.- ward'and away from the filling in the shut-=- tle is governed by an actuator in sliding 00-. operation with the carrier, said actuator .be-l,

mg mmed Positiwly nd intermitti gly byflcs-c suitable means having a properly timed opeeration relative to other working parts of the loom, more particularly the shuttle and I the lay. .The lay A, the shuttle-box B at the left 1704'2 hand end thereof, the breast-beam 0 having the notched holding-plate D for the ship-=1" per E, the main or cam shaft F, Fig.1, and crank-shaft G, and thc rock-shaftH by 01' I I through which the actuation of the filling''-" replenishing mechanism is elfected, maybe and are all of well known construction and f substantially as in' the Northrop patent re- *f ferred to, the controlling rock-shaft H being the only featureot' the replenishing mocha-"8 nism necessary to illustrate herein. The automatically self-threading shuttle I adapted to receive and hold a filling-car?" rier or bobbin J may be of any suitable charactcr comn'ionly used in automatic re 35 plcnishing looms oi the Northrop type, exccpt that, unlike the shuttles used in ordi nary tcelcr looms, no slot or opening in the side wall'of-the shuttle is necessary in my present invention. In Fig. 2 is shown a rocking transmitter K fulcrumed at L and adapted to effect. the coripcration of a vibrator, such as the i \\'cit-hamn'|er rocleshaft ll is to beturned, substantially; 95.3

789,471 granted 'May I 1905 to Wood and Northrop, the outer end of the transmitter having a cam extension 0. i

with which cot'q'mi-ates a horizontally-swing I ing controller 1 fulcrumed on the ,plateD- at Q. The controller has a' guard R which oven-hangs the cam extension P and the controller moves between the extension and the guard, the frontward swing of. said Conn troller, against its retracting spring S, acting upon the transmitter K to elevate its inner end and place the latch Nin position to cooperatewith the weft-hammerM. .At z its outer end the controller carries an upright, headed stud T on which is pivoted a M, with'a. latch N when the 7:15-

rearwardly extended and upwardly bent dog U having its rear end laterally widened at V, a spring W normally acting to hold the dog in the position shown in Figs. 1 and 2 against the stop-pin X on the controller, the articulation of the dog and controller providing for ease of movement whenby means to be described the dog isengaged and moved frontw'ard to efi'ect the operative movement of the controller and the transmitter K.

Referring now'to Figs. 1 and 2 the'coverplate 1 of the shuttle-box B is provided near.

its inner end withan upright ear havin a transverse bearing 2' for a fulcrum stu 3 fixedlyattached to an arm 4 forming one member of a two-part feeler carrier, :1 secondarm 5 constituting the other member, the stud rocking in the bearing and being held therein by a cotter-pin 6 or other suitable 'device. shaped longitudinally, see Fig.1 3, an outer end is providedwith a cam-slot'7, a frontwardly extended, headed stud 8 being fixedly mounted on the outer end of the said member beyond the cam-slot, and u on said stud is fulcrumed the second mem er 5 of the carrier. v

As shown in Fig. 2 the members 4, 5 are 80 parallel to each other and'to the path of the shuttle across-the lay, the studs 3 and 8 being at right angles thereto and both above the shuttle-box, the parts being so disposed that the carrier member 5 is always posi 85 'tioned over the open top of the shuttle-box 13 about midway between its ends.

- .A. spring 9 is attached at one end to the member 5 and at its other end the springis fixed to the head of stud 8, the spring being 40 coiled around the stud between its head and the front face of the member 5, see Fig. 2, the winding ofthe spring being such that when free to act it depresses the member 5 upon a lateral shelf or stop 10 projecting from the outer end of the inner member 4,

as shown in Fig. 4. The inner end of memher 5 has a'lug-ll depending therefrom to .engage theinner end of thestop 10 and limit the upward swing of said member on the fulcrum stud 8 when the feeler contacts with a full or nearly full bobbin in the shuttle. The member 5 is also provided with an inwardly extended perforated ear 1 12, and the member 4 adjacent said ear has a hole 13, Fig. 4, the purpose of which will be referred to.

Herein I have shown the feeler proper as integral with the member 5,,and to this end the outer end of said member is downturned at 14, Figs. 1, 3 and 4 and is shaped to present a yoke-like. feeler 15 shaped like amin- 'verted U, the depending legs thereof being adapted to engage the filling Y on the bob bin at points equidistant from the longitudinal axis of the latter, see Fig. 1, when the The member 4 .is slightly V- its feeler 15 to position the hunter substantially feeling stroke or. movement is imparted to the feeler. In other words the feeler 15de-- tects a predetermined degree of exhaustion or diminution of the volume of filling in the shuttle by or through. the diameter of the yarn mass, the effective distance between the legs of the feelerbeing determined beforehand so that the downward or-feeling stroke of said feeler is never completed untilthe diameter of the yam-mass on the bobbin is less than the distance between'-. the feeler legs, and when this conditionof affairs is present the full downward stroke of the feeler isaccomplished. Y

It may be stated here that the carrier member 4 has a-constant stroke, but by reason of't-he gradual diminution of the filling 1n the shuttle the downward stroke of-the member 5 gradually increases up to the full stroke, the member 5 swinging on it's fulcrum 8 relative to member 4-while also hav-' mg a bodily movement with said member 4 about the fulcrum 3. The spring 9, which is a light one, resists the relative movement of the two members and acts to place them in the relative position shown in Fig. 4 0113;; everyupward or retracting stroke Qf the carrier about its fulcrum 3. As shown in Figs. 2, 3 and 4 the depending legs of the feeler-are quite broad, so that the filling-contacting edges thereof are long enough to engage a considerableiportion of the filling each time the feeler is caused to contact. therewith, thus distributing the strain of impact upon the yarn and preventing injury thereto. 4

