BOBBIN RECEIVER FOR WEFT REPLENISHING LOOMS Filed Dec. 22, 1945 2 Sheets-Sheet 2 FIG-3 533 A 2o 5l INVENTOR @/HARD G. TURNER A'T'TOR NEY Patented Nov. 12, 1946 UNITED STATES PATENT I oF-FlcE d 2,411,068` j Bomen; RECEIVER FOR WEFT REPLENISHING LOOMS l Richard G. rIlurner,Worcester, Mass., assignor to Crompton & Knowles Loom Works, ,Worceste1-, Mass., a corporation of Massachusetts Application December 22, 1945, Serial'o.V 6v3ii`i9'44 'metal cans which have not only been expensive in construction but Ihave been diicult to handle when being emptied of an accumulation of spent bobbins.` It is an important object of my pres- `ent invention to provide a simpleV form of supporting frame from which a bobbin receiving bag is suspended and mount the frame so that it can be readily' removed andinverted by the attendant when the receiver is being emptied.

Weft replenishing looms ordinarily include in their construction the downwardly and forwardly directed bobbin chuteY along which'the bobbins descend as they are expelled from the depleted The bobbin receiver mouth must exshuttle. l tend behind theforward limit of the path of movement of the chute to insure proper entry of the bobbins into the receiver.'l Because of this fact it is desirable to construct the receiver in` such manner that it must iirst be moved forwardly` clear ofthe path of the chute before it can be raised, and it is another object of my present invention to provide a pivotal? support for the aforesaid frame around which the-latter can be swung forwardly in "advance of the path of the-chute, after which the I receiver can be removed from itsl support.

It is another object of my present invention fto support the aforesaid frame in such manner that the weight of the bag and frame will-be so disposedas to hold the receiver 4normally in bobbin receiving position. This result I accomplish by means of a stationary loom carried support having a stop bar to engage part-ofV then aforesaid frame and hold the bobbin receiving mouth in normal position.

In order to prevent undesirable accidental forward movement of the receiver it is a further object of my invention to provide a form of yielding' lock which will hold `the framework in `its normal rearward position. The lock not only assists gravity to hold the c'e'ivr bobbin receiving position but also prevents upward move- 26 claims. (C1. 13a-255iv chute untilthe receiver has been `moved forwardly a 4safe distance.

When a flexible cloth bag of large bobbin holding capacity is used itis found that the bobbins cause it to bulge and project into the path of the picking mechanism which is ordinarily located immediately behind the bag. It is a further obje'ct of my present invention to provide'a guard jwhich keeps the back part of the bobbin bag from projecting into thepath of operation of the picking mechanism; This guard maybe either a part independent oftheA bag and held on the rbag support, orf it may be built into the bag' in' the form of a reinforcing stiff plate for the back Wallof-the bag; I

When a cloth bag is-inverted for the purpose of emptying it may be dicult to get all the bobbins out of the bag due to sagging of its botwill appear'A as the description proceeds, my infrom which depends a bobbin chute I3.

Referring to the' drawingsi,Y the loom frame lo supports a lay II provided with a shuttlebox I2 During normal loom operation the lay reciprocates backwardly and forwardly and causes the chute to traverse a, given path under the shuttle box.

Weft replenishing operations will ordinarily occur when the lay is at its foremost position or on socalled front center, at which time the spent or depleted bobbins will be expelled downwardly from the shuttle S and will be guided along the chute I3 in a generally forwardly and downwardly directed path.. My presentinventionreh lates to improved preferably removablemeans for receiving and collecting the spent bobbins.

Referring more particularly to Figs. 1 and2 the loom frame has projecting therefroma .sup

in Fig. l and formed withan upwardly-'opening recess I8. The member I1 has on the front side thereof an upwardly and forwardly flared lip or l tongue I9 to provide the recess I8 with a widened mouth. Formed as part of the support-land located above thel member I'I is a cross bar 28- shown in Figs. .1; vand 2. [When so formed the u frame will havegvertical

side members

25 and 26 .locatedrespectively at the right and left as viewed from-the front, ofthe .ljoomrand joined at their bottomsby'` a horizontal` supporting member 21 integral with the side members. The upper ends of. theside memberslEv-and 26 project rearwardly from 4the front of-'the receiver to form downwardlyl and backwardly inclined arms 38 and 3l, respectively, Vthe rear ends of which are preferably-freed. The side members are joined near` .26; is s o located as to extend alongl and infront .ofthe cross bar, v of thesupport frame I5 when f the parts areV in'lfthejposition shown in Fig. 42. The guides V2| and '221;position the side members and 26, respectively, to locatejthe frame as ,shown in Fig.- 1. f Additional forwardly'extending ,guides Y23 on support vl S'may'beiprfvded t0 brace the side members above the guides2I and 22.

