PROTECTOR MECHANISM AND SHUTTLE CONTROL Oscar V. Payne, Leicester, Mass, assignor to 1 Crompton & Knowles Loom Works, Worcester,

Mass, a corporation of Massachusetts Application August 29, 1933, Serial No. 687,319 g y 19 Claims.

. This invention relates to protector mechanism for looms and it is the general object of themvention to provide means to protect at any one of .a plurality of positions along the shuttle box.

The invention contemplates the use of a flexible element, as a belt,to form one side of the shuttle box, instead of the usual binder. The ordinary protector finger bears against the binderand is pushed out when the shuttle reaches a given point in its travel along the lay. If it is desired to protectlate in the loomcycle. this can be accomplished only by bending the binder to engage the shuttle later. This adjustment neces sarily alters the checking of the shuttle. It is an important object of my inventionto provide a protector indicator movable to various. posi- I tions along afiexible shuttle check the effective length of which is not materially changed by the' setting of the indicator, or time of protecting.

By such. an arrangement the same amount of surfacecontact between the shuttle and its check is maintained regardless of the adjustment for protection.

e The travelling shuttle checking surface can be arranged to move freely in one direction and against resistance in the other direction, and

furthermore the free motion may be either toward or away from the center of the loom. It is a further object of my invention to render the connected to resist the shuttle as it enters the box.

With these and other objects in view which will appear as the description proceeds, my invention residesin the combination and arrangement of partsjhereinafter described and set forth in'the claims.

Inthe, accompanying drawings, wherein a convenient embodiment of my invention is set forth, Fig. 1 is atop plan viewof a lay end having my invention applied to protect/early and withthe shuttle checking belt resisting boxing of the shuttle, t g ,Fig. 2 is a vertical section on line 2-2, Fig. 1, Fig; 3 is a front elevation ofthe structureshown 'plate I l in front of reed l and lies against the shuttle, asv viewed in Fig. 2.

the lay has a stud'45' for the pulley 43.

in Fig. 1, parts being removed for thesake of clearness, andthe indicator shown in an adjusted position in dotand dash ,lines for late protectmg, I

Fig. 4 is adetail horizontal section on line 4-4, Fig.3, v r I Fig. 5 is a detail vertical section'on-line 5-5 ofFig. 1, and W Figs. 6 and 7 are diagrammatic views showing. the control-for the shuttle checking belt, and the protector indicator, in different positions.

Referring to the drawings, thelay'm has a-box front H behind which moves'picker l2 and picker stick 13. The shuttle S moves alongthe race box front when box is as shown in dottedlines in Fig. 1. p a i A protectordagger l6 coacts' as usual with a hunter I! to stop the loom when the shuttleffails to reach a predetermined pointalong the lay at a given point in the loom cycle; The protector rod I8 to which the dagger is secured rocks in bearings on the lay, one of which is shown at l9, while a similar bearing not shown is at the opposite end o-fathe lay. An armZl adj'ustably secured to the rod has a finger 22iprojectinginto; a fork 23 on a second arm Zialdjustably secured to a small shaft25. 'The'latter is rotatable relatively tothe lay in bearings 26 and is held against end motion by collars 2'1 fixed thereto. 30

An arm 28 is mounted on the shaft and held in adjusted angular and longitudinal. position by I a. set screw 29. The upper end of the arm carries I a vertical studtii on whichis rotatably. mounted a roll 3|. Mov'ementof the rollto the right in Fig. 2by shuttle presence will acttodepress the dagger and cause it to clear the hunter as the lay moves forwardly, or to theleft inFig. 2. A

torsion spring 34 surrounds rod 18 and has one end 35 under the .lay' l0 and the other end 36 40 under the dagger IE to lift the latter and also urge the protector roll 3| to the left, or toward the The back of the box is formed inpart by a continuous belt 40 having anouter vertical face v M. Inner and outer guide wheels or pulleys 42 and '43, respectively, are mounted 'rotatably on the lay so that the beltmay travel in adirection substantially parallel to'the. shuttle. To accomplish this result,- a stand -44 on the outer endof I A second I stand 46 for the inner pulley 42 is also on the lay and carries a stud 41 to which is keyed as at 48 a clutch member 49. The latterhas in this instance threenotches 5!] which define wedge shaped pockets 5| with the interior surface 52 of wheel 42. I

Clutch pins 53 are located in the pockets and are the means for effecting a holding connection between the pulley 42 and the fixed clutch member. As shownin Fig. 5, the pins are supported by the stand 46, and the engaging concentricpartsi-of'ithe pulley 42- and clutch member are cylindricahso 'that the latter may "be reversed. I

When the loom is running at a high speed, it is desirable to check theushuttle effectively and also protect as early as possible to allow'time for stopping. Under these conditions, as the shuttle enters the box, it will engage the belt which will be bent inwardlyby spring"34' acting through the roll as shown in fulllines inFigJ'l. The clutch and pins will act tO-z'lBSlSt movement of the belt around the pulleys so thatchecking of the shuttle may result. As the shuttle'conntinues tolrmove itvwillopushi the :-belt rearwardly, :zstraigh'tening itxout tothedotted line position of lrzandathereby-moving the:roll 3 l rearwardly or to the right as seen in Fig. 2. The loom will ;thereforercontinue tor'run. Failure of the uttle to enter the box will leave the roll 3| in forward .iposition, [with resultant. loom: stoppage.
