FILLING DETECTOR FOR LOOIVIS.
To all whom t may concern:
Be it known that I, .losErH E. ROCHETTE, citizen of the United States, residing at Norwich, in the county of New London and State of Connecticut., have invented certain new and useful Improvements in Filling Detectors for Looms, of which the following is a specification. Y
The present invention relates to filling detectors or feelei` mechanisms for effecting a change in the operation of a loom when the filling in the active shuttle has become nearly exhausted.
Detector mechanisms of various typesv have heretofore been proposed for feeling into the shuttle during the operation of the loom, and upon the occurrence of substantial exhaustion of the filling in the shuttle, setting into operation mechanism for effecting replenishment of the filling supply. In some types, the Vdetecting means has consisted of two members, one an impinging member to contact with the filling in the shuttles, and the other a penetrating'mem-` ber to sink into the filling on each detecting beat-up movement of the lay and upon the occurrence of substantial Yexhaustion of filling, these members havecooperated to initiate filling replenishment.
In detector mechanisms comprising an impinging member and a penetrating member it is desirable that there should be capacity for the relative adjustment of the two members toward and from the lay in order to determine the most advantageous degree of penetration of the penetrating member with respect to the particular yarn or filling on the bobbin or carrier in the shuttle.
An 'important feature of the present invention therefore consists in providing a filling detector of the impinging and penetrating type with means for relatively adjusting the two members bodily toward and' from the lay.
As well understood by those familiar with those devices, the detecting action and initiation of filling replenishment must be effected in a very small fraction of time, during the detecting beat of the lay. Therefore, simplicity of construction and operation conduce to a more 'accurate accomplishment of the desired end.
Another v important feature of the invention, therefore, consists in operatively positioning -the means s for initiating ref Application filed September 27, 1923. Serial No. 665,038.
plenishment by simple and positive means,
which, in the embodiment of the'invention here illustrated, comprises arocke'r in thel form of a belly crank whichmay be'turned uponits axisthrough a small arc When the penetrating member strikes the' more dense substance ofthe filling carrier or bobbin.'
Anotherobject of the invention is to generally simplify and improve devices of the above kind whereby the same may meet with all of the krequirements for a successful commercial use.
Other features of the invention will b hereinafter described, in connection with the illustrated embodiment of the invention,
and then definitely set forth in the claims.`
In the drawings:
Figure 1 is a view, partly in plan and partly in section of the illerdetector, showing the action of the impinging and'p'e'ne'- trating members when a working supply of filling is present in the shuttle. l p Figure 2 isa plan view, similar 'to that of Figure 1, showingthe p'ositionof parts perspective view of the bell .invention is adapted to be applied to a socalled filling replenishing or automatic loom, wherein,rupon substantial exhaustion of the filling inthe shuttle, means are set in operation toeffect a replenishment of the filling.
The replenishment mechanism and its general characteristics and operations, as well as the parts for initiating its operation under `the command of the detecting mechanisms are well understoodby those skilled in `the art, and detailed explanation thereof is un- 'y necessary.
The shuttle A ing 5 in its side wall and the shuttle box will. have its front wall provided with an S is provided with an open- .80 on the beat-up movement whenthe filling opening, the said openings of the wall of the shuttle and the shuttle box being adapted tof register when the shuttle is properly positioned in said box for the action of the detector mechanism. These features also are common and well understood.
The filling detector comprises a stand or base plate 6 which may be properly secured to a suitable portion of the loom frame, in which the detector is to be used by the means of screws or the like, and is provided with bearing portions 7 and 8 in which is mounted the feeling carrier 9, the forwardly extendingstem portion of which is under the control of a suitable spring 10 normally tending to force the feeler carrier rearwardly or toward the lay. In 'the present instance'of the invention, the feeler is shown as a slide andthe spring 10 surrounds the stem portion ofthe feeler and at one end is seated against the bearing 7 and at the other end against the slide block 11 that is fixed upon the stem portion of the feeler 9 as clearly shown in the severall views.
The term feeler slide is herein employed in its broad sense as a part for carrying the feeler members and movable toward and away from the front of the loom. f
, The feeler slide 9 has at its rear portion, animpingingmember 12,'in the form of a laterally directed endof said feeler slide, and which, when V"the shuttle is in the box at the detecting side of the loom is adapted to enter and contact with the lilling or filling carrier in the shuttle.
