FILLING-SUPPLY LOQlVl.

I SPEOIFIGATION forming part of Letters Patent No. 662,4d1, dated November 27, 1900. Application filed January 2, 1900. Serial No. 52. N0 model.)

Looms provided. with automatic iilling-sup-Yv ply mechanism have devices which arejin tended to operate, when the filling is broken or exhausted, to provide the loom with a new supply of filling while the loom is in motion. This has been accomplished by substituting for the shuttle in theloom anothershuttlecarrying a new supply of filling, or by providing the shuttle in the loom with a new supply of filling, or, in other words, by changing the shuttle or by changing the bobbin in -the shuttle. These looms have a filling-supply detector on one side of the warp which controls the actuating devices of the filling-supply mechanism. The absence of filling causes theldetector to set the filling-supply mechanism in motion to renew the shuttle or the bobbin, as the case may be. Provisions are usually made toprevent the taking up of cloth when the filling is absent for apick or part of a pick and to stop the loom'when the filling-supply mechanism fails to provide filling. It sometimes happens that the filling will break at some distance from the shuttle and that the trailing end will be interposed [objection in some forms of automatic fillings supply looms that it has been doubted whether they accomplish a useful saving in the expense of weaving. The thin stripe may also be caused by the clogging of the filling-supply-detector fork.

The object oi my invention is to reorganize and improve the automatic filling-supply loom to overcome the objectionable production of thin stripes in weaving,

To the above end the present invention consists, broadly, in theautomatic filling-supply loom having provisions for stopping the loom if for any reason the filling-supply detector fails to indicate the ahsericeof filling.

My invention contemplates providing an automatic filling-supply loom with a fillingsupply detector on one side of the warp adapted to control the filling-supply mechanism, and a illling-stop detector on the other side of the warp to stop the loom in the absence of filling when the filling-supply detector for any reason fails to operate. v

My invention contemplates providing an automatic filling-supply loom with two fillingdetector mechanisms, one on each side of the warp, the one having provision to set the filling-supply mechanism in motion and iheother having provision to stop the loom, and connecting devices between said detector -iuechanisins operating to prevent the stopdetector mechanism from stopping the'loom when the filling-supply detector operates to set the filling-supply mechanism in motion.

My invention also contemplates certainother features and details of construction hereinafter described, and pointed out in the claims.

It is to be understood that my invention is broad and generic in character and by no? looms above'referred totl1at is to say, it is adapted to those looms which operate by changing the shuttle as Well sis-those Whichoperate by changing the bobbin in the shuttle.

The-specitlc form of loom which I have v illustrated in the accompanying drawings is, the well-known Northrop loom, in which the ion scription I have shown and described the -form of the invention which I prefer and nearer the warp when the shuttle is boxed at- "the opposite side of theloom from, the fillingsupply mechanism, so therefore a trailing thread extending from theshuttle to the fillingsupplydetector will prevent the fillingsupply mechanism from .being set in motion.

OfQcourse if the trailing thread were long enough to extend into the shed it would be beaten up by the reed and weaving wou'lfl be resumed. If. the thread should break at the salvage, it .Will' be seen that'the next time the shuttle was boxed at the opposite side'of the loom to. the filling-supply mechanism'the- '25' trailingfithreadi'wouldextend up vto.,these1- vage,',afu "thju sbe' interposed between the the-lay, and prevent. the; detector fro|nset ting the filliug-supply mechanism{in motion; 31f, on the other, hand, 'the thiead shouldbreak; not at the salvage butb'etween' the and thus prevent the-making of thin-stripes.

In the accompanying drawings, illustrating the preferred form of my invention, Figure 1' is a frontelevation of a portion of the Norcordance with my invention. Fig. 2 is a side elevation of the loom looking from the fill- ,ing-supply mechanism side with parts of the connections between the stop-detector mechanism and the take-up mechanism.

of which lever is to permit the till. m-

shuttle enters the shuttle-box under the filling-eupply mechanism, nor on the beat of the lay immediately after the filling-supply detector has operated to set the fillingeupply mechanism in motion, and so I employ here a detector operating to stop the loom on the second absence of filling, and l furthermore provide connections between this filling-stop detector and the filling-supplydetector operating to render the slop-detectorinoperative when the filliug-supply detector operates to set. the filling'supply mechanism in motion. So in case of the occurrence of a. trailing thread the stop-detector would operate to stop the loom.