A frontwardly' extended; bunter 16 is fixedly attached at 17 to this member 5 of. the carrier, at a pointopposite the widened end V of the dog'U, butthe bunter is not permitted to engage said do until the 'predetermined'exhaustion of. 51s filling-- ermits a sufiicient downward movement-o the on a level with the dog. 11o

Referring now to Fig. l the loom side has mounted upon it'back'of thelay a bracket 18 having a horizontal stud 19 on which is ful'crumed the actuator 20 for the feelercarrier, said actuator being shown as a preferably round and rigid bar longitudinally curved and extended over the lay transversely thereto, and passing through the cam-slot 7 of the carrier member 4. Saidactuator is of such length that it extends through said slot in all positions of the lay, so th t there is a sliding en agement between the actuator and the' eeler-carrier and the latter is thereby continuously controlled or governed by said actuator.

A rearward extension 21 of. the actuator is pivotally connected at 22 with a depending link 23 provided'with a roller or other suitable stud 24 which coiiperates with the groove in a cam25 fast on the shaft F, a 9

1,oio,279 8 short radius arm 26 being pivotally connected at one end with the link and at its other end being fulcrumed at 27 on a stand 28 mounted on the loom side. The radius bar prevents improper swinging movement of the link 23 while permitting it to. rise and fall as the cam 25 re-' volves,'to effect the positive and intermittent oscillation of the actuator 20, and pref- .merably'the link is made in two parts, as

shown, for longitudinal adjustment, a common form of construction.

As the shaft F makes one revolution for every two revolutions of the crank-shaft G the groove of the cam 25 is laid out to present a long circular or dwell portion from '29 to 30, (reading opposite to the direction of rotation indicated by arrow 50) equal to about three-fourths of a revolution of the cam, and with a gradual but rather rapid rise from 30to the high point 31, and a somewhat more rapid drop from such high point to the beginning of the dwell at 29.

\Vhenjhe follower 24 is traversing the dwell port-ionof the cam the lay swings back, forward, and back while the actuator 20 is quiescent at: itshighest position, and

preferably the curve of the actuator is at this time an arc whose' center is coincident with the lay rocker-shaft, and during such time the shuttle has been picked to the right, the filling has been beaten in, and the shuttle has been picked to the left, to box 15, on the second backward swing of the lay in readiness for the feeler to act. Now, as the lay is moving forward, Fig. 1,'with the shuttle in ,the left-hand box B thelpart 30 to 31 of the' cam operates through the follcwcrand the link 23 to quickly depress the Q10 actuator-20, and consequently the two-part feeler carrier-is swung downward on its fulcrum as the lay moves toward front center. If there is sufficient filling present to stop the feeler 15 in its downward movement the jointed carrier is 5 broken at the pivot stud 8, while the member 4 completes its full down stroke, such a condition bein shown in Fig. 3, and as the feeler is arrestefl by'the filling the hunter 16 will be moved forward with the lay in a path above the (log T The follower roll 24, after passing "the high point 31 of the cam, is quickly depressed by the cam portion between 3l'and 2!), Fig. 1, the dipping movement of the actuator and the feeler carrier being completed before the shuttle is picked from the box B after the beat-up is completed, but the rise of the feeler carrier does not occur until the hunter 16 has had an 'opportunity to engage and push the dog U frontwardas the lay moves toward front center.- Now let it be supposed that the filling has been diminished -'o such an extent that the diameter thereof is just small enough to permit 5 the feeler 15 to pass downward at opposite sides of the bobbin. When the previously described depression of the actuator is effected thefeeler carrier will swing'downward and as the filling offers no obstacle to the feeler 15 the latterwvill descend its full distance, thetwo members-4: and '5 ofthe carrier moving down together without any relative movement, and the hunter 16 will be moved down therewith so that as the lay beats up the dog U will be engaged by'the hunter and pushed forward before the part 31, 29 of the cam comes into action. Such forward movement of the dog is communicated to the controller 1* and the latter in turn acts upon the cam-extensionO and rocks the transmitter K, positioning the latch N for engagement by the weft-hammer M, which at this time is moving forward. T hereupon the rock-shaft H will be turned and the operation of the 'replcnish- 35 ing mechanism will'be' effected when the shuttle I is in the right hand shuttle-box,

in amanner familiar to those skilled in the art. \Vhen the described cooperation of the hunter and the dog .is effected the parts remain in engagement only long enough to provide for the proper movement of the controller 1?, and the part 31, 29 of'cam 25 acts to elevate the feeler carrier audits adjuncts before the shuttle is picked from'the box B.

It is sometimes desirable to throw the feeler mechanism out-of operation without disturbing the other parts of the loom, and.

to do this all that is necessary is to swing up the carrier member 5 until the perforation in its car 12 registers with the hole 13 in member 4, and a pin is pushed into. thev registering apertures, holding the member ,5 up far enoughto prevent any operativej engagement of the feeler 15 with the filling. From the foregoing description it will be apparent that the operation of the feeler mechanism is effected wholly independent of the shuttle, the intermittent movement of the feeler into and out of the shuttle being effected positively on every alternate ick, and as the spring controlling the jomted, feeler carrier is of low power the feelin action is delicate and has notendency to 11. damage the filling.

Various changes or modifications of different features of construction and-arrangement may be made by those skilled in the art without departing from the spirit and scope of my invention asset forth in the annexed claims. I

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is: x 125.