Extending through the iinpinging meinber 12 of the feeler slide, is the penetrating member 13, the penetrating end portion of which is preferably formed by reducing the rear end' of said penetrating member so as to provide a shoulder as at 14 for limiting the penetrating movement of the member 13 through the head 12, opposite side of the free end portions of the needle thus produced being bevelled so as to provide a knife edge, as
vRising from the slide block 11 of the feeler slide rod 9 is a lug 16, in which is mounted the stud 17,'on which the bell Ycrank rocker 18 is pivotally mounted. vAs shown in the several views, the lug 16 is provided upon the inner end ofthe blockv 11, and thestud 17 extends transversely of the base plate 6 and through arcentral opening -19 provided at thc juncture of the arm of the bell crank rocker 18, said vrocker being disposed with anupwardly extending arm, and a forwardly7 pro liecting lower arm. The free Vend portion of theflower arm ofthe rocker 18 is provided with a notch as at `2O, which is adapted, at times, to engage a controller operating'lever 21, for initiating iilling replenishment when such feeler is moved toward the front of the loom while engaged 'V with: the controlling operator lever 21. p t
In order to control the operative or inoperative position of the rocker 18 with respect to the controller operating lever 21, a coiled spring 22 is provided upon the stud 17 between the lug 16`and said rocker 18, one end of the spring being passed into an opening 23 provided in the'lug 16, and the other end of said spring being passed into an opening 21 provided in the lower arm of said rocker 18 whereby the'spring 22 normally;
causes the rocker to swing to a position wherein the lower arm of the latter is normally horizontally positioned in a plane above the rearwardly extending sharpened endY 25 of the lever 21.
The upwardly extending arm' ofthe rocker 18 is provided with a transverse opening 26 in which is secured a stud 27 Vand this stud is provided with a transverse This'end 29 is screw threaded asshownto receive nuts 30 thereon at opposite sides of the stud 27, whereby the penetratingv member is rigidly fastened tothe stud'v27. Obviously, the stud 27 may have a reduced end portion which enters the opening 26 and which is threaded for reception'of a nut 31, whereby the stud 27 is rotatably mountedv in the upwardly extending arm of the rocker 18,and Vwhereby the device Vmay be con-A structed at this point Vfor being readily* assembled'or repaired. Also, by loosening the nuts 30, the position of the Ypenetrating member 13 relative to the impinging arm adjustmentmay be secured ing said nuts 30. Y
The bearing 7 Vis preferably forinedof an integral structure, while the bearing 8V may be provided with a removable cover plate held in place by means of screws orthe like as at 32, thus enabling ready assembling of the feeler slide rod`9 and the base plate 6.1`115 The lever 21 is ofgeneral'bell crank form and pivotally mounted upon a vertical stud 33 Vixed to the -b'ase plate 6 rearwardly of k or head 12 may be adjusted, after which the` Y by again'tighten-VV the rocker 18 for swinging movement in ai" horizontal plane, the inwardly extending arm of the` lever 21 being formed with theV rearwardly directed tooth 25 vabove menizo Y tioned, and the other `or'forwardly'projectt ing arm of said lever 21 being provided I with perforations asY at 34 for adjustable connection with the usual'controller operaty ing rod. The lever 21 is yieldingly swung to and held in its normal operative position by means of a helical tension'` spring 35, connected to the inwardly extending arm'of said lever 21, as at 36, and having its outer From the above description, it will seen that thevspring 22 notonly serves to hold the rocker 18 in a normal position with the forwardly extending arm thereofV out of the path of the tooth 25 of thelever21, but
also serves to hold the penetrating member 13 in its rearward position wherein the same is projected with respect to the impingingk member or head 12.
From the above description, it is apparent that the spring -will hold the arm or head 12 against filling as shown in Figure 1, while the spring 22 will cause the penetrating member 13 to be projected for penetrating said filling of the filling carrier. However, when the filling becomes practically exhausted as shown in Figure 2, and the penetrating ymember engages the more dense substance of the bobbin or filling carrier and is thereby moved forward on the beat-up movement of the lay, the penetrating member turns the rocker 18 upon its pivotal mounting 17 and thereby moves the lower arm of said rocker 18 to bring its bifurcated end portion as at 20 into lowered position for engaging the controller operating lever 21, or, specifically, for engaging the tooth of said lever 21, when the detector or feeler slide is moved toward the front of the loom.
From the above description, it will be apparent that upon turning movement of the rocker 18, due to the penetrating member of the detector engaging the dense substance of the filler carrier or bobbin, such rocker is turned upon its axis to thereby position the lower arm of the rocker 18 operatively and initiate filling replenishment upon the forward movement of the detector.
The construction is simple and effective and the parts so related that within the small space of time allowed for the action of the detector, upon substantial exhaustion of filling, the parts may resume the desired relation for initiating filling replenishment.