Having thus described the general features of my invention in its broader aspects, 1 now proceed to a description of the specific forrn shown in the accompanying drawings.

1 have shown in the drawings only so much and such parts of the Well-known Northrop loom-as is'necessary for a clear understanding of the cooperation therewith of my improvement.

The frame 1 supports the operative parts of the loom. The breast-beam 2 has the pro jection 3, which altordsa guide for the shipper-lever e and it support for the knock-cit 16VQT'5. The filling-supply detector 6 is constructed substantially as illustrated and described in patent to Northrop, No. 529,9i3, and operates in the manner therein described to set the filling-supply mechanism in action and to stop the loom when the filling-supply is exhausted. The filling-suppiymechnnisin 7 is constructed substantially as shown in patent to Northrop, No. 568,4:55, the lever 8 corresponding to the lever show n separately in Figs. 5 nndfiof said patent, the function -snpply dog to be raised by its spring into position to The detector shaft 9 is operated by the filling-supply detector, as described in said Patent No. 568,455, through the lever 10, secured there- 'to. Upon one end of the detector-shaft 9 is secured the lever 11, which carries on its end the slotted linlt 12, which operates in the usual manner to permit the ieverS to he moved by the fiiliugsupply dog. (See patout to Northrop, No. 568,455, wherein the lever dined slotted link oi'fcorrespond to the lever 11 and slotted link 12 herein.) Upon the other end of thedetector-shatt E is mount ed the leqer' 13, which, by engagement with the projection 15 on the pawl-carrier ls lifts the pawl 16 out of engagement with the ratchet in the manner described in patent to Northrop, No. 610,636. The take-up deric es 17 are 'Ljehstructed substantially as de scribed in hrd patent. The lay 18, the swords 19,,iih'e p itmen 20, the let-cit, the shedding mechanism, and the Warp-stop de vices are otany usual or preferred form.

Upon the side of the warp adjacent to the fiiling'supply mechanism is mounted the iilliillin -stordetector slide is returned to its normal position by a spring, :21, of which one end is attached to the slide and the other to the slide-support. Loosely mounted on a suitable support, the detector-shaft f), is a lever 22, which has its upper end opposite the pawl 3-5 of, the tillingstop detector. A spring 2i tends normally to hold the lever in the position shown in Fig. 2. A red 25 is secured to the lower end of the lever 22 and it carries upon its rear end the wedge 26, which when it is moved rearwardly is adapted to raise the stop-rod 27 in'fron'i of the warp-feeler 28.- The stop-rod 27 is slid ingly mounted in a-guide 29, secured in any suitable manner to the member 30 of the frame of the loom. Thus when the lever 22 is oscillated by the filling-stop detector it operates to lift the stop-rod 27, so thatthe feeler 28 will engage itand. the loom will be stopped tllereby in the usual manner. which illustrates the conneotionshetyreen the feeler 28 and the knock-oft lever i of the Northrop loom and which is suhstantiuily the construction illustrated in the patent to Draper, No. 618,378.) it is tohe understood that the filli-ng-stop detector may be arranged to connect with any convenient means of stopping the loom and that the arrangement which I have shown and described is a convenient one and the one which I prefer;

The weft-hammer ill, its book 2, and the 02111133 operate in the same manner as the Weft-hammer for the filling-supply detector, the cam 33 of course being; mounted upon the cam-shaft 25% at one hundred and eighty de grees of angle to the position occupied by the cam which operates the Weft-hammer of the v fillingsupply detector.

From the side of the pawl 35 of the tillingstop detector there urojects a pin 3b, which is adapted. to he eng .n by a Wire 37, pivotally mounted on the hr b" beam and having an end 38, projecting in front of the hook 3905 the lever 8. This wire 3? is clearly shownin Figs. 1 and. 2.