vThebag B maygbamade of suitable durable fabric and has right andfjleft sidesand 36a .back wall 3.1 and Va `front wall 38.- These walls are connected at their bottoms toaflatstrip of sheet materialserving-,as a floorv 39 for the bag. The lioor, may b,e cemented or otherwise secured .tothe several walls of the bag. 4

The topsof the right and Yleft-walls 35 and 3S are provided with hems 40 through, whichare slipped the arms l3B and 3|. Thefront wall 38 is provided with eyelets and grommets 42 through which extend attaching cords 43 wrapped around theimembers 25 an126 preferably below the upper cross bar 32 and then knotted.` The outer wall v35` andv frontv wall 38 adjacent-,the forwardright endfof 'the bag are provided with a pair of grom- .mets 45; through which extends a short flexible cord 45 tied around vertical side member 2,5 under cross bar 33. v In similarmanner the inner or left wallzS `and front wall38 are provided with grommets 41 through which extends another flexible 4cord'48 tied around side member 26 under cross .bar 33.` Y. ,j

`A yielding lock* designated generally 'at 1,50 -is 4 lformed of resilient sheet material and is secured at 5I to the cross bar 28 of frame I5. This lock has upper and lower prongs 52 and =53Vthe forward free ends of which are shaped as indicated 5 in Fig. 5 sothat cross Ibar 33 will normally lie between the

prongs

52 and 53 but can pass between the free ends of the prongs when moving forwardly or backwardly.` While I have shown two of these prongs, it should be borne in mind that the bottom prong 53 can be omitted, but the upper. prong is desirable for a reason which will appearzlpresently. Whatever specific form the yieldinglock takes it should have some resilience and shouldpreferably extend over and in'contact with a cross bar 33 when frame F is seated inthe recess I8 as shown in Fig. 2.

A*Under normal conditions the receiver will be in the yposition shown in Figs. 1 and 2 and the upwardlyffacing mouth of Vthe bag designated at M will be positioned to receive bobbins B as they descend alongthe chute I3 incident to replenishing operations-of the loom., ,'Whenit is desired to empty Ythe `bagof its accumulation of spent bobbinagthe attendant will grasp the v`cross tube or bar 32with one Yhand and rock the frame and bag forwardly orjto the left' as'viewed in Fig. 8 during which operation the supportrmember l2Il of the frame F will rock4 in the recess I8 as by a pivotal action. After the frame has been moved forwardly from the ,position of Fig. 2V to that shown in Fig-8 the crosslbar Y33 will be in front of the upper prong" 52, the frame may then be lifted entirely freeof thesupportl5 to the position indicated in Fig. 9. The attendant will then grasp either the bar 33 or the cross member 21 with his other hand and invert thebag` for the purpose of emptying the bobbins into a box or the like not shown moved from loom to loom for lthe purpose. During this emptying operation the

lcords

46 and 48 dueto theirsupport by the'cross bar 3,3wil1-hold the bag against collapsing and will permit Vthe bobbins to move out of the mouth of the .bagwheinr the latter is inverted. Bar 2'I is then reinserted into the recess I8 and the receiver swung rearwardly so that cross Ybar 33 will pass under the top resilient prong 52 and be held by it against the cross bar2ll. v. It willbe apparent from Fig. 2 that when the receiveris innormal Yposition thegreater part of 50 itsv'weight is behind the `cross barl 28 and the receiver, therefore tends tonremaininV `position with the support` member 2.1in1recess I8, .bar 3,3 .againstbar 28, and lateral movement is prevented ,by stops 2| andl22. -QFurther'more,. crossbar33is held against thel bar 20 by the prong I52.v

5.3 lrrorderfto insure proper entryofthe bobbins intothe bag the mouth M mustproject behind the forward part of the path traversed bythe chute. Because-of this fact damage might result if the oyrveceiver were liftedy straight up from the position shown in Fig. 2. To prevenirsuch movement the Aupper prong .52.is made long enough to require the ,frame Fito be-swung forwardly to a position where all Vpartsrof the receiver Will.=be forward of said path before thereceiver can .be raised.V The upeine Prefersdferlii Qite. diei/@eti,6.1.1,lile'fid'y4 described the nflexibilityof the hagmakesdesiralole sedfauaf-. 9- I- 10 f1.9.. wish. .heuer/jef? ieee' d, to .the use# th'. .guard .there ieif, .2Q