' he operation of the filling-stop mechanism is as follows: Let it be assumed that the loom is running properly and weaving cloth and that thereupon. the bob'oin of the shuttle hecorees exhausted or the filling breaks, and first let it be assumed that there is no trailing thread and that the fillingbroke or necameexhnusted on the motion of the shuttle through (See Fig.6,

the shed away from the filling-supply mechanisni. lhe absence of Weft will be indicated by the filling-supply detector, and its wefthnmtner will. move the slide -10 forwardly, s'o

that its end shall engage the lever 10, thereby oscillating the d etectonshaft 9. This oscillation of the detector-shaft will set the fillinc-supply m rlmnism ii: f'l tion, because it will raise therear end of the' lever. 1-1 and raise the slotted link 12, and thereby permit the lever 8 to be moved by thespring on the dog of the filling-supply mechanism. The

l shuttlc will! now be thrown into the shuttlebox underthe filling-supply mechanism, and

on the next, beat of the lay the absence of. filling will be indicated by the'filling stopdetector 21,:1.nd theweft-hainmerBl will push the 1 filling-stopsliderearwardly and remove the wedge, 351 from under the pawl 35, thereby --per'mittingits operative'eiid to be dropped low enoughtoengagethe lever 22.0n the next reciprocation of'the slide. The filling-supply mechanism would at this timepperate to pro- "vide' a" new "supply of fillingand sc on the next forward motion of the'weft-hammer the weft-forkwouldfbe filted and its hook would fail to engage the weft-foltk, the slide would 2 stand still, and the hammer would push thea wedge under the pawl 35 and restore it to its normal position. If, however, the filling had 1 "broken or become exhausted, as the; shuttle wasvpassing through the shed in the direcs3 5 tion to enter the shuttle-box under the fillingvsupply mechanism, such mechanism would not at this time operate to put a new bobbin inthe sh'uttle,'but the shuttle would be thrown across to the oppositeside of the loom, and

then the filling-su'pply detector would operate to set the filling-supplytmechanism in motion to insert anew bobbin the next't'ime the shuttle reached the box underthe filling-supply mechanism. So, therefore, in this case on the first 3 5 beat of the lay which would indicate an ab;

sence of weft opposite the filling-stop detector 21 the only operation would be the dropping of'the pawl into operative position toen gage the lever 22. 'lhenjthe filling-supply '40 mechanism would be set in motion by the filling-supply detector and the oscillation'of the lever 8 would actuate the wire 37 to lift the pa 135, so that'on second absence of weft op-.

- posits the filling-stop detector the pawl would be lifted by the wire, so that it should not engage the lever 22 on this reciprocation of the slide and the loom would not be stopped. The bent wire 37 constitutes what may properly be called a stop-preventer, since itoper- 5o ates to prevent the stopping of the loom when the filling-supply mechanism has been set in motion bythe filling-supply detector.,, On

v the occasion of a traili n g thread the fillingsup ply detector would fail to indicate the break in the filling, but the fillingstbpdete'ctor would indicate it, and the first: reciprocation of the filling-stop-detector slidewould operate to-drop the pawl 35 in position toen gage thelever 22, and the next successive reciprocation '60 of the filling-stop-detector slide would cause the pawl to engage thelever 22 and stop the loom, because the stop-preventer mechanism would be inoperative to lift the pawl 35 byreasdn of the'fact that the filling-supply mecho5 anism had not been set in motion byfthefilling-supply detector. I

The ordinary. Northrop loom is provi'ded I with a letting-back mechanism for the take cut to Draper and Northrop, No. 678,838, which lets backthe take-up'to allow for the .absent weft-thread. This loom is also prodescribed, for lifting the pawl of the take-up ,mechanism, and Lhave found it desirable in stopped by my filling-stop detector. To this end I have mounted in suitable bearings 41 on therear of the breast beam the rock-shaft 42-, to which is secured at one end the lever 43, having the pin 44 at its end which is engaged by the dependent end of .the lever 22, so that when the lever 22 is oscillated it will cause a From the other end of the rock-shaft .42 there projects the lever 45, which is adapted to engage the pinv 46, mounted in the side of the pawl-carrier 14. Thus it will be seen that when the filling-stop detector operates to stop the loom the pawl-carrier 14 will be elevated so as .to disengage the pawlflfi from the ratchet up will be stopped just before the stoppingof the loom, so that when the loom is started again the fell will occupy its correct position to receive the filling. Having thus described in its generic ,character and in thespecific form in which I have embodied it, I claim as new and desire to secure by Letters Patent of the United Statesv 1.
